“…EBD, які застосовуються на легкових автомобілях представницького класу, що експлуатуються в умовах розгалужених мереж автобанів та автомобільних доріг покриття, використовують блоки чутливих елементів, що містять датчики кутових швидкостей коліс автомобіля та допплерівські датчики швидкості руху центру мас [11][12][13][14][15]. У складних дорожніх умовах, коли система ABS не може забезпечити якісне розблокування коліс у процесі екстреного гальмування, така структура EBD не може задовольнити високим вимогам точності стабілізації корпусу автомобіля щодо заданого напрямку.…”

Unsatisfying state of domestic highways՚ road surface and low technical quality of domestic cars lead to high accident rate on roads. Accidents involving large vehicles equipped with 20–22 m3 tanks transporting fuel and aggressive liquid chemicals are particularly serious. The article considers the problem of creating on-tank vehicles direction stability systems with digital stabilizer, which provides high accuracy of stabilization of the car body in emergency braking due to the use of stabilizer algorithms of platformless inertial systems, as well as the choice of certain values of variable stabilizer parameters. The mathematical model of perturbed motion of the stabilization object considers the oscillations of the free surface of the transported liquid, which allowed to study the effect of these oscillations on the stability of a closed stabilization system and accordingly choose the range of allowable values of variable parameters. This computational procedure is a combination of two optimization methods — the scan grid method of Sobol for finding the global minimum zone and the Nelder-Mead method, which is implemented by the software product «Optimization Toolbox» of MathLAB package. The procedure also, in parallel with the numerical solution of the optimization problem, selects the values of the weights of the additive functional. As a result of solving the problem of parametric synthesis, the values of the varied parameters of the digital stabilizer are obtained, which provide high accuracy of stabilization of the tanker car body relative to a given trajectory in the mode of emergency braking.

The problem of constructing the invariant stabilizer of the ESP (Electronic Stability Program) car course stability system is considered by implementing two control principles by the electronic brake force distribution unit EBD (Electronic Brakeforce Distribution) – the principle of control by deviation and the principle of control by external disturbance. The values of the variable parameters of the stabilization algorithm are selected from the conditions for minimizing both the static and dynamic errors of the system. Two brake fluid pressure sensors are introduced into the EBD structural-functional scheme in the brake lines of the right and left sides of the car. It is proven that the pressure difference of the brake fluid, which is measured by pressure sensors, is proportional to the external disturbance acting on the car body from the side of the road surface. Therefore, in order to give the ESP system the property of invariance to external disturbances, the control signal generated by the EBD electronic unit contains current information not only about the parameters of the disturbed movement of the car, namely, about the angle of deviation of the longitudinal axis of the car relative to the given direction of movement, about the angular velocity of rotation of the body relative to its vertical axis and about lateral displacement of the center of mass of the body, but also the current information about the external disturbance acting on the car body. Recommendations for choosing the values of variable parameters of the ESP system stabilizer are given, which ensure the minimization of both static and dynamic errors of the closed system in the emergency braking mode.

The world experiences continuous development from time to time which encourages progress in various fields of life, one of which is technology. Technology has developed significantly due to the influence of people's lives which are always changing dynamically. Various automotive industries that compete with each other to present dream vehicles that can support people's lives in every condition. Innovations developed by various automotive industries are based on the basic human need for safety and comfort which is the main goal so that all innovations are always a top priority because in an era that continues to develop everything is forced to always be done quickly. One of them is the Braking system which has a function to slow down and stop the speed of a vehicle which is analyzed using direct observation methods with systematics using flow charts to determine the effectiveness of the Potential Braking System on Isuzu Mux Cars Based on Braking Torque, Braking Time, and Braking Distance which are reviewed from various perspectives. The condition of the road surface, the type of material used, and the various levels of speed so as to determine the best braking potential possessed by the Isuzu Mux car to support safety in driving on the highway.
