Disclosed is a vehicle road load compensation system that includes an accelerator pedal, a throttle, a transmission wherein a vehicle torque is generated proportional to the transmission gear and the motor power, and a control unit disposed within the vehicle and configured to receive real-time sensor data relating to the road load of the vehicle. The control unit includes a real-time throttle map relating the accelerator pedal position to the throttle position, such that a given accelerator pedal position directs a corresponding target throttle position. The control unit also includes a real-time shift map relating a desired transmission gear to a current transmission gear, vehicle speed, and throttle position. In response to the sensor data, the control unit updates the throttle map and shift map such that the vehicle torque is altered based on the road load of the vehicle. The controller may also update a real-time torque converter lockup map.
