Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle body control technology, specifically to a method for testing windshield wiper function. Background Technology
[0002] Car wipers are divided into front wipers and rear wipers. The main functions of the front wipers include low speed, high speed, intermittent, automatic, washing, and maintenance functions. The main functions of the rear wipers include low speed, washing, and automatic wiping in reverse.
[0003] In related technologies, testing of windshield wiper functions is mostly based on manual testing. For example, testing the low-speed wiping function of the front wiper requires first identifying the corresponding input / output pins for the low-speed wiper according to the controller's hardware interface definition table, switching the controller's power to the ON position, and then inputting a low-level signal to the controller's front wiper low-speed switch pin. A multimeter is then used to test the voltage of the controller's front wiper low-speed output pin; a 12V output indicates that the wipers are wiping at low speed. However, controllers have many connectors, each with dozens or even hundreds of pins. Manual testing requires a significant amount of time to locate these input / output pins, resulting in low efficiency and accuracy for manual wiper testing. Summary of the Invention

It is obvious that the drawings described below are merely some embodiments of this application, and those skilled in the art can obtain other drawings based on these drawings without any inventive effort.

[0045] Figure 3 This is a schematic diagram illustrating wiper controller interface configuration information, as shown in an exemplary embodiment of this application. Detailed Implementation
[0046] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0047] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0048] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.
[0049] First, it should be noted that, given the problems of low testing efficiency and low accuracy in manual wiper testing in related technologies, this application proposes a wiper function testing method, which uses a load box test bench to perform load control on the wiper controller and displays the results of the function control.
[0050] Figure 1 This is a schematic diagram illustrating the implementation environment of a wiper function testing method according to an exemplary embodiment of this application.
[0051] Reference Figure 1As shown, before performing the wiper function test method in this embodiment, a corresponding implementation environment needs to be set up. The load cell test bench and the controller are connected via a wiring harness. When connecting the wiring harness, the wiper-related pins need to be located according to the controller hardware interface definition table (i.e., the wiper controller interface configuration information). The wiper input pin of the controller is connected to the IDL (Interface Description Language) interface of the load cell test bench via the wiring harness. The wiper output pin is connected to the ODH interface of the load cell test bench. In this embodiment, the ODH interface is the input interface of the load cell test bench, mainly used to receive the test output signal from the wiper controller. For example, if the low-speed switch pin number of the front wiper is J2-12, then pin number 12 needs to be found on the connector numbered J2 on the controller, and this pin is connected to the IDL interface of the load cell test bench via the wiring harness.
[0052] For the wipers to function properly, the power must be on. During testing, the power setting is controlled by locking / unlocking the remote key. Therefore, the RF receiver must be connected to the corresponding LIN interface on the load cell platform to receive RF signals. Automatic wipers require a rain sensor signal, so the rain sensor pin on the controller must be connected to the LIN channel of the load cell platform. The test computer sends rain sensor control signals to the load cell platform via CANOE.
[0053] After completing the above implementation environment setup, the wiper function test method in this application embodiment can be carried out.
[0054] The above section introduced the exemplary implementation environment of the technical solution of this application. Next, we will continue to introduce the wiper function test method of this application.
[0055] To address the problems of low efficiency and low accuracy in existing manual wiper testing, embodiments of this application propose a wiper function testing method, which will be described in detail below.
[0056] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a windshield wiper function testing method according to an exemplary embodiment of this application. This method can be applied to... Figure 1 The implementation environment is shown. It should be understood that this method can also be applied to other exemplary implementation environments and specifically executed by devices in other implementation environments. This embodiment does not limit the implementation environment to which the method is applicable.
[0057] like Figure 2 As shown, in an exemplary embodiment, the wiper function testing method includes at least steps S210 to S230, which are described in detail below:
[0058] In step S210, the load input signal transmitted by the pre-configured load module is obtained.
