Abstract: A climate control system in a vehicle. The system comprises a first control module configured to: i) receive a first temperature measurement associated with a passenger compartment of a vehicle; ii) compare the first temperature measurement to a temperature set point value; and iii) in response to the comparison, determine a first error value associated with a difference between the first temperature measurement and the temperature set point. The system further comprises a temperature control module configured to receive the first error value and, in response, to adjust the light transmissivity of at least one window the vehicle.

Abstract: A solar loading-based system includes a memory, a disturbance prediction module, a cabin temperature estimation module and a thermal control module. The memory stores a cabin thermal load model of an interior cabin of a host vehicle and a solar load prediction model. The disturbance prediction module: receives signals indicative of states of cabin thermal actuators and comfort metrics; and predicts an effect of solar loading over a known portion of a predicted route including predicting cabin temperatures based on the solar load prediction model, the states of the cabin thermal actuators, and the comfort metrics. The cabin temperature estimation module, based on the cabin thermal load model, determines a first comfort metric based on the predicted cabin temperatures. The thermal control module controls cabin thermal actuators to adjust cabin states, including the first comfort metric, to respective target values based on the predicted effect of solar loading.

Abstract: A climate control system includes a memory, a compensation module, and a climate control module. The memory is configured to store images captured by one or more image sensors. The compensation module is configured to: based on the images, estimate a clothing level of a first occupant in an interior cabin of a vehicle or receive the clothing level from at least one of an edge computing device or a cloud-based network device; determine a first EHT setpoint; and determine a first resultant EHT based on the clothing level and the first EHT setpoint. The climate control module is configured to: determine a first EHT error based on the first resultant EHT and a cabin temperature setpoint; determine a control value based on the first EHT error; and set climate control parameters to control a temperature of a first zone within the interior cabin based on the control value.

Abstract: A water condensation mitigation system for a battery pack having a battery housing system configured to generally surround and contain the battery pack. The battery housing system having a housing having a plurality of wall surfaces defining a housing volume. The housing volume being sized and shaped to contain the battery pack. The housing further having at least one aperture formed in at least one of the plurality of wall surfaces. A pressure valve member being operably mounted relative to the aperture of the housing that is configured to accommodate pack air volume changes and/or temperature changes in the housing volume.
