Abstract
A pedal travel audit assembly adapted for measuring the applied force to and resultant pedal travel of a brake pedal includes first and second sensors and an electronic control unit, wherein the second sensor is configured to wirelessly detect the relative distance between the pedal and a remaining structure spaced from and unsupportive of the pedal, and the electronic control unit is configured to cause an output relative to the distance to be generated.
Claims3
A method of auditing a brake system of a vehicle, wherein said vehicle includes a translatable brake pedal, and a remaining fixed structure spaced from the pedal, said method comprising the steps of:
- a. securing first and second sensors in a fixed position relative to the pedal and spacing the second sensor from the structure, wherein the first sensor is configured to measure a force applied to the pedal, and the second sensor is configured to detect a relative distance between the pedal and structure;
- b. applying a plurality of differing forces to the first sensor, wherein each force causes the pedal to translate a correlative differing distance, so as to determine a plurality of correlative distances, and force/distance combinations;
- c. measuring said plurality of forces with the first sensor, and detecting said plurality of correlative distances with the second sensor;
- d. generating a trend based on the pluralities of forces and distances;
- and
- e. comparing the trend to a reference, so as to determine a compliance status.
