An electronic height control system for a vehicle with multiple input signals is provided to adjust the occupant sitting height through a valve actuator by connecting an airbag with either an air supply source or atmosphere conductively and discharging/flowing the air from/to the airbag, using a valve. An electronic suspension system for a vehicle comprises a sensor(144), a valve, a motor, and a controller. The sensor detects distance between a vehicle axle(136) and a vehicle frame(114). The valve includes an inlet port connected to a supply source of a fluid, an operating port connected to a fluid bag, and an exhaust port connected to atmosphere. The motor is connected to the valve to operate the valve selectively among a filled position where the input port is connected to the operating port conductively, a discharged position where the operating port is connected to the discharging port conductively, and a neutral position where the ports are conductively divided. The controller is connected to the sensor to receive sensed signals. The controller includes a master controller and a suspension controller.
