Vehicle compressor control system and method
First Claim
1. A vehicle comprising:
- an engine;
a compressor having a target speed;
a sensor for sensing an environment parameter;
another sensor for sensing an on/off state of the engine; and
a control module configured to (i) determine a maximum speed of the compressor based on the environment parameter and the on/off state and (ii) limit a speed of the compressor to the maximum speed if the target speed is greater than the maximum speed.

Abstract
A vehicle compressor is controlled based on an environment parameter and a vehicle status parameter. In at least one embodiment, a temperature control system for a vehicle including an engine is provided. The system includes a compressor having a target operating speed. The system also includes an environment sensor arrangement configured to sense an environment parameter and a vehicle status sensor arrangement configured to sense a vehicle status parameter. The system further includes a control module that determines a maximum operating speed of the compressor as a function of both the environment parameter and the vehicle status parameter. The control module limits an operating speed of the compressor to the maximum operating speed if the target operating speed is greater than the maximum operating speed.

9. A method for controlling a vehicle compressor having a target operating speed, the method comprising:
-
receiving a signal indicative of an environment parameter; receiving a signal indicative of a vehicle status parameter, wherein the vehicle status parameter comprises a speed of an engine cooling fan; at least one of increasing and decreasing the target operating speed based on one of the environment parameter and the vehicle status parameter to determine a modified operating speed; at least one of increasing and decreasing the modified operating speed based on the other of the environment parameter and the vehicle status parameter to determine an optimum operating speed; and operating the compressor at the optimum operating speed. - View Dependent Claims (10, 11, 12, 13, 14, 15)
