6. A compound cruise signal method for solar cars comprising the steps of:
-
setting a standard power consumption level using a present power consumption level of the motor or a standard consumption level established immediately prior to operation of cruise control, and setting a standard vehicle speed using the present vehicle speed or the standard vehicle speed established immediately prior to operation of the cruise control; setting a maximum vehicle speed and a minimum vehicle speed based on motor efficiency map data derived from the standard power consumption and the standard vehicle speed; determining present vehicle speed and comparing the same with said maximum and minimum vehicle speeds; calculating target power according to said standard power, standard vehicle speed, and present vehicle speed when the present vehicle speed is between said maximum and minimum vehicle speeds; and determining an output torque value such that target power becomes drive power consumption of the motor, and maintaining cruise control at a vehicle speed within a section of motor efficiency. - View Dependent Claims (7, 8, 9, 10, 11)
