Description

Vehicle drive setting device and setting method thereof

The present invention relates to a vehicle drive setting device and a drive setting method, and more particularly to a vehicle drive setting device and a drive setting method for an electric vehicle or an electric vehicle.

Please refer to FIG. 1A and FIG. 1B for a schematic structural diagram of a prior art vehicle actuator. The actuator 10 includes a drive circuit 11, a motor 12, a gear set 13 and a drive setting module 14. The drive circuit 11 is connected to the battery 15 to be electrically operated and used to control the rotation of the motor 12. The rotation of the motor 12 drives the operation of the gear set 13, and the drive setting module 14 of the connected gear set 13 is displaced by the gear set 13. Therefore, the rotation time, the rotation angle and the number of rotations of the motor 12 affect the displacement distance and the stop position of the drive setting module 14.

The drive circuit 14 includes two microswitches 16 having a switch plate or switch. The drive setting module is configured with a rod 17.

Complete (such as multi-wheel drive or drive lock status). However, the motor 12 is rotated by the control of the drive circuit 11, but if the motor rotation speed is unstable, it is easier to cause the drive setting module 14 to stop at an incorrect position. If the motor rotates too fast, the rotation time is too long, the rotation angle is too large, or the number of rotation turns is too large, it is easy to cause the strut 17 to be caught between the switch plate of the micro switch 16 and the main body, and the switch board is damaged. Or, if the motor 12 rotates too slowly, the rotation time is too short, the rotation angle is too small, or the number of rotations is too small, it is easier for the support rod 17 to be pressed against the switch plate (or the switch key), and the micro switch 16 is less likely to be Trigger, the drive setting mode operation is incomplete or the drive mode setting of the generated vehicle is incorrect.

When the motor 110 rotates, the first gear 121 rotates, and the first gear 121 drives the second gear 122 to rotate. The pivot 123 of the second gear 122 and the drive setting module 130 correspond to each other. The spiral pattern, the drive setting module 130 is displaced by the second gear 122. The drive setting mode drives the action of the drive shaft 140 of the vehicle transmission system, thereby setting the operating mode of the transmission system.

The vehicle drive setting device 200 operates with the power provided by the battery 150. However, in order to obtain stable power for the vehicle drive setting device 200, a power stabilizing module 160, such as a circuit, component, device or system with voltage regulation and/or current stabilizing capability, may be added to the actuator 100. The power stabilization module 160 can also be combined with the drive circuit 210 described below.

The vehicle drive setting device 200 includes a magnetic unit 220 and a drive circuit 210. The magnetic unit 220 is disposed on the drive setting module 130. The driving circuit 210 is connected to the motor 110 and includes a plurality of magnetic sensing units 211 and a control unit 212. Wherein, when the magnetic unit 220 and the magnetic sensitive unit 211 are disposed, when the driving setting module 130 is displaced within an allowable displacement range, the magnetic unit 220 must be capable of being sensed by more than one sensing unit. The control unit 212 is configured to drive the rotation and stop of the motor 110, and adjust the driving setting of the motor 110 according to the sensing result of the magnetic unit 220 by the magnetic sensing unit 211, for example, the rotation speed, the rotation time, and the rotation circle of the motor 110. At least one of the number and the angle of rotation, or a combination of the two or more, thereby correcting the displacement of the drive setting module 130, so that the drive setting module 130 can be surely stopped at the corresponding position of the trigger related drive setting mode.

As described above, the magnetic unit 220 is a magnet or an electromagnet, but not limited thereto, and other similar magnetic elements are also applicable. The magnetic sensing unit 211 is a Hall element or a magnetic induction switch, and is not limited thereto. Other similar magnetic sensing elements are also applicable.

Residual power detecting circuit 230 The connection battery 150 and the driving circuit 210, or the residual power detecting circuit 230 can be combined in the driving circuit 210, and is not limited.

The residual power detecting circuit 230 is configured to detect the residual power of the battery 150. The control unit 212 adjusts the drive setting of the motor 110 according to the residual capacity of the battery 150. For example, when the residual power is higher than or equal to a power set value, the control unit 212 does not use the residual power of the battery 150 as a reference for adjusting the drive setting of the motor 110. On the other hand, when the residual power of the battery 150 is lower than the power set value, the control unit 212 calculates a compensation parameter according to the difference between the residual power of the battery 150 and the power set value, and according to the compensation parameter and the magnetic sensing unit 211 As a result of the induction of the magnetic unit 220, at least one of the rotational speed, the rotational time, and the number of revolutions of the motor 110 is adjusted, and the displacement distance and the stop position of the drive setting module 130 are corrected.

