Abstract
A drive system for utility vehicles, in particular for agricultural or industrial tractors, includes a generator driven by an internal combustion engine, a drive axle with wheels driven by associated electric motors which are powered by the generator, a steerable axle with wheels which are steerable together or individually by steering actuators, and manual operating control devices for vehicle operating functions such as steering and vehicle. The drive system includes a process computer which includes parallel and independently operating function modules for controlling high priority vehicle functions, such as steering, as well as function modules for low priority vehicle functions, such as speed input. The process computer transmits target value signals for actuator, such as electric wheel drive motors and steering actuators, in the form of a combined message communicated over a system bus. Information is exchanged between the function modules internally within the processor.
