Embodiment Construction
[0069] The invention relates to a real-time estimation method for the lateral motion state of a preceding vehicle in consideration of random measurement time lag, in particular to a rolling time-domain estimation method for the lateral motion state based on a multi-rate vehicle motion model. More specifically, with the continuous improvement of vehicle intelligence, it is necessary to obtain real-time acquisition of the movement status of surrounding vehicles, especially the vehicle in front, so as to provide necessary information support for the vehicle's decision-making, planning and control system.
[0070] In the car-following situation, the advanced driving assistance system or automatic driving system of the vehicle needs to obtain the lateral motion state of the vehicle in front. The present invention designs a method for the lateral motion of the vehicle in front under the condition of considering the measurement time lag. Real-time estimation method of motion state. I...
