    摘要： A collision avoidance system for a work machine includes at least one sensor configured to generate a signal indicative of a presence of at least one obstacle in a surrounding area of the work machine. The collision avoidance system also includes a controller communicably coupled with the sensor. The controller is configured to receive the signal indicative of the presence of the obstacle in the surrounding area of the work machine from the sensor. The controller is also configured to determine a position of the obstacle relative to the work machine based on the signal received from the sensor. The controller is further configured to generate a control signal to prevent a movement of the work machine, halt the movement of the work machine, or reduce a velocity of the work machine based on the determination of the position of the obstacle.

    摘要： A method of determining the yaw rate ({circumflex over (ω)}t) of a target vehicle in a horizontal plane by a host vehicle equipped with a radar system, said radar system including a radar sensor unit adapted to receive signals emitted from said host vehicle by said target, comprising: emitting a radar signal at a single time-point instance and determining from a plurality (m) of point radar detections measurements captured from said target vehicle by said radar sensor unit in said single radar measurement instance, the values for each point detection of range, azimuth and range rate; [ri, θi, {dot over (r)}i]; determining the values of the longitudinal and lateral components of the range rate equation of the target (ct, st) from the results ({dot over (r)}i, θi,) and the sensor unit or host vehicle longitudinal velocity and vs is the sensor unit or host vehicle lateral velocity; determining the orientation angle of the target (γt,scs); determining the target center (xt and yt) from the results (ri, θi); determining a line lPH perpendicular to the orientation of the target and passing through the center of the target (xt,c,scs, yt,c,scs); determining a line lCA passing through the center of rotation of said target and the position of radar sensor unit of said vehicle; determining the intersection point of the lines lCA and lPH being the position of the center of rotation [{circumflex over (x)}t,COR, ŷt,COR] of the target; h) estimating and yaw rate {circumflex over (ω)}t from the position of the center of rotation found in step f) and components of range rate equation of the target (ct or st) of step b).

    摘要： There is provided a driving assistance device. When there is a possibility that weather influences a detection performance of a vehicle detection unit configured to detect a preceding vehicle traveling in front of a subject vehicle and to measure an inter-vehicular distance to the preceding vehicle, a speed reduction control assistance unit enables a speed reduction control unit to perform a primary speed reduction control at a predetermined distance ahead of an entry or an exit of a tunnel-shaped road structure. Thereafter, when the vehicle detection unit detects the preceding vehicle and the inter-vehicular distance is equal to or smaller than a predetermined value, the speed reduction control assistance unit enables the speed reduction control unit to perform a secondary speed reduction control.

    摘要： A first travel controller of a control device for a vehicle sets a first target drive force based on preceding vehicle information to control a power source when a follow-up system is in an active state. A second travel controller sets a second target drive force based on a driver's operation to control the power source when the follow-up system is in an inactive state. A third travel controller sets a third target drive force that changes from the first target drive force toward to the second target drive force to control the power source when the follow-up system is switched from the active state to the inactive state. The third travel controller makes a difference between a change rate of the third target drive force set after the cancel operation and a change rate of the third target drive force set after the brake operation.
