Abstract

The invention provides an automobile torque control method and device, control equipment and an automobile. The control method comprises the steps that when a request for entering a low-speed workingcondition mode is received, whether the automobile currently meets the condition for entering the low-speed working condition mode is judged; when the condition of entering the low-speed working condition mode is met, the vehicle is controlled to enter the low-speed working condition mode, and the accelerator pedal opening degree and the vehicle speed are monitored; if the accelerator pedal opening degree is 0 and the current vehicle speed is larger than zero and smaller than or equal to a first preset speed value, the vehicle is controlled to enter PI control with the target rotating speed being 0 r / min, the target torque of a motor is determined according to the PI control, a driving motor is controlled to work according to the target torque, and the accelerator pedal opening degree continues to be monitored; and when the accelerator pedal opening degree is larger than the first preset opening degree value or the vehicle speed is larger than the second preset speed value, the vehicleis controlled to quit PI control. Under the low-speed working condition, the vehicle can be accelerated and decelerated to follow the front vehicle only by stepping on the accelerator pedal, and driving fatigue is reduced.

Description

technical field

[0001] The invention relates to the field of automobiles, in particular to an automobile torque control method, device, control equipment and automobile. Background technique

[0002] With the development of society, private cars are increasing year by year, and traffic jams have become a problem that cannot be ignored in modern life, especially in big cities. In congested road sections, when the vehicle is running at low speed, the driver needs to step on the accelerator pedal and brake pedal frequently, and follow the vehicle in front through electric drive and mechanical brake.

[0003] Normally, the one-pedal function enables energy recuperation by releasing the accelerator pedal when the vehicle is traveling at high speeds. Considering the driving comfort, the vehicle does not regenerate energy when the vehicle is at low speed. When the vehicle is in a congested condition, the speed is also low, so the vehicle does not perform energy recovery, resultin...
