The CW-311NG wheel speed simulation simulates the active current-modulated wheel speed sensors used in the automotive industry. The CW-311NG can simulate a speed range from 0.1 Hz to 5000 Hz in three different operating modes. It is used, for example, in hardware-in-the-loop (HiL) test environments for control units.
The CW-311NG receives real-time and control data via the integrated CAN bus and uses it to generate signals from wheel speed sensors. The simulation data can be transferred to the CW-311NG from any source via the CAN interface, for example from an automation computer that plays back a realistic track model.
The wheel speed information is output via a current interface. It is possible to simulate sensors from different manufacturers. Various parameters such as air gap reserve error, direction of rotation, installation position signal and more can be dynamically influenced conveniently via a web interface for configuration.
