Abstract
A circuit arrangement for a safety-critical control system, such as ABS, TCS, ASMS, brake-by-wire, etc., has a dual-circuit or multiple-circuit design, and each circuit includes a complete microprocessor system that processes the input data redundantly and delivers an error identification signal (FAIL) when an error or a discrepancy between the redundantly produced data processing results occurs. Upon error detection, there is a transition to an emergency operation mode where either a circuit is disconnected or the actuator activation of both circuits is assumed by the intact microprocessor system. Each of the two systems is equipped with peripherals of its own, comprised of signal detection, actuator activation, and energy supply.
