| 摘要： | To obtain the effect of change in the horizontal curve feature on the steering behaviour of a passenger, vehicle driving behaviour when negotiating a simple curve (tangent + circular + tangent) was investigated.This research established a full dynamic model of a passenger car using Automatic Dynamic Analysis of Mechanical Systems (ADAMS) software.Virtual driving tests on simple curves with various parameters were conducted under two driving patterns: curve cutting and lane keeping respectively.Based on amplitude variation of angle input of the steering wheel, the steering process of a passenger car was divided into three stages: curve entry, maintenance, and curve exit.The steering lengths and steering times when the vehicle entered, remained and exited curves were obtained for each driving pattern respectively.The relationship between the two parameters and curve radius, deflection angle was thus acquired.On the one hand, this research can provide the control basis for parameter selection for curve geometry design, especially for assigning a value to spiral length.On the other hand, the correspondence between the steering wheel angle and the trajectory curvature allows us to identify the three driving states: straight driving, variable-curvature driving, and circular curve driving.This is helpful to an improvement in driver behaviour. |
