To provide a driving control device and a driving control method of a wheel independent drive-type vehicle that can secure minimum power performance of driving the vehicle to a repair plant or the like and can perform control of overheat protection and enables a control system to be simplified, in the wheel independent drive-type vehicle.SOLUTION: A driving control device of a wheel independent drive-type vehicle comprises: temperature detecting means 23 each of which detects temperature of a motor 6 or of inverter 31 or of cooling/lubricating oil for each driving wheel; a torque upper limit setting part 39 that sets an upper limit of output torque of the motors 6 on the basis of detected temperatures; and abnormality detecting means 24 each of which detects whether or not an abnormality occurs in the temperature detecting means 23 corresponding to one of the driving wheels. When the abnormality detecting means 24 detects the abnormality occurring in the temperature detecting means 23 corresponding to the one driving wheel, torque values instructed to left and right driving wheels are set at the same values and upper limits of output torque of the left and right motors 6 and 6 are set, on the basis of the temperatures detected by the temperature detecting means 23 corresponding to the other driving wheel.SELECTED DRAWING: Figure 3
【課題】車輪独立駆動式車両において、修理工場等までの最低限の動力性能を確保し、且つ過熱に対する保護制御を行うと共に、制御系を簡単化することができる車輪独立駆動式車両の駆動制御装置および駆動制御方法を提供する。【解決手段】車輪独立駆動式車両の駆動制御装置は、駆動輪毎にモータ6またはインバータ31または冷却/潤滑油の温度を検出する温度検出手段23と、検出された温度に基づいて、モータ6の出力トルクの上限値を制限するトルク上限値設定部39と、一方の駆動輪に対応する温度検出手段23に異常が発生したか否かを検出する異常検出手段24とを備える。異常検出手段24により一方の駆動輪に対応する温度検出手段23に異常が検出されると、左右の駆動輪への指令トルクを同一値に設定し、且つ、他方の駆動輪に対応する温度検出手段23で検出された温度に基づいて、左右のモータ6,6の出力トルクの上限値を制限する。【選択図】図3
