Patent ID: 7460943

Claim:
A electronic control unit for controlling a sequential gearshift range of a motor vehicle equipped with an internal combustion engine, a power transmission assembly, and a motor, where the power transmission assembly transmits at least part of output power of the internal combustion engine, which is driven at an arbitrary drive point regardless of a gearshift position, to an axle and the motor is capable of outputting power to the axle, said electronic control unit comprising: a driving force demand setting module that sets a driving force demand to be output to the axle; an effective drive point setting module that, in the case of no change of the gearshift position, sets an effective drive point to a specific drive point determined under a preset restriction according to the driving force demand, and in the case of a change of the gearshift position, sets the effective drive point to an updated drive point with at least a change of a rotation speed of the internal combustion engine from the specific drive point determined under the preset restriction according to the driving force demand; and a control module that controls the internal combustion engine, the power transmission assembly, and the motor to drive the internal combustion engine at the set effective drive point and to ensure output of a driving force equivalent to the driving force demand to the axle.
