Abstract: A vehicle turning behavior control apparatus comprises a controlling section which limits a turning behavior of a vehicle caused by a steering operation, to a limit behavior corresponding to an actual steering speed, by a vehicle speed decrease. The controlling section is configured to determine a modified steering speed in accordance with the actual steering speed, and to determine the limit behavior in accordance with the modified steering speed. The controlling section is further configured to make the modified steering speed higher than the actual steering speed when the actual steering speed decreases during a turning steering for increasing a steering amount. For example, the actual steering speed is used directly as the modified steering speed while the actual steering speed during the turning steering is increasing. While the actual steering speed during the turning steering is decreasing, the modified steering speed higher than the actual steering speed is used.

Abstract: A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle, and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential and performs an assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential.

Abstract: A brake control apparatus includes a fluid pressure sensor to sense an actual master cylinder pressure, a pump to suck a brake fluid from the master cylinder through a hydraulic circuit connecting the master cylinder to a wheel cylinder and a controller to perform a brake assist control to supply a discharge pressure of the pump to the wheel cylinder in accordance with the sensed actual master cylinder pressure signal. The controller calculates a modified master cylinder pressure by modifying the actual master cylinder pressure in accordance with an operating condition of the pump, calculates a base pressure in accordance with a variation of the modified master cylinder pressure, and calculates a target wheel cylinder pressure in accordance with the base pressure, to control a braking force by controlling an actual wheel cylinder pressure of the wheel cylinder in accordance with the target wheel cylinder pressure.
