Embodiment 1

[0023] Embodiment 1: A vehicle safety system, comprising wheel speed sensors installed at different positions of the vehicle, vehicle roll sensors installed at the front and rear of the vehicle, and wear temperature sensors installed at the position of the brake pads of the vehicle, wherein the wheel The speed sensor uses a high-precision Hall-type ABS wheel speed sensor to measure the initial speed v of the car within the same time interval 1 and final velocity v 2 , the vehicle inclination sensor installed at the front and rear of the car can sense the height difference Δh between the front and rear wheels of the vehicle when the car is driving on a gentle road or on a slope. The wear temperature sensor installed at the position of the automobile brake pad can detect whether the brake lining is in a reasonable thickness range while sensing the temperature of the brake lining, and whether the brake lining needs to be replaced and treated. The signals sensed by the above diff...

Embodiment 2

[0024] Embodiment 2: A wear temperature sensor used in a vehicle safety system, which includes a wear end with a multi-level alarm device, and the loop circuit in the wear end is connected to the input end of the secondary instrument after being connected in series with the thermistor PT100, The secondary instrument can input the resistance value by receiving the wear terminal and compare it with the set resistance value, and then send the temperature signal output voltage signal and the brake wear output voltage signal to the automobile ECU through the output port, so as to help the ECU obtain the braking effect at this time. The temperature of the linings and the wear state of the brake linings. The wear end includes three-stage loops, which are respectively a loop with no resistance in series, a loop with a series resistance R1, and a loop with a series resistance R2. The resistor R1 and resistor R2 are all 1KΩ resistors, and the thermistor PT100 changes with the change of ...

Abstract

The invention provides a vehicle safety system and an abrasion temperature sensor thereof, and belongs to the field of vehicle safety systems. The vehicle safety system is used for vehicle driving, and comprises a vehicle ECU and further comprises a wheel speed sensor, a vehicle tilting sensor, a brake signal sensor and the abrasion temperature sensor, wherein the wheel speed sensor, the vehicle tilting sensor, the brake signal sensor and the abrasion temperature sensor are connected with the vehicle ECU through automobile wire harnesses. The automobile ECU processes information according to mg delta h+1 / 2*m*(v12-v22)=k*m'C delta T and stores data. According to the technical scheme, under the condition that vehicle information and road condition information are synthesized, factors affecting vehicle safety driving are pre-warned, and the guarantee of vehicle safety driving is improved.

Description

technical field [0001] The present application belongs to the field of vehicle safety systems, and in particular, particularly relates to a vehicle safety system and a wear temperature sensor thereof. Background technique [0002] During the transportation of the vehicle, the working condition of the braking system is obviously affected by the road conditions. For example, in the southwest region of our country, the long-slope road section is more common. Under such road conditions, if the vehicle is braked for a long time, it will cause continuous friction and heat generation of the brake lining, which may exceed the brake lining. The maximum working temperature of the brake pad is about 300 ℃, and the temperature of the brake pad can reach 400~500 ℃ at the highest. The heating of the brake pads will cause the friction performance of the brake pads to decrease, which will lead to brake failure or high temperature ignition of vehicle tires. [0003] How to judge the workin...
