Or the controller 20 is used to periodically acquire the current position of the key 200 relative to the car 100; the periphery of the automobile is divided into a plurality of functional areas and a transition area for connecting the two functional areas; the functional area comprises a core area and a transition area, and the transition area is a strip area in a certain range at the boundary line side of the adjacent functional areas; the system comprises a functional area, a functional area and a functional area, wherein the functional area is used for updating the area ranges of the effective active functional area and the effective adjacent functional area and replacing the area range of the functional area to which the functional area belongs with the area ranges of the effective active functional area and the effective adjacent functional area in each period; and a function area for confirming that the key 200 is currently located based on the current position of the key 200; and for confirming, at each cycle, the functional zone in which the key 200 is currently located, based on the current position of the key 200; and for counting the number of times the key 200 is respectively located in each functional zone within a predetermined number of cycles; and is used in each cycle, if there is a certain functional area, the number of times that the key 200 locates in this functional area in the predetermined number of cycles is greater than the affiliated functional area predetermined number of times, this functional area is upgraded to the new active functional area, otherwise keep the original active functional area unchanged; and controlling the automobile to execute the preset function corresponding to the active functional area.

In the control method, the control device 300 and the automobile 100 of the embodiment of the application, the control device 300 implements the control method, the active extended function area is dynamically generated, the area ranges of the effective active function area and the effective adjacent function area are updated, and the area range of the function area to which the active function area and the effective adjacent function area belong is replaced by the area range of the effective active function area and the effective adjacent function area, so that when the key 200 moves near the handover boundary of different function areas around the automobile, frequent switching of preset functions of the adjacent function areas caused by random positioning errors can be effectively reduced, the loss of parts of the automobile 100 is reduced, and the user experience is improved.

Specifically, the automobile 100 may be a new energy automobile, a fuel automobile, a hybrid automobile, and the like. The key 200 of the automobile 100 may be a device used to enter the automobile 100, lock the automobile 100, or execute certain functional control commands on the automobile 100. The key 200 may be a remote control key, a key to which various wireless technologies are applied, or a digital key in an electronic device such as a mobile phone. For example, the key 200 may be an LF/UHF PEPS fob, a BLE digital key, a UWB digital key, and the like. The automobile 100 may include a controller 20 and a memory 10, the controller 20 may be configured to collect information of positioning sensors such as UWB/BLE distributed on the automobile body and calculate the position of the key 200, and the automobile 100 may implement the control method through the controller 20 and the memory 10.

In the control method, the controller 20 may periodically acquire the time length of the cycle for each positioning of the key 200, and may acquire the current position of the key 200 relative to the automobile 100 in step S10. The obtaining manner may adopt a positioning technology such as a positioning calculation system of the key 200 by the automobile 100, for example, the positioning calculation system may position the key 200 based on UWB TOF (Time of Flight) distance information with the key 200 acquired by a plurality of UWB anchor points at the vehicle end, position the key 200 based on RSSI received signal strength information with the key 200 acquired by a plurality of anchor points at the vehicle end, auxiliary positioning of vehicle end vision/ultrasonic waves/sound waves and the like, and relative positioning of an accelerometer at the key 200 end; the coordinates (position) of the key 200 with respect to the body coordinate system of the automobile 100 can be obtained by positioning the key 200 by the automobile 100, and thus the current position between the automobile 100 and the key 200 can be obtained.

The function area where the key 200 is currently located can be confirmed in step S20 based on the current position (coordinates) of the key 200 obtained in step S10. The confirmation method may be to compare the current position (coordinate) of the key 200 with the boundary positions (coordinates) of all functional areas, and determine whether the key 200 or the user carrying the key 200 is in an active functional area of a certain functional area by using the relative positional relationship between the current position of the key 200 and the automobile 100 and combining a positioning technique. The outer contour of the automobile 100 may be divided into blocks with predetermined functions, and each function block includes a core region and a transition region. The transition area is a strip area in a certain range at the boundary line side of the adjacent functional areas.

