Abstract

The invention provides a vehicle control method and device and a vehicle. The vehicle control method comprises the steps that whether the opening degree of an accelerator starts to be decreased or notis detected; and if yes, the torque of a generator is reduced. According to the vehicle control method and device and the vehicle provided by the embodiment of the invention, the state of the whole vehicle is smoother.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle control method, device and vehicle. Background technique [0002] At present, in order to better save energy and protect the environment, the development of electric vehicles has increasingly become the mainstream trend of the times. The drive system is one of the most important systems of electric vehicles. The operating status of the drive system directly affects the vehicle status . [0003] Because there is a gap in the drive system of the whole vehicle, when the accelerator is released, due to the reverse direction of the power, some impacts will occur on the components of the transmission system, making the state of the whole vehicle not smooth. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, the first object of the present inventi...
