Adaptive gear change strategy

A method enabling the determination of optimal gear shift engine speeds for each gear on a vehicle equipped with a multi-gear transmission consisting of:

• measuring and recording vehicle acceleration on a flat ground and over a full range of engine speeds allowed on each gear as measured data;
• and storing the measured data in non-transitory storage as a graph of acceleration vs. vehicle speed curves;
• and determining where the acceleration vs. vehicle speed curves intersect;
• and from a total gear ratio and rolling radius (or wheel diameters), determining the engine speed corresponding to a lower of the intersecting curves at a respective intersection point;
• and performing the measuring and storing on various slopes to infer the effect of gravity on the vehicle's acceleration;
• and a computing device having access to the measured data and which, by real-time observations of the physical behavior of the vehicle, including the current gear, observed acceleration, and vehicle speed;
• determining the optimal gear change speeds based on the stored acceleration speed vs. vehicle speed;
• and adjusting the optimal gear change speeds dynamically as a function of a currently observed slope onto which the vehicle moves;
• and adjusting the optimal gear change speeds dynamically as a function of any difference between an expected acceleration and the measured acceleration.
