Abstract
The present disclosure relates to a method for operating a safety system of a vehicle, which safety system comprises a remote sensor, an impact sensor and a protection system adapted to be activated by the impact sensor. The method includes scanning a selectable region in front of the vehicle by means of the remote sensor, determining that the selectable region provides a free path for the vehicle based on information from the remote sensor, and lowering a sensitivity of the impact sensor. The disclosure further relates to the safety system and a vehicle comprising the safety system.
Claims19
A method for operating a safety system of a vehicle, wherein the safety system includes a remote sensor, an impact sensor and a protection system, the protection system adapted to be activated by the impact sensor, the method comprising:
- scanning a selectable region of a road in front of the vehicle by the remote sensor;
- detecting an object distinct from the road in the selectable region in front of the vehicle;
- providing at least three objects categories, namely, a “Fire Object”, a “No-Fire Object”, and an “Other Object”, and classifying each object detected distinct from the road into one of the at least three object categories;
- determining that the selectable region provides a free path for the vehicle based on information from the remote sensor, when there is no “Fire Object” present in the selectable region and 0-n “No-Fire Object(s)” present in the selectable region, n being a positive integer;
- lowering a sensitivity of the impact sensor in response to determining that the selectable region provides a free path for the vehicle;
- and
- controlling activation of the protection system based on the lowered sensitivity of the impact sensor.
A safety system of a vehicle, the safety system comprising:
- a remote sensor for scanning a selectable region of a road in front of the vehicle;
- an impact sensor for detecting an impact or an imminent impact with the vehicle and for activating a protection system;
- a determination unit for determining whether the selectable region provides a free path for the vehicle based on information from the remote sensor;
- and
- an adjustment unit adapted to lower a sensitivity of the impact sensor if determined that the selectable region provides a free path for the vehicle;
- a classifier adapted for providing at least three objects categories, namely, a “Fire Object”, a “No-Fire Object”, and an “Other Object”, and classifying each object detected distinct from the road in the selectable region into one of the at least three object categories;
- wherein the determination unit is adapted to determine that the selectable region provides the free path for the vehicle based on information from the remote sensor, when there is no “Fire Object” present in the selectable region and 0-n “No-Fire Object(s)” present in the selectable region, n being a positive integer.
