Abstract
A control system for a turbocharger of a vehicle includes an enable module, an error module, a reduction module, and a boost module. The enable module is configured to: enable reduction in a boost pressure setpoint of a compressor of the turbocharger based on whether a fault exists, load on an engine, and a compressor outlet temperature; and generate an enable signal indicating whether reduction in the boost pressure setpoint is enabled. The error module configured to determine a difference between the compressor outlet temperature and a predetermined limit. The reduction control module is configured to, in response to the enable signal indicating reduction in the boost pressure setpoint is enabled, reduce the boost pressure setpoint based on the difference. The boost module is configured to adjust boost pressure output of the compressor based on the boost pressure setpoint.
