Driver behavior characteristic identification device

Abstract

The invention provides a driver behavior characteristic identification device. The device comprises a real vehicle driving simulator experimental platform and a driver behavior characteristic identification method. The real vehicle driving simulator experimental platform comprises a real vehicle driving simulator experimental platform body, an operation table, a vehicle dynamics simulation model, a real-time simulating system, a steering force sense simulating system and a sensor system. The driver behavior characteristic identification method comprises the steps of establishing and verifying a driver behavior characteristic identification model, and then conducting driver behavior characteristic identification by means of the established driver behavior characteristic identification model. By the adoption of the real vehicle driving simulator experimental platform, a test platform similar to a real vehicle is provided for a driver, so that a data sample is acquired and preparation is made for establishing the driver behavior characteristic identification model. The interactive interface between the driver and the vehicle is fully considered, the driver feels like driving a real vehicle through simulation of vision, auditory sense and tactile sense, and the effect is vivid.

Description

Technical field [0001] The invention belongs to the field of automobiles, and particularly relates to a driver behavior characteristic identification device. Background technique [0002] The classification and identification of driver behavior characteristics is a necessary prerequisite for the development of personalized driving assistance systems and the realization of advanced technologies such as the ideal vehicle dynamics of "cars adapt to people". When different types of drivers drive vehicles, their ideal vehicle response characteristics are different. For example, racers like fast acceleration dynamics, and novices like steering performance with constant steering characteristics. The driving assistance system (vehicle control system) first recognizes the behavior characteristics of the driver, and then changes the response characteristics of the vehicle by changing related control parameters or switching control strategies to realize the active adaptation of the vehicle ...

Problems solved by technology

Its disadvantage is that the straddle vehicle required for the test is a special two-wheeled vehicle that needs to be customized; the test process requires a large number of expensive sensors to obtain vehicle, road, and road surface information; and the calculation process is complex and costly

The limitation of this invention is that it only relies on the state quantity of the vehicle to describe the driving style, ignoring the driver's operation behavior; in fact, the driver's operation behavior also includes a lot of content that reflects the driver's driving style. Although there is information redundancy between it and the vehicle state quantity, it should not be discarded easily; this invention only proposes a logical process of "car adapting to people", and does not clearly give the specific process of driver style identification and method
