    The present invention relates to an active roll control apparatus for a vehicle, which enables to effectively control the function of a stabilizer or ER fluid of an anti-roll system for controlling rolling occurring while driving of a vehicle. According to the present invention, when the roll angle is detected from the acceleration sensor 1, the speed sensor 2, the steering angle sensor 3, and the control signal is output from the ECU 4, the voltage generator 5 generates a voltage of a predetermined level. In addition, since the voltage amplification part 6 amplifies a predetermined level and applies it to the cylinder 8 and the ER 9, the applied voltage reacts with the fluid of the ER 9 to separate the step bars 11 at the front and rear of the vehicle. It has an effect that can be controlled according to the angle.

    Vehicle Active Roll Control
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle, and in particular, an active roll control device for a vehicle that enables effective control of a function of a stabilizer (STABIL1ZER) or an ER (ELECTRO-RHEOLOGICAL) fluid of an anti-roll system that controls rolling occurring while the vehicle is running. It is about.
    In general, the vehicle is equipped with an active roll control system for preventing the vehicle body from leaning to one side when cornering the vehicle. In the past, rolling detection was performed using a stabilizer or a pressure reducing valve.
    The present invention has been made in response to such a conventional active roll control system for vehicles, and a step bar (STAB BAR) and a cylinder are installed in a vehicle stabilizer device to continuously apply voltage to the ER fluid with a high voltage generator. It is an object of the present invention to provide an active roll control device for a vehicle that can effectively control the roll when cornering.
    The present invention for achieving the above object is an angle sensor unit for detecting the steering angle, vehicle speed, vertical acceleration, the ECU to receive the information sensed by the sensor unit to perform a corresponding control roll, according to the control of the ECU And a voltage generator for generating a voltage of a predetermined level, a voltage amplifier for amplifying the voltage generated by the voltage generator to a predetermined width, a cylinder and an ER operated by a voltage amplified by the voltage amplifier. It is characterized by.

    Hereinafter, with reference to the accompanying drawings an embodiment of the active roll control device for the present invention will be described in detail as follows.
    1 is a configuration diagram of the present invention, an acceleration sensor 1 for detecting an acceleration of a vehicle, a speed sensor 2 for detecting a speed of a vehicle, a steering angle detection sensor 3 for detecting a steering angle, and the angle sensor 1 ECU 4 which performs control by receiving the information sensed by -3), a voltage generator 5 which generates a voltage (e.g., 0-5V) under control of the ECU 4, and the voltage A voltage amplifier 6 for amplifying the voltage generated by the generator 5 to a predetermined level, and a cylinder 8 installed in the lower portion 7 of the vehicle body and operating according to the voltage amplified by the voltage amplifier 6; And ER 9, reference numeral 10 in the figure is a support rubber installed in the lower body 7, and 11 is a step bar connected to the ER 9 in the cylinder 8.
    According to the present invention configured as described above, the angle of the roll is changed when cornering of the vehicle. In this case, the roll angle is determined from information of acceleration, speed, and steering angle detected by the acceleration sensor 1, the vehicle speed sensor 2, and the steering angle sensor 3 of the vehicle. It is detected and input to the ECU 4.
    Therefore, the ECU 4 outputs the corresponding control signal from the information of the roll angle input, so that the voltage generator 5 generates a voltage of 0-5V by this control signal.
    In addition, since the voltage generated in this manner is amplified to a predetermined level in the voltage amplifier 6 and applied to the step bar 11 and the cylinder 8, the voltage applied to the step bar 11 and the cylinder 8 in this way. In response to the fluid in the ER 9, the stepping bar 11 separating the front and rear ends of the vehicle is controlled according to the degree of the roll angle.
    According to the active roll control apparatus for a vehicle according to the present invention as described above, it is possible to improve the running stability, adjustment stability, and ride comfort because the change in the roll angle that occurs during cornering of the vehicle is controlled.
