Abstract
The disclosure herein relates to a vehicle compressor control apparatus and control method, and more particularly to a vehicle compressor control apparatus for controlling compressor operating rate to allow braking according to brake negative pressure, while maintaining a minimum level of operation of the compressor. By preventing compressor deactivation during braking, the control apparatus assists in preventing moisture build-up of moisture on a windshield that decreases visibility for a driver and increases safety concerns. The apparatus includes: a compressor that reduces a temperature by compressing an air conditioner coolant; a data sensor that detects status data; and a controller that determines whether a brake negative pressure margin rate meets a first reference value when the status data satisfy a predetermined condition, and sets a compressor operating accordingly when the brake negative pressure margin rate meets a first reference value.
