Abstract: Processing to set a control mode of driving control is performed. In this setting processing, it is determined whether or not a predetermined condition in which a tracking performance of a vehicle state with respect to a target vehicle state decreases is satisfied. Then, when it is determined that the predetermined condition is satisfied, the control mode is switched from a normal mode to a temporary mode. In the temporary mode, generation of a driving plan is stopped. Alternatively, updating or referring to the driving plan generated while it is determined that the predetermined condition is satisfied is prohibited. Alternatively, an instruction value for control calculated using a target control value and a current vehicle state in the driving plan generated while it is determined that the predetermined condition is satisfied is modified.

Abstract: A stopping control apparatus for a vehicle includes: a braking apparatus; a gear-type automatic transmission installed in a powertrain; and a control device configured to control the braking apparatus and the automatic transmission. The control device is configured to shift, after a vehicle transitions from a travel state to a stop state, a range of the automatic transmission to a P range under a state where the braking force applied to wheels is a braking force for maintaining the vehicle in the stop state, and then reduce the braking force applied to the wheels. The control device is configured to change a decrease rate of the braking force such that the decrease rate after a time point at which a predetermined period has elapsed from a start of a decrease in the braking force is less than the decrease rate before the time point.

Abstract: The autonomous driving control apparatus includes a driving control unit capable of executing a first autonomous driving mode and a second autonomous driving mode having a higher travel performance than the first autonomous driving mode, a parameter changing unit changing at least a part of a control parameter of autonomous driving to a control parameter for executing the second autonomous driving mode during execution of the first autonomous driving mode, and a performance determination unit determining whether travel performance of an autonomous driving vehicle satisfies travel performance required for the second autonomous driving mode after change of the control parameter. When it is determined that the travel performance required for the second autonomous driving mode is satisfied, the driving control unit switches to the second autonomous driving mode.

Abstract: A method for inspecting a road surface condition includes the steps of obtaining detailed information on a road surface condition set for each inspection point based on a traveling record of a vehicle, and information on an own position of the vehicle, generating an inspection execution plan of the vehicle in the inspection point when the inspection point is included in a predetermined range in an advancing direction of the vehicle with the own position as a reference, performing evaluation of a road surface condition in the inspection point based on a traveling condition of the vehicle that is obtained during the inspection execution plan, and updating the detailed information on a road surface condition set for the inspection point based on latest information on the road surface condition the evaluation of which is performed.
