Abstract

The invention discloses preconditioning for a hybrid electric vehicle. The hybrid electric vehicle (HEV) and a method of operation, which include a cabin, a battery, an emission aftertreatment catalyst, and a thermal management system coupled to a compressor and a chiller that each have cooling capacities and respective refrigerant and coolant distribution systems. The HEV also includes one or more controllers configured to precondition temperatures of the battery, cabin, and catalyst in response to a predicted vehicle start-time and / or a detected action that indicates likelihood of HEV start.The controller(s) utilize respective conditioning profiles for each of the battery, cabin, and catalyst to achieve the preconditioning temperatures at rates adjusted according to power availability from the battery and an external power source. The preconditioning is terminated upon HEV start or if the predicted start-time expires without HEV start. The HEV and the method are adapted to learn from changes in actual start-times and driver actions resulting in HEV starts or no-starts.

Description

technical field [0001] The present disclosure relates to preconditioning of batteries, cabins and exhaust aftertreatment catalysts of hybrid electric vehicles. Background technique [0002] In a hybrid electric vehicle (HEV), performance may be affected by the surrounding environment, which can introduce undesired temperature extremes to HEV components and systems. For example, in certain seasons and climates, the HEV passenger compartment may be uncomfortably cold or warm prior to operation. HEVs at northern latitudes may experience uncomfortably low temperatures, while HEVs at equatorial latitudes may experience uncomfortably high humidity and high temperatures. These extreme temperatures may affect the HEV during start-up and initial operation of the HEV, and may result in suboptimal performance and life cycles of the HEV battery, exhaust aftertreatment catalysts, and other HEV components and systems. Previous attempts to control the temperature of HEV components have i...
