  • Publication number: 20150088353
    Abstract: In an electric vehicle, a torque to rotate a drive wheel is generated by a motor. An accelerator grip is operated by a rider in order to adjust the torque of the motor. An operation amount of the accelerator grip is detected by an accelerator sensor. Further, a brake lever is operated by the rider in order to brake a main body. A controller is programmed to control the motor such that the torque of the motor gradually decreases when the brake lever is switched from a non-operation state to an operation state with the torque being generated by the motor.

  • Publication number: 20130312400
    Abstract: A variable displacement pump includes: a rotor mounted in a body; a cam ring mounted radially outside of the rotor, and arranged to move with a change in an eccentricity of the cam ring with respect to the rotor, wherein change of the eccentricity causes a change in a specific discharge rate; and an electromagnetic actuator arranged to actuate the cam ring for regulating the eccentricity. During control of operation of the electromagnetic actuator, a first response is set slower than a second response, wherein the first response is a response of movement of the cam ring to a change of an input signal in a direction to request a decrease in the specific discharge rate, and the second response is a response of movement of the cam ring to a change of the input signal in a direction to request an increase in the specific discharge rate.

  • Patent number: 8555628
    Abstract: A variable displacement pump including a drive shaft, a cam ring eccentrically moveable with respect to an axis of the drive shaft, and a solenoid drivingly controlled on the basis of variation in electric current amount to be supplied to the solenoid which is controlled in accordance with an operating condition of a vehicle. The solenoid is configured such that a rate of change in the specific discharge amount relative to the electric current amount to be supplied to the solenoid under a condition that the specific discharge amount is smaller is reduced as compared to a rate of change in the specific discharge amount relative to the electric current amount to be supplied to the solenoid under a condition that the specific discharge amount is larger.

  • Publication number: 20120004799
    Abstract: A power supply device of a hybrid car includes a driving battery 1 and a battery management system 2. The driving battery 1 can supply electric power to an electric motor 13 for driving the car. The battery management system 2 detects SOC of the driving battery 1, and transmits the detected SOC to the car. The battery management system 2 stores maximum SOC and minimum SOC relating to transmission of SOC to the car. When the detected SOC of the battery falls within a range between the maximum SOC and the minimum SOC, the detected SOC of the battery is transmitted to the car. When the detected SOC is not lower than the maximum SOC, the maximum SOC is transmitted to the car. When the detected SOC of the battery is not higher than the minimum SOC, the minimum SOC is transmitted to the car.

  • Publication number: 20120004875
    Abstract: The method of detecting battery internal resistance detects battery 1 temperature and internal resistance, and computes internal resistance at each temperature. In addition to detecting battery 1 temperature, the method detects battery 1 voltage and current at each detected temperature and computes internal resistance from the measured voltages and currents. Further, internal resistance computed from actual measurements establishes battery internal resistance versus measured temperature to determine internal resistance at a plurality of battery 1 temperatures.
