Power-assisted increases the output torque of the engine to the engine.
7. the control method of finished of hybrid vehicle as claimed in claim 6, which is characterized in that described according to the gradient
The auxiliary-motor that value controls the hybrid vehicle switches between power generation mode or output assistant mode includes:
If the value of slope is controlled the auxiliary-motor and is run with the power generation mode less than the first setting value P1；
If the value of slope is more than or equal to the first setting value P1, the defeated of the auxiliary-motor is obtained according to the value of slope
Power-assisted grade out, and the power-assisted that the auxiliary-motor exports the grade is controlled, so that the output torque of the engine increases and institute
State the corresponding torque of output power-assisted grade.
8. the control method of finished of hybrid vehicle as claimed in claim 7, which is characterized in that
If the value of slope is more than or equal to the first setting value P1 and less than the second setting value P2, the auxiliary-motor is controlled
The first estate power-assisted is exported, so that the output torque of the engine increases by the first torque N1；
If the value of slope is more than or equal to the second setting value P2 and is less than third setting value P3, the auxiliary-motor is controlled
The second grade power-assisted is exported, so that the output torque of the engine increases by the second torque N2, wherein N2 > N1；
If the value of slope is more than or equal to the third setting value P3, the auxiliary-motor output tertiary gradient power-assisted is controlled,
So that the output torque of the engine increases third torque N3, wherein N3 > N2.
9. the control method of finished of the hybrid vehicle as described in any one of claim 6-8, which is characterized in that the pair
Motor is BSG motor.
10. a kind of computer readable storage medium, which is characterized in that have and be stored in instruction therein, when described instruction is held
When row, the hybrid vehicle executes the control method of finished as described in any one of claim 6-9.
