Automobile control system, method and automobile

Abstract

The invention relates to an automobile control system, which comprises a gasoline supply device, a methanol supply device and a fuel supply control system, wherein the fuel supply control device comprises a monitoring unit and an electronic control unit; the monitoring unit monitors the water temperature of an engine and sends the temperature to the electronic control unit; the electronic controlunit sends a control command to the methanol supply device when judging that the water temperature exceeds the preset temperature, and the methanol supply device supplies methanol to the engine; and contrarily, the electronic control unit sends the control command to the gasoline supply device which supplies gasoline to the engine. An automobile control method comprises the following steps: monitoring the water temperature of the engine; when the water temperature exceeds the preset temperature, controlling the methanol supply device to supply the methanol to the engine; and contrarily, controlling the gasoline supply device to supply the gasoline to the engine. The system and the method solve the problems of difficult low-temperature starting, poor cooler discharge and methanol-gasoline mixed fuel demixing caused by using methanol or the methanol-gasoline mixed fuel in an automobile in the prior art.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an automobile control system, method and automobile. Background technique [0002] Methanol is a new alternative energy source for vehicles. Due to the wide range of raw materials for methanol production, the transportation, storage, filling and use of products are similar to gasoline and diesel fuel for internal combustion engines on the market; and methanol has a high octane number and its own Oxygen-containing combustion is complete, the ignition temperature is higher than that of gasoline, and the combustion process is safe; therefore, methanol has become the most realistic and ideal vehicle alternative fuel in the post-petroleum era. [0003] At present, there are two main ways to use methanol fuel in automobiles: the first is to pre-mix methanol and gasoline into a mixed fuel in a certain proportion, and the car directly uses this mixed fuel to make the engine do...
