  • Patent number: 11479234
    Abstract: An MG1 torque at a time of decreasing an engine speed of an engine is made larger when a turbocharging pressure by a turbocharger is higher than when the turbocharging pressure is lower. In this way, even if the losses of pumps of the engine differ due to the remaining turbocharging pressure during a transition of stopping the engine in turbocharging, it is possible to appropriately reduce the engine speed. Therefore, when the engine is being brought to a stop, it is possible to appropriately suppress vibration generated in the vehicle.

  • Patent number: 11453378
    Abstract: A method for controlling a drive train of a hybrid vehicle which includes an internal combustion engine, an electric machine that is operated as a motor or generator, and a transmission. Energy is recovered in the overrun operation of the vehicle by operating the electric machine in generator mode. The transmission has at least one free-wheel-connected low forward gear that only transmits traction torque, and at least one free-wheel-free high forward gear. When the free-wheel-connected low forward gear is engaged and the vehicle transitions into the overrun operation, or the driver requests a transition into the overrun operation by selecting the free-wheel-connected low forward gear, an overrun torque is set via the free-wheel-free high forward gear by a generator operation of the electric machine for energy recovery. The overrun torque thereby substantially corresponds to an overrun torque of a free-wheel-free configuration of the free-wheel-connected low forward gear.

  • Patent number: 11447110
    Abstract: When braking of the electric vehicle is performed, the braking is controlled based on a target braking split ratio which is a target value of the ratio of the braking force that is applied to the rear wheels to a total braking force that is applied to the front and rear wheels. In this case, an initial value of the target braking split ratio is set to a value within an allowable range about a transmission split ratio when braking of the electric vehicle is started while the electric vehicle is being braked by the motor, the transmission split ratio being the ratio of a braking force that is transmitted from a drive shaft to the rear wheels via a driving force split device to a total braking force that is transmitted from the drive shaft to the front and rear wheels via the driving force split device.
