It is proposed that in the transmission (1) a module carrier (2) is arranged, on which at least one sensor (4) for detecting vehicle, engine and / or transmission-specific actual values is arranged.

Description

  • The The invention relates to a device for electronic control an automatic transmission according to the preamble of claim 1.
  • Electronic transmission controls are also known by the abbreviation EGS, for example by the DE 199 54 921 A1 the applicant. The EGS is an electronic control unit whose task is, inter alia, in the control of a hydraulic switching device, which causes the circuit of the individual gears of the motor vehicle. The EGS receives vehicle-specific, engine-specific and gearbox-specific input signals, which are recorded via sensors. Engine-side input signals are, for example, the engine speed or the throttle position, transmission-side input signals include, for example, the output speed of the transmission, which is detected in the transmission via a speed sensor. Vehicle-side input signals are z. Example, the position of the automatic selector lever, which is detected by a position sensor and fed as an input to the EGS. Such a position detection device was by the DE 199 09 496 A1 the applicant known. Since the EGS and the sensors are positioned at different locations in the transmission or in the vehicle, there are electrical connections to the EGS, for example as a serial data bus (CAN data bus). The various signal lines are brought together in a plug which forms a plug contact with the EGS ( EP 0 758 726 A2 ).
  • By the DE 101 34 053 A1 the applicant has become known an electrical central connector for an electronic control unit (EGS), in which the various signal lines are combined and fed via a plug connection of the EGS.
  • It it is known that the EGS also connected to a storage unit is in which manufacturing properties of devices and components of the transmission and operating and functional data stored are.
  • By the DE 101 10 729 A1 a so-called identification module has been known, which has a property storage unit and an operating data storage unit, preferably as an integrated unit. The identification module is arranged in the transmission and connected via a communication and data line with an electronic control unit (EGS). The data stored in the identification module can be read out at the start of the engine or as needed and read into the EGS. The EGS is thus independent of the respective transmission or vehicle.
  • By the DE 43 02 248 C2 an electronic control of a motor vehicle automatic transmission has been known, wherein in the transmission, a property storage unit and sensors are arranged, which communicate via electrical lines with an outside of the transmission arranged electronic control unit (EGS).
  • adversely in the aforementioned prior art, that the individual with the EGS communicating components such as speed sensors, position sensors and storage units are each arranged separately in or on the transmission and individually or over a common line, z. B. a harness connected to the EGS are. This results in additional costs due to more effort in production and assembly and the number of components associated with a higher number from contact points and a higher one Number of assembly steps. This carries additional sources of error in itself and can negatively affect the quality of the product.
  • It is the object of the present invention, the circuitry Effort for to reduce the input signals of an electronic control unit and therefore to reduce costs.
  • The The object of the invention is characterized by the features of claim 1 solved. Advantageous embodiments of the invention will become apparent from the Dependent claims.
  • According to the invention is in Gearbox a module carrier provided on which at least one sensor for detecting vehicle, engine or transmission-specific actual values arranged is. Preferably, the module carrier is on a hydraulic control unit arranged, which is located within the transmission housing. An advantage of the module carrier according to the invention is that at least one Sensor and preferably also the storage unit arranged thereon are and can be integrated into a module. The sensors are These are mainly speed sensors for detecting the engine and / or the transmission output speed to pressure sensors or position sensors, which the position of the selector lever recognize the transmission. The signal lines of the sensors are in the module carrier or the module housing integrated and lead to a common module output in the form of a plug. The storage unit, in which manufacturing as well as functional and operational data are stored, can be mounted on the module rack or arranged separately be. The memory unit is also connected to the common output connected to the module in the form of a plug. At initial initialization of the transmission, the data from the memory unit into the EGS read.
  • The electronic control unit (EGS) can either be inside the gearbox or Outside on the gearbox or be positioned in the vehicle at a location remote from the transmission, being a data and Communication connection to the module carrier, preferably via a serial Data bus (CAN bus or LIN bus) is provided. Advantageous in the inventive arrangement the sensors and the storage unit in various combinations is that extra cable connections, Contact points and assembly steps are eliminated and thus costs be saved. About that out comes the quality of the product due to a lower error rate in the production increased.
  • To an advantageous embodiment is the module output, on which the Signal lines merged are designed as a central plug, which also with the module can be integrated. Possible is also a flexible electrical connection between central plug and module housing. The central plug is contacted with the EGS.
