The New Automotive Stability Control (Asc) of the 3-Series Bmw Diesel Passenger Cars
Published November 07, 1995 by Institution of Mechanical Engineers in United Kingdom
The first Diesel-ASC for passenger cars was jointly developed by ITT-AE and BMW and is available for both 6-cylinder Diesel versions of the 3-series BMW. Like the ASC for petrol engine powered cars the new Diesel-ASC is based on the basic ABS. Suitable extensions of the ABS hydraulic unit allow an individual brake application at the driven axle to prevent excessive wheel slip.
The Diesel-ASC defines control circuits for engine and brake. The engine control is carried out via a serial data link (CAN) between the ASC controller and the Digital Diesel Electronics DDE. The engine torque interface between the ASC and the DDE is used for engine drag reduction also. By this interface structure the reduction of positive and negative wheel slip becomes possible.
