A vehicle weight sensing system particularly useful for trailers. An axle tube is mounted to the vehicle or trailer through its suspension members that may be leaf springs. A mounting block is affixed to the axle tube for mounting a strain gauge. The mounting block is fixed to the axle tube between the suspension members connected to the axle tube. The mounting block has a mounting surface opposite to the mating surface and a notch extends from the mating surface toward the mounting surface. The notch terminates between the mating surface and the mounting surface. The notch separates rigidified sections of the mounting block and the rigidified sections straddle the notch. The stain gauge measures strain in the axle and thereby generates a signal proportional to the weight on the trailer. The signal can be used to properly proportion a brake system on the trailer.
A method for controlling a braking force applied to a trailer, the method comprising:
A method of controlling a braking force applied to a trailer, the trailer having trailer brakes and a strain gauge assembly affixed to a continuous mounting surface of a unitary mounting block, the trailer towable by a vehicle providing a proportional braking signal, said method comprising:
