Abstract
Methods and apparatus for adjusting at least one of the motors in an electrically driven vehicle having a first motor for controlling a first wheel and a second motor for controlling a second wheel are disclosed. The method is performed in response to input from a user control that enables an operator of the vehicle to steer the vehicle. It is determined from one or more conditions whether the operator of the vehicle is attempting to drive the vehicle straight on approximately level ground. When it is determined from the one or more conditions that the operator of the vehicle is attempting to drive the vehicle approximately straight on approximately level ground, it is then determined whether to adjust one of the motors based upon the input from the operator of the vehicle to the user control. When it is determined that adjustment is appropriate, the appropriate motor is adjusted.
