A chassis control system of a vehicle is provided to reduce the weight of the vehicle and improve fuel efficiency by reducing use of wire ring. A chassis control system comprises an accelerator pedal sensor(20) for sensing the operation of an accelerator pedal of a driver; a steering angle sensor(40) or sensing the operation of a steering wheel of the driver; a parking sensor(10) for sensing a rear object during rearward movement of a vehicle; a passenger sensor(30) mounted on a passenger seat so as to sense the vertical vibration in accordance with the travel of the vehicle; and an integrated electronic control unit(100) for performing fail safe function for the signals input from sensors. The accelerator pedal sensor, the steering angle sensor, the parking sensor, and the passenger sensor are connected to the integrated electronic control unit through respective interface units(10a,20a,30a,40a). The accelerator pedal sensor is connected to a throttle sensor(70) which controls injection of fuel of an engine in accordance with the signal output from the accelerator pedal sensor. The steering angle sensor is connected to a wheel speed sensor, a horizontal acceleration sensor(50), and a rear angle sensor(60). The integrated control unit connected to the sensors, is connected to an ABS, TCS and ESP(110) for controlling a chassis on the basis of the signals output from the sensors.
