Brake lamp control system and method for pure electric vehicle

Abstract

The invention discloses a brake lamp control system and method for a pure electric vehicle, and the method comprises the steps: controlling an energy recovery handle on the electric vehicle, and when the electric vehicle is in an OFF gear and a first gear, stepping on a brake pedal, and turning on the brake lamp; when the energy recovery handle on the electric vehicle is in the second gear, transmitting a signal to the brake lamp relay by the controller on the electric vehicle, electrifying the brake lamp relay, and lighting the brake lamp. According to the purpose, the brake lamp on the electric vehicle is divided into different working modes according to different gears of an energy recovery handle, the brake lamp is made to be in different working states in combination with actions of a brake pedal and an accelerator pedal on the electric vehicle, rear vehicles are reminded in time, and traffic safety accidents are avoided.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a brake light control system and method for a pure electric vehicle. Background technique [0002] On pure electric vehicles, there is usually an energy recovery handle. By adjusting the gear position of the energy recovery handle, partial recovery of energy can be realized, that is, the electric motor will generate electricity to charge the battery. During the energy recovery process, the electric vehicle will generally slow down. That is to say, a braking force will be generated to decelerate the electric vehicle; however, on a pure electric vehicle, in addition to the electrical braking force generated by the energy recovery of the motor, the braking system will also generate mechanical braking force, that is, the braking force is generated by stepping on the brake pedal, so that The vehicle slows down. [0003] On current electric vehicles, energy recovery (electric braking ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the electric braking force of the electric vehicle is not related to the brake light on the vehicle, when the electric vehicle is under electric braking, the vehicle behind cannot judge whether the vehicle in front is in a deceleration state according to the on / off of the brake light , and prone to traffic accidents, a brake light control system and method are proposed. The method associates the electric brake, accelerator pedal, and brake pedal with the brake light through the vehicle controller, and the brake The lights enter different working states according to different situations to ensure the stability and safety of vehicle operation
