ULTRA-THIN LOW COST PEDAL FORCE TRANSDUCER
Pedal Force transducers that are currently available in the market have some disadvantages such as their price and relative size compared to the space between the pedal and the driver´s footwear. As consequence of the last condition, the pedal push action is hindered and unsafe situations are generated over vehicle driving. The use of current load cells dramatically reduces driver's comfort and leads to difficulties during the performance of static and dynamic tests. In addition, instrumentation issues arise, such as difficult assembly caused by pedal geometry differences.
A device design which uses ultra-thin force sensors is proposed. These sensors are approximately 0.2 millimeter thick. These sensors are included inside a two-sheet package. Those sheets are parallel to the pedal. The lower sheet has contact with the pedal and the upper one with the driver's footwear, which must release contact if the user is not pushing the pedal. The upper sheet is the mean of force transmission to the ultra-thin sensors regardless the footwear's sole marks. This device has elastic straps in order to attach it to the pedal, making it adaptable to different pedal shapes or sizes.
Parts description of the New Approach:
1. Elastic adjustment band.
3. Upper sheet - Surface making contact with the footwear, it is flexible.
4. Lower sheet - Surface making contact with the pedal.
