Problems solved by technology

[0003] In order to achieve the warning function of the whistle, the decibels generated by the traditional vehicle horn system are high when the whistle is issued, and the volume is generally fixed, and the volume of the horn cannot be adjusted according to the environment of the car, let alone Adaptive honking to pedestrians or animals in front will not only easily cause noise pollution to the environment, but sudden high-pitched whistle will also easily frighten pedestrians or animals, cause conflicts, and cause unnecessary traffic accidents

Embodiment 1

[0039] The embodiment discloses a vehicle whistle system, which includes a vehicle control system, a distance sensor, an infrared sensor, an image recognition system and a loudspeaker connected in communication with the vehicle control system. The distance sensor and infrared sensor are installed at the front of the vehicle, which is close to the installation position of the car radar, and the front glass of the car is made of opaque heat-insulating glass to prevent people in the car from interfering with the detection of the infrared sensor. Described distance sensor can select radar sensor, selects infrared ranging sensor or laser ranging sensor, and present embodiment selects laser ranging sensor for use, and this laser ranging sensor model is DX500, purchased from sick company, the horizontal angle of laser ranging sensor is 60°, the vertical angle is 4°, and the detection distance is 28m. The infrared sensor model is HW1004+8003-3, purchased from Shenzhen Haiwang Sensor C...

Embodiment 2

[0043] This embodiment provides a vehicle intelligent whistle method, figure 1 It shows the implementation flow chart of the vehicle whistle method provided by the embodiment of the present invention, figure 2 A schematic diagram of the judging process of the vehicle intelligent whistle method is shown. The method is based on the vehicle intelligent whistle system in embodiment 1, and the method comprises the following steps:

[0044] 101. Receive a speaker start instruction.

[0045] 102. Obtain the life activity of the obstacle, if the obstacle has no life activity, output a signal to the speaker, and if the obstacle has life activity, extract the activity feature of the obstacle.

[0046] The life activity of the obstacle is detected by an infrared sensor, and the effective detection angle of the infrared sensor is ≤120°.

[0047]Specifically, to extract the active features of obstacles, it is first necessary to obtain images including obstacles through the camera, and ...

Embodiment 3

[0056] Such as figure 2 As shown, the present embodiment is similar to Embodiment 2, and preferably, a distance detection step is also included between S101 and S102:

[0057] Obtain the distance between the obstacle and the vehicle. If the distance is greater than or equal to the distance threshold, output a signal to the speaker. If the distance is less than the distance threshold, perform the step of obtaining the life activity of the obstacle.

[0058] The distance between the obstacle and the vehicle is detected by an infrared ranging sensor.

Abstract

The invention relates to a vehicle intelligent whistling method. The method comprises the following steps that a loudspeaker starting instruction is received; the life activity of an obstacle is acquired, if the obstacle has no life activity, a first signal is output to a loudspeaker, and if the obstacle has the life activity, the activity characteristic of the obstacle is extracted; and a corresponding signal is output to the loudspeaker according to the activity characteristic. Compared with the prior art, the intelligent whistling method can correspondingly adjust the volume of the loudspeaker in the whistling process according to the distance between the obstacle and a vehicle, whether the obstacle has the life activity or not and the activity characteristic of the obstacle, so that the problem of environmental noise pollution caused by the fact that unnecessary high-decibel whistling sounds are generated is solved, meanwhile, sudden scares caused by the whistling sounds to children and animals can be avoided, and the occurrence probability of accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle whistle, in particular to a method for intelligent vehicle whistle. Background technique [0002] With the continuous development of science and technology, people's quality of life has been continuously improved, and the sales of vehicles have also increased. Vehicles have not only become an important means of transportation, but also a means of transportation for people to go to work, bringing great convenience to people's lives. However, with the rapid increase in the number of vehicles on the road, the pollution of traffic noise to the environment has become increasingly prominent, which has gradually attracted people's attention. In fact, the sound of car horns has become the most important source of urban noise pollution. Whether it is on the continuous road, or in offices, schools and other places, the impact of car noise can be felt. Car noise will not only increase the fatigue of driver...
