Abstract

The invention provides a vehicle speed control method, a system, a readable storage medium and an electric vehicle. Acquiring the current driving speed in real time, and judging whether the current driving speed meets the speed control condition; If so, according to the current traveling vehicle speed and the set speed, a control torque is generated and set to the motor to control the rotational speed of the motor to control the vehicle speed within the set speed. According to the speed control method of the present invention, while the vehicle is in motion, the set speed in the current driving mode is automatically obtained, When the current driving speed meets the speed control condition, the control torque is generated and set to the motor or the brake system according to the current driving speed and the set speed, so as to reduce the motor speed or the brake, thus avoiding the overspeed driving, improving the battery endurance and the service life of the hardware equipment.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle speed control method, system, readable storage medium and electric vehicles. Background technique [0002] Electric vehicles (Blade Electric Vehicles, referred to as BEV) refer to vehicles that use on-board batteries as power sources and drive wheels with motors. Compared with fuel vehicles, they have the advantages of low emissions, energy saving, environmental protection, low noise, and low cost. The sales volume of green vehicles advocated by contemporary is also increasing year by year. [0003] Among the existing technologies, the current electric vehicle lacks the speed limit technology, which leads to the possibility of overspeeding in any driving mode of the electric vehicle, and the speeding of the electric vehicle will accelerate the loss of power, shorten the mileage of the electric vehicle, and at the same time reduce the hardware The service life...
