Abstract
A suspension control system for a vehicle includes a pressure increasing module and a compressor control module. In response to a startup of the vehicle, the pressure increasing module: selectively sets a pressure increase signal to a first state when an air pressure within air bags of a suspension system is less than a predetermined pressure; and selectively sets the pressure increase signal to a second state when the air pressure is greater than the predetermined pressure. In response to the startup of the vehicle, the compressor control module: operates an air compressor of the suspension system when the pressure increase signal is in the first state; and disables operation of the air compressor when the pressure increase signal is in the second state.

A suspension control system for a vehicle, comprising:
- a pressure increasing module that, in response to a startup of the vehicle:
- selectively sets a pressure increase signal to a first state when an air pressure within air bags of a suspension system is less than a predetermined pressure;
- and
- selectively sets the pressure increase signal to a second state when the air pressure is greater than the predetermined pressure;
- and
- a compressor control module that, in response to the startup of the vehicle:
- operates an air compressor of the suspension system when the pressure increase signal is in the first state;
- and
- disables operation of the air compressor when the pressure increase signal is in the second state.
A suspension control method for a vehicle, comprising:
- in response to a startup of the vehicle:
- selectively setting a pressure increase signal to a first state when an air pressure within air bags of a suspension system is less than a predetermined pressure;
- and
- selectively setting the pressure increase signal to a second state when the air pressure is greater than the predetermined pressure;
- and
- in response to the startup of the vehicle:
- operating an air compressor of the suspension system when the pressure increase signal is in the first state;
- and
- disabling operation of the air compressor when the pressure increase signal is in the second state.
