Abstract: A method and a device used for remote control by optical fiber signals and power over Ethernet includes a power sourcing equipment (PSE) outputting a direct current (DC) via at least one network cable to at least one powered device (PD). When the PSE receives a second restarting signal from a signal controller, the PSE stops supplying power to the at least one PD. An optoelectric signal converter converts an optical signal from an Ethernet Switch to a digital signal for the signal controller. When the optical signal is determined by the signal controller to be interrupted after a first time duration passes, the signal controller outputs the second restarting signal to the PSE for restarting. After restarting, the PSE re-powers the at least one PD. The at least one PD is restarted remotely without requiring working personnel at the location of the at least one PD, improving restarting efficiency.

Abstract: A turbocharger control method and related systems are provided. An operational command to control a level of boost provided by the turbocharger is received. In response to receiving the operational command, an exhaust gas recirculation (EGR) valve is instructed to move from a current position to a desired position. A time taken for the EGR valve to move from the current position to the desired position is determined. A maximum rise rate of exhaust manifold pressure corresponding to a predicted EGR valve position is determined. A permitted exhaust manifold pressure limit for the turbocharger is determined based on a current exhaust manifold pressure, the maximum rise rate of exhaust manifold pressure and the time taken. An operation of the turbocharger is controlled such that the permitted exhaust manifold pressure limit is not exceeded.

The system may access a knowledge library having catalogued prior situation data sets that describe situations encountered by the AV or other vehicles in a fleet. The AV control system may search the knowledge library for a similar situation encountered by a fleet vehicle. Once a similar situation is identified, the AV control system may identify one or more remedies that were executed to handle the prior situation, and execute the remedy to address the current situation.
