Abstract:
A system for automatically controlling a defog/defrost function of a vehicle climate control system includes a controller configured to calculate an ambient dew point temperature value from a plurality of inputs received from a sensor array. The controller is further configured to set a condensation indicator if a calculated difference between a window exterior surface temperature value input received from the sensor array and the calculated ambient dew point temperature value is less than or equal to a predetermined threshold value. The controller actuates the vehicle climate control system defog/defrost function and/or a window wiper system in response to the set condensation indicator.
Abstract:
This disclosure details integrated thermal management systems for thermally managing electrified vehicle components. Exemplary integrated thermal management systems may include a thermal module assembly that may be integrated into a front end structure of a flexible modular platform of the electrified vehicle. The integrated thermal management systems may be controlled in a plurality of distinct thermal control modes for thermal managing various subcomponents and for addressing various vehicle auxiliary loads (e.g., passenger cabin heating loads, passenger cabin cooling loads, etc.).
Abstract:
A method, comprising during a vehicle engine cold start, opening a first valve coupled between a first container containing an adsorbent and a second container containing an adsorbate, circulating a first fluid through a first conduit coupled to a first heat exchanger located within the first container and a second heat exchanger located outside the first container, and circulating a second fluid through a second conduit coupled to the second heat exchanger. In this way, heat may be generated at the adsorber during a cold start and subsequently transferred to the cooling jacket of the vehicle engine and/or other vehicle compartments, thereby decreasing the warm-up time for the engine.

Abstract:
Systems and methods for operating a heater for a passenger cabin of a vehicle. In one example, fan speed of an evaporator cooling fan is adjusted to improve heating efficiency. In particular, fan speed is incrementally increased and maintained at the higher speed if output power of a compressor is reduced by more than an amount of power used to incrementally increase the fan speed.
Abstract:
A heat exchanger is provided. The heat exchanger includes a plurality of stacked layers of fins, each fin including a repeated pattern of folds, the plurality of stacked layers of fins forming a plurality of repeating offset cell structures and a first coolant duct and a second coolant duct coupled to peripheral fins in the plurality of stacked layers of fins. The heat exchanger further includes a fan directing air through the repeating offset cell structures.
Abstract:
An emissions-control catalyst brick includes a plurality of formed metal ribbons that together define a repeating pattern of open cells. The ribbons are joined together in layers with the open cells of each layer offset from those of the adjacent layer. A catalyst wash coat is applied to the plurality of metal ribbons.
