Computer error monitoring method e.g. for motor vehicle electronic control and braking systems, involves transmitting reset pulse via signal lines when error state of computer unit is detected

摘要

A method of monitoring a computer system with first and second computing units (20,30) between which data and/or control signals are transmitted via first signal lines (6,8). When an error state of one of the computer units (20;30) is detected by the other computer unit (30;20) a reset pulse is transmitted from the other computer unit via second signal lines (12,10) to re-start afresh the one computer unit (20;30). During installation of the computer system (2), the latter is initialized by supplying a reset pulse (power-on-reset) to the computer units (20,30), and during the initialization process during installation of the computer system, the function of mutual starting of the computer units (20,30) afresh is checked for errors by transmitting reset pulses via the second signal lines (10,12). An Independent claim is given for a computer system with two computer units.
