Intelligent control method and device for low-speed alarm sound of automobile

Abstract

The invention provides an intelligent control method and device for low-speed alarm sound of an automobile, and belongs to the technical field of automobiles. The invention solves the problem that an existing low-speed alarm sound cannot meet the driving experience of a user. The intelligent control method for the low-speed alarm sound of the automobile comprises the following steps: when the method judges that the current position of the automobile is an interest point area and judges that the current interest point area is a crowded place, judging whether a first low-speed alarm condition is met or not according to the current driving speed of the automobile; if the method judges that the current position is a non-interest point area or the interest point area is a non-crowded place, judging whether a second low-speed alarm condition is met or not according to the current driving speed of the vehicle and information of pedestrians and non-motor vehicles around the vehicle; when a second low-speed alarm condition is met, turning on a low-speed alarm sound system and sending out sound for reminding; and if not, turning off the low-speed alarm sound system. According to the invention, the low-speed alarm sound can be automatically turned on and off, and the driving somatosensory and safety of a user are improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an intelligent control method and a control device for an automobile low-speed alarm sound. Background technique [0002] Compared with traditional cars, electric vehicles have been vigorously promoted due to their advantages such as no exhaust gas and low noise. But on the other hand, the external noise of electric vehicles (pure electric vehicles, hybrid electric vehicles, fuel cell vehicles, etc.) when driving at low speed in pure electric mode is significantly lower than that of traditional internal combustion engine vehicles, which makes other road use Ordinary people, especially blind and visually impaired people are not easy to perceive the approaching of vehicles, which can easily lead to traffic accidents. For this problem, the current solution is to make electric vehicles sound when running to remind the blind, hearing impaired and pedestrians to pay attention to saf...

Problems solved by technology

Although this solution can determine the sound pressure level of the prompt sound from the vehicle based on the sound pressure level of the external environment sound, and realize the sound reminder that is actively adjusted based on the change of the environmental noise, thereby improving the effect of the sound reminder when the environment is relatively noisy, but in the environment Avoid disturbing people when it is relatively quiet, but this solution is mainly based on the change of environmental noise to adjust the size of the sound reminder. Even if there are no pedestrians on the road, the sound reminder will still be issued, which cannot provide a quiet environment for the vehicle, and still has the problem of affecting the user's driving experience.
