Description

Technical Field

[0001] This invention relates to the field of intelligent vehicle technology, and in particular to an automotive transmission with intelligent speed control function and its method. Background Technology

[0002] Pure electric vehicles refer to a new generation of clean energy vehicles that use onboard power sources and electric motors to drive the wheels, resulting in minimal environmental impact. In single-speed pure electric vehicles, the gear ratio is fixed, and the output speed can only be controlled by changing the motor speed. The motor speed is controlled by changing the current. To adapt to frequent speed changes during use, the motor needs to maintain high reliability, adjustment precision, and fast response speed, placing high demands on the motor and affecting its lifespan. With the drive motor parameters fixed, the output torque and output speed range are relatively small, thus limiting the maximum vehicle speed and climbing performance.

[0003] Chinese patent CN204647168U discloses a 2-speed dual-clutch automatic transmission and a vehicle equipped with the transmission. This 2-speed dual-clutch automatic transmission includes a first clutch, a second clutch, an input shaft assembly, and a driven shaft assembly. The input shaft assembly drives the first and second clutches; the driven shaft assembly drives the differential input gear. When in different gears, the driven shaft assembly is driven by either the first or second clutch. The 2-speed dual-clutch automatic transmission, by setting different clutches for the power generated by the electric motor, mechanically adjusts the gears of the single power source generated by the electric motor, avoiding the problem of poor hill-climbing performance caused by controlling vehicle speed solely by the magnitude of the motor current.

[0004] While this application addresses the problems in the background technology to some extent, it has the following issues: 1. The automatic shifting function of the dual-clutch automatic transmission automatically shifts gears after shifting, requiring manual control of the shifting; 2. In some emergency situations, if human judgment is inaccurate, acceleration errors may occur, leading to adverse consequences, and intelligent control cannot be achieved. Summary of the Invention

[0005] The purpose of this invention is to provide an automotive transmission and method with intelligent speed control. A control component is connected to the transmission body, and this control component is connected to the steering wheel via a data acquisition component. When the driver feels tension and grips the steering wheel tightly, their hand rests on the steering wheel corresponding to a second detection element, causing the steering wheel to slightly sink. The second detection element converts the pressure into an electrical signal, which is transmitted to a signal receiving module. After the signal conversion module, the signal is transmitted to the main control module. When the driver turns or the road conditions are poor, the main control module judges the signal and responds through an output module. It can intelligently adjust the working state of the transmission body according to the driver's driving state, achieving automatic speed adjustment, suitable for novice drivers. A learning module is set on the control panel. First, the learning module acquires the driver's driving habits. After driving, the learning module re-analyzes the detection data from the first and second detection elements during the driving process, re-determines the thresholds based on the driver's driving habits, and continuously updates the data to adapt to the continuous improvement of the driver's driving skills, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a car transmission with intelligent speed control function, comprising a transmission body, a control component, a differential, and a steering wheel. A support frame is provided on one side of the transmission body, and the control component is fixedly connected to the upper end of the support frame.

A control panel is provided on one side of the mounting panel, and the control panel is electrically connected to a data acquisition component. Oil control components are respectively provided at both ends of the mounting panel, and the oil control components are electrically connected to the control panel. The oil control components are connected to the transmission body via pipes. The data acquisition component is connected to the steering wheel and includes a first detection element, a second detection element, and a third detection element. The first, second, and third detection elements are respectively electrically connected to the control panel. A steering shaft is provided at the lower end of the steering wheel, and a third detection element is mounted on the steering shaft. First detection elements are symmetrically arranged on both sides of the steering wheel. Built-in grooves are provided on the upper and lower sides of the steering wheel's grip area, and second detection elements are disposed within these grooves.

[0007] Preferably, the transmission body includes a housing, a drive motor, a first clutch, a second clutch, an input shaft, and a driven shaft. The drive motor is located on one side of the housing, and the output end of the drive motor is connected to the input shaft. The first clutch and the second clutch are mounted on the input shaft. A first-speed drive gear and a second-speed drive gear are respectively mounted on one side of the first clutch and the second clutch. A first-speed reduction gear, a second-speed reduction gear, and a main reduction gear are mounted on the driven shaft. The main reduction gear meshes with the differential, and the first-speed reduction gear and the second-speed reduction gear mesh with the first-speed drive gear and the second-speed drive gear, respectively.

