Abstract
A utility vehicle is configured for independently controlling torque at each of the ground-engaging members.
Claims23
A utility vehicle, comprising:
- a first front ground-engaging member;
- a first axle operably coupled to the first front ground-engaging member;
- a second front ground-engaging member;
- a second axle operably coupled to the second front ground-engaging member and being axially aligned with the first axle;
- at least one rear ground-engaging member;
- a first torque altering unit operably coupled to at least one of the first front ground-engaging member, the second front ground-engaging member, or the at least one rear ground-engaging member;
- a second torque altering unit operably coupled to the at least one rear ground-engaging member and defined as one of an open differential, a lockable differential, or an active torque differential;
- and
- a control system configured to independently control torque output at each of the first front ground-engaging member, the second front ground-engaging member, and the at least one rear ground-engaging member.

A method of controlling torque for an off-road utility vehicle, comprising:
- controlling torque to a first ground-engaging member of the utility vehicle;
- controlling torque to a second ground-engaging member of the utility vehicle simultaneously with and independently of controlling torque to the first ground-engaging member;
- controlling torque to a third ground-engaging member of the utility vehicle independently of controlling torque to the first and second ground-engaging members;
- and
- detecting a pitch of the vehicle and controlling torque to the first ground-engaging member based upon the detected pitch.
2 more elements
A driveline assembly for a utility vehicle, comprising:
- a front differential configured to be operably coupled to at least one front ground-engaging member of the utility vehicle;
- a rear differential configured to be operably coupled to at least one rear ground-engaging member of the utility vehicle;
- and
- a control system operably coupled to the front and rear differentials, wherein the control system is configured to control distribution of torque to each of front and rear ground-engaging members, in combination with braking of at least one of the at least one front-ground-engaging member and the at least one rear ground-engaging member, to affect steering of the utility vehicle.
1 more element
A method of controlling torque for an off-road vehicle, comprising:
- controlling torque to a first ground-engaging member of the utility vehicle by providing a braking input at the first ground-engaging member;
- controlling torque to a second ground-engaging member of the utility vehicle simultaneously with and independently of controlling torque to the first ground-engaging member;
- controlling torque to a third ground-engaging member of the utility vehicle independently of controlling torque to the first and second ground-engaging members:
- and
- controlling the distribution of torque to each of the first ground-engaging member, second ground-engaging member and third ground-engaging member based upon at least one of steering angle data, yaw rate data, or wheel speed data.
