Abstract
Official abstract text for this publication.
A control apparatus for a vehicle is configured to be applied to a hybrid vehicle that includes an electric motor and an engine that are coupled to a drive wheel. The control apparatus includes a transmission mechanism and a torque processor. The transmission mechanism is to be provided between the engine and the drive wheel, and configured to switch between a plurality of fixed gear ratios to perform a shift. The torque processor is configured to temporarily decrease a torque of the electric motor and a torque of the engine upon execution of an upshift of the transmission mechanism, and configured to decrease, before the execution of the upshift of the transmission mechanism, a proportion of the torque of the electric motor to a drive wheel torque of the drive wheel as compared with a recent proportion of the torque of the electric motor to the drive wheel torque.

1 . A control apparatus for a vehicle, the control apparatus being configured to be applied to a hybrid vehicle that includes an electric motor, an engine, and a drive wheel, the electric motor and the engine being coupled to the drive wheel, the control apparatus comprising: a transmission mechanism to be provided between the engine and the drive wheel, and configured to switch between a plurality of fixed gear ratios to perform a shift; and a torque processor configured to temporarily decrease a torque of the electric motor and a torque of the engine upon execution of an upshift of the transmission mechanism, and configured to decrease, before the execution of the upshift of the transmission mechanism, a proportion of the torque of the electric motor to a drive wheel torque of the drive wheel to be transmitted from the transmission mechanism to the drive wheel as compared with a recent proportion of the torque of the electric motor to the drive wheel torque. 2 . The control apparatus for the vehicle according to claim 1 , wherein the torque processor is configured to decrease, before the execution of the upshift of the transmission mechanism, the proportion of the torque of the electric motor to the drive wheel torque as compared with the recent proportion of the torque of the electric motor to the drive wheel torque by decreasing the torque of the electric motor. 3 . The control apparatus for the vehicle according to claim 1 , wherein the torque processor is configured to increase, before the execution of the upshift of the transmission mechanism, a proportion of the torque of the engine to the drive wheel torque as compared with a recent proportion of the torque of the engine to the drive wheel torque. 4 . The control apparatus for the vehicle according to claim 2 , wherein the torque processor is configured to increase, before the execution of the upshift of the transmission mechanism, a proportion of the torque of the engine to the drive wheel torque as compared with a recent proportion of the torque of the engine to the drive wheel torque. 5 . The control apparatus for the vehicle according to claim 3 , wherein the torque processor is configured to increase, before the execution of the upshift of the transmission mechanism, the proportion of the torque of the engine to the drive wheel torque as compared with the recent proportion of the torque of the engine to the drive wheel torque by increasing the torque of the engine. 6 . The control apparatus for the vehicle according to claim 4 , wherein the torque processor is configured to increase, before the execution of the upshift of the transmission mechanism, the proportion of the torque of the engine to the drive wheel torque as compared with the recent proportion of the torque of the engine to the drive wheel torque by increasing the torque of the engine. 7 . The control apparatus for the vehicle according to claim 3 , wherein the torque processor is configured to keep, before the execution of the upshift of the transmission mechanism, the drive wheel torque constant by decreasing the proportion of the torque of the electric motor to the drive wheel torque and by increasing the proportion of the torque of the engine to the drive wheel torque. 8 . The control apparatus for the vehicle according to claim 4 , wherein the torque processor is configured to keep, before the execution of the upshift of the transmission mechanism, the drive wheel torque constant by decreasing the proportion of the torque of the electric motor to the drive wheel torque and by increasing the proportion of the torque of the engine to the drive wheel torque. 9 . The control apparatus for the vehicle according to claim 5 , wherein the torque processor is configured to keep, before the execution of the upshift of the transmission mechanism, the drive wheel torque constant by decreasing the proportion of the torque of the electric motor to the drive wheel torque and by increasing the proportion of the torque of the engine to the drive wheel torque. 10 . The control apparatus for the vehicle according to claim 6 , wherein the torque processor is configured to keep, before the execution of the upshift of the transmission mechanism, the drive wheel torque constant by decreasing the proportion of the torque of the electric motor to the drive wheel torque and by increasing the proportion of the torque of the engine to the drive wheel torque. 11 . A control apparatus for a vehicle, the control apparatus being configured to be applied to a hybrid vehicle that includes an electric motor, an engine and a drive wheel, the electric motor and the engine being coupled to the drive wheel, the control apparatus comprising: a transmission mechanism to be provided between the engine and the drive wheel, and configured to switch between a plurality of fixed gear ratios to perform a shift; and circuitry configured to decrease, before execution of an upshift of the transmission mechanism, a proportion of a torque of the electric motor to a drive wheel torque of the drive wheel to be transmitted from the transmission mechanism to the drive wheel as compared with a recent proportion of the torque of the electric motor to the drive wheel torque.
