Information, traffic lights information and traffic mark information can truly obtain present road environmental aspect, so as to subsequently to traveling
The selection of pattern is more accurate.
In the prior art, the identification of road condition judges average speed and idling mode typically merely by vehicle, this reality
A step S3 is applied to be expanded as to city operating mode, suburb operating mode and high-speed working condition are further segmented.According to vehicle electric
The speed signal that constancy system ESP is provided calculates vehicle average speed, and the vehicle provided according to engine management system EMS is idle
Fast status signal calculates dead time ratio（I.e. dead time accounts for the ratio of total time）, then according to average speed and idling when
Between ratio, respectively to city operating mode, suburb operating mode and high-speed working condition are further segmented, referring specifically to following table：
Similarly, for judgement also each own judgment threshold of average speed and dead time ratio, concrete numerical value root
It is specifically defined according to the result of the traffic behavior statistics of current countries and regions.For example, under the operating mode of city, it is assumed that 80% is idle
The threshold value of fast time scale "high", 20 kilometers/hour of threshold values for average speed " low ", then when the current idling of calculated vehicle
Time scale is higher than 80% and average speed is less than 20 kilometers/hour, then is determined as the road way operating mode that vehicle is presently in
" congestion prosperity operating mode ".For another example, it is assumed that 20% and 80% be respectively dead time ratio " in " threshold value, 20 kilometers/hour and 50
Kilometer/hour be respectively average speed " in " threshold value, then when the current dead time ratio of calculated vehicle be in 20% ~ 80%
Between, and average speed less than 50 kilometers/hour but is higher than 20 kilometers/hour, then the road way work being presently in vehicle
Condition is determined as " Xincheng District operating mode ".
It obtains residing for vehicle after real roads situation through the above steps, then selects corresponding driving mode accordingly, it can be with
Preferably vehicle energy is managed, obtains more preferably fuel economy.
