Wheels turn to telemetry data

Edited by the Engineeringtalk editorial team Sep 12, 2005

The range of telemetry steering wheels from Caesar DataSystems enables measurement of angle, angular speed, torque and tri-axial acceleration.

For research and development into steering, handling and comfort of cars and trucks, especially those involving the introduction or refinement of ESPs (electronic stability programs), an accurate measure of steering wheel angle and torque is required.

The driver's steering input, applied force and movement can be measured and correlated with other vehicle parameters such as speed, acceleration, heading, pitch and roll.

The range of telemetry steering wheels from Caesar DataSystems enables measurement of angle, angular speed, torque and tri-axial acceleration.

The power for the sensors and data from the steering wheel are both coupled wirelessly, ensuring normal steering movements.

The digital decoder and receiver unit provides outputs suitable for recording on standard data acquisition systems.

Two new additions to the range are now available.

The Model CLW steering angle controller allows the maximum angle of the steering wheel, left and right independently, to be set to predefined limits during testing manoeuvres.

The hydraulic braking system accepts signals from a measurement steering wheel or external CANbus data message.

Advanced safety features ensure the steering limits can be over ridden under specific operating conditions.

The Model CLZ steering wheel is a full measurement steering wheel system that can be integrated into the vehicle steering column.

Auto zero and calibration, simultaneous dual-range outputs for angle and torque, and wireless transmission of data and power are standard features.

Data can be output via analogue, digital and CANbus interfaces.
