​
Check Name

ADAS Ground Truth Objects Time To Collision Observation

​
Description

Observes the Time To Collision (TTC) between Moving Objects and the EgoVehicle. The check fires an event if the TTC conditions passed as arguments are fulfilled.

​
Parameters

  • overUnder: Specifies if the distance violation is over or under the specified value.
  • threshold: Specified value that determines the maximum or minimum TTC. The distance is specified in meter.
  • laneId: Only Moving Objects on the lane with the given laneId will be checked. If no laneId is given or the laneId is -1, only the lane of the EgoVehicle will be considered.
  • movingObjectId: GroundTruthId of the moving object. Only the distance to this Moving Object will be checked. If the value -1 is given, all Moving Objects will be checked.
  • callback: This parameter is optional. Name of the callback which is called when the check fails. Signature: void Callback( dword checkId ) or void Callback( TestCheck check )

​
Return Values

  • 0: Check could not be created and must not be referenced
  • > 0: Check was created successfully and may be referenced using the returned (handle-) value.

​
Possible Errors

  • EgoVehicleId is undefined.
  • CAPL callback does not exist.

​
Example

enum OverUnder
  {
    kUnder = 0,
    kOver = 1
  };

dword  checkId1, checkId2;
checkId1 = chkStart_ADASGroundTruthObjectsTimeToCollisionViolation (kUnder, 1.0); // TTI under 1s to EgoVehicle of any Moving Object will trigger the check
checkId2 = chkStart_ADASGroundTruthObjectsTimeToCollisionViolation (kOver, 5.0, 2, 100); // TTI over 5s from EgoVehicle to Moving Object with ID 100 on lane with ID 2 will trigger the check

TestAddCondition(checkId1);
TestAddCondition(checkId2);
// sequence of different actions and waiting conditions
TestWaitForTimeout(3000);
TestRemoveCondition(checkId1);
TestRemoveCondition(checkId2);
