Development of the Central Coordinated Motion Control System for Pure Electric Vehicles

The IM L6 is the fourth product under the IM brand, featuring both rear-motor two-wheel drive and dual-motor all-wheel drive configurations. This article introduces the Ling Xi Digital Intelligent Chassis system of the IM L6, which includes air springs, CDC (Continuous Damping Control), rear-wheel steering system, braking system, front-wheel steering system, and electric drive system. The study explores how adjusting the damping of the CDC achieves a more comfortable damping effect. Through precise control of the rear-wheel steering system, the vehicle achieves smaller turning radii, crab walk capability, optimized response in moose test conditions, and improved performance on split-friction surfaces. By coordinating the IBS (Intelligent Brake System) and VMC (Vehicle Motion Control), an exceptionally comfortable braking experience is achieved.