[0059] For example, in this embodiment, the load module is a load box platform. By setting up the implementation environment, the pins of the wiper controller are connected to the pins of the load box platform. When the switch on the load box platform is adjusted to the output position, a load input signal is transmitted to the wiper controller. The load box platform has three output positions to the wiper controller: the middle position is floating, flipping it up results in a high level, and flipping it down results in a low level. The wiper switch is active low; therefore, to turn on the wiper switch, simply flip the corresponding wiper switch on the load box platform down. To turn off the wiper switch, the switch on the load box platform must be flipped to the middle position. The load box platform has two output positions to receive the wiper controller's output: flipping it up results in a high level, and flipping it down results in a floating position. The wiper outputs 12V when working; therefore, during wiper testing, flipping the interface on the load box platform that receives the wiper controller's output upwards will illuminate the corresponding indicator light, indicating that the wiper is working. When testing the wiper function using a load cell test bench, the test can be completed simply by toggling the switch on the load cell test bench panel and observing the changes in the indicator lights.
[0060] In step S220, the load input signal is transmitted to the target wiper function module according to the pre-configured signal transmission channel, so that the target wiper function module performs a function test according to the load input signal and outputs a test output signal during the function test.
[0061] For example, the target functional modules in the wiper controller in this application embodiment include a low-speed front wiper module, a high-speed front wiper module, an intermittent front wiper module, a front wiper maintenance module, a front wiper washer module, an automatic wiper module, and an automatic wiper attachment module. It should be noted that the wiper function test performed on the target functional modules in the wiper controller in this application embodiment is merely an illustrative example and does not imply that the target functional modules in the wiper controller are limited to the above-mentioned types. It is understood that in actual testing, the wiper controller may also include other target functional modules.
[0062] In step S230, the test output signal is transmitted to the load module according to the signal transmission channel, and the load module performs a preset action corresponding to the test output signal to complete the test of the target wiper function.
[0063] For example, after the test output signal is transmitted to the load module, the functional test results can be displayed through the indicator lights on the load module. For instance, if the test output signal indicates that the target wiper module is working normally, the load module controls the indicator lights to illuminate; if the test output signal indicates that the target wiper module is not working, the load module controls the indicator lights to remain off.
[0064] As can be seen from the above steps S210 to S230, the wiper function test method can be applied to the wiper function controller. The wiper function controller includes multiple target wiper function modules. The load input signal is transmitted to the target wiper function module through a pre-configured load module to complete the function test. Compared with manual operation, it can simplify the test operation, improve the test efficiency, and ensure the test quality.
[0065] In one embodiment of this application, before acquiring the load input signal transmitted by the pre-configured load module, the method further includes:
[0066] Call the pre-configured wiper controller interface configuration information;
[0067] According to the wiper controller interface configuration information, the input pins of each target wiper function module are connected to the output pins of the load module, and the output pins of each target function module are connected to the input pins of the load module to complete the construction of the signal transmission channel.
[0068] For example, see Figure 3 , Figure 3 This is a schematic diagram illustrating wiper controller interface configuration information, as shown in an exemplary embodiment of this application. Figure 2 The input and output pins of the target functional module in the wiper controller were defined, and the effective values were used to determine how each pin should be connected to the load cell chassis. The load cell chassis and the controller are connected via a wiring harness, and the wiring harness connection needs to be based on… Figure 3 Locate the wiper-related pins in the wiper controller interface configuration information shown. Connect the wiper input pin of the controller to the IDL interface of the load cell platform via a wiring harness, and connect the wiper output pin to the ODH interface of the load cell platform. For example, if the low-speed switch pin number of the front wiper is J2-12, then find pin number 12 on the connector numbered J2 on the controller and connect this pin to the IDL interface of the load cell platform via a wiring harness.
[0069] In one embodiment of this application, before acquiring the load input signal transmitted by the pre-configured load module, the method further includes:
[0070] Obtain the remote key unlock signal transmitted by the load module;
[0071] Based on the remote key unlock signal, switch the power setting to the on setting.
[0072] For example, the windshield wipers operate normally only when the power is on. During testing, the power setting is controlled by locking / unlocking the remote key. Therefore, the RF receiver also needs to be connected to the corresponding LIN (Local Interconnect Network, a serial communication protocol) interface on the load cell bench to receive RF signals. Automatic wipers require rain sensor signals, so the rain sensor pin on the controller also needs to be connected to the LIN channel on the load cell bench. The test computer sends rain sensor control signals to the load cell bench via CANOE (a bus development environment).
