摘要:
A system according to the principles of the present disclosure includes a variance determination module and a fault detection module. The variance determination module determines a variance of samples generated from a ride height signal. The ride height signal is output by a ride height sensor that detects a ride height of a vehicle. The fault detection module detects a fault in the ride height sensor based on the variance.
摘要:
A method of initializing operation of a shutter arranged relative to a grille opening in a vehicle having a power-plant includes detecting a start-up of the power-plant. The method also includes sensing a temperature of ambient air. The method also includes commanding the shutter to achieve a fully-opened position when the temperature of ambient air is above a predetermined value such that a flow of ambient air to the power-plant through the grille opening is substantially unrestricted. The method additionally includes commanding the shutter to achieve a fully-closed position when a temperature of the power-plant is maintained below a threshold value such that the flow of ambient air through the grille opening to the power-plant is substantially blocked. A vehicle using a controller configured to perform the above method is also provided.
摘要:
A system for controlling an aerodynamic shutter of a vehicle includes an ambient temperature estimation module that determines an ambient temperature. A shutter control module that determines whether to actuate the shutter based on the ambient temperature. The shutter control module also determines a predetermined period before selectively applying a predetermined torque value to the shutter. The predetermined period is selected based on the ambient temperature.

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.
