Description

Technical Field

[0001] The present application relates to the field of vehicle testing, and in particular to a vehicle pedal testing device, method, and equipment. Background Art

[0002] With the increasing penetration of new energy vehicles, vehicle development cycles are shrinking. During vehicle drivability testing, precise adjustment of the accelerator pedal's position is often required. During vehicle energy management test analysis, not only does the position of the accelerator or brake pedal need to be adjusted, but the pedal's depression rate is also sometimes required. Without access to the vehicle's existing CAN protocol, conventional test fixtures are typically fixed to the pedal base. This is achieved by adjusting the fixture's screws with a wrench or by adding shims beneath the pedal bracket to adjust the height and position. Installing shims beneath the pedal bracket can lead to displacement deviations when the driver presses the pedal hard, as the vehicle floor is not a rigid structure. Furthermore, shim thickness varies, making it difficult to accurately position the pedal. If the fixture accidentally falls off, it can become stuck beneath the pedal, posing a safety hazard. Frequent adjustments to the fixture during testing often require the driver to exit the vehicle to adjust the position using bolts. This creates a narrow area beneath the driver's seat, making operation difficult and labor-intensive. Furthermore, harsh environmental conditions (high temperatures, freezing temperatures, rain, and snow) can severely impact adjustment efforts. Furthermore, it's impossible to control the pedal's speed. Furthermore, since many vehicles currently use piano-style pedals, most devices require custom fabrication, making them less versatile. Therefore, a testing device that allows for flexible and precise adjustment of the accelerator pedal's position is urgently needed. Summary of the Invention

[0017] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] First, some technical terms in this application are explained to facilitate those skilled in the art to understand this application.

[0019] (1) CAN (Controller Area Network), a serial communication protocol used in automotive, industrial control and other fields; (2) DBC (Database Can File), a file format used in automotive electronic systems to define controller area network (CAN) communication data. In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0020] The present application provides a vehicle pedal testing device, method and equipment, which can solve the technical problems in the prior art of inaccurate pedal adjustment and inability to adjust the accelerator pedal and brake pedal at the same time.

[0021] Figure 1 A schematic diagram of the structure of the vehicle pedal testing device provided in the embodiment of the present application. Figure 1, an embodiment of the present application provides a vehicle pedal testing device for testing the accelerator pedal and brake pedal of a vehicle to be tested, the vehicle pedal testing device comprising: a support rod 1 for being fixed to the main driving seat of the vehicle to be tested, a support rod fixing seat 11 being fixedly connected to the outer wall of the support rod 1; a first push rod 2, one end of the first push rod 2 is provided with a first panel 21 for abutting the accelerator pedal of the vehicle to be tested, a first fixing seat 22 is sleeved on the outer wall of the first push rod 2, the first fixing seat 22 is rotatably connected to one side of the support rod fixing seat 11, and a locking bolt 4 is provided on the first fixing seat 22 for enabling the first push rod 2 to slide or lock relative to the first fixing seat 22; a second push rod 3, one end of the second push rod 3 is provided with a second panel 31 for abutting the brake pedal of the vehicle to be tested, a second fixing seat 32 is sleeved on the outer wall of the second push rod 3, the second fixing seat 32 is rotatably connected to the other side of the support rod fixing seat 11, and a locking bolt 4 is provided on the second fixing seat 32 for enabling the second push rod 3 to slide or lock relative to the second fixing seat 32.

[0022] During the test, if only the accelerator pedal needs to be adjusted, the second mounting bracket 32 ​​and the support rod mounting bracket 11 do not need to be installed together. If both the accelerator and brake pedals need to be adjusted simultaneously, the second mounting bracket 32 ​​and the support rod mounting bracket 11 can be installed together to achieve simultaneous adjustment of the accelerator and brake pedals. If the accelerator pedal position needs to be adjusted, the driver can directly loosen the locking bolt 4 on the first mounting bracket 22 from inside the vehicle without exiting the vehicle. Then, push the first push rod 2 to adjust the accelerator pedal position through the first panel 21. After adjusting to the desired test position, tighten the locking bolt 4 again to lock the first push rod 2 and secure the accelerator pedal position. The same operation applies to adjusting the brake pedal position.

