Porsche Cayenne Hybrid Components

www.eurocarnews.com - The heart of these technologies is the powerful Hybrid Manager, which requires some 20,000 data parameters to operate (compared to a conventional engine control unit that operates on less than one-third of the data). Since a parallel full hybrid operates in three classic hybrid modes power generated by the combustion engine and electric motor, power generated by the combustion engine only, and power generated by the electric motor only the Hybrid Managers main function is to seamlessly coordinate these modes to deliver optimal performance and efficiency.

With a clutch being the key connection between the combustion engine and the electric motor, the Hybrid Manager has the tough job of providing smooth but quick switching among the three hybrid modes without delay or a noticeable transition felt by the driver and passengers. For example, the Cayenne S Hybrid can motor along solely on electric power for up to 1.2 miles with the combustion engine off, and the Hybrid Manager will fire up the engine as soon as the driver presses the accelerator, increase engine speed appropriately and engage the clutch to transfer power to the transmission without the driver or passengers noticing what is happening. And, it does this within just 300 milliseconds.
