Abstract: A method for transition between driving modes of a vehicle is disclosed. The driving modes include an autonomous driving (AD) mode, a partly autonomous driving (PAD) mode and a manual driving (MD) mode. A transition from the PAD mode to the AD mode is performed by enabling the AD mode. A transition from the AD mode to the PAD mode is performed by releasing a steering wheel lock when the PAD mode is in an enabled state. A transition from the MD mode to the AD mode is performed by enabling the AD mode. A transition from the AD mode to the MD mode is performed by releasing the steering wheel lock when the PAD mode is in a disabled state. A system for performing the method and a vehicle including the system are also disclosed.

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.

Abstract: An apparatus and method are disclosed for vehicle occupant protection in large animal collisions. Objects forward of the host vehicle are monitored using at least one forward looking remote sensor and object signals output. A velocity of the host vehicle is determined and velocity signals output. The object signals and the velocity signals are processed to determine whether the host vehicle unavoidably will suffer a collision with a large animal while traveling at or above a threshold velocity and a collision signal is output. Operation of a motor operated height adjustment device, an inclination adjustment device and/or a longitudinal position adjustment device of a vehicle seat is triggered to move a seat cushion and a backrest thereof away from a leading edge of a roof of the host vehicle in response to the collision signal.

Abstract: A method and apparatus are disclosed for vehicle occupant protection in unintentional roadway departure by a vehicle having at least one vehicle seat with a seat cushion mounted on a seat frame, the height of which is adjustable through a motor operated height adjustment device. Vehicle travel is monitored using a remote sensor and/or a vehicle dynamics sensor. The remote sensor detects edges of the road. The vehicle dynamics sensor determines vehicle dynamics parameters. Road edge signals and/or vehicle dynamics signals are processed to determine whether the vehicle is about to leave the road. Operation of the height adjustment device to move a seat cushion towards a crash-position is triggered in response to an off-road signal indicating that the vehicle is about to leave the road.

Abstract: A method performed by a retraction control system of a vehicle for controlling refraction of a seat belt of a reversible seat belt refractor arrangement for a vehicle occupant is provided. The control system determines fulfillment of an activation condition based on an initiating input derived from a vehicle situation sensing system, which initiating input indicates that the vehicle, at an initiating time instant, is considered likely to be, or is about to become, involved in a hazardous situation and/or uncomfortable dynamic situation. The control system generates an activation signal utilizable for initiation of retraction of the seat belt. If the control system determines absence of fulfillment of a confirming condition within a predetermined confirming time period, and/or if the control system determines fulfillment of an abort condition within a predetermined abort time period, the control system generates a deactivation signal utilizable for aborting the initiation.

Abstract: A system for determining a position of a living being in a vehicle interior includes at least three components, each component of a first type or a second type, one of the first or second type being a transmitter and the other a receiver. Two components are of the first type and one component is of the second type. Each component is adapted to transmit or receive a signal dependent on type. The signal is adapted for determining a presence of the living being and for determining a distance (d1, d2) between the living being and each component of the first type. The components have active sectors adapted to at least partly overlap within the vehicle interior. The components of the first type are located at different positions known relative to each other. The system is adapted to determine the living being position based on the determined distances (d1, d2).

The method may also include the evaluation algorithm evaluating if the signal is within the selectable fire interval, and in that case activating the pedestrian protection device.

Abstract: An air bag deployment system includes a pre-impact sensor operative to detect an imminent impact and at least one post-impact sensor operative to detect an impact. An air bag has a non-deployed volume, a pre-impact deployed volume, and a post-impact deployed volume smaller than the pre-impact deployed volume. The air bag is deployed to the pre-impact volume wherein the air bag deployment system is arranged to deploy the air bag before the impact and the at least one air bag is deployed into the pre-impact deployed volume, in reaction to the imminent impact, and to the post-impact deployed volume in reaction to the impact. The system provides for enhanced occupant safety during a collision by allowing pre-impact deployment of the air bag in order to utilize the full possible length of deceleration for the occupant as the impact pulse affects the occupant.
