Embodiment Construction
[0042] figure 1 It is a schematic diagram of the electromagnetic compatibility test scene of the vehicle controller. The test process is carried out in an anechoic chamber. The vehicle controller is connected to the load device through an adapter. The adapter is an independent component, which is composed of a wire harness and connectors at both ends connected by the wire harness, and the connectors at both ends are adapted to the connectors of the load device and the vehicle controller respectively. In this way, when the load device is faced with a vehicle controller that does not match the connector, the matching problem can be solved by customizing the corresponding adapter. Compared with re-developing the load device, this method is undoubtedly a preferred method.
[0043] The load device outputs an electrical signal through the CAN bus, converts it into an optical signal through the optical bridge, transmits it to the electric wave anechoic chamber through the optical f...
