Signal control system for auxiliary brake of vehicle and control method

Abstract

The invention discloses a signal control system for an auxiliary brake of a vehicle and a control method of the signal control system. The signal control system comprises an analog quantity sensor and a main control chip, wherein the analog quantity sensor is connected to a main brake of the vehicle to detect the analog quantity of the main brake; the main control chip is in communicating connection with a velocity sensor and a rotational speed sensor of the vehicle to receive a velocity signal and a rotational speed signal of the vehicle and is also in communicating connection with the analog quantity sensor of the vehicle. The main control chip firstly judges whether the received velocity signal and rotational speed signal are both larger than a first preset value or not, if yes, the main control chip continues to judge whether the analog quantity of the main brake is larger than a second preset value or not, and if yes, the main control chip sends a start signal to the auxiliary brake. The signal control system has the advantages that an auxiliary braking system of the heavy-load engineering vehicle is controlled intelligently, and the braking distance can be shortened at the time of emergency braking; at the time of non-emergency braking, the main braking load can be reduced; when the vehicle goes down a slope under a heavy load, it can be guaranteed that the vehicle travels slowly, and travel safety is ensured.

Description

technical field [0001] The invention relates to engineering transport vehicle technology. More specifically, the present invention relates to a signal control system and control method of an auxiliary brake of a vehicle. Background technique [0002] With the rapid development of mining transportation tools, various large-tonnage equipment is constantly updated, and the curb quality of mining engineering transport vehicles has gradually increased from 40T to 90T or even higher. However, the braking performance of the whole vehicle cannot respond to the braking demand in a timely manner. Puzzled the development of large tonnage transport vehicles. The current braking system of large-tonnage engineering transport vehicles includes the main braking system of the whole vehicle and auxiliary braking systems such as engine exhaust braking and retarder braking systems. The main braking system of the vehicle is composed of a foot brake operating device, a vehicle air circuit and a...

Problems solved by technology

[0002] With the rapid progress of mining transportation tools, various large-tonnage equipment is constantly updated, and the curb quality of mining engineering transport vehicles has gradually increased from 40T to 90T or even higher. However, the braking performance of the whole vehicle cannot respond to the braking demand in time. Plagued by the development of large-tonnage transport vehicles

Such operation is easy to cause driving fatigue and other phenomena, and because the braking method is unscientific, overheating of the main braking system and insufficient braking force of the auxiliary braking often occur, resulting in the loss of braking ability of the whole vehicle and resulting in safety accidents
