摘要

A vehicle steering control system (10) that controls the operation of an electric vehicle steering device, which applies a steering assist force to a steering mechanism via a gear mechanism (16, 17), and includes a temperature estimating section (31) for estimating the temperature of or around the gear mechanism (T_gear); and a correcting section (32) for correcting the steering assist force according to the estimated gear temperature.
