Method and system for operating motor vehicle

The invention relates to a method for operating a motor vehicle (2) having at least one vehicle communication means (3) fixed to a vehicle body, in which a signal is transmitted by a user device (4) which can be actuated independently of the motor vehicle (2) and which can be assigned or is assigned to a driver of the motor vehicle (2) and is received by the vehicle communication means (3), and wherein the distance between the user device (4) and the motor vehicle (3) is monitored on the basis of the received signal. According to the invention, the distance is monitored during operation of the motor vehicle (2), and a safe operating state of the motor vehicle (2) is activated when a distance exceeding a predetermined threshold value is detected. 本发明涉及一种用于运行机动车(2)的方法，所述机动车具有至少一个固定至车身的车辆通信器件(3)，其中，信号由可以独立于机动车(2)操纵并且可以分配或被分配给机动车(2)的驾驶员的用户设备(4)发送并且由车辆通信器件(3)接收，并且其中根据接收到的信号，监控用户设备(4)和机动车(3)之间的距离。规定，在机动车(2)的运行中监控距离，并且在检测到超过预定阈值的距离时激活机动车(2)的安全运行状态。
