電子制動輔助系統(tǒng)的傳感器解決方案

　　即使是在自主汽車出現(xiàn)之前，毫無疑問，先進的汽車應用正在把駕駛者的手從駕駛者手中抽走，特別是在基于傳感器的系統(tǒng)確定高速碰撞迫在眉睫的時候。特別是汽車制造商正試圖減輕潛在致命事故的一個領域是自動剎車系統(tǒng)。

　　研究表明，近一半的司機不踩剎車很快，足以阻止車輛在緊急情況下。因此，自動制動結合先進的駕駛員輔助系統(tǒng)和電子穩(wěn)定控制（ESC），以減緩車輛，并減少碰撞的嚴重程度時，碰撞是不可避免的。自動制動工作帶或不帶駕駛員干預相結合的前瞻性雷達和視頻系統(tǒng)的數據，以提供一個完整的，準確的，實時圖像的道路。當這些數據表明的影響將是即將到來的，如果司機的轉向和制動干預是不夠的，以避免碰撞，制動壓力自動應用提供最大的制動助力立即一旦司機從事剎車。這最后的行動是實現(xiàn)全ABS制動，并確保最大速度降低。

　　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.
