  • Patent number: 10407051
    Abstract: An apparatus and method for controlling driving of a hybrid vehicle are provided. The apparatus includes a state identifying unit that identifies a driving state of a vehicle based on driving information of the vehicle during lock-up driving of the vehicle and a determination unit that determines whether the identified driving state satisfies a preset lock-up charge driving mode entering condition and determines a deceleration volition of a driver based on the identified driving state. When the identified driving state satisfies the lock-up charge driving mode entering condition a driving controller interrupts the vehicle from entering into a lock-up charge driving mode when the driver has a deceleration intention.

  • Patent number: 10333450
    Abstract: Systems and methods for controlling the operating speed and the torque of an electric motor using an operational model are described. An operational model for the electric motor, including a plot of engine performance parameters, is used for reference, and a most efficient output path, which may pass through an optimal operation region in the operational model, is selected. The most efficient output path may be determined, for example, according to locations of a current output state and a to-be-reached target state in the operational model, enabling the operating state of the motor to reach the target state from the current operating state. By selecting a more efficient output path, the operating efficiency of the motor may be optimized, the life of a battery improved and/or the operating mileage of the vehicle may be increased, without significantly reducing the driving experience.

  • Patent number: 9941829
    Abstract: Systems and methods for controlling the operating speed and the torque of an electric motor using an operational model are described. An operational model for the electric motor, including a plot of engine performance parameters, is used for reference, and a most efficient output path, which may pass through an optimal operation region in the operational model, is selected. The most efficient output path may be determined, for example, according to locations of a current output state and a to-be-reached target state in the operational model, enabling the operating state of the motor to reach the target state from the current operating state. By selecting a more efficient output path, the operating efficiency of the motor may be optimized, the life of a battery improved and/or the operating mileage of the vehicle may be increased, without significantly reducing the driving experience.

  • Patent number: 9925885
    Abstract: A control system for a vehicle including an engine, an electrical storage unit and a generator driven by the engine, the control system includes a socket and a controller. The socket is configured to supply electric power from the generator or the electrical storage unit to a device outside the vehicle in a travel stop state. The controller stops the engine when a preset condition is satisfied. The controller sets a first range and a second range in which the condition is satisfied. The first range is the range in a case where electric power is supplied to the device outside the vehicle and the second range is the range in another case. The first range is narrower than the second range.

  • Patent number: 9800064
    Abstract: A control system includes a state-of-charge (SOC) measuring unit and a controller. The SOC measuring unit measures a SOC of a first battery pack and a SOC of a second battery pack. The controller adjusts the SOC of the first battery pack and the SOC of the second battery pack. When a difference between the SOC of the first battery pack and the SOC of the second battery pack is less than a first threshold value, the controller performs an adjustment to adjust the SOC of the first battery pack and the SOC of the second battery pack so that said difference becomes equal to the first threshold value. An average of the SOC of the first battery pack and the SOC of the second battery pack before the adjustment is equal to an average of the SOC of the first battery pack and the SOC of the second battery pack after the adjustment. The controller pulse-charges or pulse-discharges the first battery pack and the second battery pack using a first C-rate.
