Abstract

The invention provides a parking obstacle detection method and device. The method comprises the following steps of: starting an ultrasonic sensing device to collect and obtain multiple sets of obstacle distance information; solving a difference value between each piece of distance data in the next group of obstacle distance information and one piece of distance data in the previous group of obstacle distance information; screening out candidate difference values within the dynamic range from the difference values; screening out the candidate difference value with the minimum later distance data from the candidate difference values to serve as a target candidate difference value, and determining the front distance data and the rear distance data corresponding to the target candidate difference value as dynamic trajectory data of the nearest obstacle; and outputting alarm information according to the dynamic trajectory data. According to the parking obstacle detection method, multiple sets of obstacle distance information can be collected, real obstacles and false obstacles can be screened out, two pieces of dynamic trajectory data of the real obstacle closest to the automobile are obtained, and warning information is output according to the dynamic trajectory data of the closest obstacle to assist a driver in parking operation.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a parking obstacle detection method and a parking obstacle detection device. Background technique [0002] With the development of social economy and industrial technology, automobiles, as a modern product that promoted the previous leap forward of human civilization, have gradually become people's daily necessities and one of the most common means of transportation in today's society. In the process of driving a car, parking behavior is an indispensable operation in the process of using a car, but because the parking behavior is relatively complicated, accidents are prone to occur. Therefore, automobile manufacturers have designed parking assistance systems for automobiles to detect whether there are obstacles around the automobile when parking, and remind the driver of the existence of obstacles in time to reduce or avoid parking accidents and improve the ...
