Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a method for discharging washing water onto the windshield of an automobile, which stores command data for intermittent water dispensing intervals and controls the intermittent dispensing of water onto the windshield using a microcomputer. This relates to a control device.

[Conventional technology]

Generally, the water flowing to the windshield of an automobile has a washing water dispensing device, a washing water storage tank, and a water dispensing instruction input device, and the washing water dispensing is controlled by controlling the water discharging to the windshield while the driver is instructing the water to flow. Izumi is held.

FIG. 7 is a block diagram of a device showing an example of conventional windshield cleaning. 2 is this windshield cleaning device that provides water to the windshield and serves as the source of power when cleaning the windshield. Reference numeral 3 denotes a cleaning operation start signal output device for outputting a cleaning start signal to the windshield cleaning device 2, and the windshield cleaning device 2 starts cleaning in response to a signal output from this device. Reference numeral 4 denotes a cleaning start instruction output device that instructs the cleaning operation start signal output device 3 to start cleaning the windshield. Upon output of a start instruction from this device, the cleaning operation start signal output device 3 instructs the windshield cleaning device 2 to start cleaning. Outputs start signal. 5 is based on the windshield cleaning instruction data input by the driver.
A cleaning operation interval device 6 controls continuous or intermittent output of a cleaning start instruction from the cleaning start instruction output device 4 to the cleaning operation start signal output device 3; This is a cleaning operation instruction/operation method input device for inputting cleaning instructions and command data for continuous operation or intermittent operation. 7 is a device for discharging washing water onto the windshield, and serves as a power source for dispensing water.

Reference numeral 8 indicates a washing water storage tank that stores washing water to be discharged to the windshield, 9 indicates a pipe that supplies washing water from this tank 8 to the washing water dispensing device 7, and 1o indicates a pipe that the driver uses to connect the washing water dispensing device 7 to the windshield. This is a water outflow instruction input device that instructs the outflow of washing water.

Next, the operation will be explained. When the windshield becomes dirty, the driver uses the cleaning operation instruction/operation method input device 6.
Input an instruction to start the operation of the windshield cleaning device 2 and command data for continuous operation or intermittent operation method to 0.
Next, the cleaning operation control device 5 controls the output of the cleaning start instruction according to the operation method command data input by the driver.

When the cleaning operation control device 5 issues a cleaning start instruction through this control, the cleaning start instruction output device 4 outputs a cleaning start instruction to the cleaning operation start signal output device 3. A cleaning start signal is output to the device 2, and the windshield cleaning device 2 cleans the windshield by outputting this signal. The necessity of washing water for cleaning the windshield is determined by the driver, and when it is determined that it is necessary, the driver inputs a water injection instruction to the water injection instruction input device 10.Then, the washing water injection device 7 stores the washing water. Washing water in a tank 8 enters through a pipe 1 and exits to the windshield. Water is continuously discharged onto the windshield while the driver is inputting a water discharge instruction to the water discharge instruction input device 10.

Note that if the instruction content of the operation method in the command data is continuous operation, the cleaning operation control device 5 outputs the cleaning start instruction continuously, and if it is intermittent operation, it outputs the cleaning start instruction after a certain period of time. The above output control is repeated until the driver instructs to stop the cleaning operation. During the control, the driver can change the command data of the operation method, and the cleaning operation control device 5 can change the command data that has been changed. A cleaning start instruction is output according to the instructions.

Next, the operation of the present invention will be explained with reference to the flowchart in FIG. 6 showing the control contents of the cleaning operation/water output control means 24 shown in FIG. 2.

First, in step 61, the command data inputted by the driver into the cleaning operation instruction/operation method input device 6 and the water output instruction/water output interval input device 11 of the windshield cleaning/washing device 1 and the cleaning water presence/absence detection means 23 output. Data on the presence or absence of wash water in the wash water storage tank 8 is taken in, and in step 62 it is determined whether there is a water out instruction. If there is no instruction to supply water, the process advances to step 73, and if there is an instruction to supply water, it is determined in step 63 whether or not there is cleaning water in the cleaning water storage tank 8.

If there is no washing water, the process proceeds to step 73, and if there is washing water, then in step 64, the intermittent interval value of water flowing to the windshield inputted by the driver is read out based on the number of windshield cleaning operations, and in step 65, this intermittent water is released. 0 to determine the interval value
If the intermittent interval value is rOJ, the process proceeds to step 73, and if the intermittent interval value is equal to or greater than rlJ, the process waits for input of a cleaning start instruction output from the cleaning start instruction output device 4 in step 66. When input, the number of inputs of the cleaning start instruction held in the RAM 34 is counted up in step 67, and the number of inputs is compared with the intermittent interval value read out in step 64 in step 6B. If the number of inputs is less than the intermittent interval value, the process proceeds to step 74, and if the number of inputs is greater than or equal to the intermittent interval value, a water output signal is output to the washing water dispensing device 7 in step 69, and the washing water is discharged to the windshield, and step 70 In step 70, a cleaning start instruction is output to the cleaning operation start signal output delay means 25, and after a delay corresponding to the water flow time, a cleaning start instruction is outputted to the cleaning operation start signal output device 3, and in step 71, R is outputted.
The number of inputs for cleaning start instructions held in AM34 is set to "0".
"Clear 0" Next, in step 72, it is determined whether the driver continues to input cleaning instructions for the windshield cleaning device 2 into the cleaning operation instruction/operation method input device 6 shown in FIG. If so, the process advances to step 61, where the cleaning operation and water output control are repeated. If no cleaning instruction has been input, the cleaning operation and water output control are ended. In step 73, the cleaning start instruction output device 4 waits for the input of the cleaning start instruction, and when the cleaning start instruction is input, in step 74, the cleaning start instruction is output to the cleaning operation start signal output device 3 shown in FIG. Proceed to step 72, and if there is a cleaning instruction, return to step 61 again.
If there is no cleaning instruction, the operation ends.

In the embodiment, a case has been described in which the cleaning operation and water output control are performed on the windshield, but the present invention can also be applied to a device that performs the cleaning operation and water output control on the rear window glass.

〔Effect of the invention〕

As explained above, according to the present invention, since the configuration is such that washing water can be automatically discharged onto the windshield at intervals specified by the driver, even if the driver performs the water discharge operation while driving, the operation will not be affected. This allows the driver to drive safely without being distracted.
