Abstract

A vehicle safety system is disclosed that monitors vehicle surroundings, operational conditions, etc., in order to identify potential safety concerns or hazardous operational conditions. In doing so, the vehicle safety system collects data from one or more sources, such as sources that generate data from the vehicle itself (e.g., internal sensors), sources that generate data from the surroundings of the vehicle (e.g., external sensors), and sources that receive data from local or remote locations with respect to the host vehicle (e.g., a satellite, telematics, cellular, short or long range RF, etc., data acquisition unit). In response to data collected by components of the system, the system may use a hierarchical system to address the potential hazardous conditions or safety concerns.

Claims

1. A method of avoiding a hazardous condition between a first vehicle and a second vehicle, each having a safety system capable of transmitting and receiving safety data, the method comprising the steps of:

monitoring a set of vehicle safety data of the first vehicle, the set of safety data being obtained by a plurality of sensors associated with the first vehicle;

determining at the first vehicle the presence of a vehicle maneuver of either the first or second vehicle that may result in a hazardous condition;

receiving vehicle safety data from the second vehicle in proximity of the first vehicle corresponding to the first vehicle maneuver;

processing the received data and/or the set of first vehicle safety data, the processed data indicating the presence of a hazardous condition; and

signaling the vehicle operator of the first vehicle and/or the second vehicle of the hazardous condition.

2. The method of claim 1, further comprising the step of transmitting a request for safety data from a vehicle in proximity of the first vehicle corresponding to the first vehicle maneuver.

3. The method of claim 1, further comprising the step of controlling the first vehicle to obviate or reduce the severity of the hazardous condition.

4. The method of claim 1, further comprising the step of transmitting to the second vehicle and/or other vehicle, safety data representative of at least the action taken to control the first vehicle to obviate or reduce the severity of the hazardous condition.

5. The method of claim 3, wherein controlling the first vehicle includes brake control, steering control, engine control, and/or combinations thereof.

6. The method of claim 1, wherein the plurality of sensors are selected from a group consisting of radar, lidar, optical sensors, ultrasonic sensors, active and passive infrared sensors, radio frequency (RF) sensors, camera sensors, brake sensors, a throttle sensor, a suspension sensor, tire pressure sensors, vehicle inertial sensor(s), a wheel speed sensor, a vehicle speed sensor, a seat belt sensor, accelerometers, and a steering angle sensor.

7. A method of avoiding a hazardous condition between a first vehicle trailing a second vehicle, each having a safety system capable of transmitting and receiving safety data, the method comprising the steps of:

monitoring a set of safety data of the first vehicle, the set of safety data being generated by a plurality of sensors associated with the first vehicle;

receiving safety data from the second vehicle indicative of deceleration;

processing the received data in conjunction with the set of first vehicle safety data, the processed data indicating the presence of a hazardous condition; and

transmitting a signal to the vehicle operator of the second vehicle of the hazardous condition created by the safety data received by the first vehicle so that corrective action can be taken by the second vehicle.

8. The method of claim 7, further comprising controlling the first vehicle to obviate or reduce the severity of the hazardous condition.

9. The method of claim 8, wherein controlling the first vehicle includes brake control, steering control, engine control, and/or combinations thereof.

10. The method of claim 7, further comprising the step of alerting the operator of the first vehicle of the hazardous condition via one or more output devices.

11. The method of claim 10, wherein the output device is selected from a group consisting of audible devices, visual devices, and haptic devices.

12. The method of claim 7, wherein the plurality of sensors are selected from a group consisting of radar, lidar, optical sensors, ultrasonic sensors, active and passive infrared sensors, radio frequency (RF) sensors, camera sensors, brake sensors, a throttle sensor, a suspension sensor, tire pressure sensors, vehicle inertial sensor(s), a wheel speed sensor, a vehicle speed sensor, a seat belt sensor, accelerometers, and a steering angle sensor.

13. The method of claim 8, further comprising the step of transmitting a signal to the second vehicle indicative of the action taken by the first vehicle.

14. A method of avoiding a hazardous condition between a first vehicle trailing a second vehicle, each having a safety system capable of transmitting and receiving safety data, the method comprising the steps of:

monitoring a set of safety data of the first vehicle, the set of safety data being generated by a plurality of sensors associated with the first vehicle;

receiving safety data from the second vehicle indicative of deceleration;

processing the received data in conjunction with the set of first vehicle safety data, the processed data indicating the presence of a hazardous condition; and

transmitting a signal to the vehicle operator of the first vehicle of the hazardous condition created by the safety data so that corrective action can be taken by the first vehicle.

15. The method of claim 14, further comprising the step of transmitting a signal to the vehicle operator of the second vehicle of the hazardous condition so that corrective action can be taken by the second vehicle.

16. The method of claim 14, wherein the signal to the vehicle operator of the first vehicle of the hazardous condition is an audible, visual, and/or haptic signal.

17. The method of claim 14, further comprising the step of controlling the first vehicle to obviate or reduce the severity of the hazardous condition.

18. The method of claim 17, wherein controlling the first vehicle includes brake control, steering control, engine control, and/or combinations thereof.

19. The method of claim 14, further comprising the step of transmitting a signal to the second vehicle indicative of the action taken by the first vehicle.
