A method is described for determining a position of a user device in relation to a vehicle, the vehicle including first and second receivers. The method includes transmitting a positioning signal by the transmitter of the user device, receiving the positioning signal by the first receiver and by the second receiver arranged at a distance from the first receiver, in at least one of the first and second receivers, receiving and identifying a reflected positioning signal reflected at a ground surface before reaching the first and second receivers, performing time synchronization between the transmitter and the first and second receiver, determining a position of the user device in a three-dimensional coordinate system based on a time-of-flight of the positioning signal received in the first and second receivers and on a time-of-flight of at least one reflected positioning signal received by at least one of the first and second receivers.

A keyless entry system for remotely controlling a door and a window of a vehicle includes: a remote control key that stores a plurality of function codes, selects a function code corresponding to an on-duration time of a lock switch or an on-duration time of an unlock switch, modulates the selected function code to a wireless signal, and transmits the wireless signal; and a receiving device that receives the wireless signal, demodulates the wireless signal into the function code, and outputs a door control signal or a window control signal according to the modulated function code, where the function code is divided into a basic function code field and a window function code field.

A transmitter device for coupling to a vehicle and for conducting a transmission to a remote system includes a transmitter and a processing circuit coupled to the transmitter and having an input interface. The input interface is coupled to an existing user interface of the vehicle for receiving an input to cause the transmitter to conduct its transmission to the remote system. The input interface is coupled to a vehicle sensor for receiving a vehicle sensor input including a motion status of the vehicle. The processing circuit is configured to prevent transmitter from conducting its transmission to the remote system unless the motion status of the vehicle indicates the vehicle is travelling at a speed less than a threshold speed.

A base control module for vehicles comprises, a controller which includes a housing, a programmable processor, on-board memory, and a plurality of inputs and outputs. The module also comprises, a set of pluggable module interfaces each comprising a standardized connector for any of a plurality of interchangeable pluggable modules, with each pluggable module having a different functionality, and each connector having a plurality of pins. A standardized communication protocol is provided between the base control module and any of the pluggable modules. Adaptable software on the base control module that can assign different configurations for the pins of the connector dependent upon the functionality of the pluggable module for those pins. The same base control module and set of pluggable module interfaces can be used for different pluggable modules.

An access control system is provided that enables a network operations center to manage and control access to a plurality of remote sites and to verify servicing of the remote sites. Individuals in possession of electronic programmable keys can be provided opening codes to activate their keys while in the field, and to enable the keys to access one or more electronic locks located at the remote sites. Usage information associated with the utilization of the electronic programmable keys at the remote sites is stored on the electronic programmable keys. A lock attendance code is generated by the keys to verify attendance at the remote locations. The lock attendance codes are then transmitted to the network operations center where they are decoded to verify servicing of the remote sites.

Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a seal device that includes a housing and a controller disposed inside the housing, with the controller including at least one sensor configured to measure motion data to detect motion of the seal device, and a communication module. The seal device further includes a seal connectable to the housing, with the seal including a shell and a conductive wire connectable to the controller. The controller is configured to cause the communication module to transmit at least one signal at least in response to one of, for example: a) determination, based on the motion data measured by the at least one sensor, of movement of the seal device, and/or b) detection of structural damage to the seal.

A vehicle control system includes a hatch opening control disposed at a vehicle and operable to open and close a hatch of the vehicle responsive to a triggering signal. The hatch includes one of a liftgate of the vehicle, a deck lid of the vehicle, a rear window of the vehicle and a rear door of the vehicle. A remote transmitter is operable to transmit the triggering signal responsive to a user input. The remote transmitter has at least two buttons. The user input includes one of (i) actuation of at least two buttons of the remote transmitter at the same time, (ii) repetitive actuation of one of the buttons at least three times with time gaps in between the actuations not exceeding a threshold time period, and (iii) actuation of at least two of the buttons in a predetermined actuation pattern.

The lock attendance codes are then transmitted to the network operations center where they are decoded to verify servicing of the remote sites.

Method and apparatus are disclosed for remote keyless entry authentication. An example remote keyless entry system includes a key fob and a vehicle. The key fob generates a secured message with a plaintext space and a ciphertext space. The vehicle (i) determines whether the key fob may be authorized based on first information in the plaintext space, (ii) decrypts an encrypted value in the ciphertext space based on a predicted full counter value, and (iii) determines whether the key fob is authorized based on second information in the encrypted value.
