  • Patent number: 8527095
    Abstract: A cooling system constructed to cool down an accumulator mounted on a motor vehicle is herein presented. The cooling system sequentially controls an air blower to restrict the air blow to the accumulator, controls the air blow mode switchover module to switch over the active air blow mode after restriction of the air blow to the accumulator, and controls the air blower to release the restriction of the air blow to the accumulator after the switchover of the active air blow mode by the air blow mode switchover module.

  • Publication number: 20090248204
    Abstract: The position of a damper is changed over to switch over the cooling mode between an inside air intake mode and an A/C intake mode. In the inside air intake mode, the air inside a passenger compartment of a motor vehicle is taken in and directly blown to a battery by the operation of a battery blower fan. In the A/C intake mode, the air cooled down by an air conditioner (evaporator) is taken in and blown to the battery by the operation of the battery blower fan. When the detected vehicle speed V is not lower than a preset reference speed Vref, the position of the damper is immediately changed over (steps S240 to S260). When the vehicle speed V is lower than the preset reference speed Vref, on the other hand, the operation amount of the battery blower fan is restricted to a preset limit level Qlim, prior to the changeover of the position of the damper (steps S220 to S260).

  • Patent number: 7129668
    Abstract: An actuator control device includes an electrical control unit for detecting the present positions of output shafts of servo motors, and communicating with control circuits for driving the output shafts of the servo motors to target stop positions on the basis of the present positions thus detected. When it is judged that a present position of one of the output shafts thus receives is abnormal, the electrical control unit corrects the present position and transmits the corrected present position to the appropriate control circuit.
