摘要： A steering device is provided for controlling steering torque applied to a steering wheel of a vehicle. A braking device is provided for controlling longitudinal force applied to each wheel, and a control device is provided for performing at least one of an anti-skid control and a traction control. It is observed whether the control device is performing the control on a split road surface. The steering torque is controlled on the basis of a difference of longitudinal force applied to the right and left wheels, and a turning state amount deviation between a turning state amount and a desired amount thereof. The desired amount of turning state is calculated, on the basis of the turning state of the vehicle obtained when one of the anti-skid control and the traction control is performed on the split road surface.

摘要： A projection type display apparatus is arranged to be able to implement both brightness-priority display and color-reproduction-priority display by itself. In the display apparatus, white light from a light source 1 is separated into beams of three colors by a color separation optical system comprised of a combination of dichroic mirrors DM1, DM2, total reflection mirrors M1, M2, M3, etc., and the beams of the three colors are made incident to liquid-crystal display units 8R, 8G, 8B. After that, the beams are combined by a dichroic prism 9 and images of the liquid-crystal display units 8R, 8G, 8B are projected by a projection lens 10. In this display apparatus, a dichroic filter DF for transmitting light in a region not less than a certain wavelength (for example, about 600 nm) but intercepting light in the other region is arranged so as to be able to be put into or out of an optical path immediately before the liquid-crystal display unit 8R. When the dichroic filter DF is not put in the optical path, the light in the wavelength region not less than about 570 nm is used as projection light. When the dichroic filter DF is put in the optical path, the light in the region not less than about 600 nm is used as projection light in the red band.
