[0026] The embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present invention will be described in detail below.

[0027] In the related art, for example, a seat control module, a high-precision map storage and call module, a storage memory module, a satellite dynamic positioning module, and an external communication module are used to monitor the data of the seat, and the movement of the seat is supplemented according to the detection data, so as to adjust the attitude of the vehicle.

[0028] However, by adopting the above method, the implementation process is relatively complex and the cost is relatively high.

[0029] Therefore, for the vehicle body stability control method according to the embodiment of the present invention, by acquiring the cab attitude information and the tilt angle of the vehicle, when the tilt degree meets the preset condition, it is considered that the cab attitude may need to be adjusted, and further, the inflation action and / or deflation action of the air spring of the cab are adjusted according to the cab attitude information, so as to realize the automatic control of the vehicle body stability, making the control of the vehicle body stability more intelligent and accurate, improving the stability of the vehicle body, the driving safety of users and the vehicle use experience, and with lower cost.

[0030] The following will be combined with Figure 1 and Figure 2 to describe the vehicle body stability control method according to the embodiment of the present invention.

[0031] As Figure 1As shown in the figure, it is a flowchart of a vehicle body stability control method according to an embodiment of the present invention. The vehicle body stability control method according to the embodiment of the present invention at least includes step S1 and step S2.

[0032] Step S1, obtain the cab attitude information and the tilt angle of the vehicle.

[0033] In the embodiment, the cab attitude information refers to the dynamic state parameters of the cab during the driving of the vehicle. For example, the pitch angle, roll angle, vertical vibration frequency, etc.; the tilt angle of the vehicle is the angle between the vehicle body and the horizontal plane when the vehicle is driving on the road; a body attitude sensor is added to the cab of the vehicle, and the body attitude sensor is used to obtain the cab attitude information to obtain the initial cab attitude information of the vehicle and prepare for subsequent attitude adjustment. A transmission ramp sensor is used to obtain the tilt angle of the vehicle to provide a basis for judging whether to adjust the cab attitude.

[0034] Step S2, when the tilt angle meets the preset condition, adjust the inflation action and / or deflation action of the air spring of the cab according to the cab attitude information.

[0035] In the embodiment, the preset condition is the condition for judging whether the vehicle is driving on a horizontal road surface. Among them, the horizontal road surface is not an absolutely horizontal road surface, and a certain range of errors is allowed; if the vehicle is on a non-horizontal road surface, the cab attitude of the vehicle remains unchanged; if the vehicle is on a horizontal road surface, further judge the driving condition of the vehicle and the tilt degree of the cab under the driving condition. When the tilt degree exceeds the adjustment critical value, it is necessary to adjust the inflation action and / or deflation action of the air spring of the cab to ensure the user's driving comfort. In this way, the automatic adjustment of the cab attitude is realized according to the cab attitude information in combination with other CAN (Controller Area Network) signals of the whole vehicle, improving the smoothness of the cab and the driving safety, and with a relatively low cost. Furthermore, the automatic control of the vehicle body stability is realized, making the control of the vehicle body stability more intelligent and accurate, and improving the vehicle body stability, the driving safety of the user and the driving experience.

[0036] According to the vehicle body stability control method of the embodiment of the present invention, by obtaining the cab attitude information and the tilt angle of the vehicle, when the tilt degree meets the preset condition, it is considered that the cab attitude may need to be adjusted. Further, the inflation action and / or deflation action of the air spring of the cab is adjusted according to the cab attitude information to realize the automatic control of the vehicle body stability, making the control of the vehicle body stability more intelligent and accurate, improving the vehicle body stability, the driving safety of the user and the driving experience, and with a relatively low cost.

[0037] In some embodiments, adjusting the inflation and / or deflation actions of the air springs of the cab according to the cab attitude information includes: when the forward tilt angle of the cab exceeds the forward tilt angle threshold, inflating the front air springs of the cab and controlling the deflation of the rear air springs of the cab.

[0038] In an embodiment, the forward tilt angle threshold is a critical value for determining whether to adjust the cab attitude, and can be set according to experimental calibration and requirements; when the forward tilt angle of the cab exceeds the forward tilt angle threshold, for example, when the vehicle performs an emergency braking operation while driving on a horizontal road surface, the cab will be in a forward tilt state. When the forward tilt angle of the cab exceeds the forward tilt angle threshold, it is considered that the attitude of the cab needs to be adjusted to ensure the driving comfort of the user. Therefore, the front air springs of the cab will be inflated and the rear air springs of the cab will be controlled to deflate. For example, the front air springs of the cab will be inflated and the rear air springs will be deflated to adjust the cab attitude, so that when the forward tilt angle of the vehicle exceeds the forward tilt threshold, the forward pitching of the vehicle during driving and braking can be reduced by adjusting the cab attitude, ensuring the vehicle use comfort of the user.

