Method for propagation delay time reduction of operating system of motor car, involves transmitting output signal from main computing unit to start output of playback device, according to processing of input signal

摘要

The method involves detecting event in assistance computing unit (2) and comparing an event triggering input with a first condition. A switching signal (A') is sent to playback device (3), so as to switch on/off the amplifier (4), when event triggering input satisfies first condition. The input signal (B') for processing event triggering input, is sent from assistance computing unit to main processing unit (1), when preset condition is satisfied. An output signal (C') is transmitted from main computing unit to start output of playback device, according to the processing of input signal.
