Detailed Description

The core of the application is to provide the method and the device for starting the engine. Starting the engine at rest reduces wear on engine start. And in the running process of the vehicle, the engine is started to run after idling for a period of time, so that the problem of engine oil emulsification of the vehicle is prevented or reduced. Meanwhile, a method for recovering kinetic energy of the vehicle is provided.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a method for starting an engine provided by the present application, the method for starting the engine including:

as shown in fig. 1, the method includes:

s101, the user unlocks the door of the vehicle outside the vehicle;

the user remotely controls the vehicle door of the vehicle to be unlocked through a remote control key or unlocks and opens the vehicle door through a mechanical key. And (4) unlocking the automobile door, and directly opening the automobile door through a handle on the automobile door.

Specifically, the vehicle door is unlocked, and the user does not get on the vehicle. The relay turns on an electromagnetic switch of the starter motor. And after the electromagnetic switch is turned on, the starting motor is electrified and operated. At this time, the engine oil supply pump is not supplied with oil, and the spark plug is not discharge ignited.

S102, after the vehicle door is unlocked, starting the starting motor in the engine, wherein the starting motor drives the oil pump to run and supply oil; the oil pump provides engine oil for the surfaces of all parts of the engine for lubrication;

after the vehicle electric control device receives the vehicle door unlocking information, the vehicle electric control device starts the starting motor of the engine, and the starting motor is electrified to operate to drive the engine piston to operate. And meanwhile, the engine oil pump is driven to operate and supply oil. Before the engine is started, engine oil flows or splashes to the surfaces of all parts of the engine through an oil passage through the engine oil pump for lubrication. Wherein, include: the cylinder wall inner surface is also lubricated by the oil splashed thereon. When the engine is not started, the engine oil is firstly started to drive the engine oil pump to operate, so that the engine oil lubricates the inner wall of the cylinder body. When the engine is started to run at idle speed, the abrasion of the engine during starting can be reduced.

Specifically, the starting motor drives the engine crankshaft to rotate, and the crankshaft drives the engine piston to operate. Meanwhile, a camshaft in the engine rotates, the camshaft drives the oil pump to operate, and the oil pump provides engine oil lubrication for all parts of the engine. Meanwhile, the oil pump sprays the engine oil to the inner wall of the cylinder and moves up and down along with the piston, the piston ring and the oil scraper ring scrape the engine oil on the inner surface of the cylinder wall uniformly, and a uniform oil film is formed on the inner surface of the cylinder wall. The oil film serves to prevent the engine from being worn away when the engine is started. The vehicle electric control device is an integrated circuit which is used for controlling software and electronic equipment for controlling the operation of the engine of the vehicle and executing various information commands. Which may be understood as part of the vehicle ECU arrangement.

S103, starting the engine when the user enters the vehicle, and enabling the engine to run at an idle speed;

when the user enters the vehicle, the engine is started by a key starting button or a key, and the engine is normally ignited to run. At this time, the starter motor is driven by the engine. Or the starting motor stops working. And after the engine starts to run at the idle speed for a period of time, driving the vehicle to run forwards.

And if the user does not start the engine after the starting motor operates for a set time, the starting motor automatically stops working. And starting a timer, taking the stop time of the starting motor as a starting time, and if the user starts the engine of the vehicle through a starting button or a key in the vehicle within a specified time, the vehicle directly starts the engine ignition operation. Because the engine oil on the inner wall surface of the cylinder wall of the engine can not fall off within a certain time range, the inner surface of the cylinder wall still keeps the oil film to protect the engine. At this time, the engine may be directly started. At this time, the engine will be started directly, regardless of whether the vehicle door lock is closed or unlocked again. And in a specified time, the unlocking of the vehicle door will not start the starting motor to operate and drive the oil pump to supply oil.

Specifically, when the user enters the vehicle, the engine of the vehicle is started by one key of a start button, or the engine of the vehicle is started by a key, and the engine is normally started. The engine is ignited to run, and the engine piston moves up and down. Meanwhile, the oil supply pump starts to supply oil, the air inlet starts to admit air, atomized gasoline is sprayed into the cylinder to be compressed together, the spark plug discharges and ignites, and the engine works normally. Meanwhile, the storage battery or the battery pack in the vehicle stops supplying power to the starting motor, and the timing belt or the timing chain of the engine drives the starting motor to operate and generate power, and charges the storage battery or the battery pack of the vehicle.

