Background

At present, in the existing indexes for evaluating the vehicle handling characteristics, the roll stiffness is an evaluation index for measuring the lateral deflection amplitude between a vehicle body and a chassis when the vehicle turns. When the roll stiffness is small, the roll angle of the vehicle during turning is large, so that the comfort is better for passengers, but the vehicle is easy to turn over and lose control. When the roll stiffness is large, the roll angle of the vehicle during turning is small, the riding comfort is poor, but the vehicle control performance is improved, and the situation that the vehicle is out of control during turning is not easy to happen.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, including but not limited to combinations of embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any inventive step are within the scope of the present application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.

The invention conception of the application is as follows:

an active stabilizer bar is installed to a vehicle, that is, an actuator is provided at an end of the stabilizer bar connected to a suspension such that the end of the stabilizer bar moves up and down to change the position and posture of the stabilizer bar, or to generate a twisting moment, also called an anti-roll moment, to counteract a roll phenomenon generated when the vehicle turns. Meanwhile, a regulation application or a regulation program is correspondingly set for the execution mechanism, so that a user can directly regulate the regulation control on a vehicle-mounted interactive interface or on the regulation equipment at the mobile end, that is, the control parameters of the execution mechanism can be correspondingly regulated, and the rolling stiffness of the vehicle can be freely defined by the user within a preset range. For example, when the vehicle is loaded unevenly, and the vehicle is inclined in a single side or front and back direction, the user adjusts the roll stiffness of the vehicle to make the roll stiffness of the vehicle different between the left and right sides or front and back sides, so that the vehicle posture returns to normal. These can be achieved only by user-defined adjustment in real time according to the state of the vehicle, which cannot be measured during vehicle design.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic view of an application scenario of roll stiffness adjustment of a vehicle according to an embodiment of the present application. As shown in fig. 1, an active stabilizer 101 is provided on a front suspension and/or a rear suspension of a vehicle, and an actuator 102 is provided at a connection point of the active stabilizer 101 and any one of the suspension, the swing arm, and the vehicle body (in fig. 1, the case of connection with the suspension or the swing arm is shown). The actuator changes the position and state of the stabilizer bar 101 by moving up and down, and generates an anti-roll moment, thereby adjusting the roll rigidity of the vehicle. The actuator 102 may be of a pneumatic type or a hydraulic type, and the gas or liquid is compressed by a motor to move up and down.

The vehicle-mounted end is provided with an interactive interface 120, the mobile end is provided with a regulation application 110, and both the interactive interface and the mobile end can regulate and control the execution mechanism 102, so that the vehicle-mounted rigidity is regulated.

A front wheel roll stiffness adjustment control 121 and a rear wheel roll stiffness adjustment control 122 are provided on the interactive interface 120. The user can adjust the front/rear roll stiffness of the vehicle by adjusting the position of the slider on the adjusting control 121 or the adjusting control 122 or directly inputting a corresponding numerical value.

For the regulation application 110 on the movable end, an adjustment control 111 and an adjustment control 112 are also arranged on the regulation application 110, and the two controls can correspond to the front and rear transverse stabilizer bars and also can correspond to the roll stiffness of the left side and the right side, so that when a user finds that the vehicle rolls outside, the user directly slides the adjusting control 111 and/or the slider of the adjustment control 112 on the regulation application 110 through the movable end such as a mobile phone, and can realize the adjustment of the roll stiffness of the vehicle, so that the roll of the vehicle can be recovered, and the risk that the vehicle rolls over easily due to the uneven load of the vehicle can be overcome.

As can be seen from fig. 1, the roll stiffness adjusting method for a vehicle provided by the present application can be applied to a mobile terminal, a vehicle-mounted terminal, or a combination thereof, and the following description first describes a scenario applied to the mobile terminal in detail.

Fig. 2 is a schematic flow chart of a method for adjusting roll stiffness of a vehicle according to an embodiment of the present disclosure. As shown in fig. 2, in the present embodiment, the method for adjusting roll stiffness of a vehicle is mounted on a mobile terminal, such as a mobile phone, a tablet computer, a dedicated mobile adjusting device, and the specific steps include:

s201, responding to an operation instruction of a user on the adjusting control, and acquiring the current state of the adjusting control and the roll stiffness model.

