摘要
A warning system for vehicles detects actual road surface temperature and advises the driver of surface temperatures which indicate the vehicle may be approaching possible ice formation on roadways. The warning system comprises an infrared detector mounted externally on the vehicle and aimed at the road surface, the detector arranged to read only the infrared temperature wavelength emissions associated with concrete and asphalt to eliminate confusing and erroneous readings inadvertently received through infrared emission from other objects in the vicinity. The detector is connected to a processing unit which translates the electric signals from the detector into a temperature readout display for the driver and the processing unit may include an alarm which is activated to attract the driver's attention when road temperatures are detected that are below a set minimum temperature that is selected by the driver's manual adjustment of a temperature select control knob on the unit.
