Abstract
A material feed system for a paving machine includes a first optical sensor and a second optical sensor that are configured to generate data characteristic of paving material associated with corresponding ones of a left feed mechanism and a right feed mechanism of the paving machine. A controller is communicably coupled to the first optical sensor, the second optical sensor, a left conveyor, and a left auger of the left feed mechanism, and a right conveyor and a right auger of the right feed mechanism. The controller is configured to control the left material feed mechanism and the right material feed mechanism independently of each other such that the left conveyor and auger speeds are independently adjusted based on the data received from the first optical sensor and the right conveyor and auger speeds are independently adjusted based on the data received from the second optical sensor.