[0008] Preferably, the oil control assembly includes a hydraulic valve block and an electric oil pump, the hydraulic valve block and the electric oil pump are connected, the electric oil pump is connected to a first clutch and a second clutch through a pipeline, and the electric oil pump is electrically connected to the control panel.

[0009] Preferably, the control panel includes a main control module, a signal receiving module, a signal conversion module, a storage module, a power supply module, an output module, and a learning module. The main control module is electrically connected to the signal conversion module, the storage module, the power supply module, the output module, and the learning module. The output module is electrically connected to the electric oil pump. The signal receiving module is electrically connected to the signal receiving module and the learning module. The output terminal of the signal receiving module is electrically connected to the first detection element, the second detection element, and the third detection element.

[0010] Preferably, the first and second detection elements are pressure detection elements, and a support spring is provided on one side of the second detection element, and the other side of the support spring is fixedly connected to the side wall of the built-in groove.

[0011] Preferably, the first and second detection elements are disposed at the conventional hand grip position corresponding to the steering wheel, and the first and second detection elements are provided with multiple detection areas.

[0012] Preferably, the third detection element is a torque detection element.

[0013] Another technical problem to be solved by the present invention is to provide a method for using an automotive transmission with intelligent speed control function, comprising the following steps:

[0014] S1: Before driving the vehicle, the driver's driving habits are learned through the learning module. The first and second detection elements obtain the pressure value of the driver's hands on the steering wheel and transmit it to the learning module through the signal receiving module. The learning module records the initial value, marks it, and then stores it through the storage module.

[0015] S2: During driving, the first detection element, the second detection element and the third detection element constantly monitor the pressure value and torque value of the corresponding position of the steering wheel during the driver's driving process, and transmit the electrical signal to the main control module through the signal receiving module;

[0016] S3: The main control module compares the signal value with the stored value in the storage module, makes a judgment, and controls the electric oil pump to work through the output module;

[0017] S4: When the electric oil pump drives the first clutch to work, the second clutch disengages from the second gear reduction gear and does not generate driving force on the driven shaft. The first clutch transmits the power generated from the input shaft to the first gear drive gear corresponding to the first gear reduction gear, making its speed the same as the input shaft. Then the first gear reduction gear meshes with the first gear drive gear, transmitting the power input from the input shaft to the driven shaft. The rotation generated by the driven shaft drives the main reduction gear set on the driven shaft. The main reduction gear meshes with the corresponding gear in the differential through the corresponding gear, outputting the power generated by the drive motor and driving the car. The working principle of the electric oil pump driving the second clutch is the same.

[0018] Preferably, the learning module's operation includes the following steps:

[0019] S11: Before the first drive, a driving record is made. The first and second detection elements acquire the pressure value and grip position of the driver's hands on the steering wheel, and transmit them to the learning module through the signal receiving module. The learning module records the initial values ​​and marks the driver.

[0020] S12: During driving, the first and second detection elements monitor the pressure value of the driver's hands gripping the steering wheel. When the pressure value exceeds the threshold, it is determined that the driver is experiencing abnormal road conditions. When the first and third detection elements simultaneously detect an increase in the value, it indicates that the driver is turning. In case of abnormal road conditions or turning, the main control module will decelerate the first or second clutch through the output module. Conversely, when the detection element detects a value less than the threshold, it indicates that the driving road conditions are good. The learning module only records the detection data.

[0021] S13: After driving ends, the learning module re-analyzes the detection data of the first and second detection elements during driving and redetermines the threshold based on the driver's driving habits;

[0022] S14: When different people drive the vehicle, the system retrieves the corresponding driver record from the storage module based on the different gripping force and gripping position of the driver on the steering wheel.

