    Optimization of Hybrid Vehicle Driving

  • Original language description

    The predictive optimization of minimum energy consumption and low carbon dioxide emissions at known route is becoming the standard tool for the extended horizon driving control of hybrid vehicles. The problem occurs if the capacity of accumulators is sufficient for distance much longer than the extended horizon is. The driving strategy should assess the possibilities of re-charging an accumulator for the optimum combination of prime mover power (today, an internal combustion engine) and an electric motor power booster, taking the rest of trip into account. Adaption for changed traffic density or weather is the next step of future control systems, finding the best compromise between trip time and total energy consumption. The “brute force” optimization of many thousands independent variables for the model with detailed description of vehicle components is possible, if performed out of real time only, using dynamic programming techniques and cloud computing devices. The paper describes fast model and optimization algorithm for the best carbon dioxide emissions, which finds the local optimum distribution of power between an engine and a motor/generator, applying the numerical solution for finding the optimum of energy consumption, described by a regression powertrain model. It takes the efficiency of stored electric energy use in a motor during the relevant rest of trip into account by iterative way. The model limits number of optimization variables by semi-heuristic algorithm of speed schedule in a route section. Then, the eco-driving optimization can be done by genetic algorithm. Currently, the model describes single-accumulator parallel or serial hybrids including differential power splitter, but it can be extended to all hybrid layouts.
