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 the detection of dangerous approaching object during the driving of automobile. The method comprises the automobile radar installation steps on the automobiles and the detection process of the barrier distance by using the automobile radar. The method also comprises that the detection direction of the automobile radar is continuously and smoothly changed in the range of 360 degree, which is parallel with the four wheels plane of the automobile; the detection direction of the automobile radar is displayed in the automobile by using a display device; the barrier approaching information is suggested by using the display device or an acoustic device. The device which implements the method is composed of the automobile radar; the automobile radar is mounted on a rotation bracket, which is connected with an output shaft of a motor through a speed variation device; an angle sensor is mounted in the rotation bracket, which is connected with a display controller through the wire; the display is connected with the display device. During the driving of the automobile, the automobile radar rotates continuously and evenly; when the barrier is detected in the detection radius, the current detection direction of the automobile radar is displayed in the display device; the driver can understand the situation around 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...
