Vehicle temperature control system

Abstract

The embodiment of the invention provides a vehicle temperature control system which comprises a vehicle-mounted control unit temperature control flow path for controlling the temperature of a vehicle-mounted control unit by passing two or more temperature control branches, wherein at least one temperature control branch passes through the interior of the vehicle-mounted control unit; a battery temperature control flow path which is used for carrying out temperature control on the plurality of battery units, and is shunted to a plurality of parallel branches to respectively carry out temperature control on the plurality of battery units, wherein each parallel branch corresponds to one battery unit; a heat exchange unit which comprises an output port and a backflow port and is used for providing temperature control fluid for the vehicle-mounted control unit temperature control flow path and the battery temperature control flow path; and a control valve unit which is used for controllingthe vehicle-mounted control unit temperature control flow path and the battery temperature control flow path to be connected in parallel or in series. Through the vehicle temperature control system, layout of the temperature control flow path can be optimized, and the temperature control efficiency of the vehicle-mounted control unit and the battery is improved.

Description

technical field [0001] The present application relates to a vehicle temperature control system, which is applied to the adjustment and control of the vehicle's on-board control unit and battery temperature. Background technique [0002] In recent years, automotive intelligent driving has shown a trend of high enthusiasm, high investment, and rapid technological development from research and development to industry. In the field of intelligent driving, the core structural component is the on-board chip. [0003] The Institute of Electrical and Electronics Engineers (IEEE) 802.1 standard was established at the end of 2018 and began to formulate relevant standards for vehicle-mounted Ethernet communication (P802.1DG-TSN Profile for Automotive In-Vehicle Ethernet Communications). The electrical architecture (Electrical / Electronic Architecture, referred to as E / E architecture) evolution proposal refers to the evolution of the automotive E / E architecture from the traditional dist...

AI Technical Summary

Problems solved by technology

The working stability of the on-board chip is an important guarantee for the safety of intelligent driving; if the temperature of the on-board chip is too high, it will inevitably affect the working efficiency of the on-board chip and reduce the stability of the chip. Therefore, it is necessary to avoid The temperature is too high when working

[0005] On the other hand, when the vehicle is driving in a cold environment, the control units such as the on-board chip will also be affected by the low temperature, and the stability during operation cannot be guaranteed.
