Description

Roof adjusting system, vehicle body, vehicle, and roof adjusting method and device

Technical Field

The present application relates to the field of vehicles, and more particularly, to a roof adjustment system, a vehicle body, a vehicle, a method and an apparatus for adjusting a roof in a vehicle.

Background

With the motorization of vehicles, range anxiety has become a common state of mind for vehicle users. In addition to the electric energy consumed during the operation of the vehicle body electronic devices (such as an air conditioner, a lamp, an instrument panel, a controller, a central control screen and the like), overcoming the resistance during the running of the vehicle is another important factor of energy consumption. The running resistance of the vehicle mainly includes transmission resistance in the vehicle, ground resistance from the ground on which the vehicle runs, wind resistance during the running of the vehicle, and the like.

Generally, the wind resistance during the running of a vehicle can be divided into 3 types: (1) resistance to airflow striking the front of the vehicle; (2) frictional resistance generated by air passing through the vehicle body; (3) the exterior resistance of the vehicle. Wherein the drag created by the airflow striking the front of the vehicle may be reduced by reducing the frontal area of the vehicle. In the prior art, the frontal area of a vehicle is reduced by reducing the height of a chassis of a vehicle body and shielding tires of the vehicle so as to reduce the frontal area of the tires of the vehicle, thereby reducing the resistance generated by the air flow impacting the front of the vehicle.

However, according to the scheme of reducing the chassis height of the automobile body and shielding the tires of the automobile to reduce the resistance generated by the airflow impacting the front face of the automobile, the chassis height of the automobile body is reduced, so that the chassis of the automobile body of the automobile is easily scratched against the ground.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

For ease of understanding, terms referred to in the embodiments of the present application will be described below.

Firstly, frontal area: the projected area of the vehicle in the traveling direction, usually the air resistance, is proportional to the forward projected value of the frontal area of the vehicle.

In the body structure of the vehicle, the position and the shape of the ABC pillar relate to the overall arrangement, the safety and the driving comfort of the vehicle, and the ABC pillar not only plays a role in supporting the roof of a cab, but also plays an important role in protecting members in the cab.

Generally, a vehicle pillar includes an a-pillar, a B-pillar, a C-pillar, and a D-pillar. The pillar a (also called front pillar) refers to pillars on both sides of a windshield or in front of a front door of a vehicle. The B pillar (also called a center pillar) refers to a pillar between a front door of a vehicle and a rear door of the vehicle. The C-pillar (also called a rear pillar) refers to a pillar between the rear side of a rear door of a vehicle and a rear window of the vehicle. The D-pillar refers to a pillar between a small glass of the rear of the vehicle and a rear windshield of the vehicle.

It should be noted that cars have only a-pillar, B-pillar and C-pillar, and travel cars or Sport Utility Vehicles (SUVs) may also be provided with a D-pillar.

And thirdly, the running resistance of the vehicle.

In general,the running resistance of the vehicle can be represented by the formula: r_T＝R_M+R_E+R_WIs represented by the formula (I), wherein R_TRepresenting the total vehicle running resistance of the vehicle; r_MRepresents the transmission resistance of the vehicle, for example, the friction resistance of mechanical parts such as a transmission shaft, a speed reducer, an electrode and the like in the vehicle; r_EA ground resistance representing a ground on which the vehicle is running, for example, a frictional resistance of a tire of the vehicle with the ground, a rolling resistance of the tire of the vehicle itself; r_WIndicating the wind resistance during the travel of the vehicle.

The study shows that the longitudinal speed v of the vehicle is measured_xAt about 60km/h, the wind resistance R_WThe total vehicle running resistance R_T40% of; when the longitudinal speed v is_xAt about 120km/h, the wind resistance R_WThe total vehicle running resistance R_T65% of; when vx is approximately 160km/h, the wind resistance R_WThe total vehicle running resistance R_T85% of the total vehicle wind resistance, it can be seen that reducing the vehicle wind resistance is of great significance in reducing the vehicle total driving resistance to improve the vehicle's continuous mileage.

