Description

Technical Field

[0001] The utility model relates to a voice prompter detection device, in particular to a steering voice prompter detection device. Background Art

[0002] With the rapid development of the automotive industry and the continuous innovation of intelligent transportation systems, vehicle safety has become a growing concern for the public. While pursuing an exceptional driving experience, ensuring driving safety has become a major challenge faced by both automakers and traffic management authorities. Especially in the field of large transport vehicles, due to their large size, drivers face limited rearview mirror visibility when turning left or right. This easily creates blind spots, increasing the risk of collisions with pedestrians traveling straight on bicycles or electric scooters, leading to serious accidents. The importance of voice steering systems, a key technology for improving driving safety, has become increasingly prominent in this context. By monitoring the vehicle's steering state in real time and combining voice technology to issue warnings, they effectively alert nearby pedestrians and non-motorized vehicles to yield, significantly reducing the risk of potential traffic accidents, especially those high-risk situations that occur when large vehicles are turning.

[0003] As users' demands for driving safety and comfort continue to increase, the performance stability and user experience of steering voice prompts have become new concerns. In emergency situations, the stability and response speed of the device are directly related to the effectiveness of accident prevention. Therefore, comprehensive and accurate testing of steering voice prompts has become particularly important.

[0004] Currently, most detection systems for steering voice prompts rely on human auditory judgment and voltage change detection methods. Although this method is intuitive, it has obvious limitations in practical applications, such as slow detection speed and low accuracy, and cannot meet the modern automotive industry's demand for efficient and accurate detection.
