A method for automatic optimization of driving behavior

Abstract

The invention relates to an automatic driving behavior optimizing method which can judge bad driving behaviors. The bad driving behaviors comprise at least one of high-speed driving at a low gear, abrupt acceleration and unsteady stepping on an accelerator, and corresponding control algorithms are adopted to relieve the bad driving behaviors: when the driving behavior of high-speed driving at a low gear occurs, the highest rotation speed of an engine of a vehicle is limited to be at a preset highest rotation speed value; when the behavior of abrupt acceleration occurs, an actual accelerator pedal value is limited, and an output accelerator pedal value is acquired and does not exceed the actual accelerator pedal value under a normal driving condition; when the behavior of unsteady stepping on the accelerator occurs, the engine is controlled to output a power value according to an engine torque value corresponding to a set accelerator pedal value. According to the method, power output of the engine is directly controlled, active correction and optimization are performed when a driver has a bad driving behavior, the bad driving problem is fundamentally solved, and the driving safety and the fuel conservation effect are improved.

Description

technical field [0001] The invention relates to the field of automotive electronic control, in particular to a method and system for optimizing driving behavior with significant fuel-saving effects. Background technique [0002] According to our statistics and analysis of a large number of passenger car operating data, we have tracked and interviewed tens of thousands of drivers, and found that there are generally bad driving behaviors such as rapid acceleration, sudden ups and downs of the accelerator, low gear and high speed. These driving behaviors will have a certain negative impact on driving safety, vehicle accessories, fuel consumption, etc. Among them, stepping on the accelerator pedal quickly and deeply in a short period of time will not only greatly increase fuel consumption, but also cause energy waste. and environmental pollution, and there are serious safety hazards; the driving behavior of the accelerator pedal fluctuating up and down during driving will cause ...

Problems solved by technology

[0004] The present invention provides a driving behavior automatic optimization method to solve the problem in the prior art that only the driver is reminded after bad driving behavior is judged, and the fuel-saving effect cannot be achieved when the driver ignores these reminders
