The purpose of this study is; to develop a
system that can detect road disturbances and can warn the driver. For this
purpose, a measurement method which tracking as a 3-axis of the road situation
with a semiconductor MEMS-based accelerometer has been developed to be used to
detect vehicle vibration and drive conditions which has a serious effect on the
driving quality of the road. With the developed measuring system, road wear and
tear can be successfully reported. Thanks to the
improved system, the driver can also be warned by detecting vehicle suspension
damage. In addition, a driver performance report may be drawn up under the
project that is very important for fleet and service owners (universities,
municipalities and other similar public and corporate entities). Thus, the
damage caused by the bad use of the vehicles can be reduced to the minimum; the
operating costs can be reduced.

The sensor on the measurement card developed for this
purpose is placed at the lower control arm portion point of the vehicle to be
used in the test drives (Renault Thalia II/Symbol brand 2012 model). A testing road
with a length of 135 meters was constructed and test runs were carried out at
different speeds (10km/h, 20 km/h, 30 km/h, 40 km/h and 50 km/h). 7 bumps with
varying dimensions were placed on the created road route at intervals of 5
meters. The obtained data were recorded on the SD card and then analyzed in the
Matlab program by filtering it from the noise. A total of 2099 data were
analyzed. As a result, driver performances can be categorized successfully
(Normal, Medium, Bad, Very Bad, Very Very Bad) for each test drive according to
the speed and condition of the road bumps. Sound and light stimulation of the
driver when the bulge and the pit are entered in the test runs repeated in the
result of the determined threshold acceleration value after the reference
driving has also been successfully achieved.
