Problems solved by technology

[0003] During the driving process of the vehicle, due to various factors such as steering requirements, uneven road surface, inconsistent tire pressure, load change, different degree of tire wear, manufacturing errors, etc., the length of the driving path of the wheels on both sides will be different. Different coefficients are prone to tire slippage, which affects the driving safety of the vehicle and increases the probability of safety accidents

Abstract

The embodiment of the invention discloses a vehicle control method and device. The control method of the vehicle comprises the steps that according to each criterion in at least two criteria, whether wheels of the vehicle slip or not is judged; and according to the judgment results of the at least two criteria, the torque of the wheels of the vehicle is adjusted. According to the technical scheme provided by the embodiment of the invention, whether the vehicle slips or not can be accurately judged so as to find that the wheels of the vehicle slip in time, and the torque is adjusted to prevent the wheels from further slipping.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a control method and device for a vehicle. Background technique [0002] Energy saving, environmental protection and safety have become the themes of modern automobile development. In order to solve the energy crisis and environmental pollution caused by the increase in automobile ownership, the research and development of new energy vehicles has become one of the focuses of research in various countries. Pure electric vehicles are all powered by electric motors. Because of their zero emissions, simple structure, high efficiency, and relatively mature technology, they have become an important development form of new energy vehicles. If the electric vehicle adopts four-wheel independent drive, not only the mechanical transmission device required by the traditional vehicle can be omitted, the structure of the drive system and the whole vehicle can be simple and compact, th...
