Sys., Meas., Control. 2017;139(3): doi: / Figure Legend: Optimal torque (T) through the maneuver for the US and OS vehicles. The torque is positive (accelerating) if the line is above road level and negative (braking) when the line is below road level. Both vehicles accelerate in the first part of the maneuver, then brake at corner entry and accelerate at the exit. The vertical lines correspond to data at time intervals of 0.4 s. The triangles and circles plotted at road level correspond to the three phases of the maneuver: braking on entry, transition from braking to accelerating at midcorner, and maximum drive torque at exit.

The steering angle for the US vehicle is positive through most of the corner while it is positive at the beginning of the corner for the OS vehicle and negative (countersteering) toward the exit.