At any one time, the automobile 100 only executes the preset function of a certain functional area, which is called as the active functional area at that time; the transition area corresponding to the border line in the adjacent functional area outside the border line to be crossed by the key 200 is called active functional area extension, and the active functional area extension are combined together to be called effective active functional area; the remaining area after the active functional area expansion is removed from the adjacent functional area is called an effective adjacent functional area;

as further understood from fig. 3, the functional area of the automobile 100 may be divided according to different positions around the automobile 100, and a distance range outside the outline of the automobile 100 may be divided into the main functional area 30, and the specific value of the distance range may be selected to be about 0 m to 2 m. The distance range outside the main functional area 30 of the automobile 100 can be divided into the secondary functional area 40, and the specific value of the distance range can be selected to be divided into a plurality of distance sections from about 2 meters to about 30 meters.

The main functional area 30 may be divided into a plurality of functional blocks according to different components of the automobile 100, for example, the main functional area 30 of the automobile 100 is divided into 6 functional blocks, including a front left door functional block 31, a rear left door functional block 32, a front right door functional block 33, a rear right door functional block 34, a rear left door functional block 35 and a rear right door functional block 36. Each functional block can be further divided into a core area and a transition area, the transition area is close to an extension area of the adjacent functional block towards the direction opposite to the intersection line, and the core area can be an area close to the transition area and jointly form the functional block with the transition area.

For ease of understanding, the functional blocks into which the main functional blocks in fig. 3 are divided may be further divided into a left front door functional block transition region 311 and a left front door functional block core region 312, a left rear door functional block transition region 321 and a left rear door functional block core region 322, a right front door functional block transition region 331 and a right front door functional block core region 332, a right rear door functional block transition region 341 and a right rear door functional block core region 342, a rear door left functional block transition region 351 and a rear door left functional block core region 352, a rear door right functional block transition region 361 and a rear door right functional block core region 362.

Taking the left front door function block 31 and the left rear door function block 32 shown in the above figures as an example, if the automobile 100 currently executes the preset function of the left front door function block 31 at a certain time, the left front door function block 31 is the active function area at the time, the left rear door function block transition area 321 adjacent to the left front door function block 31 is the active function area extension, the left front door function block 31 (including the core area 312 and the transition area 311) and the left rear door function block transition area 321 may be merged into the effective active function area, and the left rear door function block core area 322 is called the effective adjacent function area.

Thus, when the key 200 is located in the active functional area of a functional block, the automobile 100 may implement the unlocking function of the corresponding functional block, for example, unlocking the front left door, unlocking the rear left door, and the like. When the key 200 leaves the active functional area of a functional block, the active functional area and the active adjacent functional area are updated, and the automobile 100 can execute the preset function corresponding to the functional area to which the new active functional area belongs, and can lock the previous functional block, for example, the left front door, the left rear door, and the like. Of course, the specific functions of the functional blocks may be set to other functions.

In the sub-functional area 40, the boundary from the main functional area 30 to the sub-functional area 40 may be a circular block, as shown in the sub-functional area 40 of two circular blocks surrounded by each other. When the key 200 is located in the annular blocks at different distances from the vehicle body, the vehicle 100 can be controlled to turn on the courtesy light, adjust the seat, turn on the air conditioner, and the like; in some sub-blocks of the ring-shaped (such as 2 m-6 m) block close to the main functional area, one or more of remote control parking or automatic following functions can be executed. Further, the function of the sub-functional area 40 can be customized according to the actual or user requirement of the automobile 100.

It should be further understood that, because the output of the positioning technology such as the positioning calculation system and the like when acquiring the position of the key 200 is a random probability distribution with the actual position of the key 200 as the center, the position coordinates of the output key 200 will randomly fall into the functional areas adjacent to the boundary line; if the function is not processed, the function executed by the automobile is frequently and randomly switched between the preset functions of the two adjacent functional areas; a phenomenon similar to this is commonly referred to as a ping-pong effect of the functional zone boundaries.

Step S30 is further adopted, in each period, the area ranges of the effective active function area and the effective adjacent function area are updated, and the area ranges of the effective active function area and the effective adjacent function area are used for replacing the area ranges of the function areas to which the effective active function area and the effective adjacent function area belong; that is, in each period, the adjacent functional blocks are updated, so that the area ranges equivalent to the effective active functional area and the effective adjacent functional area replace the original home area in the functional blocks.

