    摘要： A temperature sensor is disposed in an optical pickup to detect a temperature of an objective lens. An optical element (for example, a collimator lens) is driven according to a temperature change of the objective lens, which corrects deterioration of an optical characteristic of a laser beam passing through the objective lens. Good recording/reproduction is smoothly performed even if the optical characteristic of the objective lens is changed with the temperature change.

    摘要： In a vehicle equipped with a power steering device for assisting the steering of the steered wheels by the steering wheel, when the steering angle of the steered wheels reaches the maximum steering angle, a steering control device restricts a target steering angle for operating the power steering device so that the steering angle or a reaction force acting against the power steering device does not exceed a value determined therefor, so to maintain the steering condition of the steered wheels stably without applying an excessive load on the power steering device. The target steering angle may be calculated as a value based upon rotational angle of the steering wheel and turning behavior control of the vehicle.

    摘要： A motor-driven steering controller for controlling a steering wheel of a vehicle. The controller includes a steering torque controlling unit, a braking force estimating unit, a right and left braking force difference estimating unit and an assist steering torque providing unit. The steering torque controlling unit controls a steering torque on the steering wheel depending on a steering operation. The braking force estimating unit estimates braking forces to be imposed on wheels of the vehicle. The right and left braking force difference estimating unit estimates difference between the braking forces to be imposed on the right and left wheels each estimated by the braking forces estimating unit. The assist steering torque providing unit provides an assist steering torque for the steering torque controlling unit on the basis of the difference in braking force between right and left wheels estimated by the right and left braking force difference estimating unit.

    摘要： A steering control apparatus is provided for a vehicle having a steering wheel for steering steered wheels of the vehicle, a power source for generating power, and drive shafts for transferring the power to the steered wheels, to be served as driving wheels of the vehicle. The apparatus comprises an accelerating operation detection device for detecting accelerating operation amount by a vehicle driver, and a steering torque control device for controlling steering torque created by the steering wheel, and applying torque steer reducing torque to the steering wheel. The steering torque control device is adapted to reduce torque steer, which is transiently created on the steering wheel due to characteristics of the drive shafts, when the accelerating operation amount detected by the accelerating operation detection device becomes equal to or greater than a predetermined value.
