Vehicle sensor technology Among many car networking technologies, sensor technology is a very basic supporting technology. At the current stage, sensors and all aspects of the car, such as vehicle speed monitoring, temperature and humidity, brakes, fuel monitoring, etc., and In the future, as the degree of intelligence becomes higher and higher, the number and types of sensors used in cars will also increase even more. In the Internet of Vehicles, the main sensors involved are: car running monitoring sensors In the current car, there are already a variety of sensors to monitor the overall running status of the car, including air conditioning system sensors, air flow sensors (MAF), Intake manifold pressure sensor (MAP), crankshaft position sensor (CKP), camshaft position sensor (CMP), engine coolant temperature sensor (ECT), intake air temperature sensor (IAT), exhaust temperature sensor, throttle opening Degree sensor, knock sensor, oil pressure sensor, vehicle speed sensor, hydraulic oil temperature sensor, etc.
Safety system sensors mainly include collision sensors, safety sensors, central airbag sensors, seat belt sensors, and occupant distinction sensors, among which collision sensors are divided into front collision sensors and side collision sensors. The main function is to judge the intensity and direction of the collision when the car collides, and then determine whether the airbag is detonated.
