A driving control method is performed to execute a lane-change control for controlling a host vehicle to autonomously change lanes from a first lane to an adjacent second lane using a processor of a driving control device that controls vehicle speed and steering of the host vehicle traveling in the first lane in an autonomous driving mode. The processor determines that the lane-change control can be executed upon determining that the other vehicle has been detected in a detection zone of the second lane, based on a detection result of a sensor. The processor determines that the lane-change control cannot be executed upon determining that the other has not been detected within the detection zone of the second lane. The processor outputs information regarding whether the lane-change control can be executed.

Vehicle lane change control method and vehicle lane change control device

A driving control device controls driving of a subject vehicle at a predetermined driving assistance level using a processor under a condition of traveling behind a preceding vehicle. The processor determines whether another vehicle is detected in a second lane when the subject vehicle traveling in a first lane at the predetermined driving assistance level changes a lane to the second lane different from the first lane, keeps the traveling of the subject vehicle in the first lane until the other vehicle is detected when the other vehicle is not detected, and executes lane-change control at the predetermined driving assistance level after the other vehicle is detected.

Driving control method and driving control device

A processor of a driving control device that controls driving of a subject vehicle at a predetermined driving assistance level determines whether a transition request that requires transition of a driving assistance level from a first driving assistance level to a second driving assistance level higher than the first driving assistance level is input, and relaxes the transition condition for the transition of the driving assistance level from the first driving assistance level to the second driving assistance level when the transition request is input.

A driving control device includes a processor that controls driving of a subject vehicle using any one of a first driving mode and a second driving mode having a lower driving assistance level than that of the first driving mode. The processor is configured to: after the driving mode switches from the first driving mode to the second driving mode, determine whether or not a travel environment of the subject vehicle satisfies an automatic return-possible condition; and when the travel environment of the subject vehicle satisfies the automatic return-possible condition after the driving mode switches from the first driving mode to the second driving mode, output, to a user interface, first information indicating that the driving mode of the subject vehicle can be switched automatically from the second driving mode to the first driving mode.

Driving mode switching control method and driving mode switching control device

A processor of a driving control device compares a vehicle speed of a subject vehicle traveling in a first lane with a vehicle speed of an adjacent other vehicle traveling in a second lane to determine whether a relative speed of the adjacent other vehicle to the subject vehicle is equal to or less than a predetermined speed difference threshold, and relaxes a travel condition for permitting the subject vehicle to travel at a predetermined driving assistance level when the relative speed is equal to or less than the speed difference threshold.

A processor operates to: refer to a switching condition in which a vehicle speed and input form information of an input command are preliminarily associated with each other, to determine whether or not the input form of the input command satisfies the switching condition associated with the vehicle speed; when a determination is made that the input form of the input command satisfies the switching condition corresponding to the vehicle speed, switch a control mode of the vehicle from autonomous driving control to manual driving control based on the input command; and execute driving of the vehicle by the manual driving control.

Driving control method of vehicle and driving control device

A travel control method for a vehicle for executing autonomous travel control includes, prior to executing the autonomous travel control, presenting a driver with travel control information as to whether or not to accept execution of the autonomous travel control and detecting, in response to a presentation of the travel control information, an acceptance input made by the driver indicating that the driver accepts the execution of the autonomous travel control. The travel control method also includes: setting an input form of a present acceptance input by the driver to an input form different from an input form of a previous acceptance input.

Vehicle travel control method and travel control device

A parking control method causes a control device of a vehicle to execute a first control instruction for moving the vehicle along a first route to a target parking space, on the basis of an operation command acquired from an operator located outside the vehicle. This method includes, when execution of the first control instruction is suspended or canceled, calculating a second route for the vehicle to leave with a predetermined distance or more from an object detected around the vehicle and causing the control device to execute a second control instruction for moving the vehicle along the second route.

Parking control method and parking control device

A parking control method executes a control instruction for moving a vehicle along a parking route. The parking route is calculated based on an operation command acquired from an operator located outside the vehicle. The parking control method includes detecting a relative altitude between a first height position of the operator and a second height position of the vehicle and when determining that the relative altitude is not less than a first predetermined value, changing a first speed to a second speed lower than the first speed. The first speed is preliminarily set in the control instruction. The parking control method further includes moving the vehicle in accordance with the control instruction changed.

A travel control method for executing autonomous lane change control of a vehicle includes, before performing two or more successive lane changes, presenting the driver with first lane change information as to whether or not to accept execution of autonomous control of the successive lane changes; when detecting a first acceptance input made by the driver indicating that the driver accepts the execution of the autonomous control, executing first autonomous lane change control; then presenting the driver with second lane change information as to whether or not to accept execution of the autonomous lane change control after the first lane change; and when detecting a second acceptance input made by the driver, executing the autonomous lane change control after the first lane change. An action load of the second acceptance input is set smaller than an action load of the first acceptance input.

When executing the autonomous lane change control of lane change of the subject vehicle from the subject vehicle lane in which the subject vehicle travels to adjacent lane, the autonomous lane change control is executed so as to accelerate the lateral speed of the subject vehicle in the subject vehicle lane and thereafter decelerate the lateral speed in the subject vehicle lane. As a result, it takes longer for the driver of the following vehicle to confirm the lateral movement of the preceding subject vehicle during the lane change of the subject vehicle from the start of the lane change than a lane change in which the lateral speed is decelerated in the adjacent lane. Therefore, it becomes easier to recognize the lane change.

Vehicle travel control method and vehicle travel control apparatus

A parking control method includes: performing parking control of moving a vehicle to a target parking position on the basis of an operation command acquired from an operator located outside the vehicle; when the parking control to the target parking position is suspended and the vehicle leaves the target parking position, calculating a moving direction of the vehicle on the basis of a parking direction when the vehicle is parked at a next target parking position; and moving the vehicle in the moving direction.

Parking control method and parking control apparatus

When a subject vehicle performs first autonomous lane change control from a subject vehicle lane to an adjacent lane and then consecutively perform autonomous lane change control to a next adjacent lane in the same direction of lane change, lateral speed to perform second and subsequent autonomous lane change control is set slower than lateral speed to perform the first autonomous lane change control. Thus, the second and subsequent autonomous lane change control to the adjacent lane in the same direction of lane change is performed more slowly than the previously performed autonomous lane change control. Time used for confirming surrounding situations is lengthened, and the surrounding situations can be properly confirmed prior to the lane change.

Vehicle traveling control method and traveling control device

A parking control method calculates a first control instruction and causing a control device of a vehicle to execute the first control instruction on the basis of an operation command acquired from an operator. The first control instruction is for moving the vehicle along a first route to a target parking space. The parking control method includes: when detecting an object after start of execution of the first control instruction, presenting the operator with selection information for selecting a first mode in which the execution of the first control instruction is continued or a second mode in which the control device of the vehicle is caused to execute an alternative control instruction for moving the vehicle along an alternative route different from the first route; and causing the control device to execute the first control instruction or the alternative control instruction in accordance with selection input information from the operator.

An exit assist method is executed using an exit assist controller configured to control a subject vehicle to move from an exit start position to a target exit position along an exit route. The exit assist method includes determining whether or not an adjacent parked vehicle is present in an adjacent parking space to the exit start position, and when no adjacent parked vehicle is present, generating the exit route that includes the adjacent parking space.
