Abstract
A method for determining an approach of a person toward a transportation vehicle, a computer program, an apparatus, and a system. In response to UWB technology or other radio-based distance systems being used for the Kessy access, the distance information relating to a user is gathered. In response to the access device containing an acceleration sensor, the movement sequence relating to the distance information is analyzed. The magnetic orientation of a transportation vehicle is known when the transportation vehicle is parked, and this information is included in the analysis. In the course of the calculation, directional vectors are included in the approach detection, and the individual positions are easily calculated.
Claims16
A method for determining an approach of a person to a transportation vehicle, the method comprising:
- receiving transportation vehicle data with information on a magnetic orientation of the transportation vehicle;
- receiving keyless data including UWB ranging data of a keyless device from the keyless device of the transportation vehicle;
- detecting an orientation of a device guided by the person and generating sensor data with information about the orientation of the device, wherein detecting the orientation of the device guided by the person includes detecting a magnetic orientation of the device;
- and
- analyzing the keyless data and determining a distance between the person and the transportation vehicle based on the keyless data;
- and
- analyzing the sensor data and the transportation vehicle data and determining a directional vector between the person and the transportation vehicle based on the sensor data and the transportation vehicle data,
- wherein a rotation of the device is detected based on sensor data from an acceleration sensor and/or a gyroscope sensor of the device and the sensor data are weighted higher than the UWB ranging data in response to detected rotation of the device being more than a rotation angle of 130°, and/or
- wherein a light sensor of the device is used to determine whether the device is in a pocket of the person and the sensor data are weighted higher than the UWB ranging data in response to determination that the device is in the pocket of the person.
A device for determining an approach of the device to a transportation vehicle, the device comprising:
- a sensor configured to detect an orientation of the device guided by a person and for generating sensor data, wherein the sensor has a magnetic field sensor, and the detection of the orientation of the device guided by the person includes detection of a magnetic orientation of the device;
- an input interface configured to receive keyless data including UWB ranging data of a keyless device from the keyless device of the transportation vehicle, the sensor data including information on the orientation of the device and transportation vehicle data with information on a magnetic orientation of the transportation vehicle;
- an analysis unit configured to analyze the keyless data and determine a distance between the person and the transportation vehicle based on the keyless data and configured to analyze the sensor data and the transportation vehicle data and determine a directional vector between the person and the transportation vehicle based on the sensor data and the transportation vehicle data, and
- an output interface configured to transmit the determined directional vector;
- wherein a rotation of the device is detected based on the sensor data from an acceleration sensor and/or a gyroscope sensor of the device and the analysis unit weights sensor data higher than the UWB ranging data in response to detected rotation of the device being more than a rotation angle of 130°, and/or
- wherein a light sensor of the device is used to determine whether the device is in a pocket of the person and the sensor data are weighted higher than the UWB ranging data in response to determination that the device is in the pocket of the person.
