Problems solved by technology

However, this traditional power amplifier and speaker configuration cannot meet the increasingly rich individual needs of the occupants in the car.
Ordinary ultrasonic directional sounding devices cannot adjust the sounding direction and position, and the difference in the height and sitting posture of the occupants in the car makes the sound effect of this precise direction different.

Abstract

The invention belongs to the technical field of automatic driving, and particularly relates to a directional sound production system and method, the system comprises a passenger head position recognition device and a directional sound production device, the passenger head position recognition device is used for positioning the passenger head in real time and sending position information; and the directional sound production device is used for producing sound to the head of the passenger according to the position information. The head position of the passenger in the vehicle is collected in real time and modeled, learned and analyzed, the head position of the passenger in the vehicle is positioned through the ASM algorithm, positioning data is sent to the directional sound production device, sound is always directionally sent according to the head position of the passenger in the vehicle, and the best sound sense experience is provided all the time.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a directional sounding system and method. Background technique [0002] At present, the automotive industry is developing towards autonomous driving. The driver's main tasks and attention are gradually liberated from the control of the vehicle. On this basis, the driver and the occupants have different personalities for information acquisition and entertainment. demand. Video and audio are integral parts of it. At present, ordinary car power amplifiers and speaker systems can only play the same audio in the entire cab, and all members of the car are in the same sound field, which can be adjusted through the front touch screen so that the main sound field is concentrated on the position of the driver and each occupant in the car. But this traditional power amplifier and speaker configuration cannot meet the increasingly rich individual needs of the occupants in the car...
