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(yīng)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(lǐng)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(jié)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(yán)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(yù)相結(jié)合的前瞻性雷達和視頻系統(tǒng)的數(shù)據(jù)，以提供一個完整的，準(zhǔn)確的，實時圖像的道路。當(dāng)這些數(shù)據(jù)表明的影響將是即將到來的，如果司機的轉(zhuǎn)向和制動干預(yù)是不夠的，以避免碰撞，制動壓力自動應(yīng)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.
