Automatic parking method based on memory parking

Abstract

An automatic parking method based on memory parking comprises the following steps: S1, automatic parking is conducted in response to the operation that a user presses down an automatic parking key, and an ECU stores the position of a parking frame, the type of parking and the position at the beginning of a parking action in the current automatic parking process to form a parking record; S2, afterthe vehicle is started, the ECU can intermittently obtain the current position information of the vehicle from a positioning device installed in the vehicle, the current position information is matched with the parking record, whether the vehicle enters the memory parking field or not is judged, step S3 is executed if so, and step S2 continues to be executed if not; S3, the ECU further judges whether the current driving direction of the vehicle is driven into the field from the outside of the memory parking field or not, the ECU controls a message reminding module to remind the driver if so inorder to enter the step S4, and the ECU returns to the step S2 if not; and S4, if the ECU detects the operation that the user presses down the automatic parking key within the preset time, a parkingpath is planned according to the record, and automatic parking, otherwise, canceling the automatic parking are carried out.

Description

technical field [0001] The invention relates to the field of sensor data perception and decision-making planning in the field of automatic parking, and more specifically relates to an automatic parking method based on memory parking. Background technique [0002] The core of the automatic parking function includes sensor data perception, fusion, decision planning, and control. Among them, the perception of sensor data is the first step in the realization of the automatic parking function, and decision-making planning is a direct manifestation of the intelligence of the autonomous parking system. [0003] The safety of automatic parking is the primary condition for automatic parking. At present, the activation of the automatic parking function, the selection of the parking type, and the selection of the parking position all require manual operations by the driver. Some of these operations are performed while the vehicle is running, which will distract the user's attention a...

AI Technical Summary

Problems solved by technology

Some of these operations are carried out while the vehicle is in motion, which will distract the user's attention and bring potential safety hazards

In addition, the user operation is too cumbersome, and the user experience is not good
