Beschreibung
Zusammenfassung:	Vehicle control apparatus includes: first/second shaft coupled with first/second drive wheel of vehicle; differential gear mechanism configured to distribute torque from motor to first/second shaft; sensor configured to detect first/second wheel rotation speed and motor rotation speed; and motor control unit including processor and memory. Motor control unit: calculates input rotation speed into differential gear mechanism based on motor rotation speed; calculates output rotation speed from differential gear mechanism based on first/second wheel rotation speed; calculates difference between input rotation speed and output rotation speed; determines whether duration of state in which difference exceeds predetermined value has exceeded determination time; and limits motor target torque to zero when it is determined that duration has exceeded determination time.
