US 10,427,655 B2 · Systems and methods for detecting surprising events in vehicles

Abstract

A driver assistance system is presented, including an event detector which comprises a set of rules defining a surprising event based on signals reflecting a vehicle operator input signals from an object detection sensor. An event data file generator is configured to generate an event data file according to rules comprised in the event detector, the event data file comprising a video signal received from a camera, a signal from at least one dynamic vehicle sensor, and target object information received from the object detection sensor. The event data file generator is further configured to initiate data file generation responsive to a surprising event being detected by the event generator, and wherein the contents of the data file are specified by the rules comprised in the event detector. In this way, surprising events may be collected and analyzed off-board in order to generate updates for the driver assistance system.

Dependent claims

A surprising event detection system for a vehicle having a driver assistance system that controls lateral and/or longitudinal movement of the vehicle, the surprising event detection system comprising:

an interface communicatively connected to a camera, at least one dynamic vehicle sensor, and an object detection sensor;
a processor;
and
one or more storage devices that store a set of rules defining a surprising event based on a combination of at least two input signals and that further store instructions executable by the processor to:
generate, with an event data file generator responsive to a surprising event being detected, an event data file comprising:
a video signal received from the camera;
a signal from the at least one dynamic vehicle sensor;
and
object information received from the object detection sensor,
periodically export event data to an analytic server, and
receive an update patch from an update server and apply the update patch to the surprising event detection system, wherein the update patch comprises updated rules adjusting a spectrum of surprising events to be stored and adjusting a handling of a detection of each surprising event of the spectrum of surprising events, the adjusting of the handling of the detection of each surprising event including adjusting a weight of data received from a selected sensor responding to an indication of a change in reliability of the selected sensor.

A method for detecting surprising events in a vehicle having a driver assistance system that controls lateral and/or longitudinal movement of the vehicle, the method comprising:

receiving signal data from one or more onboard vehicle sensors and one or more object identification sensors;
receiving video data from one or more video cameras;
storing the signal data and the video data in an event data buffer;
identifying a surprising event from the received signal data based on surprise event rules stored at a storage device;
deriving an event data file for the surprising event based on the surprise event rules;
uploading the event data file to a server;
receiving an update patch from the server, comprising updated surprise event rules;
and
applying the update patch to adjust a packaging of event data files, to change the surprise event rules by adjusting a spectrum of events detected, and to adjust a handling of event data files according to associated assigned priorities by adjusting a weight of data received from a selected sensor responsive to an indication of a change in reliability of the selected sensor.
