Original Abstract Submitted
A motion plan safety analysis is performed by processing vehicle sensor signals to generate a motion plan which includes a reference trajectory value, by processing the reference trajectory value at a first MPC to generate a first current setpoint and a first plurality of future setpoints, by processing the first plurality of future setpoints at a second MPC to generate a second plurality of future setpoints, by processing the second plurality of future setpoints at the first MPC to generate a first plurality of predicted trajectory states, by processing the first plurality of future setpoints at the second MPC to generate a second plurality of predicted trajectory states, by evaluating the predicted trajectory states to generate a predetermined safety reaction for the vehicle, and by choosing between the first and second current setpoints based on the safety reaction to provide a safest setpoint to a vehicle actuator in the vehicle.
