Description

Technical Field

[0001] This application relates to the technical field of commercial vehicles, and particularly to a device for verifying and evaluating the human-machine operation of a pedal system. Background Art

[0002] There are three pedals in a commercial vehicle: the left pedal is the clutch pedal, the middle one is the brake pedal, and the right one is the accelerator pedal. The clutch pedal is used when starting or shifting gears. The clutch is located between the engine and the transmission, and it can connect or disconnect the engine from the transmission. The brake pedal controls the braking system, and when the brake pedal is depressed, the vehicle will decelerate. The accelerator pedal is the pedal used when accelerating. The accelerator pedal does not directly control the fuel injection volume, but controls the throttle opening. After the throttle opening increases, the ECU will detect it, and then the fuel injection volume will increase. When using the clutch pedal, certain skills are required. When starting the vehicle, the semi-clutch skill needs to be used. If the clutch pedal is quickly lifted when starting, the engine will stall.

[0003] The clutch, brake, and accelerator pedals are components that the driver often operates when driving a vehicle. The quality of the three-pedal layout directly affects the ride comfort; the three-pedal layout involves the front and rear positions, angles, heights, pedal forces, pedal strokes, and clearances between the pedals and surrounding components (such as the steering column shroud, instrument panel guard, etc.).

[0004] Currently, the three-pedal layout scheme relies relatively heavily on design experience. In the initial stage of the scheme design, it is only determined through human-machine experience. Subsequently, only the actual feeling evaluation of the scheme can be carried out on the prototype vehicle. If the layout scheme needs to be adjusted later, there are many parts involved in the change and the cycle of part modification is long, resulting in the delay of the development node.

Detailed implementation manners

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0044] See Figure 1 and Figure 2As shown in the figure, an evaluation device for human-machine operation verification of a pedal system is provided in an embodiment of the present application. The device includes a first simulated pedal A and a seat 2. Among them, the first simulated pedal A includes a pedal assembly 1 and an XYZ motion mechanism 3. It should be noted that the X direction refers to the vehicle length direction, the Y direction refers to the vehicle width direction, and the Z direction refers to the vehicle height direction. The pedal assembly 1 includes a skeleton 10, a pedal arm 11, a pedal 12, a resistance simulation mechanism 13, and an angle sensor 14; one end of the pedal arm 11 is rotatably connected to the skeleton 10 through the angle sensor 14, and the other end is connected to the pedal 12. When a developer sits on the seat 2 and steps on the pedal 12 to make one end of the pedal arm 11 rotate around the skeleton 10, the angle sensor 14 can accurately measure the rotation angle of the pedal arm 11, and the pedal stroke can be calculated through the formula "arc length = n * πr / 180, where n is the rotation angle"; one end of the resistance simulation mechanism 13 is connected to the skeleton 10, and the other end is rotatably connected to the pedal arm 11. The resistance simulation mechanism 13 can simulate the resistance received by the developer when stepping on the pedal 12; the XYZ motion mechanism 3 is connected to the skeleton 10 and is used to drive the pedal assembly 1 to move in the X direction, Y direction, and Z direction to adjust the relative position relationship between the pedal assembly 1 and the seat 2; the seat 2 and the pedal assembly 1 are arranged in the X direction.

[0045] In the solution provided by the above embodiment, the developer can use the XYZ motion mechanism 3 to drive the pedal assembly 1 to move in the X direction, Y direction, and Z direction, thereby adjusting the relative position relationship between the pedal assembly 1 and the seat 2 and adjusting the height of the pedal. The resistance simulation mechanism 13 is used to simulate the pedal force, and the angle sensor 14 is used to measure the rotation angle of the pedal arm 11, and then the pedal stroke can be calculated. It can be seen that the device provided by the present application can be used by the developer to evaluate the actual feeling of the pedal system. When the actual feeling is not good, the developer can directly make adjustments on the device. Compared with relying on design experience, the present application can be adjusted in time, shortening the development cycle and thus improving the development efficiency.

