Embodiment Construction

[0019] First refer to figure 1 , shows a schematic diagram of the vehicle 1 . As is known in the prior art, the vehicle 1 has a number of sensors adapted to sense the position, movement and control of the vehicle 1 . These sensors include a set of accelerometers 2 to measure the acceleration a of the vehicle 1 in the longitudinal direction x x , the acceleration a in the transverse direction y y , and the vertical direction (in figure 1 pointing directly out of the paper) the acceleration a z . The velocity of the vehicle 1 in multiple directions can also be determined from the output of these accelerometers 2, and the vehicle's longitudinal velocity v x can be obtained from the speedometer. Accelerometer 2 also includes a yaw sensor to measure the yaw rate ω z . A GPS or other positioning system 3 is provided to determine the position of the vehicle 1 on the surface of the earth. Sensors 4 are further provided to detect the angle α of the steering wheel, the angle β ...

Abstract

A vehicle safety system comprising: at least one occupant safety device (6) for protecting an occupant of the vehicle (1) in the event of a side impact: and a control unit (7) operable to receive information from one or more vehicle sensors (2, 3, 4, 5) and to provide a trigger signal to activate the occupant safety device (6), wherein: under normal driving conditions, a default deployment algorithm is used by the control unit (7) to determine whether the trigger signal should be generated; and if it is determined that loss of control of the vehicle (1) is occurring, or is expected to occur, and the longitudinal speed of the vehicle (1) exceeds a first threshold, the control unit (7) employs a first further deployment algorithm to determine whether the trigger signal should be generated, the first further deployment algorithm being adapted to cause the trigger signal to be generated a shorter time after the initiation of a side impact than is the case for the default deployment algorithm.

Description

technical field [0001] The present invention relates to vehicle safety systems, and in particular to systems for protecting vehicle occupants in various types of crash situations. Background technique [0002] Although most vehicles are typically equipped with safety equipment to protect the occupants of the vehicle in the event of a side collision. Generally speaking, the lateral distance between the vehicle occupants and the exterior of the vehicle is small because of the thin sides of the vehicle. It is therefore important to activate safety equipment, such as interior side airbags adapted to protect passengers in the event of a side impact, at the earliest possible stage. [0003] In some cases, for example by using radar or LIDAR detection, it may be possible to detect an imminent side collision and activate one or more appropriate vehicle safety systems prior to the collision. In other cases, crash sensors are used to detect side impacts, and thus vehicle safety syst...