[0073] In one embodiment of this application, transmitting the load input signal to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test includes:
[0074] The load input signal is transmitted to the front wiper low-speed wiping module to control the front wiper to wipe at a preset first speed and output a test output signal when the front wiper is wiping.
[0075] If the load input signal stops transmitting within a first time, then the front wiper is controlled to stop wiping within a first time.
[0076] For example, when the front wiper operates at a preset first speed, it is considered low-speed wiping. The steps for low-speed wiping are as follows: unlock the remote key and switch the power to the ON position; turn on the front wiper low-speed switch (i.e., slide the front wiper low-speed switch on the load box platform down), the front wiper will perform low-speed wiping, and the indicator light for the front wiper low-speed wiping on the load box platform will illuminate; turn off the front wiper low-speed switch (i.e., slide the front wiper low-speed switch on the load box platform to the middle position), and if no wiper stop signal is received, the front wiper will stop wiping after 6 seconds, at which point the indicator light for the front wiper low-speed wiping on the load box platform will turn off; if a stop signal is received within 6 seconds, the wiper will stop immediately.
[0077] In one embodiment of this application, the load input signal is transmitted to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test, including:
[0078] The load input signal is transmitted to the front wiper high-speed wiping module to control the front wiper to wipe according to the preset second speed, and outputs the test output signal when the front wiper is wiping the root.
[0079] If the load input signal stops transmitting within a first time, then the front wiper is controlled to stop wiping within a first time.
[0080] For example, when the front wiper operates at a preset second speed, it is considered high-speed wiping. The steps for high-speed wiping are as follows: unlock the remote key and switch the power to the ON position; turn on the high-speed front wiper switch (i.e., slide the high-speed front wiper switch on the load box platform down), and the front wiper will perform high-speed wiping. At this time, the indicator light for high-speed front wiper on the load box platform will illuminate; turn off the high-speed front wiper switch (i.e., slide the high-speed front wiper switch on the load box platform to the middle position). If no wiper stop signal is received, the high-speed front wiper will stop wiping after 6 seconds. At this time, the indicator light for high-speed front wiper on the load box platform will turn off. If a stop signal is received within 6 seconds, the wiper will stop immediately.
[0081] In one embodiment of this application, transmitting the load input signal to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test includes:
[0082] The load input signal is transmitted to the front wiper intermittent wiping module, and the pre-configured front wiper intermittent time is called;
[0083] Based on the aforementioned windshield wiper interval time, control the windshield wipers to perform intermittent wiping, and output a test output signal when the windshield wipers are wiping intermittently.
[0084] If the load input signal stops transmitting during the second time period, then the front wiper is controlled to stop wiping during the second time period.
[0085] For example, a typical intermittent wiper mode has six settings: Level 1 - 1-second interval; Level 2 - 3.5-second interval; Level 3 - 6-second interval; Level 4 - 9.5-second interval; Level 5 - 15-second interval; and Level 6 - 22-second interval. The default intermittent setting is Level 3. The intermittent setting is adjusted via a central locking soft switch. This soft switch cannot be operated during standalone testing. The controller communicates with the central locking system via Ethernet, and the operation of the soft switch can be simulated by calling the controller's service interface. The intermittent wiper test procedure is as follows: Unlock the remote key and switch the power to the ON position; call the wiper interval time setting service and set the interval level to level 5; turn on the front wiper intermittent switch (pull the front wiper intermittent switch on the load box stand down), and the front wipers will wipe at low speed; within 6 seconds, pull the front wiper stop signal down to stop the low-speed wiping, and resume low-speed wiping after 15 seconds; turn off the intermittent switch, and if no wiper stop signal is received, the front wipers will wipe at low speed for 6 seconds and then stop wiping; if a stop signal is received within 6 seconds, the wipers will stop immediately.
[0086] In one embodiment of this application, transmitting the load input signal to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test includes:
[0087] The load input signal is transmitted to the front wiper maintenance module;
[0088] If the front wiper is not in the preset maintenance position, the front wiper is controlled to reach the preset return position according to the load input signal, and then moves from the return position to the maintenance position within a third time period, and a test output signal is output within the third time period.