Step S40 may then be taken to identify, at each cycle, the functional zone in which the key 200 is currently located based on the current position of the key 200; after the functional areas are equalized in step S30, the functional area where the key 200 is currently located can be identified based on the current position of the key 200.

Step S50 may then be taken to calculate, in each cycle, the number of times the key 200 is respectively located in each functional area within a predetermined number of cycles, noting that at this time, the regions of the functional areas corresponding to the active functional area and the active adjacent functional area are to be replaced with the regions of the active functional area and the active adjacent functional area; the predetermined number of cycles may be a specific number of cycles set in advance for the current position of the key 200 with respect to the automobile 100 acquired in step S10, the predetermined number of cycles may be 10 cycles, 16 cycles, or the like, and the number of times the key 200 is located in each functional zone may be calculated within a fixed cycle.

Then, step S60 may be taken, in each period, the number of times that the key 200 falls in a certain functional area within a predetermined number of cycles may be calculated, and corresponding predetermined numbers of times are set for different functional areas, and when the number of times that the key 200 falls in a certain functional area within a predetermined number of cycles is greater than the predetermined number of times of the functional area, the controller 20 may regard the functional area meeting the requirement as an active functional area, otherwise, the original active functional area is kept unchanged.

It will be appreciated that the predetermined number is a numerical threshold for comparison with the number of times the key 200 is located in the same functional zone within a predetermined period, and that a change in the active functional zone will be initiated when the comparison exceeds the predetermined number.

Then, step S70 may be adopted, if the functional area confirmed in step S60 is a new active functional area, a new active functional area and a new active adjacent functional area are generated, and the area of the corresponding functional area in which the new active functional area is located is replaced by the area of the new active functional area and the area of the active adjacent functional area, and then the automobile 100 is further controlled to execute a preset function corresponding to the active functional area to which the new active function belongs; otherwise it is inconvenient to keep the state of the previous cycle.

Referring to fig. 4, in some embodiments, the control method includes:

and S80, if the functional area where the key 200 is located is updated in a new period, the new period active functional area is updated, controlling the function executed by the automobile 100, and switching the preset function of the previous period active functional area to the preset function of the new period active functional area.

The control module 340 is configured to control the function executed by the vehicle in a new period if the function area in which the key 200 is located is updated in the new period, and the function executed by the vehicle is switched from the preset function of the previous period active function area to the preset function of the new period active function area. The controller 20 is configured to control the function executed by the automobile 100 to switch from the preset function of the previous active function area to the preset function of the new active function area in the new period when the active function area in the new period is updated due to the update of the function area where the key 200 is located.

Thus, the control method can cause the update of the active functional area where the key 200 is located according to the update of the position of the key 200 in the current period, further cause the area update of the new effective active functional area and the new effective adjacent functional area, further cause the area update of the functional areas to which the new effective active functional area and the new effective adjacent functional area belong, and the update of the preset function executed by the automobile (the new active functional area corresponds to the preset function), so that the frequency of switching the key 200 in the adjacent functional areas can be obviously reduced.

Specifically, if the function area in which the key 200 is located is updated in the new period, the function executed by the automobile 100 is controlled, and the function preset in the active function area in the previous period is switched to the function preset in the active function area in the current period.

Referring to fig. 5, in some embodiments, the current position of the key 200 relative to the automobile 100 is periodically obtained (step S10), which includes:

s11, periodically acquiring the distances between a plurality of UWB anchor point modules 50 on the automobile 100 and the key 200 respectively, wherein the UWB anchor points are positioned at different positions of the automobile 100;

and S12, calculating the current position of the key 200 relative to the automobile 100 based on the distances between the key 200 and a plurality of UWB anchor points on the automobile body.

The acquiring module 310 is configured to periodically acquire current distances between the UWB anchor modules 50 on the automobile 100 and the key 200, respectively, where the UWB anchors are located at different positions of the automobile 100; the calculation module 330 is configured to calculate a current position of the key 200 relative to the automobile 100 based on distances between the key 200 and a plurality of UWB anchor points on the automobile body.

