Safe starting method and system based on electric vehicle

Abstract

The embodiment of the invention discloses a safe starting method based on an electric vehicle. A safe starting system of the electric vehicle comprises an alcohol detection module, a one-key startingmodule, a vehicle control unit, a gear controller, a brake pedal and a high-voltage module, wherein the safe starting method comprises the steps that vehicle door state information, brake pedal information and gear information of the electric vehicle are obtained; when the vehicle door state information, the brake pedal information and the gear information meet vehicle starting conditions, alcoholdetection is conducted through the alcohol detection module, and the first alcohol concentration in the electric vehicle is obtained; after the first alcohol concentration is smaller than a preset threshold value and the one-key starting module controls the vehicle control unit, the gear controller and the high-voltage module to pass self-inspection, the vehicle control unit controls the electricvehicle to be started; and when the first alcohol concentration is not smaller than the preset threshold value, the electric vehicle is forbidden to be started.

Description

technical field [0001] The embodiments of this specification relate to the technical field of vehicle safety, and in particular to a method and system for safe starting of an electric vehicle. Background technique [0002] With the progress of industry and the development of economy, electric vehicles have become an important tool for people to travel. However, while enjoying the convenience and speed brought by electric vehicles, people have to think about the potential hidden dangers of cars. Moreover, electric vehicles do not have an engine. As long as the ignition key is turned to the start gear, the vehicle can move forward when it is in gear, and it is easier to have an accident when starting. [0003] The prior art usually only checks seat belts and car doors before driving, and the electric car can be started after the seat belts and doors are checked, so that the cause of drunk driving will not be discovered until after an accident occurs, making the probability of...

However, while enjoying the convenience and speed brought by electric vehicles, people have to think about the potential hidden dangers of cars.

Moreover, electric vehicles do not have an engine, as long as the ignition key is turned to the start gear, the vehicle can move forward when it is in gear, and it is easier to have an accident when starting

[0003] The prior art usually only checks seat belts and car doors before driving. After the seat belts and doors are checked, the electric car can be started, so that the cause of drunk driving will not be discovered until after an accident occurs, making the probability of drunk driving accidents relatively low. high problem
