<P>PROBLEM TO BE SOLVED: To provide a control method for a hybrid electric vehicle, allowing a fuel cut in a wide section and removal of a shock at that time. <P>SOLUTION: This control method includes: a stage wherein an ECU confirms whether the fuel cut of an engine is possible or not when entering a fuel cut state and performs entry preparation, and wherein an HCU transfers and inputs a fuel cut permission signal to the preparation-completed ECU at that time to execute the fuel cut simultaneously with the entry into the fuel cut; a stage for determining fuel cut release according to a condition of a transmission gear ratio of the vehicle, and transferring a fuel cut release signal to the ECU when the gear ratio reaches a control value of a specific gear ratio to release the fuel cut; a stage wherein the ECU having received the fuel cut release signal executes an engine restart; and a stage wherein the HCU executes reaction force control operating opposite to engine torque by use of a motor simultaneously with the restart of the engine in time of the engine restart to perform control such that torque transmitted to a CVT is as smoothly as possible input. <P>COPYRIGHT: (C)2009,JPO&INPIT |
