Abstract: PURPOSE:To detect the intensity of each of lights with individual wavelengths even in a light flux containing light with different wavelengths by a method wherein a first semiconductor photodetector and a second semiconductor photodetector are provided and a wavelength absorption filter which absorbs light of a specific wavelength selectively is installed between the both. CONSTITUTION:When lights with wavelengths lambda1, lambda2 are directed to a reflectionless coating face 6 of a semiconductor photodetector I, most of them are directed to a p<+>-Si layer 8; a half of the light absorbed by a thin-layer p<+>-Si layer 9 and an n<+>-Si layer 10 is transmitted. Carriers which have been pumped optically at the layer 9 become a drift current and is taken out to the outside as an output A according to a light quantity of a half of the incident lights on the element I. In addition, the light with the wavelength lambda1 in the transmitted light is absorbed by a wavelength absorption filter 11; only the light with the wavelength lambda2 is incident on a semiconductor photodetector II. A thick-layer i-Si layer 3 absorbs the incident light totally; carriers which have been pumped here becomes the drift current; an output B according to a light quantity of the light with the wavelength lambda2 is taken out to the outside. Accordingly, when light quantities of the lights with the wavelengths lambda1, lambda2 are designated as p1, p2, p1/2 is obtained from the output A=(p1+p2)/2 and the output B=p2/2; both can be detected.

Abstract: PURPOSE:To keep rear wheels from being supplied with useless steering angles at the time of steering without driving while preventing the degradation of a steering control characteristic during normal travel by cutting integral arithmetic control quantity at the time of the load detection value of a rear wheel steering actuator exceeding the threshold, and resetting the integral arithmetic control quantity gradually at the time of the load detection value being lower than the threshold. CONSTITUTION:In the control method of a rear wheel steering system 8, the load of an electric motor 10 serving as a rear wheel steering actuator is detected and compared with the threshold shifted according to the operating state. At the time of the load detection value exceeding the threshold, integral arithmetic control quantity is cut, and at the time of the load detection value being lower than the threshold, the integral arithmetic control quantity is reset gradually. During normal travel without the demand of high follow-up performance in comparison, the integral arithmetic control quantity is daringly cut so as to be able to manage even with the small output capacity of the electric motor 10. Also the rise of the control quantity at the time of applying the integral arithmetic control quantity upon the lowering of load becomes gentle so as to obtain a smooth follow-up characteristic.
