Embodiment Construction

[0060] The technical scheme of the present invention will be further elaborated below in conjunction with accompanying drawing:

[0061] In order to realize the high-precision map-based automatic pick-up method in the parking lot in this embodiment, physical device support is required, that is, a high-precision map-based automatic pick-up system is provided, such as figure 1 , the system framework includes car terminal, mobile terminal and cloud.

[0062] Such as figure 1 As shown, the vehicle end includes a power module, a steering module, a braking module, a communication module, a GPS module, a perception module, and a driving control module. Since the power module, steering module, braking module, communication module, and GPS module are in common with conventional vehicle configurations The same, and will not be repeated here. The perception module includes 12 ultrasonic sensors, 4 millimeter-wave angle radars, 4 fisheye cameras, 1 front-view camera, and 1 millimeter-wa...

Abstract

The invention provides an automatic pick-up method and device for a parking lot based on a high-precision map, and a vehicle is enabled to drive to a designated position of a vehicle owner at a low speed for automatic pick-up in the parking lot where the scanning of the high-precision map is completed. The pick-up method is applied to the cloud server and comprises steps: receiving a pick-up instruction which is sent by each mobile terminal and carries the position of the user and a pick-up vehicle; acquiring the position of each pick-up vehicle; based on the position of each pick-up vehicle,calling a pre-collected high-precision map of the parking lot where each pick-up vehicle is located, taking the position of each pick-up vehicle as a starting point position, taking the correspondingposition of each user as an end point position, and planning a navigation path for enabling each pick-up vehicle to automatically drive from the starting position to the corresponding end point position; and sending the planned navigation path of each pick-up vehicle and the high-precision map of the parking lot where the pick-up vehicle is located to each corresponding pick-up vehicle, so that each pick-up vehicle automatically drives based on the received navigation path.

Description

technical field [0001] The present invention relates to the technology in the field of automatic driving, in particular to a method and device for automatically picking up a car in a parking lot based on a high-precision map. Background technique [0002] With the rapid development of the construction of large parking lots for homes and businesses, users need to spend a lot of time finding and parking their cars in the parking lot, and there is a risk of scratching at the same time. According to the preliminary research data, the Chinese per capita spends about 30 minutes in parking every day. Problems such as finding a car in the parking lot and novices in front blocking the driving route have long plagued car owners. With the continuous development of automatic driving, the automatic pick-up technology is the first step of automatic driving. It can save the time for car owners to find a car, improve the road safety in the parking lot, and alleviate the congestion in the pa...
