As shown in figure 22, in rolling control, carry out following processing.Promptly, if tilt the deviation of the detected value of angle transducer 123 and the signal value at the angle that tilts corresponding to target in the dead band of rolling control usefulness to the left bank lateral deviation of body main body V from (step 11,12), carry out that then the attitude that tilts of body main body V is handled to the right bank of right-hand descent direction attitude change.Promptly, detection information based on the stroke sensor 120,121 of the front and back that are positioned at the body right side, certain that judges whether right front cylinder 104 and right back cylinder C5 is operated into the lower position, if two cylinder C4, C5 are not operated into the lower position, then before certain reaches the lower position, make right front cylinder 104 elongation actions and make right back cylinder C5 (step 13,14) under reach.If certain of right front cylinder 104 and right back cylinder C5 is operated into the lower position, then follow detection information based on the stroke sensor 118,119 of the front and back that are positioned at the body left side, certain that judges whether left front cylinder C2 and left back cylinder C3 is operated into upper limit position, if two cylinder C2, C3 are not operated into the lower position, then before certain arrives upper limit position, make left front cylinder C2 under reach and make left back cylinder C3 elongation action (step 15,16).
If the detected value of the above-mentioned angle transducer 123 that tilts and above-mentioned target tilt the deviation at angle in the dead band of rolling control to the right bank lateral deviation of body main body V from, carry out that then the attitude that tilts of body main body V is handled to the left bank of left descent direction attitude change.Promptly, detection information based on the stroke sensor 118,120 of the front and back that are positioned at body left side, certain that judges whether left front cylinder C2 and left back cylinder C3 is operated into the lower position, if two cylinder C2, C3 are not operated into the lower position, then before certain reaches the lower position, make left front cylinder C2 elongation action and make left back cylinder C3 (step 17,18) under reach.If certain of left front cylinder C2 and left back cylinder C3 is operated into the lower position, then follow detection information based on the stroke sensor 119,121 of the front and back that are positioned at the body right side, certain that judges whether right front cylinder C4 and right back cylinder C5 is operated into upper limit position, if two cylinder C4, C5 are not operated into upper limit position, then before certain arrives upper limit position, make right front cylinder C4 under reach and make right back cylinder C5 elongation action (step 19,20).The deviation at angle is in the dead band of rolling control if the detected value of the above-mentioned angle transducer 23 that tilts and above-mentioned target tilt, and then stops the action (step 21) of cylinder.
As shown in figure 23, in pitching control, if the detected value that tilts forward and back angle transducer 124 with corresponding to the deviation of the signal value of level in the dead band of pitching control usefulness to the top rake lateral deviation of body main body V from (step 31,32), then judge to carry out and make 100 actions of attitude alter operation mechanism with the tilt fore and aft of the body main body V attitude corrective action of canting change forward in last time, be left back cylinder C3 of executable operations and right back cylinder C5 and make the back vertical motion that rises on the rear portion of body main body V, perhaps operate left front cylinder C2 and right front cylinder C4 and make at least after any of preceding down maneuver that the front portion of body main body V descends, the body main body V setpoint distance (20cm) (step 33) that whether travelled.
And, if in step 33, after carrying out above-mentioned attitude corrective action, travelled setpoint distance, then move to step 34 then, carry out rear down maneuver and the place ahead vertical motion so that the attitude canting attitude backward that tilts forward and back of body main body V changes.Promptly, based on be positioned at After-Body about the detection information of stroke sensor 119,121, certain that judges whether left back cylinder C3 and right back cylinder C5 is operated into the lower position, if two cylinder C3, C5 are not operated into the lower position, then before certain of this two cylinder C3, C5 reaches the lower position, make left back cylinder C3 and right back cylinder C5 (rear down maneuver) under reach ( step 34,35).If certain of left back cylinder C3 and right back cylinder C5 is operated into the lower position, then before certain of left front cylinder C2 and right front cylinder C4 reaches upper limit position, make left front cylinder C2 and right front cylinder C4 (the place ahead vertical motion) under reach (step 36,37).
If in step 33, judge the setpoint distance that after execution makes 100 actions of attitude alter operation mechanism with the tilt fore and aft attitude corrective action that canting is changed forward with body main body V, do not travel, then get back to step 1, do not carry out make body main body V tilt forward and back angle and the operation of changing in the opposite direction based on the change side of above-mentioned attitude corrective action, which of promptly above-mentioned rear down maneuver and the vertical motion of above-mentioned the place ahead do not carried out.
If the detected value that tilts forward and back angle transducer 124 with corresponding to the deviation of the signal value of level in the dead band of pitching control usefulness to the rear-inclined lateral deviation of body main body V from, then judge to have carried out to make 100 actions of attitude alter operation mechanism with the tilt fore and aft of body main body V attitude corrective action, the some at least backs, the body main body V that have promptly carried out rear down maneuver or the place ahead vertical motion of the canting change setpoint distance (20cm) (step 38) that whether travelled backward in last time.
