Design and Research on the Safety Control System of a Bus

Abstract:

In order to improve the safety of buses, based on the research of bus tyre pressure and temperature monitoring system, the control strategy of independent safety control system is proposed, namely in the tyre abnormal initial sound warning prompt, later will enter the fault mode engine "limp home", limiting the power and velocity of the engine, but in the tyre burst or rapid leak the emergency braking control system can take effects for bus, while the engine is "idle" working mode, the driver controls the direction of travel and brake on the bus is just as input of emergency braking control system. Compared with the traditional tyre pressure monitoring system, the system can not only realize the tyre pressure abnormal warning, but also realize the emergency brake control, and the safety of control system which has been installed on the VDS A01 models achieve the basic performance requirements for our design. It has good practical value.
