  • Patent number: 10688871
    Abstract: A regenerative braking control apparatus equipped on an electrically driven vehicle having road wheels and an electric motor for driving the road wheels for running. An operation unit is provided for the driver of the vehicle to select a magnitude of the braking force to be generated by the electric motor during regenerative braking. A determination unit determines, on the basis of conditions of the electrically driven vehicle, whether or not a selected braking force selected through the operation unit is acceptable. A notifier unit is constructed such that, in a case where the selected braking force is determined to be unacceptable by the determination unit, the notifier unit provides a corresponding notification to the driver.

  • Patent number: 10513257
    Abstract: An ignition switch is turned on, and when an abnormality is detected in any of electronic control instruments or sensors, real failure is established, and a fail-safe process is performed. After a lapse of a predetermined period from the establishment of the real failure, fault determination is established, a failure level is sent, and a hybrid fail-safe process is performed. Then, when the abnormality is eliminated, the real failure is not established, and the fail-safe process of an engine is finished. Then, when the ignition switch is turned off and then again turned on, sending of the failure level to a hybrid control unit is stopped, and the hybrid fail-safe process is finished.

  • Patent number: 6377007
    Abstract: A motor torque control device of an electric vehicle sets creep torque in accordance with a vehicle speed sensed by a vehicle speed sensor, and sets acceleration torque in accordance with an accelerator control input sensed by an acceleration sensor. Then, the motor torque control device calculates a torque command value by adding the creep torque to the acceleration torque. It is therefore possible to quickly raise the acceleration torque immediately when an accelerator is operated to start the vehicle. It is also possible to prevent a sharp decrease in the torque command value since the torque command value reflects the creep torque even after the start of the vehicle.
