Abstract

The invention is applicable to the technical field of vehicle control, and discloses a four-wheel-drive vehicle control method and a terminal device. The method includes: acquiring road condition information at a preset distance in front of the four-wheel drive vehicle, operation information of the four-wheel drive vehicle, and data of the four-wheel drive vehicle. Demand torque value; calculate the front axle slip deviation value and rear axle slip deviation value of the four-wheel drive vehicle; determine the front axle slip deviation value according to the road condition information, operation information, required torque value, The target torque value of the axle motor and the target torque value of the rear axle motor; the four-wheel drive vehicle is controlled according to the target torque value of the front axle motor and the target torque value of the rear axle motor. The present invention can intervene in advance according to road condition information, four-wheel drive vehicle operation information and wheel slip conditions, and control the four-wheel drive vehicle according to the target torque value of the front axle motor and the target torque value of the rear axle motor, and can prevent from the power source. It can reduce the risk of vehicle loss of control and improve vehicle safety.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and in particular relates to a four-wheel drive vehicle control method and a terminal device. Background technique [0002] A four-wheel drive vehicle is simply a four-wheel drive vehicle with front and rear differential linkage. Four-wheel drive vehicles have superior off-road performance and are suitable for road conditions such as wild hillsides, tidal flats, muddy ground, and deserts. [0003] At present, when four-wheel-drive vehicles allocate four-wheel drive torque under special road conditions, they usually intervene after the stability control of the four-wheel-drive vehicle fails, which is an after-the-fact intervention. The intervention effect is not ideal, and the vehicle still has a greater risk of loss of control. , resulting in poor safety of four-wheel drive vehicles. SUMMARY OF THE INVENTION [0004] In view of this, the embodiments of the present invention provide a ...
