  • Publication number: 20250016025
    Abstract: A secondary control unit for a vehicle with a primary control unit and a data transmission path, in which the primary control unit is configured to provide first payloads via the data transmission path under a first sender identifier uniquely referring to the primary control unit. The secondary control unit is configured to provide second payloads under a second sender identifier uniquely referring to the secondary control unit via the data transmission path. Furthermore, the secondary control unit is configured to verify a condition and, if the condition is present, to provide substitute payloads under the first sender identifier via the data transmission path, wherein the substitute payloads are the first payloads or payloads related thereto.

  • Patent number: 10377357
    Abstract: A method and computer program for electronically regulating the brake force distribution in a pressure medium-operated brake system of a vehicle having at least one front axle brake circuit, associated with a front axle, and at least one rear axle brake circuit, associated with at least one rear axle, in which when the brake system is operated, a rear axle brake pressure, acting in the at least one rear axle brake circuit, is regulated to prevent locking of the rear wheels before locking of the front wheels, and in which the brake pressure at the rear axle is limited only while a pressure value which acts in the rear axle brake circuit is below a prespecified pressure threshold value, but the brake pressure at the rear axle is not limited if the pressure value acting in the rear axle brake circuit is not less than the prespecified pressure threshold value.

  • Patent number: 9944261
    Abstract: A method is provided for controlling a pressure control device of a pressure-medium brake system of a vehicle which individually controls brake pressures in brake cylinders of wheels of an axle. The pressure control device includes a relay valve. In order to compensate for response sluggishness of the relay valve, shut-off valves connected between the relay valve and their respective brake cylinders are not switched into a passage position in which pressure is forwarded to the brake cylinders until a permissible pressure gradient exists between the working pressures of the relay valve and the brake pressures in the brake cylinders.

  • Patent number: 9193338
    Abstract: A pressure-medium-activated brake device of a vehicle without brake pressure control but with brake slip control (ABS) for driver-independent control of the brake slip during a braking process, and traction control (TCS) for driver-independent control of the drive slip during an acceleration process.

  • Patent number: 8433480
    Abstract: A device and a method for triggering personal protection devices, characterized in that a roll rate sensor generates a roll rate while an acceleration sensor detects the transverse acceleration and the vertical acceleration. An integrator is provided to integrate the roll rate to yield an angle. The integrator starts integrating the roll rate when the roll rate exceeds a first threshold value and it stops the integration when the roll rate falls below a second threshold value. In addition, a threshold value controller is provided, adjusting the first and/or second threshold value according to the transverse and/or vertical acceleration. A processor triggers personal protection devices according to the angle and other criteria.

  • Publication number: 20130030963
    Abstract: A business object model, which reflects data that is used during a given business transaction, is utilized to generate interfaces. This business object model facilitates commercial transactions by providing consistent interfaces that are suitable for use across industries, across businesses, and across different departments within a business during a business transaction. In some operations, software creates, updates, or otherwise processes information related to a financial plan, a financials notification, a bank directory entry file and/or a direct debit mandate business object.

  • Patent number: 8185271
    Abstract: A method and device for determining a roll angle for occupant protection devices. Transverse acceleration and vertical acceleration of a vehicle are detected, and the roll angle of the vehicle is estimated on the basis of the detected lateral acceleration and the detected vertical acceleration, additional driving dynamics quantities, including a vehicle speed, a yaw angle and a float angle being determined, and centripetal acceleration being calculated from these driving dynamics quantities, formula, to improve the estimate of the roll angle.

  • Patent number: 7810067
    Abstract: Systems and techniques to manage and represent development processes. In general, in one implementation, the technique includes a method for managing a software development process. The method includes providing a cookbook describing tasks in a framework of the development process and managing performance of the development process with the cookbook. A first task description identifies an activity in the development process, an input for performance of the activity, an output consequential of performance of the activity, and instructions for performance of the activity.
