Abstract: A method is for reducing an energy demand and/or energy consumption by a vehicle, in particular a motor vehicle. The vehicle includes a steering system having at least two wheel steering angle actuators for changing a respective wheel steering angle of a vehicle wheel on an individual wheel basis, and a vehicle sensor system for driving situation recognition. In at least one operating state, in which a predefined driving situation is identified using the vehicle sensor system, a power consumption by at least one wheel steering angle actuator is reduced in order to reduce the energy demand and/or energy consumption, in particular such that the power consumption by the at least one wheel steering angle actuator is below a power consumption by the at least one wheel steering angle actuator planned for in the identified predefined driving situation.

Abstract: A method for influencing a stiffness behavior of a vehicle assembly of a vehicle includes changing a wheel steering angle of at least one vehicle wheel of the vehicle using at least one wheel steering angle controller of a steering system of the vehicle, and reducing a stiffness of the vehicle assembly by configuring and/or adapting a chassis characteristic of the vehicle. The method further includes actuating the at least one wheel steering angle controller in at least one driving mode state to selectively influence the stiffness behavior of the vehicle assembly, such that a change in the stiffness of the vehicle assembly caused by the configuration and/or adaptation of the chassis characteristic is compensated as a function of a driving situation.
