Control system for a vehicle safety device with eeprom memory for

Abstract

A system for controlling an object such as a vehicle safety device, comprises an EEPROM. A microcomputer is operated to multiply a sensing data such as acceleration by a gain in order to correct it, and control the object based on the corrected sensing data. The EEPROM has three or more memory areas of a first group, and the same number of memory areas of a second group. Numerical values equal to each other are written respectively into the first group memory areas as the gain, and complementary numerical values of the numerical values representing the gain are written respectively into the second group memory areas. The microcomputer is operated to check the data in the EEPROM. An alarm device is actuated when the microcomputer detects that the data is abnormal. A numerical value which belongs to majority in the first group memory areas in the EEPROM, and which is also in complementary relation with a complementary numerical value belonging to majority in the second group memory areas, is selected so as to be used as a proper gain.
