A Case Study in Applying a Product Line Approach for Car Periphery Supervision Systems



SAE 2001 World Congress
Authors Abstract
Car Periphery Supervision (CPS) systems comprise a family of automotive systems that are based on sensors installed around the vehicle to monitor its environment. The measurement and evaluation of sensor data enables the realization of several kinds of higher level applications such as parking assistance or blind spot detection. Although a lot of similarity can be identified among CPS applications, these systems are traditionally built separately. Usually, each single system is built with its own electronic control unit, and it is likely that the application software is bound to the controller's hardware. Current systems engineering therefore often leads to a large number of inflexible, dedicated systems in the automobile that together consume a large amount of power, weight, and installation space and produce high manufacturing and maintenance costs.
This paper reports on an initiative undertaken by the Bosch Group in applying a product line development approach to develop CPS systems economically. Product line development represents a multi-system engineering approach which takes common and variable aspects between systems in the same application domain into account. It provides a basis to develop a line of products economically based on a common system architecture and reusable components.
A product line allows the degree of reusability to be optimized across different systems while simultaneously preserving the overall quality. This supports the need to develop more integrated and flexible multi-functional systems quickly and cost-effectively. The purpose of this paper is to report on the experiences and results obtained from a case study in developing a product line of CPS systems.
