Abstract
A method for automatically parking a vehicle in a parking slot involves manually driving the vehicle into the parking slot in a training step, and thereafter automatically driving the vehicle into the parking slot in a replay step. Automatically driving the vehicle into the parking slot involves detecting information of features of the environment of the vehicle corresponding to the driven trajectory, matching feature descriptors of the detected features of the environment with feature descriptors stored in the digital map, and re-localizing the vehicle against the trajectory stored in the digital map in order to navigate the vehicle along the stored trajectory into the parking slot. Automatically driving the vehicle into the parking slot is repeated multiple times, and involves deleting a feature descriptor stored in the digital map if the number of matches does not exceed a threshold after a predefined number of repetitions.
