摘要： A suspension control apparatus for an automotive vehicle has a plurality of suspension units which are disposed between each of the wheels of the vehicle and the vehicle body. An acceleration sensor measures the lateral acceleration of the vehicle body. A contol unit corrects the output of the acceleration sensor for drift of the neutral point of the sensor from a prescribed value. Based on the corrected output, the control unit controls the suspension units so as to suppress rolling of the vehicle body.

摘要： If a deceleration exeeds first set value G1 within set time T1 after the brake is depressed, a set amount of fluid is supplied to the fluid spring chamber of each front-wheel suspension unit. If a deceleration exceeds the second set value G2 when set time T1 or more has elapsed upon this operation, a set amount of fluid is exhausted from the fluid spring chamber of each rearwheel suspension unit. With this operation, since braking action for gradually increasing a deceleration is controlled by two stages, uncomfortableness which passangers feel in anti-nose-dive control can be greatly reduced. In addition, control is not performed only by depressing the brake pedal if an acutal deceleration is smaller than first set value G1. Even when a deceleration exceeds first set value G1 upon depression of the brake pedal, if the time when the deceleration exceeds first set value G1 exceeds set time T1, it is determined that a gradual braking operation is performed, so that only control for increasing a damping force is performed.

摘要： 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.

摘要： A flow velocity measuring apparatus includes a vortex-generating member disposed in the flow path and a temperature-resistance converting element positioned in contact with vortexes produced at the downstream side. A bridge circuit includes as one side the temperature-resistance converting element, and an amplifier circuit amplifies the output of the bridge circuit to provide a detection signal having a frequency corresponding to the periodic change in temperature of the element due to cooling action of the vortexes. A comparator provides one of a high level or a low level at the input end of the amplifier circuit to keep the temperature-resistance converting element at a first temperature when the level of the detection signal is lower than a prescribed preset value and provides the other of a high level or a low level at the input of the amplifier circuit to maintain the element at a second temperature higher than the first temperature when the level of the detection signal is higher than the prescribed preset value.

摘要： An air flow rate measuring device for use with an internal combustion engine in which a signal accurately representing the air flow rate of intake air in an intake air passage of the engine is always available. A first, frequency signal is generated which has a frequency which varies in proportion to frequency of vortices in a vortex stream in the intake air passage. An analog signal is provided which has an amplitude which varies in accordance with an average of the air flow rate in the intake air passage. By using these signals together, an accurate indication of the air flow rate in the intake air passage is continuously provided.