Wherein, the wind resistance R during the running of the vehicle_WCan be represented by formula

Wherein a represents the frontal area of the vehicle; c_wRepresenting a wind resistance coefficient of the vehicle; v. of_xIndicating the longitudinal speed of the vehicle. It can be seen from the above formula that the frontal area of the vehicle and the wind resistance coefficient of the vehicle are important factors influencing the wind resistance of the vehicle in the driving process. The above-mentioned wind resistance related to the frontal area is caused by the resistance generated by the airflow hitting the front face of the vehicle. The wind resistance associated with the frontal area is the resistance caused by the exterior of the vehicle. Fig. 1 shows the relationship between the exterior of the vehicle and the vacuum region, and based on fig. 1, it can be seen that when the exterior of the vehicle is not smooth enough, or the height of the trunk of the vehicle is high, the vacuum region behind the vehicle is increased, and the vacuum region is understood to be a region with lower air pressure relative to the surrounding region, and when the vacuum region is formed, the action exerted by the air pressure on the front and rear direction of the vehicleThe force is different in magnitude, and the air generates a backward average acting force on the vehicle, namely, the driving is hindered. The larger the vacuum area behind the vehicle, the greater the driving resistance of the vehicle.

At present, in order to adjust the wind resistance of a vehicle in the running process, the prior art adjusts the frontal area of the tires of the vehicle by adjusting the height of the chassis of the vehicle body or adjusts the height of the tail of the vehicle so as to adjust the size of a vacuum area behind the vehicle. The two solutions for reducing the wind resistance have respective limitations, for example, by reducing the frontal area of the vehicle tires, the resistance that can be reduced during the running of the vehicle is very limited. For another example, by reducing the height of the tail of the automobile, the crashworthiness of the automobile is reduced, and the driving safety is reduced while the wind resistance is reduced.

Therefore, in order to avoid the above problems, embodiments of the present application provide a solution for adjusting the windward area of the vehicle body to change the windage resistance of the vehicle during driving, that is, an adjustable roof is provided for the vehicle, and the windage resistance of the vehicle during driving is changed by adjusting the position of the roof relative to the vehicle body in the vehicle to adjust the windage area of the vehicle. The scheme of the embodiment of the present application is described below with reference to fig. 2.

Fig. 2 is a schematic diagram of a roof adjustment system according to an embodiment of the present application. The roof adjustment system 200 shown in fig. 2 includes a vehicle body 210, an adjustment mechanism 220, and a controller 230.

The vehicle body 210 includes a roof 211 and a body 212, and the roof 211 is connected to the body 212 by an adjustment mechanism 220.

The body 212 may be understood as a body portion of the vehicle body 210 other than the roof 211, and may include a body side 213, a body bottom, and the like.

Alternatively, the roof 211 is connected to the body 212 through the adjustment mechanism 220, and it is understood that the roof 211 is connected to the underbody through the adjustment mechanism 220, or the roof 211 is connected to the body side 213 through the adjustment mechanism 220, which is not limited in the embodiments of the present application. The roof 211 is coupled to the body side 213 via an adjustment mechanism 220. it is also understood that the roof 211 is coupled to the pillars of the body side 213 via the adjustment mechanism 220.

The adjusting mechanism 220 may be a rack and pinion adjusting mechanism, a worm and gear adjusting mechanism, a hydraulic adjusting mechanism, or a pneumatic adjusting mechanism, which is not particularly limited in the embodiments of the present application.

And the controller 230 controls the position of the roof 211 relative to the vehicle body 212 through the adjusting mechanism 220 so as to adjust the windward area of the vehicle.

The adjusting mechanism 220 may control the roof 211 to move up or down along a straight line relative to the body 212 to adjust the windward area of the vehicle, or the adjusting mechanism 220 may control the roof 211 to move up or down along an included angle relative to the body 212 to adjust the windward area of the vehicle, and the specific manner of adjusting the roof is not limited in the present application.

The controller 230 may be a controller including a driving device, for example, a controller in a vehicle controls the operating state of the adjustment mechanism 220 through the driving device. Wherein the controller may multiplex existing controllers in the vehicle, such as a Vehicle Control Unit (VCU). The controller may also be an independent controller, which is not limited in this embodiment of the present application. The driving device may be a hydraulic drive, a pneumatic drive, an electric drive, a mechanical drive, or the like.

As described above, the controller 230 may control the roof 211 to descend relative to the body 212 through the adjustment mechanism 220 to reduce the frontal area of the vehicle.

If the controller 230 controls the roof 211 to descend relative to the body 212 through the adjustment mechanism 220, the space in the vehicle cabin is reduced, the frontal area of the vehicle is reduced, and the resistance of the vehicle during traveling is reduced.

As described above, when the roof 211 is lowered relative to the body 212, the interior space of the cabin in the vehicle may be compressed, possibly degrading the user experience. Therefore, in order to enable the automobile to meet the requirements of various scenes, the controller 230 may further control the roof 211 to ascend relative to the body 212 through the adjusting mechanism 220, so as to increase the space in the cabin of the vehicle, which is beneficial to improving the user experience.

