<p>PROBLEM TO BE SOLVED: To prevent errorneous explosion of an explosive left without ignited by only expanding a program of a controller without changing hardware configuration by consuming the residual explosive when occupants to be protected are in a safe position. SOLUTION: CPU 130 receives output information from an accelerating sensor 101 via an input interface 120. The accelerating sensor 101 measures and output the acceleration acting on occupants at all times. It is also provided with a timer mechanism, uses ROM 141, ROM 142 as memories, decides the ignition time of the residual explosive according to the algorithm and sends an ignition signal to an ignition drive circuit 161 or 162 via an output interface 150 at the right time. In receiving the ignition signal, the ignition drive circuit ignites the explosive substances 191, 192. The use of the acceleration sensor 101 for detecting the collision enables to ignite the residual explosive at a time when the occupants are supposed to reach a safe position.</p> |
