When motor bike slows down, as shown in Figure 8, adjust the height of vehicle according to 4 kinds of speed of a motor vehicle changing patteries by such control program.Promptly when motor bike slows down, set: vehicle velocity V is decelerated to the pattern 1 (MODE1) that stops from the 1st state of setting more than the vehicle velocity V I; Vehicle velocity V is from the 1st state of setting more than the vehicle velocity V I, reduce to the 2nd set vehicle velocity V 2 below after, become the pattern 2 (MODE2) of the 1st setting vehicle velocity V more than 1 again; Vehicle velocity V is set the state of vehicle velocity V 1 or more from the 1st, reduce to the 2nd set vehicle velocity V 2 below after, once more through the state of the 2nd setting vehicle velocity V more than 2, become the mode 3 (MODE3) of the 2nd setting vehicle velocity V below 2 then; Vehicle velocity V is set the state of vehicle velocity V 1 or more from the 1st, become the 1st set vehicle velocity V 1 below and the 2nd setting vehicle velocity V more than 2 after, be upgraded to the pattern 4 (MODE4) of the 1st setting vehicle velocity V more than 1 once more.And in pattern 1, when vehicle velocity V was set vehicle velocity V 1 less than the 1st, motor 35 beginnings were to low overall height one side action, even the speed of a motor vehicle is set vehicle velocity V 2 less than the 2nd, owing to be low overall height state, the 2nd setting vehicle velocity V 2 does not possess the function that triggers the speed of a motor vehicle to the conduct of low overall height one side action yet.In pattern 2, when vehicle velocity V is set vehicle velocity V 1 less than the 1st, motor 35 beginnings are to low overall height one side action, then the speed of a motor vehicle reach the 2nd set vehicle velocity V more than 2 after, motor 35 moves to high overall height one side, set vehicle velocity V more than 1 although the speed of a motor vehicle reaches the 1st, owing to be high overall height state, the 1st sets the speed of a motor vehicle can not play the effect that triggers the speed of a motor vehicle to the conduct of high overall height one lateral movement yet.At mode 3, when vehicle velocity V is set vehicle velocity V 1 less than the 1st, motor 35 beginnings are to low overall height one side action, although the speed of a motor vehicle is set vehicle velocity V 2 less than the 2nd, owing to be low overall height state, the 2nd sets vehicle velocity V 2 does not possess as the function to the triggering speed of hanging down the action of overall height one side yet, after this, when reaching the 2nd, the speed of a motor vehicle sets vehicle velocity V 2 when above, motor 35 moves to high overall height one side, when the speed of a motor vehicle was set vehicle velocity V 2 less than the 2nd, the 2nd sets vehicle velocity V 2 played a role as the triggering speed of a motor vehicle of moving to low overall height one side, and motor 35 makes it move to low overall height one side.In pattern 4, when vehicle velocity V was set vehicle velocity V 1 less than the 1st, motor 35 beginnings were to low overall height one side action.After this, set vehicle velocity V 1 when above when the speed of a motor vehicle reaches the 1st, motor 35 moves to high overall height one side.
In addition, when motor bike quickens, as shown in Figure 9, set: vehicle velocity V accelerates to the pattern 1 (MODE1) of the 1st setting vehicle velocity V 1 above state from halted state; Vehicle velocity V accelerates to the 1st and sets after the vehicle velocity V 1 above state, changes to the pattern 2 (MODE2) of the 1st setting vehicle velocity V 1 following state again; Vehicle velocity V change to the 2nd set vehicle velocity V 2 or more after, change to the mode 3 (MODE3) of the 2nd setting vehicle velocity V 2 following states again; Vehicle velocity V is in the pattern 4 (MODE4) of the state of the 2nd setting vehicle velocity V below 2.So in pattern 1, vehicle velocity V changes to the 2nd and sets vehicle velocity V 2 when above, motor 35 beginnings are moved to high overall height one side.In pattern 2, when changing to the 2nd, vehicle velocity V sets vehicle velocity V 2 when above, motor 35 beginnings are to high overall height one side action, the speed of a motor vehicle through becoming the 1st set the state of vehicle velocity V more than 1 after, when the speed of a motor vehicle becomes less than the 1st setting vehicle velocity V 1, the 1st sets vehicle velocity V 1 plays a role as the triggering speed of a motor vehicle of moving to low overall height one side, and motor 35 moves to low overall height one side.At mode 3, vehicle velocity V changes to the 2nd and sets vehicle velocity V 2 when above, motor 35 beginnings are to high overall height one side action, through becoming the 2nd set the state of vehicle velocity V more than 2 after, when the speed of a motor vehicle becomes less than the 2nd setting vehicle velocity V 2, the 2nd sets vehicle velocity V 2 plays a role as the triggering speed of a motor vehicle of moving to low overall height one side, and motor 35 moves to low overall height one side.Further in pattern 4,,, keep the state of low overall height so motor 35 is failure to actuate because of vehicle velocity V is under the state less than vehicle velocity V 2.
