Abstract

The embodiment of the invention provides an early alarming method and a vehicle. The early warning method is applied to vehicles with vehicle control equipment and comprises, when a movable obstacle in front of a moving vehicle is detected, acquiring the distance between the vehicle and the movable obstacle; according to the distance and the attenuation law of sound to distance, determining the early alarming volume; generating early alarming signals according to the early alarming volume; outputting the early alarming signals. The early alarming method can precisely control the volume.

Description

technical field [0001] This application relates to the field of electricity, in particular to an early warning method and a vehicle. Background technique [0002] With the continuous development of electronic technology, vehicles have become an indispensable means of transportation in people's daily life. The vehicle is equipped with speakers, such as horns, etc. When the driver finds a moving obstacle in front of the vehicle, he can press the speaker to remind the moving obstacle or the driver on the moving obstacle to avoid the vehicle. However, since the driver has no control over how hard to press the speaker, it is impossible to precisely control the volume. Contents of the invention [0003] Embodiments of the present application provide an early warning method and a vehicle for precise volume control. [0004] The first aspect provides an early warning method, the method is applied to a vehicle equipped with a vehicle control device, including: [0005] When dete...
