A remote control lock system for a vehicle has a coder of the transmitter and the decoder of the receiver designed to receive either a radio frequency or light frequency oscillator and detector, respectively, so that for a given coding system, different modes of wave transmission between the receiver and the transmitter can be effected.

A safety system used in combination with a vehicular power door latch has a mechanism operated by a motor in turn driven by a drive apparatus for opening and closing vehicle door. The safety system comprises a vehicle speed sensor generating an output when vehicle speed exceeds a predetermined limit, a counter startable when the motor is actuated, and a controller connected between the speed sensor and the counter and to the apparatus for shutting down the apparatus and thereby deenergizing the motor when the vehicle-speed output exceeds the limit and when the counter has counted since the motor started beyond a predetermined limit.

An electrical control system for a vehicle having electrically operated locks provides at each door an emergency unit built into the respective lock and having a power storage unit continuously connected between the starter battery and the motor driver for the lock, and a voltage limiter reducing the voltage applied to the storage unit and the motor driver from that of the storage battery.

A vehicle lock system has individual door locks each having an actuator provided with a printed circuit board on which a microcontroller, motor driver of the lock actuator, and a multiplexing element are encapsulated, the printed circuit board being mounted in the housing of the respective lock and being connected by the multiplexing element to a single-line data bus for binary communication with the individual lock from the central station.

A motor-vehicle door latch for securing a door to a doorpost has a support mounted on a doorpost, a bolt projecting from the support, and a latch fork pivoted on the door, including a switch-actuating part, and movable between an engaged position interfitting with the bolt and retaining the door in a closed position fixed relative to the doorpost and a disengaged position out of engagement with the bolt and permitting the door to move relative to the doorpost. A switch on the support detects the position of the switch-actuating part and generates a door-closed output when the fork is in the engaged position and a door-open output when the fork is in the disengaged position.

A motor-vehicle door latch has a drive having a housing formed with an inner surface formed relative to a main axis traversing the housing with two angularly offset and radially inwardly open notches, a shaft rotatable in the housing about the main axis and having a radially outwardly projecting bump, and a wheel rotatable in the housing about the main axis, surrounding the shaft in the housing, and connected to the input member of the latch to rotate jointly with the input member between locked and unlocked positions of the latch. A lobe on the wheel projects radially outward into one of the notches. A radially outwardly deflectable abutment on the wheel is angularly engageable with the bump of the shaft and is urged by a spring radially inward on the wheel so that the bump can angularly engage the abutment and angularly displace the wheel. A rocker pivotal on the wheel about a rocker axis generally parallel to the main axis and angularly offset from the abutment has an end offset angularly from the rocker axis and formed with an outwardly directed tooth engageable in the other notch only in the locked position of the wheel. The bump and an inner surface of the rocker are dimensioned such that, when the wheel is in the locked position, engagement of the bump with the end of the rocker forces the tooth radially outward into the other notch and thereby angularly blocks the wheel in the housing.

A power actuator used with a door latch has a housing fixed adjacent the latch and a slide linked to the latch and displaceable along an axis in the housing between locked and unlocked positions respectively corresponding to the locked and unlocked conditions of the latch. This slide is formed with a radially elastically deflectable entrainment formation and with a crosspiece. An axial spindle carries a nut engageable with the entrainment formation and the crosspiece of the slide. A radially elastically deflectable locking dog axially fixed to the slide is also engageable with the nut and the housing is formed with a radially inwardly open recess in which the dog is engageable only in the locked position of the slide. An electric motor can rotate the spindle and thereby displace the nut from an antitheft end position through an intermediate position and into an end locked position. In the antitheft position the nut engages the crosspiece and the dog, presses the dog into the recess, and positively retains the slide in the locked position. In the intermediate position the nut engages the entrainment formation of the nut in the locked position of the slide and out of engagement with the dog. In the end locked position the nut engages the entrainment formation of the nut in the unlocked position of the slide. The slide is displaceable between its unlocked and locked positions in the unlocked end position of the nut by elastic deflection of the entrainment formation.
