Method Of Comparing Roadway Signs With Vehicle State

Roadway signs provide critical information to drivers. Drivers must manually observe these signs while driving to extract their meaning and react accordingly. Some prior art recognizes roadway signs and displays them inside the vehicle, but the driver is responsible for comparing the sign information to vehicle state in order to react accordingly. The prior art fails to compare roadway sign information to vehicle state in order to emphasize signs that are particularly relevant to the driver.

Disclosed is a method of comparing external roadway signs to a vehicle's state and operation to provide alerts to the driver or emphasize particularly relevant signs.

In the preferred embodiment, a vehicle is driving down a road with roadway signs conveying road information such as upcoming points of interest, upcoming turns and exits, speed limits, etc. Using prior art as enabling technology, the vehicle actively recognizes the signs that it passes. Using vehicle diagnostics, the vehicle compares incoming sign information to vehicle state, such as remaining fuel, duration of non-stop driving, speed etc. Sign information is compared to vehicle state to provide relevant alerts.

Examples:


• Vehicle is being driven on the interstate, and the low gas indicator is enabled. The vehicle passes an information sign with a gas symbol and the system alerts the driver to the upcoming gas station.


• Vehicle has been driving on the interstate for five continuous hours. The vehicle passes an information sign with a rest stop symbol and then the system alerts the driver to the upcoming rest stop.


• The vehicle is being driven on the interstate at 77 MPH when it pas...
