AI Technical Summary

Technical Problem

The prior art is difficult to directly measure the force applied to the brake pads when the vehicle is braking, which makes it difficult to detect brake pad wear problems in a timely manner, affecting the safety and reliability of the vehicle.

Method used

Using a multi-dimensional force sensor, by connecting one end to the vehicle's brake caliper shaft and the other end is connected to the brake pad, the horizontal friction force and vertical clamping force of the brake pad during braking is measured in real time.

Benefits of technology

It realizes accurate monitoring of the stress status of the brake pads, can output friction and tightening force data in real time, timely detects the fatigue or wear of the brake pads, and improves the safety and reliability of the vehicle brake system.

Abstract

The present invention discloses a device and method for measuring the braking force of a vehicle, the device comprising: a multi-dimensional force sensor, one end of the multi-dimensional force sensor is connected to the brake caliper shaft of the vehicle, and the other end of the multi-dimensional force sensor is connected to the brake pad, and is used to measure the horizontal friction force and vertical clamping force of the brake pad when the wheel is braked. By directly connecting the multi-dimensional force sensor to the brake pad, the force received by the vehicle during braking is directly measured, which has the advantages of high monitoring accuracy, strong real-time performance, high accuracy, and low misjudgment rate. The magnitude of the friction force value can be measured in real time in the short term or long term, and information on damage to the brake pad due to long-term force can be found to determine whether the brake pad is fatigued and loose, and whether it is in a normal working state, thereby solving the problem of difficulty in timely discovering the wear problem of the brake pad from the outside, facilitating timely replacement of the brake pad, reducing failures, thereby avoiding accidents, and greatly improving the safety and reliability of vehicle operation.
