The invention discloses a driving habit modeling method based on a driving simulator. The driving habit modeling method comprises the following steps of conducting a driver-in-the-loop simulation driving test on a simulation driver, and conducting whole-process video recording, wherein the working conditions of the simulation driving test comprise an urban road congestion road condition, an urbanroad non-congestion road condition, an expressway congestion road condition and an expressway non-congestion road condition, and the collected data comprises a vehicle following distance, a vehicle speed and an acceleration; calculating a maximum value, a minimum value and an average value of the vehicle following distance, a vehicle speed maximum value, a vehicle speed minimum value and a vehiclespeed average value, an acceleration maximum value, and a deceleration maximum value; calculating a legal acceleration lane change opportunity total amount and a legal deceleration lane change opportunity total amount according to the video, and calculating an acceleration lane change probability and a deceleration lane change probability; and establishing a test mixed working condition, and detecting the credibility of a driving habit model. According to the invention, a simulation driver is used to carry out a simulation driving test to realize driver driving habit modeling, the real vehicle test cost can be reduced, and a high-accuracy driving habit model can be obtained.
