摘要:
A system for controlling an object such as a vehicle safety device comprises a microcomputer, and reset circuits. The microcomputer judges whether or not an identification data is stored in a specific area of the RAM in order to identify the kind of the resetting method. If the judgment result is "NO", the object is controlled after an early judgment of the control system is effected. In contrast, if the judgment result is "YES", the object is controlled without effecting the early checking.
摘要:
In a control apparatus that activates a preloader device and after a timing delay an air bag device when a vehicle collision is detected, the apparatus has a detector for detecting whether or not a seatbelt is buckled, and a timing signal for activating the air bag device is generated without the timing delay if the seatbelt is not buckled, whereby the air bag device can be activated with a timing appropriate to the condition present at the time.
摘要:
A control system for a vehicle safety device includes an acceleration detecting device for detecting the deceleration of the vehicle, an integrating device for integrating the deceleration from the acceleration detecting device, a collision judgment device for comparing the integral value, obtained by the integrating device, with a trigger threshold level so as to judge whether or not a collision has occurred, and for outputting an activation instruction signal when the collision judgment device judges that the collision has occurred, and a drive circuit responsive to the activation instruction signal from the collision judgment device so as to activate the vehicle safety device. The control system further includes a deceleration compensation device for adjusting the trigger threshold level in accordance with the deceleration in such a manner that the trigger threshold level becomes low when the deceleration is large and that the trigger threshold level becomes high when the deceleration is small.
