Abstract

A communication system for vehicles includes a first communication device disposed at a first vehicle and a second communication device disposed at a second vehicle. The first communication device wirelessly transmitting data indicative of a predicted path of travel of the first vehicle, and the second communication device receives the transmitted data from the first communication device. A control of the second vehicle processes data received from the first communication device and data indicative of a predicted path of travel of the second vehicle to determine a potential collision between the first vehicle and the second vehicle during a turning maneuver of one of the first and second vehicles toward the other of the first and second vehicles. Responsive to determination of a likelihood of collision between the first vehicle and the second vehicle, the control generates an alert to a driver of the second vehicle.

Claims

wherein said first and second communication devices comprise first and second dedicated short range communication (DSRC) devices;

a control of the second vehicle, wherein said control (i) processes data indicative of the predicted path of travel of the first vehicle that is wirelessly transmitted from said first communication device at the first vehicle and received at said second communication device at the second vehicle, and (ii) processes data indicative of a predicted path of travel of the second vehicle;

wherein, responsive to processing data indicative of the predicted path of travel of the first vehicle and processing data indicative of the predicted path of travel of the second vehicle, said control determines a potential collision between the first vehicle and the second vehicle during a turning maneuver of the truck toward the other of the first and second vehicles; and

wherein, responsive to determination of a likelihood of collision between the first vehicle and the second vehicle, said control generates an alert to a driver of the second vehicle.

2. The communication system of claim 1, comprising an exterior viewing camera of the first vehicle, wherein said first communication device wirelessly transmits image data captured by said exterior viewing camera, and wherein the determination of a potential collision between the first vehicle and the second vehicle is based at least in part on processing by said control of received captured image data.

3. The communication system of claim 1, comprising an exterior viewing camera of the second vehicle, wherein the determination of a potential collision between the first vehicle and the second vehicle is based at least in part on processing by said control of received image data captured by said exterior viewing camera.

4. The communication system of claim 1, wherein the first vehicle is a car and the second vehicle is the truck.

5. The communication system of claim 4, wherein said control determines a potential collision between the first vehicle and the second vehicle when the truck is making a turning maneuver towards a region occupied by the car or in the predicted path of travel of the car.

6. The communication system of claim 1, wherein the second vehicle is a car and the first vehicle is the truck.

7. The communication system of claim 6, wherein said control determines a potential collision between the first vehicle and the second vehicle when the truck is making a turning maneuver towards a region occupied by the car or in the predicted path of travel of the car.

8. The communication system of claim 1, wherein, responsive to determination of a likelihood of collision between the first vehicle and the second vehicle, said control controls the brake system and/or steering of the second vehicle.

9. The communication system of claim 1, wherein the predicted path of travel of the first vehicle is determined based on the current steering angle of the first vehicle.

10. The communication system of claim 1, wherein the predicted path of travel of the second vehicle is determined based on the current steering angle of the second vehicle.
