Embodiment Construction

[0048] Such as figure 1 As shown, a method for fast warming up of an automobile according to the present invention includes: after the vehicle is powered on, the temperature control module performs a self-inspection and detects whether the water temperature sensor is normal, and when the self-inspection is normal and the water temperature sensor is normal, it is judged that the engine is working state and read the current water temperature value; when the engine is in the working state and the current water temperature value is less than the warm-up end threshold, the temperature control module enters the fast warm-up mode; in the fast warm-up mode, the main control parameters are controlled to enter the fast warm-up according to the parameter rules The basic value of the mode, the main control parameters include the duration of each opening in ON-OFF mode, the angular position of each opening and the duration of each closing; obtain the actual heat dissipation situation of the...

Abstract

The invention discloses an automobile rapid warming-up method and system. The method comprises the steps that when an engine is in a working state and a current water temperature value is smaller thana warming-up ending threshold value, a temperature control module enters a rapid warming-up mode; main control parameters are controlled to enter basic values of the rapid warming-up mode according to parameter rules in the rapid warming-up mode; the actual heat dissipation condition of a whole automobile is obtained, a current risk index condition is judged, the main control parameters are adjusted according to the current risk index condition, and the current water temperature value after parameter adjustment is read; and when the engine is in the working state and the current water temperature value is larger than the warming-up ending threshold value, the temperature control module enters a normal working mode. The invention provides the rapid warming-up method capable of actively controlling the warming-up process, the warming-up can be further accelerated, and the problem that the active control on the warming-up process cannot be simultaneously realized while rapid warming-up is ensured in an existing warming-up method is solved.

Description

technical field [0001] The invention relates to the field of temperature control of automobile engines, in particular to a method and system for rapid warming up of automobiles. Background technique [0002] The cooling system of the automobile engine is to ensure that the engine works at the most suitable temperature through temperature adjustment. At present, the cooling system of the whole vehicle on the market usually uses a mechanical water pump and a thermostat. The physical structure of the thermostat is mainly based on the wax bag. When the water temperature is low, the wax bag is solid, the spring is restricted, and the branch of the coolant leading to the radiator is closed. When the water temperature is too high, the wax bag melts, and the spring acts to open the heat dissipation Cool down the branch circuit. This structure determines that the engine cooling system can only switch between the large cycle (radiator participates) and small cycle (radiator does not ...
