A kind of intelligent control method and control device of automobile low-speed alarm sound

Abstract

The invention provides an intelligent control method and a control device for an automobile low-speed alarm sound, belonging to the technical field of automobiles. It solves the problem that the existing low-speed warning sound cannot satisfy the user's driving experience. The intelligent control method for the low-speed alarm sound of the vehicle includes the following steps: when it is judged that the current position of the vehicle is a point of interest area and the current point of interest area is judged to be a crowded place, determining whether the low-speed alarm condition is satisfied according to the current driving speed of the vehicle First, if it is judged that the current location is a non-point of interest area or a point of interest area is not a crowded place, it is judged whether the low-speed alarm condition is satisfied according to the current driving speed of the vehicle and the information of pedestrians and non-motor vehicles around the vehicle. When the conditions are met, the low-speed alarm sound system is turned on and a sound reminder is issued. When the conditions are not met, the low-speed alarm sound system is turned off. The invention can realize the automatic opening and closing of the low-speed alarm sound, and improves the user's driving feeling and safety.

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 vehicles, electric vehicles have been vigorously promoted due to their advantages of no exhaust gas and low noise. But on the other hand, when electric vehicles (pure electric vehicles, hybrid electric vehicles, fuel cell vehicles, etc.) drive at low speed in pure electric mode, the noise outside the vehicle is significantly lower than that of traditional internal combustion engine vehicles, which makes other road use People, especially blind and visually impaired people, are not easy to detect the approach of vehicles, which can easily lead to traffic accidents. For this problem, the current solution is to make the electric vehicle emit a sound when it is running to remind the blind, hearing-impaired and pedestrians to pay attenti...

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.
