<P>PROBLEM TO BE SOLVED: To attain desired acceleration/deceleration of a vehicle while suppressing variation in acceleration/deceleration. <P>SOLUTION: In a hybrid vehicle having at least one motor-generator serving as one power supply and traveling by transmitting power to tires through a speed change gear of fixed or variable speed change ratio, a first motor torque control means, including a vehicle speed sensor 8, a wheel speed sensor 13, a means 61 for receiving motor-generator torque, rotational speed of the output shaft and rotational speed of wheel and estimating torque reaction from a drive shaft to a driving force compound speed change gear TM and traveling resistance torque as disturbance, a disturbance offset amount operating means 63 for operating a torque reaction estimate of reverse sign as disturbance offset torque, a means 62 for operating a target acceleration of the vehicle from a target driving force and a traveling resistance torque estimate, and a means 64 for operating the sum of the disturbance offset torque and the target acceleration as a target motor torque, is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
