[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0057] Referring to Figures 1 to 6 Fig. 1, according to the first aspect of the present application, an adjusting device 100 is provided, which is suitable for adjusting the gap between a steering pinion and a steering rack 200 in a vehicle 1, and the adjusting device 100 comprises an actuator 110 and a detector 120.

[0058] Specifically, the actuator 110 is configured to at least drive the steering rack 200 to approach the steering pinion; and the detector 120 is configured to at least detect the operation of the actuator 110, so that the adjusting device 100 can obtain the gap data between the steering pinion and the steering rack 200.

[0059] With the above scheme, the gap between the steering gear and the steering rack 200 can be dynamically detected or adjusted, so as to avoid problems caused by the mismatch between the gap and the driving state of the vehicle 1. For example, when the detector 120 detects that the gap is too large, the user can be reminded in time to perform maintenance.

[0060] With reference to Figures 1 to 6 In some embodiments of the present application, the adjusting device 100 comprises a controller 130.

[0061] The controller 130 is configured to at least control the operation of the actuator 110, so that the actuator 110 is at least in a preset working mode.

[0062] Specifically, the preset working mode of the actuator 110 comprises a detection mode, a suppression mode and a locking mode.

[0063] The detection mode is used to detect the gap between the steering gear and the steering rack 200; the suppression mode is used to suppress the jitter of the steering assembly by controlling the change range of the gap between the steering gear and the steering rack 200; and the locking mode is used to realize the direction locking function of the vehicle 1, i.e. to lock the steering rack 200, so as to prevent the vehicle 1 from being stolen.

[0064] With reference to Figures 1 to 6 The actuator 110 comprises an execution member 111, which can slide along a first axis 111a under the drive of a power assembly (not shown in the figure) in the actuator 110. The first axis 111a can be perpendicular to a second axis 200a of the steering rack, and the steering rack is arranged to move along the second axis 200a (a slight shift in the movement direction may be generated when the steering rack jitters).

[0065] That is, the execution member 111 is configured to at least move along a first direction, which is perpendicular to the movement direction of the steering rack 200.

[0066] The power assembly of the actuator 110 can be a prime mover based on electromagnetic induction or a pressure actuator (such as a hydraulic or pneumatic actuator), which only needs to translate the execution member 111. For those skilled in the art, the implementation scheme of the power assembly can be selected according to the actual situation, which will not be described here.

[0067] For the convenience of description, as an optional scheme, the power assembly can comprise a motor and a screw nut mechanism, the screw nut mechanism converts the rotation of the motor into translation through the threaded transmission of the screw rod and the nut, and the execution member 111 can be connected to or formed in the nut of the screw nut mechanism.

[0068] With reference to Figures 4 to 6As a more specific solution, the actuator 110 further comprises a non-working state, i.e. a non-activated state without power supply.

[0069] Referring to Figures 4 to 6 As shown, in some embodiments of the present application, the actuator 110 has a first working stroke when the actuator 110 is in the detection mode; the actuator 110 has a second working stroke when the actuator 110 is in the suppression mode; the actuator 110 has a third working stroke when the actuator 110 is in the locking mode.

[0070] It can be considered that Figure 5 The state of the actuating member 111 shown corresponds to the suppression mode, while Figure 6 The state of the actuating member 111 shown corresponds to the locking mode.

[0071] As a more specific solution, in the present application, the actuating member 111 is configured to apply a force to the steering rack 200, and as a specific solution, the actuating member 111 can apply the force in a manner of directly contacting the steering rack.

[0072] Specifically, the side of the steering rack 200 close to the actuator 110 is provided with a locking structure 202 that can be contacted by the actuator 110 to limit the movement of the steering rack 200; the side of the steering rack 200 close to the actuator 110 is provided with a contact surface 201, and the locking structure 202 is configured as a locking groove provided on the contact surface 201. The actuating member 111 can realize the detection mode and the suppression mode by contacting the contact surface 201, and thus embed the locking structure 202 to realize the locking mode.

[0073] In the process of approaching to contact the steering rack 200, the actuating member 111 does not have resistance, so the operating load of the actuator 110 is relatively stable, and without considering air resistance, it can be considered that there is no load, so the detector 120 can know whether the actuating member 111 contacts the steering rack 200 through parameters related to the load of the actuator 110 (such as current, resistance, power, etc.).

