Abstract: A navigation system and a wireless communication device are installed on an automobile. The navigation system determines the state vector of the automobile. The navigated state vector is periodically transmitted by the wireless communication device for use by other vehicles. The wireless communication device also receives state vectors transmitted from neighboring vehicles. The received state vectors are compared with the automobile's current state vector by a processor. The processor drives a display that displays the relative position of the neighboring vehicles. The processor also determines the likelihood of collision with another vehicle. The processor issues display or audio cues to alert the driver. The processor may also send brake or steering commands when a driving correction should be made.

Abstract: This invention allows personnel located on two different structures, such as two ships, to continually monitor the separation distance between the two structures, with all of the necessary equipment being located on only one of the structures. This is accomplished using a laser range finder, or other range sensor, to continually measure separation distance and send it electronically to various displays. The displays are positioned and sized such that all involved personnel can view the continually updating separation distances. The invention incorporates displays large enough to be viewed ship-to-ship in direct sunlight, in addition to smaller displays. The displays are dimmable or backlit for night viewing and include a safety feature that turns them off when communication is lost with any range sensor. A strobe on the display helps personnel find where the display has been positioned, such as on a ships gunwale or hand railing.

The warning device warns the vehicle to be warned when the harsh braking-applied vehicle is in front of the vehicle to be warned.

Abstract: When a deceleration intention detector detects that an occupant has apprehension about a condition ahead of his own vehicle and attempts to decelerate the own vehicle, a detection area setter enlarges a detection area in which a control object is detected, upon a command from a control object determinator. Therefore, a new control object such as a cutting-in vehicle can be more reliably detected in accordance with an increase in an amount of attention which the occupant pays to the condition ahead of the own vehicle. As a result, a vehicle controller changes a vehicle control content of the own vehicle, thereby performing an appropriate vehicle control with respect to the newly detected control object to eliminate a sense of discomfort of the occupant.

Abstract: Whether or not a radar device detects an object is determined by a detection state determinator. Whether or not a time during which the object is not detected and which is measured by a clocking device becomes a determination threshold value or more, is determined by a non-detection determinator. Based on the determination results, an informing device informs an occupant that the object is not detected for a predetermined time or more. Therefore, a state in which the radar device does not detect an object due to absence of the object on a road in a desert or the like is prevented from being erroneously determined as a state caused by contamination of the radar device. Also, the occupant can easily determine whether the operation of the informing device is actually caused by absence of an object or contamination of the radar device, based on the environment around the road on which the own vehicle is traveling.

Abstract: A braking control device performs a steering and/or avoidance possibility determination based on the state of the vehicle to execute automatic vehicle braking when an obstacle in front of the vehicle cannot be avoided by steering and/or braking. The device determines that the obstacle can be avoided by steering when the correlation value between steering avoidance time and relative velocity is smaller than the distance from the vehicle to the obstacle. The steering avoidance time is set to a shorter value when the suspension characteristic is stiffer and the sideways force generated by the front wheels is larger. The steering avoidance time is set successively shorter for low, high, and medium speed travel regions, respectively, to reflect the behavior response characteristic of the vehicle with respect to steering input. The vehicle deceleration that would occur if the driver released the accelerator pedal is considered in the braking avoidance possibility determination.

This avoidance path minimizes the negative effects of the resultant route diversion on the flight plan of the aircraft. A method prepares an avoidance path with two parts. The first part is an evasive part with an initial heading such that the threatening aircraft takes a path, in relation to the threatened aircraft, that is tangential, on one side or the other, to the edges of the angle at which the threatening aircraft perceives a circle of protection plotted around the threatened aircraft. The radius of this circle of protection is equal to a minimum permissible separation distance. The second part of the evasive path is that of homing in on the initial route. This method of preparing an avoidance path can be implemented by a flight management computer.
