Abstract: An extraneous-matter removing apparatus according to an embodiment includes a connector, a detector, and a removal unit. The connector is connected with a branch wire branching from a camera wire. The camera wire transmits a start-up signal for starting up a camera provided outside of a vehicle. The detector detects the start-up signal flowing through the branch wire connected with the connector. The removal unit performs, when the detector detects the start-up signal, a removing operation of an extraneous matter attached to the camera.

Abstract: When a crankshaft reversely rotates immediately before a stoppage of an engine, the amount of fuel injection in a cylinder in an expansion stroke is controlled to acquire a target air-fuel ratio in accordance with the amount of air in the cylinder. When the electronic control unit determines that the exhaust valve is opened at the time of reverse rotation, the amount of fuel injection is determined by considering a change in the amount of air due to exchange of gas with an exhaust path.

Abstract: A driving circuit according to an embodiment includes a driving unit, a first temperature detecting unit, an overheat protecting unit, a second temperature detecting unit, and a failure diagnosing unit. The driving unit supplies a driving current to a load based on a control signal input from a controller. The overheat protecting unit blocks supply of the driving current to the load when the level of the signal output from the first temperature detecting unit exceeds a temperature threshold. The failure diagnosing unit blocks supply of the driving current to the load and outputs a signal of a level corresponding to a temperature out of a temperature range detectable by the second temperature detecting unit to the controller when it is determined that the first temperature detecting unit breaks down.

Abstract: An abnormality detection device includes a measuring unit 14c and a determining unit 14d. The measuring unit 14c measures, among a power supply, a capacitor, a load circuit, a switch connecting the power supply to the load circuit, and ground of a vehicle body, which are mounted on a vehicle, a first voltage of the capacitor charged by serially connecting the power supply, the capacitor, and the body ground in a state where the switch is controlled to be turned off. The determining unit 14d determines that the switch is not fixed in an ON state and an insulation resistance of the vehicle is normal when the first voltage measured by the measuring unit 14c is less than a first threshold.

Abstract: An image processing apparatus for processing an image according to one embodiment includes a generating unit, a display control unit, and a change receiving unit. The display control unit generates a synthetic image providing a view of a vehicle from a virtual viewpoint, based on a plurality of onboard camera images. The display control unit displays the generated synthetic image on a display unit. The change receiving unit receives a change in the relative positional relation between an image region that is based on one of the camera images and image regions that are based on the other camera images in the synthetic image. The generating unit generates a synthetic image, based on a changed positional relation every time a change in the positional relation is received.

Abstract: When a microcomputer does not charge an electric storage device, the microcomputer activates at an interval set based on a timer set value and determines whether an electric power voltage generated by a solar cell is equal to or higher than an electric power generation determination threshold. When the generated electric power voltage is lower than the electric power generation determination threshold, the microcomputer turns to a sleep state after increasing the timer set value by an addition set value while prohibiting charging the electric storage device. When the generated electric power voltage is equal to or higher than the electric power generation determination threshold and a generated electric power amount is equal to or larger than an electric power generation determination threshold, the microcomputer starts charging the electric storage device so the electric power device can be appropriately charged with an electric power generated by the solar cell.

Abstract: Even if a problem has occurred with respect to a multimedia micro-computer that generates a composite image including guiding lines, while a gearshift of a vehicle is in reverse, a reset process is not performed for the multimedia micro-computer. The reset process is performed after the gearshift is determined to have moved from reverse.

Abstract: A power-supply monitoring device includes a capacitor that is connected to an insulated electric power source to execute charging/discharging. A power-supply monitoring device including this capacitor forms a charging path for detecting deterioration in an insulation resistance of an electric power source, and detects a voltage of the capacitor when being charged through this charging path. A vehicle controller specifies an abnormal part based on whether or not the voltage of the capacitor detected by the power-supply monitoring device is within a predetermined range.

Abstract: An electric storage apparatus according to one aspect of an embodiment includes a battery unit, a determination unit, a virtual processing unit, and a connection controlling unit. The battery unit includes storage batteries to be connected in parallel. The determination unit determines, when the battery unit is started up, a startup type indicating a discharge start or a charge start. The virtual processing unit generates connection orders. Each of the connection orders is obtained by virtually and sequentially connecting in parallel storage batteries, of the storage batteries, having potential differences within a predetermined range so as to equalize electric potentials of the storage batteries. The connection controlling unit selects, among from the connection orders, a connection order in which the equalized electric potential is an electric potential according to the startup type determined by the determination unit, so as to connect in parallel the storage batteries.
