  • Patent number: 8932180
    Abstract: A claw clutch includes first and second rotors disposed coaxially with each other, and is switched between an engaged state engaging teeth of the rotors and a disengaged state releasing the engagement. An actuator moves either one of the rotors in an axial direction to switch the clutch between the states. A synchronization controlling unit controls an electric motor coupled to the second rotor to cause its rotation number to approach the rotation number of the first rotor when the clutch is switched to the engaged state. An engagement controlling unit that controls the actuator moves either one of the rotors to a position where the teeth are engaged before a difference in rotation speed between the rotors falls within a predetermined range and the rotation number of the second rotor reaches that of the first rotor when the clutch is switched to the engaged state.

  • Patent number: 8437933
    Abstract: A hybrid electric vehicle has a first mode in which slippage of a clutch between an electric motor and a driving wheel is allowed and controlled by rotational speed control of the electric motor and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine. When the vehicle is stationary in the first mode, a controller reduces a control setpoint of hydraulic pressure of the clutch from an initial point. The controller identifies a reference point of the control setpoint with which actual output torque of the electric motor is substantially constant with respect to the reduction of the control setpoint. Then, the controller increases the control setpoint to a precharge point, and reduces the control setpoint to a corrected point that is lower than or substantially equal to the initial point and higher than the reference point.

  • Publication number: 20120253577
    Abstract: A method for disconnecting an electrical machine connected with the wheels of a vehicle's drive axle by means of a dog clutch having intermeshing couplers includes, upon receipt of a command to disengage, two successively activated steps. In the first step, a torque equal to a calibrated threshold of a target torque (d) is applied to the electrical machine so to effect a zero torque between the couplers. During this step, a dog clutch actuator is deactivated so to allow the dog clutch to disengage from the electrical machine as quickly as possible. Next, a torque having a value determined according to a slope whose value ranges from the calibrated threshold of the target torque (d) to zero is applied to the electrical machine.

  • Patent number: 5690580
    Abstract: A neutral apparatus for use on an electric vehicle is disclosed. The neutral apparatus comprises a control state detector and a neutral mechanism control circuit. The control state detector detects whether or not the motor control unit is in a predetermined control state. The neutral mechanism control unit can instruct the neutral mechanism to interrupt the power train according to the output signal from the control state detector. If the motor control unit is not in the predetermined control state, this is detected by the control state detector. In response to the output signal from the control state detector, the neutral mechanism control circuit causes the neutral mechanism to interrupt the power train. Thus, power flow from the motor to the drive wheels is interrupted. The control state detector is comprised of a voltage comparator circuit for comparing the output voltage from the motor driver circuit with a reference voltage and produces an output signal.
