Electronic locking differential
First Claim
Patent Images
1. A vehicle comprising:
- a differential including an electronic locker; and
a controller programmed to, when in differential-lock mode,engage the locker responsive to vehicle speed being less than a speed threshold and a parameter indicative of steering angle being less than a threshold,disengage the locker responsive to vehicle speed exceeding the speed threshold,prevent automatic re-engagement of the locker responsive to the parameter exceeding the threshold, andissue a driver alert, requesting straightening of the steering shaft, in response to the parameter exceeding the threshold.

Abstract
A vehicle includes a differential having an electronic locker and a controller. The controller is programmed to, when in differential-lock mode, engage the locker responsive to vehicle speed being less than a speed threshold and a steering angle being less than a threshold, disengage the locker responsive to vehicle speed exceeding the speed threshold, and prevent automatic re-engagement of the locker responsive to the steering angle exceeding the threshold.

7. A vehicle comprising:
-
a differential including an electronic locker; and a controller programmed to, responsive to the locker being engaged and vehicle speed exceeding a speed threshold, command disengagement of the locker, and responsive to the locker being disengaged, differential-lock mode being requested, vehicle speed being below the speed threshold, and a parameter indicative of a steering angle exceeding a threshold, (i) prevent automatic re-engagement of the locker and (ii) issue a driver alert. - View Dependent Claims (8, 9, 10, 11, 12, 13)

15. A method of controlling an electronic-locking differential comprising:
-
disengaging the electronic-locking differential responsive to the differential being engaged and vehicle speed exceeding a speed threshold; preventing automatic re-engagement of the differential responsive to the differential being disengaged, differential-lock mode being requested, vehicle speed being below the speed threshold, and a parameter indicative of steering angle exceeding a threshold; and displaying an alert to a driver in response to the parameter exceeding the threshold and the differential-lock mode being requested. - View Dependent Claims (16)
