Steering Wheel Transducer
MCL-2
This new type of Steering Wheel Transducer has been designed for a precise
measurement of Steering-moment and Steering angle applied at a Standard
Steering Wheel. All function of the Standard Steering Wheel, including safety
functions (per example airbag etc.) remain100% in operation.

The output signal of the moment transducer is going to be wireless transmitted and captured by a on – board DAQ (Data acquisition device). The within
Steering wheel available on board power, can be as well tapped for powering
the Electronic of MCL-2 components located at the Steering Wheel. Required
adaptors are part of the scope of delivery. By push button control at the DAQ
one can reset the moment signal to Zero. Shunt calibration can be executed
by push button control located at the Steering Transducer. The Steering Angle
is going to be scanned contactless by a external installed Sensor heat and
captured data are transmitted via cable to the on board DAQ. The 2 trace
Signal is, if required, as well available as TTL Signal. Furthermore, the Angle
speed created by a Microcontroller is available at the analogue output of the
DAQ. At the DAQ is as well a Zero adjust of the Steering Angle by push button
control possible.

The DAQ can be delivered on demand with a installed RS-232 (9-pol. Sub-D)
Interface in order to be able to read out Moment and Angle. The RS-232
Interface is due to a internally applied converter converted to a hardware USB
Interface. Because of a driver the hardware USB at the Computer appears as a
virtual COM Interface (VCP)
1
Data are available at a galvanic decoupled CAN-Bus. Set up of the CAN Interface (Identifier and Baud rate) takes place via RS-232 Interface
(USB -> virtual COM).

Optional available: Software to capture data via CAN Interface in order to
visualize values of figures, per example as courses of curves and back up of
data as well as reproduction of data. Driver for VCP Interface and an Excel
Macro for set up of CAN Interface will be delivered.

This Software enable to read data via the supplied CAN-USB Converter and a USB Interface at the PC. Captured
data like Moment, Angle and Angular velocity can be displayed as numerical value or as a course of curve and
stored by just a mouse click. Following data formats are selectable: ASCII; Famos; DasyLab; Signalys-DOS; DIAdem; Remus; DADisp; DAP-Vektor; n-Soft; Flex4.
Stored data can be reloaded and visualized.
