Definitions

  • the invention relates to an apparatus and a method for setting an operating stage of an automatic transmission of an IC motor vehicle with the features of the preamble of independent claim 1.
  • Modern devices for setting an operating stage of an automatic transmission have actuating means which transmit information about the operating stage selected by the driver, for example the parking position operating stage P, electrically to a transmission control unit.
  • the transmission control unit adjusts the desired operating level via actuators arranged on the transmission as a function of the presetting of the actuating means and optionally further parameters.
  • This method for setting the operating stage is also referred to as "shift-by-wire.”
  • such devices have a speed detection means which detects the instantaneous vehicle speed and transmits this value to the transmission control unit
  • the parking position operating stage can only be set if the detected vehicle speed is less than a predefined limit value of 2 km / h, for example.
  • the known methods have the disadvantage that the driver often regards the audible or visual warning signal as disturbing and at a later time when the vehicle is stationary, possibly in spite of the warning signal, forgets to set the parking position operating stage again on the actuating means.
  • the device according to the invention with the characterizing features of claim 1 has the advantages that the acoustic or visual warning signal, which is usually perceived as disturbing, is eliminated and the security risk of an unintentional failure to enter the parked operating mode if the driver forgets should be minimized again to request the park position operation stage at a later time.
  • the vehicle brake is operated in accordance with a first brake control program such that the vehicle speed becomes less than the limit value and the parked operating level is set on the gearbox.
  • a Au-uhrungsfeeispieL in which a second limit value of the vehicle speed, which is greater than the first limit, is predetermined.
  • the first brake control program may advantageously provide for a moderate actuation of the vehicle brake, so that the deceleration is hardly perceived as jerk by the driver of the vehicle.
  • the vehicle brake can be provided to actuate the vehicle brake according to a second brake control program at a detected vehicle speed below the first limit value.
  • the second brake control program can provide a strong actuation of the vehicle brake in full braking mode until the vehicle is completely stationary.
  • the single figure shows schematically the structure of a drive train a Kraft ⁇ vehicle with a vehicle brake and with a device according to the invention for setting an operating stage of the automatic transmission. Description of the exemplary embodiments
  • FIG. 1 schematically shows the drive train of a vehicle 1 with a combustion engine 2 ".
  • the output shaft of the internal combustion engine is coupled to the input side of a transmission 4 via a converter 3 or a clutch.
  • the Aus ⁇ gangsseite of the transmission 4 acts via a differential 5 on a drive axle 6, which drives the wheels 8.
  • Vehicle brakes 7 allow a deceleration of the vehicle.
  • a speed detection means 13 detects the speed of the vehicle.
  • a speed sensor can be used, which ver ⁇ works the output speed of the transmission output side as a speed signal ver ⁇ . But it is also possible to detect the rotational speed of the wheels 8 or another size representing the vehicle speed.
  • the transmission is an automatic transmission, which may be, for example, a fully automatic transmission or an automated manual transmission.
  • An actuating means 9 makes it possible for the driver to specify the operating stage P 5 R, N, D and possibly further operating stages of the transmission 4, the operating stage P being associated with a parking position of the transmission in which the transmission has a position blocking the locomotion occupies and optionally also a handbrake is operated to prevent accidental rolling away of the vehicle.
  • the actuating means 9 is electrically connected to control means 10.
  • the control means may comprise, for example, a first control unit 11 for transmission control and a second control unit 12 for brake control. However, it is also possible to provide a common control unit.
  • the first control unit 11 processes the signal received by the actuating means 9 and actuates actuators 14 of the transmission 4 as a function of this and optionally as a function of further parameters in order thus to set the operating stage of the transmission. For this purpose, the detected speed of the vehicle Vist from the detection means 13 is transmitted to the first control unit 11.
  • the control unit 11 checks whether the vehicle speed Vact is less than a predefined first limit value V1 of the vehicle speed of, for example, 2 km / h. If this is the case, then the actuators 14 of the transmission are activated in such a way that the parking-site operating fluids are set on the transmission 4.
  • the first control unit 11 transmits a signal to the second control unit 12, whereupon the second control unit actuates the vehicle brakes 7 in accordance with a first brake control program.
  • a first brake control program This can be done, for example, as full braking.
  • the brake is actuated such that the driver preferably does not feel any jerk and the vehicle is braked moderately until the vehicle speed drops below the limit value V1.
  • the first control unit automatically adjusts the parking position operating stage on the transmission 4, without the driver having to request the parking position P again with the actuating means 9. If the vehicle speed drops below the limit value V1, a further braking intervention can also take place in accordance with a second brake control program on the vehicle brake 7, which second brake control program intends in particular full braking of the vehicle until complete standstill.
  • the control means 10 can furthermore be preset with a second limit value V2 of the vehicle speed, which is greater than the first limit value V1. If the parking position P is requested by the actuation means and the vehicle speed Vist is greater than the second limit value V2, then the requirement of the parking position is interpreted as an incorrect operation and ignored. If the vehicle speed is less than the second limit value V2, then the method described above is followed by braking the vehicle to a speed below the first limit value V 1 via a braking intervention on the vehicle brake 7. Then, the park position operating stage is set on the transmission 4.

Abstract

Des dispositifs connus pour régler un palier de fonctionnement d'une boîte de vitesses automatique dans un véhicule à moteur comprennent un moyen (13) pour saisir la vitesse du véhicule, un actionneur (9) pour déterminer un palier de fonctionnement de la boîte de vitesses automatique (4) et des éléments de commande (10) pour régler un palier de fonctionnement de la boîte de vitesses (4) en fonction de la détermination des actionneurs (9), les éléments de commande n'enclenchant le palier de stationnement (P) que lorsque la vitesse du véhicule (Vist) saisie est inférieure à une première valeur limite prédéfinie (V1). L'invention est caractérisée en ce que, lorsque le palier de stationnement (P) est déterminé par les actionneurs (9) et la vitesse du véhicule (Vist) dépasse la première valeur limite (V1), les éléments de commande (10) actionnent le frein (7) du véhicule conformément à un premier programme de commande de freinage, de manière que la vitesse du véhicule (Vist) soit inférieure à la première valeur limite (V1) et le palier de stationnement (P) soit enclenché par les éléments de commande de la boîte de vitesses (4).
