Detailed Description

To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. 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.

To facilitate understanding of the present application, the terms referred to in the present application are explained first:

electronic Control Unit (ECU): the computer is also called as a traveling computer or a vehicle-mounted computer and consists of a microprocessor (CPU), a memory (ROM and RAM), an input/output interface (I/O), an analog-to-digital converter (A/D), a shaping circuit, a driving circuit and other large-scale integrated circuits.

Diesel Particulate trap (DPF): the wall-flow filter is installed in an exhaust system of a diesel engine, can collect particulate emission substances before the particulate emission substances enter the atmosphere, mainly realizes the collection of particles by alternately plugging an inlet and an outlet of carrier pores and forcing airflow to pass through a porous wall surface, and has the PM filtering efficiency of more than 90 percent and up to 99 percent.

Diesel particulate trap regeneration (DPF regeneration): on the premise of the catalytic action of the catalyst, the process of oxidizing soot (soot) trapped on a diesel particulate filter is divided into active regeneration and passive regeneration.

Passive regeneration: nitrogen dioxide (NO) in waste when the temperature in the diesel particulate trap is greater than 250 ℃ under normal operating conditions₂) Oxidizing soot, i.e. NO₂+C＝CO₂+N₂To clean the soot in the diesel particulate trap.

Active regeneration: the method comprises the processes of driving regeneration and parking regeneration, wherein diesel oil is sprayed into exhaust to heat a diesel particulate filter or the diesel particulate filter is taken out and then heated so as to burn off soot.

And (3) traveling regeneration: and in the normal running process of the engine, the electronic control unit automatically judges conditions, and sprays diesel oil into the waste to further burn off the soot.

Parking regeneration: when the soot quality reaches the parking regeneration limit value, a user is required to stop the vehicle at a proper safety position, manually press a switch, execute the operation of spraying diesel oil in waste, and further burn off the soot.

Automatic Transmission (AMT): on the basis of a manual transmission, a set of electric control actuating mechanism is added to replace manual operation so as to realize the automatic gear shifting function. The actuating mechanism is divided into a gear selecting and shifting actuating mechanism and a clutch actuating mechanism.

In the background of the present application, the six engines in China are used to trap soot particles in exhaust gas by installing Diesel Particulate Filter (DPF) to meet the emission requirement. When the carbon loading capacity of the diesel particulate trap reaches a certain value, regeneration is needed, and carbon smoke particles in the diesel particulate trap are oxidized. The regeneration of the diesel particulate filter comprises active regeneration and passive regeneration, and the active regeneration comprises two modes of parking regeneration and driving regeneration.

On one hand, when the diesel particulate filter is in a running regeneration mode, the electronic control unit is required to control the opening of the air inlet throttle valve to achieve the purpose of improving the exhaust temperature, and then the purpose of entering a regeneration process is achieved. However, the intake throttle opening is reduced, and the intake air amount is reduced, resulting in a reduction in engine dynamics. On the other hand, when the exhaust temperature is lower, the engine enters a thermal management mode (SCR), and the purpose of thermal management is achieved by adjusting the opening of the air inlet throttle valve. However, similar to the diesel particulate filter driving regeneration mode, the decrease in the opening degree of the intake throttle valve and the decrease in the intake air amount may cause a decrease in the engine dynamic property.

In order to solve the problems, the application provides a method for controlling a throttle valve, an electronic control unit obtains an operation mode of an engine and sends the operation mode of the engine to an automatic gearbox control unit, and the automatic gearbox control unit performs gear shifting control and rotating speed correction control on the automatic gearbox when recognizing that the operation mode comprises a heat management mode or a diesel particulate filter driving regeneration mode, so that the engine operates in a large-load area, the exhaust temperature of the engine is improved, and the ending of the heat management mode or the diesel particulate filter driving regeneration mode is accelerated. When the electronic control unit acquires that the automatic gearbox control unit is in a gear shifting control mode, the electronic control unit corrects the opening size of an air inlet throttle valve of the engine according to the acquired accelerator pedal opening or accelerator pedal opening change rate, and the dynamic property of the engine is improved by temporarily increasing the opening of the air inlet throttle valve.

The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

and S101, acquiring an operation mode of the engine.

When the engine is started, the electronic control unit rapidly enters a working state, and real-time detection of each working condition state of the engine in the running process is completed. The operation modes comprise a thermal management mode, a diesel particulate filter driving regeneration mode and a normal mode. The heat management mode is also called an SCR (Selective Catalytic reduction) heating mode, and means that the temperature is controlled within an optimal temperature range, and nitrogen oxides are selectively reduced into nitrogen and water in an oxygen-rich environment under the action of a catalyst, so as to achieve the purpose of denitration and realize the treatment of tail gas. The normal mode refers to a state in which the engine is in normal running.

And S102, sending the running mode of the engine to an automatic gearbox control unit.

The electronic control unit, after acquiring the operation mode of the engine, transmits the operation mode of the engine to an automatic Transmission Control Unit (TCU). The automatic gearbox control unit is used for determining a gear shifting point when the automobile shifts gears, controlling the automobile gear shifting mechanism to perform gear returning and gear entering operations, calculating the motor rotating speed when the automobile shifts gears and calculating the automobile speed.

And S103, identifying the running mode by the automatic gearbox control unit.

The automatic gearbox can automatically perform automatic gear shifting operation according to the speed of the automobile and the rotating speed of an engine. The automatic gear shifting means that an accelerator pedal is controlled according to the requirement of a driving process in the driving process of the automobile, and an automatic gearbox automatically shifts to different gears to work according to the load of an engine and the running condition of the automobile.

Specifically, the electronic control unit obtains an opening degree of an accelerator pedal in a gear shifting process, and preferentially controls the intake throttle valve to be in a full-open state if the opening degree of the accelerator pedal is greater than a preset opening degree, wherein the preset opening degree can be 80% of the full-open opening degree of the accelerator pedal.

The electronic control unit monitors that the opening size of an air intake throttle valve of the engine can be corrected according to the opening change rate of an accelerator pedal when the automatic transmission control unit is in a gear-shifting control mode. Specifically, the average change rate of the opening degree of the accelerator pedal in the torque clearing and speed regulating stages in the gear shifting process is calculated, the opening size of the air inlet throttle valve is corrected according to the average change rate, the larger the average change rate is, the larger the opening of the air inlet throttle valve is, when the average change rate is larger than a preset change rate, the air inlet throttle valve is controlled to be in a full-open state, and the preset change rate can be 150/s, namely, the opening degree of the accelerator pedal changes by 15 degrees within 0.1 s.

The electronic control unit can compare the target gear sent by the automatic gearbox control unit in the period with the target gear sent by the jacket in the period, if the target gear and the target gear are not consistent, the automatic gearbox control unit is in a gear shifting control mode, and if the target gear and the target gear are consistent, the automatic gearbox control unit is not in the gear shifting control mode.
