Optimization of the control algorithm for a vehicle with a hybrid power plant

Abstract

Along with the rapid growth of fuel prices, the increase of car fleet in the world, including Russia, has focused on reducing fuel consumption by vehicles. One of the ways that can reduce the consumption of hydrocarbon fuels is to use vehicles with an electromechanical powertrain. The energy source for such vehicles is both an internal combustion engine and an electric motor. The results of a study of fuel consumption by a hybrid vehicle with various control algorithms are presented. The methods of mathematical and simulation modeling were used. Fuel consumption data is given when using various algorithms for turning on the gasoline internal combustion engine, depending on the vehicle speed. As a result of simulation modeling, it was found that in order to ensure the greatest fuel economy, it is necessary that the gasoline engine starts when the car reaches a speed of at least 60 km/h, then fuel consumption in the urban driving cycle is reduced by 50% compared to the gasoline engine start mode at a speed of 30 km/h.
