    Abstract: A tire (100) rolls on a surface (105). A method (600) for providing maximum traction coefficient between the tire (100) and the surface (105) include steps for detecting a momentary slip of the tire (100) on the surface (105); detecting a momentary traction coefficient; forming a tuple (410, 510) from the slip and the current traction coefficient; choosing a characteristic curve (205, 305) from a number of predetermined characteristic curves (205, 305) on the basis of the tuple (410, 510), whereby each characteristic curve (205, 305) describes a traction behavior of the tire (100) or a corresponding characteristic pitch; determining the maximum traction coefficient on the basis of the selected characteristic curves (205, 305); and thus providing the maximum traction coefficient.

    Abstract: A trajectory planning system for a vehicle includes a sensor system for measuring an actual curvature on the basis of a respective current yaw rate, a memory containing a target trajectory with target curvatures, wherein the trajectory planning system determines target yaw rates from the target curvature, and a steering system that uses steering variables to obtain target curvatures in actual curvatures. The system determines a respective first actual derivative of the measured respective current actual yaw rate over time and a respective first target derivative of the respective current target yaw rate over time. A correlator determines a respective current delay on the basis of the respective first actual derivatives and the respective first target derivatives in a current yaw rate segment, and a parameter estimator recursively estimates the delay between the target yaw rate and the actual yaw rate on the basis of respective current delay inputs.

    Abstract: A vehicle control element measures concentrations of substances in air of vehicle, where the air includes the exhalations and/or body odors or other odors from occupants within the vehicle. A measurement chamber on or in the vehicle control element may include at least one first entry hole through which air can be drawn into the measurement chamber; at least one first exit hole through which air can be discharged from the measurement chamber; a polygonal, elliptical, or circular cross section; reflective inside walls; a laser located at a second entry hole in the measurement chamber, with which laser beams are projected into the measurement chamber through the second entry hole; and a detector located at a second exit hole in the measurement chamber with which laser beams exiting the measurement chamber through the second exit hole are detected. The vehicle control element also includes an interface to an evaluation device.
