ABSTRACT:
The invention relates to an acceleration detector for use as a decelerometer for controlling an electrically operated axle brake, particularly for a towed vehicle.
The acceleration detector comprises a movable member which is capable of moving against the action of elastic means permanently urging it towards a stop, and a fixed member comprising a proximity detector adapted to generate a voltage proportional to the distance separating it from the movable member.
According to the invention, the stop for the movable member is spaced from the proximity detector by a predetermined distance such that, as soon as the proximity detector is switched on, for example by depressing the brake pedal of the towing vehicle, the output voltage of the detector is other than zero.