[0074] When the actuator 110 contacts the steering rack 200 and further pushes the steering rack 200 to the steering gear, the running load of the actuator 110 becomes larger and larger due to the resistance of the steering rack 200 and the constraint of the steering rack 200 itself, and reaches a peak when the steering rack 200 moves to the limit position (the limit position of engaging with the steering gear). Since there is a significant load fluctuation when the actuator 110 just contacts the steering rack 200, and the load reaches a peak at the limit position, the two nodes can be detected by the fluctuation of the parameters (such as current, resistance, power, etc.) related to the load of the actuator 110. It can be understood that, when the actuator 110 just contacts the steering rack 200, that is, the natural position of the steering rack 200, the gap between the steering gear and the steering rack 200 can be defined as the natural gap, that is, the gap without any external force; and at the limit position, it can be considered as the limit gap or the zero point (determined by the hardware structure) without gap; therefore, as long as the displacement between the two nodes is obtained, the natural position of the steering rack 200 can be obtained, that is, the natural gap can be obtained.

[0075] Therefore, in some embodiments of the present application, the detector 120 is at least configured to detect the load change and the movement stroke of the actuator 110.

[0076] The detector 120 can include a current detection module and a position detection module to realize the detection of the load and the position. The current detection module can be a sampling resistor, and the specific signal analysis can be realized by the controller 130, but it can still be considered that the detection is performed by the detector 120; the position detection module can adopt a position switch or a horizontal encoder or other position sensor.

[0077] It should be noted that the above detection of the load change of the actuator 110 can be indirect detection by parameters such as current, resistance, power, etc. which can be associated with the load change.

[0078] As an optional solution, the detector 120 is at least configured to detect the force and the movement stroke of the actuator 110. For example, a pressure patch or the like can be used to directly detect the pressure on the end of the actuator 111 to reflect whether the actuator 111 reaches the above-mentioned nodes.

[0079] Referring to Figures 4 to 6 Based on the above, in some embodiments of the present application, the first working stroke is greater than or equal to the second working stroke, that is, the movement stroke of the actuator 111 in the detection mode is greater than the movement stroke of the actuator 111 in the suppression mode, because the suppression mode does not necessarily press the steering rack to the limit position.

[0080] Similarly, the second movement stroke is less than or equal to the third working stroke, that is, the lock mode needs a larger stroke because the actuator 111 needs to be embedded into the lock structure 202.

[0081] In some embodiments of the present application, the first working stroke of the actuator 110 is configured to be dynamically adjusted based on the detection result of the detector 120; this is because the rotating gear and the rotating rack may have wear, so the stroke of the actuator 110 in the detection mode needs to be adjusted according to the feedback of the detector 120.

[0082] In some embodiments of the present application, the second working stroke of the actuator 110 is configured to be dynamically adjusted based on the detection result of the detector 120; this is because the natural gap may change, so the suppression mode needs to obtain a better suppression effect and also needs to be adjusted according to the change of the natural gap.

[0083] In some embodiments of the present application, the third working stroke of the actuator 110 is configured to be dynamically adjusted based on the detection result of the detector 120; similarly, because of the change of the natural gap, the lock mode needs to be effectively embedded into the lock structure 202 according to the actual position of the rotating rack to ensure the effectiveness of the lock.

[0084] According to a third aspect of the present application, the present application also provides a steering assembly (not shown in the figure), which comprises the above-mentioned adjusting device 100 or the steering gear 10.

[0085] Referring to Figure 7 The present application provides a specific control method of the above-mentioned adjusting device 100, mainly comprising the following steps:

[0086] S101: the vehicle 1 is powered on, that is, the electronic control system of the vehicle 1 starts to start; go to step S102.

[0087] S102: judge whether the vehicle 1 is running, if yes, go to step S103; if not, go to step S107.

[0088] S103: judge whether the signal of detecting each detection parameter of the vehicle 1 is normal, if yes, go to step S104; if not, go to step S106. Here, each detection parameter includes but is not limited to the lateral reference quantity (steering angle, steering angular velocity, yaw rate, lateral acceleration) of the vehicle 1, the longitudinal reference quantity (vehicle speed, longitudinal acceleration) and the current hand force torque, the vehicle 1 power-on information, etc.

[0089] S104: judge whether the condition of starting the suppression mode is met according to each detection parameter, if yes, go to step S105, if not, go to step S102.

[0093] S108: determining whether the user has turned on the gap detection function; if yes, go to step S109; if no, go to step S106.

[0094] S109: determining whether the vehicle 1 currently meets the detection condition (such as gap detection); if yes, go to step S110; if no, go to step S106.

[0095] S110: running the detection mode. Step S110 is a manual detection triggered by the user setting.

[0096] S111: running the detection mode, which is different from step S110, step S111 is an automatic detection triggered by the system. The automatic detection can improve the detection convenience, avoid the user forgetting to detect, and help to find the problem of the vehicle 1 in time.

[0097] S112: running the locking mode. The vehicle 1 is locked.

