System for determining that driving of a hybrid vehicle is disabled

A system for determining disablement of driving of a hybrid vehicle, comprising:

• power electronic components having a battery at which DC electricity is stored, an inverter to convert the DC electricity of the battery into AC electricity, and a motor to receive the AC electricity from the inverter and to generate driving torque;
• an engine to burn a fuel so as to generate driving torque, the engine selectively connected to the motor;
• an engine clutch to selectively connect the engine to the motor;
• a transmission connected to the motor to receive at least one of either the driving torque of the motor or the driving torque of the engine;
• a differential apparatus to receive the at least one of either the driving torque of the motor or the driving torque of the engine from the transmission, the differential apparatus to drive a wheel;
• and
• a control portion to control operations of the power electronic components, the engine, and the engine clutch,
• wherein the control portion turns off a system ready indication in a case that neither the driving torque of the motor nor the driving torque of the engine is normally transmitted to the differential apparatus in a state that a system ready is indicated and a vehicle is stopped.

A method for determining disablement of driving of a hybrid vehicle, comprising:

• controlling operations of power electronic components having a battery at which DC electricity is stored, an inverter to convert the DC electricity of the battery into AC electricity, and a motor to receive the AC electricity from the inverter and to generate driving torque;
• controlling operations of an engine configured to burn a fuel so as to generate driving torque, the engine being selectively connected to the motor;
• controlling operating of an engine clutch that selectively connects the engine to the motor;
• determining whether driving of the vehicle is disabled;
• and
• turning off a system ready indication in response to driving of the vehicle being disabled.
