Dublin, November 4, 2022 /PRNewswire/ — 2022 China Passenger Car Chassis Domain Controller Industry Report added of ResearchAndMarkets.com Recruitment.
The chassis domain consists of transmission, drive, steering and braking systems. Conventional vehicle chassis are ill-suited for vehicle intelligence and autonomous driving development and require chassis-by-chassis transformation. Automotive chassis tend to be electronic, modular and intelligent.
Mechanical decoupling is a prerequisite for chassis technology upgrades. However, in a conventional chassis, braking and steering are mechanically coupled, powered by mechanical forces from the driver controlling terminals with hydraulically amplified force. But in the process of intelligent evolution, the key to chassis electronics is to decouple the mechanical force and replace it with the motor he drives. This improves the accuracy of control and enables a better combination of humans and systems.
In addition to mechanical decoupling, the chassis also requires software and hardware decoupling. Conventional electronic chassis systems are divided into components such as electronic stability control (ESC), electric power steering (EPS), and electronically controlled suspension. Each subsystem is from a different supplier or different development department of his OEM and has independent vehicle power control system and vehicle dynamic control model.
In the development of the chassis controller, problems such as the strong coupling relationship between software and hardware, repeated research and development and high development costs, and the inability to offset adverse effects between subsystems to achieve optimal vehicle control have arisen. increase.
Intelligent Chassis Domain Controllers have emerged to meet the current need for new vehicle technology and new features. In the field of highly automated driving, a chassis that allows centralized control of steering, braking, suspension and even power systems, separation of software and hardware, and coordinated lateral, longitudinal and vertical control The need for domain controller products is growing. Better provide intelligent driving.
There are two development routes for chassis domain controller technology: the full-stack self-development route by select OEMs and the open ecosystem route represented by Tier 1 suppliers.
The Volkswagen MEB platform uses three controllers to control the entire vehicle and activate functions. The ICAS1 vehicle control domain controller combines many functions such as body control management, drive system management, drive system management, power system management, comfort system management, etc., and integrates body, power and chassis domains into one domain controller.
In 2022, NIO introduced the Intelligent Chassis Controller (ICC) with the launch of the ET7. ICC allows chassis design and tuning in all aspects of comfort, handling and drivability, and integrates control functions such as “redundant parking, air suspension and shock absorbers”. The controller also supports high-level autonomous driving scenarios with cross-domain integration. FOTA updates enable flexible and rapid iteration. NIO’s controllers can uniformly adjust and control functions such as air spring leveling, shock absorber damping, and electronic parking brakes.
Regarding the open ecosystem route, chassis domain controllers have high technical barriers and few mass-produced solutions. Tier 1 suppliers are currently working on single/multiple subsystem development (domain) controllers for chassis subsystems. For example, Keboda Technology is shipping a batch of DCC (Dynamic Chassis Control) supporting Xpeng Motors.
This controller is designed to allow dynamic control of the suspension. His two mainstream products from Suzhou Gates Electronics, namely continuous damping dynamic suspension electric control system and air suspension electric control system, are also used for suspension control.
When it comes to integrated control of chassis systems, Chinese suppliers have to learn from world-renowned Tier 1 suppliers.
A brake-by-wire system, ZF’s Integrated Brake Control (IBC) combines Active Kinematics Control (AKC) and an active damping system (sMotion) for brake-by-wire active rear axle steering to provide longitudinal, lateral and vertical Achieve directional safety and security. Comfortable experience. Recently, the most important component of a vehicle steering system, ZF’s front axle steering, also enabled the drive-by-wire separation of software and hardware. All actuation systems are uniformly controlled by the cubiX platform. cubiX is an integrated software suite for vehicle motion control, coordinating all the aforementioned actuators and sensors related to vehicle motion.
ZF’s VMC cubiX collects sensor information from the entire vehicle and the environment to prepare the chassis, steering, braking and propulsion active systems for optimal control. On the other hand, following a vendor-agnostic approach, cubiX can support both ZF and 3rd party components.
Change is the only constant in the turmoil of the intelligent vehicle industry. Full-stack independent development or open ecosystem routes have their own market space. There is still a big gap between China’s chassis (domain controller) Tier 1 suppliers and foreign suppliers.
Fortunately, chassis intelligence is linked to vehicle electrification. His OEMs in China are at the forefront of electrification, offering great opportunities for these Chinese players and bringing back to domestic firms the talent serving Tier 1 suppliers abroad. .
