An air flow sensor chip-heating control device of a diesel hybrid electric vehicle, the device comprising: a) a hybrid control unit configured a1) to request an engine control unit to stop operation of an engine when the diesel hybrid electric vehicle enters into a hybrid operation mode during operation of the engine, and a2) to transmit, to the ECU, vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode; and b) the ECU being configured b1) to decide on operation history of the engine based on the vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode, which is transmitted from the HCU, and b2) to determine whether a chip-heating operation of an air flow sensor is performed based on the decision result; b3) the operation history of the engine being whether the engine is driven to an extent where the chip-heating function of the air flow sensor is required, and b4) the vehicle status information including information on an engine coolant temperature, information on a vehicle speed, information on an accumulation time when the vehicle speed is not less than a first reference value, information on revolutions per minute of the engine, and information on an accumulation time when the RPM of the engine is not less than a second reference value. a) a hybrid control unit configured a1) to request an engine control unit to stop operation of an engine when the diesel hybrid electric vehicle enters into a hybrid operation mode during operation of the engine, and a2) to transmit, to the ECU, vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode; and a1) to request an engine control unit to stop operation of an engine when the diesel hybrid electric vehicle enters into a hybrid operation mode during operation of the engine, and a2) to transmit, to the ECU, vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode; and b) the ECU being configured b1) to decide on operation history of the engine based on the vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode, which is transmitted from the HCU, and b2) to determine whether a chip-heating operation of an air flow sensor is performed based on the decision result; b3) the operation history of the engine being whether the engine is driven to an extent where the chip-heating function of the air flow sensor is required, and b4) the vehicle status information including information on an engine coolant temperature, information on a vehicle speed, information on an accumulation time when the vehicle speed is not less than a first reference value, information on revolutions per minute of the engine, and information on an accumulation time when the RPM of the engine is not less than a second reference value. b1) to decide on operation history of the engine based on the vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode, which is transmitted from the HCU, and b2) to determine whether a chip-heating operation of an air flow sensor is performed based on the decision result; b3) the operation history of the engine being whether the engine is driven to an extent where the chip-heating function of the air flow sensor is required, and b4) the vehicle status information including information on an engine coolant temperature, information on a vehicle speed, information on an accumulation time when the vehicle speed is not less than a first reference value, information on revolutions per minute of the engine, and information on an accumulation time when the RPM of the engine is not less than a second reference value.
