ACC系統(tǒng)結(jié)構(gòu)是一種智能化自動(dòng)控制系統(tǒng),是定速巡航控制系統(tǒng)的升級(jí)。其中,區(qū)別在于ACC以雷達(dá)、相機(jī)為傳感器,持續(xù)掃描車輛前方道路,探測(cè)前方障礙物的距離、速度,同時(shí)結(jié)合駕駛員意圖和自車運(yùn)動(dòng)狀態(tài),決策安全跟車距離和安全跟車速度。當(dāng)與前車之間距離過小時(shí),ACC控制單元可以通過與制動(dòng)防抱死系統(tǒng)、發(fā)動(dòng)機(jī)控制系統(tǒng)協(xié)調(diào)動(dòng)作,使車輪適當(dāng)制動(dòng),使發(fā)動(dòng)機(jī)的輸出功率下降,使車輛與前方車輛始終保持安全距離。
