Automatic alarm-volume regulating method in automotive advanced driving assistance

Abstract

The invention discloses an automatic alarm volume regulating method in automotive advanced driving assistance. The automatic alarm volume regulating method comprises the following steps that (1) minimum alarm volume and maximum alarm volume are preset in an alarm system; (2) environment volume around a vehicle is acquired in real time through a volume acquiring device; (3) the alarm system automatically regulates the current alarm volume according to the acquired environment volume, and the regulated alarm volume is between the minimum alarm volume and the maximum alarm volume; (4) when an alarm behavior is triggered, the alarm system automatically selects the alarm volume which is regulated most recently for alarm. Through the adoption of the automatic alarm volume regulating method disclosed by the invention, the problem that alarm volume is complicated to regulate in a voice alarm manner of an ADAS is solved, and the practical value of the ADAS is effectively improved; the automatic alarm volume regulating method disclosed by the invention has an extensive market application prospect.

Description

technical field [0001] The invention relates to an ADAS system for vehicles, in particular to a method for automatically adjusting alarm volume in advanced driving assistance for vehicles. Background technique [0002] With the popularity of cars and the increasing level of technology, advanced driver assistance systems (ADAS) have been popularized in many high-end cars. In the actual ADAS system, it generally has functions such as collision warning and car following warning. Collision warning is the warning information issued in advance when the system judges that a collision (person or vehicle) is about to occur. In this situation, the driver must react immediately to avoid a possible collision. Follow-up warning is an early warning message sent when the distance between the vehicle and the vehicle ahead in the same lane is less than a certain set value (usually converted into time based on speed). Relatively speaking, follow-up warning is less urgent and dangerous than...

Problems solved by technology

However, it is very troublesome to manually adjust the alarm volume by the driver, and the driver needs to concentrate on driving, and it is difficult to allocate energy to manually adjust the alarm volume frequently

This makes it difficult to use the interface provided by the ADAS system, which appears redundant and wasteful. At the same time, it also causes the alarm disadvantages of the voice alarm method of the ADAS system, and sometimes even causes serious safety accidents.
