Engineering desire: How Mercedes-Benz is shaping the future of luxury and efficiency - Mercedes-Benz Group Media - DRIVE PILOT builds on the surround sensors of the Driving Assistance Package and comprises additional sensors that Mercedes-Benz considers indispensable for safe conditionally automated driving. These include LiDAR, as well as a camera in the rear window and microphones, especially for detecting blue lights and other signals from emergency vehicles. There is also a wetness sensor in the wheel well. The S-Class with optional DRIVE PILOT also has redundant steering and braking systems and a redundant on-board electrical system. This ensures that it remains manoeuvrable even if one of these systems fails and enables safe handover to the driver.
