Abstract: A vehicle travel control apparatus includes an information acquiring section; a determining section that determines whether a special road terrain exists; and a speed control section that controls a speed of the subject vehicle. The speed control section is further configured to: when the special road terrain exists but a preceding vehicle does not exist, increase or decrease the speed of the subject vehicle with respect to a pre-set vehicle speed in the energy efficiency zone such that the energy efficiency is improved; and when the special road terrain and a preceding vehicle exists and the speed of the subject vehicle is planned to increase in the energy efficiency zone, control the speed of the subject vehicle in an inter-vehicle distance maintenance zone such that the subject vehicle has an inter-vehicle distance to the preceding vehicle longer than a pre-set inter-vehicle distance.

Abstract: A travel controller recognizes an action of a driver of a vehicle from image data of the driver. The travel controller obtains information indicating that determination of whether autonomous driving of the vehicle is permissible cannot be given. When the information indicating that determination of whether the autonomous driving of the vehicle is permissible cannot be given is obtained, the travel controller operates a human interface to request the driver for an instruction to drive the vehicle. The travel controller determines whether the driver is giving an instruction to drive the vehicle from an action of the driver recognized in response to the request for an instruction to drive the vehicle. When determined in the determination process that the driver is giving an instruction to drive the vehicle, the travel controller operates a drive system of the vehicle to permit autonomous driving of the vehicle.

Abstract: A control apparatus for a moving body generates a trajectory plan that is a plan indicating a lateral position of the moving body at each point when the moving body is caused to travel along a predetermined route. The control apparatus generates a speed plan that is a plan indicating a traveling speed of the moving body at each point when the moving body is caused to travel along the route. The control apparatus causes the moving body to travel based on both the trajectory plan and the speed plan. The control apparatus generates the speed plan as a plan for causing the moving body to travel based on the trajectory plan after the the trajectory plan is generated.

Abstract: A backward movement control device performs a backward movement control of an articulated vehicle including a tractor that includes steered wheels and a trailer towed by the tractor. The tractor is equipped with a steering control device that executes feedback control for causing a steered angle of the steered wheels of the tractor to follow a target steered angle. The backward movement control device includes a control unit configured to calculate the target steered angle such that a virtual steered angle follows a target virtual steered angle when a backward movement operation of the articulated vehicle is performed. The virtual steered angle is a steered angle of steered wheels that are virtually present in the trailer if the trailer is regarded as a rigid vehicle. The target virtual steered angle is a target value of the virtual steered angle that is set through a specific operation by an operator.

Abstract: A control device includes a model generation unit that generates a control model that formulates a task to be executed, and a task processing unit that causes the vehicle to execute the task by performing model prediction control using the control model. Assuming that a first state space is a state space of the control model used at an execution time of the first task, and a second state space is a state space of the control model used at an execution time of the second task, the task processing unit starts to cause the vehicle to execute the second task, after executing a transition process that is a process of making a value of a state variable that is commonly included in both the first state space and the second state space within a predetermined range that is allowed at the execution time of the second task.

Abstract: A vehicle control device includes a command unit that generates a command value for an actuator and causes a vehicle to travel by outputting the command value to a control unit, a state quantity acquiring unit that acquires at least two values of a vehicle state quantity among a vehicle state quantity ideal value, a vehicle state quantity detection value, and a vehicle state quantity operation value, an event storage unit that stores multiple events that can occur when the vehicle on-board device is not functioning normally, an event acquiring unit that compares at least two values of the vehicle state quantity and acquires an event corresponding to a result of the comparison, and an anomaly determining unit that determines whether there is an anomaly in the vehicle on-board device by using a Bayesian network that includes, as a node, an occurrence probability of the event.

Abstract: A driving assistance device calculates the field of view of a driver based on an output signal of a camera that captures an image of the driver. The driving assistance device calculates a monitoring required region that requires monitoring when driving the vehicle based on information of the periphery of the vehicle. The driving assistance device determines whether the field of view calculated in the field of view calculation process encompasses the monitoring required region. When determined that the calculated field of view does not encompass the monitoring required region, the driving assistance operates predetermined hardware device to cope with the situation.
