Title: Limited Slip Differential for automobile using break system and method for controling the same
Inventor: BAE IN GYU
IPC: F16H48/30
Filed: 2000-12-26
Abstract: PURPOSE: A limited slip differential by using a brake system and controlling method therefor are provided to limit differential by simplifying structure and to reduce a producing cost. CONSTITUTION: A main supplying line(L) transfers hydraulic pressure by being connected to a master cylinder(M) generating brake pressure. The hydraulic pressure is transferred into driving wheels(F1,F2,R1,R2). A hydraulic controlling unit(C) is installed on the main supplying line to selectively isolate the hydraulic pressure. Plural hydraulic supplying lines(L1,L2,L3,L4) supplies the hydraulic pressure into a brake assembly of the driving wheels. The hydraulic pressure generated in the master cylinder of the brake system is divided into the plural hydraulic pressure supplying lines. The hydraulic pressure is applied to the brake assembly of the driving wheels by passing through the plural hydraulic pressure supplying lines. Thereby, a limited slip differential by using the brake system controls the limited slip differential by simplifying structure to reduce a producing cost.

Title: Active front steering system of cars
Inventor: DOO MIN SU
IPC: B62D6/04
Filed: 2000-12-27
Abstract: PURPOSE: An active steering system of a vehicle is provided to improve the safety of a vehicle by removing an unnecessary yaw-moment element and to reduce the unit cost by directly measuring and calculating the side angle of a vehicle. CONSTITUTION: An active steering system of a vehicle comprises a steering angle detecting unit(10), a yaw detecting unit(12), an ECU(Electronic Control Unit)(14), and an EPS(Electronic Power Steering) system(16). The steering angle detecting unit detects a steering angle and applies the steering angle to the ECU. The yaw detecting unit detects the yaw of a vehicle and applies the yaw to the ECU. The ECU increases and decreases the steering angle by comparing the steering angle to the yaw. The EPS system controls the steering of the vehicle depending on the variable steering angle. The side force of a tire is calculated by using the tack force of a motor. If an excessive yaw occurs, counter steering is performed for the minimum time.
