Description

Software self-resetting system of electronic gear shifter

Technical Field

The utility model relates to an electron selector technical field especially relates to an electron selector software is from reset system.

Background

When the electronic gear shifter is actually applied, the driving gear shifting intention can be judged according to the poking direction of the poking rod or the rotating direction of the knob. For example, a rightward operation is a forward shift (N → D or R → N), and a leftward operation is a reverse shift (D → N or N → R). Wherein R represents reverse gear, N represents neutral gear, and D represents forward gear. And can use elasticity to reset to the original point from the beginning of a day structurally, so that the driving operation can be finished and the driving lever or the knob can automatically return to the original point after the hands are loosened, and the next operation is prepared.

The self-reset design of the structure has higher technical requirements on the mechanism, and the structure is not stopped at a fixed point due to the weakened aging elasticity or the interference of external force when the real vehicle runs. Once the shift lever or the knob is not at the fixed position, that is, stuck, because the hall element does not sense the magnet and does not output, the abnormal phenomenon may cause malfunction of the system.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides an electron selector software is from reset system can avoid the erroneous judgement and can keep electron selector normal operation when the structure is from resetting inefficacy.

In order to realize the technical scheme, the utility model provides an electron selector software is from reset system, including control panel, hall subassembly, magnet and driving lever/knob be provided with the original point axis on the control panel and with crossing first position axis and the second position axis in the axle center of original point axis, first position axis and second position axis all are provided with hall subassembly, original point axis, first position axis and the crossing axle center department of second position axis are provided with the knob and be provided with the driving lever below the knob, by knob control driving lever rotates around the axle center be provided with magnet on the driving lever, hall subassembly mutual-induction on magnet and the control panel.

The further improvement lies in that: the number and distribution of the Hall components are designed according to different structures.

The further improvement lies in that: when the knob controls the shifting lever to fix the point on the original point axis, the first position axis and the second position axis, the corresponding Hall assembly on the control board senses the magnet on the shifting lever and outputs a sensing result, and when the sensing result when the shifting lever is located at the fixed point on the first position axis and the second position axis is that the magnet is located at the position, the current position of the shifting lever is determined to be at the original point axis.

The further improvement lies in that: the magnet is fixed on the shifting lever and moves along with the shifting lever so as to provide a magnetic field for the Hall assembly to mark the moving position.

The utility model has the advantages that: the utility model discloses the software that adopts is from reset system, is suitable for the electron gear shifter at single state (from resetting back to the original point), many location (left one, right one, left two, right two, etc.) points. The method of redefining the judgment logic of the original point position as not being in other positions can solve the problem that the Hall assembly output is not in accordance with the definition due to the structural jamming, can save the Hall assembly of the original point, is more reliable and reduces the cost compared with the common electronic gear shifter.

Detailed Description

In order to deepen the understanding of the present invention, the following embodiments will be combined to make the present invention do further details, and the present embodiment is only used for explaining the present invention, and does not constitute the limitation of the protection scope of the present invention.

According to the figures 1 and 2, the embodiment provides an electronic gear shifter software self-resetting system which comprises a control plate 1, a Hall assembly 2, a magnet 3 and a shifting lever/knob, wherein an original point axis 4, a first position axis 5 and a second position axis 6 intersecting with the axis of the original point axis are arranged on the control plate 1, the Hall assembly 2 is arranged on each of the first position axis 5 and the second position axis 6, the knob is arranged at an axis 7 where the original point axis 4, the first position axis 5 and the second position axis 6 intersect, the shifting lever 8 is arranged below the knob, the shifting lever 8 is controlled by the knob to rotate around the axis 7, the magnet 3 is arranged on the shifting lever 8, and the magnet 3 and the Hall assembly 2 on the control plate 1 are mutually induced.

The number and distribution of the hall elements 2 are designed according to different structures.

When the dial 8 is controlled by the knob to be positioned on the original point axis 4, the first position axis 5 and the second position axis 6, the corresponding Hall assembly 2 on the control board 1 senses the magnet 3 on the dial and outputs a sensing result, and when the dial 8 is positioned on the first position axis 5 and the second position axis 6 at the fixed points, the sensing result is that the magnet is positioned at the position, and the current position of the dial is determined to be positioned on the original point axis.

The magnet 3 is fixed to the shift lever 8 and moves with the shift lever to provide a magnetic field for the hall element to calibrate the position of movement.

Fig. 3 is a block diagram of a typical electronic shifter jamming, and table 1 below is a general electronic shifter lever/rotational position determination condition:

toggle/rotational position	Determination conditions
		Axis of origin	Hall output of origin axis is 1
First position axis	First position axis Hall output is 1
		Second position axis	Second position axis Hall output is 1

Note: output 1 represents the magnet in position; output 0 represents the magnet is not in position.

Table 2 below shows the software self-resetting electronic shifter lever/rotational position determination conditions in this example

Toggle/rotational position	Determination conditions
		Axis of origin	The Hall outputs of the first/second position axes are all 0
First position axis	First position axis Hall output is 1
		Second position axis	Second position axis Hall output is 1

Therefore, when the structure fails to return the shift lever/knob to the original point due to the aging of the self-reset elastic force or the interference of external force, the jamming phenomenon is shown in fig. 3, and the outputs of the three hall signals are all 0, which is not in the logic listed in table 1, and the electronic shifter fails to operate normally. In this state, the driver can still normally rotate left and right to the target position, and the structure cannot automatically rebound to the fixed point of the origin. Therefore, the present embodiment defines the software self-reset logic as shown in table 2, the position can be determined to be at the origin only by changing the determination condition of the origin position, and when the hall outputs of the first/second position axes are all 0, so that the position detection requirement of the original shifter can be maintained, and the position determination of the present embodiment does not need the hall output of the origin, so that the hall element on the origin can be omitted, thereby saving the production cost.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
