A vehicle waste heat recovery system for recovering thermal energy from exhaust gases discharged from an engine 12 of the vehicle, the system comprising: a first flow path 16 including a first turbocharging unit 20 and a first exhaust aftertreatment device 21; a second flow path including a second turbocharging unit 24 and a waste heat recovery device 28; a valve arrangement 22, 30, 32, 36 configured to control exhaust gas flow through the first flow path and the second flow path to open and close the first flow path and the second flow path independently of each other; sensing means arranged to provide a signal indicative of the engine load; and control means arranged to control the valve arrangement in response to the indicated engine load. A method of, a computer program for and a controller for operating a vehicle turbocharging system are also claimed, as are a readable medium for the computer program and a vehicle with the system. |
