Technical Field

The present invention relates to the field of vehicle technologies, and in particular, to a control method of a vehicle, a control apparatus of a vehicle, an electronic device, and a computer-readable storage medium.

Background

The driving modes of the plug-in hybrid electric vehicle are mainly divided into: the electric vehicle comprises a pure electric vehicle, a parallel hybrid drive vehicle, a series hybrid drive vehicle and an engine drive vehicle. The other three modes except the first pure electric running mode in the above 4 running modes all need the participation of starting the engine. Therefore, the engine start-stop control strategy is a great important factor influencing the running energy consumption of the plug-in hybrid electric vehicle, and whether the engine start-stop control strategy is reasonable or not is directly related to the fuel consumption performance of the whole vehicle.

The engine start-stop control strategy of the current plug-in hybrid electric vehicle mainly comprises the following steps: 1. starting and stopping the vehicle, wherein when the speed of the whole vehicle exceeds a preset vehicle speed threshold value, an engine is started; 2. starting and stopping the power, wherein when the driving power or the driving required power of the whole vehicle exceeds a preset power threshold value, an engine is started; 3. and (4) torque starting and stopping, wherein when the torque required by the whole vehicle exceeds a preset torque threshold value, the engine is started.

However, the above engine start-stop strategies all have their corresponding limitations, where the vehicle speed start-stop only controls the engine start-stop from the perspective of the vehicle speed, and when the power demand is small, if the vehicle speed exceeds a preset vehicle speed threshold value, the engine is immediately started, and it cannot be guaranteed that the engine is in a high-efficiency working area after being started, and although the power demand is very small under a downhill working condition, the vehicle speed still triggers the engine start condition. Although the power start and stop can ensure that the engine is in a relatively efficient working area when being started, the working condition point of the engine is difficult to be limited in the efficient working area by a fixed power threshold value due to the fact that the fluctuation of the required power of an accelerator pedal is very large in the driving process, and the engine can be frequently started and stopped. The torque starting and stopping are similar to the power starting and stopping, the torque demand fluctuation in the driving process is very large, the single torque judgment condition cannot well limit the working condition point of the started engine in a high-efficiency working area, and frequent starting and stopping can be caused.

In summary, the engine start-stop strategy of the current plug-in hybrid electric vehicle cannot effectively concentrate the working condition points after the engine is started in the high-efficiency area, and the whole vehicle energy consumption has a large optimization space from the engine start-stop control perspective.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A control method of a vehicle, a control apparatus of a vehicle, an electronic device, and a computer-readable storage medium according to embodiments of the invention are described below with reference to the drawings.

The vehicle according to the embodiment of the invention is a plug-in hybrid vehicle.

Fig. 1 is a flowchart of a control method of a vehicle according to one embodiment of the invention. As shown in fig. 1, the method comprises the steps of:

and S1, acquiring the speed of the vehicle, the output power of the motor and the output power of the engine.

And S2, controlling the start and stop of the engine according to the speed of the vehicle, the output power of the motor, the output power of the engine, the speed threshold value and the power threshold value of the start and stop of the engine.

Specifically, the power threshold for starting and stopping the engine is as follows: the method is characterized by referring to a starting and stopping power judgment point of an engine when pure electric drive is switched to hybrid drive, wherein the power point refers to real-time output power of a motor during driving. Speed threshold of engine start-stop: the vehicle speed point is a starting and stopping vehicle speed judging point of an engine when pure electric drive is switched to hybrid drive, and the vehicle speed point is the real-time speed of the whole vehicle.

The speed threshold and the power threshold of the engine start and stop can be preset by combining an engine fuel consumption rate graph and a running resistance power curve of the engine. The power threshold value of the engine starting and stopping is required to enable the engine to work in a high-efficiency area after being started as much as possible, and the specific power threshold value is different due to different engine power graphs. The speed threshold value of the engine needs to be set by comprehensively considering a constant speed running resistance power curve of a vehicle, the power demand is low at a low speed and the motor drive is prioritized, the power demand is high at a high speed and the power consumption is high, the pure electric drive energy consumption is quickly increased and is converted into the engine drive, and the motor drive is assisted.

The control method of the vehicle comprehensively considers the speed of the vehicle, the output power of the motor and the output power of the engine to control the starting and the stopping of the engine, so that the engine of the vehicle can work in a high-efficiency area with the maximum probability after being started, and the energy consumption of the vehicle is reduced.

How to control the start and stop of the engine according to the speed of the vehicle, the output power of the motor, the output power of the engine, the speed threshold value and the power threshold value of the start and stop of the engine is described below with reference to specific embodiments.

According to an embodiment of the present invention, as shown in fig. 2, the controlling the engine to start and stop according to the speed of the vehicle, the output power of the motor, the output power of the engine, the speed threshold and the power threshold of the engine to start and stop may include:

and S201, if the speed of the vehicle is greater than the speed threshold value for starting the engine and the output power of the motor of the vehicle is greater than the power threshold value for starting the engine, controlling the engine to start.

