This app uses a Pedal Force Sensor (RLACS282) connected to the VBOX Touch via a Mini Input Module (MIM01) to measure stopping distance from a nominated pedal force to zero.
The user can specify the pedal force at which the test should start, as well as a minimum speed threshold at which the test will start. The screen displays the current vehicle speed, the current pedal force, the braking distance, the MFDD and the average deceleration of the last completed brake stop. The results from each brake stop are automatically recorded to a text file on the SD card, along with a .vbo file that contains all the VBOX data required for post-processing using the ‘Trigger’ plugin in VBOX Test suite.
To use the app, the brake pedal force sensor must be wired into the ‘AN1’ channel of the Mini Input Module that is set into ‘Timed’ mode and with a baud rate of 500 kbit/s, data format of '32-bit float' and a timer value of 10ms. The ‘Voltage_1’ channel must be scaled and offset correctly within the unit, and the response ID must be set to 501.