And, if in step 38, after carrying out above-mentioned attitude corrective action, travelled setpoint distance, then move to step 39 then, carry out the place ahead down maneuver and rear vertical motion, so that the change of the tilt fore and aft canting attitude forward of body main body V.Promptly, based on be positioned at front part of a body about the detection information of stroke sensor 118,120, certain that judges whether left front cylinder C2 and right front cylinder C4 is operated into the lower position, if two cylinder C2, C4 are not operated into the lower position, then before certain of two cylinder C2, C4 reaches the lower position, make left front cylinder C2 and right front cylinder C4 elongation action (the place ahead down maneuver) (step 39,40).If certain of left front cylinder C2 and right front cylinder C4 is operated into the lower position, then before certain arrival upper limit position of left back cylinder C3 and right back cylinder C5, make left back cylinder C3 and right back cylinder C5 elongation action (rear vertical motion) (step 41,42).If the detected value that tilts forward and back angle transducer 124 is in the dead band of pitching control usefulness with deviation corresponding to the signal value of level, then stop the action (step 43) of cylinder.
If in step 40, be judged as the setpoint distance that after execution makes 100 actions of attitude alter operation mechanism with the tilt fore and aft attitude corrective action that canting is changed backward with body main body V, do not travel, then get back in the step 1, do not carry out make body main body V tilt forward and back angle and operation based on the change of the change direction rightabout of above-mentioned attitude corrective action, which of promptly above-mentioned the place ahead down maneuver and the vertical motion of above-mentioned rear do not carried out.
Like this, in the time of when the corrective action of canting attitude forward and during the corrective action of canting attitude backward which, before the setpoint distance that travels, do not carry out attitude corrective action round about, carried out in travelling the tilt fore and aft of body main body backward during the attitude corrective action of canting change so advance in the body main body, to after judge that the body main body travelled before the setpoint distance not the inclination angle canting change forward of body main body, retreat in the body main body and to have carried out in travelling the tilt fore and aft of body main body forward during the attitude corrective action of canting change, to after judge the body main body travelled setpoint distance before not with the inclination angle of body main body backward canting change.
That is,, the structure of following formation is arranged as the structure in the past of attitude-control device.
Promptly, above-mentioned attitude alter operation mechanism possesses respectively change freely and regulates the height of the front portion of body main body with respect to the grounding parts of mobile devices, with the rear portion of body main body with respect to a pair of driving mechanism of the height of the grounding parts of mobile devices and constitute, above-mentioned attitude coutrol mechanism constitutes, if in above-mentioned pitching control, detected the body main body with respect to the level reference oblique situation of inclination that turns forward, then the skidding that marches forward to the body main body from this moment finish setpoint distance during, do not make that the driving mechanism to the effect of body body front part drives to the uplifted side of body body front part in the above-mentioned a pair of driving mechanism.
Above-mentioned mechanism in the past can avoid entering into the following fault that situation on the field etc. takes place when smooth ground enters into the sloping floor etc. like that from ridge for example as shown in figure 24.
Promptly, when when smooth ground enters into the sloping floor, the center of gravity G of body main body V moves to than the initial end of sloping floor and leans on the direct of travel front side, body main body V becomes the place ahead decline lateral attitude (with reference to Figure 24 (b)) sharp, the rear portion side that becomes mobile devices is floated such state from ground, make attitude alter operation mechanism action this moment, becomes the target inclination angle so that body main body V departs from from the target inclination angle from the side that turns forward with respect to the tilt fore and aft of level reference.At this moment, if the direction that the driving mechanism that makes toe lateral rises to the front portion that makes body main body V drives operation, then the center of gravity G of organism main body V move to than the initial end of sloping floor by the rear portion side ground connection of direct of travel rear side, mobile devices on the ground, the toe lateral of mobile devices float, become from ground body main body V with respect to the tilt fore and aft of level reference recede from the target inclination angle lateral deviation from the situation (with reference to Figure 24 (c)) of state.Like this, by carrying out above-mentioned pitching control round about, the initial end that has once more the center of gravity of body main body to cross the sloping floor moves to the situation that body front side, body main body become the place ahead decline lateral attitude.And, this moment, travel speed was set at low speed, if in the variation that attitude is arranged when sloping floor as described above enters, then the driver considers safety and makes the situation about stopping of travelling more, if so under the halted state of travelling, carry out pitching control as described above, then the center of gravity G by body main body V moves forward and backward with respect to the initial end of sloping floor, have the tilt fore and aft that carries out body main body V repeatedly recede from the target inclination angle lateral deviation from state (with reference to Figure 24 (c)), and the tilt fore and aft of body main body V from the target inclination angle turn forward lateral deviation from state (with reference to Figure 24 (d)) between rapid attitude situation about changing.