And S202, if the speed of the vehicle is equal to or less than the speed threshold value of the engine stop and the output power of the engine is equal to or less than the power threshold value of the engine stop, controlling the engine to stop.

Specifically, if the real-time vehicle speed is greater than the speed threshold value of the engine starting, and the real-time power of the motor is greater than the power threshold value of the engine starting, the engine is controlled to be started, and if the engine is started, the engine is kept in a starting state. And if the real-time vehicle speed is equal to or less than the speed threshold value for starting the engine, and the real-time power of the motor is equal to or less than the power threshold value for starting the engine, controlling the engine to stop, and if the engine is in the stop state, keeping the engine in the stop state.

According to an embodiment of the present invention, as shown in fig. 3, the control method of the vehicle described above may further include:

and S101, acquiring the residual capacity of the power battery.

The remaining capacity is SOC (State Of Charge).

And S102, determining a speed threshold and a power threshold of starting and stopping the engine according to the residual electric quantity.

Further, determining a speed threshold and a power threshold of starting and stopping the engine according to the remaining capacity includes: determining a preset remaining power range interval to which the remaining power belongs; and determining the speed threshold and the power threshold of starting and stopping the engine according to the residual electric quantity and the range interval of the residual electric quantity.

In one embodiment of the present invention, the remaining capacity range section includes: the low remaining capacity range interval, the middle remaining capacity range interval and the high remaining capacity range interval determine the preset remaining capacity range interval to which the remaining capacity belongs, and the method comprises the following steps: if the residual electric quantity is smaller than a preset first residual electric quantity threshold value, determining that a residual electric quantity range interval to which the residual electric quantity belongs is a low residual electric quantity range interval; if the residual electric quantity is equal to or larger than the first residual electric quantity threshold value and smaller than a preset second residual electric quantity threshold value, determining that a residual electric quantity range interval to which the residual electric quantity belongs is a middle residual electric quantity range interval; and if the residual capacity is equal to or larger than the second residual capacity threshold value, determining that the residual capacity range interval to which the residual capacity belongs is a high residual capacity range interval.

The first remaining capacity threshold and the second remaining capacity threshold may be preset according to an actual situation, for example, the first remaining capacity threshold may be 15%, and the second remaining capacity threshold may be 55%. That is, if the remaining capacity is less than 15%, determining that the remaining capacity range section to which the remaining capacity belongs is a low remaining capacity range section; if the residual capacity is more than or equal to 15% and less than 55%, determining that the residual capacity range interval to which the residual capacity belongs is a middle residual capacity range interval; and if the residual capacity is larger than or equal to 55%, determining that the residual capacity range interval to which the residual capacity belongs is a high residual capacity range interval.

Specifically, the speed threshold and the power threshold of the start and stop of the engine corresponding to the remaining power range may be preset in combination with an engine fuel consumption map and a driving resistance power curve of the engine. The engine starting and stopping power threshold value needs to comprehensively consider an engine efficiency map of a vehicle, the engine starting and stopping power threshold value needs to enable the engine to work in a high-efficiency area after being started as much as possible, the specific power threshold value is different due to different engine power maps, the working condition point of the engine is strictly limited in the high-efficiency area by the power threshold value when the SOC is high, and the power limitation needs to be relaxed due to the power generation requirement of the low SOC. The speed threshold value of the engine needs to be set by comprehensively considering a constant speed running resistance power curve of a vehicle, the power demand is low at a low speed and the motor drive is prioritized, the power demand is high at a high speed and the power consumption is high, the pure electric drive energy consumption is quickly increased and is converted into the engine drive, and the motor drive is assisted. The speed threshold of each specific SOC engine is different according to the resistance power curve of the vehicle.

During the running process of the vehicle, a speed threshold and a power threshold of starting and stopping the engine are determined according to the range of the residual electric quantity and the residual electric quantity, and the starting and stopping of the engine are controlled according to the speed threshold and the power threshold of starting and stopping the engine, so that the engine of the vehicle can work in an efficient area with the maximum probability after being started, and the energy consumption of the vehicle is reduced.

The following describes how to determine the speed threshold and the power threshold of the engine start-stop according to the remaining capacity and the remaining capacity range section in detail with reference to the drawings.

FIG. 4 is a graph of remaining battery charge versus power threshold for engine start-stop according to one example embodiment of the present disclosure.

FIG. 5 is a graph of remaining battery charge versus engine start-stop speed threshold according to one specific example of the present disclosure.

It should be noted that, in the embodiment of the present invention, determining the speed threshold and the power threshold of the engine start-stop according to the remaining capacity and the remaining capacity range interval may include: if the remaining capacity range interval is the low remaining capacity range interval, it is determined that the speed threshold and the power threshold for starting the engine are both 0 (not specifically shown in fig. 4 and 5).

That is, if the remaining capacity of the power battery is less than 15%, the power battery is not charged enough, and the engine is controlled to be started all the time.

