<P>PROBLEM TO BE SOLVED: To provide a motor traction controller of a vehicle in which high precision slip control can be performed using road surface friction coefficient information by estimating a road surface friction coefficient simultaneously with the start of a drive slip. <P>SOLUTION: The motor traction controller comprises at least one motor attached to a power source for driving wheels, and a motor traction control means for recovering the grip of the wheel by motor torque down control by detecting the drive slip of the wheel wherein the motor traction control means has a means for detecting a value corresponding to slip start torque at the time of determining the slip start (step S12-step S14), and a means for estimating a road surface friction coefficient depending on the value corresponding to slip start torque from the means for detecting a value corresponding to slip start torque (step S15). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
