Vehicle brake safety detection system

Abstract

The invention discloses a vehicle brake safety detection system, and belongs to the field of brake detection systems. According to the vehicle brake safety detection system, in the scheme, the safety of a vehicle brake system is judged through detection of friction sound between a brake disc and a brake pad, and potential risks of the vehicle brake system can be found in time; the situation that the vehicle is started to run with the potential risks can be avoided; a sound attenuation protection cluster is used for protecting an audio frequency input device, and the influence of an external sound source is reduced; meanwhile, when the vehicle runs onto a muddy road, muddy water mixtures are not prone to adhere to the audio frequency input device; when the detected sound source is matched with the sound source with the brake pad which is about to be worn to the limit, a vehicle-mounted control terminal can give an alarm to a vehicle body; on one hand, the speed of the vehicle is limited, and on the other hand, corresponding information is provided for traffic police through an Internet of Things technology; the traffic police forcibly maintain the vehicle, and the possibility that the vehicle runs on the road with the potential risks is reduced; and the running safety of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of brake detection systems, more specifically, to a vehicle brake safety detection system. Background technique [0002] Braking, also known as braking, refers to the action of stopping or reducing the speed of running locomotives, vehicles and other means of transport or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, The corresponding brake shoes, belts or discs are installed on the seat to generate braking torque under the action of external force. The antilock brake system (antilockbrake system) is called ABS for short. The function is to automatically control the braking force of the brake when the car is braking, so that the wheel is not locked and is in a state of rolling and sliding (slip rate is about 20%), so as to ensure that the adhesion between the wheel and the ground is at the maximum. .

[0003] The main monitoring method of the existing vehicle brake system is to monitor the thickness of the brake pads. Once the remaining thickness of the brake pads reaches the preset dangerous range, the on-board system will issue an alarm, and the vehicle dashboard will display that the thickness of the brake pads is too high. low, when Figure 9 As shown, if the driver drives the vehicle to a professional inspection and maintenance organization such as a 4S shop in time to troubleshoot or replace the brake pads, the threat of the vehicle will be eliminated and the vehicle will become a safe vehicle again. If it is inspected and maintained, the vehicle will be sick on the road, the braking distance will increase significantly, and the risk of driving will also increase accordingly.

[0004] In practice, brake pads are usually prone to failure at a thickness of 0.5cm, which is also the above-mentioned preset dangerous range. Once the brake pads are too thin, it is easy to directly appear through cracks and tears during the braking process, resulting in brake failure. The brake pads fail rapidly, and the braking effect of the brake pads declines like a cliff, resulting in a substantial increase in the braking distance of the vehicle, which seriously affects the safety of the vehicle.
