  • Publication number: 20230089521
    Abstract: An example system includes a roadside apparatus and an in-vehicle device for position-based parking of a vehicle, for example, in environments with weak GPS signals. The roadside apparatus determines a first posture data of a vehicle that includes a relative position and an orientation of the vehicle. The relative position is with respect to a predetermined location associated with the roadside apparatus. The roadside apparatus transmits the first posture data, and the in-vehicle device receives the first posture data. The in-vehicle device dynamically evaluates a predetermined rule with the first posture data. The predetermined rule defines a target posture data with respect to both relative position and orientation. The in-vehicle device controls, in response to the predetermined rule failing to be satisfied, the vehicle to perform a posture adjustment operation based on posture adjustment data determined from a difference between the target posture data and the first posture data.
