Abstract

A vehicle operation control device utilizes a plurality of sensors and receivers to develop an absolute rule set and a relative rule set that take into account the capabilities of the vehicle, the condition of the roadway, the preferences of the operator and the operation of surrounding vehicles. The vehicle operation control device uses information from both an absolute rule set and a relative rule set to define a set of operating principles that can be varied as necessary to improve safely and the comfort of the operator and/or the passengers within the controlled vehicle. The absolute rule set is based primarily on road information and operating regulations with which an operator should normally comply during operation of any vehicle. The relative rule set is based primarily on the relative positioning and movement of other vehicles in the vicinity of the controlled vehicle or farther along the intended path.

Claims

1. A vehicle operation control system comprising;

a road information acquisition device;

a controlled vehicle information acquisition device;

an other vehicle information acquisition device;

an absolute rule setting device;

a relative rule setting device,

a vehicle operation control device for controlling a controlled vehicle in response to operating principles developed from information received from both the absolute rule setting device and the relative rule setting device.

2. The vehicle operation control system according to claim 1, wherein:

the vehicle operation control device modifies the operating principles in response to information received from the relative rule setting device to increase separation distance between the controlled vehicle and another vehicle.

3. The vehicle operation control system according to claim 2, wherein:

the vehicle operation control device modifies the operating principles to direct the controlled vehicle from a centered position to an offset position within a selected lane to increase the separation distance between the controlled vehicle and another vehicle.

4. The vehicle operation control system according to claim 1, wherein:

the vehicle operation control means modifies the operating principles in response to information received from the absolute rule setting device to accommodate an operator preference.

5. The vehicle operation control system according to claim 4, wherein:

the vehicle operation control means modifies the operating principles to increase the stopping distance and limit a stopping deceleration force.

6. The vehicle operation control system according to claim 4, wherein:

the vehicle operation control means modifies the operating principles to reduce speed through curved portions of a roadway and thereby limit a lateral acceleration force.

7. The vehicle operation control system according to claim 1, wherein:

a road information acquisition device develops a road data set corresponding to an anticipated route for the controlled vehicle.

8. The vehicle operation control system according to claim 7, wherein the road information acquisition device develops said road information relating to at least one parameter selected from a group consisting of road condition, road width, traffic control signals, road signs, traffic signs, crossing roadways, merging roadways, diverging roadways, curved roadway portions, and road slope.

9. The vehicle operation control system according to claim 1, wherein:

an operational characteristics setting device develops a set of operator specific operational characteristics during an operator'"'"'s operation of the controlled vehicle.

10. The vehicle operation control system according to claim 1, wherein:

a vehicle condition setting device develops a set of vehicle specific operational characteristics during operation of the controlled vehicle.

11. The vehicle operation control system according to claim 1, wherein:

an operational preferences setting device develops a set of operator specific operational characteristics based on an operator'"'"'s input.

12. The vehicle operation control system according to claim 1, wherein:

a road information acquisition device develops a road data set corresponding to an anticipated route for the controlled vehicle;

an operational characteristics setting device develops a set of operator specific operational characteristics during an operator'"'"'s operation of the controlled vehicle;

a vehicle condition setting device develops a set of vehicle specific operational characteristics during operation of the controlled vehicle; and

an operational preferences setting device develops a set of operator specific operational characteristics based on an operator'"'"'s input.

13. The vehicle operation control system according to claim 12, wherein:

the absolute rule setting device develops an absolute rule set from one or more data sources selected from a group consisting of a road data set corresponding to an anticipated route for the controlled vehicle, a set of operator specific operational characteristics, a set of vehicle specific operational characteristics; and

a set of operator specific operational characteristics.

14. The vehicle operation control system according to claim 1, wherein:

the vehicle operation control device provides an adaptive cruise control function and a lane maintenance function.

15. The vehicle operation control system according to claim 14, wherein:

the adaptive cruise control function maintains a minimum separation distance between the controlled vehicle and a leading vehicle.

16. The vehicle operation control system according to claim 15, wherein:

the minimum separation distance is determined in light of at least one factor selected from a group consisting of current speed of the controlled vehicle, brake system capability, road surface condition and road surface incline.

17. The vehicle operation control system according to claim 1, wherein:

the vehicle operation control device is configured for selective engagement and controlled manipulation of at least two vehicular controls selected from a group consisting of a throttle, a steering assembly, a brake assembly and a transmission, thereby operating the controlled vehicle in a manner consistent with the operating principles.

18. The vehicle operation control system according to claim 1, wherein:

the operating principles are periodically revised in response to the information received from the relative rule setting device reflecting changes in the other vehicle information.

19. The vehicle operation control system according to claim 18, wherein:

the operating principles remain within operational bounds defined by the absolute rule setting device.

20. The vehicle operation control system according to claim 1, further comprising:

an alarm for alerting the operator to potential violations of the operating principles.

21. The vehicle operation control system according to claim 1, further comprising:

a failsafe rule set for reducing risk associated with unavoidable violations of the operating principles.

22. The vehicle operation control system according to claim 12, wherein:
