Regenerative control system for an electric vehicle
First Claim
1. An electric vehicle, comprising:
- a frame having front and rear ends;
a plurality of ground engaging members supporting the frame, the plurality of ground engaging members including a first group positioned adjacent the frame front end and a second group positioned adjacent the frame rear end;
an electric motor supported by the frame;
a front drive system supported by the frame and positioned adjacent the frame front end, the front drive system operatively coupled to the electric motor and to the first group of ground engaging members, the electric motor providing power to at least one of the first group of ground engaging members;
a rear drive system supported by the frame and positioned adjacent the frame rear end, the rear drive system being operatively coupled to the electric motor and to the second group of ground engaging members, the electric motor providing power to at least one of the second group of ground engaging members;
a plurality of batteries supported by the frame;
an electronic controller which controls a provision of power from the plurality of batteries to the electric motor; and
a drive mode input operatively coupled to the electronic controller, the electronic controller operating the electric vehicle in one of a plurality of drive modes based on the drive mode input, wherein in a first drive mode the electronic controller specifies a first amount of motor braking to be applied by the electric motor and in a second drive mode the electronic controller specifies a second amount of motor braking to be applied by the electric motor, the second amount differing from the first amount.

Abstract
An electric vehicle is disclosed having a frame, a plurality of ground engaging members, an electric motor, a front drive system, and a rear drive system. The electric motor is configured to provide power to at least a portion of the ground engaging members. The vehicle also comprises a plurality of batteries, an electronic controller, and a drive mode input. The drive mode input is operatively coupled to the electronic controller. The electronic controller operates the electric vehicle in one of a plurality of drive modes based on the drive mode input. In a first drive mode, the electronic controller specifies a first amount of motor braking to be applied by the electric motor, and in a second drive mode, the electronic controller specifies a second amount of motor braking to be applied by the electric motor. The second amount differs from the first amount.