S104, when the vehicle is the hybrid vehicle type and the navigation function of the vehicle is not started during running, the vehicle is driven to run by a driving motor or the vehicle starts the engine to run at an idle speed or the engine drives the vehicle to run according to the change of the vehicle speed; confirming the restart time of the engine through a timer;

and when the vehicle is the hybrid vehicle type, the engine and the driving motor drive the vehicle to run together. And the vehicle does not start the navigation function, and the vehicle running speed does not reach the first speed, and the vehicle is driven by the driving motor to run forwards. And when the running speed of the vehicle reaches a first speed, starting the engine to run at an idle speed, and simultaneously, continuously driving the vehicle to run forwards by the driving motor. When the vehicle accelerates to a second speed, the vehicle is converted into the engine-driven running; wherein the first speed is less than the second speed. The engine runs at idle speed, and the whole engine is heated, so that the problem of engine oil emulsification of the engine is prevented or reduced. The engine in idle operation generates electricity through the engine, and the electric energy is stored in a battery or a battery pack of the vehicle.

Specifically, the hybrid power vehicle runs at a speed of less than 70 km/h, and the vehicle is driven to run by a driving motor. And when the running speed of the vehicle reaches 40 km/h, starting the engine to run at an idle speed. When the vehicle running speed is more than 70 kilometers per hour, the vehicle runs under the driving of the engine.

S105, when the vehicle starts the navigation function, according to the vehicle navigation positioning information and the predicted road passing condition in front of the vehicle, the engine starting condition is met, and the engine is started to run at an idle speed in advance.

And when the vehicle is the hybrid vehicle type, the engine and the driving motor drive the vehicle to run together. And starting a navigation function by the vehicle to position the vehicle. And predicting whether a road in front of the vehicle in the navigation route is smooth, whether a second-speed running condition can be met and whether the road in front is allowed to run at a second speed according to the vehicle positioning result. If the conditions are met, the electric control device estimates the time of the vehicle reaching the smooth road section, starts the engine to run at idle speed in advance within a reasonable time range, and changes the driving motor to drive the vehicle to run into the driving motor to drive the vehicle to run after the vehicle reaches the smooth road section and the vehicle is in an acceleration state.

If the vehicle turns on navigation and initiates the engine idle ahead of time, however, the vehicle speed does not accelerate to a second speed. At this time, the engine operation mode when the navigation function is not started is executed, that is, whether the engine continues to run at the idle speed is determined according to the vehicle speed. When the vehicle has not reached the second speed after the engine has been running for a prescribed time, the engine is turned off. And providing power for the vehicle to run at a low speed by the driving motor.

In the idling operation process of the engine, a generator or a driving motor is driven to generate electricity, and the generated electricity is stored in the vehicle storage battery or the vehicle battery pack. The generator is an independent device and is driven by the engine to operate. Or the generator is a driving motor, the engine drives the driving motor to operate and generate electricity, and the driving motor provides driving power for the vehicle during low-speed driving. Further comprising: and the engine runs at an idle speed, and the vehicle storage battery or the battery pack is charged by the starting motor.

Specifically, when the navigation system of the vehicle is used for navigation, or the mobile phone is started for navigation and is connected to the vehicle intelligent system, the navigation information is shared. Firstly, the coordinate position of the vehicle or the mobile phone is positioned. Secondly, 3 minutes are needed for the front to reach the unobstructed road section (the speed of the time reaches 70 kilometers per hour), and when the timing needs 2 minutes to reach the unobstructed road section, the engine is started to run at an idle speed. The vehicle reaches a normal road section, and after the vehicle accelerates to 70 kilometers/hour, the vehicle is driven by the engine to run.

In summary, the user unlocks the door of the vehicle until entering the vehicle to start the engine, and a certain time interval exists in the process. And after the door of the vehicle is unlocked and opened, the oil pump of the engine is started to operate preferentially, and the engine oil in the oil pump supplies oil to and lubricates all parts of the engine of the vehicle. In this process, the spark plug and the carburetor of the engine do not operate, nor does the electronic control unit perform the engine ignition operation. When the user sits in the vehicle and closes the vehicle door, the safety belt is tied, and the engine is started, engine oil is sprayed on the inner surface of the cylinder wall of the engine cylinder, and then the engine oil is coated by the piston in a scraping mode in a vertical running mode to form a layer of oil film. Therefore, the effect of lubricating the engine before starting is achieved, the problem that the inner surface of the cylinder wall of the cylinder lacks engine oil after the engine is parked for a long time is reduced or solved, and abrasion of the engine during starting is reduced.

And (4) starting the engine by the method of the S101-S103, and providing running power for the vehicle by the engine. And the starting motor supplies the engine oil to each part of the engine for lubrication in a short time by transferring the engine oil pump at a high speed. The time duration is less than the time taken for the user to open the vehicle door lock until the user enters the vehicle to start the engine. The shorter this time, the better, and the best is less than 7 seconds. The hybrid vehicle may start the engine by the method of S101-S103, and the hybrid vehicle may run by driving the vehicle by the driving motor at a low speed.

