Motor coach running safety auxiliary system and control method thereof

Abstract

The invention discloses a motor coach running safety auxiliary system and a control method of the motor coach running safety auxiliary system. The motor coach running safety auxiliary system comprises an air compressor, a wet gas reservoir, a front brake chamber, a rear brake chamber, a front main gas reservoir, a rear main gas reservoir, a double-cavity brake valve upper cavity, a double-cavity brake valve lower cavity, each spring brake chamber, an ABS electronic control unit and an ABS pressure regulator. The motor coach running safety auxiliary system is characterized in that in the safety auxiliary system, a first electromagnetic gas channel directional valve is arranged in the brake gas channel positioned between the front brake chamber and the front main gas reservoir, a second electromagnetic gas channel directional valve is arranged in the brake gas channel positioned between the rear front brake chamber and the rear main gas reservoir, and electromagnetic quick-release valves are arranged in the spring brake chambers in a one-to-one correspondence manner. By applying the motor coach running safety auxiliary system and the control method of the motor coach running safety auxiliary system, a motor coach is controlled to be braked and stopped running at a reasonable deceleration in case of paroxysmal diseases of the driver, parking braking is started, and the running safety is guaranteed.

Description

technical field [0001] The present invention relates to a driving safety assisting system of a bus and a control method thereof, in particular to a driving safety assisting system of a bus and a control method thereof in the case of sudden serious illness of a driver. Background technique [0002] In recent years, with the rapid development of my country's transportation industry, accidents of sudden and serious diseases of car drivers have occurred frequently. According to incomplete statistics, from 2006 to 2015, there were as many as 100 incidents of car drivers suffering sudden serious diseases while driving in my country, which were only publicly reported by the media, bringing serious road traffic safety hazards. Especially for buses, due to the large number of passengers, once the driver suddenly gets sick and causes a road traffic accident, it is very easy to bring great loss of life and property to the society. [0003] A series of studies have been carried out at ...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many components installed in the system, the modification is complicated, and the practicability is not strong

[0005] 2. Reasonable car deceleration is not considered when braking, which affects the comfort of passengers and is likely to cause rear-end collision accidents

[0006] 3. The parking brake cannot be realized after the vehicle is stopped. When the car is driving on a road section with a longitudinal slope, it is difficult for the motor and electromagnet to provide enough braking force to stop the car, which will easily lead to a slippery slope and road traffic accidents
