Cargo detection system and method for detecting overhanging cargo on a motor vehicle
A cargo detection system for detecting overhanging cargo on a motor vehicle comprises a sensor system configured to provide cargo measurement data for cargo loaded onto the motor vehicle by measuring at least one of exterior dimensions of cargo protruding over an outer edge of the motor vehicle and an opening condition of a tailgate of the motor vehicle. The system further comprises a control device configured to assess, based on the cargo measurement data of the sensor system, whether cargo is overhanging from the motor vehicle and to calculate an updated vehicle length and/or vehicle width for the motor vehicle accounting for the overhanging cargo.
1. A cargo detection system for detecting overhanging cargo on a motor vehicle, the cargo detection system comprising:
a sensor system configured to provide cargo measurement data for cargo loaded onto the motor vehicle by measuring at least one of exterior dimensions of cargo protruding over an outer edge of the motor vehicle and/or an opening condition of a tailgate of the motor vehicle; and
a control device configured to assess, based on the cargo measurement data of the sensor system, whether cargo is overhanging from the motor vehicle and to calculate an updated vehicle length and/or vehicle width for the motor vehicle accounting for the overhanging cargo,
wherein the control device is configured to estimate a blind spot region at a distal end of the overhanging cargo, based on a field of view of the sensor system, and to add a corresponding blind spot extension to the updated vehicle length and/or vehicle width.
2. The cargo detection system according to claim 1 , wherein the sensor system is configured to measure the exterior dimensions of cargo protruding over at least one of a cargo area, a trunk, a tailgate, and/or a bumper of the motor vehicle.
3. The cargo detection system according to claim 1 , wherein the opening condition comprises an opening angle (x) of the tailgate.
4. The cargo detection system according to claim 1 , wherein the sensor system comprises at least one of a camera, a radar, an ultrasonic sensor, and/or a lidar.
5. The cargo detection system according to claim 1 , wherein the sensor system is mounted at least of one of the cargo area, the trunk, the tailgate, and/or the bumper of the motor vehicle.
6. The cargo detection system according to claim 1 , wherein the sensor system is configured to measure a protrusion length (L OV ) of the overhanging cargo of at least up to 3m and/or a protrusion width of the overhanging cargo of at least up to 1.5m.
7. The cargo detection system according to claim 1 , further comprising:
a communication device configured to receive cargo measurement data recorded by an external measuring entity for the cargo loaded onto the motor vehicle via vehicle-to-everything (V2X) communication.
8. The cargo detection system according to claim 1 , further comprising:
a driver interface configured to provide a cargo advice signal based on the updated vehicle length and/or vehicle width.
9. A motor vehicle comprising a cargo detection system according to claim 1 .
10. The motor vehicle according to claim 9 , further comprising:
a parking assistant configured to use the updated vehicle length and/or vehicle width as input.
11. A method for detecting overhanging cargo on a motor vehicle, the method comprising:
measuring, by at least one of a sensor system of the motor vehicle and/or an external measuring entity, at least one of
exterior dimensions of cargo protruding over an outer edge of the motor vehicle, and/or
an opening condition of a tailgate of the motor vehicle;
assessing, by a control device of the motor vehicle, based on the cargo measurement data, whether cargo is overhanging from the motor vehicle; and
calculating, by the control device of the motor vehicle, at least one of an updated vehicle length and/or an updated vehicle width for the motor vehicle accounting for the overhanging cargo,
wherein the control device estimates a blind spot region at a distal end of the overhanging cargo, based on a field of view of the sensor system, and adds a corresponding blind spot extension to at least one of the updated vehicle length and/or the updated vehicle width.
12. The method according to claim 11 , wherein the sensor system measures the exterior dimensions of cargo protruding over at least one of a cargo area, a trunk, a tailgate, and/or a bumper of the motor vehicle.
13. The method according to claim 11 , wherein the opening condition comprises an opening angle of the tailgate.
14. The method according to claim 11 , wherein the sensor system measures a protrusion length (L OV ) of at least one of the overhanging cargo of at least up to 3m and/or a protrusion width of the overhanging cargo of at least up to 1.5m.
15. The method according to claim 11 , further comprising:
receiving, by a communication device of the motor vehicle, cargo measurement data recorded by the external measuring entity for the cargo loaded onto the motor vehicle via vehicle-to-everything (V2X) communication.
16. The method according to claim 11 , further comprising:
providing, by a driver interface of the motor vehicle, a cargo advice signal based on at least one of the updated vehicle length and/or the updated vehicle width.
17. The method according to claim 11 , wherein at least one of the updated vehicle length and/or the updated vehicle width is used as input for a parking assistant of the motor vehicle.
