Engine control system, engine control system control method and passenger car

Abstract

The invention relates to the technical field of automobile manufacturing, and discloses an engine control system, an engine control system control method and a passenger car. The engine control system comprises a first cooling circulation loop, a second cooling circulation loop, a warm air loop, a first throttling valve, a second throttling valve, a detection module and a control module. The detection module can detect temperature information of an engine and environment temperature information in real time, and the control module can control opening, closing and the opening degree of the first throttling valve and the second throttling valve according to the information detected by the detection module. And the controller is used for controlling the flow of the cooling liquid in the first cooling circulation loop, controlling the warm air loop to be conducted through the first branch or the second branch and controlling the flow of the cooling liquid in the warm air loop. Comprehensive control over the engine and the warm air system is achieved, rapid engine heating of the engine and rapid defrosting of the windshield can be achieved in the cold environment, the temperature rising speed in the vehicle is increased, the vehicle preheating time is shortened, energy consumption is low, and economic practicability is better.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an engine control system, a control method of the engine control system and a passenger car. Background technique [0002] At present, in the cold environment of large and medium-sized passenger cars, the engine usually needs to be heated, and a heating system is generally designed. Traditional large and medium-sized passenger cars use a water heating system. The specific plan is to use a set of heating components and engine cooling. System circulation loop, heater components include heater fuel heater, defroster, interior radiator, heater multi-connection control switch, water heating pipe and mechanical opening and closing valve, etc. The circulation loop of engine cooling system includes engine, integrated thermal management Functional vehicle radiator, connecting water pipes, etc. The heater assembly is connected in parallel with the circulation loop of the ...
