Abstract
Methods and systems for selecting an ambient temperature value for initializing an ambient temperature algorithm in a vehicle climate control system are described. The methods and systems include, by a controller, determining a risk that a prior stored ambient temperature value is inaccurate by comparing to a remotely sourced current ambient temperature value and calculating a risk factor. The controller selects an ambient temperature algorithm input from one of the prior stored ambient temperature value or a new ambient temperature value according to the calculated risk factor.
Claims15
A method for selecting an ambient temperature value for initializing an ambient temperature algorithm in a vehicle climate control system, comprising:
- by a controller, determining a risk that a prior stored ambient temperature value is inaccurate by comparing to a remotely sourced current ambient temperature value and calculating a risk factor;
- and
- by the controller according to the calculated risk factor, selecting an ambient temperature algorithm input from one of the prior stored ambient temperature value or a new ambient temperature value.
A system for selecting an ambient temperature value for initializing an ambient temperature algorithm in a vehicle climate control system, comprising:
- a vehicle climate control module comprising a controller in operative communication with a vehicle climate control system, wherein the controller is configured to:
- determine a risk that a stored ambient temperature value is inaccurate by comparing to a remotely sourced current ambient temperature value;
- and
- according to a calculated risk factor, provide an ambient temperature algorithm input by selecting one of the stored ambient temperature value or a new ambient temperature value.
