Abstract

An ESC control system using an ABS actuator for a vehicle is provided to reduce the manufacturing cost through allowing the ABS actuator to control the ESC(Electronic Stability Control) control system. An ESC control system using an ABS actuator(20) for a vehicle comprises an electronic control booster(10) coupled to the ABS actuator and an ECU(30, Electronic Control Unit). The ECU receives various signals, such as signals transmitted from a wheel speed sensor, a transversal G sensor, a yaw-rate sensor, and a steering angle sensor. The ESC control system outputs a booster control signal and an actuator control signal through the ECU. The ESC control system sends the control signal to the electronic control booster so as to generate brake pressure while a driver not stepping on the brake pedal.

본 발명은 ABS 액츄에이터를 이용한 ESC 제어시스템에 관한 것으로, 더 자세하게는 전자제어 부스터를 ABS 액츄에이터에 접속하고, 전자제어유니트를 통해 전 자부스터와 ABS 액츄에이터를 제어하도록 한 것에 관한 것이다.The present invention relates to an ESC control system using an ABS actuator, and more particularly, to an electronic control booster connected to an ABS actuator, and to controlling the electronic booster and the ABS actuator through an electronic control unit.

본 발명이 관계하는 ABS(Anti-lock Brake System)는 자동차가 급제동할 때 바퀴가 잠기는 현상을 방지하기 위해 개발된 특수 브레이크 시스템을 말한다.ABS (Anti-lock Brake System) related to the present invention refers to a special brake system developed to prevent the wheel from locking when the vehicle suddenly brakes.

일반적으로 자동차가 달릴 때는 4개 바퀴에 똑같은 무게가 실리지 않게 되며, 이런 상태에서 급제동을 하면 일부 바퀴에 로크업(lock-up)현상, 즉 바퀴가 잠기는 현상이 발생한다.In general, four wheels do not carry the same weight when the car is running, and sudden braking in this state causes some wheels to lock-up, or lock the wheels.

이는 차량은 여전히 진행하고 있는데도 바퀴는 완전히 멈춰선 상태를 말하는데, 이때 차량이 미끄러지거나 옆으로 밀려 운전자가 차의 방향을 제대로 제어할 수 없게 된다.This means that the vehicle is still in progress, but the wheels are completely stopped, and the vehicle can slide or push to the side, preventing the driver from properly controlling the direction of the car.

이러한 문제를 방지하려면 바퀴가 잠기지 않도록 브레이크를 밟았다 놓았다 하는 펌핑을 해주어야 하며, 이 펌핑 작동을 전자제어장치나 기계적인 장치를 이용하여 1초에 10회 이상 반복되면서 제동이 이루어지도록 한 것이 ABS의 원리이다.To prevent this problem, the brakes should be pumped to prevent the wheels from locking and the pumping operation is repeated 10 times or more per second using an electronic control device or a mechanical device. to be.

ABS는 보통 브레이크와 같은 시스템의 부스터와 마스터실린더에 전자제어장치인 ECU(electronic control unit), 유압조정장치인 HCU(hydraulic control unit), 바퀴의 속도를 감지하는 휠센서(wheel sensors), 브레이크를 밟은 상태를 감지하는 PTS(pedal travel switch)로 이루어진다.ABS is usually used in boosters and master cylinders of systems such as brakes, electronic control units (ECU), hydraulic control units (HCU), wheel sensors that sense the speed of wheels, and brakes. It consists of a PTS (pedal travel switch) that detects the stepped state.

한편 본 발명이 관계하는 ESC(Electronic Stability Control) 제어시스템은 차량이 선회시 한계성능을 넘어가려고 할 때 유압을 이용한 제동력을 발생하여 차량의 거동을 안정화시켜 주는 시스템이다.On the other hand, the ESC (Electronic Stability Control) control system to which the present invention relates is a system that stabilizes the behavior of the vehicle by generating a braking force using hydraulic pressure when the vehicle tries to exceed the limit performance when turning.

