Problems solved by technology

However, failure to fully test the ADAS system may reduce the effectiveness of the ADAS system when operating under many (e.g., unpredictable) conditions to which the ADAS is exposed to an infinite combination of driving situations, weather conditions, road conditions and surrounding objects and other changes in the environment

Embodiment Construction

[0020] Cars are increasingly using advanced driver assistance systems (ADAS systems) to support drivers and automate driving tasks. ADAS systems typically include sensors such as radar sensors, lidar sensors, and machine vision cameras. The sensors may be used to identify the road and / or lane ahead, as well as objects such as other cars or pedestrians around the vehicle, such as cars or pedestrians in the path of the host vehicle. These advanced driver assistance systems can warn drivers who are leaving their lane or about to collide with a vehicle in front. More recently, ADAS systems can also assume control of the vehicle, for example, by applying the brakes to avoid or mitigate an impending collision or applying torque to the steering system to prevent the host vehicle from drifting out of its lane.

[0021] However, ADAS systems can be prone to sensor failures and inconsistencies. For example, machine vision cameras may sometimes see "ghosts," or otherwise identify objec...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 245,714, filed October 23, 2015, entitled "System and Method for Advanced Driver Assistance Analysis," the entire contents of which are hereby Incorporated by reference. technical field [0003] The present disclosure relates to systems and methods for identifying unexpected events in a motor vehicle, and more particularly to systems and methods for monitoring the effectiveness of driver assistance systems. [0004] technical background [0005] Vehicles are increasingly equipped with advanced driver assistance (ADAS) systems. Driver assistance systems assist the driver in controlling the vehicle, identifying other vehicles and driving hazards, and managing multiple vehicle systems simultaneously. Driver assistance systems can affect the driver's experience by reducing the burden of operating the vehicle and by providing detailed information about...
