As the automotive industry rapidly transitions toward electrification, intelligent driving and steer-by-wire technologies, OEMs are placing increasingly higher demands on Electric Power Steering (EPS) systems. Compact packaging, higher functional safety levels, intelligent integration capability and software-defined steering functions are becoming critical requirements for next-generation vehicle platforms.

To address these evolving market needs, XEPS proudly announces the launch of its self-developed Brushless PPK (Power Pack) platform — an integrated steering power solution designed for both C-EPS and P-EPS applications.

The new XEPS PPK platform combines the brushless motor, ECU controller, power electronics and safety communication modules into a single compact assembly, delivering improved integration efficiency, enhanced reliability and future-ready intelligent steering capabilities.

What is a PPK (Power Pack)?

The PPK (Power Pack) is the core power unit of an Electric Power Steering system. It integrates multiple critical components into one highly compact module, including:

• Brushless DC Motor (BLDC Motor)
• ECU Controller (Electronic Control Unit)
• Power Driver Module
• Functional Safety Module
• Communication & Cybersecurity Architecture

Unlike conventional EPS systems that require a separate external controller, the XEPS Brushless PPK adopts a fully integrated motor-controller architecture, eliminating the need for an additional ECU installation space and significantly simplifying vehicle integration. This integrated design helps OEMs optimize vehicle packaging, reduce system complexity and improve overall steering system efficiency.

Key Advantages of the XEPS Brushless PPK Platform

1. Integrated Motor and Controller Design

Traditional EPS architectures typically require:

• External ECU controller
• Additional wiring harnesses
• Extra installation brackets and packaging space
• More connectors and communication interfaces

The XEPS Brushless PPK platform integrates all major components into one compact unit, offering:

• Integrated motor and controller architecture
• No separate ECU required
• Reduced wiring harness complexity
• Lower connector count
• Simplified vehicle assembly
• Improved packaging flexibility
• Reduced overall system weight

This highly integrated solution is especially suitable for:

• Electric passenger vehicles
• A/B-segment vehicle platforms
• Electric three-wheelers
• Lightweight commercial vehicles
• Compact EV platforms with limited installation space

By minimizing external components and reducing packaging requirements, the XEPS PPK helps OEMs save valuable vehicle space while supporting lightweight vehicle development.

2. Improved Reliability and Durability

The integrated architecture of the XEPS PPK significantly improves system robustness compared with traditional separated motor-controller solutions.

Key reliability advantages include:

• Reduced EMC/EMI interference risk
• Lower connector failure probability
• Enhanced vibration resistance
• Improved waterproof and dustproof performance
• Better thermal management efficiency
• Higher long-term durability

By eliminating long harness connections between the motor and external ECU, the system can maintain more stable communication and power transmission under harsh vehicle operating conditions. This makes the XEPS PPK particularly suitable for demanding automotive environments and long-life vehicle applications.

3. ASIL D Functional Safety Support

Safety remains one of the most critical requirements in modern steering systems. The XEPS Brushless PPK platform is developed in accordance with ISO 26262 functional safety processes and supports up to ASIL D functional safety requirements.

To meet different customer platform strategies, XEPS provides multiple redundancy architectures, including:

• Non-redundant
• Semi-redundant
• Fully redundant

The platform is designed to support advanced ADAS and future autonomous driving steering applications requiring high system safety integrity.

4. Ready for Intelligent Driving Applications

As vehicles become increasingly software-defined and intelligent, steering systems are evolving beyond basic assist functions.

The XEPS PPK platform supports advanced intelligent steering features, including:

• Multiple Assist Modes
• OTA (Over-the-Air) Software Updates
• LKA (Lane Keeping Assist)
• APA (Automatic Parking Assist)

The platform also reserves sufficient interface capability for future intelligent chassis and steer-by-wire development trends.

5. Cybersecurity Supported

With the rapid evolution of automotive E/E architecture and connected vehicles, cybersecurity protection has become essential for modern EPS systems.

The XEPS Brushless PPK platform supports:

• Secure communication mechanisms
• Software protection strategies
• OTA cybersecurity architecture
• Anti-intrusion system protection

helping OEM customers comply with future intelligent vehicle cybersecurity requirements.
