Abstract: The vehicle control apparatus is mounted on a vehicle. The vehicle control apparatus includes a cleaning unit capable of performing a first cleaning operation to clean a detecting surface part of a LiDAR using cleaning fluid, and a cleaning control ECU configured to execute a first light-degree cleaning process to let the first cleaning unit perform a first cleaning operation for a first light-degree cleaning time. The cleaning control ECU executes the first light-degree cleaning process when a first light-degree cleaning condition becomes satisfied within a first allowable period.

Abstract: There is provided a cleaning notification device including: a detection unit which, in a case where cleaning of an imaging device that is installed on a vehicle and captures images of the environment external to the vehicle has been performed, detects the line of sight of a user riding in the vehicle; and a processing unit which, in a case where the user is looking at a first display device that displays captured images that have been captured by the imaging device, executes a process relating to an implementation notification indicating that cleaning of the imaging device has been implemented.

Abstract: An in-vehicle sensor cleaning system installed in a vehicle includes: a cleaning unit configured to automatically or manually perform cleaning of an in-vehicle sensor installed in the vehicle; a setting unit configured to set an automatic cleaning function to on and off, the automatic cleaning function causing the cleaning unit to automatically perform the cleaning of the in-vehicle sensor; and a notification unit configured to provide a notification about switching a setting of the automatic cleaning function, based on information on past cleaning of the in-vehicle sensor, when the automatic cleaning function is set to off by the setting unit.

Abstract: A display control device installed in a vehicle includes a receiving unit that receives information concerning dirt of a vehicle-mounted sensor installed in the vehicle, and a control unit that controls display of a wash execution button displayed on a display device installed in the vehicle for executing washing of the vehicle-mounted sensor, based on the information concerning the dirt received by the receiving unit.

Abstract: A sensor surface cleaning apparatus for a vehicle includes at least one sensor or camera, at least one cleaning unit for jetting a cleaning liquid toward a sensor surface of the sensor or camera, and a travel control ECU which operates in accordance with its operation mode switchable between a first mode in which automatic cleaning operation is permitted and a second mode in which the automatic cleaning operation is not permitted. In a period during which the operation mode is the first mode, the travel control ECU switches the operation mode to the second mode upon satisfaction of at least one of a first particular condition showing an environment in which the sensor surface easily becomes dirty and a second particular condition showing that dirt on the sensor surface cannot be removed by the cleaning liquid.

Abstract: A sustained release solid dosage preparation is provided comprising an active ingredient admixed with an excipient. At least part of the excipient consists of glucomannan microparticles having an average particle size less than 50 ?m. The glucomannan microparticles forms, when absorbing water, a hydrogel matrix for the active ingredient capable releasing the active ingredient almost entirely up about 6 hours.
