A vehicle torque control method, device, control equipment and vehicle

Abstract

The invention provides a vehicle torque control method, device, control equipment and vehicle. The control method includes: when receiving a request to enter a low-speed working mode, judging whether the vehicle currently meets the conditions for entering the low-speed working mode; When the condition of the working mode is met, control the vehicle to enter the low-speed working mode, and monitor the accelerator pedal opening and vehicle speed; if the accelerator pedal opening is 0, and the current vehicle speed is greater than zero and less than or equal to the first preset speed value, then control The vehicle enters PI control with a target speed of 0 rpm, determines the target torque of the motor according to the PI control, controls the drive motor to work according to the target torque, and continues to monitor the opening of the accelerator pedal; and, when the opening of the accelerator pedal is greater than the first preset When the opening value or the vehicle speed is greater than the second preset speed value, the vehicle is controlled to exit the PI control. In the low-speed working condition, the vehicle can be accelerated and decelerated to follow the preceding vehicle only by stepping on the accelerator pedal, thereby reducing driving fatigue.

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...
