Abstract: A control apparatus for a vehicle that includes: a drive wheel; an engine; a gear-type power transmission device disposed between the engine and the drive wheel; and a rotary electric machine connected to the gear-type power transmission device in a power transmittable manner. The rotary electric machine is configured to apply a pressing torque in order to suppress rattle noise caused by play between gears of the gear-type power transmission device. The control apparatus is configured to detect an engine torque that is a torque of the engine, and to control the pressing torque based on the detected engine torque.

Abstract: A hybrid vehicle includes: an engine; first and second rotating electric machines; a connection/disconnection mechanism; a power storage device; and a control device. Further, when an acceleration request occurs during EV traveling mode, the control device controls, when determining that a predetermined acceleration smaller than a requested acceleration and corresponding to a vehicle speed cannot be generated by torque output by the second rotating electric machine, the torque output by the second rotating electric machine so as to generate an acceleration less than the predetermined acceleration while controlling the torque by the engine and torque by the first rotating electric machine, and when determining that the predetermined acceleration cannot be generated by the torque output by the second rotating electric machine, controls the torque output by the second rotating electric machine so as to generate the acceleration equal to or greater than the predetermined acceleration.

Abstract: A method and a system for a vehicle comprising: one or more power sources including at least one electrical machine; and a drivetrain for transferring torque between the one or more power sources and at least one drive wheel of the vehicle. The method comprises: controlling, when no positive drive torque (Tdrive) is transferred from the drivetrain to the at least one drive wheel, the at least one electrical machine to provide a backlash torque (Tbacklash) to the drivetrain, the backlash torque (Tbacklash) having a controlled value for turning the drivetrain if there is a backlash present in the drivetrain.

Abstract: Methods and systems are provided for a vehicle. In one example, a method for the vehicle includes adjusting an output torque of an electric machine to produce a desired vehicle speed and direction of propulsion while operating an auxiliary load powered via the transmission. The output torque may be adjusted while disengaging clutches of a transmission or a service brake to mechanically unlock an output shaft of the transmission. The first electric machine may be operated in a speed control to learn an amount to torque to hold the vehicle speed at zero and the amount of learned torque may be superimposed with an amount of requested torque upon vehicle launch.

Abstract: A control system for a hybrid vehicle configured to reduce electricity consumption by a motor in a condition where a maximum output torque of an engine is restricted. A controller is configured to: calculate a current maximum torque of the engine when increasing a speed of the engine to achieve an acceleration demand; determine whether the current maximum torque of the engine is less than an inertia torque required to increase the speed of the engine; and adjust the reaction torque of the first motor to a value less than a predetermined value, if the current maximum torque of the engine is less than the inertia torque required to increase the speed of the engine.

Abstract: A system for a vehicle includes a powertrain configured to propel the vehicle, and a controller configured to, during a first lap of the vehicle around a track, identify a portion of the track corresponding to a correlation of velocity, throttle position, and steering angle values indicative of a maximum power threshold, and, during a second lap, responsive to approaching the portion, limit power output by the powertrain causing temperature of the powertrain to fall and, upon entering the portion, increase power output to the maximum power threshold causing the temperature to rise, such that a difference in temperature between initiation of the limiting and exiting of the portion approaches zero.

Abstract: A vehicle control device that controls a vehicle is configured to execute rotation speed control when the vehicle is in series traveling, in which a rotation speed of the internal combustion engine is increased to a first rotation speed in accordance with an increase in a speed of the vehicle, and when the rotation speed of the internal combustion engine reaches the first rotation speed, the rotation speed of the internal combustion engine is decreased to a second rotation speed lower than the first rotation speed; and restrict execution of the rotation speed control when receiving a predetermined operation.

Abstract: A method for operating a drive unit for a motor vehicle. The drive unit has at least one internal combustion engine, an electric machine which is or may be drivingly coupled to the internal combustion engine, and a start-up clutch, via which the internal combustion engine and the electric machine are drivingly connected to an output shaft of the drive unit. In a start-up operation mode of the drive unit, the internal combustion engine is operated without ignition when the start-up clutch is open, and is cranked by the electric machine to a start-up speed, which is greater than an idle speed of the internal combustion engine. The internal combustion engine is ignition-operated and the start-up clutch is closed upon reaching the start-up speed. The invention further relates to a drive unit for a motor vehicle.

Abstract: Methods and systems are provided for operating a hybrid vehicle during launch conditions from rest. In one example, a threshold speed below which a clutch is closed during a vehicle launch is adjusted so that driver demand wheel torque is held constant for a constant accelerator pedal position until the clutch is closed.
