Abstract

The entertainment vehicle of the preferred embodiments includes a motor having an output torque, a gear selector that receives a gear selection amongst a number of simulated gear ratios, a sensor that senses the vehicle speed of the vehicle, and a processor that determines a simulated engine speed based on the gear selection and the sensed vehicle speed. The entertainment vehicle is preferably designed to simulate a vehicle with an internal combustion engine and multiple gear ratios. The entertainment vehicle, however, may be alternatively used in any suitable environment and for any suitable reason.
