Description

Technical Field

[0001] This invention relates to the field of automotive braking system technology, specifically to an automatic adjustment method and device for IBC installation mode in a vehicle state. Background Art

[0002] With the development of the automotive industry, Integrated Brake Control (IBC) has become the mainstream trend in automotive braking technology development, based on meeting the global automotive industry's demands for emission reduction, safety, and autonomous driving. IBC replaces the Electronic Stability Control system with a single integrated unit, replacing the numerous subsystems in traditional gasoline vehicles, including the Electronic Stability Control system, vacuum booster and related wiring harnesses, sensors, switches, electronic controllers, and vacuum pumps, thus reducing weight by 25% to 30%.

[0003] Due to the high degree of integration of the IBC (combining the drive motor, hydraulic valve body, controller, and other components into a single unit), its individual weight is relatively high, typically around 6 kg. Due to the mandatory requirements of braking functionality, the IBC must be mounted on both sides of the front bulkhead along with the brake pedal. The front bulkhead is a large, stamped sheet metal part, and to meet the lightweight requirements of new energy vehicles, its thickness is strictly limited (currently, the front bulkhead thickness of new energy vehicles is more than 40% thinner than that of traditional fuel vehicles).

[0004] When a heavy IBC (Integrated Brake Controller) component is mounted on a thin, low-rigidity front bulkhead component, the IBC component's mounting mode is low. Under the influence of engine and road surface excitation, the IBC is prone to significant vibration, which is then transmitted to the pedals (accelerator and brake pedals) and steering wheel, ultimately being perceived by the user and causing complaints. Therefore, improving the IBC's mounting mode at the vehicle boundary is an important issue in the development of new energy vehicles.

[0005] In the prior art, one approach is to add lateral and vertical supports between the brake pedal and the CCB and the front bulkhead, respectively. However, this method has the following drawbacks:

[0006] 1) Poor installation process: The new bracket is located inside the cab below the steering wheel, where the working space is small, making installation difficult; this part is connected to multiple parts, resulting in a long installation dimension chain and a high risk of batch installation failure.

[0007] 2) Poor versatility of the solution: Most vehicle models do not have diagonal bracing parts that connect the IP crossbeam to the front bulkhead. At the same time, the rigidity of other parts of the pedal is low, and there is a lack of environmental components for the installation of lateral brackets, so the solution cannot be applied. Different vehicle models have different distances between the brake pedal and the lower crossbeam of the windshield. The longer the vertical bracket installation distance, the lower the support rigidity provided to the IBC and the worse the effect.

[0008] Another method to improve the IBC mounting mode is to add a mounting bracket between the IBC and the lower crossbeam of the front bulkhead, increasing the overall vehicle mounting rigidity of the IBC and thus improving its mounting mode. However, this method suffers from poor commercial feasibility: IBC parts are generally modular components from suppliers, and adding an additional bracket involves production line modifications and adjustments.

[0009] Therefore, a new technical solution is needed to solve the above problems. Summary of the Invention

[0010] The purpose of this invention is to provide an automatic adjustment method and device for improving the vehicle installation mode of IBC and avoiding resonance with excitation sources such as the engine, road surface, and transmission system under vehicle conditions.

[0020] Preferably, the value of A is in the range of 3 to 5.

[0021] Preferably, the value of B is in the range of 3 to 5.

[0022] In some alternative embodiments of the present invention, the permissible vibration intensity K i The frequency-intensity table is obtained from the frequency-intensity table; the steps for establishing the frequency-intensity table include:

[0023] The adjustable frequency range of the IBC is divided into N levels. Based on the subjective evaluation results of the actual vehicle brake pedal vibration and combined with the vibration perception curve, the permissible vibration intensity is determined for the N levels and a frequency-intensity table is drawn.

[0024] In some optional embodiments of the present invention, based on the pedal position or pedal force signal, when the pedal is in the depressed state, the current vibration frequency f and vibration intensity K of the brake pedal are collected.

[0025] In some optional embodiments of the present invention, the method further includes the following steps:

[0026] Set the vibration acquisition and judgment time condition: if the vibration intensity K is greater than K for 30 consecutive seconds. i If so, then the modal adjustment action will be executed.

