Abstract
A method for operating a motor vehicle having at least one vehicle communication arrangement fixed to the body. Signals are emitted by a user device, which can be handled independently of the motor vehicle and can be assigned or is assigned to a driver of the motor vehicle, and are received by the vehicle communication arrangement. A distance between the user device and the motor vehicle is monitored on the basis of the received signals. Provision is made for the distance to be monitored during operation of the motor vehicle and for a safety operating state of the motor vehicle to be activated when a distance exceeding a predefined threshold value is detected.
Claims13
A method for operating a motor vehicle having at least one vehicle communication arrangement fixed to a body of the motor vehicle, the method comprising the following steps:
- emitting signals by a user device, which can be handled independently of the motor vehicle and can be assigned or is assigned to a driver of the motor vehicle;
- receiving the emitted signals by the vehicle communication arrangement;
- monitoring a distance between the user device and the motor vehicle based on the received signals, wherein the distance is monitored during operation of the motor vehicle;
- determining whether the distance exceeds a predefined threshold value at a first time;
- setting at the first time, in response to determining that the distance exceeds the predefined threshold value, a second time subsequent to the first time;
- and
- activating a safety operating state of the motor vehicle when the second time is reached.
A method for operating a motor vehicle having at least one vehicle communication arrangement fixed to a body of the motor vehicle, the method comprising the following steps:
- emitting signals by a user device, which can be handled independently of the motor vehicle and can be assigned or is assigned to a driver of the motor vehicle;
- receiving the emitted signals by the vehicle communication arrangement;
- monitoring a distance between the user device and the motor vehicle based on the received signals, wherein the distance is monitored during operation of the motor vehicle;
- and
- activating a safety operating state of the motor vehicle based on detecting that the distance exceeds a predefined threshold value,
- wherein based on detecting the distance exceeding the threshold value, a braking device of the motor vehicle is actuated for the purposes of generating a braking torque,
- wherein the motor vehicle and/or the user device emits an emergency call signal fully automatically when the distance exceeding the threshold value is detected, and wherein the emergency call signal contains information regarding a traveling speed of the motor vehicle at a time of the detection of the distance exceeding the threshold value and/or regarding the distance between the user device and the motor vehicle after the deceleration of the motor vehicle to a standstill.
A system, comprising:
- a motor vehicle having at least one vehicle communication arrangement fixed to a body of the motor vehicle;
- at least one user device which can be handled independently of the motor vehicle, wherein the vehicle communication arrangement is configured to receive signals emitted by the user device;
- and
- a controller configured to:
- monitor a distance between the user device and the motor vehicle during operation of the motor vehicle based on the received signals,
- determine whether the distance exceeds a predefined threshold value at a first time,
- set at the first time, in response to determining that the distance exceeds the predefined threshold value, a second time subsequent to the first time, and
- activate a safety operating state of the motor vehicle when the second time is reached.
