    摘要: First and second sample-hold circuits sample and hold the atmospheric pressure alternately every time when a vehicle travels a predetermined distance. A signal representing a difference between the holding values of the first and second sample-hold circuits, that is, a signal representing a slope of the road on which the vehicle is travelling is displayed through a latch circuit.

    摘要: A novel constant-speed drive system for automotive vehicles is disclosed, in which in response to an instruction for constant-speed drive while the vehicle is under acceleration, it is decided whether the vehicle acceleration at that particular time is higher than a predetermined value, and in accordance with the result of this decision, the change rate of the opening of the throttle valve is determined by use of an equation in which the value of a factor is set accordingly. In the case where the acceleration is comparatively high, the value of the factor may be changed to improve the responsiveness of the change rate of the opening of the throttle valve with the change in vehicle speed, thus making it possible to fully prevent the overshoot of the running vehicle speed.

    摘要: A demagnetizer for removing residual magnetism in vehicles includes a single coil which is adapted to surround a portion or the whole of the body of a vehicle. A direct current and alternating current are supplied to the single coil simultaneously to produce a d.c. magnetic field and an a.c. magnetic field. The direction and magnitude of the d.c. magnetic field are so arranged, that the d.c. magnetic field cancels the external magnetic field. The magnitude of the a.c. magnetic field is varied within a predetermined range periodically to remove the residual magnetism.

    摘要: A demagnetizing apparatus for removing residual magnetism in the body of an automobile which is equipped with a magnetic bearing indicator. A first and a second coil are wound around a substantially flat frame of a non-magnetic material to produce respectively a fixed d.c. magnetic field and a controllable a.c. magnetic field in orthogonal directions with each other and along flat surfaces of the substantially flat frame. The substantially flat frame with coils is positioned adjacent to but spaced from a body portion such as a roof, door or floor of the automobile, so that the d.c. magnetic field produced by the first coil cancel the external magnetic field caused by the terrestrial magnetism. The a.c. magnetic field is controlled to be intensified and weakened alternately thereby to remove the residual magnetism of the body portion without being influenced by the external magnetic field.

    摘要: In a speed control system for vehicles, a speed difference calculation circuit calculates an absolute value of a time difference between a predetermined period of time corresponding with a desired speed and an instant period of time corresponding with the actual speed, an acceleration calculation circuit calculates an absolute value of a time difference between the respective instant periods of time, and a correction signal generator calculates a sum of the absolute values in consideration with the actual speed when each sign of the calculated time differences is positive or negative and calculates a difference between the absolute values in consideration with the actual speed when respective signs of the calculated time differences are opposite to each other. The signal generator selectively produces correction signals related to the calculated sum and the calculated difference. A distribution circuit produces a control signal in response to the respective correction signals, and an actuator controls the opening angle of the engine throttle in response to the control signal.

    摘要: A system for warning the driver of an acceleration or deceleration of a vehicle. A wheel sensor detects wheel rotational speeds N.sub.i and N.sub.i + 1 during two predetermined time intervals T.sub.i and T.sub.i + 1. The absolute value of the difference .vertline.N.sub.i - N.sub.i + 1 .vertline. between the rotational speeds is computed by a computing circuit. Indicating means gives an indication of acceleration when the difference is greater than a predetermined value and when the speed difference is negative, whereas an indication of deceleration is given when the speed difference is positive.
