  • Publication number: 20170282894
    Abstract: A power controller of a hybrid vehicle includes: a first drive motor that drives any one of a front wheel and a rear wheel of a vehicle; an engine that drives the one wheel or the corresponding other one of the front wheel and the rear wheel of the vehicle through a clutch; a generator that is driven by the engine; and a voltage transformer that steps down generated electric power supplied to the first drive motor and a battery from the generator. The power controller limits passing power of the voltage transformer according to the temperature of the voltage transformer, and connects the clutch when the passing power of the voltage transformer is limited.

  • Publication number: 20170282897
    Abstract: In a hybrid vehicle including a front motor for driving front wheels, and a step-up converter for stepping up voltage from a battery to supply power to the front motor, in which power regenerated by rotational force of the front wheel during vehicle deceleration is stepped down by a step-up converter and can be supplied to a battery, the hybrid vehicle includes a hybrid control unit which computes maximum input power of the step-up converter and regenerated power of the front motor during vehicle deceleration, and sets a difference obtained by subtracting regenerated power of the front motor from the maximum input power of the step-up converter to the maximum generated power of the generator.

  • Publication number: 20170282898
    Abstract: In a hybrid vehicle including: a step-up converter for stepping-up the voltage from a battery and supplying power to the front motor for driving front wheels; as well as a paddle switch for setting regenerative braking torque stepwisely, and a hybrid control unit for calculating a regenerative braking force based on a selection stage set by the paddle switch, the hybrid control unit decreases the regenerative braking force to be less than the regenerative braking force while the maximum input/output power of the step-up converter is not limited, when a selection stage in which regenerative braking force is more than that in a D range is selected while the maximum input/output power of the step-up converter is limited.

  • Publication number: 20170282891
    Abstract: A hybrid vehicle including a front motor for driving front wheels, a rear motor for driving rear wheels, and a step-up converter for stepping-up the voltage from a battery and supplying power to the front motor, in which an engine is started to shift the vehicle from an EV mode into a series mode when the output power of the step-up converter is lower than the required power of the front motor, the hybrid vehicle includes a hybrid control unit which computes maximum output power of the step-up converter and, when the output power of the step-up converter is more than the maximum output power, increases the distribution ratio of the travel driving torque of the rear wheel, thereby increasing the output torque of the rear motor.

  • Publication number: 20170174202
    Abstract: A control device for controlling an electric vehicle includes a driving source that rotates wheels, a braking device that applies braking force to the wheels, a creep torque control portion that controls magnitude of creep torque to be applied to the wheels, wherein the creep torque control portion includes a braking force detecting unit that detects the braking force applied by the braking device, a fundamental creep torque calculating unit that calculates fundamental creep torque corresponding to vehicle speed, a creep suppression torque calculating unit that calculates creep suppression torque smaller than the fundamental creep torque based on a result of the detection of the braking force detecting unit and a creep torque calculating unit that calculate the creep torque by subtracting the creep suppression torque from the fundamental creep torque.