Effect to the 1st embodiment makes an explanation below.When adjusting overall height high and low, preestablish the 1st set vehicle velocity V 1 and Bi Di 1 set vehicle velocity V 1 low the 2nd set vehicle velocity V 2, when motor bike slows down, set the state of vehicle velocity V more than 1 in vehicle velocity V from the 1st, when continuing to reduce to less than the 2nd setting vehicle velocity V 2 states, the 1st sets vehicle velocity V 1 as playing a role to the triggering speed of a motor vehicle of low overall height one side action, by the action of overall height change device 28 overall height is reduced.Motor bike is when halted state is quickened again, when vehicle velocity V is set vehicle velocity V 2 when above from change to the 2nd less than the 2nd state of setting vehicle velocity V 2, the 2nd sets vehicle velocity V 2 as playing a role to the triggering speed of a motor vehicle of high overall height one side action, by the action of overall height change device 28 overall height is improved.Like this, during deceleration, by the 1st higher setting vehicle velocity V 1 motor 35 beginnings in the overall height change device 28 are moved to step-down overall height one side, thus, avoid after stopping through motor bike in from the process of opening time of computing time of sampling time of car speed sensor 54, electronic control unit 56 and motor 35, the motor bike overall height is reduced fully, stopping again.In addition, during the motor bike starting, motor 35 beginnings in the overall height change device 28 are moved to uprising overall height one side, promptly improve overall height thus, can not damage mood by bus by the 2nd lower setting vehicle velocity V 2.
And because the changing pattern difference of the speed of a motor vehicle, also changes to the low speed of a motor vehicle one side and to the setting speed of a motor vehicle of the high speed of a motor vehicle one side action, the pattern 4, the 1 when slowing down is set vehicle velocity V 1 and is played a role as the triggering speed of a motor vehicle of moving to the high speed of a motor vehicle one side; Mode 3 when quickening, the 2nd sets vehicle velocity V 2 plays a role as the triggering speed of a motor vehicle of moving to the low speed of a motor vehicle one side.Can adjust overall height corresponding to the speed of a motor vehicle variation of motor bike thus.
But, pattern 4 during deceleration, vehicle velocity V is just to change to the pattern of the 1st setting vehicle velocity V more than 1 from setting vehicle velocity V 2 for the state of low overall height without the 2nd, also have, mode 3 during acceleration, vehicle velocity V is from being the state of high overall height, sets vehicle velocity V 1 without the 1st and just becomes the pattern of setting vehicle velocity V 2 less than the 2nd.So going out overall height from these two mode detection is to be in low, high which state, set vehicle velocity V 1 and the 2nd according to its overall height location information decision with the 1st and set vehicle velocity V 2 as also being fine to high overall height one side and to the triggering speed of a motor vehicle of hanging down which the side action of overall height one side, at that rate, the corresponding motor bike speed of a motor vehicle can be adjusted overall height.
As other embodiment of the present invention, be to use detection side support 17 to stretch out the resistance switch (not shown) of state, also the state that can stretch out with side stand 17 is the position that the halted state of motor bike is used as low overall height.Use the differential value of driving engine throttle opening signal in addition, when this differential value is " 0 " substantially, promptly almost during the unmodified low speed driving, overall height is changed at throttle opening; When above-mentioned differential value negative value is big, be judged to be deceleration that throttle opening closed constantly; Above-mentioned differential value is judged to be acceleration that throttle opening opened constantly when big; Also can obtain above-mentioned judgement with the form that quickens the corresponding setting speed of a motor vehicle of the moment from reserving in advance with the moment of slowing down.In addition, be that be variable the opening time of motor 35 opening time that makes overall height change device 28, under the situation of the high speed of a motor vehicle, also can make above-mentioned opening time longer, so that alleviate the impact when low overall height one side is moved.
Figure 10 to Figure 14 is the scheme drawing of the present invention the 2nd embodiment, is being marked with identical label with the corresponding part of the 1st embodiment.
