你的疑問這影片就解答了
仔細看雪地測試那段 柏油雪地交替測試
這次BYD展示的技術就是每輪電機都是獨立控制的
由電腦判斷車主當下要做的行為 及輪下路面材質
然後下不同的指定給每個電機該出力多少
所以只要程式寫的很好及硬體到位
就不會出現打滑或者行駛方向走偏
即使一輪路面突然材質有變化 或是突然爆胎
每個輪電機就會出現不同的出力狀態
即使一輪踩柏油 一輪踩雪 一輪踩砂 一輪踩水
電腦都可以毫秒級的計算
控制每個輪電機的扭力分配
達成不打滑的安全行駛
這是油車無法辦到的 即使加上一堆電子輔助也不可能
因為內燃機響應速度無法像馬達這麼快
如果應用在超跑上(可能U9就有應用)
就會讓車成為過彎神器
BYD這技術確實很厲害

推 iamstudent : 麥克輪應該只能在很平又堅硬的地面才能這樣運作 01/05 22:09
→ iamstudent : 像倉庫那種地面都沒問題 01/05 22:10
→ iamstudent : 可是到了有起伏的道路上,可行性很令人質疑 01/05 22:11
→ iamstudent : 停路邊假如有一輪踩在鐵格會滑 01/05 22:12
→ iamstudent : 還能橫向開的出來嗎? 01/05 22:12
→ iamstudent : 假如高速煞車左右兩邊抓地力不同 01/05 22:15
→ iamstudent : 這種輪子還可以產生額外的橫向推力 01/05 22:15
