Embodiment 1

[0085] (1) After the system self-inspection is started, the camera and microwave radar are started at the same time; (2) The camera captures the video image of the road ahead of the vehicle in real time; (3) The controller sets the target detection and classification algorithm based on deep learning to analyze the video image For vehicle and pedestrian detection and classification, since the camera is fixedly installed in front of the front bumper of the vehicle, the actual orientation of the image position where the target is located can be calibrated in advance, and based on the calibration results, the specific orientation and motion situation of the detected target relative to the vehicle can be analyzed ; (4) The microwave radar selectively perceives the distance and speed of the measured target relative to the vehicle according to the obtained target orientation; (5) When the driver triggers the whistle switch, the controller is based on the degree of danger of the measure...

Abstract

The invention discloses an automobile automatic control honking device, method and system. The automobile automatic control honking device includes a video sensor, a microwave radar probe, a speed sensor and a controller, and the video sensor is used for detecting image information of a traffic scene in front of a vehicle; the microwave radar probe is used for obtaining distance information of objects around the vehicle; the speed sensor is used for perceiving speed information of the vehicle; the video sensor and the microwave radar probe are located on a bumper in front of the vehicle; and the controller is connected with the video sensor, the microwave radar probe and the speed sensor, and used for controlling the honking volume by fusing the image information of the traffic scene, thedistance information and the speed information. According to the automobile automatic control honking device, method and system, the noise pollution can be reduced, and safe driving of the vehicle isimproved.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a device and method for automatic control and whistle of automobiles. Background technique [0002] During the actual driving process of the vehicle, the driver uses the car horn to warn pedestrians and attract the attention of other vehicles to ensure traffic safety, and it is also used to remind and transmit signals. At present, the horns used in vehicles are divided into air horns and electric horns according to the sound power. Among them, the electric horn has the advantages of convenient energy, simple structure, small size, small quality, low noise, easy maintenance, loud sound and pleasant sound quality, etc. Advantages, it has been widely used in general vehicles. [0003] The car electric horn is composed of iron core, magnetic coil, contact, armature, diaphragm, etc. Its basic working principle is to use electromagnetic attraction to vibrate the metal...
