Motor bus active rollover-preventing control system based on electromagnetic suspension adjustment

Abstract

The invention provides a motor bus active rollover-preventing control system based on electromagnetic suspension adjustment and belongs to the technical field of motor bus active safety control. According to the control system, various sensors collect the accelerated speed signal of a motor bus, the turn angle signal of a steering wheel, the rollover position signal of a bus body, the bus speed signal and the heading angle speed signal, the current driving state of the motor bus is determined and whether the next state of the motor bus has the rollover tendency or not is predicted after signal processing, the height of the two sides of a bus frame is adjusted by controlling suspension displacement control solid-state relays, the motor bus is prevented from rolling over in the driving process, and the driving safety of the motor bus can be improved.

Description

technical field [0001] The invention relates to the field of active safety control of buses, in particular to an active anti-rollover control system for buses based on electromagnetic suspension adjustment. Background technique [0002] In recent years, with the increase of the population and the increase in the number of times people go out, the number of times of choosing a bus to travel is also increasing. Relatively speaking, the active safety control technology of the bus is relatively lacking, and most buses only install a safety system of ABS. , and in order to improve the comfort of passengers and increase the passenger capacity, the position of the center of mass of the bus is high, the body is long, and it is more prone to rollover when driving at high speed. Once a rollover accident occurs, it will cause serious casualties and property losses; at present, The use of mechanical structures such as hydraulic actuators, oil-pneumatic suspensions, and active anti-roll ...

[0002] In recent years, with the increase of the population and the increase in the number of times people go out, the number of times of choosing a bus to travel is also increasing. Relatively speaking, the active safety control technology of the bus is relatively lacking, and most buses only install a safety system of ABS. , and in order to improve the comfort of passengers and increase the passenger capacity, the position of the center of mass of the bus is high, the body is long, and it is more prone to rollover when driving at high speed. Once a rollover accident occurs, it will cause serious casualties and property losses; at present, The use of mechanical structures such as hydraulic actuators, oil-pneumatic suspensions, and active anti-roll bars has achieved the active anti-rollover of buses to a certain extent, but the hydraulic transmission of hydraulic actuators, oil-pneumatic suspensions, etc. has a certain hysteresis. When the rollover behavior occurs, it is impossible to respond at the best rollover adjustment time. The structure of the active anti-roll bar is complex, and the arrangement of the anti-roll bar on the frame may affect the normal driving of the car. There are certain defects and deficiencies in the rollover control device
