Servotronic with two control maps

[teachdocs]

A technical question for the forum:

The three settings for EDC appear to have more than an indirect effect on steering response from suspension changes. If I understand this correctly, they also relate to a specific steering servotronic control map.

Since there are only two steering maps, which of the two are paired with the "Normal" EDC setting? Or is it a blend of the two maps?

In developing the BMW M6 High-Performance Coupe, the engineers at BMW M GmbH have given particular attention to the steering system crucial to agile and safe motoring. Via special control maps, Servotronic steering management controls the degree of power assistance as a function of road and engine speed. This solves the basic conflict of interest between high power assistance for comfortable parking and low assistance in the interest of superior driving dynamics at high speeds.

Two different Servotronic control lines corresponding to the EDC mode currently in use allow two different configurations, one focusing on motorsport, the other on motoring comfort. In the former case with the sports-oriented control line, the steering is very direct giving the driver precise feedback under high lateral acceleration. This is important because of the extremely high speeds the M6 is able to reach in a bend. The comfort setting, in turn, places the emphasis on motoring comfort appreciated above all on long distances. A common feature shared by both map control lines is that they maintain the basic characteristics and feeling of the steering.

The steering is lighter in comfort mode than in standard and sport mode. The servotronic setting which turns the wheels further for each degree of steering wheel movement as the steering wheel gets further away from centre is constant regardless of EDC setting.

Hope that's clearer to you than to me.
