Method for in-vehicle communications during use of the vehicle, in which a first, data-processing component is arranged on the vehicle, at least one second component is arranged on a non-rotating part of the vehicle, each second component being a sensor arranged to measure a property of the vehicle or a component thereof or an actuator arranged to control a system, subsystem or other component of the vehicle, and the first and second components wirelessly communicate with one another. When the second component is a sensor, it wirelessly transmits data about the measured property and the first component receives the data wirelessly from the second component and processes the received data. When the first component is an actuator, it processes data relating to control of the second component and generates and wirelessly transmits signals to the second component to control the system, subsystem or other component of the vehicle.
