Establishing of causes and circumstances that could affect failure of both parts individually and mechanisms generally of the “Active curve system” active stabilization system in Mercedes-benz GLS500 4MATIC cars is considered. The relevance of this scientific paper is due to novelty of installing an active stabilizer on vehicles which ensures minimal car body roll. Design, a principle of work and forensic expert research while inspection and study of the “Active curve system” active stabilization system of Mercedes-benz GLS500 4MATIC using modern equipment and research methods are presented. Measures to prevent failure of structural parts and systems are considered, which will ensure reliable and safe work of the “Active curve system” active stabilization system in the process of operation. The system allows you to keep a car within the path set by a driver in various driving modes (acceleration, braking, moving along a straight line, while road curves and free rolling). Determination of occurrence of a traffic collision is carried out by comparing actions of a driver and parameters of a car. In case when a driver’s actions (desired driving parameters) differ from the actual vehicle motion parameters, the “Active curve system” active stabilization system recognizes the situation as uncontrolled and starts working. In case of understeer, the “Active curve system” active stabilization system prevents a car from slipping out of turning trajectory by slowing down a rear inner wheel and changing an engine torque. In case of oversteer, skidding of a car during turns is prevented by slowing down a front outer wheel and changing an engine torque. Operation in this case is of a cyclical nature: pressure increase, pressure containment and pressure relief in the “Active curve system” active stabilization system. The system that combines the system of electronic stability control, steering and car suspension is called vehicle dynamics management integrated system.
