ABSTRACT:
The present invention relates to an electronic controlled suspension apparatus capable of stopping vehicle height control when a vehicle turns and performing the vehicle height control when the vehicle goes straight ahead by using vehicle height sensors instead of a steering angle sensor, and a vehicle height control method of the electronic controlled suspension apparatus. To this end, there is provided an electronic controlled suspension apparatus, including a plurality of vehicle height sensors for measuring a height of a vehicle; a vehicle height adjusting actuator operable to adjust the height of the vehicle; air springs controlled by the vehicle height adjusting actuator; and an electronic controlled unit (ECU) for calculating a height difference value between the left and right sides of the vehicle based on vehicle height signals received from the vehicle height sensors and determining whether to operate or stop the vehicle height adjusting actuator through the comparison of the calculated height difference value between the left and right sides of the vehicle with a predetermined reference value.
