Abstract: In an ejector, formed in a body is a swirling space which lets a high-pressure refrigerant flowing from a refrigerant inlet port swirl and introduces the swirling high-pressure refrigerant into a depressurizing space in which the swirled high-pressure refrigerant is depressurized and expanded. A passage formation member that defines a nozzle passage and a diffuser passage is shaped to have a cross-sectional area increasing with distance from the depressurizing space. Further, a temperature sensing unit of a drive device that displaces the passage formation member is housed in the body, and the temperature sensing unit and a diaphragm have annular shapes to surround at least the axial line of the passage formation member.

Abstract: A traveling assistance apparatus controls a safety apparatus for avoiding collision between an own vehicle and an object, based on detection information from an object detection apparatus. The assistance apparatus calculates a predicted time to collision of a target object and the own vehicle, and operates the safety apparatus in response to the predicted time to collision being equal to or less than a predetermined operation timing. In response to a steering operation by a driver for collision avoidance of the own vehicle being performed, the assistance apparatus performs operation-stop in which operation of the safety apparatus is stopped or operation-delay in which the operation timing is delayed. The assistance apparatus suppresses the operation-stop or the operation-delay in response to a target object serving as a collision avoidance target being recognized in a path of the own vehicle after the steering operation by the driver, based on the detection information.

Abstract: A driving assistance device sets, in front of an own vehicle, an actuation region that is a region sandwiched by boundary lines, positioned at left and right, respectively. In a case where a target existing around the own vehicle has entered the actuation region, the device performs driving assistance for avoiding collision with the target or mitigating collision damage. The device, when setting the actuation region, in a case where the own vehicle is in a turning state, changes a lateral position of a boundary line in an outside in a turning direction of the own vehicle, of the left and right boundary lines of the actuation region, to a position closer to the own vehicle according to turning information. For a boundary line in an inside in a turning direction of the own vehicle, the device does not change a lateral position according to the turning information.

Abstract: A driving assistance apparatus determines, based on an instantaneous indicator which is an instantaneous value of a parameter regarding steering of the own vehicle, whether a driver has started a collision avoidance operation for avoiding a collision between a target and the own vehicle. When it is determined that the collision avoidance operation has been started, a support start timing for starting driving assistance for avoiding the collision or reducing collision damage is set to be a timing later than when the collision avoidance operation has not been started. The support start timing during a collision avoidance time period which is a time period until a predetermined set time has elapsed after it is determined that the collision avoidance operation has been started is set based on a time-dependent indicator for steering indicated by the instantaneous indicator at timings during the collision avoidance time period.

Abstract: In a driving assistance device for performing a driving assistance process to avoid or mitigate a collision between an own vehicle, which is a vehicle carrying the driving assistance device, and an oncoming vehicle detected within a predefined region ahead of the own vehicle, an entry determiner is configured to determine whether one of the own vehicle and the oncoming vehicle is likely to enter a lane in which the other one is present. An actuation controller is configured to, in response to the entry determiner determining that each one of the own vehicle and the oncoming vehicle is unlikely to enter the lane of the other, restrict actuation of the driving assistance process, and in response to the entry determiner determining that any one of the own vehicle and the oncoming vehicle is likely to enter the lane of the other, not restrict actuation of the driving assistance process.

Abstract: In a collision avoidance apparatus for a vehicle, a collision avoidance controller is configured to calculate a movement trajectory of a moving object moving on a road crossing a road that the vehicle is traveling on from a succession of locations of the moving object, calculate a movement trajectory of the vehicle using a speed of the vehicle, determine whether the movement trajectory of the moving object is a trajectory of a moving object likely colliding with the vehicle, and in response to determining that the movement trajectory of the moving object is a trajectory of a moving object likely colliding with the vehicle and that the moving object fails to be recognized by a camera due to a view of the moving object being obstructed, calculate a risk index for determining a collision avoidance measure and employ the collision avoidance measure in dependence upon the risk index.

Abstract: A sealing structure has a permanent magnet and a magnetic-flux guiding member for guiding magnetic flux of the permanent magnet to a brake shaft of a brake rotating member. The magnetic-flux guiding member surrounds an outer periphery of the brake shaft so as to form a sealing gap around the brake shaft. The sealing gap is communicated to a fluid chamber, in which magnetic viscous fluid is filled. A fluid sealing member is provided at the brake shaft at a housing outer side of the magnetic-flux guiding member to form an intermediate fluid chamber, in which an intermediate fluid made of non-magnetic liquid is filled.

Abstract: A fluid brake device includes a case defining a fluid chamber filled with magnetorheological fluid, a brake rotor having a magnetic part received in the fluid chamber, a coil that generates magnetic flux by being supplied with electricity, and a controller that controls electricity supplied to the coil. Magnetic particles are suspended in the magnetorheological fluid, and the magnetic flux passes through the magnetic part. The controller continues supplying the electricity to the coil while the brake rotor has a half rotation from a stop state where the brake rotor is stopped at a startup time at which the brake rotor starts rotating.

Abstract: In a vehicle control apparatus, an object recognizing block recognizes an object which is present around a vehicle. In cases where there is a possibility that the vehicle will collide with an object recognized by the object recognizing block, the apparatus performs automatic braking control which brakes the vehicle. If the driver depresses the accelerator pedal in a predetermined depressing state, a braking controlling block cancels the automatic braking control. When an operation determining block determines that there is a driver's predetermined shift-lever position change, with which the driver's predetermined shift-lever position change is carried out during a driver's accelerator pedal depressing operation, the braking controlling block responds to a driver's accelerator depressing operation by not cancelling the automatic braking control or by making cancellation of the automatic braking control more difficult.