The controller 20 is configured to periodically obtain current distances from the key 200 to the UWB anchor modules 50 of the automobile 100, respectively, where the UWB anchor modules are located at different positions of the automobile 100; and for calculating the current position of the key 200 relative to the car 100 based on the distances between the current plurality of keys 200 and the car body UWB anchor point.

In this manner, a more accurate current location of key 200 may be obtained by the plurality of UWB anchor modules 50 of vehicle 100, which may in turn be a more accurate determination of the functional zone in which key 200 is located.

Specifically, the UWB technology based on the 802.15.4z and other related standards, also called a security enhanced ultra wide band technology, may be mainly applied to the digital key 200 system of the automobile 100, and has the technical characteristics of relay attack prevention, high ranging and positioning accuracy; the key 200 can be identified inside and outside the vehicle and positioned accurately outside the vehicle functionally. The precision can reach +/-6-10 cm under the non-shielding condition, and the precision can reach +/-30 cm under the shielding condition.

The digital key system adopting the UWB technology can provide functions of noninductive unlocking, noninductive starting ignition and the like with good user experience. Exemplarily, the safety enhanced UWB technology based on 802.15.4Z, the low-power Bluetooth (BLE) technology and the Near Field Communication (NFC) technology are adopted, so that the vehicle can be unlocked and started noninductively by using electronic devices such as a mobile phone, remote sharing of a digital key can be conveniently carried out, the vehicle can be conveniently shared with family members, and the vehicle use of friends can also be authorized in a short time.

To implement step S10, step S11 may be taken, and the controller 20 may periodically acquire the current distance between each UWB anchor module 50 of the plurality of UWB anchor modules 50 on the automobile 100 and the UWB module on the key 200, wherein the plurality of UWB anchor modules 50 may be disposed at different positions of the automobile 100, for example, may be disposed near four corners (front left/rear right/front right) of the automobile 100 and near front and rear doors of the automobile 100.

Step S21 may then be taken, locating the relative position of the key 200 and the car 100 according to the plurality of current distances obtained in step S11; then, step S22 may be taken, and based on the relative position located in step S21, the functional region where the key 200 is located may be confirmed by calculating the relative position.

Illustratively, as can be further understood in conjunction with fig. 6, in the signal connection and positioning process between the key 200 based on UWB technology and the automobile 100, the automobile body may have a UWB positioning module (anchor point), a BLE (bluetooth low energy) communication module, an ultrasonic module, and a visual auxiliary module, and the key 200 may have a UWB module, a BLE bluetooth low energy module, an accelerometer, and other modules for positioning, which may include corresponding chips and modules; the bluetooth low energy module in the key 200 and the bluetooth low energy module in the car 100 can realize wireless communication and location based on received signal strength RSSI, and the UWB module in the key 200 and a plurality of UWB anchor modules 50 distributed in the car 100 carry out ToF ranging to can acquire the current distance of the key 200.

Then, toF distances between the UWB anchor modules 50 at the end of the vehicle 100 and the UWB module of the key 200 and RSSI information of received signal strength may be sent to the controller 20 of the vehicle 100 to perform position calculation of the key 200, so as to obtain a relative position of the key 200. The information obtained by the accelerometer, the ultrasonic module and the vision module of the key 200 can also be used for resolving assistance of the relative position of the key 200. The controller 20 then further determines the functional zone in which the key 200 is located based on the relative position of the key 200 with respect to the vehicle 100.

Referring to fig. 7, in some embodiments, counting the number of times that the key 200 is respectively located in each functional area for a predetermined number of cycles (step S50) includes:

s51, in each period, the counting of the functional area where the current position of the key 200 is positioned is increased once, and the counting of other functional areas is not changed;

and S52, confirming the times of the key 200 in each functional area according to the counting result of each functional area in the preset number of cycles.

The calculating module 330 is configured to count the functional area where the current position of the key 200 is located once in each period, and count other functional areas except the functional area unchanged; and a number of times for confirming that the key 200 is respectively located in each cycle based on the counted result of each functional area in the predetermined number of cycles.

