PURPOSE: A monitoring apparatus is provided to maintain a motor torque within the range of the optimum value to transfer the maximum torque to be realized with available friction to the drive wheels, by comprising an adhesion monitoring means, a means for generating a signal to operate the monitoring apparatus and a means for applying an operation signal to the reference signal. CONSTITUTION: A friction monitoring apparatus(20) comprising a power control stage(18) includes a friction monitoring stage(22) for supplying the reference signal to a power control means(18) in order to transfer the maximum torque to the drive wheels. The friction monitoring stage(22) includes a first part suitable for calculation of amplitude of an operation signal C-Corr and a second part for determining the sign of the operation signal C-Corr. The second part of the adhesion monitoring stage(22) receives a signal Cm corresponding to a forecasted value of an electro-magnetic torque of a motor(12) as an input, and detects the direction of electro-magnetic torque that varies between the consecutive two times of activation. As a result, the maximum torque can be transferred to the drive wheels. |
