The Increase of Stability of Motion of a Two-axle Cars with Automatic Correction Angle Steering Wheel
Zhileykin M.M., Chulyukin A.O.

Examining trends in the automotive industry, you can see that manufacturers are constantly improving the level of control
over the parameters of motion of wheeled vehicles, achieving the maximum level of stability and controllability of the car.
The use of systems and corrective management wheels has three objectives. The fi rst is to get the variable car sensitivity to
the steering wheel. The second objective is to improve the manoeuvrability of the vehicle when parking or spread in cramped
urban conditions, i.e. decrease the radius of the turn. And the third is to improve directional stability at sudden movements
at high speed. The offered algorithm of the automatic correction angle steering wheel (steering)enhancing the exchange rate
trajectory and stability of two-axle wheeled vehicle, as well as the criterion of effi ciency of work of the stabilization system that
allows you to compare different algorithms in the same operating conditions. Methods of simulation modeling found that the
most effective for two-axle car is the stabilization algorithms used in combination with low power consumption of the engine
+ Taxiing, which ensure the increase of the accepted criterion of the effi ciency of the system of stabilization of 12...93 %. The
effect of the application of each of these algorithms separately much lower (4...28 %), and sometimes, they can only worsen the
quality control car.
The results of the research can be useful to the enterprises of motor industry, specializing in design and manufacture,
fi rst of all, a two-wheeled vehicles of various classes and purposes, as well as organizations develop management systems for
wheeled transport equipment.
Keywords: wheeled vehicle; active safety; control algorithm; mathematical model; simulation modeling; stability;
controllability; steering.
