智能可变轮胎附着力系统的设计与应用

通过检测车轮速度及踩踏制动踏板的急缓程度,由电控单元判断,若是在紧急制动的情况下,控制电磁线圈通电,电磁作用使安装在轮辋上的泄气电磁阀动作,轮胎泄压,瞬间增大轮胎与地面的附着力,从而缩短制动距离;若是在冰雪、泥泞等特殊路面上,由电控单元通过电磁线圈控制泄气电磁阀,使轮胎泄半压,增大轮胎与地面的附着力,提高车辆的加速和制动性能,保持方向稳定。当紧急制动或特殊路面的情况消失之后,安装在轮辋上的充气阀将自动充气到轮胎的正常气压,并自动停止。

Integrated chassis control for a three-axle electric bus with distributed driving motors and active rear steering system

This paper describes an integrated chassis control framework for a novel three-axle electric bus with active rear steering (ARS) axle and four motors at the middle and rear wheels. The proposed integrated framework consists of four parts: (1) an active speed limiting controller is designed for anti-body slip control and rollover prevention; (2) an ARS controller is designed for coordinating the tyre wear between the driving wheels; (3) an inter-axle torque distribution controller is designed for optimal torque distribution between the axles, considering anti-wheel slip and battery power limitations and (4) a data acquisition and estimation module for collecting the measured and estimated vehicle states. To verify the performances, a simulation platform is established in Trucksim software combined with Simulink. Three test cases are particularly designed to show the performances. The proposed algorithm is compared with a simple even control algorithm. The test results show satisfactory lateral stability and rollover prevention performances under severe steering conditions. The desired tyre wear coordinating performance is also realised, and the wheel slip ratios are restricted within stable region during intensive driving and emergency braking with complicated road conditions.     

减速振动标线条间间隔及重复条数的设置研究