[0089] If the front wiper is in the return position, the front wiper is controlled to move from the return position to the maintenance position within a third time period according to the load input signal, and a test output signal is output within the third time period.
[0090] For example, the front wiper maintenance mode includes the following steps: unlocking the remote key and switching the power to the ON position; quickly operating the wiper switch from OFF→HIGH→OFF within 2 seconds (during the HIGH position, high-speed wiping occurs), activating the maintenance mode; during testing, there are two scenarios: first, if the wiper is not in the maintenance position, activating the maintenance mode will cause the wiper to first return to its original position at low speed, then wipe at low speed for 800ms to enter the maintenance position; second, if the wiper is already in the returned position, activating the maintenance mode will cause the wiper to directly wipe at low speed for 800ms to reach the maintenance position. The returned position can be, for example, the lowest position the wiper can reach on the windshield, and the maintenance position can be, for example, the highest position the wiper can reach on the windshield.
[0091] In one embodiment of this application, transmitting the load input signal to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test includes:
[0092] The load input signal is transmitted to the front wiper washing module to control the pre-configured washing motor to work, and a test output signal is output when the washing motor is working.
[0093] If the load input signal stops transmitting within the fourth time period, then the washing motor is controlled to stop working within the fourth time period.
[0094] For example, the front wiper washer test includes the following steps: unlock the remote key and switch the power to the ON position; turn on the front wiper washer switch (i.e., slide the front wiper washer down on the load box stand), the front washer motor sprays water, and at this time the front washer motor power indicator light is on; turn off the front wiper washer switch (i.e., slide the front wiper washer to the middle position on the load box stand), the front washer motor stops spraying water, and at this time the front washer motor power indicator light is off.
[0095] In one embodiment of this application, the load input signal is transmitted to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test, including:
[0096] The load input signal is transmitted to the front wiper automatic wiping module, and the rainfall signal transmitted by the load module is received.
[0097] If the rainfall signal matches the preset light rainfall signal, the front wiper is controlled to wipe at the first speed, and a test output signal of the front wiper during wiping is output.
[0098] If the rainfall signal matches the preset heavy rainfall signal, the front wiper is controlled to wipe at the second speed, and a test output signal of the front wiper during wiping is output.
[0099] For example, the automatic wiper function needs to be enabled by modifying the configuration word. The automatic wiper function requires sending a LIN signal to the controller via a CANOE-simulated rain sensor. When the rain sensor detects rain, it sends a wiper speed request signal RLS_Wiper_speed to the controller based on the amount of rain. When RLS_Wiper_speed = 1, the front wipers operate at low speed; when RLS_Wiper_speed = 14, the front wipers operate at high speed; when RLS_Wiper_speed = 0, if the front wipers are in the return position, control of the front wipers is stopped; if the front wipers are not in the return position, control them to return at low speed; when RLS_Wiper_speed equals any other value, it is treated as RLS_Wiper_speed = 0. The testing process is as follows: Enable the automatic wiper function; unlock the remote key and switch the power to ON; send the wiper speed request signal RLS_Wiper_speed = 1 via CANOE, and the wipers will wipe at low speed; send the wiper speed request signal RLS_Wiper_speed = 14 via CANOE, and the wipers will wipe at high speed.
[0100] In one embodiment of this application, transmitting the load input signal to the target wiper function module so that the target wiper function module performs a functional test based on the load input signal and outputs a test output signal during the functional test includes:
[0101] The load input signal is transmitted to the rear wiper automatic wiping module, and the vehicle gear signal transmitted by the pre-configured gear module is received.
[0102] If the vehicle gear position signal is reverse gear, then the rear wiper is controlled, and a test output signal for the rear wiper is output.
[0103] For example, when the front wiper is wiping and the vehicle is shifted into reverse, the rear wiper will automatically wipe once at low speed. The test procedure is as follows: unlock the remote key and switch the power to ON; when the front wiper is wiping at low speed / high speed / intermittent speed, switch the gear from non-R gear to R gear and observe whether the rear wiper automatically wipes once after switching to R gear.
[0104] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
