Control apparatus for vehicle
In the case where a connector of a charging cable is connected to a charging connector provided on a hybrid vehicle, a connector signal CNCT indicating that the connector of the charging cable is connected to the charging connector provided on the hybrid vehicle is input to a power supply ECU and an HV_ECU having an operating frequency higher than that of the power supply ECU. When the connector signal CNCT is input, the power supply ECU activates the HV_ECU. The HV_ECU controls the electrical system of the hybrid vehicle so as to charge a battery pack. The HV_ECU stops the charging when the input of the connector signal CNCT is stopped during charging of the battery pack.
1. A control apparatus for a vehicle provided with an electrical system having a battery storing electric power supplied from an external power supply through an EVSE, said control apparatus comprising:
a first control unit that receives an input of a connector signal indicating that said EVSE is connected to the vehicle when said EVSE is connected to the vehicle; and
a second control unit that has an operating frequency higher than an operating frequency of said first control unit and receives an input of said connector signal when said EVSE is connected to the vehicle, wherein
said first control unit activates said second control unit when said connector signal is input, and
said second control unit
controls, in an activated state, said electrical system to charge said battery, and
controls said electrical system to stop charging said battery when the input of said connector signal is stopped.
2. The control apparatus for a vehicle according to claim 1 , wherein
said second control unit
transmits, during charging of said battery, a charging signal to said first control unit indicating that said battery is being charged, and
stops transmitting said charging signal when charging of said battery is stopped, and
said first control unit deactivates said second control unit when said charging signal is stopped.
3. The control apparatus for a vehicle according to claim 2 , wherein
said first control unit
activates said second control unit by using an IG signal to output an IG_ON command, and
deactivates said second control unit by using the IG signal to output an IG_OFF command.
4. The control apparatus for a vehicle according to claim 1 , wherein
said second control unit is an HV_ECU controlling charging of said battery, and
said first control unit is a power supply ECU controlling activation and deactivation of said HV_ECU.
5. The control apparatus for a vehicle according to claim 1 , wherein said first control unit and said second control unit are mounted in said vehicle.
6. The control apparatus for a vehicle according to claim 1 , wherein said vehicle is a plug-in hybrid vehicle.
