A vehicle control device including an electronically controlled throttle device and configured to control a vehicle for supplying a hydraulic pressure to a friction engaging element of a transmission on the basis of a throttle valve opening controls a start timing of a supply of the hydraulic pressure to the friction engaging element on the basis of an accelerator pedal opening and the throttle valve opening if a shift lever is changed from an advance position to a reverse position or from the reverse position to the advance position.

Shift device for outboard motor

A shift device for an outboard motor includes a forward gear and a reverse gear; a clutch gear; a shift actuator configured to move between a neutral reference position where the clutch gear is disengaged from the forward gear and the reverse gear and an engagement reference position where the clutch gear is engaged with the forward gear or the reverse gear; and a control device configured to control a movement of the shift actuator. The control device is configured to set an intermediate target position, and to set a speed at which the shift actuator moves from the intermediate target position to the engagement reference position slower than a speed at which the shift actuator moves from the neutral reference position to the intermediate target position.

SYSTEM AND METHOD FOR SMOOTH TRANSMISSION ENGAGEMENT AND DISENGAGEMENT

Systems and methods for transitioning a hybrid vehicle from park or neutral to drive or reverse are presented. In one example, a requested engine speed is adjusted in response to a transmission disengaging indication and a transmission disengaging timer when a transmission is being disengaged from a gear. In another example, the requested engine speed is adjusted in response to a transmission engaging indication and a transmission engaging timer when the transmission is being engaged to a gear.

Control apparatus for vehicle

Torque reduction control is executed for temporarily reducing a torque capacity of a reaction engagement device during a transition of a shift. The reaction engagement device is maintained in an engaged state from before the shift to after the shift such that a predetermined rotating element in an automatic transmission bears a reaction caused by progress of the shift resulting from a change of an engaging-side engagement device into an engaged state. Therefore, without delaying a change of the engaging-side engagement device into the engaged state, transmission of torque that is generated as a result of rattling during a transition of a shift is reduced. Thus, in shift control over the automatic transmission, shock at the time of rattling is reduced while a stop of a shift due to a delay in change of the engaging-side engagement device into the engaged state is prevented.

Brake-dependent clutch holding pressure while transmission is in neutral

Systems and methods for performing a garage shift of an automatic transmission of a vehicle comprise maintaining a clutch at a first holding pressure while the transmission is in a neutral gear and a brake input signal satisfies a threshold and maintaining the clutch at a lower second holding pressure while the transmission is in the neutral gear and the brake input signal satisfies the threshold to mitigate or eliminate causing drive torque to be transferred from a torque generating system of the vehicle to its driveline via the transmission. When the brake input signal satisfies the threshold and a shift from the neutral gear to a non-neutral gear is requested, the garage shift is then executed.
