  • the invention relates to an electronic control unit for motor vehicles, the basic equipment of which in particular comprises a central unit, a program memory, a data memory and an input / output unit with a plurality of input and output channels.
  • Electronic control systems of motor vehicles are used in practice to perform a wide variety of different tasks, and depending on the vehicle type, drive unit and basic and additional equipment or units, only a certain combination of all possible areas of activity is required to cover the individual motor vehicle embodiment variant.
  • Warehousing and handling in production and customer service are correspondingly complicated.
  • the invention has for its object to provide an electronic control unit of the type mentioned that Probably in production as well as in service, as many different design variants of motor vehicles as possible can be adapted quickly and reliably in a simple manner.
  • a code memory for at least one code word for determining the respective individual embodiment variant is assigned to the basic equipment which can be designed simultaneously for several different individual embodiment variants, and in that the associated program sections, data records, input and / or output channels as a function of the respective contents of the code memory can be controlled.
  • the input and / or output channels can be implemented, for example, by special circuits.
  • the electronic control device can have a uniform hardware, a uniform program and / or uniform data records for all different design variants that are appropriately equipped. Additional, space-consuming components are not required for an expansion of the functions or input / output circuits that may be required.
  • the first bit 0 alternatively controls a load control via an absolute pressure sensor or a load control via a load signal from the air quantity meter of the injection system.
  • the second bit 1 of the code word alternatively activates an idling control with a speed and load-dependent idling characteristic or an idling control with an idling contact selection.
  • Bit 2 of the code word determines whether a fuel cut-off control should preferably be activated with an ignition angle change limitation or not.
  • Bit 3 of the code word provides an alternative choice between an ignition control with two maps (16 x 16) with load gradient-dependent switching and an ignition control with a map (32 x 16) with an assigned idling characteristic.
  • Bit 4 determines whether control with gearbox intervention or without gearbox intervention should take place.
  • bit 5 With a logic level 1 of bit 5 is a function variant with electronic Ab gas recirculation can be activated.
  • the code word bit 6 determines whether or not a dynamic adaptation is carried out.
  • the last bit 7 of the code word can indicate whether a Hall release or an inductive crankshaft release is used to determine the speed. In the example described, the remaining functions are always activated regardless of the respective code word.
  • control units can be equipped for several, but only for a part of the overall possible design variants. With such an assembly, for example, the design variants are taken into account that roll off the assembly line in the relevant production line.
  • the control units supplied to the conveyor can either be on the conveyor - i.e. near the belt, but regardless of the cycle time - can be programmed with the possible data records. However, they can also be delivered ready-programmed.
  • the code word specific to the vehicle version is entered into the code memory in order to control or release the appropriate special control unit version.
