A method is proposed for calibrating a position detection of a portable key element by an access control system for a motor vehicle. The access control system comprises a detection device which is configured to detect a position of the key element relative to the motor vehicle by means of radio. The method comprises generating a first trigger signal when the key element is located in a first position relative to the motor vehicle and detecting a first signal strength in response to the first trigger signal. The method determines a correlation of signal strength and distance of the key element relative to the motor vehicle depending on the first signal strength at the first position. Furthermore, an access control system for a motor vehicle is proposed.

A method for a secure Passive Entry Passive Start (PEPS) authentication protocol measures the walking gait of a user approaching a related vehicle using a passive key device carried by the user. The method also includes measuring the user's gait from the perspective of the vehicle using a vehicle perception system to compare the two and validate the security of an unlock request, authenticate the unlocking session, and protect against relay attacks. The two-factor authentication protocol validates the physical presence and temporal state of the key fob or mobile phone relative to the vehicle using detected key gait measurement (key G-gait) and a vehicle perception-based gait (C-gait) measurement by comparing the independent gaits and generating control commands responsive to consistent and inconsistent measurements.

The present disclosure relates to methods and associated systems for unlocking a vehicle. The vehicle has a first input device and a second input device. The method includes (1) receiving a passcode from the first input device; (2) receiving a confirmation of the passcode from the second input device; and (3) in response to the confirmation, storing the passcode in a storage device associated with the vehicle. The passcode is input by operating the first input device in a first predetermined way, and, the confirmation is input by operating the second input device in a second predetermined way.

A vehicular exterior door handle assembly includes a base portion configured to mount at an exterior door handle region of a vehicular door of a vehicle, a handle portion, and a sensing module that includes at least one light emitter and at least one light sensor. With the base portion of the vehicular exterior door handle assembly mounted at the exterior door handle region of the vehicular door, the light emitter, when energized, emits light. With the base portion mounted at the exterior door handle region of the vehicular door, and with the light emitter energized, the light sensor senses light emitted by the light emitter. Responsive to light sensed by the light sensor with the light emitter energized being below a threshold level, the sensing module determines a presence of a person's hand at the handle portion.

A method for remotely controlling a system of key related functions of a vehicle, the system is connectable with a remote unit over a communication network, is capable of transferring audio data. The method includes receiving at the vehicle over the communication network a sequence for the system wherein the sequence comprises a first sound sequence, and performing a key related function in the system in response to receiving the sequence.

The invention relates to a device (10) for a vehicle (1) for detecting an activation action in a detection region (51), and in particular for mounting on a vehicle part (5), in order to activate a function of the vehicle (1) depending on the detection, comprising: a multi-layer printed circuit board (20), at least one electrically conductive sensor element (31) for capacitive sensing in the detection region (51), wherein the sensor element (31) is arranged on the printed circuit board (20), at least two shielding elements (40) for shielding (41) for the sensing.

An opening and closing body control device is applied to a vehicle that includes a vehicle body having an opening, an opening and closing body configured to open and close the opening, a drive unit configured to operate the opening and closing body, and a detection device configured to detect a gesture operation of a user. The opening and closing body control device includes: a position acquisition unit configured to acquire a position of a portable device carried by the user by wireless communication; an operation determination unit configured to determine whether the gesture operation is executed in a situation where the portable device is present in a detection area of the detection device; and an opening and closing body control unit configured to operate the opening and closing body based on a content of the gesture operation when it is determined that the user executes the gesture operation.

A mobile device is carried by a person to be authenticated. An acceleration sensor is installed in the mobile device and configured to output an acceleration signal corresponding to acceleration applied to the mobile device. A processing device is configured to execute determination processing for determining whether the person is walking based on the acceleration signal. A control device is configured to control operation of a controlled device based on a result of the determination processing and a result of processing for authenticating, by way of the mobile device, the person as a user of the controlled device. The control of the controlled device based on the authentication processing is disabled from time when the determination processing is initiated by the processing device until when a determination as to whether the person is walking is initially made.

A computing device can be programmed to, upon determining that a location of a vehicle is within a set of boundaries associated with a wireless network and that a user device is authenticated to the network, authorize the user device to control the vehicle. The computing device can be further programmed to, upon determining that the vehicle is not within the boundaries, authorize the user device to control the vehicle based on transmitting an authentication credential to a server and receiving an authorization certificate.

An unauthorized communication establishment prevention system includes a measurement unit arranged in at least one of a terminal and a communication peer. The measurement unit implements an unauthorized communication detection function and obtains a measurement value corresponding to a distance between the terminal and the communication peer. The system further includes a process execution unit that controls initiation, based on a determination result of whether the measurement value is appropriate, of an authentication performed through wireless communication established between the terminal and the communication peer even when the terminal is not operated. The system further includes a monitoring unit that monitors a battery level of the terminal and a suspension unit that suspends the unauthorized communication detection function when the battery level of the terminal is less than a specified amount that is not a battery depletion level.
