Abstract
Abstract A vehicle collision warning system includes a distance measuring device for measuring a distance from a subject vehicle to an obstacle in front of the subject vehicle, a speed detecting device for detecting a speed of the subject vehicle, a control device for receiving signals from the distance measuring device and the speed detecting device and estimating a possibility of collision to the obstacle based on the received signals, and an alerting device electrically connected to the control device. When the control device determines that there is a possibility of collision, the alerting device receives a signal from the control device and emits a first alarm to the subject vehicle and provides a second alarm to a following vehicle without awaiting an action of a driver of the subject vehicle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
A vehicle collision warning system, comprising: distance measuring means for measuring a distance from a subject vehicle to an obstacle in front of the subject vehicle; speed detecting means for detecting a speed of the subject vehicle; control means electrically connected to the distance measuring means and the speed detecting means for receiving signals from the distance measuring means and the speed detecting means, said control means estimating a possibility of collision to the obstacle based on the received signals; and alerting means electrically connected to the control means, said alerting means, when the control means determines that there is a possibility of collision, receiving a signal from the control means, emitting a first alarm to the subject vehicle and providing a second alarm to a following vehicle without awaiting an action of a driver of the subject vehicle, said second alarm being a signal sending to the following vehicle for increasing tension of a seat belt of the following vehicle.
Claim 2
Dependent Claim
161 words
A vehicle collision warning system, comprising: distance measuring means for measuring a distance from a subject vehicle to an obstacle in front of the subject vehicle; speed detecting means for detecting a speed of the subject vehicle; control means electrically connected to the distance measuring means and the speed detecting means for receiving signals from the distance measuring means and the speed detecting means, said control means estimating a possibility of collision to the obstacle based on the received signals; and alerting means electrically connected to the control means, said alerting means, when the control means determines that there is a possibility of collision, receiving a signal from the control means, emitting a first alarm to the subject vehicle and providing a second alarm to a following vehicle without awaiting an action of a driver of the subject vehicle, said second alarm being a signal sending to the following vehicle for increasing tension of a seat belt of the following vehicle.
Claim 3
Dependent Claim
23 words
A vehicle collision warning system according to claim 1 , wherein said distance measuring means utilizes millimeter wave, laser radiation, or ultrasonic wave.
Claim 4
Dependent Claim
68 words
A vehicle collision warning system according to claim 1 , wherein said second alarm to the following vehicle additionally includes at least one means selected from the group consisting of lighting a stop lamp of the subject vehicle, lighting a hazard lamp of the subject vehicle, alerting through radio communication to the following vehicle, and sending a signal to the following vehicle for automatically braking the following vehicle.
Claim 5
Dependent Claim
33 words
A vehicle collision warning system according to claim 3 , wherein said second alarm has levels of warnings selected in accordance with a degree of possibility of collision estimated by said control means.
Claim 6
Dependent Claim
80 words
A vehicle collision warning system according to claim 4 , wherein when it is estimated that a possibility of collision is medium, said alerting means emits a first level alarm including signals for lighting the stop lamp and alerting through the radio communication; and when it is estimated that the possibility of collision is high, said alerting means emits a second level alarm including signals for lighting the stop lamp and the hazard lamp, and alerting through the radio communication.
Claim 7
Dependent Claim
78 words
A vehicle collision warning system according to claim 1 , wherein said second alarm includes a first level alarm for providing a first tension to the seat belt of the following vehicle to notify that the following vehicle is approaching to an emergency situation, and a second level alarm for providing a second tension greater than the first tension to the seat belt of the following vehicle to notify that the following vehicle is in the emergency situation.
