    Abstract: A regeneration controller that is employed in a hybrid system is configured to control a regenerative braking amount of a motor generator. A hydraulic brake is configured such that a hydraulic braking amount applied to a vehicle is decreased after the depression amount of the brake pedal is decreased by a predetermined first hysteresis amount from the start of a decrease in the depression amount. The regeneration controller is configured to control the motor generator such that, when the depression amount of the brake pedal is decreased, the regenerative braking amount starts decreasing after the depression amount of the brake pedal is decreased by a second hysteresis amount from the start of a decrease in the depression amount. The second hysteresis amount is set to be greater than the first hysteresis amount.

  • Publication number: 20190226440
    Abstract: When an engine is stopped, a rotational position at a time when a crankshaft starts rotating in a reverse direction is predicted based on a rotational position detected by a crank angle sensor. A target rotational position is set within a range of the crankshaft rotational position between a time when the exhaust valve of one of four cylinders in the expansion stroke when the crankshaft starts rotating in the reverse direction is opened and a time when the expansion stroke of the cylinder ends. When the predicted rotational position is behind the target rotational position, a torque applying device applies a positive rotational torque to the crankshaft. At the time when the exhaust valve of the cylinder in the expansion stroke when the crankshaft starts rotating in the reverse direction is opened, application of the positive rotational torque from the torque applying device to the crankshaft is stopped.

  • Publication number: 20190210588
    Abstract: When the state of charge of a battery is greater than or equal to a lower limit value and less than or equal to an upper limit value, an electronic control unit calculates a charging electric energy transferred between a motor-generator and the battery such that the battery is neither charged nor discharged. When the state of charge is less than the lower limit value, a required torque of the engine is calculated based on the charging electric energy, a power consumption of an auxiliary device, and a driving torque. When the state of charge is greater than or equal to the lower limit value and less than or equal to the upper limit value, the required torque is calculated based on the charging electric energy and the driving torque, without taking the power consumption into consideration.
