Claim 8:
9. A method, comprising:
receiving, by a processing circuit, an indication regarding at least one of a position of an accelerator of a vehicle and a speed of the vehicle, the position corresponding with an associated response of a prime mover of the vehicle, the associated response including at least one of a torque output and a power output of the prime mover;
detecting, by the processing circuit, an obstacle condition regarding a respective wheel of the vehicle encountering an obstacle (i) in response to determining that (a) the respective wheel is elevating or extending as a result of the respective wheel encountering the obstacle and (ii) while the speed of the vehicle is less than a predefined obstacle threshold speed level;
remapping, by the processing circuit, the associated response of the prime mover in response to (i) detection of the obstacle condition and (ii) the speed of the vehicle being less than the predefined obstacle threshold speed level such that the associated response of the prime mover increases for a respective position of the accelerator such that the respective wheel is capable of traversing the obstacle without requiring an operator increase in the position of the accelerator;
detecting, by the processing circuit, a reverse condition regarding the vehicle driving in reverse;
remapping, by the processing circuit, the associated response of the prime mover of the vehicle in response to the reverse condition such that the associated response of the prime mover is reduced for a respective position of the accelerator during the reverse condition relative to a forward operation condition of the vehicle, wherein the reduction in the associated response of the prime mover during the reverse condition provides reduced accelerator sensitivity over a range of travel of the accelerator while the vehicle is driving in reverse to increase accelerator resolution and improve speed control of the vehicle during reverse maneuvers;
detecting, by the processing circuit, a deceleration condition regarding a deceleration event for the vehicle; and
remapping, by the processing circuit, the associated response of the prime mover of the vehicle from following a normal response curve to following a deceleration response curve in response to the deceleration condition, wherein the prime mover is configured to provide a negative torque response and a positive torque response with a zero torque operating condition between the negative torque response and the positive torque response, and wherein (a) a first slope of the negative torque response for the deceleration response curve is greater than a second slope of the negative torque response for the normal response curve and (b) a first range of the zero torque operating condition for the deceleration response curve is smaller than a second range of the zero torque operating condition for the normal response curve, thereby reducing an overall range of the accelerator that is associated with the negative torque response and the zero torque operating condition such that, upon a subsequent acceleration following the deceleration event in response to the accelerator being engaged by the operator and in accordance with the positive torque response of the prime mover, an output of the prime mover to accelerate the vehicle activates at a relatively lesser amount of depression of the accelerator from a non-depressed state of the accelerator than prior to the deceleration event.
