The system includes a plurality of wheel rotation sensors, a grade sensor, an acceleration sensor, an accelerator pedal deflection sensor, a brake pedal deflection sensor, and a processor. The processor is configured to compute a linear wheel speed, an upper limit of vehicle speed, and a lower limit of vehicle speed, based on the grade information, the pedal deflection information, and the acceleration, and then compute an estimated speed of the vehicle based on the linear wheel speed, the upper limit of vehicle speed, and the lower limit of vehicle speed.",
