2.计算机控制技术在底盘上的应用(1)制动防抱死控制系统(ABS)与驱动防滑控制系统(ASR)。ABS和ASR都是防止和控制汽车在行驶中出现“打滑”现象的电子控制系统。汽车在行驶中的“打滑”有2种概念:一是汽车制动时,车轮在路面上发生抱死拖滑移动现象;二是当汽车在泥泞、冰雪的路面上行驶,尤其是在起步或加速行驶时,常会发生驱动轮在旋转,而汽车却原地不动即驱动轮滑转现象。这2种情况都容易使汽车发生侧滑而进入危险状态,应予防止和控制。ABS解决前者,ASR解决后者。
2 computer control technology in the chassis (1) brake anti-lock control system (ABS) and drive anti-skid control system (ASR). Both ABS and ASR are electronic control systems that prevent and control “skidding” of a car while driving. Car driving in the “slippery” there are two concepts: First, the car brake, the wheel lock on the road slip phenomenon; second, when the car in the muddy, snow and ice driving the road, especially in the start or When accelerating, it often happens that the driving wheel is rotating while the car is not moving, that is, the driving wheel slips. Both of these two situations can easily cause the vehicle to slip and enter into a dangerous state, which should be prevented and controlled. ABS to solve the former, ASR solve the latter.
