Introduction
The Electronic Throttle Driver Module Kit provides a CompactRIO (cRIO) module for driving
passenger car electronic throttle bodies up to 70mm in diameter. A typical example of electronic
throttle bodies which this module is capable of driving is the Bosch DV-E5 series which range
from 32mm to 68mm in diameter. However, the module is capable of driving most other
electronic throttle bodies within that size range.
The Electronic Throttle Driver Module Kit includes a LabVIEW FPGA VI for controlling two H-
Bridge driver channels independently. Also provided are a set of RT VIs which allow the user to
calibrate the throttle control algorithm in engineering units. The FPGA VI may be used by itself
for driving any small DC motor other than an electronic throttle. However, this manual will focus
on the application of electronic throttle position control. The features included are listed below:
Features:

2-Ch. H-Bridge Drivers for dual electronic throttle control

2-Ch. analog input for throttle position feedback

Short circuit and over-temperature protection with fault reporting

Battery voltage, current sensing and module temperature measurements

LabVIEW FPGA VI for h-bridge control and interface

LabVIEW RT VI for electronic throttle position control

External power supply of 6-32V