[0039] In some embodiments, adjusting the inflation and / or deflation actions of the air springs of the cab according to the cab attitude information includes: when the rear tilt angle of the cab exceeds the rear tilt angle threshold, deflating the front air springs of the cab and controlling the inflation of the rear air springs of the cab.

[0040] In an embodiment, the rear tilt angle threshold is a critical value for determining whether to adjust the cab attitude, and can be set according to experimental calibration and requirements; when the rear tilt angle of the cab exceeds the rear tilt angle threshold, for example, when the vehicle performs an emergency acceleration operation while driving on a horizontal road surface, the cab will be in a rear tilt state. When the rear tilt angle of the cab exceeds the rear tilt angle threshold, it is considered that the attitude of the cab needs to be adjusted to ensure the driving comfort of the user. Therefore, the front air springs of the cab will be deflated and the rear air springs of the cab will be controlled to inflate. For example, the front air springs of the cab will be deflated and the rear air springs will be inflated to adjust the cab attitude, so that when the rear tilt angle of the vehicle exceeds the rear tilt threshold, the rear pitching of the vehicle during driving and braking can be reduced by adjusting the cab attitude, ensuring the vehicle use comfort of the user.

[0041] In some embodiments, adjusting the inflation and / or deflation actions of the air springs of the cab according to the cab attitude information includes: when the left tilt angle of the cab exceeds the left tilt angle threshold, inflating the left air springs of the cab and controlling the deflation of the right air springs of the cab.

[0042] In an embodiment, the left tilt angle threshold is a critical value for determining whether to adjust the cab posture, which can be set according to experimental calibration and requirements; when the left tilt angle of the cab exceeds the left tilt angle threshold, for example, when the vehicle is driving on a horizontal road surface and the road surface on the left side of the vehicle is lower than the road surface on the right side of the vehicle, including when the left wheels of the vehicle drive into a pothole on the road surface, then the cab will be in a left-tilt state. When the left tilt angle of the cab exceeds the left tilt angle threshold, it is considered that the posture of the cab needs to be adjusted to ensure the driving comfort of the user. Therefore, the left air spring of the cab is inflated and the right air spring of the cab is controlled to deflate. For example, the left air spring of the cab is inflated and the right air spring is deflated to adjust the cab posture, so that when the left tilt angle of the vehicle exceeds the left tilt threshold, the left sway of the vehicle during driving and braking can be reduced by adjusting the cab posture, and the vehicle use comfort of the user is guaranteed.

[0043] In some embodiments, adjusting the inflation action and / or deflation action of the air spring of the cab according to the cab posture information includes: when the right tilt angle of the cab exceeds the right tilt angle threshold, deflating the left air spring of the cab and controlling the right air spring of the cab to inflate.

[0044] In an embodiment, the right tilt angle threshold is a critical value for determining whether to adjust the cab posture, which can be set according to experimental calibration and requirements; when the right tilt angle of the cab exceeds the right tilt angle threshold, for example, when the vehicle is driving on a horizontal road surface and the road surface on the right side of the vehicle is lower than the road surface on the left side of the vehicle, including when the right wheels of the vehicle drive into a pothole on the road surface, then the cab will be in a right-tilt state. When the right tilt angle of the cab exceeds the right tilt angle threshold, it is considered that the posture of the cab needs to be adjusted to ensure the driving comfort of the user. Therefore, the left air spring of the cab is deflated and the right air spring of the cab is controlled to inflate. For example, the left air spring of the cab is deflated and the right air spring is inflated to adjust the cab posture, so that when the right tilt angle of the vehicle exceeds the right tilt threshold, the right sway of the vehicle during driving and braking can be reduced by adjusting the cab posture, and the vehicle use comfort of the user is guaranteed.

[0045] In some embodiments, the tilt angle satisfies a preset condition, including: the tilt angle is equal to 0.

[0046] In an embodiment, the tilt angle satisfying the preset condition includes that the tilt angle is equal to 0. For example, the tilt angle of the vehicle is obtained through a transmission ramp sensor. When the tilt angle is equal to 0 (a certain error is allowed as required), it can be considered that the vehicle is driving on a horizontal road. By determining that the tilt angle is equal to 0, the working condition of the vehicle driving can be determined, preparing for adjusting the cab posture information.

