1. A system, comprising:
- a first diagnostic computing device;
a second diagnostic computing device configured to be in communication with the first diagnostic computing device and a computing device of a vehicle, the second diagnostic computing device configured to communicate brake pedal position information to the first diagnostic computing device; and
a display in communication with the first diagnostic computing device, the display configured to indicate a current position of a brake pedal of the vehicle relative to a first predetermined range of brake pedal positions and relative to a second predetermined range of brake pedal positions based on the brake pedal position information, wherein the first predetermined range of brake pedal positions and the second predetermined range of brake pedal positions are non-overlapping ranges between a fully unactuated position and a fully actuated position.

Abstract
According to one aspect, a method includes receiving, in a dynamometer, brake pedal position information. The brake pedal position information indicates a position of a brake pedal operatively coupled to a vehicle. The method also includes displaying, via a display in communication with the dynamometer, an indication of the position of the brake pedal based on the brake pedal position information. The method further includes determining a brake force generated via a brake of the vehicle when the position of the brake pedal is within a predetermined range of brake pedal positions.

8. A method, comprising:
-
receiving, in a dynamometer, brake pedal position information, the brake pedal position information indicating a current position of a brake pedal operatively coupled to a vehicle; displaying, via a display in communication with the dynamometer, an image indicating a first predetermined range of brake pedal positions, wherein the first predetermined range of brake pedal positions and the second predetermined range of brake pedal positions are non-overlapping ranges between a fully unactuated brake position and a fully actuated brake position; displaying, via the display, an indication of the current position of the brake pedal based on the brake pedal position information, wherein the indication is visually associated with the image to indicate the current position of the brake pedal relative to the first predetermined range of brake pedal positions and the second predetermined range of brake pedal positions; updating the display based on brake pedal position information as the current position of the brake pedal is adjusted; and determining a brake force generated via a brake of the vehicle when the current position of the brake pedal is within the first predetermined range of brake pedal positions and outside of the second predetermined range of brake pedal positions. - View Dependent Claims (9, 10, 11, 12, 13)
