Abstract

The invention provides a vehicle control method and device, control equipment and an automobile, and the vehicle control method comprises the steps: obtaining state parameter information of a current vehicle under the condition that the vehicle starts a rock driving mode; according to the state parameter information, whether the current driving state of the vehicle is abnormal or not is judged; and under the condition that the driving state is abnormal, according to the control strategy corresponding to the current vehicle speed, the distribution proportion between the first output torque of the first motor and the second output torque of the second motor is adjusted, and / or the suspension height of the vehicle is adjusted. According to the scheme, the escape ability of the vehicle in the rock terrain is enhanced, the passing performance of the vehicle is improved, and therefore the driving experience and safety of the vehicle are improved.

Description

technical field [0001] The present invention relates to the field of automobiles, in particular to a vehicle control method, device, control device and automobile. Background technique [0002] With the increasingly serious energy crisis and the continuous deterioration of the environment, new energy vehicles have received more and more attention and recognition. For new energy vehicles, the four-wheel drive layout is easier to achieve, and has the advantages of strong power and good control. Moreover, after good matching and calibration, the four-wheel drive model can achieve the same economic performance as the two-wheel drive model. Therefore, four-wheel drive vehicles have gradually become the future development trend of new energy vehicles. [0003] However, in the current new energy market, it is usually emphasized that new energy four-wheel drive vehicles should exert the advantages of power and maneuverability, and ensure the economy as much as possible within the ...