In this step, the roll stiffness model corresponds to the current vehicle, with the adjustment controls on the current vehicle and/or the moving end.

In this embodiment, the adjustment control is disposed on the mobile terminal, and the adjustment control includes: at least one of an adjusting slider, a button and a numerical value input box on the interactive interface, wherein the current state comprises the following steps: the position of the sliding block in the preset range is adjusted.

Specifically, when a user checks a vehicle condition or finds that a vehicle load is unevenly distributed and has a left-right roll or a front-back roll when the vehicle is driven, the user may open a control application on a mobile terminal such as a mobile phone, and then slide an adjusting slider on an adjusting control in a touch manner on an interactive interface of the control application to enable the adjusting slider to be located at different positions within a preset range, or click an increase button or a decrease button to enable the position of the slider to be moved, or directly input a corresponding numerical value in a text box, and after the input, the slider correspondingly moves the position.

The position of the adjusting slider is obtained by the adjusting application, namely the current state of the adjusting control.

Meanwhile, the control application also needs to acquire a roll stiffness model corresponding to the current vehicle, such as a corresponding relation curve of a stroke and roll stiffness of a suspension when the vehicle rolls, so as to adjust the current vehicle, and the control application can adjust the roll stiffness of various different vehicles.

In this step, the actuator is used to adjust the attachment position and the operating state of the stabilizer bar on the vehicle on the suspension. And the regulation and control application of the movable end obtains the roll stiffness value corresponding to the position of the regulating slide block according to the mapping relation between the position of the slide block and the roll stiffness.

Fig. 3 is a schematic diagram of a relationship curve of a suspension stroke and a front wheel steering stiffness according to an embodiment of the present application. As shown in fig. 3, the user adjusts the shape and distribution of the current relationship curve in the area defined by the upper adjustment limit and the lower adjustment limit to change the roll stiffness corresponding to different suspension strokes, that is, the user determines each control parameter of the confidence mechanism by adjusting the current relationship curve of the actuator of the front-wheel stabilizer bar, so that when the vehicle rolls in a turn, the height sensor on the suspension detects different suspension strokes, and the corresponding adjustment actuator moves up and down, so that the front-wheel stabilizer bar generates the corresponding anti-roll moment to increase or decrease the roll stiffness of the vehicle.

Fig. 4 is a schematic diagram of a relationship curve of a suspension stroke and a rear wheel roll stiffness according to an embodiment of the present application. As shown in fig. 4, the user adjusts the shape and distribution of the current relationship curve in the area defined by the upper adjustment limit and the lower adjustment limit to change the roll stiffness corresponding to different suspension strokes, that is, the user determines each control parameter of the confidence mechanism by adjusting the current relationship curve of the actuator of the rear-wheel stabilizer bar, so that when the vehicle rolls in a turn, the height sensor on the suspension detects different suspension strokes, and the corresponding adjustment actuator moves up and down, so that the rear-wheel stabilizer bar generates the corresponding anti-roll moment to increase or decrease the roll stiffness of the vehicle.

And S203, sending control parameters to an actuating mechanism so that the transverse stabilizer bar generates a reverse roll moment meeting preset requirements on the vehicle.

In this step, the control application on the mobile terminal sends control parameters to the current chassis control system of the vehicle in a wireless or wired communication manner, so that the chassis control system controls the actuator according to the control parameters, and adjusts the position and state of the stabilizer bar, so that the stabilizer bar generates a roll moment that meets the user's requirements, thereby realizing the custom adjustment of the roll stiffness of the vehicle.

The technical problem of how to realize user-defined adjustment of the roll stiffness of the vehicle is solved. The technical effect that the roll stiffness of the vehicle can be directly self-defined and adjusted at any time according to the vehicle condition by a user through adjusting the control in or out of the vehicle is achieved.

Fig. 5 is a schematic flow chart of another vehicle roll stiffness adjusting method according to the present application. As shown in fig. 5, in the present embodiment, the method for adjusting roll stiffness of a vehicle is mounted in a chassis control system of a vehicle, and includes the following specific steps:

s501, acquiring a height value of the suspension relative to a preset reference position and an acceleration value in the height direction.

