PROBLEM TO BE SOLVED: To provide limitation of operation of a vehicle for securing appropriate and predictable cruising distance.SOLUTION: Vehicle operation (e.g., speed, acceleration) may be limited on the basis of various conditions. The condition is at least one of conditions such as a current charge condition of an electrical energy storage devices (e.g., batteries, super-capacitors or ultra-capacitors), history of the current charge condition, conditions related to a vehicle (e.g., total mileage, weight, size, drag coefficient), a driver or an operator of the vehicle (e.g., a history with respect to speed, acceleration, total mileage) and/or environmental conditions (e.g., ambient temperature, terrain). A controller controls at least one power converter so as to limit at least one of current and/or voltage supplied to a traction electric motor.SELECTED DRAWING: Figure 5
【課題】適正かつ予測可能な航続距離を確保する車両の動作制限を提供する。【解決手段】車両の動作(速度、加速度など)は、様々な条件に基づいて制限される。当該条件は、例えば、電気エネルギー蓄積デバイス(電池やスーパーあるいはウルトラキャパシタなど)の電流変化状態、その履歴、車両に係る条件(総走行距離、重量、大きさ、抗力係数など)、車両の運転者あるいは操作者(速度、加速度、総走行距離に係る履歴など)、環境条件(気温、地形など)の少なくとも1つである。コントローラは、トラクション電動モータへ供給される電流と電圧の少なくとも一方を制限するように、少なくとも1つの電力コンバータを制御する。【選択図】図5
