Definitions
- This invention relates to vehicle driver support and vehicle control systems that estimates future vehicle dynamics based on current vehicle operational parameters and driver control settings.
- the invention relates particularly, although not exclusively, to a system and method for giving advance warning to a train driver, in real time, of predicted train dynamics based on hypothetical future control setting regimes.
- the invention is desirably embodied as a cabin instrument and finds particular application in long freight train consists.
- Japanese Patent Document No. 58-075410 by Tokyo Shibaura Denki KK describes a driving command device for providing guidance as to the optimum vehicle control settings in order to conserve energy.
- the invention resides in a method of predicting, over a predetermined future time period, vehicle velocity which predictions utilize future vehicle control settings anticipated for that period, said prediction method including the steps of:
- FIG. 7 shows a conceptual diagram of a further artificial neural network (ANN) model contemplated by the invention.
- FIG. 8 is a conceptual diagram of a modified version of the ANN
- the vehicle control settings include throttle position, dynamic brake, locomotive brake cylinder pressure and wagon brake pipe pressure, whilst the vehicle operational parameters include vehicle velocity, for each of two locomotives 110 and 111.
- the operational parameter data and control setting data acquired in this way provides both present "real time" data, which is later stored in a memory arrangement (not shown) to provide historical operational parameter data and historical control setting data.
- the processor 104 is also coupled to a GPS track plan and section database 109 that includes topographical information for potential routes of travel of the train.
- the input HL referenced in the above tables is the number of neurons in the hidden layer of the artificial neural network.
- Parameter items 4 and 9 may be derived from the velocity predicted by the output from the first ANN model represented by Table 7, above.
