CONTROL APPARATUS FOR HYBRID VEHICLE

摘要

Control apparatuses for hybrid vehicles are disclosed which rapidly decrease the voltage of an inverter following a collision. The control apparatus increases a force of engagement of a clutch when an operating speed of an engine is lower than an operating speed of an electric motor after a collision, and reduces the force of engagement of the clutch when the operating speed of the engine is equal to or higher than the operating speed of the electric motor after the collision. Accordingly, the clutch is placed in an engaged state when the engine applies a load to the electric motor, and is placed in a released state when the operating speed of the electric motor is raised by the engine in the engaged state of the clutch so that the operating speed of the electric motor can be rapidly lowered and a voltage of an inverter can be rapidly lowered.

主权项

1. A control apparatus for a hybrid vehicle provided with an engine, an electric motor, a clutch disposed in a power transmitting path between the engine and the electric motor, and an inverter for supplying electric energy from an electric energy storage device to said electric motor, and the inverter being configured to be discharged upon a collision of the hybrid vehicle, wherein:
the control apparatus comprises a processor and a memory storing a computer readable and executable instruction set which is executed by the processor to:
determine when a collision of said hybrid vehicle has occurred;increase a force of engagement of said clutch when an operating speed of said engine is lower than an operating speed of said electric motor after the collision of the hybrid vehicle occurs; andreduce the force of engagement of said clutch when the operating speed of said engine is equal to or higher than the operating speed of said electric motor after the collision of the hybrid vehicle occurs.
