Abstract

The invention provides a torque control method and device, and a vehicle. The torque control method includes the following steps: clutch oil filling pressure and throttle opening of the vehicle are detected during a starting process of the vehicle; a slope of engine torque is obtained according to the clutch oil filling pressure and the throttle opening; wherein the slope of the engine torque is an increasing amount of the engine torque per unit time; and the torque of an engine is controlled according to the slope of the engine torque. The torque control method of the invention can achieve timely and smooth starting of the vehicle, and give a driver a good driving experience.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular to a torque control method, device and vehicle. Background technique [0002] With the continuous development of science and technology, vehicle technology has also developed rapidly, and driving a vehicle has become the primary choice of people. However, in the process of driving a vehicle, people may encounter the problems of delayed start and uneven start of the vehicle. [0003] For the above-mentioned problems of delayed start and uneven start of the vehicle, related technologies mainly control the start of the vehicle by controlling the clutch torque of the vehicle. However, the starting control is only carried out through the clutch torque of the vehicle. In the case of a small amount of oil in the clutch, due to the low oil pressure, the clutch is combined slowly, and the vehicle may not be able to start in time; In some cases, due to the excessive pressure of th...
