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 vehicle safety system, comprising:

a plurality of sensors associated with a vehicle carrying a load, including one or more sensors capable of generating one or more of vehicle load position data, weight data, and center of gravity data;

at least one vehicle control device for controlling a selected vehicle operation; and

a controlling component in communication with the plurality of sensors for receiving generated thereby, and the vehicle control device, the controlling component being capable of receiving signals generated from the plurality of sensors, and determining an impending hazardous vehicle operational state based on the generated data and vehicle path data.

2. The vehicle safety system of claim 1, further comprising an output device for alerting the vehicle operator of the impending hazardous vehicle operational state.

3. The vehicle safety system of claim 2, wherein the output device is selected from a group consisting of audible devices, visual devices, and haptic devices.

4. The vehicle safety system of claim 2, further comprising at least one operator input device, wherein the controlling component controls the vehicle control device if no corrective input from the operator input device is detected by the controlling component.

5. The vehicle safety system of claim 1, further comprising a data acquisition unit, wherein the vehicle path data is obtained from a source external the vehicle via the data acquisition unit.

6. The vehicle safety system of claim 5, wherein the vehicle path data is GPS data and/or map data.

7. The vehicle safety system of claim 1, wherein the controlling component includes a roadway curve determination means for determining the curve in the roadway based on signals generated by one or more of the plurality of sensors.

8. The vehicle safety system 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.

9. The vehicle safety system of claim 4, wherein the at least one operator input device is selected from a group consisting of a steering wheel, an accelerator pedal, and a brake pedal.

10. The vehicle safety system of claim 1, wherein the vehicle path data is obtained from one or more sensors of the plurality of sensors.

11. The vehicle safety system of claim 1, wherein the selected vehicle operation is selected from a group consisting of steering control, braking control, and throttle control.

12. A method for mitigating a hazardous condition, comprising the steps of:

obtaining vehicle center of gravity data and one of vehicle path data and vehicle location data;

processing said data to determine a potential hazardous condition;

notifying the vehicle operator of said potential hazardous condition;

if no action is taken by the vehicle operator to mitigate the hazardous condition;

employing safety measures in an attempt to mitigate the hazardous condition.

13. The method of claim 12, wherein the vehicle location data is obtained from a GPS receiving unit.

14. The method of claim 12, wherein the vehicle path data is generated by a plurality of sensors located on the vehicle.

15. The method of claim 12, wherein the safety measures are passive countermeasures.

16. The method of claim 15, wherein the passive countermeasures are selected from a group consisting of air bag deployment and seat belt tensioning.

17. The method of claim 12, wherein the safety measures are active countermeasures.

18. The method of claim 17, wherein the active countermeasures are selected from a group consisting of steering control, braking control, and throttle control.
