Researching the Possibility of Wireless Energy Transmission for the Power Supply Condition Monitoring System of a Car's Suspension

The work proposes a block diagram of a system for condition monitoring the robustness of a vehicle's suspension. At the same time, the features of constructing such a system are considered and the justification of the technical implementation of its functional elements is carried out. It is proposed to transmit the suspension's state data to the vehicle's on-board computer via a radio channel, and to supply power to the sensor subsystem using the wireless energy transmission system (WPT). To this purpose, preliminary calculations of the power consumption of the suspension monitoring subsystem and the required level of microwave power of the WPT system transmitter were carried out. An approach to the analysis and calculation of the influence of the car's suspension design on the electrodynamics characteristics of antennas in the WPT system and taking into account the electrodynamics interaction of the elements of the WPT system with other radio electronic means of the car is described.