The controller 20 is configured to count the functional area where the current position of the key 200 is located, by one time in each cycle, and count other functional areas except for the functional area; and a number of times for confirming that the key 200 is respectively located in each cycle based on the counted result of each functional area in the predetermined number of cycles.

Thus, the number of times the key 200 is located in each functional area in the cycle can be recorded by adopting a counting mode, and the key 200 can be conveniently positioned between the functional areas for comparison, so that the judgment of the subsequent steps is facilitated.

Specifically, the controller 20 may first take step S51 to perform step S50, and count the functional region where the key 200 is located once in each period of the predetermined number of periods, and then count the corresponding times of the valid active functional region, the valid adjacent functional region, and the other functional regions where the key 200 is located, which are confirmed in the predetermined number of periods.

As will be further understood in conjunction with the embodiment of fig. 8, taking the left front door functional block 31 and the left rear door functional block 32 shown in fig. 3 as an example, the controller 20 in the automobile 100 may execute step S50 when the key 200 is located at different positions from the boundary line of the two functional blocks. The number of times that the automobile 100 calculates the predetermined number of cycles may adopt a sliding window counting manner in software logic, taking a sliding window shift register set as an example:

in each period, updating is carried out on the sliding window shift register group and the counting accumulator which belong to each functional area in all the functional areas. When the key 200 is located in a functional area, the sliding window shift register set of the functional area can receive the update information "1", and other functional areas can receive the update information "0"; the shaded cells of the sliding window shift register group in the drawing represent information "1", and the blank cells of the sliding window shift register group in the drawing represent information "0". The length of the sliding window shift register set can be regarded as a predetermined number of cycles, and the predetermined number of cycles in the figure is 10; each sliding window shift register group is accompanied with a counting accumulator which is used for calculating the number of '1' in the sliding window shift register group;

when the active function area in front of the key 200 is the front left door function block 31, the front left door function block core area 312, the front left door function block transition area 311, and the rear left door function block transition area 321 together form an effective active function area, and the area range of the effective active function area replaces the area range of the front left door function block 31, and at this time, the area range of the function area 31 is increased by the rear left door function block transition area 321. The left back door functional block core area 322 becomes the valid adjacent functional area, and the area range of the left back door functional block 32 is replaced by the area range of the valid adjacent functional area, at which time the area range of the left back door functional block 32 loses the left back door functional block transition area 321. If the key 200 is located in the left front door functional block 31, the position of the key 200 is determined as a normal distribution curve centered on the actual position of the key 200. At this time, the sliding window shift register set in the front left door function block 31 confirms that the key 200 falls into the front left door function block 31 for 8 times and falls into the rear left door function block transition area 321 for 1 time within 10 predetermined number of cycles, since the rear left door function block transition area 321 belongs to the active function area. Therefore, the count accumulator accumulates 9 times. Meanwhile, the sliding window shift register bank in the left back gate function block core 322 confirms that the key 200 falls into the left back gate function block 32 for 1 time in 10 predetermined number cycles (at this time, the range of the function block of the left back gate function block 32 is only the left back gate function block core 322), so the number of times accumulated by the count accumulator is 1.

At this time, the predetermined number of times in the figure is 7, and the number of times accumulated by the counting accumulator in the active function area where the front left door function block 31 is located is greater than 7. Therefore, according to step S40, the front left door function block 31 may be determined as the active function area, and then step S70 may be implemented to control the automobile 100 to execute the preset function corresponding to the active function area. For example, unlocking of the left front door.

In some embodiments, the predetermined number of cycles is the latest predetermined number of cycles consecutive to the current time instant.

Thus, the number of times the key 200 falls into each functional area within a predetermined number of cycles is updated every cycle, thereby ensuring that the active functional areas are in the latest state.

Referring to fig. 9, in some embodiments, the control method further includes:

and S90, in each period, if the times that the key 200 is located in the same functional area in the preset period are all smaller than or equal to the preset times, the active functional area is not updated, and the function currently executed by the automobile 100 is not changed.

