摘要： Changes in ambient light intensity are detected by processing image data (12) from an image capture device (2) to determine, iteratively, a signal -to- noise ratio of the image data (12). The signal-to-noise ratio is a ratio of average to variance of pixel values for some of the pixels (14) forming the image (13). A control output (15) is generated, based on the signal-to-noise ratio (SNR), that is responsive to changes in ambient light intensity. The control output (15) is used control a light source (16, 17, 18) of a vehicle (1).

摘要： A method is disclosed for controlling an engine assembly comprising an internal combustion engine and an exhaust gas treatment apparatus. The aftertreatment assembly may require cleaning from time to time, and where this involves active thermal management of the aftertreatment assembly, the method involves performing the following steps: (a) imposing a first limit on engine speed; (b) awaiting an engine safe state; and (c) implementing a cleaning process comprising: (i) injecting fuel into the engine such that the fuel passes through the engine without combusting for the fuel to combust in a diesel oxidation catalyst so as to target an increase in exhaust gas temperature in the diesel oxidation catalyst; and (ii) removing the first limit on engine speed and targeting an engine speed set point, wherein the engine speed set point is at a higher speed than the first limit on engine speed.

摘要： A method of monitoring the usage of an internal combustion engine is provided. The method comprises performing an engine monitoring routine using a local monitoring device directly attached to an internal combustion engine. The engine monitoring routine includes generating a plurality of data points representative of the crankcase pressure of the internal combustion engine using a pressure sensor of the local monitoring device, processing the generated data points to determine a first value representative of a firing frequency of the internal combustion engine, generating an aggregated summary of the internal combustion engine usage based on the first value, and transmitting identification data for the local monitoring device and the aggregated summary from the local monitoring device to a remote application. The remote application processes the transmitted aggregated summary based on the transmitted identification data to determine engine speed usage data for the internal combustion engine.
