Description

Wheel sensor

Technical Field

The invention relates to the technical field of vehicle sensors, in particular to a wheel sensor.

Background

The existing automobile rainfall sensor is hidden behind a front windshield glass, and the action of a windshield wiper can be adjusted according to the amount of rainfall falling on the glass, so that the trouble of a driver is greatly reduced. The rain sensor does not change the action speed of the windshield wiper by a plurality of limited gears, but performs stepless regulation on the action speed of the windshield wiper. It has a light emitting diode called LED for emitting far infrared rays, and when the surface of the glass is dry, light is reflected almost 100% so that the photodiode receives much reflected light. The more rain on the glass, the less light is reflected, with the result that the wiper action is faster.

The windshield wiper sensor and the windshield wiper controller are produced separately, linkage of the windshield wiper sensor and the windshield wiper controller is poor, in addition, if rainwater disappears on a front window suddenly due to sudden sunniness in the use process of the windshield wiper body, the windshield wiper body stops on the front window, not only is the driving implementation interfered, but also the windshield wiper body is easy to corrode, in addition, the installation and the disassembly of the windshield wiper sensor are also a more complex process, and the simplification is needed urgently;

in addition, the reversing radar system is frequently applied to passenger cars, but has some problems when applied to commercial vehicles such as trucks. Because the operation of the truck is severe, the radar sensor is easy to loosen or be damaged by vibration after being fixed on the truck, the radar sensor is fixed on a certain part of the vehicle in a practical pasting mode, a clamping mode and the like in the prior art, but after the radar sensor is used for a long time, the radar sensor is damaged due to the influence of factors such as severe vibration, cargo collision and the like, so that the use of a reversing radar system is influenced, and in rainy days, the sensitivity of the radar sensor is often influenced due to the interference of rainwater;

the automobile is continuously braked in the driving process, so that the brake pad is continuously abraded, and a driver is often unaware of the abrasion, so that the service life of the brake pad is greatly shortened due to the long-term abrasion; the heat generated by the automobile brake friction is large, when the temperature reaches high temperature, the brake pad is attenuated, and a driver still uses the brake pad excessively without knowing the brake pad, so that the safety problem is caused; after a period of use, the pressure coefficient between the brake block and the friction disc becomes low, which seriously affects the braking performance, but the driver is not aware of the situation and causes safety problems,

the present invention has been made to solve the above problems, and the conventional vehicle sensors are not good in cooperativity because they operate independently, and do not solve the above problems.