And the running vehicle automatically starts the idling of the engine when the engine stop running time is longer than the maximum time interval set by a timer. The engine needs to reach a set temperature or a set idle running time before the engine is started to drive the vehicle to run forwards. And after the engine runs at an idle speed, if the engine running requirement is not met, stopping the engine. Specifically, in the hybrid vehicle type, when the engine is not started for a long time while the vehicle is running.

1. During the running of the vehicle;

2. recording the time when the engine stops running, starting timing, recording the time when the engine runs for the last time if the engine runs again within the specified time, and timing again;

3. if the engine is not started within a prescribed time, the following method is performed:

1) and starting the starting motor or the driving motor to drive the engine to operate through the crankshaft. And after the starting motor operates for a set time, the starting motor stops rotating to provide conditions for low-abrasion starting of the engine.

2) Or after the starting motor runs, starting the engine to run at an idle speed.

3) And directly starting the engine to run at an idle speed.

The method comprises the following modes in the process of switching the starting motor to start the engine.

1. After the starting motor drives the oil pump to run at a high speed, the engine oil is quickly conveyed to the surfaces of all parts of the engine for lubrication. And then, the starting motor is powered off and stops working. When the starting motor stops rotating, the engine piston also stops rotating. The user initiates the engine ignition operation in the vehicle. This includes two ways: firstly, the vehicle door is unlocked, the generator is started to run at a high speed, and oil supply and lubrication to each part are completed in a short time. The starter motor has enough time to decelerate and stop running before the user starts the engine, and then the starter motor is recovered to be in a static state.

Secondly, when the user quickly enters the vehicle and starts the engine to ignite and run, the starting motor does not completely stop rotating, and the starting button or key of the engine starts the engine in a delayed mode.

2. When the starting motor is electrified to operate, the vehicle electric control device monitors the motion condition of the piston in real time. Starting the engine when the starter motor has not completely stopped rotating. At the moment, the electric control device in the vehicle acquires a starting instruction pressed by the engine starting button or a key ignition starting instruction, and the electric control device normally ignites to start the engine to run according to the running condition of the engine piston monitored in real time.

As shown in fig. 2, fig. 2 is a schematic structural diagram of the engine-started dual oil pump provided by the present application.

Specifically, the method for starting the engine when the engine of the vehicle comprises two oil pumps.

1. The user unlocks the doors of the vehicle outside of the vehicle.

2. And receiving the door unlocking instruction, and starting an oil supply motor by the vehicle electric control device to drive the first oil pump to run so as to supply engine oil lubrication for each part of the engine.

3. When the user enters the vehicle, the engine is started through a start button or a key, and the engine supplies oil and operates in an ignition mode. At the moment, the engine camshaft drives the second oil pump to run and supply oil, and oil lubrication is supplied to each part in the engine. And meanwhile, the oil supply motor and the first oil pump gradually stop working.

Furthermore, the oil pump of the engine consists of a first oil pump and a second oil pump, and the first oil pump and the second oil pump share a set of oil passage and a set of nozzle. The oil is fed through the oil inlet manifold and discharged through the oil outlet manifold. Wherein, the first oil pump is driven by the oil supply motor to operate. And engine oil enters the first oil inlet channel from the main oil channel of the oil inlet manifold, flows into the first engine oil pump and flows out of the first oil outlet channel into the main oil channel of the oil outlet manifold. After the engine is started, the second oil pump drives a camshaft by the engine gear shaft, and the camshaft drives the second oil pump to operate. And engine oil enters a second oil inlet channel from the main oil channel of the oil inlet manifold, flows into the second engine oil pump, and flows out of the second oil outlet channel into the main oil channel of the oil outlet manifold. The first oil pump starts to work before the second oil pump, and when the engine is ignited and started, the second oil pump starts to work, and the first oil pump gradually stops working. The first oil supply pump is driven by an independent oil supply motor to operate, the oil supply motor is powered by the vehicle storage battery or the battery pack to operate, and the camshaft of the engine drives the second oil supply pump to operate. Wherein the first oil pump is operated only before the engine of the vehicle is started. The first oil pump and the second oil pump are arranged in parallel and are respectively and independently supplied with oil, but the first oil pump and the second oil pump use the same oil duct to transfer and convey the engine oil and spray the engine oil.

As shown in fig. 3, fig. 3 is a schematic structural diagram of the engine pump driven by the engine-started hybrid vehicle provided by the present application.

Specifically, the oil pump is driven to operate by a driving motor in the hybrid vehicle.

1. And unlocking the vehicle door when the vehicle is the hybrid vehicle.

2. The electric control device starts a driving motor, the driving motor drives an engine to rotate and drives the oil pump to operate; or the driving motor directly drives the oil pump to operate.

