1. A washer apparatus for a vehicle, comprising:
an onboard camera that is placed at a rear side of the vehicle; a tank that is adapted to store washer fluid; a camera wash nozzle that is adapted to receive the washer fluid from the tank and to spray the washer fluid over one side of the onboard camera where a lens of the onboard camera is located; at least one window wash nozzle that is adapted to receive the washer fluid from the tank and to spray the washer fluid over at least one of a front window glass and a rear window glass of the vehicle, the at least one window wash nozzle including a rear window wash nozzle that is placed at the rear side of the vehicle to spray the washer fluid over the rear window glass; an electric pump that is adapted to pump the washer fluid from the tank and thereby to supply the washer fluid toward the camera wash nozzle and the at least one window wash nozzle; a washer switch that outputs a command to drive the electric pump when the washer switch is manipulated by a user of the vehicle; a main conduit that is adapted to connect between the electric pump and the at least one window wash nozzle to supply the washer fluid to the at least one window wash nozzle, the main conduit forming a flow passage between the electric pump and the rear window wash nozzle; a branch conduit that is branched from the main conduit and is adapted to connect between an upstream side portion of the main conduit, which is located on an upstream side of the branch conduit, and the camera wash nozzle to supply the washer fluid to the camera wash nozzle; a switching device that is provided at a location between the upstream side portion of the main conduit and the branch conduit and is adapted to connect the upstream side portion of the main conduit to one of the at least one window wash nozzle and the camera wash nozzle, wherein the switching device is configured to, when the switching device receives an electric signal, which indicates placement of the vehicle in a reverse drive mode, connect the upstream side portion of the main conduit to the camera wash nozzle through the branch conduit upon disconnecting the upstream side portion of the main conduit from the at least one window wash nozzle, a rear wiper motor that drives a rear wiper, which is adapted to wipe the rear window glass; and a controller that is configured to:
control the switching device to maintain the connection of the upstream side portion of the main conduit to the camera wash nozzle through a predetermined time period when the controller receives both of the electric signal, which indicates the placement of the vehicle in the reverse drive mode, and the command outputted from the washer switch;drive the electric pump to spray the washer fluid through the camera wash nozzle through the predetermined time period; anddrive the rear wiper motor to wipe the rear window glass with the rear wiper in a subsequent period, which is immediately after the predetermined time period and in which the controller continuously receives the command from the washer switch even after elapsing of the predetermined time period. |
