Title:
A control device of a hybrid car
Document Type and Number:
Japanese Patent JP6024482
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable communication delay time between ECUs to be determined.SOLUTION: An HV-ECU 24, when predetermined conditions are established, acquires engine rotation speed Ne and also acquires MG rotation speed Nm from a MG-ECU 26, in control timing of the HV-ECU 24, and calculates MG rotation acceleration Am on the basis of a difference between the latest value and the previous value of the MG rotation speed Nm. The HV-ECU estimates (calculates) communication delay time T on the basis of the engine rotation speed Ne, the MG rotation speed Nm and the MG rotation acceleration Am, in the control timing of the HV-ECU 24 by using a mathematical formula defining correlation among the engine rotation speed Ne, the MG rotation speed Nm acquired from the MG-ECU 26, the MG rotation acceleration Am determined from the MG rotation speed Nm and the communication delay time T (delay time of control timing of the HV-ECU 24 with respect to the control timing of the MG-ECU 26), in the control timing of the HV-ECU 24.
