Abstract

The present invention relates to a microprocessor arrangement for use in a vehicle control system which includes a plurality of microprocessor systems that are linked by bus systems and perform at least anti-lock control (ABS) and/or traction slip control (ASR) and at least one other high-computation control function, such as yaw torque control (GMR), and monitoring functions. The microprocessor arrangement includes three microprocessor systems to which the individual functions are allocated so that the first microprocessor system along with the second microprocessor system performs the ABS and ASR functions, including the monitoring of these functions, and that the third microprocessor system along with the second microprocessor system performs the other control function (GMR), including its monitoring.
