- the brake control system is operated by a separate brake system switch 5.
- the brake system switch 5 is an ON/OFF selection mode switch and allows the entire operation of the brake control system to be automatically controlled according to a command of the ECU 110 in an ON mode. However, in an OFF mode, a brake can be operated in the same manner as the manner of a general vehicle in which the brake control system of the present invention is not employed.
- the brake system switch 5 is installed as a unitary body with a 2 shift key switch 7 for allowing the vehicle to start or is installed on a dashboard.
- the brake system switch 5 may also be connected to an emergency switch that is directly connected to a battery (not shown). In this case, even though a problem occurs in the entire control system of the vehicle, the emergency switch 8 is operated so that only the brake control system can be controlled and more safe car driving can be made.
- the composite control hydraulic unit U includes: a traction valve 30 for controlling the amount and flow of oil forcibly transmitted from the master cylinder 20 to control a brake oil pressure caused by the oil; a low pressure accumulator 40 in which the oil flowed out from the wheel brake 10 is temporarily stored; a Normal Open (NO) solenoid check valve 50 installed between the wheel brake 10 and the traction valve 30 and controlling the amount and flow of the oil transmitted to the wheel brake 10 to control a brake oil pressure applied to the wheel brake 10; a Normal Close (NC) solenoid valve 60 installed between the wheel brake 10 and the low pressure accumulator 40 and controlling the amount and flow of the oil transmitted to the low pressure accumulator 40 from the wheel brake 10 to control a brake oil pressure applied to the wheel brake 10; a pump 70 for ejecting the oil stored in the low pressure accumulator 40; a high pressure accumulator 80 in which the oil ejected from the pump 70 is temporarily stored and which is connected to the traction valve 30; a pressure sensor 85 installed in the high pressure
- the wheel brake 10 includes a wheel disc fixed on a wheel, a pad for generating friction with the wheel disc, a wheel cylinder for closely adhering the pad to the wheel disc, and a wheel speed sensor 6 for sensing the speed of the wheel when the wheel is rotated.
- the wheel brake 10 is a general technology and thus, a further detailed description thereof will be omitted.
- the traction valve 30 includes a check valve 31 and an NC solenoid valve 32.
- the check valve 31 is a one-direction valve that is opened only toward the wheel brake 10 and the high pressure accumulator 80 from the master cylinder 20.
- the NC solenoid valve 32 is closed in a normal state OFF in which power is not applied and is opened in a state ON in which power is applied, thereby opening the master cylinder 20, the wheel brake 10, and the high pressure accumulator 80 in both directions.
- the traction valve 30 includes the check valve 31 and the NC solenoid valve 32 so that the oil ejected from the master cylinder 20 in the normal state OFF in which power is not applied, can flow only into the wheel brake 10 and the high pressure accumulator 80 and therefore, a brake oil pressure is generated in the wheel brake 10 and the NC solenoid valve 32 is opened in the state ON in which power is applied so that the oil can freely flow between the master cylinder 20, the wheel brake 10, and the high pressure accumulator 80 and the brake oil pressure can be generated in both directions.
- the NO solenoid check valve 50 includes a check valve 51 and an NO solenoid valve 52.
- the check valve 51 is a one-direction valve that is opened only toward the traction valve 30 from the wheel brake 10.
- the NO solenoid valve 52 is opened in a normal state OFF in which power is not applied and opens a flow path between the traction valve 30 and the wheel brake 10 in both directions and is closed in a state ON in which power is applied, thereby closing the flow path between traction valve 30 and the wheel brake 10.
- the NO solenoid check valve 50 includes the check valve 51 and the NO solenoid valve 52 so that the oil can freely flow between the traction valve 30 and the wheel brake 10 in the normal state OFF in which power is not applied and the oil pressure can be generated in both directions but in the state ON in which power is applied, the oil can flow only into the traction valve 30 and the brake oil pressure is not generated in the wheel brake 10.
- the NC solenoid valve 60 closes the flow path between the wheel brake 10 and the low pressure accumulator 40 in the normal state OFF in which power is not applied, so that the oil does not flow into the flow path between the wheel brake 10 and the low pressure accumulator 40. In the state ON in which power is applied, the NC solenoid valve 60 opens the flow path between the wheel brake 10 and the low pressure accumulator 40 so that the oil can freely flow in both directions.
