Method of Operating a Driver Assistance System of a Motor Vehicle

摘要

A driver assistance system includes a sensor that detects objects and/or characteristics of objects in the surroundings of a motor vehicle, and an object recognition unit that evaluates data from the sensor to produce object information, and determines a confidence value indicating the probability of accuracy thereof. If the confidence value is greater than a minimum threshold but less than a predefined threshold, then the system displays the object information to the driver, who confirms or rejects it, e.g. by actuating or not actuating an operating element. Upon confirmation by the driver, the system begins or continues to perform a driver assistance function based on the object information. Upon rejection by the driver, the system does not perform or discontinues the driver assistance function based on the object information. If the confidence value exceeds the predefined threshold, then the system autonomously performs the driver assistance function.

1. A method of operating a driver assistance system of a motor vehicle, said system having at least one surroundings sensor, a processing circuit, an output device connected to said processing circuit and configured to produce an output perceivable by the driver of said motor vehicle, and an input device connected to said processing circuit and configured to register an input from a driver of said motor vehicle, wherein said method comprises the steps:
a) using said at least one surroundings sensor, detecting objects in a surrounding environment of said motor vehicle and producing sensor signals indicative of said detected objects; b) in said processing circuit, evaluating said sensor signals and producing a respective object information including an identification and/or an object characteristic of at least one respective target object among said detected objects; c) in said processing circuit, determining a respective confidence value representing a probability of accuracy for said identification and/or said object characteristic of said at least one target object respectively; d) in said processing circuit, comparing said respective confidence value to a prescribed threshold; e) if said respective confidence value in said step d) falls below said prescribed threshold then producing as said output from said output device a driver information comprising said respective object information; and f) after said step e), using said processing circuit, checking an input status of said input device, and if said input status indicates confirmation of said respective object information by the driver then performing or continuing to perform a driver assistance function of said driver assistance system based on said respective object information.
