| 1. An engine start control device for a hybrid vehicle equipped with an electric motor and an engine with an induction system,
comprising:
a hybrid controller that performs an engine start determination to determine whether the engine should be started while the
electric motor is running;
an acceleration position sensor that detects an acceleration demand of the driver during the engine start determination; and
a start/power generation motor that starts the engine, wherein a pressure in the induction system is controlled based on the
acceleration demand, the hybrid controller determines whether the engine should be started based on the acceleration demand,
the start/power generation motor cranks the engine based on the hybrid controller determination and the hybrid controller
starts the engine by starting a fuel injection a predetermined time after the cranking starts.