[0027] In some optional embodiments of the present invention, after adjustment is completed, the vibration intensity K' of the brake pedal is re-acquired and compared with the permissible vibration intensity K. i In contrast, when K≤K i Confirm the accuracy of the location of the auxiliary support points.

[0031] A driving component is used to drive the slider to slide along the base to adjust the position of the auxiliary support point of the IBC drive motor;

[0032] The control unit is used to control the drive component to move the slider according to the method described in the first aspect, and automatically adjust the position of the auxiliary support point of the IBC drive motor.

[0033] In some alternative embodiments of the present invention, the slider is provided with an arc surface adapted to the outer wall of the IBC motor, and the slider provides normal auxiliary support to the cylindrical surface of the IBC motor through the arc surface.

[0034] In some alternative embodiments of the present invention, the surface of the arc surface is provided with an elastic block that conforms to its shape.

[0035] In some optional embodiments of the present invention, the base is provided with a dovetail groove, and the slider is provided with a limiting sliding part adapted to the limiting groove; the base and the slider are constrained by the dovetail groove slide, so that the slider can only move along the length direction of the dovetail groove.

[0037] The beneficial effects of the present invention are:

[0038] This invention achieves real-time dynamic adjustment of the IBC installation mode by adding an adjustable auxiliary support device at the IBC location, combined with vibration detection and automatic control strategies. This effectively avoids resonance between the IBC and other excitation sources in the vehicle, and has low implementation cost and strong versatility.

[0039] This invention can completely and actively avoid vibration problems in new energy vehicles caused by resonance between the installation mode of the integrated brake controller and the excitation source. This invention is highly feasible, has a simple structure, high reliability, and low cost, and possesses the potential for exploring and applying new technologies in the active control of new energy vehicles.

[0041] 2. This invention achieves real-time dynamic adjustment of the IBC installation mode by adding an adjustable auxiliary support device to the end of the IBC drive motor and combining vibration detection and automatic control strategies.

[0055] The technical solutions (including preferred technical solutions) of the present invention will be further described in detail below with reference to the accompanying drawings and by way of listing some optional embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0056] Integrated Brake Controller (IBC): It mainly consists of four parts: reservoir, hydraulic control valve body, pedal force input mechanism, and motor drive mechanism. It replaces the electronic stability control system with an integrated unit, replacing the entire vehicle braking system in traditional fuel vehicles, which consists of numerous subsystems such as electronic stability control system, vacuum booster and related wiring harnesses, sensors, switches, electronic controllers and vacuum pumps, reducing weight by 25% to 30%.

[0057] Installation stiffness: The ability of a component to resist deformation under external force after it has been installed and fixed. Stiffness = force / deformation displacement, unit N / mm.

[0058] Vehicle status: The boundary conditions of a drivable vehicle assembled from systems such as body, chassis, electronic control, and accessories.

[0059] Installation mode: The inherent vibration characteristics exhibited by a component after it has been installed and fixed to the surrounding environment by fastening bolts, clips, hinges and other connecting parts, measured in Hz.

[0060] The initial installation method of the IBC assembly on the vehicle is a cantilever beam structure, and its simplified mechanical diagram is as follows: Figure 1 As shown. The main mass m of the assembly is concentrated at the cantilever end. Under this mounting method, its upper limit of natural frequency is...

[0061]

[0062] Therefore, without changing the stress state, it is difficult to significantly improve the installation mode of the IBC assembly simply by increasing the dynamic stiffness of the IBC mounting point. In the formula, E is the elastic modulus of the beam manufacturing material, and I is the moment of inertia of the beam section, both of which are inherent properties of the beam and can be considered as unchangeable characteristic parameters in the simplified IBC model of this example.

[0063] Example 1

[0064] like Figure 2 As shown, this embodiment provides an automatic adjustment device for IBC installation mode in a vehicle state, including a base 1, a slider 2, an elastic block 3, a drive component, and a control unit.

[0065] The base 1 is fixedly connected to the front bulkhead of the vehicle body by bolts. The base 1 is provided with a guide groove with a dovetail-shaped cross section.

[0066] The lower part of the slider 2 is provided with a limiting sliding part adapted to the dovetail groove, and the upper part is provided with an arc-shaped support surface adapted to the housing of the IBC drive motor. The radius of curvature of the arc-shaped support surface is the same as the radius of the cylindrical surface of the motor housing. The slider 2 is embedded in the guide groove of the dovetail groove base 1 through the limiting sliding part, and can slide back and forth along the length of the guide groove.

