A power door system for a vehicle including a plurality of power-operated doors is provided. The system includes a passive remote entry device configured to emit a signal to one or more cooperating vehicle receivers and a controller configured to cause the power door system to open the at least one power-operated door when the passive remote entry device signal is received and an individual is detected in a predefined activation zone for a predetermined period of time. The system further includes a vehicle-mounted user detection device. The passive remote entry device may be selected from the group consisting of a key fob, a smart key, a key card, a cellular telephone or smartphone configured with a phone-as-a-key function, a Bluetooth®-activated and vehicle-recognized cellular telephone, a Bluetooth®-activated and vehicle-recognized smartphone, and a Bluetooth®-activated and vehicle-recognized smartwatch. Methods for controlling a power door system for a vehicle are described.

A method for determining the distance between an authentication device carried by a user and a motor vehicle, each including a wireless communication module so as to exchange a data frame, the data frame being modulated by changing the phase of a reference signal. The method includes the following steps of: the vehicle receiving a modulated reference signal, sent by the device, demodulating the received signal in order to extract an in-phase component and a quadrature component therefrom, computing the power value of the signal on the basis of the maximum amplitude value of the in-phase component and of the maximum amplitude value of the quadrature component, and determining the distance between the device and the vehicle on the basis of the computed power value.

A vehicle security system may include a vehicle controller and a first wireless communications device coupled thereto, and at least one wireless sensor. The wireless sensor may include a housing having a threaded mounting surface, a motion sensor carried by the housing, a second wireless communications device carried by the housing, and a sensor controller carried by the housing. The sensor controller is configured to determine when motion of the housing exceeds a first threshold, and send a first security alert message to the vehicle controller based thereon via the second and first wireless communications devices, and determine when the first threshold is exceeded for a predetermined time and enter a power saving mode based thereon. The at least one sensor may also include a power source carried by the housing to power the motion sensor, second wireless communications device, and sensor controller.

The invention relates to a method (100) for remotely controlling at least a first function of a security device (1) of a vehicle (2), wherein a remote control device (10) has a first radio unit (12), whereby a connection to a mobile radio network (4) can be established. According to the invention, the following steps are carried out: a) determining the position of the vehicle (2) b) determining the position of the remote control device (10) c) determining an actual distance (20) between the position of the vehicle (2) and the remote control device (10) d) comparing the actual distance (20) with at least one defined specified distance (21), wherein the first function is activated if the actual distance (20) is less than or equal to the specified distance (21).
