## Abstract

A driver warning system automatically detects the existence of in-the-road, passable obstructions and provides timely notification to a driver in proximity of such an in-the-road, passable obstruction prior to it being encountered with sufficient warning time for the driver to avoid the in-the-road, passable obstruction. To detect in-the-road, passable obstructions, the warning unit of a driver whose vehicle hits an in-the-road, passable obstruction will automatically generate a signal that is indicative of the existence of the in-the-road, passable obstruction and its location. This signal may be transmitted to a server, which contains a database of located obstructions. The collected information about the detected in-the-road, passable obstructions are provided to various warning units, so that they, knowing the driver location, e.g., based on global positioning system (GPS), can provide the driver with a warning of any upcoming in-the-road, passable obstructions with sufficient lead time for the driver to avoid hitting the obstruction.

## Claims

### Claim 1

An apparatus for use in avoiding an in-the-road, passable obstruction, comprising:
a memory storing an indication of the existence of an in-the-road, passable obstruction;
a database for in-the-road, passable obstructions;
a receiver for receiving a first signal from a set of signal types consisting of audio signals and accelerometer signals indicative of the first obstruction to be added to said database;
at least one first processor for determining if the first signal indicates the first obstruction, the at least one first processor supplying as an output a second signal indicative of the existence of said in-the-road, passable obstruction when a vehicle comes within a proximity of said in-the-road, passable obstruction prior to encountering said in-the-road, passable obstruction; and wherein the at least one first processor second signal further indicates a classification of said in-the-road, passable obstruction, the at least one first processor further supplying as an output a suggested overt action for a driver of said vehicle to take to avoid said in-the-road, passable obstruction.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising:
a receiver for receiving from a server said indication of the existence of said in-the-road, passable obstruction.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein said at least one first processor generates the second signal to be perceivable by a human being.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein said at least one first processor further supplies as an output an advertisement in conjunction with supplying said second signal indicative of the existence said in-the-road, passable obstruction.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein said apparatus further comprises a location determiner that supplies a current location of said vehicle to said at least one first processor.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising:
a human input unit adapted to receive input from a human being indicating that said in-the-road, passable obstruction was not present.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein said memory further stores the location of said in-the-road, passable obstruction.

### Claim 8 (depends on 1)

The apparatus of claim 1, wherein said apparatus comprises memory, coupled to said at least one first processor, that stores map information for use by said at least one first processor.

### Claim 9 (depends on 1)

The apparatus of claim 1, wherein said second signal generated by said at least one first processor is supplied to an automated control device of said vehicle that is configured to adjust the travel of said vehicle.

### Claim 10

An in-the-road, passable obstruction server, comprising:
a database for in-the-road, passable obstructions; and
a transmitter for transmitting at least a subset of said in-the-road, passable obstructions toward a user equipment of the in-the-road, passable obstruction warning system,
wherein an at least one first processor further supplies as an output a signal indicating a classification of a first obstruction of the subset of an in-the-road, passable obstructions, the at least one first processor further supplying as an output a suggested overt action for a driver of said vehicle to take to avoid said in-the-road, passable obstruction;
a receiver for receiving signals from a set of signals consisting of at least one of audio signals and accelerometer signals indicative of the first obstruction to be added to said database; and
a processor for determining if said signals indeed indicate the first obstruction.

### Claim 11 (depends on 10)

The in-the-road, passable obstruction server of claim 10, wherein said in-the-road, passable obstruction server further comprises:
a receiver for receiving an indication of the first obstruction of the subset of the in-the-road passable obstructions to be added to said database.

### Claim 12 (depends on 10)

The server of claim 10, wherein said in-the-road, passable obstruction server further comprises a receiver for receiving a request to transmit at least said subset of said in-the-road passable obstructions, and wherein said transmitter is responsive to said received request to transmit said subset.

### Claim 13 (depends on 10)

The server of claim 10, wherein said subset of said in-the-road, passable obstructions is determined based upon one of a group consisting of a current location of a user equipment of the in-the-road, passable obstruction warning system, a current location of said user equipment in-the-road, passable obstruction warning system and a prescribed radius, and locations along an anticipated route of travel of said a current location of said user equipment in-the-road, passable obstruction warning system.

### Claim 14 (depends on 1)

The apparatus of claim 1, wherein the at least one first processor uses a threshold to determine the existence of the in-the-road, passable obstruction, the threshold being based in part on a characterization of the vehicle.

### Claim 15 (depends on 14)

The apparatus of claim 14, wherein the characterization of the vehicle includes at least one of a physical characteristic of the vehicle and a speed of the vehicle, wherein the physical characteristic of the vehicle includes at least one of vehicle suspension information, vehicle weight information, vehicle size information, and vehicle tire size information.

### Claim 16 (depends on 10)

The in-the-road, passable obstruction server of claim 10, wherein the set of signals consists of both the audio signals and the accelerometer signals indicative of the first obstruction to be added to the database.

### Claim 17 (depends on 13)

The in-the-road, passable obstruction server of claim 13, wherein the subset of said in-the-road, passable obstructions is determined based upon the current location of the user equipment of the in-the-road, passable obstruction warning system and the prescribed radius.

### Claim 18 (depends on 9)

The apparatus of claim 9, wherein the automated control device is one of a suspension system and a cruise control system that are capable of adjusting the travel of the vehicle based on the at least one first processor.
