PROBLEM TO BE SOLVED: To provide a drive control device for a wheel independent drive type vehicle which eliminates instability behavior at the time of load limitation of a torque of a motor during high speed travelling and enables saving action even if one side wheel falls.SOLUTION: Left and front drive wheels 2 of at least one of front and rear wheels are applied to a drive control device 20 in a vehicle which can be independently driven by separate motors 6. Malfunction detection means 34, which detects malfunction such as overheating or failure occurs in any one of the motor 6, and a detection system, a power supply system and a wiring system for drive of the motor, is provided. Malfunction correspondence torque distribution changing means 35, which performs, for any one of the motors 6, a load limitation of a torque which is determined for every speed range according to which speed range a current vehicle speed falls when malfunction is detected by said means 34, is provided.SELECTED DRAWING: Figure 3
【課題】 高速走行時のモータのトルクの出力制限時の不安定挙動を無くすと共に、片輪が失陥したとしても退避行動を可能とした車輪独立駆動式車両の駆動制御装置を提供する。【解決手段】 前後輪のうちの少なくとも一方の左右の駆動輪2を個別のモータ6で独立して駆動可能な車両における駆動制御装置20に適用する。モータ6およびその駆動のための検出系,電力供給系,配線系のいずれかに過熱または失陥である異常が発生したことを検出する異常検出手段34を設ける。この手段34により異常が検出された場合に、現在の車速がいずれの速度領域にあるかに応じ、速度領域毎に定められたトルクの出力制限を前記いずれかのモータ6に対して行う異常対応トルク配分変更手段35を設ける。【選択図】 図3
