Abstract
An air flow sensor chip-heating control device and method of a diesel hybrid electric vehicle controls whether an air flow sensor installed in an engine intake system of the diesel hybrid electric vehicle performs a chip-heating operation. Particularly, the air flow sensor chip-heating control device performs a chip heating operation of the air flow sensor based on a result obtained by deciding a driving history of an engine when the vehicle enters into a hybrid mode during driving of the engine.
Claims8
An air flow sensor chip-heating control device of a diesel hybrid electric vehicle, the device comprising:
- a hybrid control unit (HCU) configured to request an engine control unit (ECU) to stop operation of an engine when the diesel hybrid electric vehicle enters into a hybrid operation mode during operation of the engine, and transmit, to the ECU, vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode;
- and
- the ECU configured to decide an 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 determine whether a chip-heating operation of an air flow sensor is performed based on the decision result.
A method of operating an air flow sensor chip-heating control device of a diesel hybrid electric vehicle, comprising the steps of:
- requesting, by a hybrid control unit (HCU), an engine control unit (ECU) to stop operation of an engine when the diesel hybrid electric vehicle enters into a hybrid operation mode during operation of the engine;
- transmitting, to the ECU, vehicle status information when the diesel hybrid electric vehicle enters into the hybrid operation mode;
- deciding an operation history of the engine, which is performed by the ECU 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
- determining whether a chip-heating operation of an air flow sensor is performed based on the step of deciding the operation history of the engine.
