The process of lifting and lowering the roof of the car in most modern cars includes a number of complex and synchronized events coordinated by the microcontroller. The automobile market offers a soft and hard, hinged top using various methodologies to fold the roof. Soft roofs are of different types, but most soft roofs use the basic mechanism of the Z-scheme. The folding solid upper parts can consist of 1 to 5 independent panels that are folded on each other, and then cleaned into the trunk cavity. Regardless of the type of design, the convertible uses several position sensors to control the movements of the folding top, providing safe work that will not harm passengers. Most modern mechanisms use a series of hydraulic drives. These are very compact hydraulic pumps, usually installed in the trunk. A series of valves and solenoids control hydraulic power to correctly move each component. The entire system with a folding top, as a rule, is controlled and controlled by an independent control module. This module usually contains a microprocessor and uses CAN communication to interact with other systems and receives information such as the speed of the vehicle and the user request to perform the operation through the distance keychain. After receiving a request for work and confirmation that some parameters are within their permissible limits, the converting control module initiates the sequence of events that are necessary in order to raise or release a folding top.
