A door opening and closing device includes: a door opening and closing drive unit capable of opening and closing a door with respect to a vehicle body; a detection unit configured to detect a plurality of detection objects around the door; a memory part configured to store a detection result of the plurality of detection objects which are detected by the detection unit; and a control unit configured to perform an open/close control of the door by way of the door opening and closing drive unit. The control unit performs an open/close control of the door based on a detection result of the detection unit and a plurality of stored information stored in the memory part.

One general aspect includes a method of activating vehicle operations, the method including: (a) receiving, via a controller, a sequence of input signals from a plurality of device interfaces to define an activation attempt, where each device interface is configured to control operation of a corresponding vehicle aspect; (b) determining, via the controller, if the activation attempt matches an activation sequence key; and (c) activating vehicle operations, via the controller, when it is determined the activation attempt matches the activation sequence key.

Provided is an apparatus for sensing a remaining passenger in a vehicle and generating an alarm. The apparatus includes a first sensor unit provided on the ceiling of the inside of the vehicle and configured to sense presence or absence of a remaining passenger per seat when a door of a driver's seat is open in an engine off or on state, and a controller configured to generate an alarm when there is a remaining passenger in a seat other than the driver's seat when the engine is turned off and to determine whether the door of the driver's seat is closed and generate an alarm when the first sensor unit senses exit of a driver and presence of a remaining passenger.

A vehicle security system includes a main printed circuit board (PCB) assembly, a radio frequency identification (RFID) assembly, a starter assembly, and an RFID tag. The main PCB assembly may be configured to determine whether an activation sequence of a motor vehicle is correct, whether an RFID tag is in close physical proximity to the RFID reader, and whether the RFID tag is a valid RFID tag. The main PCB assembly may transition the vehicle security system into a disarmed state to allow the starter assembly to start the motor vehicle in response to determining that the RFID tag is valid. The main PCB assembly may deactivate a critical component of the motor vehicle in response to determining that the activation sequence is not correct, that that the RFID tag is not in close physical proximity, or that that the RFID tag is not valid.

When an autonomous driving vehicle picks a user up, a control device performs departure condition confirmation processing. The departure condition confirmation processing includes first authentication processing that performs authentication of the user outside the autonomous driving vehicle based on first authentication information, door lock release processing that releases a door lock in response to the completion of the first authentication processing, second authentication information provision processing that makes the user acquire second authentication information different from the first authentication information in response to the completion of the first authentication processing, second authentication processing that performs authentication of the user inside a vehicle cabin of the autonomous driving vehicle based on the second authentication information, and start permission processing that permits the start of the autonomous driving vehicle in a case where the second authentication processing is completed.

An antenna driving apparatus includes: a direct current power source supplying direct current power to a human detecting IC detecting contact to a human detecting area by a user, the power source outputting a power source voltage to a first connecting line connected to a power source terminal of the IC and outputting a reference potential to a second connecting line connected to a GND terminal of the IC; an antenna driving circuit driving an antenna transmitting a signal to a portable device, the antenna driving circuit outputting a first antenna drive signal to the first connecting line and outputting an antenna drive signal; and a control unit performing switching control of the power source voltage and the antenna drive signal to be output to the first and second connecting lines and switching control of the antenna driving circuit.

A vehicle control device includes a processor including hardware, the processor being configured to: stop a smart key function of a vehicle when a first state in which an intensity of a radio wave received from a predetermined wireless communication device is a threshold or more has continued for a predetermined time.

The disclosure relates to a method to lock, unlock and start a vehicle without using a radio key or electronic vehicle key. According to the disclosure, the function of starting the vehicle without actively using the key is blocked when the vehicle is locked. When the vehicle is unlocked in a manner secured against relay station attacks, the possibility exists of starting the vehicle without actively using the key.
