The probability that accident occurs, and then under the premise of meeting driver's driving intention and vehicle operates normally, reach farthest
The purpose of energy saving, highly effective and safe is run, while laying the foundation for the efficient operation Theoretical Design of intelligent vehicle, have important
Scientific meaning and theoretical value.
A kind of vehicle efficient operation speed optimization method proposed by the present invention is as shown in Figure 1, step includes S1: determining driving
Device rotary speed optimized initial value, S2: vehicle real time execution speed, S3: determine current vehicle position to next traffic post distance,
S4: running time, the S5 to next traffic post are calculated: acquiring the remainder with next traffic post traffic signals transformation periodt re, S6:
Does is next traffic post traffic signals? S71: it obtains next traffic post and prevents the right of way signal end timet R, S72: obtain next friendship
The logical hilllock right of way signal end timet G, S81:t re > t RS82:t re < t GCurrent vehicle speed is kept with S9.
The rotational speed of driving unit optimized initial value of step S1 is true by the efficient revolving speed section of driver intention and driving device
It is fixed；Step S3, S5, S6, S71 and S72 are related to the data such as onboard navigation system and traffic signals management system；Step S71's
Preventing right of way signal includes the red light and steady yellow on travel route；Step S2 becomes by adjusting rotational speed of driving unit or transformation
Fast case gear is realized；Adjusting the corresponding rotational speed of driving unit of the step S2 need to be in driving device efficient operation revolving speed section.
Whether vehicle drive unit revolving speed is in the traveling economy that efficient operation section directly affects vehicle, of the invention
Vehicle efficient operation speed optimization method comprehensively considers vehicle on the basis of considering driver intention and running conditions of vehicle
Current location obtains that optimal or preferably vehicle runs vehicle away from the factors such as next traffic post distance and traffic lights transformation periods
Speed reminds driver to correct operation reserve, the vehicle drive unit revolving speed time as much as possible is made to be in efficient operation area in time
In, the economy of vehicle operation can be largely promoted, and have the function of reducing traffic accident probability of happening.
A kind of vehicle efficient operation speed optimization method of the invention is suitable for technical field of vehicle control, especially applies
In pure electric automobile technical field, the course continuation mileage number of vehicle will be effectively increased；It and is the safe operation of vehicle and intelligent vapour
The efficient operation of vehicle has established preferable theoretical basis.After vehicle efficient operation speed optimization method practical application of the invention,
Driving device energy consumption will be largely reduced, and then brings biggish economic benefit.
Detailed description of the invention
Fig. 1 is a kind of vehicle efficient operation speed optimization method figure of the invention.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Figure 1, a kind of vehicle efficient operation speed optimization method proposed by the present invention, step includes: S1: being determined
Rotational speed of driving unit optimized initial value, S2: vehicle real time execution speed, S3: determine current vehicle position to next traffic post away from
From, S4: calculating running time, the S5 to next traffic post: acquiring the remainder with next traffic post traffic signals transformation periodt re、
Does is S6: next traffic post traffic signals? S71: it obtains next traffic post and prevents the right of way signal end timet R, S72: obtain it is next
The traffic post right of way signal end timet G, S81:t re > t RS82:t re < t GCurrent vehicle speed is kept with S9.
A further preferred embodiment of the present invention is:
