Abstract
The paper presents a driver model, which can be used in a
computer simulation of a curved ride of a car. A computer
simulation of the curved ride and directional control of the car
plays a significant role in a study of vehicle active safety, as
the cheapest and safest investigation method. An analysis based on
an advanced dynamic vehicle model only is not satisfactory in many
cases, when an interaction between the driver and the vehicle is
not to neglect. The double lane change maneuver (ISO/TR 3888) is an
example of the typical test procedure in which the vehicle-driver-
environment model should be taken into consideration.
In elaborated driver model it is assumed that the visual signal
is most important for a directional control of the car. The driver
model is described by three parameters: aim point distance,
response delay and steering angle gain.
The driver model can be used in studies of vehicle handling and
stability when closed-loop procedures are needed. Examples of the
model application in computer simulations of such test procedures
as the double lane change maneuver and the wind gust maneuver are
presented in the paper. It is shown that the use of the driver
model in computer simulation of the car motion allows adapting
better the car construction and its dynamic properties to the
psychophysical characteristics of the driver and thus can
contribute to improve the active safety of the car.
