In most cases, installing a capacitive fuel level sensor on passenger cars is a difficult task. The design features of the body do not allow to cut the
fuel level sensor into the fuel tank. In such cases on-board controllers of satellite monitoring GLONASS/GPS are connected to the CAN-bus of the vehicle.
The abbreviation CAN is formed from the word combination: Controller Area Network and literally translated as - a network of controllers.
Modern cars and trucks are equipped with CAN-buses. CAN-bus provides two-way communication with various devices, so that they can be controlled and instantly receive information about their status.
With the development of telematics technologies, CAN-based solutions for remote interaction with the vehicle have been developed. For example, for remote diagnostics, vehicle security and satellite monitoring.
