[0003] The braking system of the vehicle in the prior art includes brake braking, manual braking, etc. In the traditional situation, when the driver encounters an emergency, he usually releases his right foot stepping on the accelerator quickly, and moves to the brake pedal at the same time. , and depress the brake pedal. When the brake pedal is depressed, the speed of the vehicle will decrease. The driver can respond in time when an emergency situation is discovered, and there is a possibility of delaying the operation, which poses a great threat to the driving safety of the vehicle

The invention discloses a braking control method for a light electric vehicle. The braking control method comprises steps as follows: acquiring the current vehicle speed and the opening degree of an accelerator pedal of the vehicle; judging whether the vehicle speed exceeds a preset accelerator braking vehicle speed, if yes, judging whether the opening degree of the accelerator pedal exceeds a preset accelerator braking opening degree, and if yes, acquiring the accelerated speed of the accelerator pedal during lifting, and performing the next step; judging whether the accelerated speed is higher than 80% of the accelerated speed of the accelerator pedal during unrestrained lifting, and if yes, sending a pre-braking signal to an electric braking device of the vehicle, wherein the pre-braking signal comprises the signal for controlling a motor controller through the electric braking device to supply power to an electric motor to control the electric motor to brake. The pre-braking operation can be performed earlier than the braking operation of the braking pedal, and misjudgment of a driver on braking operation can be avoided. The invention further discloses a braking control system used for the light electric vehicle and adopting the method.
Description
technical field [0001] The invention relates to the technical field of vehicle control, and more specifically, to a braking control method for a light electric vehicle. In addition, the present invention also relates to a system for implementing the above light electric vehicle braking control method. Background technique [0002] The braking system of the vehicle is one of the important control systems of the vehicle, and the development of vehicle control braking technology determines the technical level of the vehicle. [0003] The braking system of the vehicle in the prior art includes brake braking, manual braking, etc. In the traditional situation, when the driver encounters an emergency, he usually releases his right foot stepping on the accelerator quickly, and moves to the brake pedal at the same time. , and depress the brake pedal. When the brake pedal is depressed, the speed of the vehicle will decrease. The driver can respond in time when an emergency situation...
