Embodiments of the invention provide an apparatus for monitoring one or more target objects in an environment external to a host vehicle by means of at least one sensor, the apparatus being arranged to trigger at least one action responsive to the detectio...

Early actuation of an active device of a vehicle (e.g. a seat belt tensioner) is provided by applying rate of change of brake pressure to monitored brake pressure (52), so as to produce a modified brake pressure characteristic (51) which is advanced in tim...

A method of determining the category of action of an active device of a vehicle comprises repeatedly measuring a vehicle parameter indicative of a change of vehicle state, determining a rate of change of the vehicle parameter and determining a modified veh...

A method of triggering an active device of a vehicle at a pre-determined threshold comprises generating a steering wheel signal from steering angle rate of change of steering angle of the vehicle, the signal representing an advance in time in comparison to...

An active device of a vehicle, for example a seat belt tensioner, is triggered by reference to an estimated vehicle roll rate exceeding a threshold roll rate. The estimated vehicle roll rate may be conditioned according to vehicle speed, and is determined ...

An apparatus comprises a fuel burning actuator (110) operable to burn fuel to drive generator means (115) to generate charge to recharge an energy storage means (120). The apparatus is operable to motor the fuel burning actuator (110) by means of motoring ...

An attenuator for the air inlet tract of an internal combustion engine comprises an unobstructed tube (4) having a surrounding enclosure (9) divided into a primary chamber (11) in fluid communication with the inlet tube, and a secondary chamber (12) in flu...

The present invention relates to a motor vehicle (1) with a grab handle (6), particularly a grab handle in a passenger compartment (12). The grab handle (6) is secured to a support, such as a roof panel (14), at a pair of pivot points (16), so that the han...
