An access system for a vehicle includes a receiver and an access module. The receiver is configured to receive a signal transmitted from a portable access device to the vehicle. The access module is configured to: generate a differentiated signal based on the received signal; up-sample the differentiated signal to generate a first up-sampled signal; obtain or generate an expected signal; up-sample the expected signal to generate a second up-sampled signal; cross-correlate the first up-sampled signal and the second up-sampled signal to generate a cross-correlation signal; based on the cross-correlation signal, determine a phase difference between the first up-sampled signal and the second up-sampled signal; determine a round trip time of the signal received by the receiver; and permit access to the vehicle based on the round trip time.

Upon autonomous travel control of a subject vehicle having an autonomous travel control function based on a remote operation command from a remote operation device located outside the subject vehicle, when start of a remote operation by the remote operation device is input, a predetermined authentication code stored in the subject vehicle is displayed inside or outside the vehicle so as to be visible, the displayed authentication code is acquired by the remote operation device, a determination is made whether or not the authentication code acquired by the remote operation device matches the authentication code stored in the vehicle, and upon matching, a paring process between the vehicle and the remote operation device is completed.

An ordering management system for a property includes: a location module configured to determine locations of mobile devices that are located within boundaries of the property; a selection module configured to, in response to receipt of an order from a first mobile device for delivery of one or more items to a location of the first mobile device within the boundaries of the property: select one vendor at the property to supply the item(s) of the order; determine a group of the mobile devices based on the location of the first mobile device; and select a second mobile device from the group; a device communication module configured to selectively transmit, to the second mobile device, the location of the selected one vendor and the location of the first mobile device; and a vendor communication module configured to selectively transmit the order to the selected one vendor.

A device may receive an arming signal associated with immobilizing a vehicle. The device may monitor, based on receiving the arming signal, a current associated with an electrical power output from a battery of the vehicle. The device may detect that a measurement of the current satisfies a threshold associated with an ignition component starting an engine of the vehicle. The device may control, based on detecting that the current satisfies the threshold, a bypass circuit to reduce the electrical power output to prevent the ignition component from starting the engine.

The invention relates to a method for securing a command to be applied to a motor vehicle, characterized in that said method comprises: a first step of generating first data, via a vehicle electronic control unit; a second step of sending said first data to a mobile terminal comprising a screen, via the electronic control unit; a third step of displaying the first data on the screen of the mobile terminal; a fourth step in which a human user processes the first data in order to obtain second data; a fifth step of sending the second data to the electronic control unit via the mobile terminal; a sixth step of comparing said second data to a key of the first data, via the electronic control unit; if the second data is validated by the key of the first data, a seventh step of activating the motor vehicle via the electronic control unit, in order to implement at least part of the control.

A system and method of providing status updates to one or more mobile devices. The method includes receiving a vehicle action request from the mobile device at a central office, determining a status update frequency based upon at least one real-time characteristic, and instructing the mobile device to request status updates on the vehicle action request to the central office at the status update frequency. In an alternative method, a plurality of mobile devices may be instructed to use different status update frequencies. The system includes a server configured to receive a vehicle action request from the mobile device at a central office, determine a status update frequency based upon at least one real-time characteristic, and instruct the mobile device to request status updates on the vehicle action request to the central office at the status update frequency.

A keyless entry and start system for a vehicle includes a vehicle subsystem configured to control at least one of access to an interior compartment of the vehicle and starting of the vehicle. The system further includes an actuator movable between first and second positions and a switch coupled to the actuator. The switch assumes a first state when the actuator is in the first position and a second state when the actuator is in the second position. The system further includes a controller coupled to the switch and configured to detect an actuation sequence of the actuator, the actuation sequence corresponding to an access code. The controller is further configured to compare the access code to an authorization code and generate a control signal configured to cause the vehicle subsystem to switch states when the entry code corresponds to the authorization code.

A system and method for remote control of functionalities of a vehicle, for example a motor vehicle reserved for hire, is provided. The system and method include transmission and receipt of information between a mobile terminal, a remote vehicle management system and a control unit of a vehicle to remotely control, particularly to remotely initiate, particular functionalities of a vehicle which has been selected, particularly reserved, in advance using the vehicle management system. The mobile terminal is identified to the vehicle on the basis of an interchange of identifiers that the vehicle and the terminal have received in advance from the vehicle management system.

A vehicle electronic key system includes a plurality of in-vehicle communication devices and an authentication device. Each of the plurality of in-vehicle communication devices communicates wirelessly with another in-vehicle communication device, and based on a signal transmitted from the another in-vehicle communication device, generate distance-related information that directly or indirectly indicates a distance to the another in-vehicle communication device. The authentication device specify a plurality of inter-communication device distances based on the distance-related information generated by the plurality of in-vehicle communication devices, and does not execute a vehicle control when at least one of the plurality of inter-communication device distances deviates from a predetermined normal range.

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.
