This paper tests the effectiveness of closed-loop brake control to reduce vehicle off-tracking arising from overspeeding in curves. When a driver enters a curve too fast given the available friction, the aim is to use electronic brake control to reduce speed and increase path curvature to complete the turn. Previously it has been found that coordinated four wheel braking referenced to an inertially fixed vehicle mass center acceleration (PPR) is an optimal control strategy. The present work introduces the effect of driver-vehicle interaction, using simulation and track experiments. It is confirmed that PPR effectiveness is not disrupted by typical steering corrections from the driver. PPR is found to offer significant path following improvements compared with other brake control strategies.
