<P>PROBLEM TO BE SOLVED: To provide a controller for a vehicle drive system, which does not degrade the acceleration of a vehicle by more than required while suppressing the slip of a wheel in advance. <P>SOLUTION: A controller 80 for a vehicle drive system comprises a torque adjusting means 84 comprising an adding means 81, a gain means 82, and a motor second revolution speed adjusting means 83, an adding means 85, and a motor first control means 18. A threshold value of skidding speed is acquired from the characteristics such as a rolling friction (adhesion) between a wheel 4 and a rail which is not shown in Fig. and a differential speed (skidding speed) between a peripheral speed of the wheel 4 and a vehicle speed. A torque adjusting amount less than the threshold value is derived, and a motor 2 is vector-controlled with a torque set value (τ*) based on the derived value through a power convertor 1. <P>COPYRIGHT: (C)2004,JPO |
