    • A system having a motor operatively connected to a steering system for reducing the steering effect is provided with a steering torque sensor for detecting steering torque in the steering system during a steering operation, an alternator output level sensor for detecting the output level of an engine driven alternator, and an ignition key switch sensor. In response to the output signal of the steering torque sensor, an assist signal is provided. In response to the output level of the alternator output level sensor and the position of the ignition key switch, an engine stall condition is detected. When engine stall occurs, the output torque of the motor is controlled in response to the assist signal for a predetermined period.

    • The present invention is characterized by repeatedly AD converting in a time series an output of each light sensitive element, and at the same time an added value or a mean value of each one of said AD converted values is obtained so that such added value or a mean value is used as an output of each light sensitive element. According to the present invention, an influence of flickering of an artificial light source can be eliminated and at the same time a light measuring computation with a high level of accuracy can be made with a higher speed than that in a conventional method, and particularly in a light measuring apparatus housing a number of light sensitive elements a light measuring computation with a high level of accuracy can be made in a by far faster speed than that in a conventional method.
