A system for improving safety of an occupant by a vehicle seat belt, which can provide adaptive protection for an occupant in different seat positions and different sitting postures is provided. A method for improving safety of an occupant by a vehicle seat belt is also provided, along with a computer-readable medium. The a system for improving safety of an occupant by a vehicle seat belt includes an in-vehicle observation system, an active seat belt system, and an integrated safety domain control unit. The integrated safety domain control unit formulates a vehicle seat belt protection strategy based on received data from the in-vehicle observation system, and a slack state of an active retractor and a positional state of an active lift buckle in the active seat belt system, to implement selective tightening or loosening of the active retractor and/or selective lifting or lowering of the active lift buckle.

Method for controlling a vehicle including a smartphone-engaging coupling element. Data about operational status of the vehicle is transferred from one or more vehicle-resident systems to a smartphone when the smartphone is engaged with the coupling element. Commands are received by the vehicle from the smartphone when the smartphone is engaged with the coupling element, which commands being based in part on data previously transferred from the vehicle-resident system(s) to the smartphone when the smartphone is engaged with the coupling element. A vehicular system, e.g., seat positioning system, mirror positioning system, passenger compartment temperature control system, route guidance or navigation system, changes its operation in accordance with the commands received by the vehicle from the smartphone when the smartphone is engaged with the coupling element.

A method is provided for operation of a safety arrangement in a vehicle. The safety arrangement comprises a seat belt, a seat belt retractor and at least one seat position adjustment arrangement for position adjustment of a seat of the vehicle and/or a portion of the seat. The method comprises a refraction of the seat belt by means of the seat belt retractor with a retraction force, and a pre-crash displacement of the seat and/or the portion of the seat resulting in a displacement force acting on the seat belt. The method further comprises adapting the pre-crash displacement and the refraction of the seat belt to each other by ascertaining that a combined seat belt force comprising the refraction force and the displacement force does not exceed a selectable level. The disclosure further relates to a safety arrangement for a vehicle and a vehicle comprising such a safety arrangement.

An occupant restraint device is configured to restrain an occupant seated in a seat of a vehicle. The occupant restraint device includes a seat belt unit and a seat belt controller. The seat belt unit is configured to perform a restraint of the occupant by actuating a motor and winding a webbing. The seat belt controller is configured to control the seat belt unit to suit a drive mode of the vehicle. The seat belt controller is configured to, when the drive mode of the vehicle is switched to a rough road mode suitable for driving on a rough road or a sports mode suitable for sports driving, control the seat belt unit to perform the restraint of the occupant.
