Embodiment 1

[0033] This embodiment one discloses a warning system after an accident of a new energy EV vehicle, such as figure 1 As shown, the warning system includes: an airbag controller, a voltage and current sensor, a warning controller, a smoke warning generating device and an audio warning generating device.

[0034] The airbag controller is used to generate an airbag ignition signal or a high-voltage power-off signal, and send the signal to the warning controller when the vehicle has an accident and is triggered when the vehicle is seriously damaged or on fire;

[0035] The voltage and current sensor is installed on the vehicle body, and is used to detect the voltage and current value signals of the vehicle body in the accident after the vehicle has an accident and the warning system is started, and send the detected signal to the warning controller;

[0036] The warning controller receives the airbag detonation signal or the high-voltage power-off signal sent by the airbag control...

Embodiment 2

[0043] The first embodiment discloses a warning method after an accident of a new energy EV vehicle. The warning method is based on the warning system described in the first embodiment above, as follows: figure 2 As shown, the specific process of the warning method is as follows:

[0044] Step 1: The warning controller continues to receive the working status signal sent by the airbag controller, and receives the basic information of the vehicle operation;

[0045]Step 2: When the vehicle has an accident, the airbag controller generates an airbag ignition signal or a high-voltage power-off signal, and sends it to the warning controller, and the warning controller receives the airbag ignition signal or high-voltage After the power-off signal, it is judged that the vehicle has an accident at this time, causing serious damage to the vehicle or serious accident hazards such as fire, and activates the accident warning function;

[0046] Step 3: After starting the accident warning ...

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 ...
