Abstract
A motor assist control apparatus for a hybrid vehicle having an engine and an electric motor includes a first map that executes power-generating operation of the motor from both engine rotational speed and engine load during traveling of the hybrid vehicle. A second map executes driving operation of the electric motor when the load detected by a load detector exceeds a set value during traveling of the hybrid vehicle. A use demand input switch inputs a second map use demand input signal by manual operation. A controller executes both drive and power-generating operations for the motor based on a driving state of the hybrid vehicle and a driving state of the engine. The control apparatus executes a drive operation for the electric motor and switches over use to the second map when a use demand signal is input and when second map use conditions are satisfied. As a result, the motor assist control apparatus can realize smooth acceleration on the basis of selection by a driving person during traveling of the hybrid vehicle. The control apparatus does not require an exclusive map, and can contribute to a simplified control system.
