Abstract

A vehicle control apparatus mounted on a vehicle includes: a first starting system provided with a first electric motor coupled to an engine, and a first power storage coupled to the first electric motor; a second starting system provided with a second electric motor coupled to the engine, and a second power storage coupled to the second electric motor; and an engine controller that stops the engine based on a stop condition and restarts the engine using the first starting system, based on a start condition. When an abnormality occurs in the first starting system in a state where the engine has been stopped based on the stop condition, the engine controller restarts the engine using the second starting system.

First claim

1 . A vehicle control apparatus mounted on a vehicle, the vehicle control apparatus comprising:
a first starting system provided with a first electric motor coupled to an engine, and a first power storage coupled to the first electric motor; a second starting system provided with a second electric motor coupled to the engine, and a second power storage coupled to the second electric motor; and an engine controller that stops the engine based on a stop condition and restarts the engine using the first starting system, based on a start condition, wherein when an abnormality occurs in the first starting system in a state where the engine has been stopped based on the stop condition, the engine controller restarts the engine using the second starting system.

2 . The vehicle control apparatus according to claim 1 , wherein when an abnormality occurs in the first starting system, the engine controller restarts the engine using the second starting system before the start condition is established.

3 . The vehicle control apparatus according to claim 1 , wherein the engine controller prohibits stop of the engine based on the stop condition when the engine is restarted using the second starting system.

4 . The vehicle control apparatus according to claim 2 , wherein the engine controller prohibits stop of the engine based on the stop condition when the engine is restarted using the second starting system.

5 . The vehicle control apparatus according to claim 1 , further comprising a switch for switching between a conductive state and a cut-off state, the conductive state involving coupling of the first electric motor and the first power storage are coupled, and a cut-off state involving separation of the first electric motor and the first power storage,
wherein when an abnormality occurs in the first starting system, the engine is restarted by using the second starting system after a cut-off signal for switching the switch to the cut-off state has been output.

6 . The vehicle control apparatus according to claim 2 , further comprising a switch for switching between a conductive state and a cut-off state, the conductive state involving coupling of the first electric motor and the first power storage are coupled, and a cut-off state involving separation of the first electric motor and the first power storage,
wherein when an abnormality occurs in the first starting system, the engine is restarted by using the second starting system after a cut-off signal for switching the switch to the cut-off state has been output.

7 . The vehicle control apparatus according to claim 3 , further comprising a switch for switching between a conductive state and a cut-off state, the conductive state involving coupling of the first electric motor and the first power storage are coupled, and a cut-off state involving separation of the first electric motor and the first power storage,
wherein when an abnormality occurs in the first starting system, the engine is restarted by using the second starting system after a cut-off signal for switching the switch to the cut-off state has been output.

8 . The vehicle control apparatus according to claim 4 , further comprising a switch for switching between a conductive state and a cut-off state, the conductive state involving coupling of the first electric motor and the first power storage are coupled, and a cut-off state involving separation of the first electric motor and the first power storage,
wherein when an abnormality occurs in the first starting system, the engine is restarted by using the second starting system after a cut-off signal for switching the switch to the cut-off state has been output.

9 . The vehicle control apparatus according to claim 5 , wherein the switch is provided in a conduction path that couples a positive electrode terminal of the first power storage and a positive electrode terminal of the second power storage, or in a conduction path that couples a negative electrode terminal of the first power storage and a negative electrode terminal of the second power storage.

10 . The vehicle control apparatus according to claim 6 , wherein the switch is provided in a conduction path that couples a positive electrode terminal of the first power storage and a positive electrode terminal of the second power storage, or in a conduction path that couples a negative electrode terminal of the first power storage and a negative electrode terminal of the second power storage.

11 . The vehicle control apparatus according to claim 7 , wherein the switch is provided in a conduction path that couples a positive electrode terminal of the first power storage and a positive electrode terminal of the second power storage, or in a conduction path that couples a negative electrode terminal of the first power storage and a negative electrode terminal of the second power storage.

12 . The vehicle control apparatus according to claim 8 , wherein the switch is provided in a conduction path that couples a positive electrode terminal of the first power storage and a positive electrode terminal of the second power storage, or in a conduction path that couples a negative electrode terminal of the first power storage and a negative electrode terminal of the second power storage.
