차량의 능동제어 서스펜션 시스템의 모터구동회로{MOTOR DRIVING CIRCUIT OF ACTIVE GEOMETRY CONTROLLED SUSPENSION SYSTEM}Motor driving circuit of vehicle active control suspension system {MOTOR DRIVING CIRCUIT OF ACTIVE GEOMETRY CONTROLLED SUSPENSION SYSTEM}

본 발명은 차량의 능동제어 서스펜션 시스템의 모터구동회로에 관한 것으로서, 보다 상세하게는 차량의 능동제어 서스펜션 시스템에서 구동되는 2개의 모터에 대해 하나의 H-브리지 회로를 통해 정/역회전을 제어하면서 제어신호의 절환을 위한 릴레이를 통해 2개의 모터를 각각 작동시킴으로써 동일한 모터의 성능을 발휘하면서 제어를 위한 회로소자의 부품수를 감소시킬 수 있도록 한 차량의 능동제어 서스펜션 시스템의 모터구동회로에 관한 것이다. The present invention relates to a motor driving circuit of an active control suspension system of a vehicle, and more particularly, to control forward / reverse rotation through one H-bridge circuit for two motors driven in an active control suspension system of a vehicle. The present invention relates to a motor driving circuit of an active control suspension system of a vehicle capable of reducing the number of components of a circuit element for controlling the same motor by operating two motors individually through a relay for switching control signals. .

AGCS(Active Geometry Controlled Suspension; 능동제어 서스펜션 시스템)은 차속 및 조타각 정보를 수집하여 차량이 기준 속도 이상에서 기준 조타각속도 이상일 때 차량의 뒷바퀴의 이탈이나 미끄러짐을 미리 예측하여 차량의 후륜에 설치된 모터의 작동에 의해 후륜의 토우인 각도를 선회방향 쪽으로 조정하여 차량의 코너링 성능을 극대화시켜주는 시스템으로서, 극한적인 주행상황에서도 이상적인 차량 거동을 만들어 자연스러운 방향전환을 가능토록 하며 차량 뒤쪽의 흔들림을 줄여서 운전자가 안정된 주행을 하게 도와주게 된다. Active Geometry Controlled Suspension (AGCS) collects vehicle speed and steering angle information and predicts the departure or slip of the rear wheels of the vehicle when the vehicle is above the reference speed and above the reference steering angle, so that This system maximizes the cornering performance of the vehicle by adjusting the toe-in angle of the rear wheels by turning to the turning direction.It creates the ideal vehicle behavior even under extreme driving conditions, enabling natural turning and reducing the shaking behind the vehicle to stabilize the driver. It will help you to drive.

이와 같이 후륜의 토우인 각도를 조정하기 위한 모터의 작동은 H-브리지 회로에 의한 다수개의 스위칭회로에 의해 정역회전 작동을 시켜 조정하게 된다. In this way, the operation of the motor for adjusting the toe-in angle of the rear wheel is adjusted by the forward and reverse operation by a plurality of switching circuits by the H-bridge circuit.

도 1은 모터구동회로를 나타낸 회로구성도이다. 1 is a circuit configuration diagram showing a motor driving circuit.

여기에 도시된 바와 같이 모터구동회로는 제 1모터(M1)를 구동하기 위해 H-브리지회로의 스위칭 소자들(FET1, FET2, FET3, FE4)이 외부로부터 인가되는 제어신호에 의해 스위칭 동작하여, 스위칭소자(FET1, FET4)가 스위칭 온되면 A방향으로 배터리전압이 AGCS(Active Geometry Control System)의 제 1모터(10)로 공급되어 제 1모터(M1)가 정회전하도록 되어 있고, 스위칭소자(FET2, FET3)가 스위칭 온되면 B방향으로 배터리전압이 제 1모터(M1)로 공급되어 제 1모터(M1)가 역회전하도록 되어 있다.As shown here, the motor driving circuit switches the switching elements FET1, FET2, FET3, and FE4 of the H-bridge circuit by a control signal applied from the outside to drive the first motor M1. When the switching devices FET1 and FET4 are switched on, the battery voltage is supplied to the first motor 10 of the AGCS (Active Geometry Control System) so that the first motor M1 rotates forward. When the FET2 and FET3 are switched on, the battery voltage is supplied to the first motor M1 in the B direction so that the first motor M1 rotates in reverse.

