ZF, a global leader in automotive technology, has strengthened its position as a top supplier of chassis components through a major agreement with a leading manufacturer. This deal underscores the significance of the company’s new Chassis Solutions Division, which enables Software-Defined Vehicles through innovative “by-wire” electronic brake control systems. As a one-stop provider for all chassis components, ZF has secured a high-volume production agreement for next-generation steering and by-wire electronic brake control technology in a single vehicle segment.
The project integrates Electro-Mechanical Braking (EMB) technology on the rear axle, along with ZF’s advanced Integrated Brake Control (IBC) and conventional front calipers. This hybrid brake system, combining by-wire and hydraulic components, offers greater flexibility to manufacturers. Additionally, the agreement includes ZF’s Electric Rotary Ball Steering Gear, a cutting-edge steering technology. By integrating traditional braking with innovative steering solutions, ZF is further solidifying its leadership in delivering comprehensive chassis solutions to the automotive industry.
ZF Board Member and Head of the Chassis Solutions Division, Peter Holdmann, expressed pride in the company’s advancements, stating:
“ZF’s leadership in chassis technology continues to provide tangible value for our customers. By consolidating our expertise in steering, braking, dampers, actuators, and related software into a single division, we aim to offer the most extensive range of Chassis Solutions products and systems worldwide.”
Holdmann further emphasized that this consolidated expertise enables the development of cutting-edge solutions that integrate advanced engineering, innovative design, and state-of-the-art technologies for optimal performance and safety.
ZF’s Electro-Mechanical Braking (EMB) technology plays a crucial role in advancing software-defined vehicles. By eliminating traditional hydraulic brake fluid, this dry braking system enhances both safety and driving comfort. The integration of by-wire electronic brake control unlocks new functionalities, such as autonomous emergency braking and steering adjustments during collision scenarios.
“This major agreement validates our strategic direction and success,” Holdmann remarked. “With a comprehensive portfolio of hardware and software solutions for vertical, lateral, and longitudinal vehicle dynamics, we provide customers with a single-source system, actively shaping the transition to software-defined vehicles.”
ZF’s Electro-Mechanical Braking (EMB) system eliminates the need for brake fluid by generating brake pressure through electric motors instead of traditional hydraulics. Brake signals are transmitted electronically from the pedal to the motor, leading to the term “dry electronic brake control.”
The EMB system seamlessly integrates with ZF’s Integrated Brake Control (IBC), a fully integrated electro-hydraulic system designed for superior braking performance. It supports features like fully automated emergency braking, energy recuperation, and redundant backup options, making it ideal for passenger and light commercial vehicles, including those with automated driving capabilities.
The hybrid brake system consists of an electric braking system on the rear axle and a hydraulic system on the front axle, compatible with ZF’s widely used Colette-type calipers. Available in single- and twin-piston designs, this setup ensures cost efficiency, reduced CO2 emissions, and high performance across all powertrain types, including electric and hybrid vehicles.
ZF’s Electric Rotary Ball Steering Gear (RCB EPS) is a 48V electric-powered unit designed to replace conventional hydraulic systems. Supporting ADAS features up to Level 2/2+, this system enhances steering response and performance while being adaptable for higher levels of automated driving. Additionally, the integrated design reduces vehicle assembly costs and helps lower CO2 emissions.
With over 50 years of experience in brake system development and production, ZF has manufactured more than three billion brake components, making it one of the world’s largest suppliers.
Following the merger of its Active Safety Technology and Passenger Car Chassis Technology divisions in January 2024, ZF now offers the industry’s most comprehensive portfolio of fully electronically controlled steering, braking, and damping systems for software-driven vehicles. This strategic move positions ZF as a powerhouse in modern chassis systems, driving innovation and industrialization in the automotive sector.