In general, the streamlined design of the exterior of the vehicle may reduce the area of the vacuum area behind the vehicle to some extent, and thus, in order to simplify the process of lifting and lowering the roof, the roof 211 may be lifted and lowered as a whole, that is, the exterior of the roof 211 may not be changed during the process of lifting and lowering the roof. Of course, if the above-mentioned factors for simplifying the process of lifting and lowering the roof are not considered, the shape of the roof may also be adjusted during the process of lifting and lowering the roof, which is not limited in the embodiments of the present application.

In the above example, the drive motor 231 is in forward transmission during the raising of the roof 211, and the drive motor 231 is in reverse transmission during the lowering of the roof 211. Of course, the driving motor 231 may be driven forward while the roof 211 is lowered, and the driving motor 231 may be driven backward while the roof 211 is raised. The embodiments of the present application do not limit this.

Since the roof 211 needs to be raised or lowered with respect to the body 212, the roof 211 and the pillars need to be movably connected so that the roof 211 can be raised or lowered. The movable connection may be in various specific manners, and the embodiment of the present application is not limited thereto. For example, the pillars include a recess 310, and the recess 310 is used for accommodating the lifting region 320 of the roof, and during the lifting process of the roof 211, the lifting region 320 extends out of the recess 310, so that the roof 211 and the pillars are sealed, or the vehicle does not form a gap due to the lifting of the roof 211. During the lowering of the roof 211, the lifting areas 320 retract into the recesses 310. For another example, the recess may be provided in the roof 211, and accordingly, the plurality of pillars may be provided with the lifting areas, and the lifting areas on the plurality of pillars may protrude from the recess when the roof 211 is lifted, and may be retracted into the recess when the roof 211 is lowered. Of course, the roof 211 and the pillars may be connected by a soft lifting area, and the roof 211 is assisted to ascend and descend relative to the vehicle body side 213 by contraction and extension of the soft lifting area. The following description will be made with reference to fig. 3 by taking an example in which a plurality of pillars include the recess 310 to accommodate the lifting/lowering area 320 of the roof 211.

The lifting area may be a part of the vehicle roof 211, and may be made of the same material as the vehicle roof 211, which is not limited in the embodiments of the present application.

The recessed portion may be understood as a hollow pillar to form the recessed portion, or a solid pillar, which is formed at the junction of the pillar and the roof 211 to accommodate the lifting region of the roof 211.

Fig. 3 is a schematic view of a connection relationship between a roof and a pillar in a vehicle according to an embodiment of the present application. It should be understood that the components of the roof adjustment system 300 shown in fig. 3 that function identically to the components of the roof adjustment system 200 are given the same reference numerals.

The roof adjustment system 300 is provided with an a-pillar 215, a B-pillar 216, a C-pillar 217, and a D-pillar 218 on the vehicle body side, and a recess 310a is provided on the a-pillar 215, a recess 310B is provided on the B-pillar 216, a recess 310C is provided on the C-pillar 217, and a recess 310D is provided on the D-pillar 218. The recess 310a is used for accommodating the lifting region 320a (see 301 in fig. 3) on the vehicle roof 211, the recess 310b is used for accommodating the lifting region 320b on the vehicle roof 211, the recess 310c is used for accommodating the lifting region 320c on the vehicle roof 211, and the recess 310d is used for accommodating the lifting region 320d (see 302 in fig. 3) on the vehicle roof 211.

During the lifting of the roof 211, the

lifting areas

320a, 320b, 320c, 320d on the roof 211 protrude from the

recesses

310a, 310b, 310c, 310d of the vehicle pillars, so that after the roof 211 is lifted, the roof 211 and the pillars are sealed by the lifting areas.

During the lowering of the roof 211, the

lifting areas

320a, 320b, 320c, 320d on the roof 211 are retracted into the

recesses

310a, 310b, 310c, 310d of the vehicle pillars, so that the roof 211 and the pillars are sealed by the lifting areas after the roof 211 is lowered.

Alternatively, if the adjusting mechanism 220 used in the roof adjusting system 300 shown in fig. 3 is the adjusting mechanism based on rack and pinion shown in fig. 2, the

first transmission gears

221a, 221b, 221c, 221d, 221e, 221f, 221g, 221h in the adjusting mechanism 220 may be located in the recessed

portions

310a, 310b, 310c, 310d of the vehicle pillar, and the

racks

222a, 222b, 222c, 222d, 222e, 222f, 222g, 222h engaged with the

first transmission gears

221a, 221b, 221c, 221d, 221e, 221f, 221g, 221h may extend out of the recessed portions to push the roof 221 to rise and retract into the recessed portions to pull the roof 221 to fall.

