Abstract

The invention discloses a control method of a four-wheel-drive electric vehicle and a computer readable storage medium. According to the scheme, the method comprises the steps: determining the target demand torque of a vehicle according to the running state of the vehicle and the opening degree of an accelerator pedal; determining motor driving modes of the vehicle according to the target demand torque and the current vehicle speed of the vehicle, wherein the motor driving modes comprise a dual-motor driving mode and a single-motor driving mode; and according to the motor driving mode of the vehicle, distributing target demand torque to a front axle driving motor and a rear axle driving motor of the vehicle, wherein the front axle driving motor and the rear axle driving motor are permanent magnet synchronous motors. According to the control of the four-wheel-drive electric vehicle in the embodiment of the invention, the economical efficiency can be taken into account while the excellent dynamic property is embodied.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a control method and a computer-readable storage medium for a four-wheel drive electric vehicle. Background technique [0002] With the rapid development of science and technology, the control level of new energy vehicles is getting higher and higher. While the energy consumption of the whole vehicle is optimized, the driving range is greatly improved, which greatly alleviates the mileage anxiety of users, making new energy pure electric vehicles developed rapidly. With the popularity of electric vehicles, more and more users are beginning to pursue extreme acceleration. Four-wheel drive electric vehicles have better acceleration performance, but the efficiency of their drive motors is lower than that of two-wheel drive vehicles to a certain extent, resulting in an increase in energy consumption. [0003] In order to reduce the energy consumption of four-whee...
