This article describes experimental research results of the inductive sensor of the electropneumatic clutch control system for the mechanical transmission. Inductive sensors are used to determine the position of the car body, the position of the controls and the position of the rod of the clutch control actuator. The design of the clutch pedal position sensor is proposed, which can be brought into line with the master cylinder to unify the clutch control systems. Complete unification of the automated electropneumatic clutch control system for trucks will allow creating modifications in which it is possible to completely abandon the use of brake fluid in the drive, which will improve the ergonomic and environmental performance of the vehicle. The advantages of such sensors are the ability to receive a signal in digital form without additional converters, the ability to work using only two wires, no contact between moving parts, resistance to aggressive environments and compact size.

One of the reasons for the large number of road accidents on highways in Ukraine [1] is the instability of the braking properties due to the unstable characteristics of the brake mechanisms’ friction pairs. The manufacturer produces new automobiles with installed brake pairs (brake pads and their counter bodies), which have passed long-term tests for the stability of the friction coefficient and braking forces distribution of between the axles. This ensures the compatibility of the friction pairs characteristics for front and rear brake mechanisms according to the criteria of heat resistance. During operation, instead of worn-out brake pads, brake discs and drums, drivers can purchase new ones, manufactured as spare parts. However, in the well-known literature there are no methods that allow to check the compatibility of the friction pairs characteristics for front and rear brake mechanisms according to the criteria of heat resistance.
