Full-Size SUV Electric Steps (GLS)

-- Steady & Reliable Manufacturer --

Technical Overview

Electric steps for full-size SUVs (such as the Mercedes-Benz GLS) are engineered for maximum length, structural rigidity, and synchronized operation. Due to the vehicle's long wheelbase and substantial weight, these systems frequently incorporate a Dual-Motor Actuation System on each side, ensuring that the step deploys evenly and without deflection across its entire span. The step platform is typically wider to accommodate the vehicle’s larger door aperture and higher step-up height.

The ECU manages the synchronization of the two motors and utilizes Redundant Load Monitoring to provide a robust anti-pinch function across the extended platform, meeting the safety requirements for full-size luxury vehicles.

Introduction

The largest SUV platforms, exemplified by the Mercedes-Benz GLS, require an access solution that matches their substantial scale. Our full-size electric steps provide a stable, wide, and fully automated platform, making cabin and roof access safe and effortless. The engineering focus is on achieving stability and reliability across the longest possible span.

Bohai Automotive Technology Co., Ltd. addresses the challenges of this segment by reinforcing all load-bearing components and developing advanced electronic synchronization protocols. Our commitment ensures that this necessary accessory operates with the precision expected on a full-size luxury vehicle.

Applications

Mercedes-Benz GLS (All Models): Essential for facilitating safe entry into the high-riding, large cabin and accessing the roof luggage area.
Other Large SUV Platforms: Applied to similar large vehicles that require a long, high-capacity step (e.g., Cadillac Escalade, Lincoln Navigator equivalents).
High-Capacity Passenger Use: Ideal for families or chauffeur services where multiple large adults frequently use the steps.
Global Export to Large Vehicle Markets: Targeting North American and Middle Eastern markets where large SUV sales volumes are high.

Common Questions

Q: Does the dual-motor system require a separate battery source?
A: No. The system operates efficiently on the vehicle's standard 12V system. The ECU manages the current draw to ensure the combined load is within the safe parameters of the vehicle's electrical capacity.

Q: How is the risk of corrosion managed across the long linkage arms?
A: All extended linkage components undergo a thorough E-coating process followed by a powder coat, ensuring complete, comprehensive protection against corrosion, especially in areas prone to road splash.

Q: What is the weight addition of the full-size dual-motor system?
A: While heavier than single-motor steps, the use of optimized steel and aluminum components minimizes the weight penalty. The total weight addition is carefully calculated to have negligible impact on the vehicle's performance or payload capacity.

Core Features

Even Load Distribution: The dual-motor system ensures the step deploys evenly, eliminating twisting and maintaining stability across the long platform length.
High Structural Capacity: Reinforced linkage and wider mounting plates provide the necessary strength to support the heaviest vehicles and passengers.
Synchronized Operation: Advanced control logic guarantees both motors deploy and retract at identical speeds, crucial for the smooth operation of the long step.
Wider Stepping Surface: The increased platform width provides a more comfortable and secure footing for the high step-in height of the full-size SUV.

Manufacturing & Customization

Manufacturing involves specialized, Extra-Long Welding Jigs to ensure the dimensional accuracy of the mounting brackets for the longest wheelbases. The dual-motor synchronization is calibrated and tested using Digital Oscilloscopes on the production line.

Customization Opportunities: Focused on large-scale logistics and premium fit:

Extended Step-Down: Offering brackets that provide an additional few centimeters of drop to optimize the step height for the tallest SUVs.
Long-Term Service Kits: Providing pre-packaged maintenance and replacement parts kits tailored for fleet or commercial operators.
Load Certification: Conducting and documenting specific load certifications to meet the requirements of particular full-size vehicle conversion companies.

Material Selection

Heavy-Gauge Q345B Steel is essential for the extended structural arms to maintain rigidity over the long span. This steel is heat-treated for enhanced fatigue resistance.

The longest step platforms utilize Thick-Walled Extruded 6061 Aluminum with internal webbing, designed to prevent vertical flex across the length.

Custom-Molded Polymer End Caps are used to provide a streamlined, integrated look at the ends of the long platform, matching the vehicle's body styling.
