What does KDSS mean?

KDSS is a dynamic suspension system developed by Toyota. KDSS is an abbreviation, and its full name is: Kinetic-Dynamic Suspension System, which translates to Electronically Controlled Kinetic Suspension System in Chinese. Extended content about KDSS: 1. Composition: Both front and rear stabilizer bars have independent hydraulic cylinders that control vertical movement and are connected by a hydraulic system. Each stabilizer bar's hydraulic cylinder is divided into upper and lower chambers. The front upper and lower hydraulic chambers are connected to the rear upper and lower hydraulic chambers via their respective hydraulic lines. Each hydraulic line contains an accumulator. KDSS controls a set of valves connected to the accumulators in the hydraulic lines to keep each stabilizer bar in optimal condition. 2. Performance Description: KDSS Normal Mode: When the vehicle is in a turning state, the outer suspensions of both front and rear wheels are compressed, and the inner suspensions are extended. This causes the stabilizer bars to twist, resisting body roll. The two hydraulic lines between the connected hydraulic pumps have no fluid flow, functioning like a conventional suspension but with improved anti-roll capability. In KDSS Off-Road Mode: When one of the four wheels encounters an obstacle and is lifted, the suspension of the lifted wheel is compressed, and the stabilizer bar and hydraulic pump rise together. Fluid flows between the two hydraulic lines connecting the front and rear pumps, absorbing the stabilizer bar's twist. Since the stabilizer bar does not twist, the suspension travel is greater than that of a conventional suspension, and it can adjust according to different road conditions.