3. And when the vehicle runs for a set time, the driving motor drives the vehicle to move forwards. Meanwhile, a driving gear of the driving motor is separated from the transmission gear of the engine or the oil pump.

Further, when the vehicle is a power unit for running of the vehicle, which is formed by the engine and the driving motor together, the driving motor drives the vehicle to run at a low speed. Meanwhile, when the vehicle is started or the engine is not started within a specified time, the driving motor drives the vehicle to move forward and also drives a gear shaft of the engine to rotate, the gear shaft drives a cam shaft of the engine to rotate, and the cam shaft drives the oil pump to operate so as to supply oil for lubricating various components of the engine. The piston moves up and down to uniformly scrape the engine oil sprayed to the inner surface of the cylinder wall of the cylinder by the engine oil pump through the oil scraper ring. During this process, the engine is not operated with ignition. After the starting motor operates for a set time, the driving gear of the driving motor is separated from the transmission gear on the gear shaft of the engine, and the driving motor only provides power for the low-speed running of the vehicle. When the engine is required to be used, the engine is operated by direct ignition.

Or the driving motor directly drives a transmission gear of the oil pump to rotate through the driving gear, and the oil pump lubricates all parts of the engine with engine oil. After the starting motor operates for a specified time, the driving gear is separated from a transmission gear on the oil pump, and the driving motor only provides power for the low-speed running of the vehicle. When the engine is required to be used, the engine is operated by direct ignition.

Of course, in the hybrid vehicle, the oil pump may be driven by the starter motor in the engine to supply oil. And the driving motor is only responsible for driving the vehicle to run.

As shown in fig. 4, fig. 4 is a schematic structural diagram of the vehicle kinetic energy recovery when the engine is started.

Specifically, in the running process of the vehicle, energy is automatically recovered and braked by combining a kinetic energy recovery device according to distance measuring equipment installed in the vehicle.

1. During the running process of the vehicle;

2. and according to the vehicle distance measurement result, combining the vehicle running speed, automatically entering a kinetic energy recovery state, and stopping the power output of the engine and the driving motor of the vehicle.

Further, when the kinetic energy recovery device is installed in the vehicle, the distance between the vehicle and the vehicle or the pedestrian or the object or the building in front is measured by the vehicle through a laser range finder or an infrared range finder. And meanwhile, acquiring data of the real-time running speed of the vehicle. And then according to the standard values of the safe braking distance of the vehicle at different speeds. And once the vehicle is at the current running speed and the distance between the vehicle and the front vehicle or the object or the building is closer and closer, the vehicle automatically starts a kinetic energy recovery device to recover kinetic energy and generate power within the range of the reasonable braking distance. The electric quantity generated by recovering the kinetic energy is stored in a storage battery of the vehicle or a battery pack of the vehicle to charge the storage battery or the battery pack of the vehicle. Meanwhile, in the kinetic energy recovery process, the vehicle is decelerated, and before the vehicle collides, the vehicle is decelerated to a stop state, so that the vehicle is prevented from rear-end collision or collision.

And when the distance of the distance measurement result is gradually increased from near to far, simultaneously, the user steps on an accelerator or a switch to drive the vehicle to move forward. At this time, the recovery of kinetic energy is stopped, and the vehicle is driven to accelerate forward by the engine or the drive motor.

The kinetic energy recovery device is used for recovering kinetic energy by matching an independent generator and a battery pack with an electric control device and the vehicle distance measuring sensor device. Further comprising: the kinetic energy recovery device is used for recovering kinetic energy by matching a driving motor and a battery pack in the hybrid vehicle with an electric control device and the vehicle distance measuring sensor device. Wherein the drive motor is used as a traction motor for providing traction for the vehicle. And can also be used as a generator for recovering kinetic energy. The vehicle distance measuring sensor device has the function of braking through kinetic energy recovery, and can also prompt a user to manually step on the brake or execute automatic braking, so that rear-end accidents are prevented.

The battery heat is thermally conductive to provide heat to the engine through the temperature generated by the vehicle battery pack. So that the temperature in the cylinder body is certain.

The heating method comprises the following steps:

1. heating the intake manifold to reduce or eliminate water vapor;

2. the air is heated to expand, the air input is reduced when the vehicle runs at high speed, and the water vapor is reduced to enter the air cylinder.

In conclusion, when the engine runs at an idle speed, the storage battery or the battery pack is charged through the motor, meanwhile, the engine is preheated, and the engine is always in a good working stability and a good working state in the hybrid vehicle type. And the cylinder wall of the cylinder is lubricated by engine oil before starting by adding the engine oil pump.
