A portable electronic device to be used as a keyless device of a vehicle includes a controlling circuit which includes a physiological feature detection module and a processing circuit. The physiological feature detection module is used for detecting a physiological feature of a person. The processing circuit is coupled to the physiological feature detection module and used for determining whether the person is an authorized user of the vehicle according to the detected physiological feature of the person, and for opening a car door of the vehicle or starting the vehicle when the person is identified by the processing circuit as the authorized user.

A sensor is configured to receive connection information from a portable device via a communication gateway in a vehicle and to communicate with a portable device using impulse radio (IR) ultra-wide band (UWB) communication based on the connection information. A location of the portable device is determined based on ranging using IR UWB communication.

A remote control system for a marine vessel includes at least one fob and a configuration control system configured to detect available devices on the marine vessel to be controlled remotely for the marine vessel, generate a list of available functions for at least one user-selectable fob command based on the detected available devices, present the list of available functions to the user via a fob configuration user interface such that the user can select one or more functions in the list of available functions, identify a system command associated with each selected function so as to configure a set of system commands based on the user-selected functions, and store the user-configured set of system commands in association with the fob identification and the selected fob command. The system further includes a helm transceiver module to effectuate activation/deactivation of the available devices based on the user-configured set of system commands.

In a case where a non-history position start for starting an engine based on a remote operation at a position at which a position of a vehicle is different from a start history position having a start history of the engine is executed, a limitation condition for limiting an engine start is tightened as compared to a case where a history position start for starting the engine based on the remote operation at the start history position is executed. That is, in a case where the non-history position start is executed, it is difficult to start the engine. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.

Disclosed is an electronic device including a communication circuit and a processor. The processor may be configured to communicate with an external electronic device based on a specified protocol, using the communication circuit, to receive first information at least including type information of the external electronic device based on the specified protocol, using the communication circuit, and to determine a positioning master for measuring a distance between the electronic device and the external electronic device based at least on the first information among the electronic device and the external electronic device. Other various embodiments as understood from the specification are also possible.

Systems and methods for localization and passive entry/passive start (PEPS) systems for vehicles are provided. A communication gateway in a vehicle configured to establish a Bluetooth low energy (BLE) communication connection with a portable device. Sensors are configured to measure signal information about a communication signal sent from the portable device. A localization module is configured to receive the signal information from the sensors and determine a location of the portable device based on the signal information. A passive entry/passive start (PEPS) system is configured to receive the location of the portable device from the localization module and perform 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. Each of the plurality of sensors are synchronized.

A portable device is configured to establish a Bluetooth low energy (BLE) communication connection with a vehicle and to communicate with at least one sensor in the vehicle using impulse radio (IR) ultra-wide band (UWB) communication after establishment of the BLE communication connection with the vehicle is completed. A location of the portable device is determined by the vehicle based on ranging using IR UWB communication performed by the at least one sensor.

A system for starting an engine of a vehicle has a fuel injector injecting fuel into a closed intake port to form an air fuel mixture. The system also includes an actuator rotating a crankshaft in a first direction to open the intake port by moving a piston within a cylinder coupled to the crankshaft. A combustion chamber defines between the cylinder and the port receiving the air fuel mixture through the intake port. The actuator rotates the crankshaft in a second direction to close the intake port. A spark plug ignites the air fuel mixture to start the engine. The engine also includes many other disclosed features.

A lock control apparatus for a vehicle includes anchors to receive a signal transmitted from a terminal; a communication module to communicate using controller area network (CAN) communication; a detector installed on a door to input a detection signal; and a processor to receive the signal transmitted from the terminal from at least one of the anchors through the communication module, calculate a position of the terminal based on the signal transmitted from the terminal, determine whether to unlock the door in response to the position of the terminal and the detection signal, and control an engine to start. The processor controls the anchors to enter a sleep mode in response to waiting times of the anchors and resets the anchors to release the sleep mode and controls the anchors to enter a waiting mode in response to the number of anchors transmitting the signal from the terminal.

A vehicle authentication device includes an electronic control unit. The electronic control unit is configured to display predetermined verification information on a display device, receive, via an information processor possessed by a user, information on an operation performed by the user after the verification information is displayed, and determine that the information processor is present inside a vehicle cabin, when the information on the operation has a predetermined correspondence with the verification information.
