Embodiment Construction

[0126] Such as figure 1 as shown, figure 1 , figure 2 , image 3 It is an EPS-based automatic parking route planning method and system proposed by the present invention.

[0127] refer to figure 1 , image 3 , the automatic parking route planning method based on EPS that the present invention proposes, comprises the following steps:

[0128] S1. Carry out parking space detection to obtain valid parking space information;

[0129] Specifically, it includes calculating the size of the parking space L according to the sudden change of the falling edge and rising edge during the detection process of the vehicle. p and the depth of the parking space S, and according to the size of the parking space L p and the depth S of the parking space to determine whether the current parking space information is valid parking space information;

[0130] Preferably, when L v ≤ L p lim 、S≥S lim , it is judged that the current vertical parking space is valid;

[0131] When L p lim 、S...

Abstract

The invention discloses an automatic parking route planning method based on an EPS. The method includes the steps: S1 detecting a parking space to obtain effective parking space information; S2 selecting a target parking strategy for a vehicle according to the effective parking space information, and guiding the vehicle to automatically enter an effective parking space to park according to the target parking strategy; S3 recording torque intervention intensity and torque intervention time on a steering wheel in automatic parking process of the vehicle, comparing the torque intervention intensity with a preset torque threshold value, comparing the torque intervention time and a preset time threshold value, and entering an assistant mode of the EPS when the torque intervention intensity exceeds the preset torque threshold value and the torque intervention time exceeds the preset time threshold value. The invention discloses an automatic parking system based on the EPS. A parking guide module selects target parking strategies according to results of a parking space detection module, and a mode switching module switches parking modes according to torque intervention intensity and torque intervention time on a steering wheel in the automatic parking process.

Description

technical field [0001] The invention relates to the technical field of automobile assisted driving, in particular to an EPS-based automatic parking route planning method and system. Background technique [0002] Nowadays, the development of automobile assisted driving is becoming more and more rapid. Both joint ventures and self-owned brand car companies have increased their research and development efforts. The development of automobile intelligence is the hottest trend at present. And the contradiction between the increasing number of cars in the city and the less and less available parking spaces has become increasingly prominent, and the difficulty of parking in the city has increased greatly. Therefore, the automatic parking system came into being. [0003] The Automatic Parking System (APS) is mainly composed of a perception unit, a central controller, a steering actuator, and a human-computer interaction system. The EPS is used as the APS actuator to execute the ste...
