    [1] [0001] The present invention relates generally to pedal feel simulating systemsfor a pedal device in motor vehicles.
    [2] [0002] Historically, vehicles such as cars had a purely mechanical pedal systemfor brakes, clutches and accelerator pedals. ln such mechanical pedal systems, apedal such as the brake pedal was mechanically coupled to the brake discs vialinks and a hydraulic system etc so that when the driver pressed the brake pedalthe car was automatically braked via the mechanical connection to the brakediscs. Nowadays, car manufacturers are moving from mechanical pedal systemsto electrical pedal systems. ln electrical pedal systems, the car is controlled from acomputer controlled system, actuated from the pedals in the car maneuveringdifferent sensors. ln the electrical pedal systems, there is a need to simulate forthe driver a mechanical pedal system so that the driver perceives that for e.g. thebrake, when he/she brakes harder, the car behaves as he/she is used to. This is important so that the driver feels comfortable behind the steering wheel.
    [3] [0003] ln prior art it is known to use pedals with springs counteracting thedepressing of the pedal. Such a pedal arm may act on a rotatably mounted leverarm to which a counter force is applied. The counter force may be generated by alever spring which may be supported in one end on the housing and on the other end on the lever arm.
    [4] [0004] A drawback of this type of pedals apparatus is that it neither generates apleasant feel for the driver, nor generates a feel that resembles the depressing ofan actual mechanical pedal such e.g. a clutch pedal. The pedal force constantlyincreases at a relatively high rate upon depressing the pedal. This is unnecessarystrenuous for the driver. Another drawback is that it requires shaping a specific contour of the lever arm in order to create a specific pedal force curve.
    [5] [0005] An object of the present invention is to alleviate some of thedisadvantages of the prior art and to provide a pedal feel simulating system for apedal device which is simple and better emulates the feeling of an actual mechanical pedal.
    [6] [0006] Another object of the present invention is to provide a pedal feelsimulating system for a pedal device which facilitates the creation of a plurality of separate pedal force curves depending on the need and requirements present.

    [33] [0033] According to one embodiment, the link arm 6 further comprises a thirdportion 6c, essentially corresponding to an end portion of the link arm 6. Accordingto one embodiment, the third portion 6c of the link arm 6 is a free end, for instanceis not rotationally connected to any other part. According to one embodiment, thethird portion 6c of the link arm 6 is closed, i.e. comprises means for preventing theguide element from sliding of the free end. Such means could e.g. be a lateralextension of the link arm 6 or a lateral extension portion formed on the link arm 6.According to one embodiment, a return spring is connected to the third portion 6cof the link arm 6, for creating a return force biased to return the pedal arm 2 fromthe second position to the first position. According to one embodiment, a returnspring is connected to the pedal arm 2 for creating a return force biased to return the pedal arm 2 from the second position to the first position.
    [34] [0034] According to one embodiment, a distance between the second portion 6band third portion 6c of the link arm 6, i.e. a straight line between the second 6band third portion 6c, is arranged with an angle oi in relation to the distance between the second portion 6b and the first portion 6a of the link arm 6, i.e. a straight line between the second 6b and first portion 6a.

According to one embodiment, the angle or isselected based on the desired length of the travel of the variable point p along thelink arm 6 as later described, i.e. by the length of the movement of the guide element 11 on the link arm 6.
    [35] [0035] The spring device 8 is arranged to the link arm 6 at a first portion 8a ofthe first spring device 8. According to one embodiment, the first portion 8a ispivotally arranged to the link arm 6 via a pivot shaft, preferably the pivot shaft 6a'.A second portion 8b of the spring device 8 is arranged to the bracket device 5.According to one embodiment, the second portion 8b is pivotally arranged to thebracket device 5 in a loose articulated manner, for instance by the aid of a joint orhinge member. According to one embodiment, the spring device 8 is pivotallyarranged to the bracket device 5, via a pivot shaft 8b”.

