摘要： Driving support ECU sets a driver's state to “temporarily abnormal” and decelerates a vehicle when a driver of the vehicle has been first determined to be in an abnormal state where the driver loses an ability to drive the vehicle. Driving support ECU changes the driver's state to “regularly abnormal” in a case when the abnormal state of the driver remains unchanged when a vehicle speed decreases to a set vehicle speed, and at this point, reports to a help net center HNC. With this configuration, a report to the help net center HNC can be made at an appropriate timing.

摘要： An electrostatic steering wheel hold detection device includes: a first heater element located in a steering wheel, and has one end electrically connected to a power source; an inductor—that is electrically connected to an other end of the first heater element; a second heater element that is included in the steering wheel, and has one end electrically connected to the other end of the first heater element via the inductor; and a sensor circuit that is electrically connected to a connection point between the first heater element and the inductor, and detects, from a change in capacitance at the connection point, whether or not the steering wheel is held. An other end of the second heater element is electrically connected to a ground. The second heater element is located lower than the first heater element in the steering wheel when the steering wheel is in a neutral position.

摘要： A vehicle traveling control apparatus of the invention stops a vehicle by causing a braking force applying device to apply a braking force to the vehicle after determining that a driver is under an abnormal state. When a stop of a control for maintaining a vehicle at a stopped state is requested while a shift lever is set at a range other than parking and neutral ranges, the apparatus limits a driving force requested for a driving force supplying device to supply to drive wheels, to a value smaller than a driver's requesting driving force.

摘要： A vehicle traveling control apparatus includes an abnormality monitoring device which determines whether or not a driver of a vehicle is in an abnormal state where the driver loses an ability to drive the vehicle, and a decelerating device which decelerates the vehicle to automatically stop the vehicle after a conclusive abnormality determination time point which is a time point when the abnormality monitoring device finalizes the determination that the driver is in the abnormal state. The decelerating device is configured to prohibit the deceleration of the vehicle when the vehicle is in the deceleration prohibition situation after the conclusive abnormality determination time point.

摘要： Abnormality determination for a driver is appropriately made in accordance with a peripheral state when lane keeping assist control is being carried out. When a no-driving operation state has continued for a period equal to or more than a set period, a driving support ECU determines whether or not a change inhibition condition set in advance in relation to a peripheral state of an own vehicle is satisfied. When the change inhibition condition is not satisfied, the driving support ECU sets a control mode of LKA to a “weaker mode” to decrease a control amount of the LKA. As a result, the own vehicle swerves in a lane, and a driver who has not fallen into an abnormal state can be prompted to carry out a steering wheel operation. Thus, it is possible to discriminate a driver who has fallen into the abnormal state and a driver who has not fallen into the abnormal state from one another. When the change inhibition condition is satisfied, the driving support ECU sets the control mode of the LKA to a “normal mode”.

摘要： A driving assistance system includes a center configured to: obtain and integrate travel information of a plurality of vehicles by communicating with the vehicles; estimate a target stop position being a position at which the vehicle should stop based on the travel information; transmit the target stop position to the vehicle, and the center is configured to; obtain an index indicating a convergence property of driving behavior of a driver of each of the vehicles from the travel information; and eliminate stop position information based on the travel information of the vehicle driven by the driver with a low convergence property from an aggregate on the center based on the index.

摘要： A vehicle travel control apparatus includes an actuator and an electronic control unit. The electronic control unit is configured to determine whether a driver of a vehicle is in an abnormal state where the driver loses an ability of driving the vehicle. The electronic control unit is also configured to stop the vehicle at an abnormality determination time point onward, and control a vehicle speed by using the actuator such that the vehicle speed does not become lower than a lower limit vehicle speed in a period from the abnormality determination time point to a time point when the vehicle is stopped. The lower limit vehicle speed is set in accordance with a road shape influencing timing when a driver of another vehicle traveling behind the vehicle visually recognizes the vehicle.

摘要： A stop line position estimation device includes a traffic signal recognition unit configured to recognize a traffic signal at an intersection ahead of a vehicle and a stop line position estimation unit configured to estimate that a position of the stop line is a position from the traffic signal by a first distance toward the vehicle side. When the traffic signal recognition unit recognizes a plurality of traffic signals and the stop line position estimation unit recognizes an immediate front traffic signal and a rear traffic signal based on a positional relationship between the traffic signals, the stop line position estimation unit estimates that the position of the stop line is a position from the immediate front traffic signal by a second distance toward the vehicle side. The second distance is shorter than the first distance.

摘要： A vehicle traveling control apparatus stops a vehicle when the driver is under the abnormal state that the driver loses an ability of driving the vehicle, and then performs a stopped state maintaining control to maintain the vehicle at the stopped state. The control apparatus forbids a termination of the stopped state maintaining control if the acceleration pedal operation amount is equal to or greater than a threshold value greater than zero when the termination of the stopped state maintaining control is requested.

摘要： A driver is prevented from carrying out hands-free driving while lane keeping assist control is being carried out, thereby appropriately determining an abnormal state of the driver. When a steering wheel no-operation state continues for a first period or more, a driving support ECU sets a control mode of LKA to a “weaker mode”, thereby decreasing a control amount of the LKA. As a result, an own vehicle swerves within a travel lane, and the driver neglecting the steering wheel operation can be prompted to operate the steering wheel. Further, when the no-driving operation state continues for a second period or more, the driving support ECU establishes determination that the driver is in an abnormal state, returns the LKA to a “normal mode”, and decelerates and stops the own vehicle.
