When dealing with parameters that are difficult to measure in assembled vehicles, you can use data on the CAN bus to assess vehicle condition and status. Use the Non-Contact CAN Sensor SP7001/SP7002 to monitor a CAN bus without the need for bothersome preparations like fabricating sub-harnesses or modifying cables. Simply remove the sensors when you're finished, without any effect on the vehicle.
In HILS evaluation, a simulation system reproduces CAN signals and other parameters based on the situation being simulated. The motor or inverter is controlled while assessing the condition of its ECU based on CAN data. Motor characteristics and efficiency can be calculated under a variety of anticipated conditions by capturing CAN signals along with data such as inverter output voltage and current, torque, and frequency.
