The Working Principle and Function of Auto Sensors

1. What is the car sensor?

It converts the information of various operating conditions of the car, such as speed, temperature of various media, engine operating conditions, etc., into electrical signals to the computer, so that the engine is in the best working state.

There are many sensors in the car. When judging the fault of the sensor, we should not only consider the sensor itself, but also consider the whole circuit of the fault. Therefore, in the search for faults, in addition to checking the car sensor, but also check the wiring harness, plug and sensor and electronic control unit between the relevant circuit.

2. The working principle of the car sensor

We know the role of the auto sensors is to convert some signals we need to detect into electrical signals and output, so that we can judge the current state of the system through the feedback signal back.

Vehicle speed sensor is a device that it by measuring electric car speed and specific speed signal into electric signal transmitted to the car at the core of the control computer, control computer with the input signal to determine the state of operation, and issuing commands to control the engine idle speed, it can also realize the automatic transmission torque converter locking, Automatic transmission shift and car engine cooling fan open and close and cruise speed and other functions.

Overall, the car was going to be safe and effective, in addition to need some transmission mechanism, generator, ignition devices such as the large mechanical equipment, also need through the speed detection to real-time detection of our speed, whether car or acceleration deceleration, or we need to stop the car running, auto sensors play an important role.

3. The role of car sensors

Engine control system sensor is the core of the whole automobile sensor, there are many kinds, including temperature sensor, airbag pressure sensor, position and speed sensor, flow sensor, gas concentration sensor and automotive knock sensor, etc. For ECU to accurately control engine working conditions, to improve engine power, reduce fuel consumption, reduce exhaust emissions and fault detection.
