  • Patent number: 10828989
    Abstract: A hybrid vehicle is operated with a combustion engine, an electric machine and a gear unit. The vehicle has a first electrical system and a second electrical system as a vehicle electrical system. The first electrical system, which is operated at a higher voltage level than the second electrical system, operates the electric machine, an electrical energy storage device, an energy converter that transmits electrical power at least from the first electrical system into the second electrical system. An alternator is not used in the second electrical system. The first electrical system is a part of a transmission system that together with the components that are coupled to the transmission system is controlled by a transmission control unit. During power generation by the electric machine the energy supply of the second electrical system has a higher priority than a motor-mode support of the drive by the electric machine.

  • Patent number: 10801619
    Abstract: A parking lock device includes a parking mechanism, a lock state switching member, a selector, a gradient detector, a switching controller, and an engine speed controller. The lock state switching member locks a parking gear when supply of hydraulic pressure is stopped. When hydraulic pressure is supplied, the lock state switching member releases the lock of the parking gear. The selector receives operation to select a shift range. The gradient detector detects a gradient of a road surface. When a parking range is selected, the switching controller stops supplying the hydraulic pressure to the lock state switching member. When another shift range is selected, the switching controller supplies the hydraulic pressure to the lock state switching member. When the parking range is selected and the gradient of the road surface is equal to or larger than a predetermined value, the engine speed controller increases an engine speed.

    Abstract: A power-split hybrid transmission includes a direction reversing mechanism between the transmission input and a power-splitting planetary gear set. The transmission input is driven by an internal combustion engine. Engaging the direction reversing mechanism to drive the carrier in a direction opposite of engine rotation permits the transaxle to achieve higher output torque in reverse when using predominantly engine power. The direction reversing mechanism may also be used to hold the carrier stationary, providing a torque reaction to propel the vehicle with a generator, thus increasing the output torque in both directions when operating under only battery power.

The second clutch is provided in the second power transmission path to select a connection state between a second connecting state and a second disconnecting state. The circuitry is configured to control the first clutch and the second clutch such that the second clutch switches to the second disconnecting state in a case where the first clutch switches to the first connecting state so as to transmit the power from an internal combustion engine to a wheel and where a vehicle speed of the vehicle is larger than a first vehicle speed threshold value.

  • 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: 10315507
    Abstract: A hybrid vehicle includes a clutch and a transmission unit configured to be able to switch into a neutral state. The hybrid vehicle is able to transmit power of an engine through any one of a first path through which power is transmitted from the engine to a first MG via a transmission unit and a differential unit and another second path through which power is transmitted from the engine to the first MG. The clutch is provided in the second path, and switches between an engaged state and a released state. The controller controls the engine, the first MG, the transmission unit and the clutch. The controller sets the transmission unit to a non-neutral state, sets the clutch to the engaged state, and then causes the vehicle to travel by using driving force from the first MG and driving force from the second MG.

  • Patent number: 10197134
    Abstract: An electro-magnetically actuated pawl clutch is adapted to establish a fixed overdrive ratio in a powersplit type hybrid gearing arrangement. The electro-magnetically actuated clutch includes a first race splined to the transmission input shaft and a second race integrally formed into a first gear that is supported for rotation about the input shaft. Electrical current in a non-rotating coil establishes a magnetic field in the first race. The magnetic field causes a set of pawls to pivot with respect to the first race and to engage a cam surface in the second race. The pawls and cams are designed such that, when engaged, the second race can rotate faster than the inner race but cannot rotate slower. The first gear meshes with a second gear fixed to the transmission output shaft.
