Definitions

  • the invention relates to an electronic transmission control with the features specified in the preamble of claim 1.
  • Conventional automatic car transmissions have a gear selector lever that can be operated by the driver and is located in the vehicle interior.
  • This selector lever is mechanically connected to a selector slide in the transmission, which sets the drive level P ("park"), R ("reverse"), N ("idle speed”) or D ("forward drive”) set on the selector lever in the transmission.
  • the direct mechanical coupling of the selector lever to the selector slide via a rod, a Bowden cable or the like ensures that the hydraulic state of the transmission with the corresponding speed level P, R, N or D always corresponds to the range set by the driver.
  • the mechanical tolerances of the system can be included in the reliability considerations and a high degree of reliability of the correspondence can be ensured by appropriate adjustment of the system.
  • the mechanical system of the hydraulically operated transmission can still work independently of the transmission control by automatically switching the transmission to a default position in the event of a defect, in which at least limited driving is possible.
  • the default state can be represented, for example, by a constant shift position in the second forward gear. In this gear there is both starting and driving at a speed of the order of magnitude of about 50 km / h, which allows the vehicle to be transferred to a workshop under its own power.
  • the invention is based on security and availability criteria. On the one hand, it must be ensured that the driver request transmitted via the signal line is correctly implemented in the actuator by the transmission control. The latter must therefore move the selector slide hydraulically or electrically into the target position specified by the driver. In addition, the availability of the transmission and in particular the drive level control must be as high as possible, since failure of the control can lead to the vehicle stopping.
  • the invention proposes, according to the characterizing part of claim 1, that the transmission control device has two control processors each connected to the signal line. These two control processors are implemented by a speed control processor for controlling the actuator and a function processor for further transmission functions, such as valve control, speed evaluation and gear selection. These two control processors are now coupled to each other and monitor each other for proper function that in the event of a malfunction of one of the control processors, the other control processor deactivates it.
  • the speed control processor can determine that the function processor has left the proper function mode. As a result, the functional processor is deactivated. Conversely, if the function processor determines that the speed control processor is no longer operating properly, the speed control processor can be put out of operation directly. Furthermore, the function monitoring on the part of the function processor provides direct access to the actual control device of the actuator, so that the safety-relevant drive level control can be deactivated immediately.
  • This 1 shows a block diagram of an electronic transmission control.
  • the electronic transmission control has a gear selector lever 1 which can be actuated by the driver and which is arranged in the interior of the vehicle.
  • This selector lever 1 is adjustable in the usual automatic transmission speed levels P, N, R and D.
  • the selector lever 1 is coupled via a bus line 2 to two control processors, such as a drive level control processor 3 and a function processor 4.
  • the driving stage control processor 3 is connected with its control output 5 to a control device 6, which is, for example, a driver circuit for the hydraulic system of an actuator 7. This is flanged to the automatic transmission and sets the selector slide of the transmission to the drive level P, N, D or R set by the driver.
  • This actuator 7, which - as mentioned - can work hydraulically or electrically, is connected to a selection range sensor 8 which detects the current position of the selector slide. Its signal output 9 is fed back via a feedback line 10 and an A / D converter 11 to the speed control processor 3, so that the latter can monitor the actual position of the selector slide on the transmission.
  • the two control processors 3, 4 are coupled to one another by a coupling line 12 between their serial interfaces 13, 14 in such a way that they can monitor one another for correct functioning. This is helped by the fact that the clock generated by a quartz module 15 of the speed control processor 3 is made available to the function processor 4 via its so-called "clock-out output" 16 and a connection line 17. is set so that the speed control processor 3 a
  • ⁇ provides system clock for the function processor 4.
  • the speed control processor 3 has its own clock signal independently of the function processor 4.
  • the voltage supply of the two control processors 3, 4 is also relevant. As shown in the drawing, both processors 3, 4 have independent voltage supply lines 18, 19 which are connected to the on-board voltage source 22 via separate voltage converters 20, 21.
  • the voltage converters 20, 21 reduce the on-board voltage from 12 V to an operating voltage of 5 V for the processors 3, 4, for example.
  • a switchover and isolating element 23 serving for short-circuit protection can be used to switch back and forth between the two lines 27, 28, so that the voltage supply for the subsequent switching can be ensured.
  • further safety functions can optionally be present, as shown in broken lines in FIG. 1.
  • this is a separate function monitoring circuit in the form of a customary watchdog circuit 24, which is independent of the function processor 4 and which, in particular in the event of a failure of the function processor 4, ensures that the speed step control processor 3 is still reliably monitored.
  • the selection range sensor 8 can be monitored for proper functioning by feedback of its signal output 9 via an A / D converter 25 to the function processor 4.
  • the output signal of the selection range sensor 8 is thus fed back to both control processors 3, 4, which can be used to check whether both processors are supported by the
  • control device 6 of the actuator 7 can be deactivated by the function processor 4, for example.
  • a plausibility check can be carried out between the gear selection and the selection range. For example, if the driver has selected the P or R selection ranges, no gears above the second gear should be selected.
  • the function processor 4 which forms the core of the present invention
  • the function processor 4 upon detection of a fault in the control processor 3, the latter is deactivated by the function processor 4 in exactly the same way as the control device 6 of the actuator 7 via the control line 26 Deactivation can bring the transmission itself into the default position already mentioned at the beginning, in which emergency operation takes place, for example with a permanently engaged second gear.