[0023] Figure 3 Schematic diagram of the vehicle pedal testing device and vehicle installation provided in the embodiment of the present application. Figure 3 In the embodiment of the present application, one end of the support rod 1 is provided with a lower fixing plate 12 for fixing between the seat and the floor of the vehicle to be tested, and the other end of the support rod 1 is provided with an upper fixing plate 13 for abutting against the lower trim panel of the main driver's seat of the dashboard of the vehicle to be tested, wherein the lower fixing plate 12 is movably connected to the support rod 1.

[0024] Specifically, the lower fixing plate 12 and support rod 1 are connected via a universal joint, which allows for relative rotation between the two rods in multiple directions. This connection provides greater flexibility and can accommodate the complex spatial relationships and angular variations between the seats and the floor of different vehicle models. The lower fixing plate 12 is secured to the seat-floor junction, while the upper fixing plate 13 is secured to the lower driver's side dashboard trim with cloth-based tape, preventing the support rod 1 from shaking during testing.

[0025] Figure 2 This is another structural diagram of the vehicle pedal testing device provided in the embodiment of the present application. Figure 2 Furthermore, the support rod 1 includes: a screw 14 and a rod shell 15, one end of the rod shell 15 is fixedly connected to the upper fixed plate 13, and one end of the screw 14 is movably connected to the lower fixed plate 12. The outer surface of the screw 14 is provided with a thread, and the inner wall of the rod shell 15 is provided with a thread matching the outer surface of the screw 14. The rod shell 15 is rotated relative to the screw 14 to adjust the length of the screw 14 extending into the rod shell 15.

[0026] By rotating the rod housing 15 or the lead screw 14, the length of the lead screw 14 extending into the rod housing 15 can be changed, thereby adjusting the overall length of the support rod 1 to accommodate the seat and floor structures of different vehicle models, thereby increasing the applicability of the entire testing device. When the testing device is not in use, the support rod 1 can be adjusted to a shorter length, thereby facilitating transportation and storage of the entire testing device.

[0027] In an embodiment of the present application, the support rod fixing seat 11 includes: a base plate 111, the base plate 111 is vertically fixed to the outer wall of the support rod 1, and a screw housing 113 is fixedly connected to the base plate 111; a screw 112 is fixed in the screw housing 113, and the screw 112 passes through the screw housing 113, wherein one end of the screw 112 is rotatably connected to the first fixing seat 22, and the other end of the screw 112 is rotatably connected to the second fixing seat 32, and the first fixing seat 22 and the second fixing seat 32 can both move on the screw 112 in a direction away from or approaching the screw housing 113.

[0028] The threaded engagement between screw 112 and screw housing 113, along with the mobility of first and second mounting bases 22 and 32 on screw 112, allows for flexible and precise adjustment of the positions of first and second push rods 2 and 3 based on the positions of the accelerator and brake pedals. Furthermore, first and second mounting bases 22 and 32 can rotate about the axis of screw 112, enabling the test device to meet specific angle requirements.

[0029] In the embodiment of the present application, the first panel 21 is movably connected to one end of the first push rod 2 , and the second panel 31 is movably connected to one end of the second push rod 3 .

[0030] Specifically, the first panel 21 and one end of the first push rod 2, and the second panel 31 and one end of the second push rod 3 can be connected by a universal joint, so that the angles of the first panel 21 and the second panel 31 can be flexibly adjusted in multiple directions to better fit the surfaces of pedals of different models and ensure the stability and accuracy of contact.

[0031] In the embodiment of the present application, a first pushing portion 23 is provided at the other end of the first pushing rod 2, and the cross-sectional area of ​​the first pushing portion 23 in the vertical direction is larger than the cross-sectional area of ​​the first panel 21 in the vertical direction. A second pushing portion 33 is provided at the other end of the second pushing rod 3, and the cross-sectional area of ​​the second pushing portion 33 in the vertical direction is larger than the cross-sectional area of ​​the second panel 31 in the vertical direction.

[0032] During the testing of the pedal, the larger cross-sectional area of ​​the pushing part can provide a more stable force application point, allowing the tester or the testing device to transfer the force to the first push rod 2 or the second push rod 3 more evenly, thereby pushing the pedal more effectively, while reducing the possibility of deformation or damage of the first push rod 2 or the second push rod 3 due to frequent use or strong pushing, thereby extending the service life of the first push rod 2 or the second push rod 3.

