  • Variable blower controller for vehicle
    Patent number: 6871126
    Abstract: A variable blower controller for controlling the blower speed of a climate control system of a vehicle includes a microprocessor which is operable to variably control the blower speed of a blower motor of the climate control system. The variable blower controller provides for smart power management of the blower to avoid high-power dissipative modes when system temperatures are above “safe” levels. The smart power management objective is met by keeping the field effect transistor junction temperature away from design limits or threshold levels where possible. The microprocessor utilizes software and may use a combination of inputs to calculate these levels.
