Abstract: A technique controls regenerative braking to reduce skidding of a vehicle. Such a technique involves imparting rotation to an alternating current (AC) electric motor to move the vehicle to a first commanded vehicle speed; applying a regenerative braking power to the AC electric motor to bring the vehicle to a second commanded vehicle speed; while applying the regenerative braking power, adjusting the level of regenerative braking power applied to follow a predetermined speed reduction rate; while adjusting the level of regenerative braking power applied, provide a limit to the maximum level of regenerative braking power available; and while providing the limit to the maximum level of regenerative braking power available, adjusting the limit to the maximum level of regenerative braking power available based on a current speed of the vehicle.

Abstract: A technique provides power-limiting regenerative braking to a utility vehicle. The technique involves detecting that the utility vehicle is moving in a forward direction at a first speed. The technique further involves applying a first regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the first speed. The technique further involves detecting that the utility vehicle is moving in the forward direction at a second speed which is less than the first speed. The technique further involves applying a second regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the second speed. The second regenerative braking power level is lower than the first regenerative braking power level.

Abstract: A technique controls an electric brake of a vehicle. The technique involves continuously providing power to the electric brake of the vehicle to continuously disengage the electric brake and allow the vehicle to move. The technique further involves, while power is continuously provided to the electric brake and the vehicle is moving, sensing a fault condition. The technique further involves, in response to sensing the fault condition, providing electric pulses to the electric brake in place of continuously providing power to the electric brake, the electric pulses having varying pulse timing that controls braking of the vehicle. Accordingly, the vehicle is able to provide a more consistent braking response regardless of variations in certain factors such as brake calibration and/or current wear, the current weight in the vehicle, the current temperature, etc.
