Composite type parking sensor

Abstract

The invention relates to a composite type parking sensor. A plurality of image-capturing elements and ultrasonic probes are arranged on the head and the rear of an automobile respectively and are connected with a control main machine respectively which is respectively connected with a speed detector and a gear detector. An automobile-borne display is arranged on the output end of the control main machine. The control main machine can selectively start the image-capturing elements and ultrasonic probes on the head and / or the rear of the automobile according to the detected speed and gear, and display the cut image with overlapped barrier distance on the automobile-borne display. Therefore, the sensor can expand the visual range of a driver, assist the driver in knowing the environmental conditions around the automobile, and ensure the safety of driving.

Description

technical field [0001] The invention relates to a composite reversing radar, especially a composite reversing radar that effectively integrates an image capture element and an ultrasonic probe, cooperates with signal integration and image processing technology, and has the ability to expand the driver's field of vision and produce an early warning effect to ensure driving safety. Reversing radar. Background technique [0002] In order to assist car drivers to successfully complete roadside parking and reversing, or to effectively grasp the situation behind the car during driving, a camera is installed at the rear of the car, and the images captured by the camera are sent to the monitor in front of the driver's seat for driving It is a known technology for people to grasp the situation outside the vehicle. The reversing radar is also a known auxiliary device for automobiles. The reversing radar in the early years was installed on the rear bumper of the car. To assist the dr...

Problems solved by technology

[0003] Furthermore, during the driving process of the car, there are some situations that cannot be assisted by the existing auxiliary devices, such as Figure 7 As shown, because there is still a short distance between the front of the car and the driver's seat, when the car passes through the narrow alley and advances from the narrow alley to the intersection, the situation at the front of the car cannot be known immediately due to the distance between the front of the car and the driver's seat. Once there are other cars coming forward at the intersection, it may cause the driver to react too late and cause a car accident

[0004] And when the car backs up on a road section with too large turning angle, or exits from a relatively narrow alley, affected by the aforementioned factors, its danger still exists, such as Figure 8 As shown, when the car 70 intends to back up and leave the parking lot, in this situation, the car 70 completely relies on the information provided by the left and right rearview mirrors 71 and 72 provided on both sides of the driver's seat for the control of the rear situation. However, it can be clearly seen from the figure that the left and right rearview mirrors 71, 72 sight lines of the automobile 70 (shown in the dotted line area) are blocked by vehicles parked on both sides adjacent to each other. If the car 70 in the car fails to detect this situation in time, a collision accident may occur

[0005] Furthermore, the roads on which cars drive often have potholes due to excavation and construction. Those potholes may cause discomfort to cars due to upside down, and cause accidents and endanger lives if they are serious. , also have to be careful
