Engine self-adaptive system based on vehicle operation conditions

The invention discloses an engine self-adaptive system based on vehicle operation conditions, which comprises a GPS (global positioning system) navigation module, a vehicle operating data acquisition module, a whole vehicle parameter and engine working condition data storage module, a map data storage module, a data operation module, a decision-making module and a vehicle control module. The data operation module calculates a current operating state parameter of the vehicle according to vehicle operating data acquired by the vehicle operating data acquisition module and vehicle configuration parameters in the engine working condition data storage module; and then the decision-making module judges the whole vehicle dynamic requirement according to the current operating state parameter of the vehicle and the current section road information, and then acquires the corresponding engine operation parameter in the whole vehicle parameter and engine working condition data storage module, and execution is performed by the vehicle control module. According to the engine self-adaptive system based on the vehicle operation conditions, fuel saving efficacy is achieved through reasonable control of output characteristics of the engine under the premise of guarantee of vehicle dynamic property.