[0098] From the above, the present application can integrate gap detection and locking into the user's daily parking process through manual and automatic modes, so that the technical solution of the present application can trigger gap detection according to the needs or timing after the vehicle 1 is shipped.

[0099] Referring to Figure 8 As shown in the adjustment device provided by the present application, the specific control method for realizing the suppression mode includes the following steps:

[0100] S201: obtaining the driving data of the vehicle 1, which can include the steering wheel angle, speed, hand torque, vehicle speed, yaw rate, lateral acceleration, etc. of the vehicle 1; go to step S202.

[0101] S202: determining whether the conditions for starting the suppression mode are met according to each detection parameter; if yes, go to step S203; if no, go to step S207.

[0102] S203: starting the suppression mode; go to step S204.

[0103] S204: powering on the actuator 110, and the actuator 110 moves the execution member 111 to approach the steering rack 200; go to step S205.

[0104] S205: judge whether the actuator 110 is at the end of stroke, i.e. whether the execution member 111 reaches the suppression position, which is generally the position where the execution member 111 just contacts the steering rack 200 in the natural clearance state; if yes, go to step S206; if no, go to step S204.

[0105] S207: close the suppression mode.

[0106] Referring to Figure 9 As shown in the adjustment device provided in the present application, the specific control method for realizing the detection mode comprises the following steps:

[0107] S301: obtain the driving data of the vehicle 1, which can include the steering wheel angle, the rotation speed, the steering torque, the vehicle speed, the yaw rate, the lateral acceleration and the like of the vehicle 1; go to step S302.

[0108] S302: judge whether the vehicle 1 is in a stationary state; if yes, go to step S303; if no, go to step S312.

[0109] S303: judge whether the vehicle 1 is powered off (is starting to be powered off, rather than being powered off completely), i.e. the electric control system of the vehicle 1 starts to be closed; if no, go to step S304; if yes, go to step S306.

[0110] S304: judge whether the user has turned on the clearance detection function; if yes, go to step S305; if no, go to step S312.

[0111] S305: judge whether the vehicle 1 meets the detection condition; if yes, go to step S306; if no, go to step S312.

[0112] S306: start the detection mode, and then go to step S307.

[0113] S307: power on the actuator 110, and the actuator 110 acts to make the execution member 111 approach the steering rack 200, and go to step S308.

[0114] S308: obtain the clearance data, specifically, obtain the clearance data according to the actuator 110 load-related data and the stroke data; go to step S309.

[0115] S309: judge whether the clearance data meets the requirement; if yes, go to step S311; if no, go to step S310.

[0116] S310: outputting alarm information to inform the user of the abnormality of the gap data and the like, prompting the user to perform maintenance or repair, and the output of the alarm information can be performed through a human-computer interaction interface such as a central control, and the process proceeds to step S311.

[0117] S311: completion.

[0118] S312: closing the detection mode.

[0119] Referring to Figure 10 As a specific control method for realizing the locking mode in the adjustment device provided by the present application, the method includes the following steps:

[0120] S401: the vehicle 1 is powered off, and the process proceeds to step S402.

[0121] S402: the locking mode is run, and the process proceeds to step S403.

[0122] S403: the actuator 110 is actuated to embed the execution member 111 into the locking structure 202 (embedded to the bottom), and the process proceeds to step S404.

[0123] It should be noted that when the vehicle 1 is parked, the steering wheel may not necessarily be reset, and therefore the steering rack 200 may not necessarily be reset, so multiple locking structures 202 can be provided to correspond to the execution member 111 at multiple positions, and then a small range of reset can be performed within a certain distance range, such as slightly rotating the steering wheel by a hand feeling motor or the like, so that the locking position can correspond to the position of the execution member 111.

[0124] S404: completion.

[0125] Based on the above, the suppression function of the present application can be based on the detection function, that is, after detecting the natural gap (detecting the current position of the steering rack 200), the execution member 111 is moved to a position in contact with the steering rack 200 to suppress the shaking thereof, and similarly, the locking function also needs to be determined according to the gap data to be effectively embedded into the locking structure 202.

[0126] According to a fourth aspect of the present application, based on the above specific structure and control flow, the present application further provides a control method, referring to Figure 11 As the control method of the adjustment device provided by the present application, the method can mainly include:

[0127] S1: driving the steering gear and / or the steering rack 200 according to the gap between the steering gear and the steering rack 200, so that the gap between the steering gear and the steering rack 200 meets a predetermined condition.

[0128] As a more specific solution, step S1 can further include the following steps:

[0129] S10: detecting a natural position (or initial position) of the steering rack 200 according to a load change and a stroke change of the actuator 110 when driving the steering rack 200;

[0130] S20: controlling the actuator 110 to be in a preset working state according to the natural position of the steering rack 200.
