Abstract

The embodiment of the invention provides a method and a device for controlling prompt tone playing, and a movable carrier. The method and the device are applied to the movable carrier. The movable carrier comprises a voice prompt device used for playing low-speed driving prompt tone. The method comprises the following steps: from multiple speed ranges, confirming the specific speed range to whichthe driving speed of the movable carrier belongs; and adjusting the low-speed driving prompt tone played by the sound prompt device according to the specific speed range. According to the technical scheme of the embodiment of the invention, the volume of the prompt tone of low-speed driving can be adjusted at least according to multiple speed ranges of low-speed driving, and the driving safety ofthe low-noise movable carrier is improved.

Description

technical field

[0001] The present application relates to the field of voice prompts of low-noise removable carriers, and in particular, relates to a method, device and removable carrier for controlling playback of prompt sounds. Background technique

[0002] The power system of some movable carriers (for example, unmanned vehicles or new energy vehicles) is a motor, and the various noises generated by these movable carriers when driving at low speeds are very small (such as motor sound and tire noise), and cannot remind passers-by The vehicle is in a driving state, causing trouble to passers-by. In addition, passersby also have the problem of hindering the smooth movement of mobile carriers when they cannot hear the sound prompts, which affects operational efficiency. Contents of the invention

[0003] The purpose of the embodiment of the present application is to provide a method, device and movable carrier for controlling the play of the prompt sound. Through the techn...
