摘要： 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.

摘要： Activators for a plurality of safety devices are connected in parallel relation to each other and connected to a common power source. Switching elements are connected in series to the activators respectively. A common safety switch is connected in serial relation to the activators and connected to the power source. This safety switch is turned on by a lower level of shock than that which is judged as a vehicle collision by a micro computer. The micro computer judges whether or not the vehicle has collided based on an acceleration information from an acceleration sensor. The micro computer controls the switching elements such that the switching elements are cyclically and alternately turned on at the moment a vehicle-collision judgment is made.

摘要： A system for controlling a safety device for a vehicle includes first and second switching elements connected to a power source in serial relation to the safety device. The control system further includes a pair of acceleration sensors, a pair of analog processing circuits, and a microcomputer. In accordance with an deceleration signal from the corresponding acceleration sensor, each analog processing circuit outputs a collision decision signal. In accordance with the signals from the acceleration sensors, the microcomputer makes calculations to output two collision decision signals respectively from two output ports thereof. The control system further includes two logic elements. One of the logic elements, when simultaneously receiving any two out of the above four collision decision signals, turns on one of the two switching elements. The other logic element, when simultaneously receiving the other two collision decision signals, turns on the other switching element. When both of the two switching elements are turned on, the safety device is operated.

摘要： If the impact acceleration G which exceeds the predetermined threshold value G.sub.TH is detected within a predetermined time (see step 124 in FIG. 2) after the speed integral value .DELTA.V which exceeds the predetermined threshold value V.sub.TH has been detected (see step 112 in FIG. 2), it is decided that such impact acceleration is caused by the underfloor interference or the seat slide and therefore the side air bag system is not started (see step 126 in FIG. 2). In contrast, if the impact acceleration G which exceeds the predetermined threshold value G.sub.TH is not detected within the predetermined time (see step 124 in FIG. 2) after the speed integral value .DELTA.V which exceeds the predetermined threshold value V.sub.TH has been detected (see step 112 in FIG. 2) it is decided that such impact acceleration is caused by the true clash and therefore the side air bag system is started (see step 120 in FIG. 2).

摘要： A control system for a vehicle safety device comprises an operation circuit in which a main switching element, an activator, and a safety switch are connected, in series, to a condenser for accumulating electric power. When a vehicle collision has occurred, the safety switch is turned on and the main switching element is turned on in response to a vehicle collision judgment which is made in accordance with a signal from an acceleration sensor. As a result, electric current is supplied to the activator to activate the vehicle safety device. The main switching element is turned off when a time period where an output of an operation instruction signal for actuating the main switching element and the ON-state of the safety switch are realized reaches a preset time period.

摘要： A control system for a vehicle safety device includes a drive circuit. The drive circuit includes a main switching element, and a safety switch which is turned on by an inertia force produced at the time of a collision of the vehicle. The vehicle safety device is activated when the main switching element and said safety switch are both turned on. The control system further includes an acceleration sensing circuit for detecting deceleration of the vehicle, and a microcomputer. The microcomputer judges, based on a deceleration signal from the acceleration sensing circuit, whether or not a collision has occurred, and outputs an ON-instruction signal to the main switching element when the microcomputer judges that the collision has occurred. The microcomputer also judges whether or not the acceleration sensing circuit is subjected to a malfunction, and judges whether the safety switch is in the ON state or the OFF state. The microcomputer outputs an ON-instruction signal to the main switching element when the microcomputer judges that the acceleration sensing circuit is subjected to a malfunction and at the same time when the microcomputer judges that the safety switch is in the ON state.

摘要： A control system for a vehicle safety device includes a pair of acceleration sensing circuits. The outputs of the acceleration sensing circuits correspond to a deceleration of the vehicle in a direction of running of a vehicle, and are in opposite phase with each other. A differential calculation device effects calculation in accordance with the difference between the outputs of the acceleration sensing circuits, so as to cause noises, applied to the acceleration sensing circuits, to cancel each other, thereby preventing an inadvertent activation of the vehicle safety device due to such noises. According to another alternative construction, in order to prevent the inadvertent activation of the vehicle safety device due to the noises, the opposite-phase outputs of the pair of acceleration sensing circuits are integrated by a pair of integrating circuits, and a pair of collision judgment circuits compare the outputs of the integrating circuits with respective threshold levels so as to judge whether a collision has occurred.
