A vehicle thermal management control method, controller and system

Abstract

The invention discloses a vehicle thermal management control method. The control method includes: acquiring temperature information of a target vehicle; determining a thermal management mode of a motor circuit of the target vehicle according to the temperature information; corresponding to the thermal management mode according to the thermal management mode The calculation method and the temperature information calculate the target control amount of the temperature control equipment, the temperature control equipment includes water pumps and fans, and the target control amount includes the water pump target control amount and the fan target control amount; according to the target control amount control The temperature control equipment operates. The invention also discloses a thermal management controller and a control system with the controller. The invention can actively control the temperature control equipment of the motor circuit, and has the advantages of improving work efficiency, saving energy, reducing NVH noise, and the like.

Description

technical field [0001] The invention relates to a vehicle thermal management control method, in particular to a thermal management control method applied to a hybrid vehicle, and also to a controller and a system. Background technique [0002] A hybrid vehicle uses a combination of an internal combustion engine and an electric motor as the power source of the vehicle. During the working process of the vehicle, the heat at the engine is relatively high, which will affect the working effect of each device, so it needs to be cooled and dissipated. At present, the mainstream motor loop thermal management control strategy is that the thermal management controller controls the work of the water pump and the fan according to the input of the IPU. It only passively accepts the input command and cannot actively judge. This also leads to a single control strategy, which cannot make appropriate changes according to the real-time state of the motor circuit, resulting in a certain amount...

At present, the mainstream motor circuit thermal management control strategy is that the thermal management controller controls the work of the water pump and fan according to the IPU input, and it only passively accepts the input command and cannot actively judge

This also leads to a single control strategy, which cannot make appropriate changes according to the real-time state of the motor circuit, and there is a certain waste of energy and excess control.
