Title:
DIGITAL CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JPS5810246
Kind Code:
A
Abstract:

PURPOSE: To avoid the use of exclusive backup circuit and to suppress cost increase, by backing up the control of major functions of an engine electronic controller and a vehicle information offering device with each other, provided with microprocessors respectively.

CONSTITUTION: A part of various input signals inputted to a vehicle information offering device D/C2500, e.g., a vehicle speed signal 2534, is inputted also to an engine electronic controller E/C1000. On the other hand, a part of various input signals inputted to the E/C1000, e.g., an engine rotation signal (REF)201 and a cooling water temperature signal (Tw)231 are also inputted to the D/C2500. A signal 1041 is a pulse signal outputted when the E/C1000 is normally operated to check whether or not the operation of the E/C1000 is normal with the D/C2500 through the reception of the pulse signal 1041. Similarly, the E/C1000 checks whether or not the D/C is normal with the pulse signal 2540 generated from the D/C2500.
