Abstract

[목적] 공기 현가 장치의 장점을 살려서 차량의 주행조건 변화에 신속하고 적절하게 대응하여 항상 쾌적한 승차감이 나타나게 하는 전자식 서스펜션 제어장치를 제공함.[Purpose] By utilizing the advantages of the air suspension system, it provides an electronic suspension control device that responds quickly and appropriately to changes in driving conditions of the vehicle so that a comfortable ride is always displayed.

[구성] 차량에 탑재된 전자 제어 장치가 그 입력 단으로 입력되는 차속센서와 조향각 센서, 1쌍의 종가속도 센서, 횡가속도센서, 제동등 출력신호 및 백 라이트 출력신호를 연산 처리하여 소프트 혹은 하드 범위의 어디에 해당되는 가를 판단하여 연산 처리하고, 이를 토대로 출력단을 통해 각 차륜의 솔레노이드 밸브와, 차체 전 후방에 장착된 감쇠력을 액츄에이터를 하드 혹은 소프트로 제어하여 차체의 주행 안정성 및 승차감을 향상시키게 되어 있다.[Configuration] Soft or hard range by calculating and processing the vehicle speed sensor, steering angle sensor, pair of longitudinal acceleration sensor, lateral acceleration sensor, brake light output signal and backlight output signal inputted to the input stage of the vehicle. It is determined to determine where it corresponds to, and based on this, the solenoid valve of each wheel and the damping force installed at the front and rear of the vehicle are controlled by hard or soft actuators to improve the running stability and ride comfort of the vehicle. .

Claims

An electronically controlled suspension device which converts a ride comfort of a vehicle according to driving conditions by calculating and processing an electric signal corresponding to a vehicle speed, a steering angle, etc. input to an electronic control device through various sensors, and inputs the input terminal of the electronic control device. The vehicle speed sensor, steering angle sensor, pair of longitudinal acceleration sensor, lateral acceleration sensor, brake light output signal and backlight output signal are calculated and processed to determine whether the current driving condition falls within the soft or hard range. Based on this, the solenoid valve of each wheel and the damping force actuators mounted on the front and rear of the vehicle are hard or softly controlled through the output stage to improve driving safety and ride comfort of the vehicle body.
