The article «Intelligent Stabilization safe speed of the car» deals with the optimal control problem on a finite time interval. It is presented in the form of a quadratic functional of quality control for active safety systems. The article also considers a vector of control actions on the controls. To solve its problem we use constraints which form the loss function of quadratic functional. Mathematical model of control object in the form of differential equations of longitudinal motion of the vehicle center of mass is considered in the problem. Plots of the traction vehicle acceleration from the control action on the throttle and the speed of center of mass in the mode of engine braking are given. In this article we reduce the one-step controller, which provides an exact solution of control problems in a single step calculation. A solution of control problems in the form of vector control actions for automatic transmission of the vehicle, its throttle and brake system is indicated. We show areas stabilized rates for the test vehicle for each of its live broadcasts. We also present the results of simulation system of dynamic stabilization of the vehicle speed in conditions of variable pitch angle. The results of the work are given.
