TL;DR: In this paper, a new approach to estimate vehicle tire forces and road maximum adherence is presented, which is not an asymptotic observer based estimation, but a combination of elementary diagnosis tools and new algebraic techniques for filtering and estimating derivatives of noisy signals.

TL;DR: In this paper, the authors proposed a path planning method based on a geometric approach such as minimal turning radii, which can be determined by the geometry of a vehicle and its maximum steering angle.

TL;DR: A combined longitudinal and lateral vehicle control is presented that employs flatness-based control and new algebraic estimation techniques for the numerical differentiation of noisy signals for automatic path-tracking via vehicle steering angle and driving/braking wheel torque.
Abstract: A combined longitudinal and lateral vehicle control is presented. It employs flatness-based control and new algebraic estimation techniques for the numerical differentiation of noisy signals. This nonlinear control is designed for automatic path-tracking via vehicle steering angle and driving/braking wheel torque. It combines the control of the lateral and longitudinal movements in order to ensure an accurate tracking of straight or curved trajectories. It can also be used to perform a combined lane-keeping and steering control during critical driving situations such as obstacle avoidance, stop-and-go control, lane-change maneuvers or any other maneuvers. Promising results have been obtained using the noisy experimental data acquired by a laboratory vehicle under high dynamic loads and characterized by high lateral accelerations.

TL;DR: In this paper, a method for assisting a driver of a motor vehicle (1) in parking into a parking space (12 to 19), with the aid of a driver assistance system (3), is provided.
Abstract: A method is provided for assisting a driver of a motor vehicle (1) in parking into a parking space (12 to 19), with the aid of a driver assistance system (3), according to which a plurality of parking spaces (12 to 19) are detected by means of a sensor device (6 to 11) of the driver assistance system (3), and for at least two detected parking spaces (12 to 19) information is output by means of an output device (5) of the driver assistance system (3). For each of the at least two parking spaces (12 to 19) a parking trajectory (28) of the motor vehicle (1) from a current position of the motor vehicle (1) into the respective parking space (12 to 19) is determined by the driver assistance system, and the information is generated on the basis of the respective parking trajectories (28).
