L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: TERMINALS OF ECU

NOTICE:
Do not measure the voltage or waveform directly at the sealed side of the inverter with converter assembly connector. Doing so may damage the connector because the connector is waterproof.

2. Oscilloscope waveforms

HINT
Oscilloscope waveform samples are provided here for informational purposes. Noise and fluttering waveforms have been omitted.

(a) Waveform 1 (motor resolver signal)









HINT
Pulse cycle A becomes shorter as the rotor speed increases.

(b) Waveform 2 (MG ECU communication request signal)









(c) Waveform 3 (communication signal from hybrid vehicle control ECU to MG ECU)









HINT
The waveform will vary depending on the content of the digital communication (digital signal).

(d) Waveform 4 (GI signal)









HINT
The pulse cycle becomes shorter as the engine speed increases.

(e) Waveform 5 (generator resolver signal)









HINT
Pulse cycle A becomes shorter as the rotor speed increases.

(f) Waveform 6 (communication signal from MG ECU to hybrid vehicle control ECU)









HINT
The waveform will vary depending on the content of the digital communication (digital signal).
