Onboard network system for motor car, has control devices that include signal transmitter for transmitting modulated signal and reference signal to signal receiver for demodulation of modulated signal

摘要

The network system has control devices (3,4) that include a signal transmitter (1) for transmitting modulated signal and reference signal to a signal receiver (2) for demodulation of the modulated signal over a wireless vehicle network (6). The signal receiver demodulates the modulated signal using the reference signal in order to obtain original signal. The signal transmitter includes an oscillator to create carrier signal for modulating the original signal. An independent claim is included for data communication method used in onboard network system.
