A method for operating functional unit of a motor vehicle using an identification system, in which at least a first authorization is requested for operating the functional unit and an identification signal is transmitted to an identification device by an identification element of the identification system. The functional unit is operated after receiving and the functional unit is only operated in a second authorization. The second authorization is generated by the identification device. Using the identification device, a first signal duration of the identification signal is determined for determining a first spacing of the identification element at a first point in time, and a second signal duration of the identification signal is determined for determining a second spacing of the identification element at a second point in time, and the second authorization is generated depending on a comparison.

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.

Particular embodiments may enable configuring settings of a vehicle in a designated mode. A signal to place the vehicle in a designated mode may be received. A roll angle and a pitch angle of the vehicle as parked may be assessed based on data received from a position sensor built into the vehicle. Signals to adjust an electronically controlled suspension of the vehicle to reduce the roll angle or the pitch angle so that the vehicle is level as parked may be sent based on the assessed roll angle and pitch angle exceeding a threshold value. One or more settings of the vehicle to change default operating characteristics by the vehicle while in the designated mode may be modified.

An automated parking system and a method enable a driverless vehicle to autonomously travel and park in a vacant parking slot through communication with a parking infrastructure. The automated parking system and method also control the driverless vehicle to autonomously travel from a parking slot to a pickup area through communication with the parking infrastructure.

A portable device includes a reception antenna and a strength meter. The reception antenna includes antennas of three axes each receiving a first signal and a second signal. The strength meter measures a reception strength of the request signal and the request signal received by each of the three axes of the LF receiver. A relay attack determination device is provided with a comparator that executes a comparative process of strength ratios of the request signal and the request signal based upon a measurement value of the reception strength. In a case where the three axes include an ineffective axis, in which the measurement value of the reception strength of the request signal or the request signal deviates from a usable range, the comparator excludes the ineffective axis and executes the comparative process.

A vehicle operation detection device includes sensors laid out in a vehicle along an axis in an opening-closing direction of a door of the vehicle. When the user moves a part of a body toward the sensors and a motion of moving the part of the body along the axis is detected, the sensors detect an opening-closing operation for the door. The vehicle operation detection device further includes light-emitting members laid out in the vehicle along the axis in the opening-closing direction and an operation direction indicator configured to drive the light-emitting members in sequence in a first direction in a fully-closed state of the door and drives the light-emitting members in sequence in a second direction in a fully-open state of the door.
