A starting device integrates an output signal of an acceleration sensor by a band-pass integrating means while restricting an upper limit of the output signal in a specified frequency range by an upper limit restricting means, and is provided with a comparing means for outputting a starting signal when the integrated value is larger than a predetermined threshold value. In this way, the starting device is certainly started by an acceleration waveform of collision that must start the device. Further, the device is not influenced by vibration components caused immediately after the beginning of collision with respect to a low-speed collision such as 8 mile/hour frontal collision that must not start the device.

Starting device for a passenger protecting device

A starting apparatus for a passenger protecting apparatus includes a collision deciding unit, a control unit, and a trigger. The collision deciding unit makes a collision decision depending upon output of an acceleration sensor which detects acceleration at a time of collision. The control unit controls generation of a starting signal based upon a difference between output of a decelerating direction integrating unit, which integrates the acceleration signal of the acceleration sensor in the decelerating direction, and output of accelerating direction integrating unit, which integrates the acceleration signal of the acceleration sensor in an acceleration direction. The trigger outputs the starting signal based on output of the collision deciding unit and output of the control unit.

Starting apparatus for passenger protecting apparatus

A vehicle height control system wherein vehicle height control is inhibited when the vehicle is turning and in a rolling state, the state when the control is inhibited being based upon the vehicle's speed from a speed sensor, the steering angular velocity of a steering wheel from a steering angle sensor and the outputs from sensors detecting the height of the vehicle body on both sides of the vehicle with respect to the wheels, which by the pattern of their outputs, represent that the vehicle is inclined from side-to-side and in the rolling state.

A suspension device for automobile performs changing-over of the damping force of a shock absorber and the spring constant of a suspension spring by an output from an acceleration sensor or an output from a road clearance sensor mounted on the vehicle body. The changing operation is not performed by magnitude of an output but is performed only when an output greater that a predetermined level continues for a predetermined time period to avoid unnecessary change-over operations of the suspension characteristic during cruising a rough road.

Suspension device for automobile

A suspension system for an automobile wherein after having been changed to a 'HARD' mode upon commencement of the turning movement, the characteristic of the suspension is not restored to the standard condition until completion of the turning movement is detected so that a stable running performance is obtained irrespective of the status of the curve of a road while good riding comfort at normal running is also maintained.

Automobile suspension system

In a suspension device for automobile having a shock absorber provided with a damping force change-over mechanism and a suspension spring provided with a spring constant change-over mechanism, a power source to perform both the changing-over of the damping force of the shock absorber and the spring constant of the suspension spring depends on a fluid pressure source equipped in the automobile and the fluid pressure from the pressure source is controlled by an electromagnetic valve.
