ABSTRACT:
A system for controlling autonomous operation of a vehicle in response to speed and steering angle request signals from a navigator allows manual operation of the vehicle. The system includes a machine control module, an engine control module, and a transmission control module. An auto/manual select signal indicates to the machine control module whether operation should be in a fully autonomous mode or a manual mode. In the autonomous mode, a navigator produces a speed request signal and a steering angle request signal for the vehicle. The machine control module receives the speed and steering angle request signals from the navigator. From these inputs, the machine control module produces an engine RPM (revolutions per minute) control signal for the engine control module, a transmission control signal for the transmission control module, a brake control signal, and a steering angle control signal. In the manual mode, the machine control module will not interfere with normal, manual (i.e., manned) control of all vehicle systems.
