When member's steering wheel rotation 11, the rotation of steering wheel 11 sends steering gear 12 to by jackshaft 10.Steering 1 further includes turning left
To section 14, the revolver (not shown) for the vehicle being connect with left steering section 14, right turn section 16 and the vehicle being connect with right turn section 16
Right wheel (not shown).As shown in Fig. 2, steering gear 12 includes gear 120 and rack 124.During the rotation of steering wheel 11 passes through
Countershaft 10 sends gear 120 to.Rack 124 and gear 120 are ratcheting.The rotation of gear 120 can then be moved with carry-over bar 124 along straight line
It is dynamic.The linear movement of rack is respectively transmitted by left steering section 14 and right turn section 16 to the revolver and right wheel of vehicle.
Fig. 3 is the block diagram of centering detection device according to an embodiment of the invention.As shown in figure 3, centering detection device 3 is wrapped
It includes：Coordination unit 32 couples order really with the first measuring unit 34 of the coupling of coordination unit 32 and with the first measuring unit 34
Member 36.First detection unit 34 is matched with coordination unit 32, to measure the first value of the steering angle of instruction wheel.
Fig. 4 is the left view of the critical piece of steering shown in Figure 2.As shown in figure 4, steering 1 further includes
Coordinator 126 on rack 124, and the detector 122 on gear 120.In conjunction with Fig. 3 and Fig. 4, coordination unit 32
Such as it is fixed on the coordinator 126 on rack 124.First detection unit 34 is for example fixed on the detection on gear 120
On device 122.First detection unit 34 is matched with coordination unit 32, detects the movement of rack 124.Due to gear 120 and centre
Axis 10 connects, it is possible to according to the straight-line displacement for the rack 124 that first detection unit 34 is detected, to obtain corresponding wheel
Steering angle.
Centering detection device 3 can also include second detection unit 38.The steering wheel 11 of second detection unit and vehicle and
Determination unit 36 is connected.The steering angle of 38 measurement direction disk 11 of second detection unit, and using the steering angle as second
Value sends determination unit 36 to.Second detection unit 38 is, for example, angular transducer.
In steering 1, determination unit 36 can be located at any suitable position.For example, positioned at the outer of steering gear 12
Portion or the inside of steering gear 12.The steering wheel of the first value and instruction vehicle of steering angle of the determination unit 36 based on instruction wheel
Steering angle second value, come determine vehicle steering gear 12 whether centering.Here, refer in 12 pairs of steering gear：Work as vehicle
When driving, steering wheel is placed in the middle for normal straight, and the gear of steering gear is located at the midpoint of rack, the i.e. gear 120 and tooth of steering gear 12
Item 124 is ratcheting in middle position.
In a specific example, first detection unit 34 is Hall sensor, and coordination unit 32 is magnet.For example, magnetic
The excessively special glue of Tie Tong is fixed on the back of the rack 124 of turning machine 12, to ensure with rack 124 without relative motion.Hall passes
Sensor is connected by a snap on the shell for the gear 120 for being fixed on turning machine 12, to ensure that the position of the sensor will not move.
When 12 centering of steering gear, i.e. for gear 120 when the midpoint on rack 124 is ratcheting, magnet is located at the underface of Hall sensor.
In another specific example, magnet can be fixed on rack, and Hall sensor can be fixed on the shell of rack.Work as steering
When 12 centering of device, magnet is located at immediately below Hall sensor.Certainly, the realization method of first detection unit 34 and coordination unit 32
It is without being limited thereto with position.For example, first detection unit 34 and coordination unit 32 can also be embodied as infrared inductor and with it is infrared
Corresponding coordinator of inductor etc..Correspondingly, first detection unit 34 and coordination unit 32 can be according to their specific implementations
Mode is located at any suitable position in steering gear 12.
Determination unit 36 can be according to the steering of the first value and the steering wheel of instruction vehicle of the steering angle of instruction wheel
The second value of angle whether at predetermined ratio come judge steering gear 12 whether centering.When the first value is proportional to second value, really
Order member 36 judges 12 centering of turning machine.When the first value does not make a reservation for proportional to second value, determination unit 36 judges steering gear
12 misalign.Here, it can be equal at predetermined ratio, can also be into predetermined ratio.For example, the first value and second
It is scheduled 0.5 to be worth the equal or ratio of the first value and second value.
Centering detection device 3 can also include alarm unit 39.Alarm unit 39 is coupled with determination unit 36.Alarm is single
Member 39 can be located at any suitable position in vehicle.When determination unit 36 judges that steering gear 12 misaligns, alarm unit 39
Alarm is sent out to driver.For example, beeping to driver, or instruction failure is shown on the instrument disc assembly of vehicle
Alarm.Certainly, which can also be presented in another suitable way.
When steering gear 12 does not have centering, determination unit 36 can be further according to the first of the steering angle of instruction wheel
Value and indicate that the deviation of second value of steering angle of the steering wheel of vehicle determines the departure degree of steering gear 12.For example, the
The deviation of the ratio and predetermined ratio of one value and second value is bigger, indicates the bigger with departure degree when centering of steering gear 12.
Can be that first detection unit 34 measures and rack 34 about the first value of the steering angle for obtaining instruction wheel
The corresponding voltage value of shift value, and the voltage value is converted to the steering angle of corresponding wheel, as the first value.Certainly,
Can also be that the voltage value of measurement is transferred directly to determination unit 36 by the first measuring unit 34, by determination unit 36 by the electricity
Pressure value is converted to the steering angle of corresponding wheel, as the first value.
Fig. 5 shows the correspondence of the displacement of voltage value and rack 34 measured by the first measuring unit 34.For example, working as
Vehicle normal straight travels, and when steering wheel is between two parties and the gear 120 of steering gear 12 is with 124 normal centering of rack, turns at this time
Gear is located at gap width, and the displacement of rack is 0.Output voltage measured by first measuring unit 34 is total null voltage：2.5V.
The voltage value is transferred to determination unit 36 by the first measuring unit 34, which is converted to corresponding instruction by determination unit 36
First value of steering angle of wheel.Meanwhile determination unit 36 reads the steering angle of instruction steering wheel from the second measuring unit 38
Second value.As described above, determination unit 36 can based on first value and second value come judge steering gear 12 whether centering.
