Abstract: In an automatic parking mode, a target path is obtained, and a vehicle is automatically controlled to follow the target path. When a driver intervenes steering of the vehicle, an anticipated course to be taken by the vehicle to follow after the intervention to the steering is calculated as a revised path. When the vehicle follows the revised path, if the vehicle is expected to be brought into contact with an obstacle, firstly, an alarm is raised. When an avoidance operation is performed after the alarm, an anticipated course to be taken by the vehicle to follow after the avoidance operation is re-calculated as a revised path. If no avoidance operation is performed or if the vehicle is expected to be brought into contact with the obstacle even when the vehicle follows the revised path, forced brakes are applied to the vehicle, and the automatic parking control is halted.

Abstract: A steering control apparatus obtains a steered amount by which a steered wheel is steered based on a left-and-right braking force difference control amount, a vehicle state control amount, and a steering control amount. The apparatus changes the magnitude of the braking force difference control amount and the magnitude of the vehicle state control amount according to a vehicle speed or to time elapsed from when braking started to be applied to the left and right wheels. Accordingly, the vehicle driving on a ?-split road is prevented from being deflected toward a side of higher friction coefficient due to the left-and-right braking force difference when the braking is applied.

Abstract: A disc-like grinding wheel 5 is formed with a circumferential groove 5a, the opposite walls of which define grinding surfaces 5b. A rotated carrier 3 brings a load pin 55 into rotary movement relative to the grinding wheel 5 rotated about an axis 5z, so as to pass the load pin 55 through space between the grinding surfaces 5b, whereby opposite end faces 55a of the load pin 55 are ground simultaneously. Thus, time taken by a grinding process may be reduced as compared with a conventional method wherein one end face is ground at a time.
