Definitions

  • the invention relates to a device for controlling at least one electromechanical operating device of a motor vehicle, in which an accelerator pedal, a brake pedal and / or a steering wheel can be adjusted.
  • drivers of a motor vehicle operate the brake pedal, for example, by applying a corresponding force which generates a pedal travel.
  • the brake pedal is connected to a master brake cylinder via a linkage, which hydraulically transmits the driver's specification to the wheel brakes.
  • the relationship between force and displacement is determined by a swallowing volume of the brake system, throttling points, for example in an anti-lock braking system, and by a gain factor of the brake booster.

  • the steering motor can also implement steering assistance that depends on the driving speed of the vehicle.

  • the brake pedal 3 shows the accelerator pedal 2 and the brake pedal 3 in the non-actuated state in solid lines. If the accelerator pedal 2 is now actuated (dashed line), the brake pedal 3 also moves (dashed line) without the driver touching the brake pedal 3. This can ensure that the distance from the accelerator pedal to the brake pedal required by the driver is minimized and in particular that the driver's foot does not move back onto the brake pedal. dal 3 is more necessary. The transfer times can hereby be greatly reduced, since the accelerator pedal 2 and the brake pedal 3 are now positioned approximately on one level with the driver. The brake pedal 3 generates no braking request in the dragged position. Only when the driver steps on the brake pedal 3 is a braking request generated electrically.
  • That the driver actuates the brake pedal 3 or steps on the brake pedal 3 can be seen from a force signal or from a load flow of the towing pedal motor 17.

  • the steering motor 8 in the actuation module 1 can also generate a torque that gives the driver an indication of the lateral forces that can be transmitted on the road. So that the electric or hydraulic drive unit of the steering gear or possibly the single-wheel steering, for example in a vehicle standing on the curb, does not generate excessively large forces, the steering motor 8 generates a torque that counteracts the driver in order to give him feedback on the forces occurring on the wheel. When the steering wheel 10 is actuated quickly, which is usually generated by an overreaction of the driver, the steering motor 8 can generate a damping torque.
  • a vehicle speed-dependent steering support or steering ratio is also can be implemented electronically.
  • the steering motor 8 with its position signal serves as a steering angle sensor for the drive unit of the steering gear or possibly the independent wheel steering.
  • FIG. 4 shows a graphical representation of the brake pedal characteristic.
  • the right side of the abscissa shows a brake pedal force Fp in Newtons.
  • the left side of the abscissa shows a brake pedal actuation Sp in millimeters.
  • the ordinate shows a vehicle deceleration Z.
  • the vehicle deceleration is assumed here with idealized or predetermined boundary conditions. It should be noted that the relationships shown are only schematic and exemplary.
  • a quasi-static relationship between the brake pedal force Fp and the deceleration Z can be achieved by appropriately setting the brake pedal characteristic via, for example, the pedal motor 17.
  • the brake system can be are set function (BA), so that a lower brake pedal force Fp causes a greater deceleration Z.
  • the deceleration Z is plotted against the pedal actuation path Sp.
  • the pedal movement is only dependent on the volume of the brake calipers.
  • the relationship between Sp and Z is quasi static, so that a more direct relationship between the pedal travel Sp and the actual vehicle deceleration Z is achieved.
  • a brake assistance function (BA) is also switched, so that a shorter pedal actuation path Sp results in a higher vehicle deceleration Z.

Abstract

L'invention concerne un dispositif pour la commande d'au moins un dispositif de manoeuvre électromécanique d'un véhicule automobile, qui est commandé par un accélérateur (2), une pédale de frein (2) ou un volant (10). Le dispositif selon l'invention contient en particulier un module d'actionnement (1) pouvant être déplacé dans le sens horizontal ou vertical afin de régler l'accélérateur (2), la pédale de frein (3) ou le volant (10) selon les besoins du conducteur. Un moteur de pédale de frein (17) peut entraîner la pédale de frein (3) en fonction d'une position de l'accélérateur (2) détectée par un capteur d'accélérateur de sorte que l'accélérateur (2) et la pédale de frein (3) sont, si possible, toujours positionnés sur un plan par rapport au conducteur. Selon l'invention, le moteur de pédale (17) peut aussi influer sur une caractéristique de la pédale de frein de telle façon que cette dernière soit pratiquement statique. On évite ainsi un amortissement de la pédale de frein (3) dépendant de la course. Le moteur de pédale (17) et un moteur de direction (8) peuvent en outre renvoyer des informations haptiques sur l'état du véhicule.