도 1에는 본 발명이 관계하는 ABS 액츄에이터의 구성도가 도시되어 있고, 도 2에는 종래의 ESC 액츄에이터의 구성도가 도시되어 있다.1 is a block diagram of an ABS actuator to which the present invention relates, and FIG. 2 is a block diagram of a conventional ESC actuator.

종래에 있어서 상기 ESC 액츄에이터는 ABS 액츄에이터와 별도로 구성되고, 그에 따라 별도의 솔레노이드밸브와 모터를 이용하여 제동유압을 제어하였다.In the related art, the ESC actuator is configured separately from the ABS actuator, thereby controlling the braking hydraulic pressure using a separate solenoid valve and a motor.

도 3에는 도 2의 종래 ESC 액츄에이터에 있어서 차륜 하나에 유압이 작용할 때의 상황을 좀 더 구체적으로 살펴보기 위한 증압 모드 상태도이다.(4개 차륜의 브레이크 제어 유압라인중에서 1차륜에 대한 증압 모드)FIG. 3 is a diagram illustrating a pressure increase mode to more specifically look at a situation when hydraulic pressure is applied to one wheel in the conventional ESC actuator of FIG. 2 (pressure increase mode for one wheel in a brake control hydraulic line of four wheels).

도 3과 같이 종래 ESC 액츄에이터의 경우 제어로직에 의해 증압을 하려면 제1밸브(41'; USV)는 밀폐(Close), 제2밸브(42'; HSV)는 개방(Open), 제3밸브(43'; EV)는 개방(Open), 제4밸브(44'; AV)는 밀폐(Close)시키고, 모터를 구동시켜야 한다.As shown in FIG. 3, in the case of the conventional ESC actuator, to increase the pressure by the control logic, the first valve 41 '(USV) is closed, the second valve 42' (HSV) is open, and the third valve ( 43 '(EV) must be open, and the fourth valve 44' (AV) must be closed, and the motor must be driven.

상기에서 제1밸브(41'; USV)는 운전자가 브레이크를 밟지 않은 상황에서도 차륜에 제동을 걸 경우 개방되어 있으면 압력이 마스터 실린더쪽으로 새어버리기 때문에 브레이크액이 마스터 실린더쪽으로 가지 못하게 막아주는 역할과 최대 제동압력을 조절하는 역할을 한다.Above, the first valve 41 '(USV) serves to prevent the brake fluid from reaching the master cylinder because the pressure leaks to the master cylinder when the driver brakes the wheel even when the driver does not apply the brake. It controls the braking pressure.

이 때 제2밸브(42'; HSV)는 마스터 실린더의 브레이크액을 증압을 위해 사용할 수 있도록 열어 주게 되며, 이 제2밸브(42'; HSV)는 비제어시 닫혀 있다가 제어시 개방(Open)된다.At this time, the second valve 42 '(HSV) opens the master cylinder so that the brake fluid can be used for boosting pressure, and the second valve 42' (HSV) is closed during non-control and then open during control. )do.

이처럼 종래에는 ABS 제어시스템과 ESC 제어시스템이 별도의 액츄에이터를 사용하기 때문에 부품 비용이 증가하게 되어 차량의 원가상승을 유발하게 되는 문제가 있었다.As such, in the related art, since the ABS control system and the ESC control system use separate actuators, component costs increase, thereby causing a cost increase of the vehicle.

본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것이며, 그 목적이 ABS 액츄에이터를 이용하여 ESC 제어시스템을 제어할 수 있도록 하는 것에 의해 원가절감을 도모할 수 있도록 하는 차량의 ABS 액츄에이터를 이용한 ESC 제어시스템을 제공하는 데에 있는 것이다.The present invention has been made in view of the above-described conventional problems, and the object thereof is to control the ESC control system by using an ABS actuator, thereby enabling cost reduction in an ESC using a vehicle ABS actuator.
