<P>PROBLEM TO BE SOLVED: To provide a method of controlling a hybrid vehicle, preventing abnormal operations and damage to an automatic transmission due to reverse rotation of the input shaft of the automatic transmission and achieving smooth pre-stop gearshift by appropriately controlling reverse torque exerted in the input shaft of the automatic transmission when performing the pre-stop gearshift. <P>SOLUTION: The method of controlling a hybrid vehicle comprises: a step of pre-gearshift control that reduces reverse torque of the motor generator to the level of a first step, when a pre-stop gearshift order is generated in regenerative braking, between a point of time where the gearshift order is generated and a point of time where the actual gearshift is started; a step of mid-gearshift control that reduces the reverse torque of the motor generator to the level of a second step, which is smaller than the level of the first step, from a point of time where the actual gearshift starts to be performed by the gearshift order to a point of time where engaging components of the automatic transmission are completely interlocked; and a step of post-gearshift control that increases the reverse torque of the motor generator after the interlocking is finished. <P>COPYRIGHT: (C)2010,JPO&INPIT |
