Automobile fire alarm system and method

Abstract

The invention relates to an automobile fire alarm system and method. The system comprises one or more vehicle controller, a main fire controller, a fire sensor and an alarm, the vehicle controllers are connected by a CAN (controller area network) bus and comprise vehicle body controllers, seat controllers and engine controllers, and the main fire controller, the fire sensor and the alarm are connected with the vehicle body controllers through LIN (linear) buses. When a vehicle is in the case of fire, the main fire controller controls the alarm to give an alarm according to fire signals of thefire sensor and transmits the fire signals to the vehicle body controllers. After the vehicle body controllers acquire the fire signals, vehicle states are acquired from the engine controllers throughthe CAN bus. When the vehicle is static, vehicle release or / and unlocking is controlled according to signals of the seat controllers. When the vehicle runs, vehicle speed reduction is controlled by the engine controllers. By the system and the method, all-dimensional fire alarm is realized when the vehicle is in different states.
