摘要:
In a human body detector, a wave-detection circuit for detecting waves of a resonance voltage is connected to a sensor resonance circuit that varies a constant frequency voltage in accordance with a change in the capacitance of a sensor electrode. The wave-detection circuit is connected to a differentiator that acquires a changing rate by differentiating the wave-detection voltage with respect to time, and allows a voltage to pass if the changing rate of the voltage is greater than or equal to a predetermined value. The differentiator is connected to a high-pass filter that allows passage of a voltage whose changing rate is greater than or equal to a second predetermined value. The high-pass filter is connected to a comparator whose non-inversion input terminal is connected to a power source that applies thereto a reference voltage.

摘要:
A vehicle door lock system has a lock mechanism for locking or unlocking the vehicle door. A control mechanism for controlling an operation of the lock mechanism includes first and second resonators. The first resonator resonates at a predetermined first value Q for transmitting a first signal to the outside of the vehicle. The second resonator is connected in series with the first resonator and resonates at a second value Q which is greater than the first value Q, and changing a resonant condition in accordance with a change of a capacitance. A single actuator is provided for actuating the first and second resonators. A switching mechanism is provided which utilizes the actuator for alternatively switching actuation between the first and the second resonators. The control mechanism controls the switching operation of the switching mechanism and the operation of the door lock mechanism in accordance with the resonant condition of the second resonator.

A door handle device for a vehicle is arranged in a door thereof. The door handle device includes a support member, door handle, lock detection electrode, and capacitance sensor. The door handle includes a first end, second end, pivot portion, and operation portion. A capacitance sensor detects issuance of a door lock command from a change in capacitance between an outer panel and lock detection electrode. The door handle includes a first handle case and second handle case covering the first handle case. The lock detection electrode is proximal to and faces an inner surface of at least one of an upper wall and lower wall of the second handle case. The lock detection includes an electrode end face facing the outer panel and formed to be non-planar.

摘要:
A control method for a door lock device performs an unlocking operation of a lock mechanism of a vehicle door by energizing and actuating an actuator in response to an unlocking command from a vehicle user. The method has: a first time period (T1) for energizing the actuator in accordance with the unlocking command by the user; a second time period (T2) for returning an operation portion provided on a vehicle from an operated position to a normal position; and a third time period (T3) during which the actuator starts the unlocking operation and complete the unlocking of the lock mechanism. The first time period is determined to be equal to or longer than a sum of the second time period and the third time period.
