Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
Fig. 2 is the structured flowchart of vehicle according to the invention transfer.Vehicle includes steering wheel, steering gear and steer motor, and wherein steer motor provides steering power power-assisted for steering gear.As shown in Figure 2, vehicle steering device 110 provided by the invention may include that direction detector 111, for detecting whether steering wheel is rotated, and controller 112, for when steering wheel is rotated, control steer motor 8 work and think that steering gear provides steering power power-assisted, and when steering wheel is not rotated, control steer motor 8 and quit work.
Fig. 3 is the structure chart of the vehicle steering device according to one embodiment of the present invention.In this embodiment, direction detector 111 is photoelectric encoder, it is to be understood that be not intended to limit the invention to this.Controller 120 is connected between photoelectric encoder and steer motor 8, and the data of photoelectric encoder collection are carried out geometric operation by controller.As it is shown on figure 3, this photoelectric encoder includes photoemitter 11 and optoelectronic induction sheet 10.Wherein, photoemitter 11 can be installed in the steering spindle 3 of vehicle, and optoelectronic induction sheet 10 can be installed on the end face relative with photoemitter of steering column tube 2 of vehicle.And, optoelectronic induction sheet 10 is provided with zero point district, and when steering wheel 1 is not rotated, photoemitter 11 is directed at the zero point district of optoelectronic induction sheet 10, now, controller 120 calculates photoelectric encoder according to the data of the photoelectric encoder collected and is counted as zero.Steering procedure below with reference to the Fig. 3 vehicle to having transfer provided by the present invention is described in detail.
As it is shown on figure 3, walk at its straight line, steering wheel 1 mediates when not rotated, and photoemitter 11 is directed at the zero point district on optoelectronic induction sheet 10, and, the photoelectric encoder that controller 120 calculates is counted as zero.When steering wheel 1 is rotated, if steering wheel 1 is to anticlockwise, then drive steering spindle 3 to anticlockwise, it is simultaneously attached to the photoemitter 11 in steering spindle 3 also therewith to anticlockwise, and the steering column tube 2 owing to being fixed on driver's cabin will not rotate along with the rotation of steering wheel 1, therefore, optoelectronic induction sheet 10 mounted thereto is without rotating with.So, now, being sensed with optoelectronic induction sheet 10 phase by photoemitter 11, controller 120 calculates photoelectric encoder according to the data of the photoelectric encoder now collected and is counted as a positive.If steering wheel 1 is to right rotation, similar with said process, dextrorotary photoemitter 11 senses with non-rotary optoelectronic induction sheet 10 phase therewith, and controller 120 calculates photoelectric encoder according to the data of the photoelectric encoder now collected and is counted as a negative value.Photoelectric encoder sends data to controller 120, the data of photoelectric encoder collection are carried out geometry plus and minus calculation by controller, when the operation values that photoelectric encoder counts is nonzero value by controller 120, controller 120 controls steer motor 8 and runs, to drive steering pump 9 to work, and then provide steering power power-assisted by power cylinder 4 to steering gear 5, thus driving steering arm 6 and wheel 7 to turn to.
Wherein, in this embodiment, when steering wheel 1 is rotated, steer motor 8 drives the steering pump 9 of vehicle to work, the power cylinder 4 of vehicle utilizes the hydraulic fluid pressure that steering pump 9 provides to provide steering power power-assisted for steering gear 5, rotates thus carrying out band motor car wheel 7.
After steering wheel 1 completes to rotate, steering wheel 1 recovers to centre position when not rotating, and now, photoemitter 11 is directed at the zero point district on optoelectronic induction sheet 10, and the photoelectric encoder calculated in controller 120 is counted as zero.Now, to control steer motor 8 out of service for controller 120.Pass through said process, it is capable of when vehicle turns left or turns right, controller 120 controls steer motor 8 operation and drives steering pump 9 to work, to provide steering power power-assisted to steering gear 5, thus band motor car wheel 7 turns to, and when its straight line travels, it is out of service that controller 120 controls steer motor 8.It is thus possible to realize saving the purpose of vehicle electric energy, and then improve the service efficiency of electric energy.
In embodiments of the present invention, the installation site of photoemitter 11 and optoelectronic induction sheet 10 is not limited to above-mentioned installation site, it may be mounted on any suitable position being capable of technical solution of the present invention, such as, alternately, optoelectronic induction sheet 10 can be arranged in steering spindle 3, and photoemitter is arranged on the end face relative with optoelectronic induction sheet 10 of the steering column tube 2 of vehicle.
It addition, the present invention also provides for a kind of vehicle, this vehicle includes above-mentioned vehicle steering device.
And, the present invention also provides for a kind of vehicle steering method, vehicle includes steering wheel 1, steering gear 5 and steer motor 8, wherein steer motor 8 provides steering power power-assisted for steering gear 5, this vehicle steering method includes: whether detection steering wheel 1 is rotated, and when steering wheel 1 is rotated, control steer motor 8 work and think that steering gear 5 provides steering power power-assisted, and when steering wheel 1 is not rotated, control steer motor 8 to quit work, thus realizing saving the purpose of vehicle electric energy, and then improve the service efficiency of electric energy.Wherein, when steering wheel 1 is rotated, steer motor 8 drives the steering pump 9 of vehicle to work, and the power cylinder 4 of vehicle utilizes the hydraulic fluid pressure that steering pump 9 provides to provide steering power power-assisted for steering gear 5.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing; but; the present invention is not limited to the detail in above-mentioned embodiment; in the technology concept of the present invention; technical scheme can being carried out multiple simple variant, these simple variant belong to protection scope of the present invention.
