A method to control a road vehicle provided with a clutch, which connects an internal combustion engine to drive wheels and is arranged upstream of a servo-assisted transmission; the control method comprises the steps of: checking whether the tyres of the drive wheels are close to a grip limit; and opening the clutch so that the clutch transmits a torque to the drive wheels with a slip of the clutch that is constant and other than zero when the tyres of the drive wheels are close to the grip limit.

A method to control a road vehicle for the execution of a standing start; the control method comprises the steps of: engaging a gear in a transmission while a corresponding clutch is open; progressively closing the clutch causing the clutch to transmit a torque that causes the rotation of at least a pair of drive wheels; determining a target slip of the drive wheels; cyclically determining a real slip of the of the drive wheels; and continuously modulating the torque transmitted by the clutch during the closing of the clutch based of a difference between the target slip of the drive wheels and the real slip of the of the drive wheels.

An actuator module for a driveline assembly includes, among other things, a cover housing and a fork driving unit supported by the cover housing. The fork driving unit includes a fork driver and a pusher assembly coupled to the fork driver by spaced apart pusher ends. The fork driving unit also includes a drive assembly carried by the pusher assembly to translate the fork driver relative to the cover housing. The fork driving unit further includes a spring that biases the pusher assembly and fork driver to a neutral position.

A shift range control device switches a shift range by controlling a drive of a motor in which a rotor rotates by energizing a motor winding. An angle calculation unit calculates a motor angle based on a signal from a rotation angle sensor that detects a rotation position of the rotor. An energization control unit drives the rotor so that the motor angle becomes a target angle according to the target shift range, and stops the rotor at a position where the motor angle becomes the target angle, by controlling the energization of the motor winding. A zero point estimation unit estimates a speed 0 point, which is a timing at which a rotational speed of the vibrating rotor becomes 0 during the stop control for stopping the rotor. The energization control unit switches a current control at the estimated speed 0 point.

A transmission system for a vehicle having a belt drive transmission. The belt drive has an adjustable input and output ratio, where the output of the belt drive is provided as a first input to a differential coupling. A further rotating connection is provided as a second input to the differential coupling, so that the output of the differential coupling is arranged as the output of the transmission system. Accordingly, the transmission output is based on the aggregate sum of the rotation of the first and second inputs to the differential coupling, wherein adjustment of the input and output ratio of the belt drive allows for a continuously variable transmission system.

A shift range control device switches a shift range by controlling drive of a motor. An angle calculation unit calculates a motor angle based on a signal from a rotation angle sensor that detects a rotation position of the motor. A drive control unit drives the motor so that the motor angle becomes a target angle according to the target shift range, and stops a rotor by a fixed phase energization, when the motor angle reaches a target angle. When the rotor vibrates with respect to stop position, the drive control unit maintains a state in which a brake torque, which is the torque generated when moving away from center of vibration, is larger than an acceleration torque, which is the torque generated when moving toward the center of vibration, and reduces the current that energizes the motor based on a difference between the brake torque and the acceleration torque.

A working fluid supply device is provided with: a first oil pump and a second oil pump driven by an engine; a third oil pump driven by an electric motor; a first unloading valve configured to shift the second oil pump to a no-load operation state; and a controller configured to control a supply state of working oil to an automatic transmission. The controller sets the supply state to a supply state selected from: a first supply state in which the working oil is supplied only from the first oil pump; a second supply state in which the working oil is supplied from the first oil pump and the third oil pump; a third supply state in which the working oil is supplied from the first oil pump and the second oil pump; and a fourth supply state in which the working oil is supplied from the first oil pump, the second oil pump, and the third oil pump.