[0046] It should be noted that in the solution provided by the above embodiment, the first simulated pedal A is included, and the first simulated pedal A can be used as a clutch simulation pedal, a brake simulation pedal, or an accelerator simulation pedal to perform simulation verification on one of the pedals in the three-pedal system.

[0047] It should be noted that since the pedal arm 11 rotates on the skeleton 10, in order to make the resistance simulation mechanism 13 work better, the resistance simulation mechanism 13 is connected to the pedal arm 11 through a spherical hinge.

[0048] See Figure 1 As shown in the figure, a limit block 15 is also provided on the skeleton 10 to limit the maximum stroke of the pedal arm 11.

[0049] SeeFigure 1 As shown, an angular scale 110 is provided on the framework 10, and a pointer 120 adapted to the angular scale 110 is provided on the pedal arm 11. With the cooperation of the angular scale 110 and the pointer 120, when developers conduct simulation verification, they can roughly read the angle through which the pedal arm 11 rotates.

[0050] To simulate the pedal force, in some preferred embodiments, the specific structure of the resistance simulation mechanism 1 is also provided. Refer to Figure 1 As shown, the resistance simulation mechanism 13 includes a fixed block 130, a moving block 131, a connecting rod 132, and an elastic member 133. The fixed block 130 is provided on the framework 10. The moving block 131 is rotatably connected to the pedal arm 11 through a spherical hinge. One end of the connecting rod 132 is connected to the moving block 131, and the other end of the connecting rod 132 passes through the fixed block 130. The elastic member 133 is provided between the fixed block 130 and the moving block 131. When the pedal arm 11 rotates, it drives the translation of the moving block 131, thereby compressing the elastic member 133.

[0051] For the above-mentioned elastic member 133, there are various choices of materials. For example, as an example, refer to Figure 1 As shown, a spring can be used. Again, as an example, other elastic bodies can also be used, such as elastic polymer materials.

[0052] For the above-mentioned elastic member 133, there are various arrangements with the connecting rod 132. For example, as an example, the connecting rod 132 passes through the elastic member 133. For example, refer to Figure 1 As shown, the spring is sleeved on the connecting rod 132. Again, as an example, the elastic member 133 is located outside the connecting rod 132 and is arranged side by side or at intervals with the connecting rod 132, as long as compression can be carried out.

[0053] To verify different pedal forces, the above-mentioned elastic member 133 can be disassembled, that is to say, the elastic member 133 is detachably connected between the fixed block 130 and the moving block 131.

[0054] By replacing the elastic member 133 with different elastic coefficients, verification of different pedal forces can be carried out.

[0055] To achieve detachability, there are various forms. For example, if the connecting rod 132 is threaded through the elastic member 133, the connecting rod 132 is screwed onto the moving block 131. When replacement is needed, unscrew the connecting rod 132 from the moving block 131. Additionally, since the connecting rod 132 is inserted into the fixed block 130, the connecting rod 132 can be removed from the fixed block 130 to replace the elastic member 133. Another example is that if the elastic member 133 is located outside the connecting rod 132 and arranged side by side or at intervals with the connecting rod 132, slots can be provided on the fixed block 130 and the moving block 131, and both ends of the elastic member 133 are snapped into the slots. When replacement is needed, squeeze the elastic member 133 to make one end contract, so as to disengage from the slot, thereby achieving the purpose of removal.

[0056] To verify whether it is convenient to step on at different angles, the pedal angle can be adjusted as needed. Specifically, as shown in Figure 1 As shown, an angle scale 110 is provided on the pedal arm 11, and a pointer 120 adapted to the angle scale 110 is provided on the pedal 12. The pedal 12 is connected to the pedal arm 11 by bolts. When the angle needs to be adjusted, loosen the bolts, then adjust the pedal 12, check the adjusted angle through the pointer 120, and then tighten to complete the angle adjustment of the pedal 12.