In order to improve the driving safety and prevent the vehicle roof 211 from falling down under the action of load (gravity) to cause accidents, the adjusting mechanism 220 may further have a self-locking function, and when the self-locking function is opened, the vehicle roof 211 cannot lift any more. For example, the adjusting mechanism of the worm gear and worm is self-locking. For another example, the adjusting mechanism for the rack and pinion realizes the self-locking function by additionally adding an element for realizing the self-locking function.

Considering the driving experience of the automobile user, the stroke of the window glass should be matched with the lifting of the roof 211, so that the window glass can be matched with the roof 211 after the roof 211 is lifted or lowered, and a closed space is formed in the cabin of the automobile. Of course, if the user experience is not considered, the stroke of the window glass can be not changed, so that the cost of refitting the automobile is reduced.

For the case that the window glass is matched with the roof 211, the vehicle may include a frameless window, the roof 211 is located at the upper limit position of the roof lifting stroke, and when the window glass of the frameless window is located at the upper limit position of the window lifting stroke, the cabin of the vehicle is in a closed state.

The lifting of the roof 211 may be controlled by the driver, for example, by a mechanical key or a virtual key input. The roof 211 may be raised or lowered by an Advanced Driving Assistance System (ADAS) in the vehicle, and this function is applied to the unmanned Driving mode.

Alternatively, the ADAS may control the roof 211 to be raised or lowered according to the posture (e.g., lying, sitting, etc.) of the driver or passenger, the vehicle speed, the trunk storage height, etc. of the vehicle interior.

The driver or ADAS control of the controller 230 may be achieved by two control switches, wherein the ADAS may control the ascending or descending of the roof 211 by sending a command to the controller 230 to control the connection of the contacts in the first control switch 410. The driver can control the ascending or descending of the roof 211 by the connection of the contacts in the second control switch 420 in the controller 230.

Alternatively, the ADAS may send the command to the Controller 230 based on a communication protocol of a Controller Area Network (CAN). Of course, the ADAS may also send a command to the controller 230 based on other communication protocols, which is not limited in this embodiment of the application.

It should be noted that the driving speed of the vehicle is only one of the factors that are used as a reference for the ADAS to adjust the roof 211, and of course, the ADAS may also adjust the roof 211 based on the environmental factors of the environment where the vehicle is located. For example, the ADAS may adjust the roof 211 based on the wind speed of the environment in which the vehicle is located. The ADAS may also adjust the roof 211 based on the space occupied by the user in the vehicle. For example, the ADAS may detect the sitting posture of the user, determine that the user is occupying a lower space, and may control the roof 211 to descend. For another example, the ADAS may detect a sitting posture of the user, and if it is determined that the space occupied by the user is relatively large, the roof 211 may be controlled to ascend.

During the process of descending the roof 211, collision with the window glass is possible, so that during the process of controlling the roof 211 to descend, the current position of the window glass in the window glass ascending and descending stroke can be considered, so as to avoid collision with the window glass during the process of descending the roof 211, so that the window glass is extruded and exploded, and unnecessary loss is caused.

The following description will be made for the lowering process of the roof 211 and the raising process of the roof 211, respectively.

In the process of descending the vehicle roof 211, the control and adjustment mechanism 220 drives the vehicle roof 211 to descend relative to the vehicle body 212 according to the vehicle roof adjustment instruction and the current position of the window glass in the vehicle in the window glass ascending and descending stroke, and the control and adjustment mechanism comprises: determining a first distance of a current position of a window glass in the vehicle relative to the roof 211; sending a window glass descending instruction to a body controller BCM of the vehicle, wherein the window glass descending instruction is used for indicating the BCM to control the window glass in the vehicle to descend; based on the roof adjustment instruction, the adjustment mechanism 220 is controlled to drive the roof 211 to descend relative to the body 212, wherein the position of the window glass in the descended vehicle is a first distance relative to the distance of the descended roof 211.

For convenience of understanding, the following describes a method for controlling the lifting and lowering of a vehicle roof in an embodiment of the present application with reference to fig. 11 and 12.

Fig. 11 is a flowchart of a control method for raising and lowering a roof according to an embodiment of the present application. The method shown in fig. 11 includes step S1110 and step S1120.

And S1110, controlling pattern recognition.

Among other things, the type of the current control mode may be identified by a BCM in the vehicle, in particular, whether the current control mode is the driver control mode or the ADAS control mode.

