Abstract:
A method of activating a passenger safety arrangement of a vehicle, the method including reading in a roll rate of the vehicle and triggering the passenger safety arrangement when, at a first time, at least one roll rate value is present, which exhibits a positive sign and is larger than a roll rate positive threshold value and when, at a second time after the first time, at least one roll rate value is present, which exhibits a negative sign and is smaller than a roll rate negative threshold value.

Abstract:
A safety system for a motor vehicle having at least a front wheel arrangement having one or more wheels and rear wheel arrangement having one or more wheels, the arrangement having: a control unit; and one or more vehicle inertial sensors to detect acceleration experienced by the vehicle, the inertial sensors being connected to the control unit so the control unit receives output signals from the inertial sensors; and one or more vehicle safety systems which may be activated by the control unit, wherein the control unit is configured to process the signals received from the inertial sensors and to determine whether at least one of the wheels of the front and rear wheel arrangements is not in contact with the surface over which the vehicle is driven.
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.
Abstract:
A method and a system for controlling an adaptive belt force limiter (ABLL) for a vehicle safety belt in a vehicle provided with at least one closing velocity sensor (CVS) for detecting objects in front of the vehicle. The CVSs are capable of sensing the presence of an object in at least two different spatial areas and generating area specific signals. The signals are transmitted to a restraints control module (RCM) which uses the sensor signals in order to generate a control signal for the ABLL. The control signal generated depends on the spatial area from which the sensor signals originate. A CVS is capable of sensing the presence of an object in at least two different spatial areas and is able to distinguish the sensed signals from each other in order to control the ABLL.
Abstract:
A safety arrangement incorporates a seat-belt (3) to protect an occupant (2) of a vehicle seat (1). A control unit (11) incorporates a calculator (18) to calculate the weight of the occupant (2) of the seat occupant, by comparing the force (6) applied to the seat-belt by the seat occupant with the acceleration (14) of the compartment. A controller (19) controls a restraining force applied to the seat occupant by the safety-belt and, possibly, additional force limiting or energy absorbing devices such as an air-bag (8).
