Embodiment 1

[0049] see figure 1 , shows the engine torque output control method in the first embodiment of the present invention, and the method includes steps S10-S13.

[0050] In step S10, during the starting process of the vehicle, the vehicle speed, the engine speed and the accelerator pedal opening of the vehicle are acquired in real time.

[0051] Wherein, in this embodiment, the starting process of the vehicle represents the time period from when the vehicle starts until the vehicle speed stabilizes to the preset vehicle speed range, for example, the vehicle speed stabilizes to 10km / h, and the vehicle speed, engine speed and accelerator pedal opening are within To a certain extent, it can represent the time node of the vehicle in the process of starting and driving. .

[0052] Step S11, respectively determining a first torque and a second torque for engine output according to the engine speed and the accelerator pedal opening.

[0053]Wherein, in this embodiment, two torque valu...

Embodiment 2

[0074] see figure 2 , shows the engine torque output control method in the second embodiment of the present invention, and the method includes steps S20-S25.

[0075] In step S20, during the starting process of the vehicle, the vehicle speed, the engine speed and the accelerator pedal opening of the vehicle are acquired in real time.

[0076] Step S21, respectively determining a first torque and a second torque for engine output according to the engine speed and the accelerator pedal opening.

[0077] Step S22, respectively determining the corresponding weights of the first torque and the second torque according to the vehicle speed.

[0078] Step S23, assigning and summing the first torque and the second torque through the weight, so as to control the engine to output torque.

[0079] In step S24, the transmission gear position of the vehicle is obtained, and the correction coefficient is determined according to the transmission gear position and the engine speed.

[0080...

Embodiment 3

[0091] see image 3 , shows the engine torque output control method proposed in the third embodiment of the present invention, and the method includes steps S30 to S35.

[0092] In step S30, during the starting and running of the vehicle, the vehicle speed, the engine speed and the accelerator pedal opening of the vehicle are acquired in real time.

[0093] Step S31, respectively determining a first torque and a second torque for the engine output according to the engine speed and the accelerator pedal opening.

[0094] Step S32, it is judged whether the time when the vehicle speed is lower than the preset vehicle speed satisfies the preset time range; if so, step S33 is executed.

[0095] Among them, the preset speed is the critical speed of the vehicle in a low-speed environment, such as 10km / h, 15km / h, which can be limited according to the actual situation. In practice, it is mainly determined by whether the vehicle is in a low-speed environment whether it is necessary to ...

Abstract

The invention discloses an engine torque output control method and system, a storage medium and a vehicle. The method comprises the steps that in the vehicle starting running process, the vehicle speed, the engine rotating speed and the accelerator pedal opening degree of the vehicle are obtained in real time; respectively determining a first torque and a second torque for engine output according to the engine rotating speed and the accelerator pedal opening degree; corresponding weights of the first torque and the second torque are determined according to the vehicle speed; and performing assignment summation on the first torque and the second torque through the weight so as to control the engine to perform torque output. The problem that in the prior art, when a vehicle is started and runs at a low speed, starting power is weak, and the driving feeling is affected is solved.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and in particular, to an engine torque output control method, system, storage medium and vehicle. Background technique [0002] With the development of society, automobiles have entered thousands of households and become an indispensable part of people's daily life. As people's needs change, automobiles need to meet people's needs in addition to the basic functions of their initial means of transportation. Comfort needs to enhance the user's driving experience. [0003] For example, when starting a vehicle, maintaining high torque at low speed can provide the driver with confidence to start, especially when starting a hill, high torque at low speed can provide the driver with confidence to start while allowing the vehicle to start smoothly. . [0004] In the prior art, in order to ensure the linear requirement of torque output during vehicle running, most vehicles will set a lower t...
