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...

Problems solved by technology

[0009] The above two schemes judge the fuel-saving performance of the driver’s operation during the acceleration and deceleration process by the distance traveled by the vehicle, which cannot allow the driver to intuitively understand how much fuel is consumed by his operation; in addition, during the acceleration process, Judging whether the operation is fuel-efficient or not only by the opening of the accelerator pedal at a certain speed is not accurate
