Abstract
A control system for a vehicle having a plurality of subsystems in which each subsystem includes a sensor and/or actuator. A general purpose processor is programmed with a plurality of software applications in which each software application is associated with one of the vehicle subsystems. The subsystems and processor communicate with each other through an electrical bus and each subsystem includes a communication interface to receive commands from the processor as well as to send task signals to the processor. A task arbitrator prioritizes the order of execution of multiple task signals received by the processor during a preset time period. The general purpose processor then initiates execution of the software application associated with the subsystem of the sensor signal received from the task arbitrator and thereafter transmits a control signal to one or more of the subsystems via the bus as a result of execution of the associated software application.
