Abstract
Abstract A vehicle warning system and method. A detector is onboard a first vehicle and automatically detects a travel condition problem encountered by the first vehicle at a first location. A vehicle position locator automatically determines the first location of the first vehicle. A communicator automatically transmits the determined first location and the detected travel condition problem to a second location. In one example, the vehicle is an automotive vehicle, and the second location is a communications center which transmits the determined first location and the detected travel condition problem (such as an icy roadway or a traffic jam) to only those other vehicles headed toward the first location.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
A method for warning a second vehicle of a travel condition problem encountered by a first vehicle at a first location comprising the steps of: a) receiving a vehicle operating parameter sensed by a vehicle sensor onboard the first vehicle; b) identifying the travel condition problem based at least in part on the received vehicle operating parameter; c) determining the first location of the first vehicle; d) determining the travel path of the second vehicle; and e) communicating the determined first location and the identified travel condition problem to the second vehicle only when the determined travel path of the second vehicle is headed toward the determined first location.
Claim 2
Independent Claim
109 words
A method for warning a second vehicle of a travel condition problem encountered by a first vehicle at a first location comprising the steps of: a) receiving a vehicle operating parameter sensed by a vehicle sensor onboard the first vehicle; b) identifying the travel condition problem based at least in part on the received vehicle operating parameter; c) determining the first location of the first vehicle; d) determining the travel path of the second vehicle; and e) communicating the determined first location and the identified travel condition problem to the second vehicle only when the determined travel path of the second vehicle is headed toward the determined first location.
Claim 3
Dependent Claim
126 words
A vehicle warning system comprising: a) a detector which is onboard a first automotive vehicle and which automatically detects a loss of traction event encountered by the first vehicle at a first location; b) a vehicle position locator which automatically determines the first location of the first vehicle; and c) a communicator which is onboard the first automotive vehicle and which transmits the determined first location and the detected low traction event to a communications center remote from the first automotive vehicle, wherein the communications center determines which other automotive vehicles are headed toward the determined first location and transmits the determined first location and the detected low traction event only to those other automotive vehicles which are determined to be headed toward the first location.
Claim 4
Dependent Claim
126 words
A vehicle warning system comprising: a) a detector which is onboard a first automotive vehicle and which automatically detects a loss of traction event encountered by the first vehicle at a first location; b) a vehicle position locator which automatically determines the first location of the first vehicle; and c) a communicator which is onboard the first automotive vehicle and which transmits the determined first location and the detected low traction event to a communications center remote from the first automotive vehicle, wherein the communications center determines which other automotive vehicles are headed toward the determined first location and transmits the determined first location and the detected low traction event only to those other automotive vehicles which are determined to be headed toward the first location.
Claim 5
Dependent Claim
66 words
The system of claim 2 , wherein the detector includes at least one vehicle sensor and a computer, wherein the at least one vehicle sensor is onboard the first vehicle and senses a vehicle operating parameter at the first location, and wherein the computer is onboard the first vehicle and detects the low traction event based at least in part on the sensed vehicle operating parameter.
Claim 6
Dependent Claim
24 words
The system of claim 3 , also including a temperature sensor, and wherein the computer determines the low traction event is an icy roadway.
Claim 7
Dependent Claim
48 words
The system of claim 2 , wherein the communications center transmits the determined first location and the detected low traction event to other locations only when a predetermined number of separate vehicles transmit a low traction event and substantially the same determined first location to the communications center.
Claim 8
Dependent Claim
124 words
A vehicle warning system comprising: a) a detector which is onboard a first automotive vehicle and which automatically detects a traffic jam event encountered by the first vehicle at a first location; b) a vehicle position locator which automatically determines the first location of the first vehicle; and c) a communicator which is onboard the first automotive vehicle and which transmits the determined first location and the detected traffic jam to a communications center remote from the first automotive vehicle, wherein the communications center determines which other automotive vehicles are headed toward the determined first location and transmits the determined first location and the detected traffic jam event only to those other automotive vehicles which are determined to be headed toward the first location.
Claim 9
Dependent Claim
124 words
A vehicle warning system comprising: a) a detector which is onboard a first automotive vehicle and which automatically detects a traffic jam event encountered by the first vehicle at a first location; b) a vehicle position locator which automatically determines the first location of the first vehicle; and c) a communicator which is onboard the first automotive vehicle and which transmits the determined first location and the detected traffic jam to a communications center remote from the first automotive vehicle, wherein the communications center determines which other automotive vehicles are headed toward the determined first location and transmits the determined first location and the detected traffic jam event only to those other automotive vehicles which are determined to be headed toward the first location.
Claim 10
Dependent Claim
66 words
The system of claim 6 , wherein the detector includes at least one vehicle sensor and a computer, wherein the at least one vehicle sensor is onboard the first vehicle and senses a vehicle operating parameter at the first location, and wherein the computer is onboard the first vehicle and detects the traffic jam event based at least in part on the sensed vehicle operating parameter.
Claim 11
Dependent Claim
17 words
The system of claim 6 , wherein the determined first location is along a limited access highway.
Claim 12
Dependent Claim
48 words
The system of claim 8 , wherein the communications center transmits the determined first location and the detected traffic jam event to other locations only when a predetermined number of separate vehicles transmit a traffic jam event and substantially the same determined first location to the communications center.