The control module 340 is configured to, in each cycle, if the number of times that the key 200 is located in the same functional area in the predetermined number of times is less than or equal to the predetermined number of times, not update the active functional area, and not change the function currently executed by the vehicle 100. The controller 20 is configured to, in each cycle, if the number of times that the key 200 is located in the same functional area in the predetermined number of cycles is less than or equal to the predetermined number of times, not update the active functional area, and not change the function currently performed by the vehicle 100.

In this way, when the number of times that the key 200 is located in the same functional area is less than or equal to the predetermined number of times, the function currently performed by the vehicle 100 is kept unchanged, and frequent switching of the function performed by the vehicle 100 (ping-pong effect) caused by random positioning errors when the key 200 is located near the boundary line can be reduced.

Specifically, as can be understood from fig. 10, when the position of the key 200 is moved from fig. 8 to fig. 10, and the active function area in front of the key 200 is the left front door function block 31, the left front door function block core area 312, the left front door function block transition area 311, and the left rear door transition area 321 form an active function area, the area of the active function area replaces the area of the original left front door function block 31, and other attributes of the left front door function block 31 are not changed. The left back door functional block core area 322 constitutes an effectively contiguous functional area, replacing the area of the original left back door functional block 32 with the area of the effectively contiguous functional area, with the other attributes of the left back door functional block 32 unchanged. If the key 200 is located in the transition region 311 of the left front door function block, the position of the key 200 is determined as a normal distribution curve centered on the actual position of the key 200. At this time, the sliding window shift register set in the left front door function block 31 confirms that the key 200 falls into the left front door function block transition area 311 and the left front door function block core area 312 for 7 times and falls into the left rear door function block core area 321 for 1 time within 10 predetermined number of cycles, and at this time, the number of times the counting accumulator accumulates is 8 times because the left rear door function block core area 321 belongs to the active function area. At the same time, the sliding window shift register set of the left back door functional block 32 confirms that the key 200 falls into the left back door functional block transition block 322 (valid adjacent functional block) 2 times within 10 predetermined number of cycles, so that the count accumulator of the left back door functional block 32 accumulates 2 times.

At this time, the predetermined number of times in the figure is 7, and the number of times accumulated by the counting accumulator in the active functional area where the front left door functional block 31 is located is greater than 7. Therefore, the left front door functional block 31 may be determined as the active functional area, and then the step S70 may be implemented to control the automobile 100 to execute the preset function corresponding to the active functional area. For example, the automobile 100 remains unlocked from the left front door.

As will be understood from fig. 11, when the state of the key 200 moves from fig. 10 to fig. 11, and the active function area before the key 200 is the front left door function block 31, the front left door function block core area 312, the rear left door function block transition area 311, and the rear left door transition area 321 form an active function area. The left back door functional block core area 322 becomes the active neighbor functional area. If the key 200 is located on the boundary line between the transition region 311 of the left front door functional block and the transition region 321 of the left rear door functional block, the position of the key 200 is determined as a normal distribution curve centered on the actual position of the key 200. At this time, the sliding window shift register set in the left front door function block 31 confirms that the key 200 falls into the left front door function block transition area 311 and the left front door function block transition area 312 for 5 times and falls into the left rear door function block transition area 321 for 1 time within 10 predetermined number of cycles, and since the left rear door function block transition area 321 belongs to the active function area, the number of times accumulated by the counting accumulator is 6 times. At the same time, the sliding window shift register bank of the left back gate functional block 32 confirms that the key 200 falls into the valid adjacent functional block (i.e., the left back gate functional block core 322) 4 times within 10 predetermined number of cycles, so the count accumulator accumulates 4 times. In this case, the predetermined number of times is 7 times, the number of times accumulated by the count accumulator of the front left door functional block 31 is 6 times smaller than 7 times, and the number of times accumulated by the count accumulator of the rear left door functional block 32 is 4 times smaller than 7 times. Thus, controlling the car 100 according to step S70 ensures that the previously executed state is unchanged, i.e. the preset function of the corresponding active functional zone executed in fig. 10. For example, the automobile 100 remains unlocked from the left front door.

