Publication number: 20250040466Abstract: A method for controlling traction of a wheeled vehicle or a vehicle combination having a tractor vehicle and at least one trailer vehicle. A sensor device on a coupling element of a trailer device transmits coupling forces in x, y, and z directions to the coupling element of the tractor vehicle, which are measured and emitted as force signals. From these force signals, an evaluation unit determines the coupling force acting in the respective vehicle direction and transmits them to a control unit. Traction of the tractor vehicle is adapted to suit the properties of the ground surface. Using sequences of the coupling forces, the dynamic fraction if filtered out and from these a characteristic value is determined and transmitted to the control unit. If the characteristic value exceeds a limit value, then at least one measure to improve the traction of the tractor vehicle is carried out.Type: ApplicationFiled: November 23, 2022Publication date: February 6, 2025Applicant: ZF CV Systems Global GmbHInventors: Mirko Brütt, Daniel Pfefferkorn, Jan Spremberg, Thomas Wolf
