<P>PROBLEM TO BE SOLVED: To provide a torque response control apparatus of an electric motor so that acceleration feeling of a vehicle may become close to the requested acceleration corresponding to change of an operating condition. <P>SOLUTION: When a vehicle speed VSP is low, the motor torque response is made a low response by making a torque response determination coefficient K small, and the motor torque response is made a high response by making the torque response determination coefficient K larger as the vehicle speed VSP becomes higher. Thereby delicate operation requested by a low vehicle speed can be easily performed, torque rising becomes quick by a high vehicle speed, and acceleration feeling requested by the high vehicle speed can be satisfied. During small load with small gas pedal opening APO, the motor torque response is made a low response by making the torque response determination coefficient K small, and the motor torque response is made a high response by making the torque response determination coefficient K larger as the load becomes larger. Thereby delicate operation requested by a low load can be easily performed, torque rising becomes quick by large load, and acceleration feeling requested by large load can be satisfied. <P>COPYRIGHT: (C)2012,JPO&INPIT |
