Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To always jet an optimum amount of washer liquid without respect to a change in traveling condition by controlling a washer liquid jetting amount according to a traveling speed of a vehicle. SOLUTION: Jet control for washer liquid is repeated at a predetermined interval (for example, 16 ms, 1024 ms decided on the basis of a processing interval of an ECU 2 controlling a vehicle), and it is determined whether an operation switch 4 is turned on or off in the previous processing time. An action time T corresponding to a vehicle speed V is read out from a relation diagram between a vehicle speed and a motor action. It is determined whether a counter value C is equal to the action time T decided according to the vehicle speed V or less, and if it is below the action time T, an ON signal is outputted to a motor 3 for continuing the jetting action. When the counter value C is the operation time T or more, it means that a time T decided by the vehicle speed V is passed or the operation switch 4 is turned off by a driver, so that an OFF signal is outputted to the motor 3 for stopping the jetting action.
