Embodiment 1

[0026] A sounding system outside a vehicle, comprising a controller, a signal collecting device, and a sounding device, wherein the controller is connected to the signal collecting device, and at least two sounding devices are connected to the controller, and the two sounding devices are respectively used to be arranged in front of the vehicle, back, left and right directions. According to the obstacle position information of the signal acquisition device, the controller controls the sound emitting device closest to the obstacle to sound a reminder.

[0027] According to the obstacle information of the signal collection device, the controller controls the corresponding sounding device to make a sound. The volume range of the sound is 68-72dB, reminding pedestrians and small animals within the calibration range of the collected information to avoid in time, ensuring the safety of pedestrians at the same time Reduce noise pollution and protect the environment.

Embodiment 2

[0029] Such as figure 1 Shown is a vehicle 5 comprising an external sounding system, which includes a controller 1, an information collection device 2, a sounding device 3, a vehicle speed sensor 6, and a vehicle power supply 4, wherein the information collection device 2, the sounding device 3, the vehicle speed The sensor 6 and the vehicle power supply 4 are respectively connected to the controller 1 . The information collection device 2 includes four cameras and / or four radars, and one camera and / or radar is arranged in each direction around the vehicle. The sounding device 3 includes 4 loudspeakers, which are respectively arranged around the vehicle; the vehicle power supply 4 provides power for the external sounding device. When the controller 1 receives the vehicle speed sent by the vehicle speed sensor 6 and is within the set range, it controls the information collection device 2 to identify obstacle information within the calibration range, and realizes automatic open...

Abstract

The invention relates to an exterior sound generating system and a passenger car. Two sound generating devices are arranged in two of the four directions, namely the front, back, left and right directions, of the vehicle, signal collecting devices are arranged in the vehicle directions of the sound generating devices correspondingly, and when controllers receive the obstacle information of the signal collecting devices, the controllers control the corresponding sound generating devices to generate sound at a low volume, to remind nearby pedestrians and small animals of avoiding the vehicle intime, and noise pollution is reduced and the environment is protected.

Description

technical field [0001] The invention belongs to the field of automobile control, and in particular relates to an external sounding system and a passenger car. Background technique [0002] With the rapid development of pure electric vehicles, the potential safety hazards they may bring have attracted much attention. In order to ensure the safety of the visually impaired, pure electric vehicles should emit warning sounds when driving at low speeds to give appropriate reminders to people outside the vehicle, so as to avoid collision accidents. At present, the existing radar detection technology mainly helps the driver to calculate the actual distance between the car body and the obstacle when the car is parked or reversed, and prompts the driver. For pedestrians, the existing radar detection technology does not provide sound warnings to pedestrians when vehicles are approaching, so that collision accidents cannot be effectively avoided. [0003] The Chinese patent with the p...
