Abstract
A vehicle height control apparatus includes a suspension controller for controlling vehicle height, a lateral acceleration sensor, a braking controller determining 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 and a steering angle, 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.
