Appeal No. 95-3377
Application No. 07/883,162
(a) an acceleration sensor for detecting acceleration of
a vehicle;
(b) acceleration correction means for multiplying said
acceleration from said acceleration sensor by a gain in order
to correct it;
(c) an EEPROM, numerical values equal to each other being
written, as said gain, into three or more memory areas of a
first group in said EEPROM, complementary numerical values of
said numerical values representing said gain being written
respectively into three or more memory areas of a second group
in said EEPROM;
(d) acceleration evaluation means for judging whether or
not a collision of said vehicle has occurred based on such
corrected acceleration, and outputting a trigger signal to
said vehicle safety device when the judgement result is "YES";
(e) gain setting means for setting said gain, said gain
setting means including (i) first means for judging whether or
not said numerical values representing said gain, stored in
said first group memory areas in said EEPROM are equal to each
other, and preliminarily determining said numerical value
belonging to the majority among all said numerical values
representing said gain as a temporary proper gain, (ii) second
means for judging whether or not said complementary numerical
values stored in said second group memory areas are equal to
each other, and preliminarily determining said complementary
numerical value belonging to the majority among all said
complementary numerical values, and (iii) third means for
judging whether or not said temporary proper gain is in
complementary relation with said complementary numerical value
belonging to the majority, and determining said temporary
proper gain as a proper gain under the condition that said
third means makes affirmative judgment, and further providing
said proper gain to said correction means; and
(f) alarm instruction means for actuating an alarm device
when said gain setting means makes at least one negative
judgment.
