FIELD: transport engineering.
SUBSTANCE: invention relates to methods aimed at increasing active safety of vehicles. proposed device includes system interrupting delivery of fuel, two pickups installed on axle and detecting side acceleration of axle and axle turning acceleration, two series-connected integrators for processing signals of pickups and generating variable components of side displacement and angle of turning, correlator arranged on automobile body with two pickups detecting side acceleration of body and body turning acceleration, shaft link multiplier and integrator designed for determining impulse transient functions of objects basing on variable components, device for determining absolute deformation of soil with possibility of transmission of data to input of electronic device determining critical speed of automobile which determines critical speed of automobile using frequency stability criterion, mismatching device breaking connection between accelerator pedal position pickup and electronic injection control unit at speed of automobile equal to critical one, thus limiting speed of automobile at straight-ahead running.
EFFECT: reduced limitation of maximum speed of straight-ahead running as to heading stability with due account of changes in dynamic characteristics of automobile and characteristics of soil.
