Abstract

The invention discloses an engine cooling system control device and method and a vehicle. The control device comprises an engine start state obtaining module, a water tank temperature monitoring module, a water tank temperature changing value calculating module and a control module. The engine start state module is used for obtaining the start state of an engine, and the start state of the enginecomprises the engine running variable value. The water tank temperature monitoring module is used for monitoring the real-time temperature of a water tank. The water tank temperature changing value calculating module calculates the temperature change value of the water tank within the calibrated time interval. The control module controls cooling liquid not to flow through the water tank when the running variable value shows that the engine does not run instead of running and the temperature change value of the water tank within the calibrated time interval is smaller than the calibration value. According to the control device of the embodiment, the cold start performance and the emission performance of the vehicle are improved on the premise that additional devices are not added.

Description

technical field [0001] The invention relates to a control device, a control method and a vehicle of an engine cooling system. Background technique [0002] If the warm-up process is too long when the engine is started from a cold engine for a long time, the start-up and emission performance will be deteriorated. The prior art discloses a heating and warming device that adds a regenerative heat exchanger to the exhaust component (catalytic converter) of an automobile, and the device can improve the cold start performance and emission performance of the automobile. But this technology adds extra devices and increases the cost. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, the first object of the present invention is to provide a control device for the engine cooling system, which can improve the cold start performance and emission performance ...
