With an increase in car production every year, the fuel consumption increases, and hence the pollution increases due to emissions from the internal combustion engines. The car needs a source of propulsion, which develops maximum torque at zero with minimum pollution. The classic ICE cannot achieve this. Instead, electric vehicles are used which reduces pollution to a greater extent. The vehicle which uses two power sources is called hybrid electric vehicle.
To increase the fuel efficiency, the internal combustion engine extracts more energy. But it reduces the exhaust temperature. At lower temperatures, the chemical reactions associated with the combustion of unburned hydrocarbons may not occur. The increase in compression ratio enhances fuel economy which in turn increases the temperature of ICE. This increase in temperature increases both CO and other nitrogen oxides which causes pollution. The important functions of the control systems in hybrid electric vehicles are to maximize fuel efficiency and minimize exhaust emissions in spite of their conflicting nature as mentioned before.
This chapter starts with a brief introduction to hybrid electric vehicles and control systems. Then, the need for control of hybrid electric vehicle is elucidated along with the classic and current techniques to control HEV.
