Member, wherein：Effec-tive Function speed optimization calculation unit receives angular acceleration transducer, speed probe, traffic signals management system
The live signal of system, running conditions of vehicle decision-making system and onboard navigation system, and the real-time high-efficiency fortune being calculated will be optimized
Driving speed is transmitted to vehicle ECU；Angular acceleration transducer is connected with vehicle accelerator pedal；Speed probe and vehicle drive unit
Output shaft is connected.
Angular acceleration transducer and speed probe are hall sensor；Speed probe exports with vehicle drive unit
Axle is electrically connected；Traffic signals management system is synchronous with the traffic signals management system of Department of Communications；Running conditions of vehicle judges system
The vehicle driving-cycle that system judges includes vehicle suddenly acceleration, anxious deceleration, upward slope, descending, straight road traveling, and city road
Condition, high-speed road conditions and road conditions of jolting etc.；Effec-tive Function speed optimization calculation unit is built-in with the efficient rotating speed area of vehicle drive unit
Between MAP.
Whether vehicle drive unit rotating speed directly affects the traveling economy of vehicle in Effec-tive Function section, of the invention
Vehicle Effec-tive Function speed obtains system, on the basis of driver intention and running conditions of vehicle is considered, considers vehicle
Away from the factor such as next traffic post distance and traffic lights transformation periods, vehicle real-time high-efficiency fortune is calculated in optimization for current location
Driving speed, reminds driver to correct operation reserve, the vehicle drive unit rotating speed time as much as possible is in efficient fortune in time
In row section, the economy of vehicle operation can be largely lifted, and has the function that to reduce traffic accident probability of happening.
A kind of vehicle Effec-tive Function speed of the present invention obtains system and is applied to automobile technical field, particularly applies pure
During electric vehicle engineering field, the course continuation mileage number of vehicle will be effectively increased；And it is safe operation and the intelligent automobile of vehicle
Effec-tive Function has established preferable theoretical foundation., will after the vehicle Effec-tive Function speed of the present invention obtains system industryization application
Bring larger economic benefit.
