轮胎路面附着系数实时感应识别系统

确保汽车安全平顺行驶所必需的力,例如,驱动力、制动力、换向力和车辙保持力等,均产生于轮胎与路面的摩擦接触面.实时感知路面附着系数和车轮载荷等,是最终实现汽车主动安全装置精确控制的必要条件.以德国开发的SAW轮胎传感器为例,介绍了轮胎路面附着系数电子感应识别系统的工作原理,展望了该系统在汽车主动安全控制方面的重要应用前景.

Electronic Sensing System for Real Time Identification of the Tire-Road Adhesion

All of the forces necessary for ensuring a safe and stable running of an auto e.g. driving and braking forces, directional turn and retain forces, come from the contact area of tire and road surface. If the current wheel loads and friction coefficient in the contact area can be determined in real time, a more accurate control to a variety of active safety equipments becomes possible. Take the SAW tire sensor developed by a German research team as an example, the working principle of the electronic sensing system for real time identification of tire-road adhesion is introduced and a perspective of the applications of the system on auto active safety controls is given.