[0057] To achieve three-way adjustment, the specific structure of the XYZ motion mechanism 3 is further provided in the embodiments of the present application. As shown in Figure 1 As shown, the XYZ motion mechanism 3 includes a transverse movement base 30, a first drive assembly 31, a longitudinal movement base 32, a second drive assembly 33, and a third drive assembly 34. Among them, the first drive assembly 31 is connected to the transverse movement base 30 and is used to drive the transverse movement base 30 to move along the X direction. The longitudinal movement base 32 is movably arranged on the transverse movement base 30, and the framework 10 is movably arranged on the longitudinal movement base 32. The second drive assembly 33 is connected to the longitudinal movement base 32 and is used to drive the longitudinal movement base 32 to move along the Y direction on the transverse movement base 30. The third drive assembly 34 is connected to the framework 10 and is used to drive the framework 10 to move along the Z direction on the longitudinal movement base 32.

[0058] Among them, as shown in Figure 1 As shown, the first drive assembly 31 includes a first driver 310, a first worm 311, a first turbine 312, and a first worm seat 313. The first turbine 312 is arranged on the transverse movement base 30. One end of the first worm 311 is connected to the first driver 310, and the other end is rotatably connected to the first worm seat 313, and the first worm 311 meshes with the first turbine 312. There are two first worm seats 313, which are respectively located on both sides of the first turbine 312, and the first worm 311 is connected to the first worm seat 313 through bearings.

[0059] As shown in Figure 1As shown, the second driving assembly 33 includes a second driver 330, a second worm 331, a second turbine 332 and a second worm seat 333. One end of the second worm 331 is connected to the second driver 330, and the other end is rotatably connected to the second worm seat 333, and the second worm 331 meshes with the second turbine 332. There are two second worm seats 333, which are respectively located on both sides of the second turbine 332, and the second worm 331 is connected to the second worm seat 333 through a bearing.

[0060] To drive the longitudinal movement base 32, refer to Figure 1 As shown, there are two arrangement ways for the second turbine 332, the second driver 330 and the second worm seat 333 of the second driving assembly 33.

The second way is: the second turbine 332 is arranged on the longitudinal movement base 32, and the second driver 330 and the second worm seat 333 are both arranged on the transverse movement base 30.

[0061] To enable the longitudinal movement base 32 to move smoothly along the Y direction on the transverse movement base 30, a second slide rail (not shown in the figure) is provided between the longitudinal movement base 32 and the transverse movement base 30.

[0062] Refer to Figure 1 As shown, the third driving assembly 34 includes a third driver 340, a third worm 341, a third turbine 342 and a third worm seat 343. One end of the third worm 341 is connected to the third driver 340, and the other end is rotatably connected to the third worm seat 343, and the third worm 341 meshes with the third turbine 342. There are two third worm seats 343, which are respectively located on both sides of the third turbine 342, and the third worm 341 is connected to the third worm seat 343 through a bearing.

[0063] To drive the frame 10 to adjust the height of the pedal 12, refer to Figure 1 As shown, there are two arrangement ways for the third turbine 342, the third driver 340 and the third worm seat 343 of the third driving assembly 34. The first way is: the third turbine 342 is arranged on the frame 10, and the third driver 340 and the third worm seat 343 are both arranged on the longitudinal movement base 32. The second way is: the third turbine 342 is arranged on the longitudinal movement base 32, and the third driver 340 and the third worm seat 343 are both arranged on the frame 10.

[0064] To drive the frame 10 to move smoothly along the Z direction on the longitudinal movement base 32, a third slide rail 7 is provided between the longitudinal movement base 32 and the frame 10.

[0065] To drive the transverse movement base 30 to move smoothly along the X direction, refer to Figure 1As shown, the device further includes a first slide rail 4 extending in the X direction, and the transverse movement base 30 is slidably disposed on the first slide rail 4.

[0066] The number of the first slide rails 4 can be selected according to actual needs. For example, Figure 1 As shown, there are two first slide rails 4, which are arranged in parallel at intervals, and both ends of the transverse movement base 30 are respectively slidably disposed on the two first slide rails 4.

[0067] In order to facilitate reading the adjusted distance, scales or rulers can be provided on the first slide rail 4, the second slide rail and the third slide rail 7.
