In this paper, a design methodology is developed to condtruct the gear shift map for the automotive transmissions used in conventional and hybrid electric vehicles. The methodology utilizes an optimal gear shift strategy to derive the optimal gear shift patterns over a wide range of driving profiles. Then, statistical theory is applied to analyse the obtained gear shift patterns for a gear shift map. The designed gear shift map improves the fuel economy and driveability. It is consistent, robust to shift busyness and real-time implementable. The design process is flexible and time efficient such that applicability to various powertrain systems configured with discrete-ratio transmissions is possible. Validation on a test vehicle proves the effectiveness of the design methodology.
