Welcome to May Auto Parts Manufacturing & Supplying (MAPMS)
There are many sensors in the car, and the car also relies on the sensors to work. The sensors detect signals and feed back to the car computer, which controls the corresponding parts to work. If the sensors are damaged, the corresponding parts will not work properly and the car will not work properly.
There are many sensors on the car, and the car also works with the help of sensors, which detect the signals, feed back to the car computer, and control the work of the corresponding components through the computer. If the sensors are destroyed, the corresponding components will not work properly, and the car will not be able to be used properly.
There are many auto sensors, which can be divided into two categories: environmental monitoring sensors to detect and recognize the surrounding environment, is necessary to complete the driverless sensor; body cognitive sensors to obtain the body information content, such as tire 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, car crank sensor, speed sensor, engine blast sensor and oxygen sensor, etc. The following is part of the basic principles and use of automotive sensors.
The air flow signal accurately measures the amount of air sucked in by the car engine, which is converted into an electrical signal and given to the ECU as a standard signal between fuel injections. Inquiry maf mass air flow sensor.
Car ABS sensor is generally located in the tire 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, the braking system to control the wheel has inhibited the rotation, in order to achieve the best brake pedal actual effect;.
TPS throttle position sensor 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 standard signal for ignition advance angle and ignition advance angle adjustment.
Giving the standard part signal of engine crankshaft inflection angle as the main control signal of engine injection timing control and ignition timing control. For bulk car camshaft sensor.
Checking the lower stop signal, engine crankshaft inflection angle signal and vehicle speed signal, giving to ECU as the standard signal for specifying ignition timing, engine injection timing and working order by using car crankshaft sensor.
Check the real-time travel rate of the car, to the ECU to transmit the hourly speed signal for fixed speed cruise control and speed limit off control, is also the main control signal of the automatic transmission.
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 work pressure caused by the mass block vibration, in the 2 pole surface caused by the working voltage, the vibration is converted to work voltage signal output.
