A vehicle parking brake detection reminder alarm system

Abstract

The invention provides a hand brake detection reminding alarm system of a vehicle. The hand brake detection reminding alarm system comprises a hand brake device and a driver seat and is characterized by comprising a hand brake detection switch, a seat sensor, an ultrasonic object detection radar, an alarm device, a central control unit and a power source. The power source directly supplies power to the central control unit, and the hand brake detection switch, the seat sensor and the ultrasonic object detection radar are connected with the central control unit; and the signal output end of the central control unit is connected with the alarm device through an electronic switch. The ultrasonic object detection radar is arranged within the detection range of the radar to cover the driver position on the driver seat, and the seat sensor is arranged in a seat cushion of the driver seat. If the seat sensor and the hand brake detection switch detect that a driver leaves the seat cushion of the driver seat, and the hand brake device does not carry out braking, the ultrasonic object detection radar monitors whether the driver leaves driving space or not; if the abnormity exists, alarm indication is sent to the central control unit, and the alarm device is controlled to send out an alarm reminding signal.

Description

technical field [0001] The invention belongs to the technical field of automobile brakes, and relates to an auxiliary device of a pneumatic hand brake system, in particular to a vehicle hand brake detection reminder alarm system. Background technique [0002] In modern society, cars have become an indispensable means of transportation for people to travel. With the increase of car ownership, the safety of cars has attracted great attention from the whole society. In addition to the safety of the car during driving, the safety of the car after it stops running (parked) (for example: the car slips for some reason) has also attracted the attention of all aspects of society. And because the driver forgets to start the "hand brake" device or has started the "hand brake" device but the consequences of automatically releasing it for some reason are not uncommon. [0003] Generally, after a small vehicle is parked, the driver will not only tighten the hand brake, but also the gear...

AI Technical Summary

Problems solved by technology

However, in some specific circumstances, the driver forgets to tighten the hand brake due to negligence, resulting in a slipping phenomenon, causing accidents

In addition, in the current vehicles, when a considerable number of vehicles (such as buses) are parked, the gear must be placed in the neutral position, otherwise the vehicle will not be able to start again.

After the hand brake device of this part of the vehicle is worn out, the function of self-locking is continuously reduced, and the hidden danger of automatic release is increasing. When it is not working, it will cause the hand brake handle to pop up automatically, making the parking brake of the car ineffective, causing the car to slide, and in serious cases, it will cause personal injury.
