Embodiment 1

[0059] like Figure 4 As shown, the automobile low-speed alarm sound intelligent control device includes a low-speed alarm sound system 4, a positioning system 1, a multimedia unit 6, a chassis control unit 7, a sensor device 2 and a vehicle control unit 5, and the low-speed alarm sound system 4 is connected with the vehicle The output end of the control unit 5 is connected, the positioning system 1 is connected with the multimedia unit 6, the multimedia unit 6, the chassis control unit 7 and the sensing device 2 are all connected with the input end of the vehicle control unit 5, wherein the sensing device 2 includes radar and Camera, through radar and camera to obtain information of pedestrians and non-motorized vehicles around the vehicle.

[0060] The automobile low-speed alarm sound intelligent control device realizes the automobile low-speed alarm sound intelligent control method by arranging various functional components respectively correspondingly. The working princip...

Embodiment 2

[0065] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that, as Figure 5As shown, the vehicle low-speed alarm sound intelligent control device also includes a body control unit 8 for detecting whether the current driving mode of the vehicle is in the pure electric mode, and a body control unit 8 for obtaining the background noise value of the surrounding environment of the vehicle in real time and sending it to the body control unit 8. Noise sensor 3, noise sensor 3 is connected with the input terminal of vehicle body control unit 8, the output terminal of vehicle body control unit 8 is connected with the input terminal of vehicle control unit 5; The current driving speed is used to jointly judge whether the low-speed warning condition 1 is satisfied, and it is used to jointly judge whether the low-speed warning condition 2 is satisfied according to the current driving mode of the vehicle, the current...

Embodiment 3

[0073] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that, as Image 6 Shown, this automobile low-speed alarm sound intelligent control device also includes the button switch 9 that is arranged on the multimedia unit 6, the button switch 9 is used to start or close this automobile low-speed alarm sound intelligent control function, the multimedia unit 6 is connected with the button switch 9, It is used to monitor the switch state signal of the button switch 9 and send it to the vehicle control unit 5; When the speed is lower than the target speed threshold, it is determined that the low-speed alarm condition one is satisfied and used when the button switch 9 is on, the current driving mode of the vehicle is pure electric mode, the current driving speed of the vehicle is lower than the target speed threshold, and there are pedestrians and vehicles around the vehicle. / or when non-motor vehicle is jud...

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...
