Computer unit for a control device in a motor vehicle

摘要

The computing unit generates an output signal for controlling a function of the motor vehicle. The processing specification that is stored in a ROM of the computing unit, and with which, in particular, a logic function is described, can be changed even after the ROM mask has been created. Instead of the logic function, a truth table which represents the logic function is stored in an EPROM of the computing unit. A processing specification is stored in the ROM with which calculated variables are compared with the truth table.
