1. A vehicle height control apparatus, comprising:

  • a suspension controller configured to control vehicle height;

    a lateral acceleration sensor;

    a braking controller configured to determine a road surface condition on the basis of a difference between a lateral acceleration measured by the lateral acceleration sensor and a lateral acceleration calculated using a vehicle speed value and a steering angle value, the braking controller determining vehicle height information to be reflected in the suspension controller on the basis of the measured lateral acceleration and a roll angle presumed on the basis of the determined road surface condition and the measured lateral acceleration; and

    an interface unit performing data communication between the braking controller and the suspension controller.
