A vehicle theft-prevention apparatus can include a locking mechanism configured to engage to secure the vehicle theft-prevention apparatus into a vehicle and disengage to unsecure the vehicle theft-prevention apparatus from the vehicle. The vehicle theft-prevention apparatus can include a clutch mechanism configured to prevent the locking mechanism from further engaging based on a magnitude of force applied. The clutch mechanism can include a first portion configured to rotate about an axis and comprising at least one aperture, a second portion configured to rotate about the axis and comprising a track, and at least one article configured to pass through the at least one aperture and travel along the track.

A vehicle theft-prevention apparatus can a motor unit configured to rotate based on an electrical signal. A shaft of the motor unit can be coupled to a cam. The cam can move a connection plate between an engaged position and a disengaged position. When the connection plate is in the engaged position, a locking mechanism can move between a locked position and an unlocked position. When the connection plate is in the disengaged position, the locking mechanism can maintain a current position.

A vehicle theft-prevention apparatus can include a slip clutch mechanism, a locking mechanism, and a cylindrical body including a first portion and a second portion. The first portion can be configured to rotate about the second portion. The locking mechanism can be configured to engage based on rotation of the first portion relative to the second portion in a first direction, and disengage based on a rotation of the first portion relative to the second portion in a second direction. The slip clutch mechanism can be configured to prevent the locking mechanism from further engaging from rotation in the first direction relative to the second portion based on a magnitude of force applied.

A method performed by a vehicle system for handling parameters associated with surroundings of a vehicle. The vehicle system obtains information indicating a first parameter associated with the surroundings of the vehicle and sensed by at least one low power sensor. The low power sensor is associated with the vehicle. The vehicle system triggers startup of at least one high power sensor when the first parameter has fulfilled a criteria. The high power sensor consumes a larger amount of power than the low power sensor, and the high power sensor is associated with the vehicle or another vehicle. The vehicle system obtains information indicating at least a second parameter associated with the surroundings of the vehicle and sensed by the high power sensor.

A method and apparatus for determining a propagation delay and/or a distance between a plurality of transceivers, in particular between transceivers outside and/or as part of a motor vehicle, wherein the transceivers are each designed: to generate identical codes in a plurality of these transceivers, using a calculation method known to them, from at least one starting value transmitted, in particular, from one of the transceivers to the further transceivers, to transmit one or more messages from at least one of the transceivers to one or more further ones of the transceivers, which messages each contain at least one of the codes, to determine at least one propagation delay and/or at least one distance between at least two of the transceivers, in particular from the propagation delay and/or transmission times of the one or more messages.

The invention relates to a method for operating a transmitter unit (12) of a wireless key system of a motor vehicle (10), wherein a control device (16) of the transmitter unit (12) provides that, for a respective closing operation (S) in at least one measurement cycle (14), in each case in response to a polling message (15), in a plurality of successive time slots (19), in each case one of a plurality of anchor transmitters (13) of the transmitter unit (12) transmits an anchor message (17), and the measurement cycle (14) is ended by reception of a final message (18), which signals reception times of the anchor messages (17) measured by a wireless key unit (11). The invention provides that, for determining a transmission sequence (22) of the anchor transmitters (13), by means of an assignment rule (20) an assignment (21) of the anchor transmitters (13) to the time slots (19) is carried out, wherein the assignment rule (20) provides that the assignment (21) takes place variably over time.

A server device includes a processor configured to i) acquire vehicle information when a delivery request is made; ii) acquire predetermined authentication information for unlocking and locking a door of a vehicle, based on the acquired vehicle information; iii) transmit the acquired predetermined authentication information to a delivery terminal; and iv) to acquire predetermined proof information for proving that a user of the vehicle is a rightful recipient of a delivery article, by communicating with a user terminal. The processor is configured to transmit the acquired predetermined authentication information to the delivery terminal, on a condition that the predetermined proof information is acquired.

A vehicle electronic key system acquires a vehicle vibration, which is a vibration generated in a vehicle, at a time of a driver's door of the vehicle being closed after a driver is presumed to get in the vehicle, and a key vibration, which is a vibration generated in an electronic key, at the time of the driver's door being closed after the driver is presumed to get in the vehicle. The system determines whether or not the vehicle vibration and the key vibration at the time of the driver's door being closed match each other, and permits an operation of a predetermined operation target device mounted in the vehicle on the condition that the vehicle vibration and the key vibration match each other.

An authentication information providing server includes: a memory configured to store information about vehicles associated with a recipient of a package as a place of delivery, and store pieces of authentication information corresponding to lock/unlock devices each configured to lock or unlock a corresponding one of predetermined compartments of the vehicles; and a processor configured to issue the authentication information to a delivery user terminal based on a request from the delivery user terminal, the delivery user terminal being used by a user who delivers the package, and, when there is a request from the delivery user terminal to set a place of delivery of the package to a vehicle different from a first one of the vehicles, corresponding to the authentication information issued first by the processor, issue the authentication information corresponding to a second one of the vehicles, different from the first one.
