摘要： A hybrid vehicle includes an engine (10), a first motor generator (MG1), a second motor generator (MG2), a transmission unit (power transmission unit) (40), a differential unit (50), a clutch (CS) and a mechanical oil pump (501). The hybrid vehicle is able to switch between series-parallel mode in which power of the engine is transmitted via the transmission unit and the differential unit and series mode in which power of the engine is transmitted via the clutch. The differential unit (50) is a planetary gear mechanism including a sun gear (S2) connected to the first motor generator (MG1), a ring gear (R2) connected to the second motor generator (MG2), and a carrier (CA2) connected to a ring gear (R1) that is an output element of the transmission unit (40). The mechanical oil pump (501) is driven by power that is transmitted from the carrier (CA2) of the differential unit.

摘要： A hybrid powertrain system includes an internal combustion engine and a transmission arranged in a parallel configuration with a non-combustion torque machine to transfer traction power to a driveline. A method of controlling the hybrid powertrain system includes monitoring vehicle speed and an accelerator pedal position and determining a traction power command based thereon. A motor power that is input to the driveline from the torque machine is determined, and an adjusted engine power command is determined based upon the traction power command and the motor power from the torque machine. An adjusted accelerator pedal position is determined based upon the adjusted engine power command and the vehicle speed, and a preferred transmission state is determined based upon the adjusted accelerator pedal position and the vehicle speed. The transmission is controlled to the preferred transmission state.

摘要： A work implement requirement determination unit of a work vehicle determines a work implement required power based on the operation amount of a work implement operating member and the work implement pump pressure. A transmission requirement determination unit determines a transmission required power based on the vehicle speed and the operation amount of the accelerator operating member. When the sum of the work implement required power and the transmission required power is greater than a first distributable power that a predetermined preferential distribution power subtracted from a load upper limit power of the engine leaves, a distribution ratio determination unit allocates the smaller of a transmission compensation power and the transmission required power to a power transmission device and distributes the remainder of the first distributable power to the work implement pump and to a power transmission device.

摘要： When a driver turns on an accelerator, a CPU permits revolution of planetary gears, and a motor rotates a ring gear to drive wheels. Then, when the driver turns off the accelerator, the CPU calculates a target RPM to be output by a Stirling engine according to a depression amount and a depression time of the accelerator. When the RPM output by the Stirling engine reaches close to the target RPM, the revolution of the planetary gears is inhibited, the operation of the motor is stopped, and the Stirling engine rotates the ring gear via a sun gear and the planetary gears to drive the wheels.

摘要： When the driving force between a driven wheel of a wheel and the surface on which the vehicle is travelling exceeds the available traction, wheel slippage may occur. Wheel slippage may result in a loss of control of the vehicle. The present disclosure may facilitate the control of drive power sent to a driven wheel of a vehicle from consideration of a torque setting and a speed of the vehicle.

摘要： Systems and methods are provided for restarting an engine that can be selectively deactivated during idle-stop conditions. In one embodiment, the engine is restarted with torque reduction over an interval of the restart, for example, by upshifting the transmission. In response to a vehicle launch request, the torque reduction is decreased, for example, by downshifting the transmission, to expedite return of driveline torque.

摘要： A hybrid vehicle control apparatus is provided with an engine, an electric motor, a holding element, an automatic transmission, a range position detecting device and a controller. The holding element is arranged between the engine and the electric motor to selectively connect and disconnect the engine and the electric motor to and from each other. The automatic transmission is arranged between the electric motor and a drive wheel. The range position detecting device detects a range position of the automatic transmission selected by a driver. The controller executes a control operation serving to stop the engine while also executing a slip control serving to lower a torque transfer capacity of the holding element upon a determination that a request to stop the engine has occurred while the engine is operating, the holding element is engaged, and the automatic transmission is detected in a non-driving range.

摘要： A requested cruise-control horsepower calculator obtains a requested cruise-control horsepower from a speed difference between a target cruising vehicle speed and an actual vehicle speed. A requested cruise-control torque calculator obtains a requested cruise-control torque on the basis of the requested cruise-control horsepower and an engine rotation speed. A cruise-control accelerator-opening calculator sets a cruise-control accelerator opening by referring to an engine torque map in which a cruise-control accelerator-opening characteristic curve is set along an equal horsepower line on the basis of the requested cruise-control torque and the engine rotation speed. A target primary rotation-speed calculator sets a target primary rotation speed by referring to a shift-line map on the basis of the cruise-control accelerator opening and the actual vehicle speed. A shift controller obtains a target gear shift ratio on the basis of the target primary rotation speed and the actual vehicle speed so as to perform shift control.
