An electronic throttle controller adjusts vehicle acceleration based on accelerator pedal movement. The controller compares a rate of change of a pedal voltage with a rate of change of a filtered pedal voltage. The filtered pedal voltage depends on filter alpha values that vary as a function of engine speed divided by vehicle speed. If the rate of change of the pedal voltage exceeds the rate of change of the filtered pedal voltage by a threshold, the controller selects a performance mode. The performance mode determines how the controller adjusts a transmission ratio and power request damping. Additionally, the controller adjusts a duration of the performance mode based on an acceleration condition. The acceleration condition is indicative of whether engine speed, vehicle speed, and pedal position are constant.