[0047] In some embodiments, after obtaining the cab attitude information and the tilt angle of the vehicle, the following steps are further included: when the tilt angle does not meet the preset condition, the air springs are not adjusted or slightly adjusted. The slight adjustment includes: when the tilt angle is greater than 0 and greater than the first preset angle, the front air spring of the cab is inflated according to the first preset adjustment duration and the rear air spring of the cab is controlled to deflate; when the tilt angle is less than 0 and less than the second preset angle, the rear air spring of the cab is deflated according to the second preset adjustment duration and the front air spring of the cab is controlled to inflate.

[0048] In an embodiment, the first preset angle is a critical value determined according to requirements, experimental calibration, etc. for judging whether to adjust the cab attitude under the uphill working condition. For example, it is set to 7°; the second preset angle is a critical value determined according to requirements, experimental calibration, etc. for judging whether to adjust the cab attitude under the downhill working condition. For example, it is set to -7°; the first preset adjustment duration is the duration for adjusting the cab attitude under the uphill working condition determined according to requirements, experimental calibration, etc. For example, it is set to 1 s; the second preset adjustment duration is the duration for adjusting the cab attitude under the downhill working condition determined according to requirements, experimental calibration, etc. For example, it is set to 1 s.

[0049] When the tilt angle does not meet the preset condition, for example, when the tilt angle of the vehicle obtained by the transmission ramp sensor is not equal to 0, it can be considered that the vehicle is in the uphill or downhill working condition; when the vehicle is in the uphill or downhill working condition, according to requirements, it can be selected not to adjust the air springs or slightly adjust the air springs. Specifically, not adjusting the air springs, for example, the cab attitude sensor does not trigger the adjustment of the air springs, the cab attitude is not adjusted, and the original cab attitude of the vehicle in the uphill or downhill working condition is maintained unchanged; slightly adjusting the air springs, for example, when the tilt angle is greater than 0, it is considered that the vehicle is in the uphill working condition. If the tilt angle is greater than the first preset angle at this time, it is considered that the cab attitude needs to be adjusted, then the front air spring of the cab is inflated and the rear air spring of the cab is controlled to deflate, and the adjustment time lasts for the first preset adjustment duration. When the tilt angle is less than 0, it is considered that the vehicle is in the downhill working condition. If the tilt angle is less than the second preset angle at this time, it is considered that the cab attitude needs to be adjusted, then the front air spring of the cab is deflated and the rear air spring of the cab is controlled to inflate, and the adjustment time lasts for the second preset adjustment duration, so as to ensure the stability of the cab attitude of the vehicle in the uphill or downhill working condition.

[0050] The following refers to Figure 2 Specifically describe the control method of the vehicle according to the embodiments of the present invention.

[0051] As Figure 2As shown, it is a flowchart of a vehicle body stability control method for another vehicle according to an embodiment of the present invention. The vehicle body stability control method of the embodiment of the present invention at least includes steps S10 - S23.

[0052] Step S10, obtain the cab attitude information and the tilt angle of the vehicle.

[0053] Step S11, determine whether the tilt angle is equal to 0. If so, execute step S13; otherwise, execute step S12.

[0054] Step S12, do not adjust the air spring or perform a micro - adjustment on the air spring. Step S13, adjust the inflation action and / or deflation action of the air spring of the cab according to the cab attitude information.

[0055] Step S14, the forward tilt angle of the cab exceeds the forward tilt angle threshold.

[0056] Step S15, adjust the front air spring of the cab to inflate and control the rear air spring of the cab to deflate.

[0057] Step S16, the rearward tilt angle of the cab exceeds the rearward tilt angle threshold.

[0058] Step S17, adjust the front air spring of the cab to deflate and control the rear air spring of the cab to inflate.

[0059] Step S18, the left - hand tilt angle of the cab exceeds the left - hand tilt angle threshold.

[0060] Step S19, adjust the left air spring of the cab to inflate and control the right air spring of the cab to deflate.

[0061] Step S20, the left - hand tilt angle of the cab exceeds the left - hand tilt angle threshold.

[0062] Step S21, adjust the left air spring of the cab to inflate and control the right air spring of the cab to deflate.

[0063] Step S22, the right - hand tilt angle of the cab exceeds the right - hand tilt angle threshold.

[0064] Step S23, adjust the left air spring of the cab to deflate and control the right air spring of the cab to inflate.

[0065] According to the vehicle body stability control method of the embodiment of the present invention, by obtaining the cab attitude information and the tilt angle of the vehicle, when the tilt degree meets the preset conditions, it is considered that the cab attitude may need to be adjusted. Further, according to the cab attitude information, the inflation action and / or deflation action of the air spring of the cab are adjusted to realize the automatic control of the vehicle body stability, making the control of the vehicle body stability more intelligent and accurate, improving the vehicle body stability, the driving safety of users and the vehicle use experience, and having a lower cost.
