Method for providing information on the reliability of a parametric estimation of a parameter for the operation of a vehicle
The disclosure relates to a method for providing information on the reliability of a parametric estimation of a parameter for the operation of a vehicle, comprising at least the following steps: a) identifying an integrity range for the parametric estimation, the integrity range describing the range in which an estimated parameter is located with a minimum probability, b) identifying a validity indicator which describes the validity of the integrity range identified in step a), c) providing the integrity range identified in step a) and the validity indicator identified in step b).
1 . A method for providing information on a reliability of a parametric estimation of a parameter for an operation of a vehicle, comprising:
identifying a protection level for the parametric estimation of the parameter, the identified protection level describing a range in which the parametric estimation of the parameter is located with a minimum probability;
calculating, based on at least one condition of the vehicle, a validity indicator which describes a validity of the identified protection level, the identified validity indicator being a value from a predetermined quantity of values, the predetermined quantity of values including at least three different values;
providing the identified protection level and the identified validity indicator; and
operating the vehicle depending on the parametric estimation of the parameter, the identified protection level, and the identified validity indicator,
wherein the at least one condition the vehicle includes at least one of (i) a longitudinal or lateral acceleration of the vehicle being outside a defined limit, (ii) a failure of a system or sensor of the vehicle, (iii) a weather condition, and (iv) sensor shading of a sensor of the vehicle.
2 . The method according to claim 1 , wherein at least one of:
identifying the protection level comprises identifying the protection level based on sensor data of at least one sensor of the vehicle; and
identifying the validity indicator comprises identifying the validity indicator based on the sensor data of the at least one sensor of the vehicle.
3 . The method according to claim 1 , wherein the protection level is identified based on statistical confidence information on the parametric estimation.
4 . The method according to claim 1 , wherein the identified validity indicator is identified using at least one piece of environmental information on an environment of the vehicle.
5 . The method according to claim 1 , wherein the identified validity indicator is identified using at least one piece of status information on the status of the vehicle or of a component thereof.
6 . The method according to claim 1 , wherein the identified validity indicator is identified using the identified protection level.
7 . The method of claim 1 wherein a computer program is executed by a controller, to perform the method.
8 . The method of claim 7 wherein the computer program is stored on a non-transitory machine-readable storage medium.
9 . The method of claim 1 wherein a controller for the vehicle is configured to perform the method.
