A automatic driving control apparatus for a vehicle can selectively switch a driving mode between a manual driving mode in which a driver manually performs driving operation of the own vehicle and an automatic driving mode in which driving operation is performed automatically along a set target traveling route. The automatic driving control apparatus includes a driving skill evaluation unit and a driving mode switching unit. The driving skill evaluation unit is configured to monitor the driving operation by the driver during traveling in the manual driving mode and evaluate a driving skill of the driver. The driving mode switching unit is configured to control the driving mode so as to be switchable to the automatic driving mode on condition that at least an evaluation value of the driver by the driving skill evaluation unit exceeds a threshold set in advance.

A vehicle travel locus transmission system to be mounted on a vehicle includes a GNSS receiver, a vehicle-side transceiver, a locator processor, a wheel speed sensor, a gyro sensor, and an acceleration rate sensor. The locator processor generates, on predetermined cycles, a latest first linear coordinate as a linear function parameter that couples latest first positional coordinates and second positional coordinates on a previous cycle. The first and second positional coordinates are to be acquired on the basis of a positioning signal received by the GNSS receiver. On the condition that an angle formed by the first linear coordinate with an extension of a second linear coordinate generated on the previous cycle exceeds a predetermined threshold, the locator processor sends data regarding the first linear coordinate together with vehicle identification data, from the vehicle-side transceiver to an external device.

A traffic control system includes a vehicle control apparatus and a traffic control apparatus. The vehicle control apparatus includes a travel environment data transmission unit and a travel control unit. The traffic control apparatus includes a data supplementability determination unit and a data supplementation unit. The data supplementability determination unit determines whether or not data regarding a communication-disrupted vehicle out of a plurality of vehicles is supplementable on the basis of travel environment data received from a nearby vehicle traveling near the communication-disrupted vehicle. The data supplementation unit generates traffic environment data supplemented with the data regarding the communication-disrupted vehicle, on the basis of the travel environment data received from the nearby vehicle, and transmits the traffic environment data generated, to the nearby vehicle.

An automatic driving assist apparatus includes a map information acquirer; an own vehicle position estimator; a route information input unit; a traveling environment information acquirer, a traveling route setting unit, an other-vehicle traveling route acquirer, and an automatic driving controller. The automatic driving controller further includes a target travel path generator, an other-vehicle detection determiner, and a relative vehicle speed determiner, an other-vehicle traveling route determiner, and an automatic traveling controller. The automatic traveling controller causes the own vehicle to travel following another vehicle along a target travel path generated by the target travel path generator in a case where the other-vehicle traveling route determiner determines that a traveling route of the other vehicle is set in a direction of a branch path.

An automatic drive assist apparatus includes a storage, an own-vehicle position estimator, a route-information input device, a traveling route setter, and an automatic drive controller including a rerouting request determiner, a course comparator, and a course-change achievability determiner. The automatic drive controller causes an own vehicle automatically traveling along a traveling route determined by the traveling route setter. When the rerouting request determiner determines that a new traveling route is reconstructed in response to a rerouting request, the course comparator reads a candidate route of the new traveling route, compares the candidate route with the traveling route determined before the reconstruction, and determines whether a route change is set. When the route change is determined not to be achievable by the course-change achievability determiner, the automatic drive controller causes the own vehicle to keep automatically driving along the traveling route determined before the reconstruction.

An automatic driving control apparatus for a vehicle can selectively switch between a manual driving mode in which a driver manually performs driving operation of the vehicle and an automatic driving mode in which driving operation is performed automatically along a target traveling route. The apparatus includes a driver identifier that identifies the driver, a driving experience value evaluation unit that evaluates a driving experience value based on a traveling history in the manual driving mode of the identified driver, a shift permission time setting unit that sets a shift permission time from the manual driving mode to the automatic driving mode based on the driving experience value, and a driving mode switching unit that controls the driving mode so as to be switchable to the automatic driving mode on condition that at least a driving time by the driver in the manual driving mode exceeds the shift permission time.

A driving control system includes an automatic driving control device and a driver monitoring device. The automatic driving control device includes a driver state determining unit, an override detector, a retreat mode controller, and a retreat mode canceler. During traveling under an automatic driving mode, when the driver state determining unit determines from a driver state detected by the driver monitoring device that the driver is not in a state capable of driving normally, the retreat mode controller sets a retreat mode in which an override operation is disabled and an own vehicle is caused to travel for retreat. When the driver state determining unit determines, during traveling for retreat, that the driver has returned to the state capable of driving normally, the retreat mode canceler cancels the retreat mode, and enables detection of the override operation of the driver by the override detector.

A vehicle driving control system has an automatic driving mode that enables traveling without a driver's operation. The vehicle driving control system includes a driver monitor that monitors a driver in a vehicle compartment, and detects a driver state, a driver state determining unit that determines, based on the driver state, whether the driver is in a state capable of driving normally, a retreat mode controller that controls a retreat mode that causes an own vehicle to travel for retreat to a place where the own vehicle can safely stop when it is determined, during traveling under the automatic driving mode, that the driver is not in the state capable of driving normally, and a retreat mode canceler that cancels the retreat mode when it is determined, during the travel for retreat, that the driver has returned to the state capable of driving normally.

An automatic driving control apparatus includes a controller. Upon execution of an automatic driving control of a vehicle, the controller determines, on the basis of a result of positioning and map information, presence or absence of a tollgate within a predetermined distance from the vehicle. The controller makes a transition to a tollgate passing mode, on a condition that the presence of the tollgate is determined within the predetermined distance and an increase in width of the road is further recognized on the basis of a result of recognition of an outside environment. In the tollgate passing mode, the controller sets a first target path on the basis of position information, of the tollgate, that is recognized on the basis of the result of the recognition of the outside environment. The first target path is a target path along which the vehicle is to pass through the tollgate.
