A moving object operation management device for managing the operation of moving objects that move in a passage provided in an area and perform work at a specific place. When the work of a certain moving object hinders the movement of another moving object in a passage, the exclusive section and the exclusive section for one of the two moving objects are adjacent to each other, and when the movement of the shortest path to the next destination is hindered by the other exclusive section, the first operation instruction for moving one to the next exclusive section and after the exclusive section of the other section is released. And a second operation instruction to move the one moving object to the next destination by the shortest path, by comparing the arrival time to the one of the next destination in accordance with the instructions, configured to selectively emit.

Moving object operation management device

A moving object operation management device is configured to set an exclusive section when a work of a certain moving object inhibits movement of a passage of another moving object, and to selectively issue a first operation instruction for moving one of the two moving objects to the next destination on a path bypassing the exclusive section for the other when the exclusive section for one of the two moving objects and the exclusive section for the other object are adjacent to each other and the movement on the shortest path to the next destination is inhibited by the other exclusive section, and a second operation instruction for moving one of the two moving objects to the next destination on the shortest path after the exclusive section for the other object is released, by comparing the arrival time to the one next destination when the instruction is followed.

A vehicle control device includes: a steering device, a steering control device, a surroundings monitoring device, and a controller. The controller is configured to execute: a route calculating process of calculating a target route, a trajectory calculating process of calculating a target trajectory of an own vehicle in one or more roads of the target route; a steering-angle calculating process of calculating a target steering angle; a behavior detecting process of detecting information on a behavior of the own vehicle; a rut determining process of determining presence or absence of a rut on the target trajectory based on a detection result obtained by the surroundings monitoring device and/or a detection result obtained in the behavior detecting process, a drivable or non-drivable determining process of determining whether the own vehicle is drivable over the rut, and a correcting process of correcting the target trajectory and/or the target route.

Vehicle control device including control based on determined ruts in the road

An autonomous driving vehicle includes a first reference straight steering angle acquisition unit configured to acquire a first reference straight steering angle which is a steering angle of the autonomous driving vehicle in a straight travelling state, a second reference straight steering angle acquisition unit configured to acquire a second reference straight steering angle which is the steering angle when a magnitude of a difference between an estimated yaw rate estimated from the steering angle of the autonomous driving vehicle and the yaw rate of the autonomous driving vehicle detected from the yaw rate sensor is less than a yaw rate threshold value, and an autonomous driving permission unit configured to permits an autonomous driving of the autonomous driving vehicle when both the first reference straight steering angle and the second reference straight steering angle are acquired.

Autonomous driving vehicle, method for controlling autonomous driving vehicle, and program

An automatic steering system comprises a controller. The controller executes target steering angle calculation processing. The controller further calculates a learning value of lateral acceleration. The learning value is calculated based on an error of a detected value of the lateral acceleration by an acceleration sensor and an estimation value of the lateral acceleration calculated using driving speed and yaw rate. In the target steering angle calculation processing, it is judged whether the acceleration sensor is normal. If it is judged that the acceleration sensor is normal, a target steering angle is calculated by using the detected value. Otherwise, the lateral acceleration used to calculate the target steering angle is switched from the detected value to a backup value of the lateral acceleration. The backup value is calculated using the estimation value and the learning value calculated before a timing at which the acceleration sensor is judged to be abnormal.

Automatic steering system and automatic steering method

A braking control apparatus for a combination vehicle including a tractor vehicle and a trailer vehicle coupled to each other comprises a braking device that applies braking forces to wheels and a control unit that controls the braking device. The control unit performs behavior control to stabilize behavior of the tractor vehicle by applying a braking force or braking forces to a predetermined wheel or wheels of the tractor vehicle when turning behavior of the tractor vehicle is not stable, and, when the control unit applies a braking force or braking forces to a predetermined wheel or wheels, applies braking forces to the wheels of the trailer vehicle which are according to a force acting on the trailer vehicle by the tractor vehicle due to the application of the braking force or braking forces being applied to the predetermined wheel or wheels of the tractor vehicle.
