A vehicle door latch device comprises an outside lever, a locking lever, a holding member, an opening link and a spring. The spring applies an urging force, smaller than an elastic holding force of the holding member in an unlocking direction, to the opening link. A coil is held in a holding recess of a rotation central portion of the opening link. The first arm engages with the outside lever, and the second arm engages with the opening link. If a panic state occurs, the locking lever can rotate to an unlock position, and the opening link returns to an initial position before a releasing action and is moved to the unlock position by the urging force of the spring.

A method of controlling a vehicle includes sensing movement of an interior door handle, sensing a position of a vehicle door after movement of the interior door handle is sensed to determine if the door remains in an unopened position or if the door moves into an opened position after movement of the interior door handle is sensed. When movement of the interior door handle is sensed, a timer is started to determine if the measured time period is equal to or greater than a maximum delay time. A active or inactive state of a double door lock feature of the door lock system is determined and a control signal to automatically generated to deactivate the double door lock feature if the double door lock feature is active, the measured time period is equal to or greater than the maximum delay time, and the door is in the unopened position.

Methods and systems for autonomously closing an open door of a vehicle are disclosed. A door closing system for a vehicle includes a sensor system and an autonomous driving system. The sensor system determines if a door of the vehicle is open and determines if a surrounding of the vehicle is free of obstacles in a predetermined range. The autonomous driving system instructs the vehicle to move if a door of the vehicle is open and if the predetermined range of the surrounding of the vehicle is free of obstacles, such that the door is closed as a result of the movement of the vehicle.

An authentication system includes at least one portable device and an authentication device. The at least one portable device includes a measurement unit configured to measure a signal intensity value in communicating with an authentication device, prior to registering of an authentication ID of the portable device by the authentication device, and an ID transmitting unit configured to transmit, to the authentication device, the authentication ID at a transmission timing depending on the signal intensity value measured by the measurement unit. The authentication device includes a receiving unit configured to receive the authentication ID transmitted by the portable device, a determination unit configured to select, as a target authentication ID, the authentication ID transmitted at a predetermined timing by the portable device, among at least one authentication ID received by the receiving unit, and a registration unit configured to register the target authentication ID selected by the determination unit.

An operation input detection device includes an operation input detection unit, a change amount accumulation unit, a section variation amount calculating unit, and a noise determination unit. The operation input detection unit detects an operation input on an operation input unit based on a sensor output of a capacitance sensor. The change amount accumulation unit accumulates a change amount of the sensor output in a determination section. The change amount of the sensor output is a difference of a detection value of the sensor output detected as each sampling timing from a previous value of the sensor output. The section variation amount calculating unit calculates a section variation amount of the sensor output.

A vehicle sliding door and sliding door closure system therefor equipped with electrically actuatable component(s) that eliminate one or more of the mechanically actuatable component(s) of currently known vehicle sliding doors and sliding door closure systems.

An opening control device including a case, a handle movably mounted between at least a flush position in which the handle is entirely or partially housed within the case and an ejected position in which the handle is at least partially emerged from the case. The opening control device includes a mechanism configured to be mechanically triggered in response to a push-in action into the case of the handle, the completion of the push-in action being adapted to cause the triggering of the mechanism. Furthermore, the mechanism is configured to automatically drive in movement the handle over all or part of a stroke starting from a pushed position of the handle to the flush position through the ejected position.