According to one embodiment, the plurality of springs may have different spring rates.
    [36] [0036] Fig. 1a and Fig. 1b shows a perspective view and a side viewrespectively of the pedal feel simulating system 1 for a pedal device 10 in a firstposition of the pedal arm 2. According to one embodiment the first positioncorresponds to an equilibrium state of the pedal feel simulating system 1.According to one embodiment, the first position corresponds to a state of the pedalfeel simulating system 1,wherein the pedal arm 2 is in its most expanded, i.e.least compressed or activated, state. Further, the guide element 11 is in a firstposition p along the link arm 6, and the spring device 8 is in its most extendedpositions available in the pedal feel simulating system 1. According to one embodiment, the spring device 8 is uncompressed in a first position of the pedal arm 2. According to one embodiment, the spring device 8 is slightly compressed inthe first position to avoid noise and vibration in the pedal feel simulating system 1.According to one embodiment, the pedal arm 2 rests against a stop (not shown)which prevents a returning movement further beyond the first position, whereby the spring device 8 can always be held slightly compressed.
    [37] [0037] Fig. 2a and Fig. 2b shows a perspective view and side view respectivelyof the pedal feel simulating system 1 for a pedal device 10 in a second position ofthe pedal arm 2 whereby the pedal arm 2 has pivoted around the pivot shaft 2a'from the position of Figs. 1a, 1b. Since the pivot points 2a' and 6b' are not in theidentical spatial position, i.e. the can be seen as two separate eccentric circularmovement paths, the guide element 11 have moved, e.g. slid, slightly along thelink arm 6, during the pivoting of the pedal arm 2 from the first towards the secondposition, i.e. the hysteresis portion 11d has slid along the surface 6d of the linkarm 6. Thus, the pedal arm 2 is adapted to act on the link arm 6 at the variableposition p creating a torque around pivot point 6b' causing the link arm 6 to rotate,wherein the position p changes during pivoting of the pedal arm 2.Thus, a force istransmitted from the pedal arm 2 via the guide element 11 to the link arm 6causing the pivot arm 6 to pivot around the pivot shaft 6b'. As a result, the springdevice 8 is caused to rotate and being compressed simultaneously with therotation of the link arm 6. According to one embodiment, the spring device 8rotates around pivot shaft 8b'. Thus, an increasing pedal force is generatedcounteracting the pivoting of the pedal arm 2 from the first position towards thesecond position. According to one embodiment, the distance from the variableposition p to the second portion 6b of the link arm 6 decreases during pivoting ofthe pedal arm 2 from the first to the second position. According to oneembodiment, the moment arm around pivot point 6b” will thus decrease requiring aincreasing pedal force to create the same magnitude of the torque around pivotpoint 6b”. This effect will contribute to the pedal force curve shown in Fig. 3.According to one embodiment, the distance from the position p to the secondportion 6b of the link arm 6 increases during pivoting of the pedal arm 2 from thefirst to the second position. According to one embodiment, the moment arm around pivot point 6b' will thus increase requiring a decreasing pedal force to create the same magnitude of the torque around pivot point 6b'. Thus, accordingto one embodiment, the variable position p corresponds to a variable or changing gearing during pivoting of the pedal arm 2.
    [38] [0038] The rotations of the link arm 6 and spring device 8 respectively can beseen as two separate eccentric circular movement paths around their respectivepivot points, 6b' and 8b'. The circular movement path of the link arm 6 will have aradius given by the radial extension length from the pivot point 6b' to the point 6a.According to one embodiment, such radial extension will correspond to the lengthfrom 6b to 6a provided this portion has a straight shape. The circular movementpath of the spring device will have a radius given by the spring device 8 lengthfrom the pivot point 8b' to the point 8a in a non-compressed state to the point 8a.These two circles will have an overlap, hence the rotation of the link arm 6 willcause the spring device 8 to be compressed during rotation of the link arm 6 alongwith the rotation of the spring device 8. Due to that the change of rate of theoverlap will vary during the rotation, so will the compression rate of the spring 8,and hence the rate of change of the resulting pedal force. This effect will contributeto the pedal force curve as seen in Fig. 3, having a steeply increasing pedal forceinitially during depression of the pedal 2, whereafter the pedal force will notincrease as steeply, i.e. will flatten out. Hence, according to one embodiment, acompression of the spring device 8 and thereby the resulting pedal force, initiallyincreases at a first rate and eventually increases at a second rate, wherein thesecond rate is lower than the first rate, during pivoting of the pedal arm 2 from the first to the second position.
    [39] [0039] According to one embodiment, the distance between the position ofwhere the second portion 6b of the link arm 6 is pivotally arranged to the bracketdevice 5, and the position of where the second portion 8b of the spring device 8 ispivotally arranged to the bracket device 5, and the distance between the firstportion 6a and the second portion 6b are selected such that the spring device 8 ismaximally compressed 30% of the entire free, or un-compressed, length of thespring device 8 during a pivoting between a first position towards a second position. According to one embodiment, such selection will allow the spring to pass 11 life-span requirements. The variables are thus several, and the selection may bebased on the conditions and requirements of the pedal simulating systems as wellas the pedal device 10 in general. For instance, if there is much space in thecompartment of the vehicle, a longer spring with lower spring rate may be used. lnsmaller compartments, the spring may have to be arranged in unsuitable locationswhich may require the spring to be short spring with high spring rate. According toone embodiment, the selection may be made such that an over-center movementof the spring 8 is allowed during depression of the pedal arm 2, i.e. wherein thespring is allowed to extend, i.e. decompress in a later part of such movement.Thus, if required for the pedal device application in question, and intended usethereof, a pedal force curve may be created which decreases during the late partof the depression movement. According to one embodiment, in such cases, theuse of a return spring arranged on the link arm 6 as described above may be particularly useful to return the spring device 8.
    [40] [0040] Figs. 3 shows the pedal force acting on the driver in relation to theamount of depression or movement or pivoting of the pedal arm 2, i.e. in relation tothe positions described in Figs. 1a, 1b, and Figs. 2a, 2b with correspondingmarkings a, b referring to said positions respectively in Fig. 3. Fig. 3 shows a pedalforce curve wherein the pedal feel simulating system 1 for a pedal device 10 maysuitably be used in a clutch pedal device, i.e. wherein the variables of the pedalfeel simulating system 1 described above have been selected to achieve thispedal force curve. As can be seen in Fig. 3, the hysteresis effect is shown in thedrop of the pedal force curve following a reaching of the second position of thepedal arm 2 and the allowing of a movement towards the first position. Thehysteresis effect is desirable since a driver should desirably sense that a releasingof the pedal arm or reducing of the load/pedal force on the pedal arm 2 does notresult in that the pedal arm 2 moves to fast from the second towards the firstposition. The hysteresis effect is generated for instance from the hysteresiselement 11d and any internal friction in the pedal simulating system 1, such asfriction within the spring or in the connections between the described movableparts of the pedal simulating system 1. 12
