To realise the interface it is necessary to lay along the perimeter of the vehicle one signal wire and one information wire. Information about the state of all sensors of the vehicle will continuously enter the CCP (central control panel) from all PD's (peripheral devices) in turn whilst every PD will select from the common information flow the data for its actuators. Because information enters from the CCP by packages (frames) a small delay could be between works of sensors and correspondent actuators. This delay in limit case achieves the width of one package of polling impulse. For the beat frequency 10 kHz when the vehicle contains up to 256 sensors and up to 256 actuators maximum delay will be 25 ms that is unimportant in most cases. At the same time this delay can be reduced down to 100 ns by careful numbering of the sensors and actuators. Simplicity of the devices being the components of the considered interface allows to recognize advisability of its application in modern vehicles.
