Abstract
A control system for a hybrid vehicle includes: an electric heater configured to heat a catalyst of an internal combustion engine; a position determination unit configured to determine whether the hybrid vehicle is located in an exit area of a low emission zone where operation of the internal combustion engine is supposed to be restricted, the exit area being an area adjacent to a boundary of the low emission zone; and a heater control unit configured to turn on the electric heater when the position determination unit determines that the hybrid vehicle is located in the exit area.

A control system for a hybrid vehicle, comprising:
- an electric heater configured to heat a catalyst of an internal combustion engine;
- a position determination unit configured to determine whether the hybrid vehicle is located in an exit area of a low emission zone where operation of the internal combustion engine is supposed to be restricted, the exit area being an area adjacent to a boundary of the low emission zone;
- and
- a heater control unit configured to turn on the electric heater when the position determination unit determines that the hybrid vehicle is located in the exit area, wherein:
- the hybrid vehicle includes the internal combustion engine and an electric motor;
- and
- a drive mode of the hybrid vehicle is switched between an electric vehicle mode and a hybrid vehicle mode, the electric vehicle mode being a mode in which the internal combustion engine is stopped and the electric motor is operated, and the hybrid vehicle mode being a mode in which the internal combustion engine and the electric motor are operated.
A control method for a hybrid vehicle, the control method comprising:
- determining whether the hybrid vehicle is located in an exit area of a low emission zone where operation of an internal combustion engine is supposed to be restricted, the exit area being an area adjacent to a boundary of the low emission zone;
- and
- turning on an electric heater configured to heat a catalyst of the internal combustion engine, when determination is made that the hybrid vehicle is located in the exit area, wherein:
- the hybrid vehicle includes the internal combustion engine and an electric motor;
- and
- a drive mode of the hybrid vehicle is switched between an electric vehicle mode and a hybrid vehicle mode, the electric vehicle mode being a mode in which the internal combustion engine is stopped and the electric motor is operated, and the hybrid vehicle mode being a mode in which the internal combustion engine and the electric motor are operated.
