摘要:
A vehicle includes a cruise control section arranged and programmed to perform control to maintain the vehicle speed at a prescribed vehicle speed while a clutch is engaged. A clutch actuator control section performs control to disengage the clutch when the value of a parameter becomes equal to or lower than a first threshold value, in the case where the cruise control section is determined to not be performing the control to maintain the vehicle speed at a prescribed vehicle speed; and performs the control to disengage the clutch when the value of the parameter becomes equal to or lower than a second threshold value, which is lower than the first threshold value, in the case where the cruise control section is determined to be performing the control to maintain the vehicle speed at a prescribed vehicle speed.

To provide a transmission capable of prompt shifting and modification of bumping between dogs. When a movable gear (7) moves from a state in which the dogs (52, 72) of a first stationary gear (5) and of the movable gear (7) are engaged with each other, toward a second stationary gear (6), a force in a direction opposite from a direction toward the second stationary gear (6) is applied to the movable gear (7) after the engagement between the dogs (52, 72) of the first stationary gear (5) and of the movable gear (7) is released, until the movable gear (7) reaches a position where the dogs (74, 64) of the movable gear (7) and of the second stationary gear (6) contact each other.

A vehicle includes a friction clutch located between an engine and a driving wheel; a clutch actuator arranged to disengage and engage the friction clutch; a clutch actuator control section arranged and programmed to control the clutch actuator; a slip detection section arranged to detect a slip of the driving wheel; and an engine control section arranged and programmed to decrease an output of the engine when the slip of the driving wheel is detected by the slip detection section. When the friction clutch is in a half clutch state and the slip of the driving wheel is detected at the time of starting of the vehicle, the clutch actuator control section controls the clutch actuator so as to change a pushing force of the friction clutch and thus to keep the rotation speed of the engine at a fixed level.

To provide a transmission capable of prompt shifting and modification of bumping between dogs. Speed information indicating the moving speed of a movable gear (7) is obtained, and when the moving speed of the movable gear (7) moving toward the second stationary gear (6) is larger than a predetermined value, an increased force toward the first stationary gear (5) is applied to the movable gear (7), and when the moving speed is smaller than the predetermined value, an increased force toward the second stationary gear (6) is applied to the movable gear (7).