- the pump 70 allows the oil stored in the low pressure accumulator 40 to be flowed into the high pressure accumulator 80.
- the high pressure accumulator 80 is a kind of damping chamber, compensates for a volume change of the oil stored according to temperature characteristics and keeps a proper pressure during parking.
- the pressure sensor 85 generates a corresponding pressure signal by the oil pressure caused by the oil stored in the high pressure accumulator 80.
- the pressure signal generated in the pressure sensor 85 is used to operate an ABS mode, a TCS mode or an ESP mode or to determine whether the vehicle is rapidly braked according to speed of the state where the driver steps on the brake pedal and the degree of a pedal effort.
- the shuttle valve 90 includes a check valve 91 and an NC solenoid valve 92.
- the check valve 91 is a one-direction valve that is opened only toward the master cylinder 20 from the low pressure accumulator 40.
- the NC solenoid valve 92 is closed in a normal state OFF in which power is not applied and is opened in a state ON in which power is applied, thereby opening a flow path between the low pressure accumulator 40 and the master cylinder 20 in both directions.
- the shuttle valve 90 includes the check valve 91 and the NC solenoid valve 92 so that the oil of the low pressure accumulator 40 can flow only into the master cylinder 20 and a brake oil pressure is generated only in the mater cylinder 20 in the normal state OFF in which power is not applied, and in the state ON where power is applied, the shuttle valve 90 allows the oil to be freely flowed into the flow path between the low pressure accumulator 40 and the master cylinder 20 so that a bidirectional brake oil pressure is generated.
- the speed sensor 101 generates a speed signal corresponding to acceleration or deceleration of the vehicle when the vehicle is driven.
- the accelerator sensor 102 generates a corresponding acceleration signal when the driver steps on the accelerator.
- the brake sensor 103 generates a corresponding brake signal when the driver steps on the brake pedal 21.
- the gear position sensor 104 generates a corresponding gear transmission signal when the driver shifts the TM gear.
- the ECU 110 controls the composite control hydraulic unit U, more specifically, the traction valve 30, the NO solenoid check valve 50, the NC solenoid valve 60, the pump 70, and the shuttle valve 90 by collectively determining driver s driving will and brake release will.
- the ECU 110 senses whether the vehicle is in a driven/stopped state to automatically control brake maintenance and brake release and to properly change a current mode into an ABS mode, a TCS mode, or an ESP mode.
- the brake control system operates when the brake system switch 5 is in an ON mode, and when the brake system switch 5 is in an OFF mode, the traction valve 30 is turned on when the driver steps on the brake pedal 21 so that the same brake operation as that of a vehicle in which the brake control system of the present invention is not employed can be performed.
- the brake oil pressure applied to the wheel brake 10 is completely recovered to the master cylinder 20, the brake state of the wheel brake 10 is released and the vehicle moves.
- the brake sensor 103 does not generate the brake signal and the ECU 110 determines that the driver has a driving will and cuts off the power (OFF) applied to the traction valve 30.
- the brake sensor 103 When the driver steps on the brake pedal 21 so as to stop during driving, the brake sensor 103 generates a brake signal and the speed sensor 101 generates a speed (deceleration) signal and transmits the speed signal to the ECU 110. Then, the ECU 110 determines that the driver has a brake will through the brake signal and the speed signal and applies power (ON) to the traction valve 30. As such, the brake oil pressure generated in the master cylinder 20 is transmitted to the wheel brake 10 via the traction valve 30 and the NO solenoid check valve 50 and the vehicle stops. When the vehicle stops, the speed signal is not generated in the speed sensor 101 and then, the ECU 110 cuts off the power (OFF) applied to the traction valve 30. Then, the traction valve 30 is closed so that the brake oil pressure applied to the wheel brake 10 is not transmitted to the master cylinder 20 and the wheel brake 10 is kept in the braked state.
