    摘要: An electronic control apparatus for vehicles has at least two microcomputers, each having a non-volatile flash memory which stores a vehicle control program and data. Each microcomputer is reset when an abnormality is detected. Each microcomputer is applied with an identification signal indicative of a main one or sub one. When a data rewriting instruction is applied from an external writing device, one microcomputer which receives the identification signal indicative of the main one operates to release the other microcomputer from the reset condition after an elapse of a delay time period. A new control program and data transmitted from the external writing device is written into the corresponding flash memory in place of the previously stored control program and data.

    摘要: The control unit, especially a motor vehicle control unit, includes a microcomputer (13), a programmable nonvolatile memory (14) connected with or integrated in the microcomputer (13), a serial interface (15) for the microcomputer (13) to which a serial data transmission line (12) can be connected over which data for programming the programmable nonvolatile memory (14) is received in the microcomputer from an external programming unit (11), and a low pass filter connected to a terminal (16) for the serial data transmission line. The low pass filter includes components that produce a signal for enabling the programming of the programmable nonvolatile memory (14) of the external programming unit is connected to the control unit via the serial data transmission line (12). These components preferably include a first resistor (R2) connected between the terminal (16) and a programming-enabling input (19) of the microcomputer (13), a capacitor (C1) connected between the programming-enabling input (19) and ground and a second resistor (R1) connected to ground between the capacitor (C1) and the programming-enabling input.

    摘要: A device for controlling technical installations and machines, particularly combustion engines in motor vehicle, is proposed, having at least one microprocessor, at least one permenently programmed memory, and at least one freely programmable memory, in which vehicle-specific data, retrieval codes of the data, and at least one address pointer can be input into the freely programmable memory (6). Further proposed is a control scheme according to which are stored, in the freely programmable memory, first the data, then the associated retrieval codes and finally an address pointer which contains the addresses of the data.
