Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
An embodiment of the present invention provides a hybrid vehicle safety protection system, as shown in fig. 1, including: the system comprises a fuel subsystem 101, a high-voltage subsystem 102, a power battery device 103 and a vehicle control unit 104, wherein the fuel subsystem 101 comprises a fuel controller, a fuel pipeline and a fuel tank, the high-voltage subsystem 102 comprises a high-voltage part and a high-voltage controller, the power battery device 103 comprises a power battery controller and a power battery pack, the high-voltage subsystem 102 is connected with the fuel subsystem 101 and the power battery device 103, and the fuel subsystem 101, the high-voltage subsystem 102 and the power battery device 103 are all connected with the vehicle control unit 104.

Wherein the high voltage sub-system 102 comprises a high voltage controller and high voltage components, the high voltage components comprising: drive motor, generator, high voltage DCDC, etc.
The fuel subsystem 101 includes a fuel controller, fuel lines, and a fuel tank.
The power battery device 103 is connected with high-voltage components through a distribution box. Wherein, fuse and relay are arranged in the distribution box.
And when the vehicle control unit 104 receives the safety risk signal, the fuel subsystem, the high-voltage subsystem and the power battery device are controlled to execute respective corresponding safety protection actions.
Wherein, the safety protection action that this fuel subsystem 101 corresponds is as the fuel interruption action, includes: the fuel controller controls fuel in the fuel pipeline to be sucked back into the fuel tank; the corresponding safety protection action of the high-pressure subsystem 102 is a high-pressure relief action, and includes: the high-voltage controller controls the high voltage in the high-voltage component to be discharged below a safe voltage; the corresponding safety protection action of the power battery device 104 is a high voltage disconnection action, and includes: and the power battery controller controls and cuts off a high-voltage loop of the power battery pack and the high-voltage component.

According to the difference of the safety risk signals received by the vehicles, the situations of the vehicles are different, and when the safety risk signals received by the vehicles are collision signals, the corresponding vehicles collide. When the vehicle receives the safety risk signal as a maintenance signal, the corresponding vehicle is in the process of maintenance. When the vehicle receives a dangerous fault signal obtained by self-checking any one of the fuel subsystem, the high-voltage subsystem and the power battery device, the corresponding vehicle is in a static state or a running state.
In one embodiment, when the safety risk signal is a collision occurrence signal, the system further comprises:
the collision detection module 105 is used for detecting collision signals, and sending the collision signals to the fuel subsystem 101, the high-voltage subsystem 102, the power battery device 103 and the vehicle control unit 104 respectively; or the collision signal is sent to the vehicle control unit 104, the vehicle control unit 104 generates a safety protection instruction, and the safety protection instruction is respectively forwarded to the fuel subsystem 101, the high-voltage subsystem 102 and the power battery device 103.

The unsafe accident caused by the continuous work of the engine is avoided in a torque zero clearing mode; the vehicle is prevented from continuing to move forwards through emergency braking; people in the vehicle can escape in time by unlocking the vehicle door; by turning on the hazard lamps to alert surrounding personnel not to approach the vehicle.
In an embodiment, when the safety risk signal is a maintenance signal, the normal controller 104 receives the maintenance signal, generates a safety protection instruction, and sends the safety protection instruction to the fuel subsystem 101, the high-voltage subsystem 102, and the power battery device 103, respectively, so that the fuel subsystem 101, the high-voltage subsystem 102, and the power battery device 103 execute corresponding safety protection actions, respectively.

And when the safety risk signal is a dangerous fault signal obtained by self-checking any one of the fuel subsystem 101, the high-voltage subsystem 102 and the power battery device 103, the vehicle control unit 104 receives the dangerous fault signal and executes an alarm instruction to remind a driver of getting away from the vehicle. The personal safety of the driver is guaranteed through the alarm instruction executed by the vehicle control unit 104.
By adopting any one of the safety protection modes, the leak of single system safety protection is avoided, and the fuel safety, the high-voltage safety, the power battery safety and the whole vehicle safety of the hybrid vehicle are guaranteed.
