Embodiment Construction
[0011] Such as figure 1 As shown, the method for detecting dangerous approaching objects in the running of a car of the present invention includes a step of installing a car radar 1 on the car, a process of using the car radar 1 to detect obstacle distances, wherein, using the car radar 1 During the process of radar 1 detecting the obstacle distance, within the range of 360 degrees parallel to the four-wheel plane of the car, the detection direction of the car radar 1 is changed at a constant speed clockwise or counterclockwise, and the detection direction of the car radar 1 is displayed on the display device 2. The display in the car uses the display device 2 or the audio device to prompt the information that the obstacle is approaching.
[0012] Further, the sensor is used to detect the current driving speed of the vehicle, and the rotational angular velocity in the detection direction of the vehicle radar 1 is increased or decreased according to the current driving speed of...

The invention discloses a method for detecting a dangerous approaching object during automobile driving. The method includes a step of installing an automobile radar on an automobile and a process ofusing the automobile radar to detect the distance of an obstacle, the detection direction of the automobile radar is changed continuously at a constant speed within a range of 360 degrees parallel tothe plane of four wheels of the automobile, the detection direction of the automobile radar is displayed in the automobile by a display device, and the display device or a sound device is used for prompting the information of the approaching obstacle. A device for implementing the method is composed of the automobile radar. The automobile radar is mounted on a rotating bracket, and the rotating bracket is connected with an output shaft of an electric motor through a speed changing device. An angle sensor is arranged in the rotating bracket, the angle sensor is connected with a display controller through a wire, and the display controller is connected with the display device. During automobile driving, the automobile radar continuously rotates at a constant speed. When the obstacle is detected within a detection radius, the current detection direction of the automobile radar is displayed on the display device, and a driver can know the surrounding conditions of the automobile in time.
Description
Technical field: [0001] The invention relates to the field of electricity, in particular to automobile electrical appliances, in particular to a method and a device for detecting dangerous approaching objects while the automobile is running. Background technique: [0002] In the prior art, the rearview mirrors of small passenger cars all have blind spots for observation, and the driver cannot fully understand the surrounding conditions of the vehicle, and accidents are prone to occur when changing lanes or reversing. Existing automotive radar uses ultrasonic transmitters and detectors to detect the existence and distance of obstacles, but it can only detect the situation within a fixed angle range behind the car, and its effect is limited. Invention content: [0003] The object of the present invention is to provide a method for detecting dangerously close objects while the car is running. The method for detecting dangerously close objects while the car is running is to so...
