Abstract
A light detection and ranging system 100 for use with a vehicle 500. The system includes a transmitter 102 configured to transmit three transmission wavelengths nominally in a range from 800 nm to 1700 nm. A receiver is configured to receive three reflected signals 114, each of the three reflected signals 114 being a portion of an associated one of the three transmission wavelengths reflected to the receiver 104 from a roadway object 112. A controller 106 provides a categorization output in response to comparing reflectance values of the three reflected signals 114 to categorize the roadway object 112 into one of a plurality of pre-defined material-type categories. A method of controlling the travel of a vehicle based on a categorization output from a controller 106 is also provided.