However, if the control unit 212 does not obtain any induction result of the magnetic unit 220 on the magnetic unit 220, the driving setting of the motor 110, that is, the rotation speed, the rotation time, and the number of rotations of the motor 110, is adjusted only according to the compensation parameter. At least one of them.

Please refer to FIG. 4 , which is a flowchart of a vehicle driving setting method according to an embodiment of the present invention. Please refer to FIG. 2A and FIG. 2B for understanding. The flow of the method is as follows: a magnetic unit 220 disposed in the drive setting module 130 is sensed by a plurality of magnetic sensitive units 211 (step S110). When the magnetic unit 220 and the magnetic sensitive unit 211 are disposed, when the driving setting module 130 is displaced within the allowable displacement range, the magnetic unit 220 must be capable of being sensed by more than one sensing unit.

A control unit 212 of the drive circuit 210 adjusts the drive setting of the motor 110 according to the sensing result of the magnetic unit 220 by the magnetic sensitive unit 211 (step S120). The drive setting of the motor 110 is, for example, at least one of a rotation speed of the motor 110, a rotation time, a number of rotations, and a rotation angle, or a combination of two or more. By the correction of the drive setting of the motor 110, the displacement of the drive setting module 130 can be corrected, so that the drive setting module 130 can be surely stopped at the corresponding position of the trigger related drive setting mode.

FIG. 5 is a flowchart of a method for setting a driving principle of a vehicle according to an embodiment of the present invention, which is performed in step S120 or after step S120. Please refer to Figure 2A and Figure 3 for easy understanding. This method flow description Bottom: The residual power of the battery 150 is detected by a residual power detecting circuit 230 (step S210). The residual power detecting circuit 230 is connected to the battery 150 and the driving circuit 210, or the residual power detecting circuit 230 can be combined in the driving circuit 210.

It is judged by the control unit 212 whether or not the amount of remaining electric power is lower than a power amount setting value (step S220). This power setting value is preset by the designer in the code or body executed by the control unit 212.

When the control unit 212 determines that the residual electric quantity of the battery 150 is higher than or equal to the electric quantity setting value, the driving setting of the motor 110 is adjusted only according to the sensing result of the magnetic unit 220 by the magnetic sensitive unit 211 (step S230). The control unit 212 does not use the residual amount of the battery 150 as a reference for adjusting the drive setting of the motor 110.

When the control unit 212 determines that the residual capacity of the battery 150 is lower than the power set value, a compensation parameter is calculated according to the difference between the residual power and the power set value, and the sensing result of the magnetic unit 220 is determined according to the compensation parameter and the magnetic sensitive unit 211. The drive setting to the motor 110 is adjusted (step S240).

6 is a flow chart of a method for setting a vehicle driving detail according to an embodiment of the present invention. Please refer to Figure 2A and Figure 3 for easy understanding. The flow of the method is as follows: Before the step S120, the control unit 212 determines whether or not the sensing result of the magnetic unit 211 on the magnetic unit 220 is obtained (step S310). If the control unit 212 obtains the sensing result of the magnetic unit 211 on the magnetic unit 220, that is, according to the above step S120, or more, in combination with the performing steps S210-240, the rotation speed, the rotation time, and the number of rotations of the motor 110 are adjusted. One of them.

When the control unit 212 determines that the sensing result of the magnetic unit 220 on the magnetic unit 220 is not obtained, the control unit 212 determines whether the residual power is lower than a power setting value to determine whether to adjust the driving setting of the motor 110 (step S320).

When the control unit 212 determines that the residual capacity of the battery 150 is lower than a power setting value, since the sensing result of the magnetic unit 220 by the magnetic sensing unit 211 is not obtained previously, only the difference between the residual power and the power setting value is calculated. a compensation parameter and an inductive junction of the magnetic unit 220 according to the compensation parameter The drive setting of the motor 110 is adjusted.

Conversely, when the control unit 212 determines that the residual power of the battery 150 is higher than or equal to a power setting value, the control unit 212 may depend on the operating state of the motor 110 because the sensing result of the magnetic unit 220 is not obtained previously. For example, the rotation speed, the rotation time, the number of rotations and the rotation angle of the motor 110 determine whether the driving setting of the motor 110 should be adjusted, or the motor 110 is driven by the previous operational setting, or a similar judgment technique, such as assuming The operational determination or simulation drives the operation of the module 130 to adjust or maintain the drive settings for the motor 110.

In summary, the present invention is only described as an embodiment or an embodiment of the technical means used to solve the problem, and is not intended to limit the scope of the invention.
