5.2.1. Brake trigger switch
(Available to purchase as an option)
The brake trigger is designed to be mounted on the brake pedal or the accelerator pedal and gives an
indication when the pedal is pressed. The normal method of fixing is via rubber bands. The brake trigger
can be used during a brake stop to determine the speed at which the brake pedal was pressed, and the
braking distance from this point can be viewed. This switch can be connected directly to an input of the
data acquisition system or to the DS-VGPS-HS. The DS-VGPS-HS will recognize the exact time of the
switching point. A serial command with this time information will be transmitted to the data acquisition
unit. DewesoftX® displays this event as a separate channel. This channel can be used during post
processing to calculate the brake distance.
