"Three-step" strategy, deploying intelligent chassis across the entire domain

In recent years, the rapid development of intelligence and electrification has greatly subverted traditional car control modes and driving experience, while also giving new development opportunities to intelligent chassis.

Compared with traditional car chassis, the advantages of smart chassis are obvious: since a large number of mechanical connection devices and auxiliary devices such as pneumatic and hydraulic pressure have been eliminated, they are replaced by more accurate and sensitive sensors, control units and electromagnetic actuators, which not only respond to The speed and control accuracy are significantly improved, and energy consumption can be greatly reduced. Because of this, the intelligence of the chassis is generally considered to be the only way to achieve a high degree of electrification and intelligence.

In the past period of time, the rapid popularity of new energy vehicles and various intelligent driving assistance functions in the terminal market has been inseparable from the assistance of intelligent chassis. For example, functions such as ACC, AEB, TJP, and HWP that are highly related to ADAS require online control. Implemented on a dynamic basis. With the development of higher-level autonomous driving, new demands for intelligent chassis are gradually emerging.

"The chassis, as the core of vehicle dynamics control, is showing many new characteristics and needs with the in-depth development of electrification and intelligence, mainly including five dimensions: First, the electronic and electrical architecture is changing from traditional distributed to centralized evolution, and is even expected to further evolve towards cloud services in the future; second, the cross-domain integration of multiple actuators, such as the integration of braking, steering and suspension; third, as the functions and application scenarios on smart cars become more and more Complex, the requirements for the speed of software iteration are getting higher and higher. OEMs pay more attention to safety and comfort, requiring hardware modularization, hardware design embedded and expandable, and software portable and upgradeable; fourth, functions must be fully considered Safety and information security; fifthly, in terms of comfort, the driver’s driving experience and driving pleasure need to be considered.” Talking about the understanding of the current trend of intelligent chassis, Su Qianting, co-founder of Likry Technology, said.

Likrypton’s “three-step” strategy for smart chassis is a forward-looking layout based on the prediction of the above trends:

In the 1.0 stage of Likrypton Intelligent Chassis, the focus is on the longitudinal and vertical control of the vehicle, namely brake-by-wire and suspension-by-wire, and the realization of coordinated control of the vehicle's longitudinal and vertical directions to help the wider popularization and application of advanced assisted driving.

Likrypton Intelligent Chassis 2.0 stage: In addition to the existing longitudinal and vertical layout, it adds lateral control of the vehicle, that is, steer-by-wire, and realizes three-in-one control of longitudinal, lateral, and vertical directions to support fully automatic driving.

LiKr Intelligent Chassis 3.0 stage: Aiming at a new generation of electronic and electrical architecture, combined with the development platforms of mainstream car companies, to create an integrated intelligent chassis with active control, self-adaptation and self-learning capabilities.

Since its establishment in 2021, LIKE has been well-known in the industry for its leading brake-by-wire technology. It is the world's first mass production of the Two-box brake-by-wire system DHB-LK® based on a fully hydraulic decoupling solution, and is the first in the industry to achieve integration. The mass production of the One-box brake-by-wire system IHB-LK®, a type of intelligent braking system, has become the only scientific and technological company in China to realize the fully hydraulic decoupling brake-by-wire dual-line product layout and large-scale mass production.

The release of the new product strategy means that Likrypton has officially launched an attack on the core technology of global intelligent chassis.

At present, the industry generally believes that to create a truly intelligent, comfortable and safe driving experience, in addition to brake-by-wire, it is also inseparable from precise control of the vertical and lateral movement of the vehicle. Especially for autonomous driving at L3 level and above, steer-by-wire realizes complete decoupling between the steering wheel and the steering system, allowing for higher steering accuracy and flexible layout of the cabin space. It is generally considered to be a high-end autonomous vehicle. A must for driving.

Thanks to the rapid development of core technologies such as sensors, chips and algorithms, many global mainstream car companies have planned to launch models with L3 or L3+ level autonomous driving functions in the next 1-2 years. In China, many car companies are also secretly working hard to continuously improve the existing L2 and L2+ level intelligent driving experience, so as to move closer to L3+ or even higher-level autonomous driving. From this point of view, it is just the right time for Likrypton to enter smart suspension and wire-controlled steering.

It is worth noting that although a group of outstanding players have gathered in the field of intelligent chassis, and other companies choose one of the subdivided tracks to continue to deepen their cultivation, companies like Likrypton that truly have full range of intelligent chassis research and development capabilities and product matrix are not the same. not much. We are confident that in the future, with the smooth advancement of Likrypton’s new product strategy, it will surely lead the intelligent chassis to achieve greater breakthroughs.

Exhibiting hard power and performing the “acceleration” of profit

Along with the release of the new strategy, Li Krypton also introduced in detail the development goals and core product layout at each stage at this auto show.

"Among them, the intelligent chassis 1.0 phase, Li Krypton plans to complete the layout this year. In 2022, we have already mass-produced Two-box's DHB-LK® and One-box's IHB-LK® in terms of longitudinal control, and are now stepping up research and development. The first is the air suspension control system ECAS-LK, which is expected to be put into mass production next year." Talking about the current layout progress, Su Qiantang said. By then, Likrypton will complete the control of the vehicle's X-axis and Z-axis in two dimensions, as well as deep collaboration in the longitudinal and vertical directions.

At this auto show, Likrypton also showed the public a full range of products in the 1.0 phase of intelligent chassis. Among them, DHB-LK®, as the first mass-produced hydraulic decoupling brake-by-wire system, realizes pedal decoupling of the brake-by-wire function and can be matched with any brand of basic ESC or ABS products, greatly reducing the development time of the OEM. time and R&D investment while fully meeting the stringent braking redundancy requirements of L3 and above autonomous driving.

Not only that, DHB-LK® can support energy recovery of up to 0.3g, which can effectively increase the cruising range of new energy vehicles by 16-20%, and due to the complete decoupling between the brake pedal and the hydraulic mechanism, there is no pedal idle time. stroke, DHB-LK® effectively avoids pedal sinking when actively building pressure, achieving a more delicate and reliable pedal feel and supporting different driving styles.

By further integrating DHB-LK® with the body stability control system, Likrypton has also developed a more integrated One-box brake-by-wire system IHB-LK®.

According to Su Qiantang, for the IHB-LK® system, Li Krypton has launched three different versions, namely standard version, flagship version and lightweight version:

The standard version integrates DHB-LK®, ESC and dual-channel EPB control, which can achieve high dynamic response within 150ms;
