Definitions

  • the present invention relates to a method for realizing steering assistance of a steering system of a vehicle.
  • Rotor position sensor of the drive motor is defective and therefore the drive motor can not be controlled.
  • One object is therefore to provide a method which, in the event of a defect in the control of the drive motor, has the greatest possible value
  • Driving comfort by providing a steering assistance allows.
  • a method for realizing a steering assistance of a steering system of a vehicle is provided, wherein the steering assistance a drive motor and a
  • Driving the drive motor having a feedback loop comprising the steps of: detecting a disturbance of the feedback loop, switching off the feedback loop and driving the drive motor to generate the steering assistance without feedback loop.
  • a vehicle may be a passenger car
  • a control (without feedback loop) instead of a control (with feedback loop) of the drive motor can take place instead.
  • this can not be optimally adapted to the current driving situation steering assistance provided.
  • a certain amount of steering assistance can be generated, thereby reducing the otherwise necessary manual torque at the steering wheel of the respective vehicle.
  • a steering system is provided with a control unit for a vehicle, wherein the control unit comprises a memory means with a computer program stored thereon, wherein the computer program for carrying out a method according to one of claims 1 or 2 is configured.
  • the computer program for carrying out a method according to one of claims 1 or 2 is configured.
  • a computer program for carrying out a method according to one of claims 1 or 2 is provided.
  • a fifth embodiment of the invention is a
  • Program code means stored on a computer-readable medium to perform the method of any one of claims 1 or 2 when the program code means are executed on a computer.
  • the drive motor is controlled in order nevertheless to generate steering assistance and thereby reduce the manual torque.
  • a control circuit for controlling the drive motor of the steering assistance to control the drive motor so to operate without control circuit.
  • the ride comfort is increased in case of failure.
  • the individual features can also be combined with each other, which can also be partially beneficial effects that go beyond the sum of the individual effects.
  • FIG. 1 shows a flow chart for illustrating the method according to the invention in the event of a failure of the feedback loop
  • Fig. 2 is a flowchart illustrating a particular embodiment of the method according to the invention in case of failure of the rotor position sensor.
  • Rotor position sensor of the drive motor is defective.
  • Other examples of defects or defects that lead to a malfunctioning control are program flow errors or current measurement errors. If such errors exist, then the control of the drive motor can be switched off and the drive motor is controlled 2. This results in a not optimal steering assistance, but at least a reduced steering assistance can be provided. It can be reduced by the necessary hand moment compared to a steering system without steering assistance, whereby the ride comfort can be increased in case of failure. Therefore, according to the invention, the feedback loop is shut down, and the drive motor is operated without regulation (control plus feedback loop).
  • FIG. 2 shows a flow chart of a sequence with a query 3 as to whether the rotor position sensor is defective. If the rotor position sensor is defective, correct control of the drive motor can not take place.
  • Steering assistance can be increased.

Abstract

L'invention concerne un procédé permettant de réaliser une assistance du système de direction d'un véhicule, l'assistance de direction comportant un moteur d'entraînement et une commande pourvue d'une boucle de rétroaction. Ledit procédé comprend les étapes qui suivent consistant à : constater une défaillance de la boucle de rétroaction (1); mettre la boucle de rétroaction (1) à l'arrêt; et activer le moteur d'entraînement (2) pour produire l'assistance de direction sans boucle de rétroaction.
