To develop Low-cost system, we used matrix function under the condition of the vehicle having symmetrical brake conduit and four-wheel control capability. As a result, 3 SOL system is a likely candidate for rear-wheel drive vehicles, and a 4 SOL system for front wheel drive vehicles by using a orifices instead of the Normal-Open solenoid.
In developing a logic system, we used the learning control function with a duty pointer containing four hydraulic wave modes.
The actuator weighs 2.2kg and has a volume of 1.2 liters (W90 × H105 × L133)
