Embodiment Construction

[0040] The present invention is described in detail below, which is a preferred example among various implementations of the present invention.

[0041] Cooling Fan Control Logic 1-6

[0042] 1. The vehicle controller receives the engine water temperature, and uses a two-dimensional lookup table together with the vehicle speed to obtain the fan duty cycle required for engine cooling;

[0043] 2. The vehicle controller receives the water temperature of the motor controller, and uses the two-dimensional lookup table together with the vehicle speed to obtain the fan duty cycle required for motor cooling;

[0044] 3. The vehicle controller receives the gearbox oil temperature, and uses the two-dimensional lookup table together with the vehicle speed to obtain the fan duty cycle required for gearbox cooling;

[0045] 4. The vehicle controller receives the transmission oil temperature, and uses a two-dimensional lookup table together with the vehicle speed to obtain the fan duty cy...

Abstract

The invention relates to a control method of a heat management system of a hybrid electric vehicle. According to the method, the heat dissipation, the refrigeration and the heating of a whole vehicle are integrally controlled by using a whole-vehicle controller. The control method comprises the following steps: receiving feedback parameters by using the whole-vehicle controller; calculating the received feedback parameters; and outputting control parameters.

Description

technical field [0001] The invention relates to a control method for a complete vehicle of a hybrid electric vehicle, in particular to a control method for a thermal management system of a complete vehicle of a hybrid electric vehicle. Background technique [0002] The following technical problems exist in the prior art: the traditional manual air-conditioning control panel has obvious disadvantages in coordinating the high-voltage battery energy and the controller of the air-conditioning system, the automatic air-conditioning panel is expensive, and its own lack of experience in controlling the air-conditioning components of the high-voltage system cannot Fully combining the status of each component of the system for integrated control increases the cost of the controller and is limited to the impact of the automatic / manual air conditioning panel. Contents of the invention [0003] The purpose of the present invention is to provide a control method for the vehicle thermal...
