The invention provides an airbag starting control method including the steps of detecting position of a driver by a first ultrasonic sensor arranged on a bridge in front of the driver and then outputting a first position signal, detecting the head height of the driver through a second ultrasonic sensor arranged on a roof above the driver and then outputting a second position signal, detecting position of a passenger on a passenger seat through a third ultrasonic sensor arranged on the bridge in front the passenger seat and then outputting a third position signal, converting the output signals of the first ultrasonic sensor, the second ultrasonic sensor and the third ultrasonic sensor into digital signals, and analyzing the signals of the sensors through internal programs of a controller to control start or stop of a first airbag, a second airbag and a third airbag according to the output signals of the sensors.
Description
technical field [0001] The invention relates to the field of vehicle electronics, in particular to a control method for starting an airbag. Background technique [0002] The development of automobiles not only has a huge effect on social economy, but also has an important impact on human life. Automobiles have become the main means of transportation for people to travel, and their convenience is unmatched by airplanes, ships and trains. [0003] As an emerging economy, China has become the world's largest automobile consumer. At present, the number of motor vehicles in my country has exceeded 100 million. There are more cars, roads are blocked, and traffic accidents are increasing. [0004] Accident studies have shown that airbags can greatly reduce the chances of drivers being injured, but due to the weak safety awareness of drivers and passengers, incorrect sitting postures when riding in the car will cause unnecessary injuries when the airbags are deployed.
