Problems solved by technology

[0003] In a vehicle equipped with an electrical system, there are usually components that use high voltage and high current; for example, high voltage batteries, electric motors, and inverters; when the vehicle encounters an unexpected battery disconnection event, such as a vehicle crash, it may The high-voltage battery in the vehicle is disconnected from the load or system, which will generate residual voltage in the vehicle system, posing a threat to the driver's personal safety

Embodiment Construction

[0071] At present, in order to improve driving safety, a collision response system is usually installed in a vehicle. The collision response system is used to respond immediately and take some protective measures to protect the driver when a vehicle collision is detected.

[0072] In the related art, the above-mentioned crash response system can generally include seat belt pretensioners, airbags (including the driver's front, side, knee and curtain airbags), accelerometers (including lateral and longitudinal) and so-called restraint airbags. ECU (Electronic Control Unit, Electronic Control Unit) of the control module (RCM, Restrict Control Module).

[0073] During driving, the ECU of the above-mentioned restraint control module can read the accelerometer in real time, and judge whether the vehicle has collided according to the acceleration of the vehicle read (for example, it can be judged whether the variable of the vehicle acceleration within a unit time reaches the collisio...

Abstract

The invention provides a vehicle collision responding method applied to an electric or hybrid power vehicle. The method includes the steps that a potential collision target reported by vehicle-mounted radar and / or a vehicle-mounted camera and collision prejudgment information related to the potential collision target are obtained; based on the collision prejudgment information, whether the vehicle is about to collide with the potential collision target or not is prejudged; and if it is prejudged that the vehicle is about to collide with the potential collision target, the output current of a vehicle-mount power supply is reduced to a set safety value within preset time, wherein the preset time is shorter than collision remaining time. By the adoption of the method, the output current of the vehicle-mount power supply can be reduced to the set safety value in advance when it is prejudged that the vehicle is about to collide, and the traveling safety is improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method and system for responding to vehicle collisions. Background technique [0002] With the development of the automobile industry, electric vehicles have gradually begun to enter the lives of ordinary consumers. Due to the advantages of low cost, practicality and environmental protection of electric vehicles, the penetration rate of electric vehicles among ordinary consumers is also getting higher and higher. [0003] In a vehicle equipped with an electrical system, there are usually components that use high voltage and high current; for example, high voltage batteries, electric motors, and inverters; when the vehicle encounters an unexpected battery disconnection event, such as a vehicle crash, it may The high-voltage battery on the vehicle is disconnected from the load or system, which will generate residual voltage in the vehicle system, posing a threat to the driver's ...
