ABSTRACT:
In an automotive vehicle equipped with an electrically power-assisted steering system including an electric motor in drive connection to a steering shaft to produce an assist power in accordance with the driver's effort applied to the steering shaft, a signal is produced at each travel of the vehicle in a predetermined distance, and a physical value related to the assist power of the motor is detected in response to the signal. When the number of times of detection of the physical value reaches a predetermined time, a characteristic value of the detected physical values is calculated and compared with a standard value to determine a driving condition of the vehicle on a basis of the comparison.
