Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing automatic driving passive control right exchange prompt method is only applicable to the situation where the driver's attention is relatively concentrated and cannot guide the driver to focus back on the driving monitoring task, and proposes an automatic Audible reminder method for passive control switching under driving

specific Embodiment approach 1

[0020] Specific implementation mode 1: In this implementation mode, an auditory prompt design method for switching passive control rights under automatic driving The specific process is as follows:

[0021] Step 1. Divide passive control right switching scenarios into three types;

[0022] Type 1 is general early warning, which refers to the scenario where the system prompts the driver to take over the vehicle before the self-driving vehicle is about to enter a road section that is known to be unsuitable for automatic driving or beyond the functional scope of the automatic driving system, that is, a planned passive control switch , if the driver is unable or unwilling to take over the control, the risk mitigation strategy will be automatically adopted; the risk mitigation strategy is 2-5m / s 2 In the case of deceleration and automatic deceleration, stop when there is still 5-20m away from the danger distance; the road sections known to be unsuitable for automatic driving or bey...

Abstract

The invention discloses a passive control right switching auditory prompt design method under automatic driving, and relates to an auditory prompt design method in the field of automatic driving. Theinvention aims to solve the problems that the requirement of an existing prompting method for the attention of a driver is high and the driver cannot be guided to distract the attention to a driving monitoring task. Firstly, passive control right scenes are classified, auditory prompt tones are designed according to scene types and human ear auditory characteristics, then an auditory prompt tone experiment is carried out through a driving simulator to obtain psychological indexes and action indexes of a driver, and finally a unified scoring standard is established to determine the auditory prompt tones suitable for various scenes. According to the passive control right switching auditory prompt design, prompt tones with different sound frequencies are designed for planned control right switching and non-planned switching initiated by the system according to human ear auditory characteristics. The method is used for passive control right switching auditory prompt design under automaticdriving.

Description

technical field [0001] The present invention relates to an auditory prompt design method in the field of automatic driving. Background technique [0002] With the rapid development of emerging technologies such as artificial intelligence, the Internet of Things, and mobile Internet, autonomous vehicles, which are the main force of future automotive development, have gradually become the focus of the transportation industry. Self-driving cars at level L3 and above can already continuously perform all dynamic driving tasks within their design operating range, without the need for the driver to constantly monitor the vehicle's operating conditions. For driving safety, when it is necessary to switch control, the car will issue a takeover request. The scheme of reasonably prompting the driver to take over is of great significance to driving safety. [0003] According to different ways of switching control rights, it can be divided into active control right switching and passive...