[0067] In some embodiments of the present invention, the purpose of the slider 2 is to increase the overall support stiffness of the IBC, so the support position is not limited to the IBC drive motor. If the IBC valve body structure and space permit, the slider 2 can also achieve a similar effect by supporting the valve body.

[0068] The shape of the elastic block 3 is consistent with the arc-shaped support surface of the slider 2. It is fixed to the arc-shaped support surface of the slider 2 by adhesive and is used to buffer the contact between the slider 2 and the housing of the IBC drive motor.

[0069] In some embodiments of the present invention, the elastic block 3 is a rubber block, which can be fixed to the slider 2 by an adhesive, or by a fastening bolt, a convex-concave fit structure, or other means.

[0070] The elastic block 3 can: ① increase the IBC, in some embodiments of the present invention, increase the contact area between the IBC drive motor and the slider 2, making the overall structure of the IBC more stable; ② reduce vibration, prevent the vibration of the IBC body from being transmitted to the vehicle body through the bracket; ③ protect the IBC components, as dry friction between rigid parts is more likely to cause wear during the sliding process of the slider 2.

[0071] The drive components include an adjusting rod 4 and a motor 5.

[0072] The adjusting rod 4 is rotatably connected to the base 1, and its position relative to the base 1 remains unchanged. One end of the adjusting rod 4 is connected to the drive unit of the motor 5, and the other end is threadedly connected to the slider 2. The motor 5 is electrically connected to the control unit, and drives the adjusting rod 4 to rotate forward or backward according to the signal of the control unit. Through the threaded transmission, the slider 2 is moved up and down, thereby adjusting the contact position between the slider 2 and the housing of the IBC drive motor.

[0073] The control unit receives signals from the pedal position sensor and the pedal vibration sensor. Based on the pedal position and force sensor signals, it determines that the pedal is depressed and activates the controller. It collects the pedal vibration sensor signal and compares it with a table to determine if the IBC installation mode needs adjustment. The control unit controls the drive component to move the slider according to the method described in Example 2, automatically adjusting the position of the IBC auxiliary support point.

[0074] The control unit controls the movement of slider 2 through the drive component, adjusts the position of slider 2, and thereby adjusts the support stiffness of slider 2 for IBC, so as to achieve the target requirement for the overall vehicle installation stiffness of IBC.

[0075] In some embodiments of the present invention, the motor 5 is a stepper motor.

[0076] Example 2

[0077] This embodiment provides an automatic adjustment method for the installation mode of an integrated brake controller in a vehicle state, including the following steps:

[0078] Determine the adjustable frequency range and vibration intensity standard for IBC installation modes:

[0079] Based on the characteristics of the vehicle engine's operating frequency range, road surface excitation frequency range, and transmission system excitation frequency range, and considering the principle that the IBC needs to avoid certain frequencies from these excitation sources, the adjustable frequency range of the IBC installation mode is determined to be f. min ~f max .

[0080] The adjustable frequency range of the IBC is divided into N levels. Based on the subjective evaluation results of the actual vehicle brake pedal vibration and combined with the vibration perception curve, the permissible vibration intensity is determined for the N levels and a frequency-intensity table is drawn. The frequency-intensity table is shown in Table 1.

[0081] Table 1

[0082] Vibration frequency / Hz <![CDATA[f min ]]> … <![CDATA[f i ]]> … <![CDATA[f max ]]> Vibration intensity / dB <![CDATA[K1]]> … <![CDATA[K i ]]> … <![CDATA[K n ]]>

[0083] Real-time monitoring of pedal vibration status:

[0084] The pedal position sensor detects the pedal state. When the pedal is detected to be depressed, the vibration sensor is activated to collect the pedal's vibration frequency f and vibration intensity K.

[0085] Determine if adjustment is needed:

[0086] Find the permissible vibration intensity K corresponding to the current vibration frequency f in the frequency-intensity table. i The measured vibration intensity K and K i When comparing, when K > K i The target installation mode is set according to the current vibration frequency f, and the adjustment direction and adjustment stroke of the auxiliary support point of the IBC drive motor are determined according to the current vibration frequency f.

