Abstract
A vehicle includes an anti-lock braking system (ABS), a stability control system (SCS), and an electronic locking differential. A controller of the vehicle is programmed to unlock the differential in response to activation of the ABS or the SCS. The controller is further programmed to, responsive to the deactivation of the activated one of the ABS and the SCS, inhibit locking of the differential for a predefined period of time.
Claims20
A vehicle comprising:
- an anti-lock braking system (ABS);
- a stability control system (SCS);
- an electronic locking differential;
- and
- a controller programmed to:
- unlock the differential in response to activation of the ABS or the SCS, and
- responsive to deactivation of the activated one of the ABS and the SCS, inhibit locking of the differential for a predefined period of time.

A vehicle comprising:
- an anti-lock braking system (ABS);
- a stability control system (SCS);
- a locking differential including an electronically controlled locker configured to lock the differential;
- and
- a controller programmed to,
- energize the locker to lock the differential in response to (i) vehicle speed being less than a threshold, (ii) accelerator-pedal position being less than a threshold, and (iii) a steering angle being less than a threshold,
- de-energize the locker to unlock the differential in response to activation of at least one of the ABS and the SCS, and
- responsive to deactivation of the activated one of the ABS and the SCS, inhibiting energization of the locker for a predefined period of time.
5 more elements
A method of controlling an electronic locking differential, comprising:
- locking the differential in response to engagement conditions being present;
- unlocking the differential in response to activation of at least one of an anti-lock braking system (ABS) and a stability control system (SCS);
- and
- inhibiting locking of the differential for a predefined period of time that starts in response to deactivation of the activated one of the ABS and the SCS.
