Automatic Power Side Steps

-- Steady & Reliable Manufacturer --

Technical Overview

Automatic Power Side Steps are based on a sophisticated electromechanical system designed to operate autonomously upon the vehicle’s entry and exit command. The mechanism is centered around a robust, sealed motor unit that drives a complex parallelogram linkage. This linkage ensures the step deploys parallel to the ground, maintaining a consistent and safe stepping height regardless of the deployment angle.

The control module includes a self-diagnosis function and integrates multiple position sensors to monitor the precise location of the step at all times. This dual-redundancy sensing system is vital for safety, particularly when retracting the step back into its stowed position, preventing accidental deployment while driving or during automated car washes. The core structural components are designed for a 15-year operational life cycle under typical use conditions.

Introduction

The shift from static to automatic running boards marks an evolutionary leap in vehicle convenience. These systems offer immediate, safe access when needed, and revert to a completely discreet profile when the doors close, preserving the vehicle’s stock aesthetics and maximizing ground clearance. This capability is paramount for premium SUV owners who value both utility and design purity.

Bohai Auto Tech applies its specialized R&D focus to enhance the reliability of the system's electromechanical components. Located on the southern bank of Taihu Lake, our manufacturing advantage stems from a deep commitment to integrating proprietary control software with high-precision fabrication, ensuring that our automatic side steps function flawlessly in diverse global environments.

Applications

Large & Medium SUVs: Ideal for models like the VW Touron (Teramont), Mercedes-Benz GLS, and Volvo XC60 where the stock ride height necessitates a robust, automated step.
Corporate and Commercial Fleets: Applied to high-end MPVs (e.g., Mercedes-Benz V260/Vito) to facilitate easy, professional client access.
Aftermarket Vehicle Enhancement: Used by dealers and distributors globally as a sought-after upgrade that demonstrably improves the vehicle's utility and perceived value.
Extreme Climate Areas: Engineered to perform reliably in areas subject to heavy snowfall, ice, or excessive heat, due to sealed mechanical components.

Common Questions

Q: Can the steps be manually overridden or locked in position?
A: Yes, the control system typically includes a software-based manual override mode, often controlled via a small switch, allowing the steps to be locked in the deployed or stowed position for maintenance or specific off-road conditions.

Q: What is the typical installation time required for the product?
A: Due to the precision fit and "Plug and Play" wire harnesses, a professional installation by a certified technician typically takes between 2 to 4 hours, depending on the specific vehicle model and complexity of the wiring integration.

Q: What kind of noise level is produced during deployment?
A: Our systems are engineered with noise reduction in mind, utilizing high-quality dampening materials and precision-machined gears. The typical operating noise level is below 45 dB at one meter, comparable to a quiet home refrigerator.

Core Features

Precision Electromechanics: Utilizes custom-tuned DC motors and gears designed for a high-duty cycle, minimizing wear and ensuring consistent deployment speed.
Weather Sealing: All moving components and the electronic control module are gasketed and sealed to provide optimal protection against road contaminants and moisture intrusion.
Safety Redundancy: Incorporates dual-sensing technology—current monitoring and positional sensors—to prevent operation under stress and ensure correct stowing.
Vehicle Ride Preservation: The fully stowed position minimizes aerodynamic drag and does not interfere with the vehicle's factory off-road approach or departure angles.

Manufacturing & Customization

Our production line follows strict ISO 9001 standards, focusing on repeatable, high-volume manufacturing. Every component, including the motor and the control unit, undergoes rigorous End-of-Line Testing to verify speed, load capacity, and communication protocols before assembly.

Customization Opportunities: Beyond standard OEM requirements, we provide value-added services:

Bespoke Tread Patterns: Developing proprietary, non-slip tread designs for branding exclusivity or enhanced performance in specific climates.
LED Integration: Incorporating optional LED lighting systems within the step mechanism for ground illumination and safety, with custom wiring integration.
System Calibration: Fine-tuning the deployment distance and timing to perfectly suit vehicles with specialized lift kits or modified door jambs.

Material Selection

The choice of structural materials is based on achieving a balance between minimal weight addition and maximum torsional rigidity. High-Strength, Low-Alloy (HSLA) Steel is used for the critical mounting points and the main pivot axles, providing superior resistance to fatigue and stress cracking.

For the step surface, Extruded 6063 Aluminum is preferred, often featuring an integrated ribbed or textured surface to maximize anti-slip properties.

The electrical connectors are specified as Waterproof, Multi-Pin Automotive Connectors (typically Deutsch or similar quality), ensuring robust signal integrity and power transmission under vibration and moisture exposure.
