Abstract

The invention discloses an engine self-adaptation system based on a vehicle operation condition and an oil-saving method. The engine self-adaptation system comprises an information center and a plurality of vehicle terminals which are in communication connection with the information center, wherein each vehicle terminal comprises a GPS (global position system) navigation module, a vehicle operation data collection module, a vehicle parameter and engine operation condition data storage module, a wireless communication module, a data operation module, a decision-making module and a vehicle control module; and the information center comprises a wireless communication module, a map data storage module, a historical data storage module and a route optimization data storage module. According to the engine self-adaptation system and the oil-saving method, the vehicle control module adjusts response characteristics of an engine and reduces maloperations of an accelerator; besides, a standard road resistance characteristic coefficient is an optimized value, so that higher reference is provided, and on the premise that the vehicle power is guaranteed, output characteristics of the engine are controlled reasonably, and the effect of saving oil saving is realized.

Description

technical field

[0001] The present invention relates to the field of vehicle engine control, and more specifically relates to an engine self-adaptive system and a fuel-saving method based on vehicle operating conditions. The effect of vehicle fuel consumption. Background technique

[0002] According to the dynamic response characteristics of the engine, when the throttle shows a steady change, the dynamic relationship between the engine torque and the speed is close to linear, and its curve is a curve that lags behind the change of the throttle; when the throttle shows a step change, the engine output The torque increases instantaneously, and the fuel injection volume of the engine suddenly increases with the change of the throttle. Since the engine speed and the supercharging system rise steadily, it cannot keep up with the change of the fuel injection volume. The test data shows that: under 100% throttle step, the air mixture in the cylinder is too rich within about 5 sec...
