Electric vehicle safety starting method and system

Abstract

The invention discloses an electric vehicle safety starting method and a system. According to the conscious operation of an electric vehicle ignition key and the identification of an obvious optical signal hint by a driver, the safety staring process of the electric vehicle can be achieved. The safety starting system of the electric vehicle is correspondingly provided. The system comprises a CAN bus combination instrument, an integrated power supply, a battery management system, a high-voltage main positive contactor, an accelerator pedal, a motor controller, a state detector switch for a high-voltage device hatch, a whole vehicle control unit, a state detector switch for a charging hatch, an ignition key switch, a self-detecting indicator light and a READY indicator light. By adding operation logic of an ignition key START gear onto the starting process, and adopting a two-grade signal device which comprises the self-detecting indicator light and the READY indicator light, the driver can conveniently observe the starting state of the electric vehicle. Accordingly, the dangerous caused by unconscious vehicle staring of the driver can be avoided, and the starting safety of the electric vehicle can be improved.

Description

Technical field [0001] The invention relates to a safe starting method and system for a pure electric vehicle. Background technique [0002] Pure electric vehicles are hailed as the future development direction of automobiles because they do not use traditional energy, zero pollution and low noise. Pure electric vehicles do not have the engine of a traditional car, and there is no starter working process when starting. You only need to turn the ignition key to the ON position and the vehicle can enter the driving state when it is in gear. Such a pure electric vehicle starting system and starting method are prone to make mistakes. Drivers who are used to driving traditional vehicles will not realize that the vehicle can accelerate without turning the ignition key to START. When the ignition key is turned to ON and the shift panel is in D or R, the driver or other people in the car can’t hear the sound of the engine or feel the vibration of the car body and mistakenly step on the ...

AI Technical Summary

Problems solved by technology

Such a pure electric vehicle starting system and starting method are prone to misoperations, and drivers who are used to driving traditional vehicles will not realize that the vehicle can be accelerated without turning the ignition key to the START position.

When the ignition key is turned to the ON gear and the shift panel is in the D or R gear, the driver or other people in the vehicle cannot hear the sound of the engine or feel the vibration of the vehicle body, and when the accelerator pedal is stepped on by mistake, the vehicle will be damaged. Undesirable movement could result, which could result in more serious personal injury if there are people around the vehicle