According to an embodiment of the present invention, as shown in fig. 4 and 5, if the remaining power range section is the middle remaining power range section or the high remaining power range section, the power threshold value of the engine start corresponding to the remaining power is greater than the power threshold value of the engine stop, the speed threshold value of the engine start corresponding to the remaining power is greater than the speed threshold value of the engine stop, and both the power threshold value and the speed threshold value of the engine start and stop corresponding to the remaining power increase with the increase of the remaining power.

As shown in fig. 4, the rate of change of the power threshold of the engine start/stop with the remaining power in the middle remaining power range interval is smaller than the rate of change of the power threshold of the engine start/stop with the remaining power in the high remaining power range interval. As shown in fig. 5, the rate of change of the speed threshold of starting and stopping the engine in the middle remaining power range interval with the remaining power is equal to the rate of change of the speed threshold of starting and stopping the engine in the high remaining power range interval with the remaining power.

Specifically, a curve of the power threshold value and the remaining capacity of the engine start and stop can be shown with reference to fig. 4; the speed threshold remaining charge for engine start-stop may be plotted as shown in fig. 5. The curves of different vehicles may be different, but the specific change of the curves needs to meet the requirements, and the curves of the power threshold value and the residual capacity of the engine start and stop, and the curves of the speed threshold value and the residual capacity of the engine start and stop can be preset in advance and stored.

According to an embodiment of the present invention, the control method of a vehicle described above may further include:

and if the remaining capacity range interval is a high remaining capacity range interval, controlling the engine as a main driving source and the motor as an auxiliary driving source after the engine is started, and driving the vehicle to run. And if the remaining power range interval is the middle remaining power range interval, controlling the engine to drive the vehicle to run and driving the motor to generate power after the engine is started.

If the remaining power range interval is a low remaining power range interval and the speed of the vehicle is less than the set speed, controlling the engine to drive the motor to generate power to drive the motor to drive the vehicle to run after the engine is started; and if the residual electric quantity range interval is a low residual electric quantity range interval and the speed of the vehicle is equal to or greater than the set speed, controlling the engine to drive the vehicle to run and driving the motor to generate power after the engine is started. The set speed may be set according to actual conditions, for example.

Specifically, the remaining power range is a high remaining power range, for example, the remaining power is higher than 55%, pure electric drive is maintained as much as possible, when the real-time speed of the vehicle is greater than a speed threshold value of engine start corresponding to the current remaining power, and the real-time power of the motor is greater than a power threshold value of engine start corresponding to the current remaining power, the engine is started, the motor serves as a main driving source and is converted into the motor serving as a main driving source, and the engine operates in a high-efficiency area.

If the remaining power range interval is a middle remaining power range interval, for example, the remaining power is in a 15% -55% interval, if the real-time speed of the vehicle is greater than the speed threshold value of the corresponding engine starting under the current remaining power, and the real-time power of the motor is greater than the power threshold value of the corresponding engine starting under the current remaining power, the engine is started, the engine drives the vehicle to run, and because the whole vehicle has a certain power-preserving target requirement, the engine drives the motor to generate power at the same time, so that the working point of the engine is pulled to the efficient working area.

If the remaining power range is a low remaining power range, for example, the remaining power is less than 15%, and due to the requirement of power leveling, if the speed of the vehicle is less than a set speed, the vehicle enters a series driving mode, an engine drives a BSG (Belt-Driven Starter Generator) motor to generate power, and the driving motor is used as a power source of the whole vehicle to drive the whole vehicle to run, so that a better working area of the engine is ensured; and if the speed of the vehicle is greater than or equal to the set speed, fuel oil driving and running power generation are carried out, namely the engine drives the vehicle to run and simultaneously drives the motor to generate power, and the working point of the engine is pulled to the efficient working area.

It is understood that the motor in the embodiment of the present invention may operate in a power generation mode or a driving mode, which is determined according to the specific operation condition of the vehicle.

The speed threshold and the power threshold of the starting and stopping of the engine are dynamically adjusted along with the residual electric quantity of the power battery, and the starting and stopping judgment conditions of the engine are different under different residual electric quantity conditions. The starting condition of the engine is severer when the residual electric quantity is high, the electric quantity of the power battery is preferentially used in the low-speed and small-load states, the engine is started when the residual electric quantity is high, the engine preferentially works in the optimal efficiency area at the moment, and the motor is responsible for compensating the torque of the part exceeding the optimal efficiency area of the engine. And when the residual electric quantity is medium, the starting and stopping conditions of the engine are reduced, and the working point of the engine is lifted or limited in a high-efficiency area through additional driving power generation of the engine. Therefore, the invention can limit the engine operating point in a high-efficiency area in the range of all the remaining electric quantity, and reduce the running energy consumption of the plug-in hybrid power by reasonably utilizing the electric quantity of the power battery.

In summary, according to the control method of the vehicle in the embodiment of the invention, the start and stop of the engine are controlled by comprehensively considering the speed of the vehicle, the output power of the motor, the output power of the engine and the residual capacity, so that the engine of the vehicle can work in the high efficiency area with the maximum probability after being started, and the energy consumption of the vehicle is reduced.
