Definitions

  • the present invention relates to a device for braking with the features of the preamble of patent claim 1.
  • the device includes a brake control system to which a detection device with a first sensor device comprising a first sensor assigned to the gas pedal of the vehicle is assigned.
  • a detection device with a first sensor device comprising a first sensor assigned to the gas pedal of the vehicle is assigned.
  • the first sensor supplies a first signal to the detection device.
  • a braking process is triggered automatically by the detection device.
  • the known brake control system assumes that the accelerator pedal was depressed at all before the sequence of signals or steps. If the driver only has his foot loosely on the accelerator pedal so that the accelerator pedal is not or practically not depressed, the first signal which signals the start of a display reflex foot movement and activate the detection device, do not occur at all. The detection device may then determine the second signal, but this alone must not trigger the panic-like or automatic braking process.
  • the invention has for its object to provide a means with which it is also possible to trigger the first signal, which should indicate the start of the reflex-like foot movement and activate the detection device, even when the foot is in front of the panic-like one
  • the reflex movement was only loosely on the gas pedal.
  • the solution according to the invention is that the position of the driver's foot on the accelerator pedal that is not depressed is associated with a reflex sensor that detects a jerky movement of the foot and that supplies an auxiliary signal to the detection device that replaces the first signal.
  • jerky path movement includes a panic-like reflex movement (and vice versa).
  • the invention ensures that a first signal, which activates the detection device and thus makes automatic or panic braking possible at all, is made available in the form of the auxiliary signal emitted by the reflex sensor even if the driver is currently in front of the vehicle required brakes had not pressed the accelerator at all.
  • the only requirement for the emergence is that the driver's foot is at least in the vicinity of the accelerator pedal, namely so close to the pedal that the reflex sensor can record the jerky movement of the foot.
  • the reflex sensor should also be able to detect at least a small path of a reflex movement of the foot, because the speed at which the foot is pulled away is of interest, and not only the presence of the foot at the measuring point.
  • a spring-loaded button is provided as a reflex sensor on the tread of the accelerator pedal, the restoring force of the button spring to be pressed when the button is pressed against the restoring force of the main spring to be pressed when the accelerator pedal is pressed. The result of this is that the push button must be pressed in continuously with a minimal, barely noticeable force which does not tire.
  • the first signal required to activate the detection device is also available in the form of the auxiliary signal if no gas was given at all before the braking suddenly required.
  • a button provided on the tread of the accelerator pedal can preferably be designed as a small pedal that can be pivoted about an axis (inside the main pedal body or on its tread).
  • a mechanical spring can be assigned to this small pedal or auxiliary pedal, which is pressed in when the (small) pedal is lightly touched by the foot in the direction of the step surface of the main pedal.
  • the mechanical spring of the auxiliary pedal is optionally equipped with a displacement sensor, the reflex sensor according to the invention.
  • the reflex sensor should register the speed at which the foot may be lifted off the accelerator pedal or the auxiliary pedal. If the take-off speed meets the requirements for the creation of the first signal, the detection device is activated for the reception of a second signal. Thus, when the second signal is received, the braking process - as in the known one - is triggered immediately - that is, even before the foot hits the brake pedal.
  • the reflex sensor can also be designed as a light barrier device or similar contactless means. It is only important according to the invention to determine whether a reflex or jerky movement of the foot begins from the area of the accelerator pedal in the direction of the brake pedal, and the detection device, if applicable, if necessary to activate accordingly.
  • FIG. 1 shows an accelerator pedal with an auxiliary pedal
  • FIG. 2 shows an accelerator pedal with a contactless reflex sensor
  • FIG. 1 shows an accelerator pedal, designated overall by 1, whose pivot axis 2 is associated with a pedal return spring 3 with the spring constant R1.
  • a reflex sensor for supplying a first signal which activates a detection device, is coupled to the axis 2 or the spring 3 in accordance with the aforementioned WO 95/01898. Obviously, this first signal can only be generated if the pedal 1 was pressed in.
  • the accelerator pedal 1 is connected at the upper end to a fastening point 4 with a throttle cable 5. At the lower end, the accelerator pedal 1 has a pedal body 6 with the tread 7 facing the driver's foot.
  • an auxiliary pedal 8 is integrated into the tread surface 7, which can be pressed against the tread surface 7 by pressing in a key spring 9 with the spring constant R2.
  • R2 should be small against Rl.
  • the auxiliary pedal 8 can be operated in any way, e.g. can be movably attached to the pedal body 6 by articulation on an axis 10 assigned to the step surface 7. It can also be designed as a push button body coupled only with the spring 9.
  • the auxiliary pedal 8 or the button can also be pressed in without accelerating, that is, without the accelerator pedal 1 being actuated.
  • the auxiliary pedal 8 or the key spring 9 is assigned a reflex sensor 11.
  • the latter should be able to determine whether the auxiliary pedal 8, if applicable, the driver's foot pressing in against the spring force R2 is moved or lifted away from a position on the pedal body 6 at a normal speed or in a jerky or reflex manner.
  • a contactless reflex sensor in order to capture the described auxiliary or Reflex signal not a mechanical button, but a contactless reflex sensor is provided.
  • contactless transmitters or receivers 12 are positioned next to the pedal body 6, for example at the level of the driver's foot located on or in the vicinity of the pedal body 6, which can determine whether the driver's foot is moving at normal speed or jerkily or reflexively Pedal body 6 is moved away.
  • the transmitters and receivers 12 are to give an auxiliary signal (replacing the first signal) to the detection device in the event of a reflex movement and thus activate the detection device for the reception of a second signal.
  • a device for braking a vehicle with a panic brake control system is described, the brake control system being assigned a detection device for determining the position of the driver's foot, such that when the driver's foot moves reflexively and rapidly from a first position to a second Position the detection device automatically brakes the vehicle via a brake control system.
  • a reflex-like start of the movement of the driver's foot from an unpressed position on the accelerator pedal is detected with the aid of a reflex sensor.

Abstract

L'invention concerne un dispositif de freinage d'un véhicule équipé d'un système de commande de freinage d'urgence. Un dispositif de détection servant à détecter la position du pied du conducteur est affecté audit système de commande de freinage, de sorte que, en cas de mouvement rapide, de type réflexe, du pied du conducteur entre une première et une deuxième position, le dispositif de détection freine automatiquement le véhicule par l'intermédiaire du système de commande de freinage. Selon l'invention, un détecteur de réflexe détecte un début de mouvement, de type réflexe, du pied du conducteur, à partir d'une position dans laquelle le pied n'appuie pas sur la pédale d'accélérateur.
