Problems solved by technology

However, the current patents or products cannot fully understand or capture people’s real intentions and changing trends in real time. When the driver’s environment changes due to the vehicle’s surroundings, such systems often issue alarms or perform actions that are different from the driver’s intentions. On the contrary, it distracts the driver and causes accidents

example

[0053] For a total mass of 1296kg, the moment of inertia around the Z axis is 1750kgm 2 , a wheelbase of 2.57m, a distance from the center of mass to the front axle of 1.25m, a distance from the center of mass to the rear axle of 1.32m, a front wheelbase of 1.405m, a rear wheelbase of 1.399m, a height of the center of mass of 0.45m, and a wheel radius of 0.326m. authenticating. The vehicle speed is increased from 0km / h to 13km / h, and the emergency barrier and curve braking are completed at the same time. The road surface friction coefficient is set to u=0.7, which is the normal friction coefficient of dry asphalt road.

[0054] figure 1 As shown, the driving intention recognition first collects all kinds of driving behavior data required, after data preprocessing, selects eigenvalues ​​for each data segment, and uses the eigenvalues ​​to eliminate abnormal data, and uses the clustering algorithm to determine each driving behavior. All data groups are divided into data sets o...

Abstract

The invention provides a driver intention recognition method. A double-layer recognition structure is proposed based on a multi-dimensional discrete hidden Markov model, behaviors and intentions of a driver are respectively recognized, the behaviors of the driver serve as input for recognizing the intentions of the driver, and recognition accuracy and reliability are enhanced. According to vehicle operating information and vehicle speed, the current operating intention of the driver can be accurately judged, so that conditions are created for improving a vehicular safety auxiliary system.

Description

technical field [0001] The invention belongs to the technical field of vehicle recognition, and more specifically relates to a driver's intention recognition method to realize the recognition of the driver's intention to control the vehicle. Background technique [0002] In order to realize the automotive safety assistance system technology, it is first necessary to recognize the driver's intention and predict the driver's behavior. [0003] In the special topic "Integrated Transportation System and Safety Technology" set up in the "863 Plan", the topic "Driving Behavior Monitoring and Early Warning Technology and Equipment" was proposed, and its research objectives were clarified: through the research and development of abnormal driving conditions, illegal operations, bad Driving habits and other monitoring and early warning systems and devices form a real-time monitoring technology for driver behavior. However, the current patents or products cannot fully understand or ca...