So, for not taking place, so rapid attitude that moves that is accompanied by center of gravity changes, in the past, if detect the body main body with respect to the tilt fore and aft of level reference turn forward from the target inclination angle lateral deviation from situation, then the skidding that marches forward to the body main body from this moment sailed setpoint distance during, the direction that the toe lateral driving mechanism is risen to the front portion that makes the body main body drives operation, avoids the rapid attitude that moves that is accompanied by center of gravity as described above to change.
But, in above-mentioned structure in the past, shown in Figure 24 (b), entering into the situation that sloping floor phosphor bodies on opportunity becomes the place ahead decline lateral attitude sharp from smooth ground even have, owing to do not make the action of the tilt fore and aft canting attitude backward change of body main body this moment, so continue to travel under the state of the lateral attitude that descends forwardly.Like this, if if sloping floor as described above along the width of direct of travel short advance slightly travel then the body main body after horse back enter into the ground situation in smooth field, also continue to travel with the original state of the place ahead decline lateral attitude if then become the place ahead decline lateral attitude, then the leading section of body main body might contact at the field face first-class.In addition, although become the place ahead decline lateral attitude entering into sloping floor phosphor bodies on opportunity from smooth ground, do not make the tilt fore and aft canting attitude backward change of body main body yet,, be difficult to carry out the disadvantageous aspect of driver behavior etc. in addition so that the driver's who takes attitude becomes is unstable.
On the other hand, the attitude-control device of the invention described above is to possess the body main body with respect to the tilt fore and aft of the grounding parts of mobile devices canting and the back canting attitude alter operation mechanism of alter operation freely forward, detect the tilt forward and back angle detection mechanism of above-mentioned body main body with respect to the tilt fore and aft of level reference, with carry out the action of controlling above-mentioned attitude alter operation mechanism based on this detection information that tilts forward and back angle detection mechanism device with the attitude coutrol mechanism of the pitching control that above-mentioned body main body is maintained the target inclination angle with respect to the tilt fore and aft of level reference

For example, if because the body main body travel while advancing and enter into sloping floor etc. from smooth ground, the initial end that the center of gravity of body main body is crossed the sloping floor moves to the body front side and the body main body becomes the such situation of the attitude that leans forward, then detect the situation that the body main body departs from from the target inclination angle with respect to the tilt fore and aft of level reference, make above-mentioned attitude alter operation mechanism action with tilt fore and aft canting change backward the body main body so above-mentioned attitude coutrol mechanism is carried out by tilting forward and back angle detection mechanism, so that the body main body is maintained the attitude corrective action at target inclination angle with respect to the tilt fore and aft of level reference.And, after having carried out the attitude corrective action like this, judge that the body main body travelled before the setpoint distance, do not carry out with the inclination angle of body main body to based on the change side of attitude corrective action in the opposite direction, promptly before the attitude corrective action that changes of canting.
The result, if for example the width along the body direct of travel of sloping floor as described above is shorter, the body main body enters into such situation on the smooth field face immediately after smooth ground enters into the sloping floor, if then the body main body becomes the place ahead decline lateral attitude then carries out above-mentioned attitude corrective action, so can avoid the leading section of the direct of travel of body main body to touch the unfavorable of ground etc., and the body main body can not continue with respect to the heeling condition that the tilt fore and aft of level reference departs from from the target inclination angle, and the driver who takes carries out driver behavior easily.
In addition, before body main body behind the above-mentioned attitude corrective action of execution is travelled setpoint distance, not with the inclination angle of body main body to changing in the opposite direction with change side based on the attitude corrective action, carry out the situation that the rapid attitude of body main body changes repeatedly so the center of gravity that can avoid the body main body moves forward and backward with respect to the initial end of sloping floor.And, the body main body has been travelled after the setpoint distance after carrying out above-mentioned attitude corrective action, even make above-mentioned attitude alter operation mechanism action so that the body main body is maintained the target inclination angle with respect to the tilt fore and aft of level reference, the also unlikely initial end with respect to the sloping floor of the center of gravity of body main body moves forward and backward, and the rapid attitude that can not carry out repeatedly on the fore-and-aft direction of body main body changes.
Thereby, can provide a kind of when smooth ground enters into the sloping floor etc., can avoid carrying out repeatedly along with moving of center of gravity change of canting attitude backward and the change of canting attitude forward etc. fault generation and can avoid the leading section of body main body to touch ground or be difficult to carry out the disadvantageous attitude-control device of driver behavior etc.