한편, 제 2모터(M2)를 구동하기 위해 H-브리지회로의 스위칭 소자들(FET5, FET6, FET7, FE8)이 외부로부터 인가되는 제어신호에 의해 스위칭 동작하여, 스위칭소자(FET5, FET8)가 스위칭 온되면 A방향으로 배터리전압이 AGCS(Active Geometry Control System)의 제 2모터(M2)로 공급되어 제 2모터(M2)가 정회전하도록 되어 있고, 스위칭소자(FET6, FET7)가 스위칭 온되면 B방향으로 배터리전압이 제 2모터(M2)로 공급되어 제 2모터(M2)가 역회전하도록 되어 있다.Meanwhile, in order to drive the second motor M2, the switching elements FET5, FET6, FET7, and FE8 of the H-bridge circuit are switched by a control signal applied from the outside, so that the switching elements FET5 and FET8 operate. When the switch is turned on, the battery voltage is supplied to the second motor M2 of the AGCS (Active Geometry Control System) so that the second motor M2 rotates forward. When the switching devices FET6 and FET7 are switched on, The battery voltage is supplied to the second motor M2 in the B direction so that the second motor M2 rotates in reverse.

이렇게 모터구동회로에 의해 마이컴(10)으로부터 8개의 게이트 입력(G1∼G8) 이 각각 스위칭 소자들(FET1∼FET8)에 각각 입력되어 독립적으로 제 1모터(M1)와 제 2모터(M2)의 정회전이나 역회전으로 작동시켜 후륜의 토우인 각도를 조정하게 된다. In this manner, eight gate inputs G1 to G8 are respectively inputted from the microcomputer 10 to the switching elements FET1 to FET8 by the motor driving circuit to independently of the first motor M1 and the second motor M2. By operating in forward or reverse rotation, the toe-in angle of the rear wheel is adjusted.

그러나, 이와 같은 모터구동회로의 경우 2개의 모터를 구동시키기 위해 동일한 구조의 H-브리지회로를 2개 사용하기 때문에 2개의 H-브리지회로를 구성하기 위한 주변소자들이 많이 소요될 뿐만 아니라 부피가 커지며, 회로가 복잡해지는 문제점이 있다. However, in the case of such a motor driving circuit, since two H-bridge circuits of the same structure are used to drive two motors, peripheral devices for constructing two H-bridge circuits are not only large but also bulky. The circuit is complicated.

It is characterized by.

본 발명에서 절환스위치는 복수개의 모터의 각각 양단에 매개되어 공급되는 전류의 경로를 마이컴의 절환신호에 따라 선택적으로 절환하는 제 1내지 제 2릴레이스위치로 이루어진 것을 특징으로 한다.

As shown here, the motor driving circuit is a driving circuit for driving the two first motors M1 and the second motors M2 to change the path of the current supplied according to the switching signals G1 to G4 of the microcomputer. Switch to select one H-bridge circuit for driving the first motor M1 and the second motor M2 in the forward or reverse rotation, and for selecting the first motor M1 and the second motor M2. It consists of a switch 20.

이를 구체적으로 살펴볼 때 스위칭신호(G1∼G4)에 의해 제 1내지 제 4스위치(FET1∼FET4)를 미리 설정된 차례로 스위칭시켜 제 1내지 제 2모터(M1,M2)로 공급되는 전류의 경로를 변경함으로써 제 1내지 제 2모터(M1,M2)를 정회전 또는 역회전시키도록 구성된 H-브리지회로와, H-브리지회로의 스위칭에 의해 공급되는 전류의 경로를 제 1모터(M1)와 제 2모터(M2)로 절환하기 위해 제 1모터(M1)와 제 2모터(M2)의 각각 양단에 매개되어 공급되는 전류를 마이컴(10)의 절환신호(MCU1, MCU2)에 따라 절환하는 제 1내지 제 2릴레이스위치(RY1, RY2)로 이루어진 절환스위치(20)와, H-브리지회로의 제 1내지 제 4스위치(FET1∼FET4)를 스위칭하기 위한 스위칭신호(G1∼G4)와 절환스위치(20)를 작동시키기 위한 절환신호(MCU1, MCU2)를 출력하는 마이컴(10)을 포함하여 이루어진다. In detail, the first to fourth switches FET1 to FET4 are sequentially switched by the switching signals G1 to G4 to change the path of the current supplied to the first to second motors M1 and M2. Thus, the H-bridge circuit configured to rotate the first to second motors M1 and M2 forward or reversely, and the path of the current supplied by the switching of the H-bridge circuit are routed to the first motor M1 and the second motor.
