　　即使是在自主汽车出现之前，毫无疑问，先进的汽车应用正在把驾驶者的手从驾驶者手中抽走，特别是在基于传感器的系统确定高速碰撞迫在眉睫的时候。特别是汽车制造商正试图减轻潜在致命事故的一个领域是自动刹车系统。

　　研究表明，近一半的司机不踩刹车很快，足以阻止车辆在紧急情况下。因此，自动制动结合先进的驾驶员辅助系统和电子稳定控制（ESC），以减缓车辆，并减少碰撞的严重程度时，碰撞是不可避免的。自动制动工作带或不带驾驶员干预相结合的前瞻性雷达和视频系统的数据，以提供一个完整的，准确的，实时图像的道路。当这些数据表明的影响将是即将到来的，如果司机的转向和制动干预是不够的，以避免碰撞，制动压力自动应用提供最大的制动助力立即一旦司机从事刹车。这最后的行动是实现全ABS制动，并确保最大速度降低。

　　Recently in the news1 is a new “crash-proof car” that’s in the works at BMW. The car features Active Assist， a braking system that allows the vehicle to get within a certain range of another vehicle， and then takes over the braking for the driver automatically. Using laser sensors， the system effectively scans 360-degrees around the vehicle and will automatically and gently brake before a vehicle hits any stationary object.

　　It works in a manner not unlike cruise-control systems that automatically slow down a vehicle when you close too fast on the car in front： sensors in the BMW test car keep track of walls， columns， and other stationary objects， constantly maintaining and updating a digital map of the surrounding area. The company has demonstrated that if you drive its Active Assist car full throttle at a wall， the system will stop the vehicle inches away from impact without the driver touching the brakes.
