Description
Technical field
The present invention relates to automotive field of speeding, more particularly, relate to one and have power-steering with automobile of speeding.
Background technology
Automobile since being born at the end of last century, more than 100 year of trials and hardships of having passed by.Step into 21 century, along with development and the growth in the living standard of science and technology, people require more and more higher to the safety of automobile and traveling comfort, various pioneering technology, as intelligent transportation system (ITS), automobile active safety technology (ABS, ASR), automatic driving technology (Automated Drive), vehicle cruise technology AMT etc. are employed and study, auto-industry are welcome again new challenge and revolution.When automobile is convoy on single track with speeding, rear car follows the motoring condition of front truck, and namely front truck and rear car reach information communication, and rear car is according to the information of front truck, car parameter differences before and after contrast, is scaled rear car and drives scheme and realize automatic Pilot.Universal rapidly along with the sustainable development of world economy and automobile, traffic congestion becomes an international difficult problem, and automobile well can be alleviated with the technology of speeding and even addresses this problem.
Existing with automobile of speeding, it utilizes automatic Pilot control analysis system to control auto-steering module, but, when vehicle is when turning to, its application force needed is large, namely needs auto-steering module to provide very large application force to make with motor turning of speeding, especially when turning to greatly the speed of a motor vehicle low, need the very large power of output could export larger power-assisted to make, with motor turning of speeding, to waste resource to a certain extent.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of with automobile of speeding, and it has servo-steering function, and economize energy reduces cost.
The present invention's adopted technical scheme that solves the problem is:
One has power-steering with automobile of speeding, comprise and the behavior control device with automobile of speeding is carried out manipulating the automatic Pilot control analysis system realizing driving with speeding and the situation control setup manipulated by automatic Pilot control analysis system, described automatic Pilot control analysis system is connected with servo steering system.
As preferably, described servo steering system is steering shaft booster type system.
Further, described servo steering system comprises steering gear, the steering shaft be connected on steering gear, the driving engine be connected on steering shaft, and described driving engine is connected on ECU, and described ECU is connected with automatic Pilot control analysis system.
Further, described steering shaft is provided with torque sensor, speed reduction gearing, described torque sensor is connected on ECU.ECU is the abbreviation of Electronic Control Unit, i.e. electronic control unit, is then automobile specified microcomputerized controller, is also automobile specified micro controller system from purposes.According to the program of its internal memory and data, computing, process, judgement are carried out, then output command to the information that charge air takes into account the input of various sensor, provide the electric impulse signal of one fixed width to control fuel charge to fuel injector.
Steering shaft is a part for situation control setup, automatic Pilot control analysis system is when handling steering shaft and turning to, automatic Pilot control analysis system turning to steering shaft and the size of torque, voltage signal is transported to electronic control unit, electronic control unit is according to torque voltage signal, rotation direction and vehicle speed signal etc., send instruction to engine controller, make driving engine export the power steering torque of corresponding size and Orientation, thus produce auxiliary power.When automobile does not turn to, electronic control unit does not send instruction to engine controller, and driving engine does not work.
As preferably, described situation control setup comprises clutch, brake, throttle and steering indicating light.
To sum up, the invention has the beneficial effects as follows:
The present invention sets up servo steering system existing with in the automatic Pilot control analysis system of automobile of speeding, and solves steering power and exports large problem, saved the energy, reduced cost.
