Abstract
A vehicle control system that ensures a sufficient distance to empty in the event of a failure of a clutch for changing an operating mode of a vehicle. The control system is configured to: determine a reduction in performance of the clutch based on a value of a parameter for determining a performance of the clutch; and select the operating mode in which a distance to empty is longer and inhibit to actuate the engagement device, when a reduction in performance of the engagement device is determined.
Claims13
A vehicle control system that is applied to a vehicle comprising:
- a plurality of pairs of rotary members;
- an engagement device that selectively connects any one of the pairs of rotary members;
- and
- an actuator that reciprocates one of rotary members of the one of the pairs of rotary members toward and away from the other one of the rotary members of the one of the pairs of rotary members,
- wherein an operating mode of the vehicle includes at least a first mode and a second mode,
- the operating mode of the vehicle is shifted between the first mode and the second mode by manipulating the engagement device,
- the vehicle control system comprising:
- a controller that controls at least the engagement device,
- the controller is configured to
- determine a reduction in performance of the engagement device based on a value of a parameter for determining the performance of the engagement device, and
- select the operating mode in which a distance to empty is longer from the first mode and the second mode, and inhibit to actuate the engagement device, when a reduction in the performance of the engagement device is determined.