- each of the gear position sensor 104 and the accelerator sensor 102 When the driver sets the vehicle into gear and steps on an accelerator pedal so as to restart, each of the gear position sensor 104 and the accelerator sensor 102 generates a gear transmission signal and an acceleration signal and transmits them to the ECU 110. Then, the ECU 110 determines that the driver has a re-driving will through the signals, applies power (ON) to the traction valve 30 and opens a flow path between the master cylinder 20 and the wheel brake 10 in both directions. Then, the brake oil pressure applied to the wheel brake 10 is transmitted to the master cylinder 20 and the brake state is released.
- the speed sensor 101 generates a speed (acceleration) signal and transmits the speed (acceleration) signal to the ECU 110, and the ECU 110 cuts off the power (OFF) applied to the traction valve 30 again.
- the pump 70 pumps oil stored in the master cylinder 20, the low pressure accumulator 40, and the high pressure accumulator 80 strongly and allows the oil to be transmitted to the wheel brake 10 via the shuttle valve 90, the high pressure accumulator 80, and the NO solenoid check valve 50, sequentially, so that a strong brake oil pressure can be applied to the wheel brake 10.
- ABS Anti-Lock Brake System
- the brake sensor 103 and the speed sensor 101 generate a brake signal and a rapid deceleration signal and transmit the signals to the ECU 110.
- the rapid brake state pressure is suddenly applied to the high pressure accumulator 80 and if the pressure exceeds a predetermined value, the pressure sensor 85 generates a pressure signal and transmits the pressure signal to the ECU 110.
- the ECU 110 determines that the driver brakes rapidly through the brake signal, the rapid deceleration signal, and the pressure signal and cuts off the power (OFF) applied to the traction valve 30.
- the brake oil pressure of the master cylinder 20 is transmitted only to the wheel brake 10 in one direction and the brake oil pressure is cut off in an opposite direction. As a result, a strong brake oil pressure may be applied to the wheel brake 10 only by the weak pressure of the brake pedal 21.
- a Traction Control System (TCS) or an Electronic Stability Program (ESP) signal generated when the TCS or ESP operates is transmitted to the ECU 110.
- the ECU 110 applies power (ON) to the shuttle valve 90 and opens the shuttle valve 90 in both directions so that the brake oil pressure can be transmitted in both directions.
- the ECU 110 operates the pump 70.
- the brake oil pressure generated by the master cylinder 20 and the brake oil pressure generated by pumping the pump 70 are transmitted to the wheel brake 10 via the shuttle valve 90, the high pressure accumulator 80, and the NO solenoid check valve 50, sequentially.
- the speed signal generated in the speed sensor 101 and the brake signal generated in the brake signal 103 are transmitted to the ECU 110. Then, the ECU 110 applies power (ON) to the traction valve 30 and opens the traction valve 30 in both directions.
- the brake oil pressure generated in the master cylinder 20 is transmitted to the wheel brake 10 of each wheel via the traction valve 30 and the NO solenoid check valve 50, sequentially, so that the brake operation is performed.
- the driver steps off the brake pedal 21 without the need of brake the oil transmitted to the wheel brake 10 is returned to the master cylinder 20 and pressure is reduced. Subsequently, the ECU 110 cuts off the power (OFF) applied to the traction valve 30 so that the traction valve 30 prevents the oil returned to the master cylinder 20 from being transmitted to the wheel brake 10 again.
- the pressure sensor 85 senses the oil pressure, generates a corresponding pressure signal and transmits the pressure signal to the ECU 110. Then, the ECU 110 applies power (ON) to the traction valve 30 and allows the bidirectional flow of the oil so that the excessive brake oil pressure generated between the traction valve 30 and the wheel brake 10 is transmitted to the master cylinder 20.
- the composite control hydraulic unit for connecting various kinds of sensors 101, 102, 103, 104, and 105, the traction valve, the shuttle valve, the NO solenoid check valve, the NC solenoid valve, and the ECU is employed such that driver s driving and brake will can be correctly reflected and a complete brake operation can be performed during driving or stoppage.
- ABS, TCS, and ESP operations can be completely performed without a driver's additional operation when the driver starts driving after stoppage or when the driver stops during driving such that a more safe brake operation can be performed.
- the side brake does not need to be employed such that consumable components for constituting the side brake do not need to be provided or an action for operating the side brake does not need to be taken.
