Abstract: A method is provided for detecting faults in an electronically controlled drive system of a motor vehicle by way of an electronic control unit. The electronic control unit detects at least the accelerator pedal position and the longitudinal acceleration of the motor vehicle as input signals. The control unit is configured to carry out a first fault detection program independently of its actual functional scope, by which program, a fault is detected if a defined acceleration gradient, which is dependent on a change in the accelerator pedal position, is exceeded for longer than for a predefined time period.

Abstract: A method of operating a processor bus, with which a central unit (processor) makes accesses to various peripheral units, is described. The processor bus has the ability to change the order of the accesses as a function of the operating state of the peripheral units, and the peripheral units can either reject or delay the access.

Abstract: A circuit includes a built-in self-test, wherein the test coverage of a tested logic circuit is improved given the utilization of a fixed standard interface. Besides a direct interface, the complex circuit has an additional indirect interface, which connects a structural test device to a functional circuit.
