Description

Technical Field

[0001] The present invention belongs to the technical field of automobile component control, and in particular relates to an electronic wiper control method, device, equipment, vehicle and storage medium. Background Art

[0002] At present, the control of the electronic wiper system on the car is relatively redundant. After the vehicle controller receives the wiper switch signal, it forwards the wiper switch signal to the electronic wiper control module after simple logic processing. After the electronic wiper control module receives the wiper switch signal, it controls the electronic wiper through the electronic wiper's built-in controller. Letting the electronic wiper's built-in controller control the electronic wiper is inconsistent with the idea of ​​vehicle controller integration. The control unit is arranged in a scattered manner, which increases the layout space. At the same time, the vehicle controller and the electronic wiper control the wiper system at the same time, which is easy to cause excessive control and lead to dysfunction of the wiper system.

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0038] like Figure 1 As shown, an embodiment of the present application provides an electronic wiper control device 10, which may include a manual wiper switch 11, an electronic wiper 12, a sensor module 13, a vehicle controller 14 and a storage module. The manual wiper switch 11 is used to manually control the electronic wiper 12 to move in different gears, and the vehicle controller 14 is used to automatically control the electronic wiper 12 to move in different gears, thereby reducing the layout space of the wiper controller.

[0039] In this embodiment, when controlling the operation of the electronic wiper 12, the source of the electronic wiper control signal of the vehicle is first determined, and the source of the electronic wiper control signal sends a control instruction to the vehicle controller 14. The sensor module 13 collects environmental information, and the vehicle controller 14 analyzes the environmental information to determine whether to execute the control instruction. The vehicle controller 14 integrates the control part of the electronic wiper 12, optimizes the control method of the electronic wiper 12, and reduces control redundancy.

[0040] It can be understood that when the power supply of the wiper system is valid and the electronic wiper 12 is activated, the electronic wiper sensor part timely collects the electronic wiper wiper angle signal, wiper direction signal, wiper speed signal, etc., and sends them to the wiper control module integrated in the vehicle controller 14 in real time through the bus. The wiper control module can form a closed logic loop of the electronic wiper 12 control by analyzing the wiper angle signal, wiper direction signal, wiper speed signal, etc., and correct the deviation of the electronic wiper 12 control in time.

[0041] The storage module stores a computer program. When the computer program is executed by the vehicle controller 14, the electronic wiper control device 10 can execute corresponding steps in the following electronic wiper control method.

[0042] like Figure 2 As shown, the present application also provides an electronic wiper control method. The electronic wiper control method may include the following steps:

[0043] Step 110: The processing module determines the state of the electronic wiper 12 and obtains a determination result;

[0044] Step 120: determining a source of an electronic wiper control signal according to the determination result, wherein the source of the electronic wiper control signal issues a control instruction;

[0045] Step 130: the sensor module 13 collects environmental information and sends the environmental information to the vehicle controller 14;

[0046] Step 140: According to a preset algorithm, the vehicle controller 14 analyzes the environmental information to determine whether the vehicle controller 14 executes the control instruction.

[0047] In the above embodiment, when controlling the operation of the electronic wiper, the source of the electronic wiper control signal of the vehicle is first determined, and the source of the electronic wiper control signal sends a control instruction to the vehicle controller 14, the sensor module 13 collects environmental information, and the vehicle controller 14 analyzes the environmental information to determine whether to execute the control instruction. The vehicle controller 14 integrates the control part of the electronic wiper, optimizes the control method of the electronic wiper 12, and reduces control redundancy.

[0048] As an optional implementation manner, the processing module determines the state of the electronic wiper and obtains the determination result, including:

[0049] The vehicle controller 14 communicates end-to-end with the sensor module 13, and determines that there is no rain sensor at this time, and the rain sensor flag is 0;

[0050] Alternatively, it is determined that there is a rain sensor at this time, and the rain sensor flag is 1.

[0051] In this embodiment, the vehicle controller 14 communicates with the sensor module 13 and controls the rain sensor flag by detecting whether there is a rain sensor in the sensor module 13. If there is a rain sensor, the rain sensor flag is 1, otherwise, the rain sensor flag is 0.

[0052] As an optional implementation manner, according to the determination result, determining the source of the electronic wiper control signal, the source of the electronic wiper control signal issuing a control instruction, comprises:

[0053] When the rain sensor flag is 0, the manual wiper switch 11 serves as the source of the electronic wiper control signal, and the manual wiper switch 11 issues a control instruction;

[0054] Alternatively, when the rain sensor flag is 1, the vehicle controller 14 serves as the source of the electronic wiper control signal, and the vehicle controller 14 issues a control instruction.

