Abstract
Official abstract text for this publication.
A control device for a vehicle, the vehicle including: a battery; a first rotary electric machine coupled to an axle; a second rotary electric machine coupled to an internal combustion engine; a first power conversion circuit; a second power conversion circuit; a capacitor connected between the battery and connection portions connecting the first power conversion circuit and the second power conversion circuit in parallel; and a switching unit connected between the battery and the capacitor, the control device executing discharge control when a collision of the vehicle is predicted, and the discharge control includes: opening the switching unit to interrupt the power supply from the battery; stopping rotation of the first rotary electric machine if the first rotary electric machine is rotating; and discharging the electric charge stored in the capacitor.
First claim
Opening claim text (preview).
What is claimed is: 1. A control device for a vehicle, wherein the vehicle includes: an internal combustion engine; a battery; a first rotary electric machine coupled to an axle; a second rotary electric machine coupled to the internal combustion engine; a first power conversion circuit configured to convert power between the battery and the first rotary electric machine; a second power conversion circuit configured to convert power between the battery and the second rotary electric machine and connected in parallel with the first power conversion circuit at connection portions; a capacitor connected between the battery and the connection portions to store an electric charge; and a switching unit connected between the battery and the capacitor and configured to interrupt power supply from the battery, the control device is configured to execute discharge control when a collision of the vehicle is predicted, and the discharge control includes: opening the switching unit to interrupt the power supply from the battery; stopping rotation of the first rotary electric machine if the first rotary electric machine is rotating; and discharging the electric charge stored in the capacitor. 2. The control device for a vehicle according to claim 1 , wherein in discharging the electric charge stored in the capacitor, the electric charge is supplied to the second rotary electric machine. 3. The control device for a vehicle according to claim 1 , wherein when the collision of the vehicle is avoided after executing the discharge control, the control device ends the discharge control. 4. The control device for a vehicle according to claim 1 , wherein the vehicle further includes a parking mechanism configured to lock rotation of the axle, and upon the collision of the vehicle, the control device controls the parking mechanism to lock the rotation of the axle in order for the first rotary electric machine coupled to the axle not to rotate. 5. The control device for a vehicle according to claim 1 , wherein the vehicle further includes a clutch configured to couple the first rotary electric machine to the internal combustion engine when the clutch engages, the discharge control further includes stopping the internal combustion engine, and upon the collision of the vehicle, the control device controls the clutch to engage in order for the first rotary eclectic machine not to rotate.
