There are many sensors on the car, and the car also works with the help of sensors, which detect signals and feed back to the car's computer, through which the corresponding components are controlled. If the sensors are destroyed, the corresponding components will not work properly and the car will therefore not be able to be used properly.

There are many automotive sensors, which can be divided into two categories: environmental monitoring sensors to detect and recognize the surrounding environment, is necessary to complete the unmanned sensor; body cognitive sensors to obtain the body information content, such as tyre pressure, steam pressure, speed, etc., is to maintain the car all normal, smooth, safe driving essential sensors.

The key sensors are: total gas flow sensor, ABS sensor, throttle part sensor, temperature sensor, engine camshaft part sensor, engine crankshaft part sensor, hourly speed sensor, engine blast sensor and oxygen sensor, etc. The following are some of the basic principles of automotive sensors and their use.

Total gas flow sensors

The total gas flow sensor accurately measures the amount of gas drawn into the vehicle engine and converts it into an electrical signal to the ECU as a standard signal between oil pump hours.

ABS sensors

ABS sensor sensor is generally located in the tyre near the rolling bearing part, in the wheel bearing outside, brake pads inside the hole, used to regulate the speed, in the emergency brake, the wheel rotation information feedback to the braking system, by the braking system to control the wheel has inhibited the rotation, in order to achieve the best brake pedal actual effect;.

Throttle area sensor

Throttle part sensor is installed on the throttle, used to check the opening degree of the throttle, according to the rod bar organization and throttle linkage, accurate measurement of the throttle opening perspective working voltage signal, and the signal will be sent to the ECU as the ignition advance angle and ignition advance angle adjustment of the standard signal.

Engine camshaft area sensor

Gives a standard engine crankshaft corner signal as the main control signal for the oil pump engine timing control and ignition timing control.

Engine crankshaft part sensor

Checking the lower stop signal, the engine crankshaft angle signal and the vehicle speed signal, which are given to the ECU as standard signals for specifying the ignition timing, the oil pump engine timing and the sequence in operation.

Speed sensor

checks the car's travel rate and gives the ECU an hourly speed signal for cruise control and speed limit off control, and is also the main control signal for the automatic transmission.

Engine vibration sensor

Check the engine oil pan vibration condition, for the electronics controller to identify the engine shock working condition. Engine shock, the car engine vibration according to the sensor within the mass block transmitted to the crystalline, piezoelectric crystalline because of the mass block vibration caused by the working pressure, in the 2 pole surface caused by the working voltage, the vibration is converted into a working voltage signal output.