[0055] In this embodiment, when it is determined that there is no rain sensor, the manual wiper switch 11 is used as the source of the electronic wiper control signal, and a control instruction is issued through the manual wiper switch 11; when it is determined that there is a rain sensor, the vehicle controller 14 is used as the source of the electronic wiper control signal, and a control instruction is issued according to the rainfall signal collected by the rain sensor to automatically control the electronic wiper.

[0056] As an optional implementation, the sensor module 13 collects environmental information and sends the environmental information to the processing module;

[0057] The sensor module collects the door opening and closing signals, vehicle speed signals and temperature signals of the vehicle respectively, and sends the collected door opening and closing signals, vehicle speed signals and temperature signals to the vehicle controller 14 .

[0058] In this embodiment, the sensor module collects the door opening and closing signals, vehicle speed signals and temperature signals when the vehicle is running, and the vehicle controller 14 analyzes the running status of the vehicle.

[0059] As an optional implementation, according to a preset algorithm, the vehicle controller 14 analyzes the environmental information to determine whether the vehicle controller 14 executes the control instruction, including:

[0060] When the door signal is on, the vehicle controller 14 controls the electronic wiper to operate only at a low speed; when the door signal is off, the vehicle controller 14 controls the electronic wiper 12 to operate according to the control instruction;

[0061] Alternatively, when the vehicle speed signal is within a first preset value, the vehicle controller 14 controls the electronic wiper 12 to operate only at a low speed; when the vehicle speed signal exceeds the first preset value, the vehicle controller 14 controls the electronic wiper 12 to operate according to the control instruction;

[0062] Alternatively, when the temperature signal is within a second preset value, the vehicle controller 14 controls the electronic wiper 12 to run only at a low speed; when the temperature signal exceeds the second preset value, the vehicle controller 14 controls the electronic wiper 12 to run according to the control instruction.

[0063] In this embodiment, when a door opening signal is detected, the car is in a stopped state, and the vehicle controller 14 controls the electronic wiper 12 to run only at a low speed to save power; when a door closing signal is detected, the car may be in a driving state, and the vehicle controller 14 controls the electronic wiper 12 to run according to the control instruction to ensure driving safety.

[0064] When it is detected that the vehicle speed signal is lower than the first preset value, the vehicle speed is very low, and the vehicle controller 14 controls the electronic wiper 12 to run only at a low speed to save power; when it is detected that the vehicle speed signal exceeds the first preset value, the car is driving normally, and the vehicle controller 14 controls the electronic wiper 12 to run according to the control instruction to ensure driving safety.

[0065] It is detected that the temperature signal is lower than the second preset value, which is 0°C. When the temperature is lower than 0°C and there is snow and ice outside, the vehicle controller 14 controls the electronic wiper 12 to run only at a low speed. When the temperature signal exceeds the second preset value, the vehicle controller 14 controls the electronic wiper 12 to run according to the control instruction to ensure driving safety.

[0066] As an optional implementation, during the process of the vehicle controller 14 controlling the electronic wiper 12 to work, the vehicle controller 14 and the electronic wiper 12 send messages to each other within each preset time step. When the vehicle controller does not receive the return message from the electronic wiper, it is determined that the electronic wiper communication is abnormal, and the communication fault protection mechanism is activated.

[0067] In this embodiment, the vehicle controller 14 communicates with the electronic wiper 12 through the LIN bus. When the electronic wiper communication is determined to be abnormal, if the vehicle speed signal is 0 km / h at this time, the electronic wiper 12 is in the first mode, and the electronic wiper 12 stops moving after wiping twice and stops at the parking position to enter the sleep mode; if the vehicle speed signal is greater than 0 km / h at this time, the vehicle is driving normally, and the electronic wiper 12 enters the second mode. The electronic wiper 12 will maintain the following wiping strategy until the battery is exhausted or the vehicle controller 14 receives a valid LIN signal again: the vehicle controller 14 records the current movement speed of the electronic wiper 12, and the vehicle controller 14 controls the electronic wiper 12 to run at the current movement speed for 3 minutes, downshift one gear to run for 3 minutes, and then downshift one gear to run for 3 minutes, and then return to the highest gear after reaching the lowest gear, until it returns to the current movement speed and cycles, and the interval time between each gear shift is 4S to ensure driving safety.
