Abstract: This disclosure describes the use of optical sensors to detect and characterize the state of traffic lights to assist with the navigation of autonomous vehicles. In particular, a specific optical configuration is shown that includes both a fixed-exposure sensor and an auto-exposure sensor. Imagery from the two sensor types can be combined to more accurately characterize the state of traffic signals at any particular intersection. Systems and methods for analyzing only select regions of the imagery captured by the traffic light detection system are also described.

Abstract: The present disclosure is related to a method of controlling a machine having an engine, a hydraulic pump and an operator input device. The method includes storing operation data corresponding to multiple operating parameters of the machine over a predetermined number of working cycles. The operation data is compared with respective predetermined ranges of operating parameters. Further, the machine in controlled in a normal mode of operation if the stored operation data lies outside the respective predetermined ranges. Further, the machine is controlled in an override mode if the stored operation data lies within the predetermined ranges. In the override mode, the machine is controlled based on estimated values of the operating parameters. Further, the method includes switching to the normal mode if a current operator input lies outside a predetermined range of the operator input.