In one implementation, the BCM determines a control mode by the type of the input control switch, wherein if the driver presses or releases the driver mechanical button (also referred to as "second control switch 420"), it determines that the current control mode is the driver mode; if the currently input vehicle is in an automatic driving mode or the lift of the roof 211 is controlled by the ADAS controller, it is determined that the current control mode is the ADAS control mode.

It should be understood that the driver control mode or ADAS control mode may be specifically used and may be determined according to the control mode input by the driver.

Alternatively, the control mode and the control request may be output according to the control mode. Specifically, the BCM may input the control request to the motor via the ADAS switch, the control request including a roof up request and a roof down request.

And S1120, lifting or lowering the roof under different control modes.

And if the current mode is the driver mode and the current mode is the ascending request, executing the roof ascending operation in the driver mode. In the ascending operation execution process of a driver, the driving motor is matched with the BCM, and the BCM is used for controlling the plurality of window glasses on the side face of the vehicle body to adapt to the ascending and descending of the vehicle roof.

For example, the motor can also monitor whether instantaneous resistance is met or not in real time, so as to prevent the phenomenon that the vehicle roof is damaged due to the fact that obstacles are suddenly met in the process of rising the vehicle roof.

In one implementation, if the driver mode is currently in and the lowering request is made, the roof lowering operation in the driver mode is performed. The automobile body side face lifting control system comprises a motor, a BCM, a plurality of window glasses, a vehicle body side face lifting control device and a vehicle body side face lifting control device, wherein in the descending operation execution process of a driver, the motor is matched with the BCM, and the plurality of window glasses on the side face of the vehicle.

The driving motor 231 may also monitor whether instantaneous resistance is encountered in real time during the control of the descent of the roof 211, so as to prevent the phenomenon that the driver, passengers, trunk articles, or the like are pressed during the descent of the roof.

In one implementation, the lifting process in the ADAS mode is similar to the lifting operation in the driver control mode, and is not described herein again to avoid repetition. However, it should be understood that the roof lifting process in the ADAS control mode can avoid false triggering through the ADAS locking switch of the vehicle, so as to further ensure the safety of the vehicle.

Fig. 12 is a flowchart of a method for controlling the lowering of a roof in a driver control mode according to an embodiment of the present application. The method shown in fig. 12 includes steps S1210 to S1250.

S1210, recognizing that the down button is pressed.

In one implementation, when the control pattern recognition module detects that the driver presses the descending mechanical button, the descending request in the driver control mode can be recognized.

And S1220, the motor communicates with the BCM.

In one implementation, the motor communicates with the BCM to determine whether the BCM has a fault. If the BCM has a fault, the roof ascending request of the driver cannot be executed, so that the phenomenon that the window glass is squeezed in the roof descending process is prevented; if the BCM is not in fault, the position of the window glass is further determined.

And S1230, adjusting the position of the vehicle window to be matched with the target position of the lowered vehicle roof.

In one embodiment, it is determined whether the current position of each window pane is below a target lowered position of the roof. The target lowering position of the roof is the position where the roof is finally located after the roof is controlled to descend.

As an example, if the position of each window glass is not lower than the target position after the roof is lowered, the BCM may control each window to be lowered according to the target position after the roof is lowered so that each window position is lower than the target position after the roof is lowered.

As another example, if the position of each window glass is lower than the target position after the roof is lowered, the roof may be further controlled to be lowered to the target position.

And S1240, controlling the roof to descend to the target position.

In one implementation, the driver may close the driver control switch, and the motor is rotated in a specific direction by the current, and when the motor is rotated in the specific direction, the retractable structure may be controlled to be shortened, so that the roof is lowered. For convenience of description, it is assumed that in this case, when the motor rotates in the reverse direction, the roof can be lowered.

In an implementation manner, referring to fig. 6, the first driving wheel can be driven to rotate clockwise by forward rotation (clockwise rotation) of the motor, the first driving wheel further drives the second driving wheel to rotate clockwise through the driving belt, the gear structure on the second driving wheel also rotates clockwise along with the second driving wheel, when the gear structure is meshed with the bar gear, the bar gear is driven to move downwards, and because the end of the bar gear is connected with the roof, the roof moves downwards along with the bar gear, and finally the roof descends.

In one implementation mode, in the descending process of the top layer of the vehicle body, the motor can also monitor whether the top layer of the vehicle body meets instantaneous resistance or not in real time, and if the top layer of the vehicle body meets the instantaneous resistance, the descending process is stopped; if there is no instantaneous resistance, the top layer of the vehicle body is lowered to the target value. The process can prevent the driver, passengers or trunk articles from being squeezed during the descending process of the top layer of the vehicle body.
