Wheel Force Sensor (WFS)
The Wheel Force Sensor measures the 6 force components of the wheel as near as possible to realistic driving conditions. The sensor design achieves both a low weight and high stiffness. It is designed to provide high quality measurement data under any type of driving conditions.

Unique Features of WFS
A&D Model Based Sensor (MBS) approach-

  • High Speed A/D converts strain gauge output directly in the sensor to digital signals
  • Digital real time processing using a sensor model
  • Extracts 6 independent components force and moment
  • Minimum cross talk effects beyond conventional analog circuit amplification

Main Technical Data

  • Standard Range: Fz 24kN, My 4kNm
  • Sensitivity: 1/4000 for forces and 1/2500 for moments.
  • Total Error: lower than 0.1%
  • Laser Ground Sensor

The laser Ground sensor uses laser sensors to measure as ground speed and hight and angle of the vehicles wheel.
The Laser Ground Sensor (LGS) consists of 2 Laser Doppler Velocimeters (LDV) and 3 Laser Distance Sensors (LDS). The LDVs measure ground speed in two directions and tire rotation in a lateral direction. The 3 LDSs measure the distance from the ground to determine the changes in wheel height during the drive. Slip angle (output from the ground speed data), camber angle, pitch angle, roll angle (outputs from the distance data) can be obtained from DSP (Digital Signal Processor) calculations.

Unique Features of LGS:

  • IP65 waterproof rating
  • LDS can be used on days with bright skies by attaching a filter
  • LDV is operable at speeds starting at 0km/h
  • Can be independently attached to a standard wheel
  • Can be used in various combinations with A&D vehicle measurement systems
  • Data can be stored in a Micro SD card inside the controler
  • CAN interface for digital signal logging

Wheel Position Sensor
The Wheel Position Sensor measures the change of the wheel position in 6 components.
The wheel movement is measured in relation to the vehicle body using an original A&D model. Data collected from 5 individual sensors is converted into the following 6 values: X displacement: Vehicle longditunal direction Y displacement: Vehicle lateral direction Z displacement: Gravity direction Ax: Angle of gravity direction and wheel diameter direction Ay: Wheel rotation angle Az: Angle of vehicle movement direction and tire direction.

Unique Features of WFS:

  • High resolution 17 bit rotary encoder
  • Absolute value measurement system – no need for calibration
  • Attachable to a standard wheel
  • IP65 waterproof rating
  • Measured data is stored in Micro SD card
  • CAN Interface for digital signal logging
