Method and device for capturing information of a driver assistance system
A method and a device for capturing information of a parking assistance system of a vehicle. The method includes storing of information which is used during operation of the parking assistance system in a memory; provision of a parking assistance function by the parking assistance system; detecting whether a condition, of one or more predefined conditions, is fulfilled, and an at least partial provision of the information stored in the memory in response to the condition being fulfilled.
1 . A method for capturing information of a parking assistance system of a vehicle, comprising the following steps:
continuously storing, in a ring memory of the vehicle: (a) input signals that includes sensor signals of a sensor system of the vehicle, (b) internal signals generated by the parking assistance system for performing parking assistance, and (c) output signals of the parking assistance system that automatedly control drive operations of the vehicle during provision of the parking assistance, wherein the ring memory is configured to continuously overwrite previously stored signals during operation of the parking assistance system until one of a plurality of predefined conditions is satisfied;
detecting whether one of the plurality of predefined conditions is fulfilled, the plurality of predefined conditions comprising at least two different conditions corresponding to different respective operating scenarios of the parking assistance system; and
in response to detecting that one of the plurality of predefined conditions is fulfilled:
selecting one of a plurality of predefined subsets of the stored signals depending on which of the plurality of predefined conditions has been detected, wherein the subsets differ from one another with respect to predetermined temporal intervals of the stored signals relative to a time of fulfillment of the detected predefined condition and with respect to signal types of the stored signals;
extracting from the ring memory the selected one of a plurality of predefined subsets of the stored signals; and
storing and/or transmitting the extracted subset of the stored signals.
2 . The method according to claim 1 , wherein the plurality of predefined conditions include a condition that is fulfilled when a parking assistance function provided by the parking assistance system is successfully completed.
3 . The method according to claim 1 , wherein the plurality of predefined conditions include a condition that is fulfilled when a parking assistance function executed by the parking assistance system is prematurely terminated by a user prior to completion of the parking assistance function.
4 . The method according to claim 1 , wherein the one or more predefined conditions include a condition that is fulfilled when the vehicle has been manually parked, although an automatic parking maneuver is recognized as having been available.
5 . The method according to claim 1 , wherein the one or more predefined conditions include a condition that is fulfilled when a parking assistance function provided by the parking assistance system intervenes in a driving event to perform, without previous driver action, an emergency braking process for avoiding a collision.
6 . The method according to claim 1 , wherein the one or more predefined conditions include a condition that is fulfilled when an error occurs in a provision of a parking assistance function, the error occurring by a software sequence of the parking assistance system leads.
7 . The method according to claim 1 , wherein method includes the transmitting of the extracted subset of the stored signals, and the transmitting takes place via a radio interface.
8 . The method according to claim 1 , further comprising:
capturing an image which shows an environment of the vehicle during provision of a parking assistance function or when the predefined condition is present, and
providing the image together with the extracted subset in response to the predefined condition being fulfilled.
9 . The method according to claim 1 , wherein the plurality of predefined conditions are configured via a radio interface.
10 . The method according to claim 1 , wherein the plurality of predefined conditions include a condition that is fulfilled when a parking assistance function is aborted before completion of the parking assistance function.
11 . The method according to claim 1 , wherein the plurality of predefined conditions include a condition that is fulfilled when a value of an evaluation by a user, which evaluates a parking assistance function performed by the parking assistance system, is within a predefined evaluation value range.
12 . The method according to claim 1 , wherein the one or more predefined conditions include a condition that is fulfilled when the vehicle has been manually parked and that no automatic parking guidance by the parking assistance system was possible is recognized by the parking assistance system.
13 . The method according to claim 1 , wherein the one or more predefined conditions include a condition that is fulfilled when, in a provision of a parking assistance function, conflicting information is detected by sensors of the parking assistance system.
14 . The method according to claim 1 , wherein the one or more predefined conditions include a condition that is fulfilled when, in a provision of a parking assistance function, invalid information is detected by a sensor of the parking assistance system.
15 . A device for capturing information of a parking assistance system of a vehicle, comprising:
a control unit comprising at least one processor; and
a ring memory;
wherein the control unit is configured to:
continuously store, in the ring memory of the vehicle: (a) input signals that includes sensor signals of a sensor system of the vehicle, (b) internal signals generated by the parking assistance system for performing parking assistance, and (c) output signals of the parking assistance system; that automatedly control drive operations of the vehicle during provision of the parking assistance, wherein the ring memory is configured to continuously overwrite previously stored signals during operation of the parking assistance system until one of a plurality of predefined conditions is satisfied;
detect whether one of the plurality of predefined conditions is fulfilled, the plurality of predefined conditions comprising at least two different conditions corresponding to different respective operating scenarios of the parking assistance system; and
in response to detecting that one of the plurality of predefined conditions is fulfilled:
select one of a plurality of predefined subsets of the stored signals depending on which of the plurality of predefined conditions has been detected, wherein the subsets differ from one another with respect to predetermined temporal intervals of the stored signals relative to a time of fulfillment of the detected predefined condition and with respect to signal types of the stored signals;
extract from the ring memory the selected one of a plurality of predefined subsets of the stored signals; and
store and/or transmit the extracted subset of the stored signals.
