Embodiment Construction

[0024] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0025] The bad driving behaviors in this embodiment include resisting high speed, rapid acceleration and unstable accelerator. Among them, low-gear and high-speed bad driving behavior is defined as: the vehicle gear is in a lower gear, but the engine speed is very high. This behavior cannot keep the vehicle in the optimal speed and speed range, which not only greatly increases fuel consumption, but also Can cause irreparable damage to vehicle accessories. Bad driving behavior of rapid acceleration refers to: stepping on the accelerator pedal quickly or deeply in a short period of time, so that the speed of the vehicle will increase rapidly, which will not only greatly increase fuel consumption, cause energy waste and environmental pollution, but also pose serious safety hazards; Bad driving behavior refers to: the driving behavior of the acc...

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 ...
