A method for controlling a vehicle is applied to an in-vehicle terminal, includes: obtaining current position information of a vehicle and a preset electronic fence, determining a travel direction according to the current position information and the preset electronic fence; when determining that the vehicle travels from the inside of the preset electronic fence to the outside of the preset electronic fence, determining a current position state of the vehicle according to the current position information, where the position state represents a relative position of the vehicle and the preset electronic fence; determining whether the current position state is the same as a previous position state of the vehicle; and when the current position state is different from the previous position state, performing one or two of outputting warning information and sending a key shielding signal, to enable a key controller to shield a key control signal of the vehicle.

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.

A first device includes: a first reference signal source; a first transmitting/receiving unit which transmits two or more first carrier signals and receives two or more second carrier signals using an output of the first reference signal source; and a calculating unit. A second device includes: a second reference signal source configured to be operated independently from the first reference signal source; and a second transmitting/receiving unit configured to transmit two or more second carrier signals and receive two or more first carrier signals using an output of the second reference signal source. A frequency group of two or more first carrier signals and a frequency group of two or more second carrier signals differ from each other. The calculating unit calculates a distance between the first device and the second device based on a phase detection result obtained by receiving the first and second carrier signals.

A vehicle control device includes a processor a memory storing program instructions executable by the processor to transmit a virtual key enabling an operation on a vehicle through automated valet parking control to another device by using a communicator communicating with the other device; and an operation controller configured to operate the vehicle according to operation information of the vehicle in a case where the communicator receives use information of the virtual key.

An apparatus, a key partner, methods and computer programs for a key module of a vehicle and a vehicle. The apparatus for the key module includes a communication interface for radio communication with a key partner of the vehicle, a motion sensor, and a control module for controlling an operating state from operating states of the key module based on the information about the motion of the key module. The operating states include at least a first operating state, a pre-shutdown operating state and a shutdown state. The control module activates the first operating state if the motion of the key module is above a motion limit value and activates the pre-shutdown operating state if the motion of the key module is below the motion limit value over a period of time.

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.

A firmware update system includes a microcontroller which includes an encryption module configured to perform an encryption function. An update module is configured to communicate with the microcontroller to provide a firmware update. The update module includes a decryption module configured to convert the firmware update from plaintext into decryption ciphertext using a decryption function. The encryption module is configured to convert the decryption ciphertext into plaintext such that the microcontroller can execute the plaintext to implement the firmware update.

A vehicle includes: at least one memory configured to store at least one default Instruction Structure Key (ISK), a generated ISK, and a pin code of the vehicle; and at least one processor. The at least one default ISK may include a first default ISK and a second default ISK. The processor may generate a random number using the first default ISK, receive the second default ISK encrypted with the generated ISK generated based on the pin code, and determine the generated ISK as an encryption key for encryption communication of the vehicle when the generated random number and the random number corresponding to the second default ISK are the same.

A vehicle control system includes a vehicle-mounted device and a mobile device portable by a user. The vehicle-mounted device permits a predetermined operation on a vehicle based on a response signal transmitted from the mobile device in response to a request signal from the vehicle-mounted device. The vehicle-mounted device includes a first communication device performing a wireless communication with the mobile device under a predetermined communication protocol different from that of the request signal. The mobile device includes: a second communication device performing the wireless communication with the first communication device; and a response control unit that responds to the request signal under a condition that the mobile device is located in a communication range of the first communication device and the wireless communication between the first communication device and the second communication device is established.

The disclosure relates to a method to lock, unlock and start a vehicle without using a radio key or electronic vehicle key. According to the disclosure, the function of starting the vehicle without actively using the key is blocked when the vehicle is locked. When the vehicle is unlocked in a manner secured against relay station attacks, the possibility exists of starting the vehicle without actively using the key.
