<P>PROBLEM TO BE SOLVED: To provide a motor torque controller of a vehicle in which desired deceleration of a vehicle can be attained by eliminating an influence of driving system inertia at the transient time of acceleration/deceleration of the vehicle without using a sensor for detecting the driving force. <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, there is provided a first motor torque control means which comprises; a vehicle speed sensor 8 for detecting the rotational speed of the output shaft of the speed change gear; a means 61 for receiving the rotational speed of the output shaft and a target motor torque and estimating torque reaction from the tire stem to the speed change gear as disturbance; a driving force control means 62 for operating a driving force control torque such that the difference is eliminated between the driving force estimate, i.e. the disturbance estimate, and a target driving power being set depending on a request from a driver or a system; and a means 64 for operating a target motor torque being output to the motor generator depending on the driving force control torque. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