[0033] In an embodiment of the present application, the vehicle pedal testing device also includes: an adjusting motor 5 electrically connected to the first push rod 2 and a planetary reducer electrically connected to the adjusting motor 5. The outer surface of the first push rod 2 is provided with a rack matching the gear of the planetary reducer. The planetary reducer controls the rate at which the first push rod 2 pushes the accelerator pedal of the vehicle to be tested according to the rotational speed of the adjusting motor 5.

[0034] Figure 4 This is a schematic diagram of the control system for regulating the motor provided in the embodiment of the present application. Figure 4Specifically, the regulating motor 5 is a stepper motor. The pulse generator generates pulse signals to control the speed and position of the stepper motor. These pulse signals are sent to the PUL+ and PUL- pins of the stepper motor controller. The frequency of the pulse signal determines the speed of the stepper motor, while the number of pulses determines the rotation angle of the stepper motor. A direction control signal, provided by the power supply, controls the direction of the stepper motor. This direction control signal is sent to the stepper motor controller via the DIR+ and DIR- pins. When the DIR+ pin is high, the stepper motor rotates in one direction; when the DIR+ pin is low, the stepper motor rotates in the opposite direction. Based on the received pulse signals and direction control signal, the stepper motor controller generates corresponding drive signals to control the operation of the stepper motor. The stepper motor controller sends these drive signals to the two-phase coils of the stepper motor via the A+ / A- and B+ / B- pins, thereby driving the motor. The speed and direction of the stepper motor are determined by the frequency of the pulse signal and the state of the direction control signal.

[0035] The planetary reducer controls the rate at which the first push rod 2 pushes the accelerator pedal of the vehicle under test based on the speed of the regulating motor 5. When the regulating motor 5 is running, its output power is decelerated and torque-increased by the planetary reducer before being transmitted to the gear. The gear meshes with the rack on the first push rod 2, pushing the accelerator pedal. The speed of the regulating motor 5 varies, and the speed transmitted to the gear via the planetary reducer changes accordingly, affecting the movement speed of the first push rod 2 and, therefore, controlling the rate at which the accelerator pedal is pushed.

[0036] In a specific embodiment, the speed range of motor 5 is 32 rpm to 318 rpm, corresponding to a speed of 0.05 m / s to 0.5 m / s. The required torque of motor 5 is greater than 0.3 Nm (including the reduction ratio and safety margin), the holding torque of motor 5 is 1.2 Nm (to ensure low-speed stability), the step angle of motor 5 is 1.8° (200 steps / rev), and the operating current of motor 5 is between 2 A and 4 A. The pulse frequency of the driver must be greater than 16960 Hz, and 100 kHz is actually selected. The driver's subdivision is set to 16 (to balance accuracy and speed and avoid high-frequency noise). The output frequency range of the pulse generator is 1 kHz to 100 kHz, and a 555 timer PWM module is actually used. The speed ratio of the planetary reducer is 5. The DC voltage range of the power supply is 24-48 V, and the rated current is 5 A. The gear module is 1.5, and the number of teeth is 20.

[0037] The embodiment of the present application, through the flexible cooperation between the support rod fixing seat 11, the first fixing seat 22 and the second fixing seat 32, and the sliding and locking functions of the locking bolt 4, can achieve free and precise adjustment of the position of the accelerator pedal and the brake pedal, thereby improving the accuracy and reliability of the test. The support rod 1 of the embodiment of the present application is located in the main driving seat. When the tester adjusts the pedal, he can adjust it directly by manual or electric adjustment without getting off the vehicle, avoiding the operational inconvenience caused by the narrow space under the driving seat. At the same time, it also reduces the adverse effects of harsh environmental conditions on the adjustment work, thereby improving the efficiency and comfort of the test work. At the same time, the embodiment of the present application can achieve pedal adjustment without installing a gasket under the pedal, and it is not easy for the device to accidentally fall off and get stuck under the pedal, causing a safety hazard, effectively ensuring the safety of the test process. At the same time, with the cooperation of the adjustment motor 5 and the planetary reducer, it is possible to achieve precise adjustment of the accelerator pedal push rate, flexibly adapting to various different test requirements.

[0038] In a second aspect, an embodiment of the present application provides a vehicle pedal testing method, wherein a vehicle pedal testing device based on any of the above embodiments tests the accelerator pedal and brake pedal of a vehicle to be tested.

If so, go to S5; if not, go to S6; S5: adjusting the speed of the accelerator pedal. When the adjusted speed of the accelerator pedal meets the preset speed, the test ends. S6: End of test.
