A lane deviation prevention control device for a vehicle includes a target steering torque calculator, a friction torque estimator, and a friction compensation rate variable controller. The target steering torque calculator calculates target steering torque to be applied to a steering system of an own vehicle in a lane deviation prevention control. The friction torque estimator estimates friction torque of the steering system. The friction compensation rate variable controller performs, on the basis of steering torque produced by a driver's steering operation and on the basis of a traveling state of the own vehicle, a variable control of an addition rate at which the friction torque is added to the target steering torque to compensate friction of the steering system.

Lane deviation prevention control device for vehicle

A lane deviation prevention control apparatus of a vehicle calculates a lane width direction vehicle lateral position and a yaw angle of the vehicle with respect to a lane, calculates, on the basis of the lane width direction vehicle lateral position, the yaw angle, and vehicle speed, a lane deviation predicted time in which the vehicle deviates from the lane, calculates, on the basis of the yaw angle and the lane deviation predicted time, a target yaw moment applied to the vehicle for preventing deviation from the lane, observes a change rate of the target yaw moment, and, when the change rate of the target yaw moment is equal to or larger than a threshold set in advance, limits the change rate of the target yaw moment to be equal to or smaller than a change rate limit value variably set according to at least traveling road information.

An object is to overcome the drawbacks of conventional blue phthalocyanine pigments upon the formation of images, and to develop a blue pigment that can satisfactorily exhibit a greenish blue color high in chroma and excellent in colorfulness, brightness, dispersibility, hue, tinting power and the like and that is applicable to various image recording methods. The object can be achieved by a greenish blue pigment, which exhibits a greenish blue hue of high chroma and contains a pigment represented by the following formula (I): wherein the number, m, of substituent phthalimidomethyl group(s) is in a range of 1.0&#x2266;m&#x2266;5.0, and the number, n, of a substituent sulfonic group R1 is in a range of 0.05&#x2266;n&#x2266;1.0.
