This paper considers the problem of controlling an
autonomous vehicle to arrive at a specific position on a
road at a given time and velocity. This ability is
particularly useful for a recently introduced autonomous
intersection management protocol, called AIM, which has
been shown to lead to lower delays than traffic signals
and stop signs. Specifically, we introduce a setpoint
scheduling algorithm for generating setpoints for the
PID controllers for the brake and throttle actuators of
an autonomous vehicle. The algorithm constructs a
feasible setpoint schedule such that the vehicle arrives
at the position at the correct time and velocity. Our
experimental results show that the algorithm outperforms
a heuristic-based setpoint scheduler that does not
provide any guarantee about the arrival time and
velocity.
