Remote management method for thermal system of hybrid vehicle

Abstract

The invention discloses a remote management method for a thermal system of a hybrid vehicle. The remote management method comprises the steps that remote transmission data of an ECU of a new energy electric vehicle is acquired; at a remote management software terminal, the remote transmitting data of the new energy electric vehicle is subjected to processing including error correction and validation, interpolation, and redundancy check to obtain a remote transmission data segment to be processed; and the remote transmission data satisfying the requirements is processed by the TPEG decoding algorithm; the remote transmission data segment to be processed is subjected to data reduction operation; the remote transmission data obtained by the data reduction is analyzed and compared; and the software terminal which meets upgrade conditions is upgraded according to the comparison result, the upgrade operation is performed by calling a software upgrade function module, and the software upgradefunction module mainly includes analysis of original upgrade files and is used for installing the original upgrade files.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a remote management method for a heat system of a hybrid vehicle. Background technique [0002] With the occurrence of a series of environmental problems such as global warming, the gradual reduction of fossil energy, the destruction of the ozone layer, air pollution, smog, and sandstorms, people's awareness of environmental protection is increasing, and automobiles are one of the main factors of environmental problems. The contribution of its energy-saving and emission-reduction effects to environmental protection has gradually attracted the attention of governments and major vehicle manufacturers. In recent years, the requirements of fuel consumption regulations have become more and more stringent. The emission reduction and emission reduction of traditional vehicles can no longer meet the more stringent requirements of regulations on fuel consumption an...

Problems solved by technology

[0003] For plug-in hybrid electric vehicles, its position between traditional fuel vehicles and pure electric vehicles makes it have a special treatment method in terms of vehicle thermal management. Currently, most hybrid vehicles on the market use belt The conventional single-cooling air conditioner for battery cooling plus the thermal management mode of high-pressure water-cooled electric heating equipment (PTC), in summer, the cooling of the car and the battery cooling rely on the single-cooling air conditioner, while the heating in winter uses PTC or the engine as the heat source, but this conventional The heating mode has certain disadvantages. When heating is required in winter, if PTC heating is used, the cruising range of the vehicle in pure electric mode will be reduced by more than 50%. If the engine is used to provide heat for the passenger compartment, there is no pure electric mode available in winter. In use, the advantages of low fuel consumption and emission in the pure electric mode of hybrid vehicles cannot be fully utilized, and the thermal system of hybrid vehicles cannot be remotely managed
