  • Publication number: 20240067263
    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.

  • Publication number: 20230356773
    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.

  • Patent number: 11318991
    Abstract: A method is for controlling a wheel steering angle of at least one vehicle wheel of a vehicle, in particular of a motor vehicle. The vehicle has a steer-by-wire steering system including at least one wheel steering angle control element, which is provided at least for modifying the wheel steering angle of the vehicle wheel according to a steering demand. In at least one operating mode, in which the vehicle is at a standstill and a steering demand is received, the wheel steering angle of the vehicle wheel is at least substantially maintained at a constant value and a desired wheel steering angle for the vehicle wheel is determined in accordance with the steering demand. In at least one subsequent additional operating mode, in which the vehicle is moving, the wheel steering angle is adjusted to the desired wheel steering angle by the wheel steering angle control element.

  • Patent number: 7778814
    Abstract: A method and a device for simulating an automation system are disclosed. The aim of the invention is to allow an automation system to be simulated in such a way that simulation components operating at very different computing speeds can be combined into an overall simulation. Said aim is achieved by a method comprising a control component that can be clocked using an external timing source and at least one simulation component which can be clocked using an external timing source. A coordinated clock system is provided for the control component and the at least one simulation component by means of a control component-independent timing coordinator.

  • Patent number: 7337017
    Abstract: The invention relates to an automation system with a programmable controller (6), the programmable controller (6) exhibiting deterministic behavior and being provided to produce at least one first result value (13) from at least one first input value (3, 4, 5), as well as a method for controlling a technical process or a technical system with an automation system of this type. To improve the reaction of the automation system in situations for which no account is taken at the engineering stage, it is proposed that additional means for affective control (7) are provided which produce at least one state value (9) by means of situation evaluation means (8) from at least one second input value (1, 2) and for linking the state value (9) with an attribute profile (10) in order to form a second result value (11), the linkage means (14) being provided to link the first result value (13) to the second result value (11) in order to form at least one output value (15).
