Estimations of Axle Output Torque and Disturbance Load Torque for Automobile by DBW.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1999
Recently, the vehicle which is adopting an electronically controlled throttle valve (ECTV) is controlled by DBW (Drive by wire) for the purpose of improving the automobiles performance. One of them is an optionally tuning for the accelerator pedal sensitivity, and it needs axle output torque as the feedback signal.
