Problems solved by technology

The existing LDWS monitors the lateral position of the vehicle in the current lane in real time, compares it with the set alarm distance, and judges whether to give an early warning, and uses whether the turn signal is turned on as the suppression algorithm for the early warning. However, when the driver is changing When the turn signal is not turned on during the road, the lane departure warning system will frequently warn the driver by means of vision, sound or even steering wheel vibration, which will cause the driver's mental stress, thereby reducing the driver's trust and acceptance of the system. This in turn affects the promotion and use of the system

Embodiment 1

[0066] This embodiment provides a method for recognizing a driver's lane-changing intention, which includes the following steps: inputting current vehicle driving data into a driver's lane-changing intention recognition model to output a recognition result of the driver's lane-changing intention, wherein the driver The construction process of the lane-changing intention recognition model includes:

[0067] S1. Collect historical vehicle travel data, and generate associated parameters related to the vehicle lane-changing process based on the historical vehicle travel data. Specifically include:

[0068] S11. Test platform

[0069] This test uses the RADS 8-DOF panoramic driving simulation system developed by the Research Institute of Highway Science (RIOS) of the Ministry of Transport. The driving simulation system is mainly composed of 6DOF, Yaw-Table, Vibration, X-Table, cabin, multi-channel projection system, sound system, power supply system and other auxiliary systems. ...

Abstract

The invention relates to a method and system for identifying a driver's lane-changing intention, using a decision tree method to extract the steering wheel angle, lane departure amount and yaw angular acceleration as an intention characterization parameter group; based on K-means clustering, the steering wheel angle and lane departure The time series of the quantity are clustered separately to determine the start and end moments of the intention, and then determine the time window width of the lane-changing intention; finally, combining the Gaussian probability density function and the hidden Markov theory, a recognition model of the driver's lane-changing intention is established to identify the driver's intention. The recognition reliability is high, the recognition accuracy rate of left and right lane change intentions is 100%, and the recognition accuracy rate of straight travel intentions is 91.1%, and the timing is strong. Predicting the lane-changing behavior 1.4s before the start of the lane and preventing the interference caused by the LWS system to the driver are of great significance to improving driving safety and reducing traffic accidents.

Description

technical field [0001] The invention relates to the technical field of driving safety of motor vehicles, in particular to a method and system for identifying a driver's lane-changing intention. Background technique [0002] With the development trend of automobile intelligence, Advanced Driver Assistance System (ADAS) is gradually applied to vehicle driving, in order to better assist the driver in driving and improve driving safety. Among them, the Lane Departure Warning System (LDW) can timely and effectively warn the driver to correct the unconscious lane departure, so as to effectively prevent the driver from deviating from the driving track due to factors such as distraction or driving fatigue and causing traffic accidents. The existing LDWS monitors the lateral position of the vehicle in the current lane in real time, compares it with the set alarm distance, and judges whether to give an early warning, and uses whether the turn signal is turned on as the suppression alg...
