Vehicle Stability Test System Based on VBOX

The VBOX handling stability test system mainly consists of a VBOX dual-antenna data acquisition system, an LED display, a gyroscope and a steering wheel force sensor. It is suitable for vehicle handling stability tests such as steering returnability and steady-state circular tests. Measured parameters include sideslip angle, roll angle, pitch angle, three-axis acceleration, three-axis angular velocity, torque, steering angle and steering angle rate.

Steering Wheel Sensor RLSTSENSOR

The RLSTSENSOR series is designed for steering wheels of modern vehicles such as passenger cars and multipurpose vehicles. The introduction of new driver assistance systems demands better-performing test equipment, fully meeting the needs of modern automotive engineering. Reduced size and weight provide higher dynamics and increased resolution without compromising steering wheel functions (airbag) or control elements. For maximum safety, the sensor has a high breakaway torque. It is mounted between the steering wheel and the steering column. For versatility, the sensor can be fitted with interchangeable adapters for connection to the steering shaft drive. It also has a switch for resetting torque and angle. The offset is stored and remains available after power loss or restart. Via the CAN bus, the output can be set to zero at any point. Calibration data is stored in the sensor element, allowing users to replace the sensor element as needed.
