A travel control device performs blind area avoidance control when a host vehicle is in a blind area, a relative speed which is a value obtained by subtracting a speed of the host vehicle from a speed of an adjacent vehicle is larger than a first relative speed threshold value, the relative speed is smaller than a second relative speed threshold value, and an elapsed time from the point of time the host vehicle entered the blind area is an elapsed time threshold value or more and does not perform the blind area avoidance control when the host vehicle is not in the blind area, when the relative speed is the first relative speed threshold value or less, when the relative speed is the second relative speed threshold value or more, or when the elapsed time is shorter than the elapsed time threshold value.

Travel control device, travel control method, and non-transitory recording medium

A vehicle control device has a processor configured to detect an other vehicle in a detection modein a visual field boundary zone, detect the other vehicle in a detection modewith higher precision in a zone other than the visual field boundary zone, and, when a merging terrain exists and the other vehicle has been detected in the visual field boundary zone, generate a plan to control the speed of the own vehicle in a first deceleration modeuntil the other vehicle is detected in a zone other than the visual field boundary zone, or when the merging terrain exists and the other vehicle has been detected in a zone other than the visual field boundary zone, generate a plan to carry out space creation processing, whereby a space allowing the other vehicle to move from the adjacent lane is created.

Vehicle control device, storage medium storing computer program for vehicle control, and method for controlling vehicle

A travel control device includes acquisition part acquiring surrounding vehicle information and surrounding road environment information of a host vehicle and control part performing blind area avoidance control based on the surrounding vehicle information, the surrounding vehicle information includes a detection result of an adjacent vehicle traveling on a lane adjacent to a lane on which the host vehicle is traveling by a side sensor provided in the host vehicle, and the control part performs at least one of determining whether the host vehicle is overtaking the adjacent vehicle and suppressing the blind area avoidance control while the host vehicle is overtaking the adjacent vehicle, and determining whether the adjacent vehicle is overtaking the host vehicle and suppressing the blind area avoidance control while the adjacent vehicle is overtaking the host vehicle.

A travel controller determines whether a traveling lane in which a vehicle is traveling is a merged lane into which a merging lane merges using peripheral data that represents a surrounding situation of the vehicle, and while the traveling lane is the merged lane, repeatedly performs yielding determination to detect a merging vehicle traveling in the merging lane from the peripheral data, and to determine whether or not yielding control for securing a larger space for the merging vehicle to change the lane to the merged lane is necessary, the yielding determination at the first time being performed based on a relative positional relationship between the merging vehicle and the vehicle, the yielding determinations at the second and subsequent times being performed based at least on a result of a previous yielding determination, and controls travel of the vehicle according to the result of the yielding determination.

Travel controller and travel control method

A vehicle controller includes a processor configured to detect, ahead of a host vehicle, a merging section in which an adjacent lane adjacent to a host vehicle lane being traveled by the host vehicle merges into the host vehicle lane, detect one or more other vehicles traveling on the adjacent lane, determine whether to allow at least one of the detected vehicles to precede the host vehicle at a lane change of the one of the detected vehicles to the host vehicle lane in the merging section, and control acceleration or deceleration of the host vehicle so that a rear end of the host vehicle is ahead of a front end of a second vehicle following a first vehicle allowed to precede the host vehicle. The first and second vehicles are among the detected vehicles.

Vehicle controller, method, and computer program for vehicle control

A vehicle control device has a processor configured to set location 1 on an adjacent lane to be used for determining that an own vehicle is to travel ahead of another vehicle and set location 2 on the adjacent lane for determining to create a space allowing the other vehicle to move ahead of the own vehicle, determine whether a relationship 1 is satisfied in which a location of the own vehicle is ahead of the other vehicle while the other vehicle moves to location 1, determine whether a relationship 2 is satisfied in which a location of the own vehicle is behind the other vehicle while the other vehicle moves to location 2, and decide to cause the own vehicle to travel ahead of the other vehicle when relationship 1 is satisfied or decide to create a space ahead of the own vehicle when relationship 2 is satisfied.

A driving assistance device includes one or more processors configured to control operation of a host vehicle. The one or more processors are configured to perform first following control controlling acceleration and deceleration of the host vehicle so that the host vehicle follows a first preceding vehicle running in front of the host vehicle in the same lane as the host vehicle, and perform second following control prohibiting the first following control while a lane change is being performed and controlling acceleration and deceleration of the host vehicle so that the host vehicle follows a second preceding vehicle running in front of the host vehicle in a destination lane, if the lane change of the host vehicle is started during the first following control.

Driving assistance device

First target braking forces for front and rear wheels are calculated by distributing a target braking force of automatic braking to the front and rear wheels at a first front/rear wheel distribution ratio when braking operation is started by a driver during execution of the automatic braking control, second target braking forces for the front and rear wheels are calculated by distributing the braking force requested by the driver to the front and rear wheels at a second front/rear wheel distribution ratio preset to be different from the first front/rear wheel distribution ratio such that a pitch moment applied to a vehicle body due to braking forces of the front and rear wheels becomes zero, and braking forces of the front and rear wheels are controlled so as to be sums of the first and second target braking forces of the front and rear wheels, respectively.

Braking force control apparatus for a vehicle

A braking force control device is provided which has a control unit that controls an upstream braking actuator that generates a common upstream pressure for four wheels and a downstream braking actuator that individually controls the braking pressure supplied to each wheel using the upstream pressure. The control unit controls the upstream pressure so that the braking pressure of the front wheels is permitted to be higher than a lock pressure of the rear wheels but does not become higher than a lock pressure of the front wheels, and suppresses an increase of the braking pressure of the rear wheels so that the braking pressure does not become higher than the lock pressure of the rear wheels, in a situation where the upstream pressure can be supplied to each braking force generating device but the braking pressure of any one of the wheels cannot be decreased.

Braking force control apparatus for vehicle

The inventive vehicle braking control device performs a brake assist control of increasing a braking force for avoiding a collision of a vehicle at a more appropriate time. The device comprises a portion which acquires an estimated time until a vehicle reaches to an obstacle; a portion which judges based on a braking operation amount and a braking operation speed value if the driver performed an urgent braking operation; and a portion which determines the start of a braking force assist control when an urgent braking operation is judged in a case that the estimated time is less than a first predetermined time, wherein, if the estimated time is less than a second predetermined time shorter than the first predetermined time, the urgent braking operation is judged when the braking operation amount exceeds a threshold value irrespective of the braking operation speed value.
