Systems and methods for localization and passive entry/passive start (PEPS) systems for vehicles are provided. A communication gateway establishes a wireless communication link with a portable device. Sensors receive connection information about the wireless communication link that includes a channel map, a next channel for communication, a next channel time for communication, a parameter for calculating a subsequent channel, and (v) a channel hop interval indicating a time interval for communication. Each sensor receives communication packets sent from the portable device based on the connection information and measures signal information. A localization module determines a location of the portable device based on the signal information. A PEPS system performs a vehicle function including at least one of unlocking a door of the vehicle, unlocking a trunk of the vehicle, and allowing the vehicle to be started based on the location of the portable device.

A user identification system includes: a detection unit that detects prescribed motions of a person when the person boards or alights from a vehicle; an acquisition unit that acquires types of boarding information indicating that one of users boards or is on board the vehicle when one of the motions is detected; a memory that stores association information in which identification information of the users is associated with the types of boarding information corresponding to the users; a probability calculating unit configured to calculate a probability that each of the users boards or is on boarded the vehicle based on the types of boarding information and the association information; and an identification unit that identifies a user who boards or is on boarded the vehicle among the users based on the probability calculated by the probability calculating unit.

A car sharing system includes a car share device mounted on a vehicle. The car share device performs wireless communication with a mobile terminal, to which code information is registered so that the mobile terminal is actuated as a vehicle key of the vehicle, to authenticate the code information through the wireless communication. In an authentication completion state of the code information, the car share device performs ID verification through an electronic key system of the vehicle to allow the mobile terminal to operate an on-board device. The car sharing system further includes a position monitor that monitors whether the mobile terminal has approached the vehicle, and an automatic transmitter that automatically transmits an actuation permission request, which requests a permission for actuation of the on-board device, from the mobile terminal when the position monitor determines that the mobile terminal has approached the vehicle.

A vehicle with a device for passive authorization control is provided. The device features ultra-wideband antenna devices, by means of which the device with an electronic key for checking authorization for access is able to communicate activation of a function or the starting of the vehicle. At least one of the antenna devices features at least one reflector that is arranged at a distance from one ultra-wideband antenna of the antenna device.

A wireless communication system includes: an in-vehicle unit mounted on a vehicle and capable of wirelessly transmitting an access signal when an operation unit is operated; a portable device capable of wirelessly transmitting a vehicle-specific authentication code on a condition that the access signal is received; and a determination unit capable of determining whether or not the authentication code is a regular authentication code on a condition that the authentication code is received. Start of a driving source of the vehicle is permitted or running of the vehicle is enabled when the determination unit determines that the authentication code is the regular authentication code, and a security mode in which a function of transmitting the access signal by the in-vehicle unit or a function of transmitting the authentication code by the portable device is stopped can be set by a predetermined setting operation.

Systems and methods for secure communication between a vehicle and a portable communication device. One system includes a vehicle access system included in the vehicle. The vehicle access system is configured to wirelessly receive a shuffled message from the portable communication device, de-shuffle the shuffled message at a bit level to obtain a message, wherein de-shuffling the shuffled message at a bit level includes exchanging one bit at a first indexed position within the shuffled message with one bit at a second indexed position within the shuffled message, and initiate a vehicle operation based on the message.

Method and apparatus are disclosed for mobile device relay attack detection and power management for vehicles. An example vehicle includes a first module for first protocol communication, a second module for second protocol communication, and a controller. The controller is to determine a first distance to a mobile device utilizing a signal strength of the first protocol communication and determine, upon receiving an entry request, a second distance to the mobile device utilizing a time-of-flight of the second protocol communication. The controller also is to prevent entry when the second distance does not match the first distance.

A vehicle includes a keypad including a near-field communication (NFC) sensor, and a processor. The processor is programmed to operate in a normal mode of operation, in which remote keyless entry (RKE) or passive-entry passive-start (PEPS) functions are allowed; operate in a privacy mode of operation, in which the RKE or PEPS functions are disallowed; responsive to detection of an authorized access device via the NFC sensor while in the normal mode, and to receipt of a lock command within a predetermined time from the detection of the access device, transition from the normal mode to the privacy mode; and responsive to detection of the authorized access device via the NFC sensor while in the privacy mode, transition from the privacy mode to the normal mode.

A transceiver is configured to: pair with a mobile device; and transmit a predetermined signal from an antenna to the mobile device. A zone module is configured to: receive a signal from the mobile device in response to the predetermined signal; and based on the signal, select a zone within which the mobile device is present from a group consisting of: a first zone that is defined by a first radius from the antenna; a second zone that excludes the first zone and that is defined by a second radius from the antenna, where the second radius is greater than the first radius; and a third zone that is radially outward of the second zone and that excludes the first and second zones.

A platform for a programmable remote transmitter, designed, and programmed to perform single or multiple operations, optionally incorporated into a custom-made base that attaches to a smart phone case or other mobile devices. The remote transmitter is designed and activated via secured programming provided by an application on the user's mobile device, without the intervention of car dealers, locksmiths or using difficult manual processes. The remote transmitter can be attached to smart phones, mobile devices, or other suitable surfaces (e.g. a briefcase or a vehicle's dashboard) for safekeeping and accessibility.