[0087] In some embodiments of the present invention, if the K collected within 30 consecutive seconds is greater than K... i If this is detected, it is determined that the IBC installation mode needs to be adjusted. This effectively prevents the device from frequently adjusting the IBC installation mode.

[0088] Determine the adjustment direction and target mode:

[0089] When f≤(2(f) min +f max When f+A Hz is 3, meaning the current IBC installation mode is relatively low, set f+A Hz as the target IBC installation mode.

[0090] When f>(2(f) min +f max When fB Hz is 3, set fB Hz as the IBC installation modal target.

[0091] In some embodiments of the present invention, the value of A ranges from 3 to 5.

[0092] In some embodiments of the present invention, the value of B ranges from 3 to 5.

[0093] Perform adjustment actions:

[0094] Based on the difference between the target mode and the current mode when the IBC is installed, calculate the required rotation angle θ of the stepper motor:

[0095] When it is necessary to improve the mode, control the stepper motor to rotate by an angle θ, which drives the adjustment rod 4 to rotate, so that the slider 2 moves towards the upper end of the IBC drive motor;

[0096] When it is necessary to reduce the mode, the stepper motor is reversed by θ angle, which drives the adjusting rod 4 to rotate, so that the slider 2 moves to the lower end of the IBC drive motor.

[0097] like Figure 3 and Figure 4 As shown, slider 2 is close to the upper end of the IBC drive motor body, and elastic block 3 has a small local contact area with the motor cylinder. With slider 2 closer to the upper end of the IBC drive motor, the contact area between elastic block 3 and the outer cylindrical surface of the motor decreases, and the normal support force of slider 2 on the motor cylindrical surface also decreases. The automatic adjustment device forms a hinge point support constraint on the IBC assembly, allowing the IBC assembly to rotate slightly around the contact area of ​​elastic block 3. Under this installation method, its natural frequency upper limit is...

[0098]

[0099] Compared with the installation method in the prior art, the present invention can achieve a natural frequency variation of 0 to 4.3 times, which is equivalent to shortening the cantilever L to L / 2.

[0100] like Figure 5 and Figure 6As shown, slider 2 is close to the end of the IBC drive motor body, and elastic block 3 has a large contact area with the motor cylinder. Elastic block 3 is compressed, generating a large support reaction force on the IBC assembly, forming a fixed rigid constraint similar to the IBC mounting surface. Under this mounting method, its upper limit of natural frequency is...

[0101]

[0102] Compared to existing installation methods, the inherent frequency is increased by 6.3 times, which is equivalent to shortening the cantilever L to 2L / 5.

[0103] Verify the adjustment effect

[0104] After completing the adjustment, the vibration intensity K' of the pedal is collected again. If K' ≤ K i If K'>K, then the adjustment is confirmed to be successful; i If the condition is met, return to the step of determining the adjustment direction and target mode, and re-execute the adjustment.

[0105] Locking support position

[0106] After successful adjustment, the stepper motor is locked, pinning the U-shaped slider position. When a pedal release signal is detected, all vibration data acquisition is reset. When a vehicle engine shutdown signal is detected, the U-shaped slider is moved to its uppermost position.

[0107] By adding this auxiliary support device, the IBC assembly installation mode can be dynamically adjusted within the range of 0 to 6.3 times by adjusting the position of the IBC support, and the adjustment method is simple and reliable.

[0108] This invention discloses an automatic adjustment method and device for the installation mode of an integrated brake controller (IBC) in a vehicle state. By adding an auxiliary adjustable IBC support device while maintaining the original installation method of the IBC assembly, the overall vehicle installation mode of the IBC is improved, avoiding resonance with excitation sources such as the engine, road surface, and transmission system. This auxiliary support bracket has a simple structure, is easy to operate, and has a wide adjustable range of installation modes, making it widely applicable to different vehicle models and different IBC assemblies. This invention pioneers a method and control device for automatic adjustment of the IBC installation mode in a vehicle state, which can completely and actively avoid vehicle vibration problems caused by IBC installation mode resonance in new energy vehicles. It is highly feasible, structurally simple, highly reliable, and low-cost, possessing the potential for the exploration and application of new technologies in active control of current new energy vehicles.

[0109] It will be readily understood by those skilled in the art that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, combinations, substitutions, improvements, etc., made under the spirit and principles of the present invention are included within the protection scope of the present invention.
