Abstract:
1. A control system for an electric vehicle equipped with a driving electric motor which is actuated by electric power, as supplied from a vehicle-driving battery, to drive a wheel of an electric vehicle, a power generating motor which is actuated by an internal combustion engine to provide electric power to the vehicle-driving battery, and an air conditioner which works to regulate temperature in a cabin of the electric vehicle, comprising: an air condition controlling unit which is configured to control driving of the internal combustion engine based on the preset operating point and control an operation of the internal combustion engine so as to keep an output therefrom at a given constant level to actuate the air conditioner in response to an air conditioning request; and a charging control unit which is configured to determine an amount of charge in the vehicle-driving battery and that the electric vehicle is at a stop, and control driving of the internal combustion engine based on a preset operating point and control the operation of the internal combustion engine so as to keep the output at the given constant level to actuate the power generating motor for charging the vehicle-driving battery when the amount of charge in the vehicle-driving battery is determined to be lower than or equal to a given threshold value, and the electric vehicle is determined to be at a stop.
