System and Method for Measurement and Evaluation of Brake Pedal Performance

摘要

Linear brake pedal travel measurements are provided using a diagnostic unit with at least two linear measurement devices. The at least two linear measurement devices are offset in at least a vertical direction from a face of the brake pedal lever, and therefore directly measure non-linear pedal travel values. Thus, in certain embodiments, the system is further configured to convert the non-linear pedal travel measurements received from each of the at least two linear measurement devices to a linear brake pedal travel value corresponding to an operated position of the brake pedal lever. The resulting linear brake pedal travel information may then be used to evaluate brake pedal performance or measure customer brake feeling in an objective and reproducible way.

1. A system for measurement and evaluation of brake pedal performance for a vehicle comprising:
a diagnostic unit having a processor coupled to a memory; and at least two linear measurement devices in electrical communication with the diagnostic unit, wherein the at least two linear measurement devices are offset in at least a vertical direction from a face of the brake pedal lever, wherein the at least two linear measurement devices are each configured to provide, in response to an operation of the brake pedal lever from an initial position to a first operated position, a signal corresponding to a non-linear pedal travel measurement of the brake pedal lever resulting from said operation, and wherein the processor is configured to convert the non-linear pedal travel measurements received from each of the at least two linear measurement devices to a linear brake pedal travel value corresponding to the first operated position.