In this step, the chassis control system obtains the height value of the mechanical suspension relative to a preset reference position, such as the ground, and the acceleration value in the height direction from a height sensor and an acceleration sensor on the vehicle chassis or suspension.

Fig. 6 is a schematic structural diagram of a vehicle chassis control system according to an embodiment of the present application. The chassis control system takes a chassis control unit as a core, and controls an actuating mechanism of the front active stabilizer bar and an actuating mechanism of the rear active stabilizer bar to adjust the positions and the states of the front active stabilizer bar and the rear active stabilizer bar so as to generate anti-roll moment, thereby realizing the active adjustment effect on the roll stiffness of the mechanical suspension of the vehicle. The state of the mechanical suspension is detected by a height sensor and an acceleration sensor and fed back to a chassis control unit.

The chassis control unit feeds the roll state of the vehicle back to a user in real time through a vehicle-mounted interactive interface. Therefore, the user can self-define and adjust the roll stiffness of the vehicle through the adjusting control on the vehicle-mounted interactive interface.

And S502, determining the roll state of the vehicle according to the height value and the acceleration value.

In the present embodiment, the chassis control unit on the vehicle determines the roll state of the vehicle, such as whether the vehicle has left-right or front-rear roll when there is no vehicle turn at present, and whether the magnitude and acceleration of the left-right or front-rear roll coincide when the vehicle turns, based on the height value of the suspension and the acceleration value.

And S503, if the rolling state is greater than or equal to the preset rolling threshold value, outputting the rolling state and corresponding prompt information.

In this step, the prompt information is used to prompt the user to adjust the roll rigidity of the vehicle.

Specifically, when the vehicle state is found to be unbalanced, namely when the vehicle does not turn, the vehicle also rolls left and right or front and back, or when the vehicle turns, the left and right or front and back rolling amplitudes or accelerations of the vehicle do not accord with each other, namely the rolling state is greater than or equal to a preset rolling threshold value, early warning prompt information is output on the vehicle-mounted interactive interface.

And S504, responding to an operation instruction of the user on the adjusting control, and acquiring the current state of the adjusting control and the roll stiffness model.

In this step, the adjusting control comprises: at least one of an adjusting slider, a button and a numerical value input box on the interactive interface, wherein the current state comprises the following steps: adjusting the position of the sliding block in a preset range, inputting the current numerical value of the frame, increasing or decreasing the pressing times of the button and the like, wherein the interactive interface comprises: and the vehicle-mounted display screen and/or the display interface on the mobile communication equipment. In this embodiment, the interactive interface is an in-vehicle display screen.

And the roll stiffness model of the current vehicle stored in the memory of the chassis control unit is recalled.

In this step, the interactive interface further includes: the adjusting control is used for adjusting the shape of the corresponding relation curve in a range enclosed by the adjusting upper limit and the adjusting lower limit.

The roll stiffness model is a corresponding relation curve as shown in fig. 3 and 4, the shape of the corresponding relation curve is corrected by adjusting the current state of the control, and then the corrected corresponding relation curve is converted into corresponding control parameters, namely, data pairs of the suspension stroke and the roll stiffness identified by the sensor.

And S506, sending control parameters to an actuating mechanism so that the transverse stabilizer bar can generate a reverse roll moment meeting preset requirements on the vehicle.

In this embodiment, the data pair in the previous step is stored in the form of a data table, and when the chassis control unit receives the detection signal generated by the sensor, corresponding comparative analysis is performed, so as to obtain the control parameter corresponding to the actuator of the active stabilizer bar, and the control parameter is generated to the actuator, so that the rod end of the stabilizer bar moves up and down, and an anti-roll moment is generated, thereby realizing the customized adjustment of the roll stiffness of the vehicle.

And simultaneously, displaying in real time on an interactive interface of the vehicle, and displaying whether the adjusted vehicle suspension is still in a roll unbalance condition or not so as to enable a user to further adjust the vehicle suspension until the roll unbalance phenomenon caused by the uneven load of the vehicle is eliminated.
