A controller in a host vehicle 30 includes a processor and a memory storing processor-executable instructions. The processor is programmed to calculate an error bound for confidence intervals of a predicted position at a future time of a target vehicle 32 relative laterally to a current position and orientation of the host vehicle at a current time based on a current position and velocity of the target vehicle and the future time. The error may be based on a current velocity and yaw rate of the host vehicle and a heading angle between the host and target. The predicted position may be calculated using coefficients from a quadratic polynomial method. The braking or steering system of the host vehicle may be controlled to evade the target vehicle based on the predicted position and error bound. An error metric may be calculated based on a difference between the predicted future position and an actual future position of the target vehicle, which may be used to determine a quality measure.
