    摘要： An object of the present invention is to provide a driving assistance system capable of displaying a picked-up image near a vehicle as a less-distorted image on a monitor. A driving assistance system according to the present invention comprises an imaging means (2) for picking up a surrounding image of a vehicle (1) on a road surface, an image translating means (3) for executing an image translation by using a three-dimensional projection model (300), which is convex toward a road surface side and whose height from the road surface is not changed within a predetermined range from a top end portion of the vehicle (1) in a traveling direction, to translate the image picked up by the imaging means (2) into an image viewed from a virtual camera (2a), and a displaying means (4) for displaying an image translated by the image translating means (3). The three-dimensional projection model (300) is configured by a cylindrical surface model (301) that is convex toward the road surface side, and a spherical surface model (302) connected to an end portion of the cylindrical surface model (301). Accordingly, the straight line on the road surface, which is in parallel with the center axis of the cylindrical surface model (301), is displayed as the straight line, and thus a clear and less-distorted screen can be provided to the driver.

    摘要： An obstacle existing ahead of a vehicle is recognized to detect information on the obstacle. Information on travelling conditions of the vehicle is detected. The steering performance of the vehicle is changed for controlling behaviors of the vehicle. It is determined whether the vehicle can avoid collision with the obstacle only by a driver's braking operation based on at least the information on the obstacle and the vehicle. The vehicle enters into an evasive driving mode in accordance with a driver's steering operation when it is determined that the vehicle cannot avoid collision with the obstacle only by the driver's braking operation. The steering performance of the vehicle is changed for controlling behaviors of the vehicle. A preliminary information is given to the driver to indicate that the vehicle will enter into the evasive driving mode. The driver is then informed that the vehicle has entered into the evasive driving mode.

    摘要： Method and apparatus for obtaining distance data from an object to a lens by obtaining an image of the object by an image input unit for forming an image of the object through the lens on an image receiving plane. Two observed images Is and Is' with different blurs from the image input unit are obtained by making a position of the lens and/or a position of the image receiving plane with regard to the object different by a minute distance .DELTA.z. A filtering process is then performed by applying a filter to the two input observed images Is and Is', thereby providing two output images Fs and Fs'. The distance a up to the object is calculated by using the two output images Fs and Fs' obtained by the filtering process based on the relation between the two output images Fs and Fs' and radius s of the blur and the distance a from the lens to the object.

    摘要： In a method for controlling an active chassis of a vehicle, an obstacle is identified on a travel route located in front of a wheel of a front axle. A spring-shock absorber force of the spring-shock absorber system of the corresponding wheel is adjusted depending on the geometry of the obstacle such that the vehicle body experiences the lowest possible vertical acceleration when driving over the obstacle. Data from the front axle driving over the obstacle is then evaluated and adjustments are made for balancing the rear axle as it drives over the obstacle. When the rear axle drives over the obstacle, adjustments are made to at least one wheel of the rear axle, taking into account the adjustments due to the front axle driving over the obstacle, such that the vehicle body does not experience any vertical acceleration when the rear axle drives over the obstacle.

    摘要： A vehicular control system includes a forward-viewing camera, a forward-sensing sensor and a cabin-sensing imaging sensor. With the system controlling driving of the vehicle, the system determines a triggering event that triggers handing over driving of the vehicle to a driver of the vehicle before the vehicle encounters an event point associated with the triggering event. The vehicular control system (i) determines a total action time available before the vehicle encounters the event point, (ii) estimates a driver takeover time for the driver to take over control of the vehicle and (iii) estimates a handling time for the driver to control the vehicle to avoid encountering the event point. The vehicular control system estimates the driver takeover time based at least in part on processing by the vehicular control system of the in-cabin image data captured by the cabin-sensing imaging sensor.

    摘要： A control system that is operable to control a vehicle in an autonomous or semi-autonomous mode includes a processor that processes data captured by a plurality of exterior sensing sensors. When the control system is operating in the autonomous or semi-autonomous mode and responsive to a determination of an upcoming event that requires the system to hand over control of the vehicle to a driver before the vehicle encounters the event, the control determines (i) a total action time until the vehicle encounters the event, (ii) an estimated time for the driver to take over control and (iii) an estimated handling time for the vehicle to be controlled before the vehicle encounters the event. Responsive to the determinations, the control system (i) allows the driver to take over control of the vehicle or (ii) controls the vehicle to slow down and stop the vehicle before the vehicle encounters the event.
