Abstract

The invention discloses a compensating method and device for vehicle torque and a vehicle so as to solve the problem that the compensation dosage of torque compensation on the vehicle is not accurateenough in the relevant technology. The method comprises the steps that speed information and driving torque information of the vehicle are collected; the variable quantity of road resistance torque iscalculated and obtained according to the speed information and driving torque information of the vehicle, wherein the variable quantity of the road resistance torque is the variable quantity of vehicle current road resistance torque relative to the road resistance torque of the vehicle running in the benchmark working condition; and torque compensation is conducted on the vehicle according to thevariable quantity of the road resistance torque.

Description

technical field [0001] The present disclosure relates to the field of vehicle engineering, in particular, to a vehicle torque compensation method, device and vehicle. Background technique [0002] When the vehicle is running on the road, it must overcome the air resistance and the rolling resistance of the road surface. When driving on the slope, it also needs to overcome the component force of gravity along the slope and the slope resistance. Among them, since both slope resistance and rolling resistance are related to road conditions, the two resistances are collectively referred to as road resistance. In pure electric vehicles, the torque of the vehicle is compensated according to the road resistance torque of the vehicle, so that the vehicle can obtain better power and economy, and the driver can obtain a better driving experience. [0003] The related technology can know the slope resistance of the current road by using GPS (Global Position System, Global Positioning S...
