Abstract

A vehicle collision avoidance system that utilizes signal emitters and receivers positioned around the periphery of vehicles to detect nearby vehicles. Upon detection of a nearby vehicle, the system may execute any of a variety of predefined responses based on the distance from the local vehicle to the detected nearby vehicle.

First claim

We claim:

1. A method for a subject vehicle to avoid collisions with a different vehicle comprising:
emitting signals from a plurality of signal emitters positioned around the periphery of a subject vehicle such that signals are emitted within a predetermined range;
receiving one or more inbound signals emitted from a different vehicle with one or more signal receivers positioned around the periphery of the subject vehicle;
determining a distance from the subject vehicle to the different vehicle upon receipt of the one or more inbound signals at a location of a signal receiver that received the one or more inbound signals; and,
executing any of a variety of predefined collision avoidance actions, separately or in combination, based on the determined distance or distances from the subject vehicle to the different vehicle.

2. The method of claim 1 in which said signals are any of: laser light beams, infrared light beams, radio waves, and ultrasound waves.

3. The method of claim 1 in which said predefined collision avoidance actions include any of: countersteering, applying a haptic alert, emitting a sound alert, displaying a visual alert, reducing speed, and increasing speed.

4. The method of claim 3 in which countersteering comprises:
in a first step, determining whether said distance from the subject vehicle to the different vehicle is less than a predetermined threshold;
in a second step, if said distance is less than said predetermined threshold, determining a second distance to a nearest obstacle on a side of the subject vehicle opposite of a side on which said different vehicle was detected; and,
in a third step, if said second distance is greater than a predetermined threshold, adjusting the steering position of the subject vehicle a predetermined amount, in a direction opposite of a side on which said inbound signal or signals were received, for a predetermined length of time.

5. A system for avoiding vehicular collisions comprising:
a plurality of signal emitters positioned around the periphery of a subject vehicle such that signals may be emitted within a predetermined range;
a plurality of signal receivers positioned around the periphery of the subject vehicle such that inbound signals emitted from a different vehicle within a predetermined field may be received;
and,
one or more predefined collision avoidance actions corresponding to one or more vehicle to vehicle distance thresholds;

whereby, upon receipt of one or more inbound signals from a different vehicle, the subject vehicle:
determines the distance from the subject vehicle to a different vehicle at a location of a signal receiver that received one or more inbound signals; and
executes the one or more collision avoidance actions corresponding to a distance from the subject vehicle to the different vehicle.

6. The system of claim 5 in which said signals are any of: laser light beams, infrared light beams, radio waves, and ultrasound waves.

7. The system of claim 5 in which said predefined collision avoidance actions include any of: countersteering, applying a haptic alert, emitting a sound alert, displaying a visual alert, reducing speed, and increasing speed.

8. The system of claim 7 in which countersteering comprises:
in a first step, determining whether the distance from the subject vehicle to the different vehicle is less than a predetermined threshold;
in a second step, if said distance is less than said predetermined threshold, determining a second distance to a nearest obstacle on the side of the subject vehicle opposite of the side on which the different vehicle was detected; and,
in a third step, if said second distance is greater than a predetermined threshold, adjusting the steering position of the subject vehicle a predetermined amount, in a direction opposite of the side on which said inbound signal or signals were received, for a predetermined length of time.
