摘要： An engine stopping/starting control unit having improved accelerating performance. A charging limiting device is provided which limits the charge provided to a generator when the vehicle is stopped. The decreased charging allows for better performance when the vehicle accelerates from a stopped states. Also, the vehicle headlight can be dimmed while the vehicle is stopped, which reduces the load on the generator. An acceleration detector detects when the vehicle accelerates during running, and can decrease the generator load in response to the acceleration.

摘要： A discharge control apparatus in an electric motorcycle includes a main battery; a motor driven based upon electric power supplied from the main battery and a lighting device that is a load other than the motor for consuming electric power. A BMU determines a remaining capacity of the main battery. A control member performs a discharge control of the main battery for supplying electric power to the motor and the lighting device. The BMU and the control member allow the discharge of the main battery until the remaining capacity becomes a threshold value higher than zero. When the control member receives an instruction of checking a deterioration state of the main battery from an external checking device, the control member performs a discharge of the main battery until the remaining capacity reaches zero, and then, allows the main battery to be fully charged so as to determine a chargeable capacity.

摘要： An apparatus which estimates the temperatures of a motor without using a temperature sensor can achieve overheat protection by proper control. In an example, a heat generation amount calculation section calculates a heat generation amount of a motor. A current upper limit map has a current upper limit value corresponding to a temperature estimated value and a ratio map has a ratio corresponding to the temperature estimated value. A lower one of limited current values, determined using the two maps, controls energization of the motor. The heat generation amount calculation section includes a heat generation correction term, and a heat radiation correction term for calculating a function of the difference between the integrated value of the heat generation amount and a motor ambient temperature. If the ambient temperature becomes equal to or higher than a comparison temperature, then the heat generation amount is calculated without the heat radiation correction present.
