Abstract: An automotive vehicle has a body provided with a passenger compartment and a luggage compartment. Doors, which close the passenger compartment, carry latches which engage the body to secure those doors. While the doors have exterior handles which are connected to the latches to release the latches, at least when the latches are set to an unlocked condition, each latch may be shifted to a locked condition in which the exterior handle for its door will not release it. Each door also carries an electrical actuator which is coupled to the latch of the door to shift that latch between its locked and unlocked conditions. Two of the doors carry switches which are accessible from the passenger compartment and when operated will cause electrical actuator to shift the latches in unison to their locked or unlocked conditions, depending on the manner in which the switch is manipulated.

Abstract: The disclosure is concerned with an electrically operable central locking and unlocking device for vehicle doors with mechanical locks at each door or lid, and with electromechanical actuation for such door locks in which the actuation is transferred by a vertically movable actuating rod capable of moving between an unlocked position and a locked position, to a control rod of the associated door lock. The device includes a reversible electric motor, a transmission, and an actuating mechanism for the actuating rod. The device also includes exterior ridges on a spindle-nut and projecting formations which serve to carry along the actuating rod during the lock stroke and during the unlocking stroke. The ridges can override, after completion of the lock stroke, as well as after completion of the unlock stroke, the projecting formations.

Abstract: A solenoid activated locking system primarily for hood and trunk manual release systems for vehicles. The solenoid is connected to a cable tied to the latch of a conventional hood or trunk release system. Unless activated, the solenoid prevents manual release of the trunk or hood lids to prevent access to the truck or engine compartment to someone who has obtained unauthorized access to the vehicle interior. The solenoid is automatically actuated for a preselected period of time whenever the ignition is turned on or off or when a reset switch is closed for more than a minimum and less than a maximum period of time. In addition, the solenoid is activated automatically during closure of the hood or trunk lid to permit secure engagement of the corresponding latch mechanism. An emergency release cable, hidden in an obscure location external of the vehicle, is provided for enabling manual release of the solenoid in the event of vehicle battery failure or other otherwise disabling event.

Abstract: A keyless entry system for an automotive vehicle allows operation of a vehicle device or devices without the need for an ignition key or other mechanical keys. A user can simply depress a single push-button or operate another suitable type of switch to activate the system and operate the desired vehicle device to the desired position. The system generally comprises a pocket-portable radio signal transmitter and a controller mounted on the vehicle and associated with the vehicle device. The transmitter has a small, long-life battery and the controller receives electric power from the vehicle battery. Power conservation for both the transmitter and the controller is achieved by activating them for limited periods in response to operation of the manual switch.

Abstract: A keyless entry system allows operation of various vehicle devices including a door lock without using a mechanical key, such as an ignition key. The system comprises a wireless, portable transmitter adapted to produce a radio signal indicative of a unique code preset in the transmitter, and a controller mounted on the vehicle and associated with the vehicle devices. The controller has a preset code to compare with the unique code indicative in the radio signal transmitted from the transmitter. The controller also detects impending or accomplished locking of the transmitter in the vehicle and produces an alarm and subsequently disables the keyless entry system unless the transmitter is removed from the vehicle within a given period of time after the alarm is given.

Abstract: A keyless entry system can lock and unlock an automotive vehicle door, a trunk lid, a glove box and/or a steering column without an ignition key. The system comprises a transmitter producing a radio signal indicative of a preset unique code, and a controller receiving the radio signal and performing desired locking or unlocking operation when the code from the transmitter matches a preset code. A manual switch is provided to order the transmitter to transmit the code-indicative radio signal to the controller. The transmitter encloses a battery acting as a power source. Locking the transmitter in the vehicle is detected by detecting that the code signal level remains substantially unchanged for a given period of time after the vehicle is locked. In such cases, an alarm is produced to remind the driver to remove the transmitter from the vehicle cabin by operating the manual switch to open the door.

Abstract: When a driver inserts a key into a cylindrical lock-type outside door switch and rotates it clockwise or counterclockwise, a slide door for an automotive vehicle is opened or closed automatically by motor power from the outside of the vehicle. Additionally, when the driver inserts the key into the outside door switch, and rotates it to an open position, the slide door is unlocked automatically before being opened; when the driver extracts the key from the outside door switch, the closed slide door is locked automatically. A motor is mounted on the slide door and a power supply is applied to the motor by means of a current collector. A pinion and rack are also mounted on the slide door to open or close the door. Such structure allows the slide door to be opened or closed manually or automatically.
