A method of sensor output configuration comprising:acquiring, for a sensor, sensor output specifications for a plurality of sensor clients, wherein a first sensor output specification for a first of said plurality of sensor clients defines a first value for a sensor parameter, wherein a second sensor output specification for a second of said plurality of sensor clients defines a second value for said sensor parameter, and wherein said first value and said second value are different;
based on said sensor output specifications for said plurality of sensor clients, configuring a sensor processing unit which includes said sensor to:
simultaneously provide an output of said sensor to said plurality of sensor clients according to said first value while a first operational condition is met; and
cease providing said output of said sensor according to said first value and switch to simultaneously providing said output of said sensor to said plurality of sensor clients according to said second value while a second operational condition is met, wherein said first operational condition and said second operational condition are different, and wherein as part of said switch said sensor processor unit adjusts sensor operation by changing said sensor parameter from said first value to said second value.

CALIBRATION FIXTURE FOR RANGE FINDING SENSORS ON A VEHICLE

Hunter Engineering Compan...

1. A calibration fixture for use in the alignment, calibration, or inspection of a sensor onboard a vehicle having an external field of view into which the sensor is configured to project an emitted signal and from which the sensor is configured to receive a return signal, comprising:a support structure for positioning at a first calibration distance from said vehicle within the field of view of said sensor; and
at least one calibration component disposed on said support structure, said calibration component configured to transform an emitted signal from said sensor into a return signal by conveyance along a non-linear signal pathway from a signal entry to a signal exit, said non-linear signal pathway comprising only passive elements altering a travel direction of said emitted signal such that said return signal appears to said sensor as if said at least one calibration component was positioned at a predetermined linear calibration distance from said vehicle which is greater than said first calibration distance.

TRAFFIC LIGHT STATE ASSESSMENT

GM GLOBAL TECHNOLOGY OPER...

1. An autonomous driving system, comprising:a controller comprising at least one processor and memory, the memory comprising:
a guidance system configured to receive semantic map data and to calculate route data using the semantic map data, via at least one processor;
wherein the semantic map data includes traffic light location data, wherein the semantic map maps an intersection using a plurality of labelled intersection lanes defining paths for traversing the intersection, wherein each labelled intersection lane includes a traffic light label defining traffic light location data, and wherein traffic light labels of at least some of the labelled intersection lanes identify different traffic lights from each other;
a computer vision system configured to view and assess a state of a traffic light based on the traffic light location data, via the at least one processor; and
a vehicle control system configured to control driving of an autonomous vehicle based at least on the route data and the state of the traffic light, via the at least one processor.