[0023] Preferably, the threshold includes an upper threshold and a lower threshold, both of which are set based on the grip strength of the driver when driving without any abnormalities.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention proposes an automotive transmission and method with intelligent speed control function. A control component is connected to the transmission body, and the control component is connected to the steering wheel through a data acquisition component. When the driver feels tension and grips the steering wheel tightly, their hand rests on the steering wheel corresponding to the second detection element, causing the steering wheel to slightly sink. The second detection element converts the pressure into an electrical signal and transmits it to the signal receiving module. After the signal conversion module, it is transmitted to the main control module. When the driver turns or the road conditions are poor, the main control module judges the signal and responds through the output module. It can intelligently adjust the working state of the transmission body according to the driver's driving state, realizing automatic speed adjustment, which is suitable for novice drivers. The control panel is equipped with a learning module. First, the learning module acquires the driver's driving habits. After driving, the learning module re-analyzes the detection data of the first and second detection elements during the driving process, redetermines the thresholds according to the driver's driving habits, and continuously updates the data to adapt to the continuous updates in the driver's driving skills.

The hydraulic valve block 231 and the electric oil pump 232 are connected. The electric oil pump 232 is connected to the first clutch 13 and the second clutch 14 via pipes. The electric oil pump 232 is electrically connected to the control panel 22. The oil control component 23 has two sets, one for the first clutch 13 and the other for the second clutch 14. 3. The second clutch 14 is in operation. The control panel 22 includes a main control module 221, a signal receiving module 222, a signal conversion module 223, a storage module 224, a power supply module 225, an output module 226, and a learning module 227.

[0037] Please see Figures 4-6The data acquisition component 4 is connected to the steering wheel 5. The data acquisition component 4 includes a first detection element 41, a second detection element 42, and a third detection element 43.

A steering shaft 51 is provided at the lower end of the steering wheel 5, and the third detection element 43 is installed on the steering shaft 51.

In use, when the driver feels tension and grips the steering wheel 5 tightly, the hand grips the steering wheel 5 corresponding to the second detection element 42, causing the steering wheel 5 to sink slightly.

[0038] Please see Figures 7-8 To better demonstrate the implementation process of an automotive transmission with intelligent speed control, this embodiment presents a method for using an automotive transmission with intelligent speed control, including the following steps:

[0039] Step 1: Before driving the vehicle, the driver's driving habits are acquired through the learning module 227. The first detection element 41 and the second detection element 42 acquire the pressure value of the driver's hands gripping the steering wheel 5 and transmit it to the learning module 227 through the signal receiving module 222. The learning module 227 records the initial value, marks it, and then stores it through the storage module 224.

[0040] Step 2: During driving, the first detection element 41, the second detection element 42 and the third detection element 43 constantly monitor the pressure value and torque value of the corresponding position of the steering wheel 5 during the driver's driving process, and transmit the electrical signal to the main control module 221 through the signal receiving module 222;

[0041] Step 3: The main control module 221 compares the signal value with the stored value in the storage module 224, makes a judgment, and controls the electric oil pump 232 to work through the output module 226.

[0042] Step 4: When the electric oil pump 232 drives the first clutch 13 to work, the second clutch 14 disengages from the second gear reduction gear 162 and does not generate driving force on the driven shaft 16. The first clutch 13 transmits the power generated from the input shaft 15 to the first gear drive gear 131 corresponding to the first gear reduction gear 161, making its speed the same as that of the input shaft 15. Then, the first gear reduction gear 161 meshes with the first gear drive gear 131, transmitting the power input from the input shaft 15 to the driven shaft 16. The rotation generated by the driven shaft 16 drives the main reduction gear 163 set on the driven shaft 16. The main reduction gear 163 meshes with the corresponding gear in the differential 3 through the corresponding gear, outputting the power generated by the drive motor 12 and driving the car to run. The working principle of the electric oil pump 232 driving the second clutch 14 is the same.

