Embodiment Construction

[0045] The invention provides an evaluation system for fuel-saving driving. The system includes a waste fuel volume (wasteful fuel consumption caused by driving habits) calculation unit. The waste oil amount calculation unit is embedded in the engine control unit, and the waste oil amount calculation unit includes an information storage unit, a deceleration waste oil amount calculation unit, and a waste oil amount processing and storage unit. The waste oil calculation unit obtains the required information from the storage unit of the engine control unit and stores it in the information storage unit, including: vehicle speed, engine speed, accelerator pedal opening, instantaneous fuel consumption, instantaneous driving distance, calibrated sliding distance map, etc. . The deceleration waste oil amount calculation unit acquires information from the information storage unit to calculate the waste oil amount during each deceleration process, and the calculated waste oil amount in...

Abstract

The invention discloses a fuel-saving driving evaluation system for acceleration and deceleration processes and an algorithm. The fuel-saving driving evaluation system comprises a waste fuel quantity computing unit, the waste fuel quantity computing unit is implanted into an engine control unit and consists of a signal storage unit, a deceleration waste fuel quantity computing unit and a waste fuel quantity processing and storage unit, the signal storage unit is connected to the deceleration waste fuel quantity computing unit, the deceleration waste fuel quantity computing unit is connected to the waste fuel quantity processing and storage unit, the waste fuel quantity computing unit acquires required information from a storage unit of the engine control unit and stores the required information in the information storage unit, the deceleration waste fuel quantity computing unit acquires information from the information storage unit and computes waste fuel quantity of each deceleration process, waste fuel quantity information which is obtained via computation is inputted into the waste fuel quantity processing and storage unit, and the waste fuel quantity processing and storage unit computes the total waste fuel quantity of deceleration processes. By the aid of the fuel-saving driving evaluation system and the algorithm, the waste fuel quantity in the acceleration and deceleration processes of a vehicle can be computed accurately.

Description

technical field [0001] The invention belongs to the field of automobile electronic control, relates to a fuel-saving driving evaluation system for acceleration and deceleration processes, and provides a fuel-saving driving evaluation algorithm for acceleration and deceleration engineering. Background technique [0002] At present, the world is facing an energy and environmental crisis, and automobile fuel consumption and emissions are major factors that cause energy and environmental problems. A large part of modern automobile technology focuses on how to save fuel and reduce emissions, and has achieved good results. However, the driver is also an important factor affecting the fuel consumption of the vehicle. If the driver's operating habits are not good, then the technically fuel-efficient car may not be fuel-efficient. This paper provides a fuel-saving driving evaluation system and a fuel-saving driving evaluation algorithm for the driver's operating habits during acceler...
