Abstract

The embodiment of the invention discloses a power control method of an electric driving system, and relates to the technical field of electric automobiles. The method comprises the following steps: acquiring current driving road condition information of the electric vehicle; obtaining a target control mode corresponding to the current driving road condition information according to a pre-stored corresponding relation table of road conditions and control modes; the control module is related to output power control of an electric driving system of the electric automobile; and controlling the output power of an electric driving system of the electric vehicle in the target control mode. According to the invention, the corresponding appropriate output power of the electric driving system can be obtained according to the current driving road condition information of the electric automobile, and the automobile driving experience is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a power control method of an electric drive system. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. The emergence of electric vehicles has effectively reduced the emission of vehicle exhaust in the traditional energy-driven mode, making the automobile industry enter the field of environmentally friendly "new energy" from pure "energy saving". [0003] The power system of an electric vehicle is composed of a battery and an electric drive system. The output power of the electric drive system is a key factor that determines the power performance of an electric vehicle under different driving c...
