Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle-mounted radar, in particular to an automatic vehicle door anti-collision radar system. BACKGROUND

[0002] In recent years, with the progress of automobile technology, electric side opening doors are also becoming increasingly popular. Since the electric side opening door is automatically opened towards the side of the vehicle, if there is no obstacle avoidance function during the automatic opening process, it may collide with obstacles or persons within the range of the vehicle door; the vehicle may be damaged, and in severe cases, personal injury may occur. Based on this, a radar is arranged on the vehicle door for obstacle detection. There are currently three technical solutions for the detection radar: one is to arrange an ultrasonic radar through a hole in the vehicle door, which affects the appearance; the other is to arrange a hidden ultrasonic radar, which requires the addition of a shock-absorbing plate, increasing the weight of the vehicle body; the third is to arrange a millimeter wave radar below the vehicle door, which must be arranged with a vehicle door trim for radar wave penetration, and the size of the trim is too small to meet the arrangement requirements, affecting the overall appearance of the vehicle. SUMMARY

[0003] In view of the above, the present application aims to provide an automatic vehicle door anti-collision radar system to solve the aforementioned technical problems.
