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.
本发明公开了一种新能源EV车辆事故后警示系统及警示方法,警示系统包括警示系统安全气囊控制器、电压电流传感器、警示控制器、烟雾警示发生装置和声音警示发生装置;警示方法根据安全气囊控制器发送的状态信号判断发生严重交通事故后,通过控制烟雾警示发生装置向外发射烟雾警示信号,提示事故车辆位置及车辆类型,通过电压电流传感器检测到的车身电压电流值超过预设阈值后,通过控制声音警示发生装置向外发射声音警示信号,提示车辆存在漏电风险。本发明能够在新能源EV车辆发生严重事故后,向周围发出明显警示信号,并提示救援人员事故车辆为电动汽车,提示救援过程中存在触电风险,有效减少后续伤亡提升救援的精准度及效率。
