A control apparatus for a hybrid vehicle having a dynamotor which operates as a motor for assisting the output of an internal combustion engine and which operates as a generator for regenerating the running energy of the vehicle. The control apparatus, in accordance with operating conditions of the vehicle, controls an assist operation for supplying electric power from a storage device to the dynamotor and a regenerative operation for charging the storage device by the generated power of the dynamotor, and determines an acceleration mode for performing an assist operation or a cruising mode for selectively performing the assist operation and a regenerative operation, in accordance with an engine rotational speed and a throttle valve opening degree, or a vehicle speed of the vehicle and the throttle valve opening degree.

[ What is claimed is:] [1.]1. A control apparatus for a hybrid vehicle having an internal combustion engine and a dynamotor as drive sources of said vehicle, said dynamotor operating as a motor for assisting the output of said internal combustion engine and operating as a generator for regenerating running energy of said vehicle, said apparatus comprising:control means responsive to operating conditions of said vehicle for controlling an assist operation for supplying electric power from a storage device to said dynamotor and a regenerative operation for charging said storage device by the generated power of said dynamotor; anddetermination means for determining that the operating condition of said vehicle is in one of a plurality of operation modes including at least an acceleration mode for performing the assist operation and a cruising mode for selectively performing the assist operation and the regenerative operation,wherein said determination means determines that the operating condition of said vehicle is in the acceleration mode when a throttle valve opening degree of said internal combustion engine has exceeded an acceleration mode start threshold value corresponding to one of an engine rotational speed and a vehicle speed and determines that the operating condition of said vehicle is in the cruising mode when the throttle valve opening degree has fallen below an acceleration mode end threshold value which is less than said acceleration mode start threshold value and which corresponds to one of the engine rotational speed and the vehicle speed.