As will be further understood with reference to fig. 12, when the key 200 continues to move to the position of fig. 12, the active function area in front of the key 200 is the left front door function block 31, the left front door function block core area 312, the left front door function block transition area 311, and the left rear door function block transition area 321 constitute an active function area, and the left rear door function block core area 322 becomes an active adjacent function area. If the key 200 is located in the transition area 321 of the left rear door function block, the position of the key 200 is determined as a normal distribution curve centered on the actual position of the key 200. At this time, the sliding window shift register set in the left front gate function block 31 confirms that the key 200 falls into the left front gate function block core area 312 for 1 time, the left front gate function block transition area 311 for 2 times, and the left rear gate function block transition area 321 for 3 times within a predetermined number of cycles of 10 times, so that the number of times accumulated by the count accumulator is 6 times. At the same time, the valid neighbor sliding window shift register set confirms that key 200 falls into valid neighbor function 322 4 times within 10 predetermined number periods, so the count accumulator counts 4 times. At this time, the predetermined number of times in the figure is 7, and the number of times accumulated by the counting accumulator in the active function area where the front left-door function block 31 is located is 6 times smaller than 7 times. The number of times accumulated by the count accumulator in the valid adjacent functional zone where the left back gate functional block 32 is located is 4 times less than 7 times. Therefore, the left front door functional block 31 is still confirmed as the active functional area, and then the step S70 of controlling the automobile 100 to execute the preset function corresponding to the functional area 31 can be implemented. For example, the automobile 100 performs unlocking of the left front door.

As shown in fig. 13, when the key 200 moves from fig. 12 to the position shown in fig. 13, the active function area before the key 200 is the left front door function block 31, and therefore, the left front door function block core area 312, the left front door function block transition area 311, and the left rear door transition area 321 form an active function area, which is equivalent to the left front door function block 31. The left back door core area 322 may become an active neighbor functional area equivalent to the left back door functional block 32. If the key 200 is in the left back door function block core area 322, the position of the key 200 is determined to be a normal distribution curve centered around the actual position of the key 200. At this time, the functional area 31 corresponding to the sliding window shift register set falls into 312 and 311 for 1 time and 321 for 1 time within 10 predetermined cycles, and the key 200 falls into the original active functional area 31 for 2 times; the bank of function blocks 32 sliding window shift registers confirms that the key 200 falls into the left back door function block 32 (i.e., the valid adjacent function block consisting of 322) 8 times within 10 predetermined number of cycles. At this time, the predetermined number of times is 7 times, and the number of times accumulated by the function region counting accumulator where the left back door function block 32 is located is 8 times greater than 7 times, so that the left back door function block 32 can be determined as a new active function region, and then the active function region is formed by (322 +321+ 311); the effective adjacent functional area is composed of 312; step S70 may be implemented to control the vehicle 100 to execute the preset function of the functional area 32 corresponding to the new active functional area. For example, the automobile 100 performs unlocking of the left rear door and unlocking of the left front door.

Thus, a value of the predetermined number of times greater than half of the value of the predetermined number of cycles may make the confirmation of the key 200 function area by the automobile 100 realistic.

Specifically, the value of the predetermined number of times is set to be greater than half of the value of the predetermined number of cycles, that is, the value of the predetermined number of times is 50% or more of the value of the predetermined number of cycles, and preferably, the value of the predetermined number of times may be 60% or more of the value of the predetermined number of cycles.

Referring to fig. 14, in some embodiments, the control method includes:

and S100, controlling the automobile 100 to stop executing the functions corresponding to the other functional areas under the condition that the automobile 100 executes the preset functions corresponding to the active functional areas.

In this way, the automobile 100 can be prevented from conflicting with functions performed by other function areas when the preset function of the active function area is performed.

Specifically, referring to the functional areas of the automobile 100 in fig. 3, when the controller 20 of the automobile 100 executes the control method and confirms that the active functional area is the unlock function of the front left door functional block 31, the automobile 100 stops controlling the functions executed by the functional areas other than the active functional area, such as the rear left door functional block 32, the front right door functional block 33, the rear right door functional block 34, the rear left door functional block 35, and the rear right door functional block 36.
