Abstract
A control system for a vehicle, the control system includes a selectable one-way clutch, a motor, and an electronic control unit. The electronic control unit is configured to (i) execute rotation control to control the motor such that negative differential rotation changes into positive differential rotation when the selectable one-way clutch is switched from a disengaged state to an engaged state while differential rotation of the selectable one-way clutch is negative and (ii) initiate engagement control by a switching mechanism such that a projecting operation of the selectable one-way clutch is completed while the differential rotation is negative.
Claims8
A control system for a vehicle, the control system comprising:
- a selectable one-way clutch including
- a first clutch member,
- a second clutch member, the first clutch member and the second clutch member are rotatable relative to each other,
- a strut configured to be operated such that a part of the strut projects from the first clutch member to the second clutch member,
- a switching mechanism configured to selectively set a first state or a second state, the first state being a state in which a projecting operation is permitted, the projecting operation being an operation in which the part of the strut projects from the first clutch member to the second clutch member, and the second state being a state in which the projecting operation is inhibited,
- wherein, the first state is a state in which the part of the strut projects from the first clutch member to the second clutch member and engages with a part of the second clutch member so that a relative rotation between the first and second clutch members in one of a positive rotational direction or a reverse rotational direction of the selectable one-way clutch is restricted, and the second state is a state in which the operation of the part of the strut that projects from the first clutch member to the second clutch member is inhibited so that the relative rotation in both of the positive rotational direction and the reverse rotational direction of the selectable one-way clutch is permitted;
- a motor configured to control a rotational speed of one of the first and second clutch members;
- and
- an electronic control unit configured to
- (i) execute rotation control to control the motor such that a negative differential rotation changes into a positive differential rotation when the selectable one-way clutch is switched from the second state to the first state while the differential rotation is negative, and
- (ii) initiate engagement control to set the first state by the switching mechanism such that the projecting operation is completed while the differential rotation is negative.
