摘要： An electric control circuit for a passenger protection system in an automotive vehicle includes an electric power source, an acceleration sensor arranged to produce an acceleration signal therefrom in the occurrence of a vehicle collision and an electrically operated actuator including a primer having a first terminal in series with the power source and a second terminal in series with the acceleration sensor to be grounded therethrough in response to the acceleration signal from the sensor, wherein the second terminal of the primer is directly grounded when a voltage appearing at a conductor between the second terminal of the primer and the acceleration sensor becomes lower than a predetermined value to ensure activation of the primer.

摘要： Air bags are located at different positions within a vehicle. Squibs serve to fire and activate the air bags respectively. An acceleration detecting device is provided in common to the squibs for detecting an acceleration of the vehicle upon a collision of the vehicle and executing a switching operation in response to the detected vehicle acceleration. Constant-current circuits supplied with an electric power from a vehicle battery feed constant electric currents for a firing operation to the squibs respectively in response to the switching operation of the acceleration detecting device. An energy storage device serves to feed a backup electric power to the constant-current circuits when the supply of the electric power from the vehicle battery is cut off. Each of the constant-current circuits includes a first transistor for feeding an electric current to the related squib, a first resistor for detecting a level of the electric current fed to the squib, a second transistor conducting an electric current with a level which depends on the electric current level detected by the first resistor, and a second resistor for generating a voltage which depends on the electric current conducted by the second transistor and for controlling the first transistor in response to the generated voltage.

摘要： A vehicle operator protection system includes an actuating device, a battery for supplying the actuating device with electric power, and a backup capacitor charged by the battery and supplying power to the actuating device when the battery becomes inoperable. It further includes a switch for cutting off the power supply from the battery and a determining circuit for detecting a discharging condition of the backup capacitor after it has been cut off from the power supply with the switch to determine the existence of an abnormality in the backup capacitor and the actuating device. Through the detection of the discharging condition of the backup capacitor, determination of the existence of an abnormality, based on the intended function of the backup capacitor, can be achieved.
