A blind guide vehicle system includes a body frame, a driving system, a ultrasound detection system and a control unit. The driving system, the ultrasound detection system and the control unit are provided on the body frame such that the driving system is operated to drive the body frame. The ultrasound detection system connects with the driving system and is operated to detect at least one barrier or a terrain change. The control unit connects with the driving system and the ultrasound detection system. A blind guide vehicle control method includes: when the ultrasound detection system detects the barrier or the terrain change, the control unit is operated to generate a warning signal.一種導盲車系統包含一車輛框體、一車輛行駛系統、一超音波偵測系統及一控制單元。該車輛行駛系統、超音波偵測系統及控制單元設置於該車輛框體,以便利用該車輛行駛系統行駛該車輛框體。該超音波偵測系統連接至該車輛行駛系統,且該超音波偵測系統偵測至少一環境障礙物或一地形變化。該控制單元連接至該車輛行駛系統及超音波偵測系統。一種導盲車控制方法為:當該超音波偵測系統偵測到該環境障礙物或該地形變化時,該控制單元發出一警示訊號。1‧‧‧車輛框體10‧‧‧外殼體101‧‧‧偵測孔102‧‧‧顯示面板103‧‧‧組合基座2‧‧‧車輛行駛系統3‧‧‧超音波偵測系統31‧‧‧上方偵測單元32‧‧‧前方偵測單元33‧‧‧下方偵測單元34‧‧‧左前方偵測單元34a‧‧‧左方偵測單元35‧‧‧右前方偵測單元35a‧‧‧右方偵測單元4‧‧‧控制單元41‧‧‧有線控制器5‧‧‧語音播報系統
