A Set of Basic Driving Manouvers to be Supported by CV

The multi-faceted potential contributions of CV to a DSS can be best discussed by first collecting basic driving manouvers which a driver has to perform in order to guide a vehicle safely through road traffic. A set of generic driving manouvers will be defined for this purpose. Generic in this context means that parameters of the following nine manouvers have to be determined on the one hand by the current subgoal which should be achieved, and on the other hand by the currently prevailing boundary conditions, in particular by the current traffic situation around the DSS vehicle:

  1. Accelerate;
  2. Follow;
  3. Approach;
  4. Pass;
  5. Cross_an_intersection;
  6. Change_lane;
  7. Turn;
  8. Reverse_driving_direction;
  9. Park_vehicle.
The generic manouver Accelerate can be specialized into the manouver `start_driving', into an acceleration or deceleration and into a stopping manouver. Approach, for example, comprises both the approach of a location on the road, of a stationary object next to the road, or of an obstacle within the lane on which the DSS-vehicle currently drives: the exact specification of what has to be approached will be provided by a suitable parameter. Similarly, the generic manouver Pass will accept the specification of a location, a stationary object on or in the vicinity of the lane currently occupied by the DSS-vehicle, or another moving vehicle. In the latter case, Pass will be equivalent to a manouver `overtake'. As another example, the generic manouver Park_vehicle can be specialized either to enter the vehicle into a parking slot or to exit a parking slot. A platooning manouver can be realized by a suitably specified form of Follow, and so on. The execution of a driving manouver implies the exertion of both lateral as well as longitudinal control. Both types of control require sensorical input about the actually prevailing relations between the vehicle and its environment. To provide such input constitutes the principal contribution of CV to a DSS. More specifically, the following pieces of information have to be obtained by CV:
