The proposed method allows evaluating an automobile handling with or without accounting withdrawal, with various types of drive wheels and various steering wheels using partial acceleration. Determination of lateral and tangential reactions on automobile tire while turning in view tire slip allows more accurate evaluating of automobile maneuverability, stability and handling. Determination of vehicle total and partial angular accelerations during its driving into rotation with and without accounting withdrawal allows developing an vehicles handling improving algorithm with different tire types. Using of different ways in vehicle managing is complicating associated with machine design and control process by machine handling characteristics changing during applying the locking devices. The equations of front-wheel drive vehicles and all-wheel drive vehicles rotational motion when driving on curves without removal are the same. Appearance of new ways to perform maneuvers such as turning movement with all the drive wheels (4WS), requires researching of movement trajectory, stability and handling of machines during specified maneuvering. The partial acceleration method allows the assessment of the controllability of vehicles with different types of drives (front-, rear - and all-wheel drive) and with different steerable wheels. The determination of lateral reactions on the wheels of the vehicle when turning allows for a more accurate assessment of the agility, stability and handling of vehicles
The method of testing vehicles for dynamic position stability has been improved, which makes it possible to assesstheir lateral stability when driving on irregularities. The dynamic stability coefficient is proposed for use as an assessmentcriterion. The application of the developed method allows to obtain an assessment of stability in real time during theoperation of transport means.The structural scheme has been developed to ensure the reliability of the operation of wheeled vehicle, based onreducing the influence of the driver's qualifications as an element of the "driver-vehicle-road conditions" system on itsposition stability, taking into account the results of monitoring the technical condition.To conduct experiments and evaluate the results, the mobile registration and measurement complex (MRMC) wasused to assess and improve the safety of exploitation of wheeled vehicles, taking into account modern means andapproaches. A single-board computer Raspberry Pi version 3B + serves as a platform for the mobile registration andmeasurement complex. The architecture of MRMC is modular; it supports the installation of additional inertial sensors,photo and video fixation devices, GPS, as well as devices compatible with USB. Operating system – Raspbian based onDebian distribution (GNU / Linux).To further automate the process of controlling a wheeled vehicle, the promising scheme for the operation of theregistration and measuring complex with elements of artificial intelligence was developed, which allows, without theparticipation of the driver, to carry out the necessary actions to control it and ensure, including operational safety.The results can be used to assess the suitability and performance of wheeled vehicles.
