摘要:
In vehicular velocity controlling method and apparatus for an automotive vehicle, an inter-vehicle distance from the vehicle to a preceding vehicle which is running ahead of the vehicle is detected, a target vehicular velocity is calculated to make a detected value of the inter-vehicle distance substantially equal to a target inter-vehicle distance, a vehicular velocity of the vehicle is detected, the vehicular velocity of the vehicle is adjustably controlled to make a detected value of the vehicular velocity substantially equal to the target vehicular velocity, a target braking pressure for a vehicular brake system is calculated in accordance with a target deceleration variable calculated on the basis of the target vehicular velocity and the detected value of the vehicular velocity; and a limitation on a rate of increase in the target braking pressure is placed when the target braking pressure is in excess of a predetermined braking pressure threshold value.
摘要:
In automatic velocity controlling apparatus and method for an automotive vehicle, an inter-vehicle distance detector is provided for detecting an inter-vehicle distance from the vehicle to another vehicle which is running at the detected inter-vehicle distance with respect to the vehicle. A vehicular running controller is provided for effecting a vehicular running control such that the vehicle follows up the other vehicle maintaining the inter-vehicle distance to the other vehicle at a predetermined inter-vehicle distance. An inter-vehicle distance determinator is provided for determining whether the inter-vehicle distance detector transfers from a first state in which the inter-vehicle distance to the other vehicle is detected to a second state in which the inter-vehicle distance to the other vehicle is undetected. A deceleration controlled state determinator is provided for determining whether the vehicle is in a deceleration controlled state when the inter-vehicle distance determinator determines that the vehicle has transferred from the first state to the second state. A deceleration keep command generator is provided for generating and outputting a vehicular deceleration keep command to the vehicular running controller to maintain a vehicular deceleration at a value which is immediately before the inter-vehicle distance determinator determines that the inter-vehicle distance detector has transferred from the first state to the second state when the deceleration controlled state determinator determines that the vehicle is in the deceleration controlled state.

Lateral displacement reference positions LXL, LXR are set on left and right from a center in a width direction of a traffic lane L where a vehicle travels. Then, at least in a case where the vehicle is positioned on an inner side of the left and right lateral displacement reference position LXL, LXR, the vehicle is feedback-controlled so as to decrease a yaw angle deviation. Further, in a case where the vehicle is positioned at an outer side of the left and right lateral displacement reference position LXL, LXR with respect to the traffic lane center, the feedback control is performed so as to decrease the angle deviation and a lateral displacement deviation.

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.

A headway maintenance assist system is provided with a correction section in which a drive force/accelerator actuation relationship between an accelerator actuation amount and a target drive force is changed to a drive force/accelerator relationship that is different than an ordinary drive force/accelerator relationship so that the driver more readily notices the accelerator reaction force when the accelerator reaction force is applied to the accelerator to alert the driver under prescribed conditions.
摘要:
A head bowl set of a bicycle and the like comprises a head tube, a front fork tube put through the head tube for connecting a handlebar support tube with the top end, a locking device disposed at the top end of the front fork tube to press against the handlebar support tube, a lower bowl set and an upper bowl set which are respectively disposed at the top end and the bottom end of the head tube, and a tightening member disposed between the cover member of the upper bowl set and the bearing for providing a pivoting and sliding effect between the front fork tube and the head tube. The tightening member is annular in shape and has a tapered portion, a straight wall and a hooked portion. The head bowl set has advantages of structural stability and easy assembly.
