Vehicle torque control method, device and equipment

Abstract

The vehicle torque control method, device and equipment provided by the present invention determine that the driving state of the vehicle is a reverse state; obtain the vehicle weight-to-load ratio, and the vehicle weight-to-load ratio is the ratio of the actual gross weight of the vehicle to the permitted gross weight of the vehicle; The corrected torque is determined according to the vehicle weight-to-load ratio and the vehicle's engine torque at the current moment; the vehicle's engine torque is controlled according to the corrected torque, so that when the vehicle is reversed, the vehicle is limited according to the real-time collected vehicle weight-to-load ratio The torque reduces the risk of the vehicle rushing out of the barrier caused by excessive output torque when it encounters the barrier when it is reversed, and improves the safety of the vehicle when it is reversed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle torque control method, device and equipment. Background technique [0002] In the unloading area of ​​the mining area, a retaining wall is often used to block the unloading vehicle to prevent the vehicle from reversing and overturning when unloading, which may cause a vehicle rollover accident. [0003] However, when the driving vehicle in the mining area is reversing, the engine often runs in a high-speed range. When the vehicle reversing encounters a retaining wall, the vehicle speed suddenly decreases, the engine speed decreases, and the output torque of the engine suddenly increases. If the output torque of the engine is not correct If the restriction is carried out, the vehicle is likely to rush over the retaining wall, and even cause a car crash. That is to say, there is a safety problem when the vehicle is reversing. [0004] Therefore, there is an urgent ne...

Problems solved by technology

[0003] However, when the driving vehicle in the mining area is reversing, the engine often runs at a high speed range. When the vehicle reversing and encounters a retaining wall, the vehicle speed suddenly decreases, the engine speed decreases, and the output torque of the engine suddenly increases. If the output torque of the engine is not correct If the restriction is imposed, the vehicle is likely to rush over the retaining wall, and even cause a car crash. That is to say, there is a safety problem when the vehicle is reversing.
