A travel controller includes: an information acquisition part configured to acquire braking state information of a braking device brake state, travel road information, and an ACC-ECU configured to perform travel, based on a set vehicle speed, and follow-up travel control under which the subject vehicle follows another vehicle traveling ahead thereof. After canceling activation of the travel control during the activation of the travel control, when the information acquisition part acquires travel road information showing that a travel road on which the subject vehicle is traveling is not a downhill road any longer, even if a braking performance index based on the braking state information acquired by the information acquisition part is not increased with respect to a second reference threshold, then the ACC-ECU allows the travel control activation to be resumed.

Travel controller

A travel controller including an information acquisition part configured to acquire brake state information of a braking device of a host vehicle and an ACC-ECU configured to perform travel control, wherein the travel control includes constant speed travel control and headway travel control. The constant speed travel control is configured to control the host vehicle to travel at constant speed in accordance with a preset target vehicle speed. The headway travel control is configured to control the host vehicle to travel by following another vehicle travelling ahead so that a predetermined inter-vehicle distance in maintained with the other vehicle and the host vehicle travels in accordance with the target vehicle speed. In the ACC-ECU, when a braking performance index of the host vehicle has a 'declined value', a target acceleration of Example 1 takes a reduced value compared to the target acceleration of Comparative Example for a common distance difference.

Travel controller adaptive to road inclination or braking performance

A traveling control apparatus includes: an information obtainer configured to obtain braking state information of a braking device in the host vehicle; and an ACC-ECU configured to execute traveling control including constant speed traveling control to cause the host vehicle to travel at a constant speed based on a preset vehicle speed, and follow-up traveling control to cause the host vehicle to travel so as to follow another vehicle traveling ahead of the host vehicle at a predetermined inter-vehicle distance. The ACC-ECU deactivates the ACC at a time when a braking performance index EV, derived from braking state information obtained by the information obtainer while the ACC being in operation, is deemed to be decreased by more than a predetermined first variation width IN_dif, as compared with a braking performance index EVat a time of the ACC having been activated.

Traveling control apparatus

A dual clutch automatic transmission includes a one-way clutch provided in a driving force transmission path that establishes a first certain gear ratio in a first set of gear ratios. A driving transmission direction of the one-way clutch is set such that a rotation inputted from a wheel side to an output member in a predetermined rotational direction is transmitted to the input shaft. The predetermined rotational direction corresponds to a backward movement of a vehicle. If an off-gear operation cannot be performed for a transmission gear with interlock, the driving force of the driving source is input to the input shaft to enable the off-gear operation.

Automatic transmission and control method of automatic transmission

A dual clutch automatic transmission includes a one-way clutch provided in a driving force transmission path that establishes a certain gear ratio in a first set of gear ratios. A driving transmission direction of the one-way clutch is set such that a rotation inputted from a wheel side to an output member in a predetermined rotational direction is transmitted to the input shaft. The predetermined rotational direction corresponds to a backward movement of a vehicle. On condition that the traveling state of the vehicle reaches a predetermined deceleration state, switching control of setting the gears for the first set to a neutral position can be executed.

A sliding bearing includes: an upper casing; a synthetic resin-made lower casing which is superposed on the upper casing so as to be rotatable about an axis in a circumferential direction relative to the upper casing; a synthetic resin-made sliding bearing piece disposed in an annular space between the upper casing and the lower casing; and a synthetic resin-made seal member for sealing respective other annular end portions, communicating with the outside, of a gap on an inner peripheral side and a gap on an outer peripheral side in a radial direction between the upper casing and the lower casing, the gap and the gap respectively communicating with the annular space at their one annular end portions.

A synthetic resin-made thrust sliding bearing includes a synthetic resin-made upper casing which is fixed to a vehicle body side via a mounting member; a synthetic resin-made lower casing which is superposed on the upper casing so as to be rotatable about an axis in a circumferential direction relative to the upper casing; and a synthetic resin-made sliding bearing piece disposed in a space between the upper casing and the lower casing.

The thrust slide bearing () has a synthetic resin bearing body () having a ring-shaped upper surface () that functions as a sliding surface, a ring-shaped metal plate () that is supported on the ring-shaped upper surface () to be freely rotatable relative to the bearing body (), and a ring-shaped cover () disposed so as to cover the ring-shaped upper surface () and the ring-shaped metal plate (). The ring-shaped metal plate () has an inner disc section () that is formed as a unit with an outer disc section () and is disposed in the through hole () of the ring-shaped cover (). The inner disc section () also functions as a reinforcing part (rib) of the outer disc section (). Thereby, the deformation of the thrust slide bearing ()is prevented even when a large force is applied via the piston rod.
