1. 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 being configured to make relative rotation 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 an projecting operation is permitted, the projecting operation being an operation that 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,the selectable one-way clutch being configured to be switched between an engaged state and a disengaged state, the engaged state being a state in which the relative rotation in one of a positive rotational direction and a reverse rotational direction of the selectable one-way clutch is restricted with the first state in which the part of the strut projects from the first clutch member to the second clutch member and the part of the strut engages with a part of the second clutch member, and the disengaged state being a state in which the relative rotations in both of the positive rotational direction and the reverse rotational direction of the selectable one-way clutch are permitted with the second state in which the operation of the part of the strut to be projected from the first clutch member to the second clutch member is inhibited; a motor configured to control a rotational speed of one of a first rotary member and a second rotary member, the selectable one-way clutch being configured such that differential rotation occurs by controlling the rotational speed by the motor, the differential rotation including positive differential rotation and negative differential rotation, the positive differential rotation being a relative rotation in a direction in which the relative rotation is restricted when the selectable one-way clutch is in the engaged state, and the negative differential rotation being a relative rotation in a direction in which the relative rotation is permitted when the selectable one-way clutch is in the engaged state; and an electronic control unit configured to
(i) execute rotation control to control the motor such that the negative differential rotation changes into the positive differential rotation when the selectable one-way clutch is switched from the disengaged state to the engaged 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. |
