Abstract:
A drive and steering control system for an endless track vehicle such as a sugar cane harvester. A dual path hydrostatic drive has a pair of variable volume pumps connected for bidirectional flow to respective hydraulic motors driving a pair of endless tracks. A speed control lever and steering wheel mechanism each provide control inputs to a microprocessor which in turn controls the variable volume hydrostatic pumps to control vehicle velocity and turning in a way that matches control for wheeled vehicles. RPM sensors for the hydraulic motors provide a feedback signal that is used to compensate for equipment variation and to keep the vehicle on the course intended by the operator.
