Abstract
A vehicle has a frame; a motor connected to the frame; a rear drivetrain connected to the frame; a front drivetrain connected to the frame and having a lockable front differential; a manual override control; and a controller operatively connected to the lockable front differential and to the manual override control. The controller is adapted for controlling the motor to limit a speed of the motor when the front differential is locked and the manual override control is not activated.
Claims20
A vehicle, comprising:
- a frame;
- a motor connected to the frame;
- a rear drivetrain connected to the frame and operatively connected to the motor;
- a front drivetrain connected to the frame and operatively connected to the motor, the front drivetrain comprising a lockable front differential;
- a controller operatively connected to the lockable front differential;
- and
- a manual override control operatively connected to the controller,
- the controller being adapted for controlling the motor to limit a speed of the motor in response to the front differential being locked and the manual override control not being activated,
- the controller being adapted for disabling the limit to the speed of the motor in response to the manual override control being activated.

A vehicle, comprising:
- a frame;
- a motor connected to the frame;
- a rear drivetrain connected to the frame and operatively connected to the motor;
- a front drivetrain connected to the frame and operatively connected to the motor, the front drivetrain comprising a lockable front differential;
- a controller operatively connected to the lockable front differential;
- and
- a manual override control operatively connected to the controller,
- the controller being adapted for controlling the motor to limit a speed to a first speed in response to the front differential being locked and the manual override control not being activated, the speed being one of a motor speed and a vehicle speed,
- the controller being further adapted for controlling the motor to permit the speed to reach a second speed in response to the front differential being locked and the manual override control being activated, the second speed being greater than the first speed.
