Method for determining a toothed rack force for a steering device in a vehicle |
摘要 |
Disclosed is a method for determining a toothed rack force on a steering device in a vehicle, wherein the toothed rack force (forZS) is determined as a function of a plurality of models, and wherein a component (forESM) of the toothed rack force (forZS) which relates to a driving process is generated by means of a first model, and a component of the toothed rack force (forZS) which relates to a parking process is generated by means of a second model. |

1. A method for determining a toothed rack force representing force conditions at a front axle of a vehicle having a power steering system that includes a steering device and a control unit, the method comprising:
receiving at the control unit operating variables of the vehicle; and determining by the control unit the toothed rack force (forZS) as a function of a plurality of models, wherein a component (forESM) of the toothed rack force (forZS) which relates to a driving process is generated by means of a first model, and a component of the toothed rack force (forZS) which relates to a parking process is generated by means of a second model; and using the determined toothed rack force by the control unit in connection with a power steering system operation of the vehicle; and wherein an adaptation is carried out as a function of at least one lateral force (fyADA), at least for the component (forESM) relating to a driving process; and wherein the lateral force (fyADA) is found as a function of a modeled lateral force (fyMDL) that is found by means of a single-track model, an actual lateral force (fyFZG), and a slip angle (angSID). |
