Abstract: To provide a novel colitis ameliorating agent. A colitis ameliorating agent comprising a trans-astaxanthin derivative of formula (I), geometric isomers thereof, a mixture of the geometric isomers, an optical isomer thereof, or a salt thereof; (wherein m1, m2, n1, and n2 are each the same or different and mean an integer of 1 to 6).

Abstract: A vehicle speed control apparatus is configured to determine, based on an automatic brake duration time and a vehicle speed reduction amount, whether to suppress a brake force due to an automatic brake control, the automatic brake duration time being from an automatic brake control starting timing to a current time point, the vehicle speed reduction amount corresponding to a value obtained by subtracting a vehicle speed at the current time point from the vehicle speed at the automatic brake control starting timing.

Abstract: A vehicle drive assist apparatus for assisting in driving a vehicle by varying drive torque of wheels that includes: a torque-up mechanism increasing the drive torque; a step detecting mechanism detecting a step that may exist on a road surface in a traveling direction of the vehicle; and a switching mechanism switching a status of control between a first status in which the torque-up mechanism is permitted to operate and a second status in which the torque-up mechanism is restricted to operate, wherein the switching mechanism forms the first status if the step is detected by the step detecting mechanism.

Abstract: A collision predicting apparatus detects subject targets present in the traveling course of the own vehicle by using the relative distance and the relative velocity, etc. The apparatus also calculates the predicted collision time of each subject target on the basis of the relative distance and the relative velocity. The apparatus also detects the relative lateral position of each subject target, and corrects the relative lateral position. The apparatus then executes a collision-predicted target selecting routine, in which the predicted collision time of each subject target that does not meet a predetermined condition is set at a predetermined maximum value. The apparatus selects a subject target that meets the predetermined condition as a collision subject target, and predicts whether the collision subject target will collide with the own vehicle.

Abstract: A vehicle drive assist apparatus with high convenience in which torque-up is performed only if there is an instruction from the driver. The vehicle drive assist apparatus assists in driving a vehicle by varying a drive torque of wheels, and includes a torque-up mechanism increasing the drive torque and a switch switching, in accordance with an input from a vehicle occupant, a status of control between a first status in which the torque-up mechanism is operational and a second status in which the torque-up mechanism is not operational.
