Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawing:

[0044] The present invention provides a lane-changing device for autonomously learning the driver's lane-changing style, such as figure 1 As shown, it includes: a lane-changing style self-learning module 101, a lane-changing trajectory planning module 102, a lateral control module 103 and an execution system 104;

[0045] The lane change style self-learning module 101 is used to continuously obtain the completion time of the driver's single lane change , and select the effective lane-changing time from it, and then use the lane-changing style self-learning formula to obtain the driver’s lane-changing style time parameter t j ;

[0046] Among them, the lane change style self-learning formula is:

[0047]

[0048] In the formula, t min and t max are the lower limit and upper limit of the completion time of a single effective lane change respectively, α is a coefficie...

Abstract

The invention discloses a lane-changing device and method for autonomously learning the driver's lane-changing style, which can learn the driver's lane-changing style parameters-lane-changing time autonomously, and then use a polynomial method to plan the lane-changing path, according to the planned lane-changing Based on the path and vehicle dynamics control principles, the control parameters when the vehicle changes lanes are calculated; finally, the vehicle is controlled to change lanes according to the calculated control parameters when the vehicle changes lanes. The lane changing device and method for autonomously learning a driver's lane changing style of the present invention can adapt to the driving habits of different drivers.

Description

technical field [0001] The invention belongs to the technical field of vehicle lane change, and in particular relates to a lane change device and method for autonomously learning a driver's lane change style. Background technique [0002] With the rapid development of automatic driving technology, automatic lane change system has gradually entered people's field of vision. However, the traditional lane changing system has an invariable lane changing style, which cannot adapt to the driving habits of different drivers. Contents of the invention [0003] The technical problem solved by the present invention is to provide a lane changing device and method for autonomously learning the driver's lane changing style, so as to solve the problem that the unchanging lane changing style of the traditional lane changing system cannot adapt to the driving habits of different drivers. [0004] The present invention provides a lane-changing device for autonomously learning a driver's l...
