Abstract: PROBLEM TO BE SOLVED: To make control opening used for control correspond to a vehicle speed for an accelerator opening in a special traveling mode different from a normal traveling mode. SOLUTION: When the normal traveling mode is set, the accelerator opening Acc is set as a control opening Acc* as it is. When a fuel economy priority traveling mode is set, the control opening Acc* is set by using a map for setting the control opening. The map is set so that a low-sensitivity area in which the control opening Acc* is set to be smaller than the accelerator opening Acc has an accelerator opening range getting larger as the vehicle speed V gets higher and so that the low-sensitivity area includes the accelerator opening Acc necessary for constant speed travel. Power outputted from a power output device is reduced and an output of excessive power from the power output device is suppressed. Therefore, the fuel economy is improved.

解决方案：当设定正常行驶模式时，将加速器开度Acc设定为控制开度Acc *。 当设定燃油经济性优先行驶模式时，通过使用用于设定控制开口的地图来设定控制开度Acc *。 设定地图，使得控制开度Acc *设定为小于加速器开度Acc的低灵敏度区域，随着车速V变高，加速器开度范围变大，使得低灵敏度区域 包括恒速行驶所需的油门开度Acc。 从功率输出装置输出的功率减少，并且抑制来自功率输出装置的过大功率的输出。 因此，燃油经济性得到改善。 版权所有（C）2009，JPO＆INPIT

解决方案：当在二次电池的升温操作期间确定存在二次电池的连续充电/放电请求时，例如，控制器确定执行充电/放电所需的充电/放电继续功率 二次电池不断。 控制器确定充电/放电继续功率，使得通过将每个时刻的充电/放电限制功率乘以预定缩小常数α（0 <α<1）获得的减小功率不被超过。 由于充放电继续功率被抑制为充放电限制功率（充电限制功率WIN或放电限制功率WOUT）的α倍，因此，目前二次电池的极化作用被抑制，并且过电压变化 可以避免二次电池。 版权所有（C）2007，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To control the heat generation of a motor and incompatibility to a driver. SOLUTION: In a vehicle, a torque reduction rate value RT1 is set with a tendency of becoming smaller as road surface gradient α and vehicle weight M get larger (S340), when an absolute value of vehicle speed V is a threshold Vref or less, a previous torque command (previous Tm*) of a motor is a threshold Tmref or more, and a temperature rise promotion time t is a threshold Tmref or more. A torque command Tm* is set by subtracting the torque reduction rate value RT1 from the previous torque command (previous Tm*) of the motor (S400). The motor is driven and controlled with the torque command Tm* set up. Thereby, the temperature rise of the motor and an inverter driving the motor can be controlled by backing up a vehicle at more appropriate speed. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a controller for electric vehicle which prevents overvoltage from being generated, when limiting the torque of a motor at the occurrence of slippages. SOLUTION: The low μ control part 44 of an ECU40 directs a converter control part 41 (step S30) to reduce the input voltage (voltage VH) of an inverter, when it detects the road state(step S10) and determines that the load is in the state of low μ("YES" in step S20). Then, the low μ control part 44 directs a second inverter control part 43 to reduce the torque of a motor generator MG2 (step S50), when it detects the occurrence of slippage ("YES" in step S40).
