Dynamic parking using an assistance system

A method to park a vehicle in a parking space using a parking assistant is provided. The course of a parking maneuver is dynamically adapted to boundaries of the parking space that are changed during the parking maneuver by determining whether and in which direction the boundaries of the parking space change during the parking maneuver. An originally determined first trajectory is replaced by a second trajectory that is adapted to changed boundaries of the parking space and along which the parking maneuver is continued.

The disclosure relates to assessing and responding to wheel slippage and estimating road friction for a road surface. For instance, a vehicle may be controlled in an autonomous driving mode in order to follow a trajectory. A wheel of the vehicle may be determined to be slipping such that the vehicle has limited steering control. In response to determining that the wheel is slipping, steering of one or more wheels may be controlled in order to orient the one or more wheels towards the trajectory in order to allow the vehicle to proceed towards the trajectory when the wheel is no longer slipping. In addition, the road friction may be estimated based on the determination that the wheel is slipping. The vehicle may be controlled in the autonomous driving mode based on the estimated road friction.
