<p>PURPOSE:To prevent the loss of the function of a system and adverse influence upon other electronic control units(ECU) which are connected to a common bus line while put in partial charge of the function by enabling an ECU to be reset individually to interchange necessary data with an ECU which is relative in function when the ECU is reset. CONSTITUTION:If a 2nd arithmetic processor 7 is shut down individually owing to disturbance such as a noise and a power drop due to an environmental difference in the individual installation on a moving body among a 1st arithmetic processor 3, the 2nd arithmetic processor 7, and a display controller 10, a reset signal indicating that the 2nd arithmetic processor 7 itself is reset is sent out to the common bus line(BUS) when the 2nd arithmetic processor 7 is reset after the noise disappears or the power source recovers. The latest data which are rewritten while the 2nd arithmetic processor 7 is shut down are interchanged for the recovery. Consequently, the function loss of the system and adverse influence upon other electronic control units(ECU) are prevented.</p> |
