Warning system and warning method for new energy EV vehicle after accident

Abstract

The invention discloses a warning system and a warning method for a new energy EV vehicle after an accident. The warning system comprises a warning system airbag controller, a voltage and current sensor, a warning controller, a smoke warning generation device and a sound warning generation device. According to the warning method, after it is judged that a serious traffic accident occurs accordingto the state signal sent by the safety airbag controller, the smoke warning generation device is controlled to emit a smoke warning signal outwards to prompt the position and type of an accident vehicle, and after the vehicle body voltage and current value detected by the voltage and current sensor exceeds a preset threshold value, the sound warning generation device is controlled to emit sound warning signals outwards to prompt that the electric leakage risk exists in the vehicle. After a new energy EV vehicle has a serious accident, an obvious warning signal can be sent to the surroundings,rescuers are reminded that the accident vehicle is an electric vehicle, the risk of electric shock exists in the rescue process is reminded, subsequent casualties are effectively reduced, and the rescue precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of post-accident safety warnings for new energy EV vehicles, and in particular relates to a post-accident warning system and method for new energy EV vehicles. Background technique [0002] With the promotion of my country's new energy strategy, the number of new energy EV vehicles has gradually increased. However, while vehicles bring us environmental protection, they also bring new safety challenges, that is, the problem of electric leakage after accidents. When a new energy EV vehicle is severely deformed in an accident, it may cause damage to high-voltage lines, high-voltage components or power batteries. The vehicle is not only prone to fire but also may have leakage. Personnel cannot identify the driving form of the vehicle, and there may be a risk of electric shock during the rescue process; in addition, electric vehicle fires require foam fire extinguishers. In many accidents, the type of vehicle on ...

Problems solved by technology

[0006] 3. The patented technical solution named "Vehicle Accident Notification System and Vehicle Accident Notification Method" is equipped with vehicle accident monitoring equipment. When an accident occurs, it can call a preset telephone number to inform the accident method and accident location. This technical solution Unable to issue anti-shock warning at the scene of the accident vehicle

[0007] In the above-mentioned existing technologies, the relevant technical solutions do not design relevant warning schemes for the particularity of new energy vehicles, and there is a lack of vehicle driving type prompts for on-site disposal personnel, or warnings of electric leakage hazards, and the rescue risk for on-site rescue personnel still exists.
