Gasgoo Awards 2023 applicant:Electronically Controlled Suspension system from KH Automotive Technologies Co., Ltd.

Product: Electronically Controlled Suspension system 

Description

The electronically controlled suspension system of passenger car generally includes air spring, variable damper, height sensor, acceleration sensor, controller, air supply unit assy, reservoir, pipeline and other components. According to the height sensor, body acceleration sensor and vehicle status signal, the controller can adjust the soft and hard suspension and body height under the premise of meeting the safety requirements, so as to improve the ride comfort and operating stability of the vehicle.  The single and dual cavity stiffness of the dual chamber air spring can be adjusted, which can further improve the vehicle comfort and handling.

Unique advantages

KHAT is a technology-based enterprise engaged in the development, production and supply of passenger car Electronically Controlled Suspension System and core components, with the complete capability of the whole process of matching development, test verification, calibration, production and supply of Electronically Controlled Suspension System. The key components that KHAT can provide include: system controller hardware /software, (single/dual chamber) air spring assy, ASU, etc.  KHAT has a comprehensive air suspension development capability from key components to system level, from ride performance to life reliability, including air spring research and model matching the dynamic mechanics performances, mechanical design, a variety of manufacturing processes, air pressure system design, special test equipment development and other knowledge areas. Meanwhile, the air spring compression and assembly line are the core accumulated by KH for many years, in which the implanted core algorithm has certain uniqueness and strong competitiveness.  In terms of electronically controlled suspension systems, KH adheres to positive research and development and has a number of intellectual properties.  The electronically controlled suspension system of KHAT for passenger cars is independently developed using the V Process common in the automotive industry, and can provide a full set of customized solutions from model planning, function definition, matching design, test verification, calibration until SOP.  In the matter of air spring assy and ASU, KH has assembly and some parts of the process development capabilities, and key processes are self-sufficient. The quality of our own assembly products is strictly implemented in accordance with the DV&PV test standards, and we are fully able to deliver qualified products in time according to the needs of customers.

Application

With the development and growth of the domestic new energy vehicle industry and the improvement of model positioning, the characteristics of air suspension based on chassis lifting and high comfort have brought convenience(on/off the car, trunk loading), higher quality(isolate high-frequency vibration, automatic leveling of low-frequency offset deviation with load changes), battery protection(isolate high-frequency vibration, passability), the advantages such as increased mileage(high-speed reduction of chassis/wind resistance) have become an important configuration for OEMs to actively promote. At present, KHAT supplies Air Suspension system and Air Spring assy for L9 and L7 of Li Auto , VOYAH FREE, VOYAH Dreamer, VOYAH and 009ME of ZEEKR. By June 2023, KHAT has completed the delivery of 160,000sets. KHAT obtained about 40 models of 14 OEM’s nominations such as VOYAH, Li Auto, BYD, ZEEKR, LYNK&CO, CHANGAN Auto, AVATR, AION, CHERY and so on.

Prospect
