摘要:
A road surface detecting device has a rotary sensor for detecting the passage of teeth formed in an outer surface of a circular plate at regular intervals, which is connected to an axle of a vehicle and rotates thereabout, and generates an output signal pulsing every time when said teeth pass the rotary sensor. The output signal is inputted to a microcomputer. The microcomputer calculates period variations of the pulsing output signal and an average value of a predetermined number of the period variations. When the average value is not less than a predetermined value, the road surface is determined as being in a bad condition and when the average value is less than the predetermined value, the road surface is determined as being in a good condition; when the average value is less than the predetermined value and the most recently calculating period variation is not less than a predetermined period variation, the road surface is determined as being a rough area on a good road.

A vehicle seat comprising a horizontal seat cushion, a support shaft projecting upward from the seat cushion, and a rotatable backrest secured on the support shaft. The vehicle seat further comprises a mechanism for regulating the rotational movement of the backrest, which can be controlled in response to a detected driving state of the vehicle. The backrest may be immovably retained at a normal position relative to the seat cushion during the usual forward driving, and allowed to rotate to a suitable position during a stop, reverse, or cornering of the vehicle.

A plurality of electrical devices are controlled by a single operation switch. A transfer switch selectively connects the operation switch with one of the electrical devices. When a push button switch is actuated, the connection of the transfer switch is controlled so as to connect the operation switch with another of the electrical devices for a predetermined period of time.

In an apparatus for controlling an electromagnetic valve which is adapted for use with the fuel injection systems of internal combustion engines, after the expiration of a predetermined time the control of the energization of the electromagnetic coil of the electromagnetic valve is changed from constant-voltage control to constant-current control, and any surge voltage caused during the control change is selectively absorbed, thereby ensuring stable energization of the electromagnetic valve despite variations in the supply voltage or the like.

A switch is disposed between a power source and an activating element for activating a passenger protection apparatus. The switch detects a vehicle collision and closes its contacts to supply activating current to the activating element. A capacitor is connected in parallel with the activating element in order to charge momentarily when the switch closes. In this manner, it is possible to activate the activating element accurately because the activating element continues to be supplied with activating current by means of the charging voltage of the capacitor, even when the switch only closes for a time which is insufficient to activate the activating element.

An electronically controlled ignition system for internal combustion engines. Reference position detecting means generates reference signals and angular position detecting means generates angular signals indicative of the angular positions of an engine at every predetermined angle of its rotation. Computing means responsive to engine operating condition parameters computers a proper ignition coil energization starting timing data and a proper ignition coil de-energizing timing data. An ignition coil control circuit comprising latch circuits, comparator circuits and counting means converts the ignition coil energization starting timing data and the ignition coil de-energization timing data into pulses having a corresponding pulse width with respect to the rotational angle of the engine to supply an ignition coil energization starting timing signal and an ignition coil de-energizing timing signal to said ignition coil. The computations of the energization starting timing and de-energization timing are initiated in response to the reference signal and the energization starting timing signal, respectively, so that the energization starting timing data is computed by using the de-energization timing data computed in the preceding computation cycle and that the ignition coil control circuit is simplified in circuit construction.

A drive control device for a seat in a vehicle has a driver entry detection unit, a battery capacity detection unit, a seat drive unit, and a controlling circuit unit for generating a seat drive control signal. The controlling circuit unit has a function of deciding whether or not the capacity of the battery is lower than a predetermined reference value when an entry is detected by the entry detection unit, a function of prohibiting the driving of the seat when the decision of the battery capacity decision function is affirmative, and a function of effecting the driving of the seat when the decision of the battery capacity decision function is negative. The controlling circuit unit can provide a door opening degree monitoring function and a rear monitoring function.
摘要:
A device for moving up and down and tilting a headrest of a vehicle seat having a driven shaft for moving the headrest up and down and a support member for tilting the headrest. The drive shaft is operatively connected to leg members fixed to the headrest, and provided in a backrest of the vehicle seat. The support member is provided below the driven shaft. A drive mechanism drives the driven shaft to move the headrest up and down relative to the backrest, and a tilting mechanism rotates the leg members about the support member to tilt the headrest to a back of the seat backrest.