[0043] The working process of learning module 227 includes the following steps:

[0044] S11: Before the first drive, a driving record is made. The first detection element 41 and the second detection element 42 acquire the pressure value and grip position of the driver's hands on the steering wheel 5, and transmit them to the learning module 227 through the signal receiving module 222. The learning module 227 records the initial value and marks the person.

[0045] S12: During driving, the first detection element 41 and the second detection element 42 monitor the pressure value of the driver's hands gripping the steering wheel 5. When the pressure value exceeds the threshold, it is determined that the driver is experiencing abnormal road conditions. When the first detection element 41 and the third detection element 43 simultaneously detect an increase in value, it indicates that the driver is turning. In case of abnormal road conditions or turning, the main control module 221 will decelerate the first clutch 13 or the second clutch 14 through the output module 226. Conversely, when the detection element detects a value less than the threshold, it indicates that the driving road conditions are good. The learning module 227 only records the detection data. The threshold includes an upper threshold and a lower threshold. Both the upper threshold and the lower threshold are set according to the driver's grip force when driving without abnormalities.

[0046] S13: After driving ends, the learning module 227 re-analyzes the detection data of the first detection element 41 and the second detection element 42 during driving, and redetermines the threshold based on the driver's driving habits.

[0047] S14: When different people drive the vehicle, the corresponding driver record is retrieved from the storage module 224 based on the different gripping force and gripping position of the driver on the steering wheel 5.

[0048] In summary, this intelligent speed control automotive transmission and its method include a control component 2 connected to the transmission body 1. The control component 2 is connected to the steering wheel 5 via a data acquisition component 4. When the driver feels tension and grips the steering wheel 5 tightly, their hand rests on the steering wheel 5 corresponding to the second detection element 42, causing the steering wheel 5 to slightly sink. The second detection element 42 converts the pressure into an electrical signal and transmits it to the signal receiving module 222. After passing through the signal conversion module 223, the signal is transmitted to the main control module 221. When the driver turns or the road conditions are poor, the main control module 221 judges the signal and responds through the output module 226. It can intelligently adjust the working state of the transmission body 1 according to the driver's driving state to achieve automatic speed adjustment, which is suitable for novice drivers. The control panel 22 is equipped with a learning module 227. The learning module 227 first acquires the driver's driving habits. After driving, the learning module 227 re-analyzes the detection data of the first detection element 41 and the second detection element 42 during the driving process, redetermines the threshold according to the driver's driving habits, and continuously updates the data to adapt to the continuous updates of the driver's driving skills.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A method of using an automotive transmission with intelligent speed control function as described in claim 5, characterized in that, Includes the following steps: S1: Before driving the vehicle, the driver first obtains the driver's driving habits through the learning module (227). The first detection element (41) and the second detection element (42) obtain the pressure value of the driver's hands gripping the steering wheel (5) and transmit it to the learning module (227) through the signal receiving module (222). The learning module (227) records the initial value, marks it, and then stores it through the storage module (224). S2: When driving, the first detection element (41), the second detection element (42) and the third detection element (43) constantly monitor the pressure value and torque value of the corresponding position of the steering wheel (5) during the driver's driving process, and transmit the electrical signal to the main control module (221) through the signal receiving module (222). S3: The main control module (221) compares the signal value with the stored value in the storage module (224) to make a judgment, and controls the electric oil pump (232) to work through the output module (226); S4: When the electric oil pump (232) drives the first clutch (13) to work, the second clutch (14) separates from the second gear reduction gear (162) and does not generate driving force on the driven shaft (16). The first clutch (13) transmits the power generated from the input shaft (15) to the first gear drive gear (131) corresponding to the first gear reduction gear (161), so that its speed is the same as that of the input shaft (15). Then the first gear reduction gear (161) meshes with the first gear drive gear (131) and transmits the power input from the input shaft (15) to the driven shaft (16). The rotation generated by the driven shaft (16) drives the main reduction gear (163) set on the driven shaft (16). The main reduction gear (163) meshes with the corresponding gear in the differential (3) through the corresponding gear, outputting the power generated by the drive motor (12) and driving the car to run.
