Abstract
A method for the dynamic fixation of an occupant wearing a seatbelt on a vehicle seat involves determining a lateral acceleration of the vehicle and a road course ahead of the vehicle. The seatbelt is tightened with a predetermined belt force for a predetermined period of time before entering a bend having a certain curvature.
Claims8
A method for the dynamic fixation of an occupant wearing a seatbelt on a vehicle seat of a vehicle, the method comprising:
- determining a lateral acceleration of the vehicle and a road course ahead of the vehicle;
- predicting a maximum lateral acceleration occurring when driving through a bend ahead of the vehicle;
- and
- tightening the seatbelt with a first predetermined belt force for a predetermined period of time
- responsive to the predicted maximum lateral acceleration exceeding a first predetermined threshold value, wherein the predetermined period of time is before the vehicle reaches the predicted maximum lateral acceleration, or
- responsive to the bend having a predetermined curvature, wherein the predetermined period of time is before the vehicle enters the bend having the predetermined curvature;
- determining whether a lateral acceleration of the vehicle while the vehicle is driving through the bend exceeds a second predetermined threshold value;
- and
- tightening the seatbelt with a second predetermined belt force, which is higher than the first predetermined belt force, responsive to the determination that the lateral acceleration of the vehicle while the vehicle is driving through the bend exceeds the second predetermined threshold value, which is higher than the first predetermined threshold value.
