Figure 17-3. As the accelerator pedal pressure raises, i.e., large positive, the
vehicle starts accelerating. On the other hand, as the brake pedal pressure
increases, the vehicle slows down with a negative acceleration. Since the
drivers can only apply pressure to either the accelerator pedal or the brake
pedal, i.e., both feet are not used at the same time, these two signals are
mutually exclusive, which is explicitly seen in the plots. By integrating these
facts and the significantly different driving tendencies among the collected
data, it is quite possible to extract the individuality of drivers using the linear
prediction theory.
