Vehicle torque control method, device and equipment

Abstract

The invention provides a vehicle torque control method, device and equipment. The method comprises the steps that the driving state of a vehicle is determined to be a backward state; a vehicle weightload ratio is obtained, wherein the vehicle weight load ratio is a ratio of the actual total weight of the vehicle to the permitted total weight of the vehicle; a corrected torque is determined according to the vehicle weight load ratio and the torque of an engine of the vehicle at the current moment; and the engine torque of the vehicle is controlled according to the corrected torque, so that when the vehicle retreats, the torque of the vehicle is limited according to the vehicle weight-load ratio collected in real time, the risk that the vehicle rushes out of a retaining wall due to the factthat the output torque of the retaining wall is too large when the vehicle retreats is reduced, and the safety of the vehicle during retreating is improved.

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.
