IPC: B60L50/16
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To improve the fuel efficiency of an electric vehicle by securing sufficient changes of actuating regenerative braking. SOLUTION: When a vehicle speed sensor 36 detects that the vehicle speed is slow, an SOC value (state of charging of a battery), a charging target of a battery 26, is changed to a smaller value. When a process is performed that the torque load of regenerative braking is reduced if the SOC value of the battery 26 exceeds a given threshold value, the detection of the slow speed by the vehicle speed sensor 36 changes the threshold value to a larger value. This method makes is possible to increase chances of actuating the regenerative braking and thereby to improve the energy efficiency of an electric vehicle.

Abstract: PURPOSE: To adjust the rpm of a rotary grille to the optimum value even though the rpm of fans varies in great extent by controlling the rotation of the rotary grille by varying the magnetic resistance in a magnetic path of a rotary dynamic braking body via a speed increasing mechanism.  
     CONSTITUTION: The rotation of the rotary grille 6 is increased by a series of gears, a conductive disk 12 is rotated at a high speed, magnetic fluxes caused by a permanent magnet 13 are cut by the conductive disk 12, and the dynamic brake is applied to the conductive disk 12. In general, the dynamic braking torque is approximately proportional to the rpm and to the square of the strength of the magnetic field. Therefore, the strength of the magnetic field in a gap 17 can be sequentially reduced equivalently when a pole piece 15' is overlapped with a pole piece 15, when the pole piece 15 is advanced by 90°, and when it is advanced by 180°, by manipulating a knob. Therefore, even though the rpm of the fans varies broadly, the rpm of the grille 6 can be brought to the optimum value.
