A method and apparatus for controlling deployment of the pedestrian head protection devices on a motor vehicle having a metal bumper are disclosed. The disclosed inventive concept involves strategic placement of accelerometer sensing devices and the derivation of a real time impact signal from the signals generated by the accelerometers. This real time impact signal is used along with thresholds and time window to control deployment. The apparatus includes a metal bumper, two support brackets attaching the bumper to the vehicle and at least two accelerometers fitted to the bumper proximate the brackets. The derivation and use of a single impact signal from said first and second signal-generating accelerometers is achieved by taking the larger of two absolute values derived from the accelerometers.
