Abstract
An apparatus for determining emergency conditions of a vehicle including: an acceleration sensor which detects the acceleration of a vehicle and an operation-signal generating apparatus which establishes a signal level based on the signal outputted from the acceleration sensor in a circuit established in accordance with the kind of vehicle collision and which outputs a signal for actuating a passenger safety device when the established signal level exceeds a reference value which is predetermined according to the kind of vehicle collision. This allows the passenger safety device to be actuated at a suitable time according to vehicle collision.
