摘要： A method is proposed for optimising data and/or program parts for programmed control units, which can be used in the application of motor vehicle control units. The method involves connecting the control unit (10) via an interface (SSO) to an external applications device (11) which is used to enter the requisite modifications to the data and/or program parts to be optimised. The proposed method is characterized by the fact that at the start of the optimisation process the data and/or program parts to be optimised are located into the data and/or program ramdom access memory (RAM) of the control unit (10). The method is further characterized by the fact that specific modifications are made in the control program and/or the memory- and/or register spaces in the control unit (10), as a result of which the microcomputer ( mu P, 12) of the control unit (10), instead of accessing the data and/or program parts in the data and/or program ROM (flash-EPROM), accesses the corresponding data and/or program parts in the data and/or program random access memory (RAM). It is proposed, for a control unit used for implementing this method, that a decoder circuit (41) should be provided in the control unit (10); that circuit effects a switching operation whenever the microcomputer (40) accesses a particular address or address region. The switching operation ensures that the microcomputer (40), instead of accessing the data and/or program parts in the data and/or program ROM (42), accesses the corresponding data and/or program parts in the data and/or program random acess memory (43).

摘要： Dans le procédé décrit, la tension de seuil n'est plus fixée à une valeur prédéterminée avec précision, au moyen d'une source de tension de référence très précise. Au lieu de cela, une contre-tension est connectée en opposition à la tension de la sonde et mesurée, et la ou les tensions de seuil sont mises en corrélation avec la valeur mesurée dont la valeur absolue ne doit pas être nécessairement connue. Ce procédé permet de se dispenser d'une source de tension de référence très précise et de résistances de haute précision. Celles-ci sont remplacées dans le dispositif décrit par un moyen de mesure de la contre-tension et un moyen pour mettre en corrélation les tensions de seuil avec la contre-tension.

摘要： Proposed is an electronic control unit and a device for programming it. Provided for programming the non-volatile memory (14) of the control unit (10) is an external programming device (11) which is connected to the control unit (10) by a serial-transfer line (12). The programming device (11) transfers the programming data to the control unit (10) via the transfer line. The programming device (11) also transfers to the control unit (10) the release signal for programming of the non-volatile memory (14). The control unit (10) is characterized in that it includes means which recognize the programming-release signal when the programming device (11) is connected via the transfer line (12) to the control unit (10).

摘要： In the process disclosed, the threshold voltage is not fixed at an accurately predetermined value using a high-precision reference voltage source. Instead, a countervoltage connected in opposition to the sensor voltage is measured and the threshold voltage(s) is(are) correlated with the measured value the absolute value of which need not be known. This process makes it possible to dispense with a high-precision reference voltage source and with high-pression resistors. These are replaced in the device according to the invention by a means for measuring the countervoltage and a means for correlating threshold voltages with the countervoltage.

摘要： Disclosed is a process for the protection of stored program controls, especially in motor vehicles, offering software protection for the programming. The program routine for the programming is divided up into sections by an external device, so that inquiries into program release can be effected between the individual sections.

摘要： A microcomputer (10) is proposed, which includes a central processing unit (11), a non-volatile memory (13), a volatile memory (14), a monitoring circuit (12) and also an input/output unit (16). Two different operating states are possible in the microcomputer (10). In the first operating state, the microcomputer executes a program which is located in the non-volatile memory (13). In the second operating state, the microcomputer (10) executes a program which is located in the volatile memory (14). The monitoring circuit (12) effects a resetting of the microcomputer (10) whenever it does not receive a monitoring signal for a predetermined time (watchdog timer). The microcomputer is distinguished in that it includes an element for suppressing monitoring signals which are always active whenever the microcomputer (10) is operating in the second operating state.
