Abstract: A drivetrain has at least one electric drive machine configured for driving a motor vehicle, a drivable rear motor vehicle axle for transmitting drive forces of the electric drive machine to a roadway surface, and a vehicle transmission which has at least one transmission ratio stage and which is configured for transmitting drive forces in the direction of the drivable rear motor vehicle axle. The transmission ratio stage can, in at least one operating mode of the drivetrain, be engaged by a transmission control unit. The vehicle transmission can, from the transmission ratio stage, be shifted by the transmission control unit into a neutral position in which a transmission output shaft is freely rotatable relative to a transmission input shaft. For control of the electric drive machine, an electric motor control unit is provided, wherein the electric drive machine is, by way of the electric motor control unit, operable at least in a motor operating mode and in a neutral mode, in which the electric drive machine is rotatable in a manner free from torque. The electric motor control unit and the transmission control unit are connected to one another by at least two control lines configured for transmitting control commands between the control units. A control command can be transmitted by the electric motor control unit via at least one of the two control lines to the transmission control unit, such that the transmission control unit sets the vehicle transmission into the neutral position.

Abstract: A method of controlling a hybrid electric vehicle including an engine and a first motor connected to main drive wheels and a second motor connected to auxiliary drive wheels includes determining a required torque, in response to a predetermined condition being satisfied, determining a first torque that the second motor is to continuously output based on the required torque and a vehicle speed and determining a second torque that the second motor is to discontinuously output in order to compensate for acceleration loss in a situation in which the acceleration loss occurs based on a state of an engine clutch disposed between the engine and the first motor, a state of a transmission, or the required torque, and determining a final torque of the second motor based on the first and second torques.

Abstract: A braking/driving force control system, during control for maintaining a target vehicle speed, performs fuel cut and then, when a required braking/driving force for maintaining the target vehicle speed reduces, makes a downshift while fuel cut is continued. The braking/driving force control system causes a brake to generate a braking force such that the sum of a braking/driving force that a powertrain generates and the braking force that the brake generates agrees with the required braking/driving force. Thus, good fuel efficiency and riding comfort are obtained.

Abstract: A shift control device to be applied to a vehicle provided with an automatic transmission includes a detector and a shift mode control processor. The detector detects that the vehicle has passed through a tollgate through which the vehicle is able to pass without stopping. The shift mode control processor switches a shift mode of the vehicle from a first shift mode to a second shift mode the shift mode of the vehicle upon passing through the tollgate is the first shift mode and a predetermined condition regarding one or both of a speed of the vehicle and an accelerator opening degree of the vehicle is satisfied after the vehicle passes through the tollgate. In the first shift mode, a shift operation is performable by a driver, and in the second shift mode, a shift operation is performable by the automatic transmission.

Abstract: In a driven state phase, target input torque is limited to a first limit value, whereas in a backlash-elimination state phase, the target input torque is limited to a second limit value and target engine torque and torque of a motor-generator are controlled according to the target input torque. In the backlash-elimination state phase, the target input torque is limited to the second limit value that is suitable for mitigating rattling shock, so that rattling shock can be appropriately mitigated. Meanwhile, in the driven state phase, the target input torque is limited to the relatively high first limit value, so that an MG rotation speed can be quickly increased to eliminate a rotational difference, which enhances the responsiveness of driving power up to when required driving power is obtained after elimination of the backlash.

Abstract: A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller which executes, during deceleration of an automobile, a gear-shifting control of changing a shift stage of the automatic transmission by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft and a regeneration control of performing regeneration by at least one of distributing a braking force by the friction brake system and imparting a regenerative braking torque to rear wheels by causing the motor to perform a regeneration operation. The controller executes a first coordinated gear-shifting control of reducing hydraulic pressure in the friction brake system and, at the same time, changing the shift stage while continuing the regeneration operation during brake regeneration and executes a second coordinated gear-shifting control of changing the shift stage after increasing an input torque during non-brake regeneration.
