A 24-bit resolution data acquisition system with
eight channels for analogue and digital signals (QuantumX
MX840, HBM, Germany) were installed to measure the signals
from driving axles torque and fuel consumption. An analogue
input channel with a sampling rate of 19.2 kHz per channel was
used to measure the signal from the axle torque, and a digital input
channel with a sampling rate of 1 MHz per channel was used to
measure the rising edge signals for the fuel consumption. The
measured signals were transmitted to a lab notebook
with a Firewire, and a measurement program was
developed using Catman (version 3.1, HBM, Germany)
to link the data acquisition system. The data acquisition
system, placed inside a removable fixture, was attached
next to the driver’s seat.
