Munich Motor Show 2023, Germany: ZF’s drive-by-wire technology is launched on the market

At the 2023 German International Automobile and Smart Mobility Expo (IAA Mobility 2023) in Munich, Germany, the global technology company ZF Group will focus on displaying wire-controlled technology products. ZF has the most comprehensive portfolio of purely electronic steering, braking or suspension systems for software-defined automotive products. With drive-by-wire technology, the chassis system no longer requires mechanical connections or oil systems. At the same time, pure electric ultra-compact and lightweight 800-volt drive systems will also become the future direction, with the world's leading torque density.

Dr. Peter Holdmann, head of ZF's Chassis Technology Division, said: "ZF's drive-by-wire system opens a new era of vehicle control. Intelligent intelligent control for longitudinal, lateral and vertical dynamics The connected chassis system can improve driving dynamics, and our actuators and product functions can meet the vehicle motion control in three directions, which has unique advantages. "Pure electronic control and intelligent connected wire control systems can provide better vehicles. Control, shorter braking distance, while making the vehicle more flexible in steering, more stable in high-speed driving, and with higher cruising range and efficiency.

As an industry-leading developer and manufacturer, ZF’s control-by-wire systems do not require mechanical connections:

● Steer-by-wire (including rear-wheel steering)

● Brake-by-wire with integrated brake control

●Electronically controlled active damping

The integration of these technologies forms an intelligent network-connected chassis system that can be coordinated with the cubiX software as a whole.

Compact, lightweight 800-volt drive system

ZF has launched the future-oriented 800-volt electric drive system EVSys800 at the end of June to warm up for the Munich Auto Show. EVSys800 is a modular 800-volt drive system consisting of silicon carbide power electronics, motors and reducers. While the design of the ZF EVbeat concept car is extremely compact and lightweight, its performance is not inferior: the maximum torque of the rear axle is 5200 Nm, which is converted into a torque density of 70 Nm/kg, which is extremely high for a passenger car. of. The continuous output power of the car's electric motor is about 75% of the peak power, reaching 206 kilowatts and 275 kilowatts respectively.

In terms of size, thanks to the compact reducer and the patented "braided winding" technology of ZF electric motors, the width of this drive system is reduced by 50 mm, allowing coaxial installation on the drive axle, saving space.

With a total weight of 74 kilograms, the EVSys800 has the same power output as current ZF production 800-volt series drive systems, but is approximately 40 kilograms or 30% lighter.
