[0059] The optional embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] The embodiments provided by the present application are a vehicle rollover protection method.

[0061] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. Figure 1 The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] Step S101, when the rollover parameter value of the vehicle detected on the time axis satisfies the preset starting protection task condition, the ignition delay time length is calculated, and the monitoring parameter values of multiple types on the time axis are obtained based on the rollover parameter values on the time axis.

[0063] The rollover parameter value includes a rollover angular velocity value.

[0064] The roll angular velocity value is collected by an angle sensor arranged in the vehicle.

[0065] When the roll parameter value of the vehicle detected on the time axis meets the preset starting protection task condition, the protection task is started.

[0066] The ignition delay duration is calculated from the time point when the roll parameter value of the vehicle detected on the time axis meets the preset starting protection task condition.

[0067] In some embodiments, when the roll parameter value of the vehicle detected on the time axis meets the preset starting protection task condition, the ignition delay duration is calculated, and the monitoring parameter values of multiple types on the time axis are obtained based on the roll parameter value on the time axis, including:

[0068] In step S101a, when the roll parameter value of the vehicle detected on the time axis exceeds the preset safety parameter value range, the ignition delay duration is calculated, and the monitoring parameter values of multiple types on the time axis are obtained based on the roll parameter value on the time axis.

[0069] In this embodiment, when the roll parameter value on the time axis is within the preset safety parameter value range, the vehicle is safe. If the roll parameter value on the time axis exceeds the preset safety parameter value range, that is, the roll parameter value is less than the minimum threshold in the preset safety parameter value range, or the roll parameter value is greater than the maximum threshold in the preset safety parameter value range, the protection task is started.

[0070] In some embodiments, when the roll parameter value of the vehicle detected on the time axis meets the preset starting protection task condition, the ignition delay duration is calculated, and the monitoring parameter values of multiple types on the time axis are obtained based on the roll parameter value on the time axis, including:

[0071] In step S101b-1, when the roll parameter value of the vehicle detected on the time axis meets the preset starting protection task condition, the ignition delay duration is calculated, and the absolute value of the roll parameter value on the time axis is obtained based on the roll parameter value on the time axis.

[0072] In step S101b-2, it is determined that the absolute value represents the monitoring parameter value.

[0073] In this embodiment, the absolute value of the roll parameter value is taken as the first type of monitoring parameter value. If a first monitoring coordinate system is established, the time axis is taken as the first coordinate axis, and the absolute value of the roll parameter value is taken as the second coordinate axis, a curve is generated in the first monitoring coordinate system.

[0074] In some embodiments, when the roll parameter value of the vehicle detected on the time axis satisfies the preset starting protection task condition, the ignition delay duration is calculated, and the multiple types of monitoring parameter values on the time axis are obtained based on the roll parameter value on the time axis, including:

[0075] Step S101c-1, when the roll parameter value of the vehicle detected on the time axis satisfies the preset starting protection task condition, the ignition delay duration is calculated, and the full integral value or the moving window integral value of the roll parameter value on the time axis is obtained based on the roll parameter value on the time axis.

[0076] Step S101c-2, determining that the full integral value or the moving window integral value represents the monitoring parameter value.

[0077] In this embodiment, the roll parameter value is integrated.

[0078] For example, if the roll parameter value includes the roll angular velocity value ω x, the full integral value is The full integral of the roll angular velocity value ω x from the 0 time point to the current t time point is the result of energy accumulation; the moving window integral value is The dynamic integral of the roll angular velocity value ω x in the moving window (such as the preset length value len of the moving window) is the energy change amount.

[0079] In this embodiment, the full integral value or the moving window integral value of the roll parameter value is used as the second type of monitoring parameter value. If a second monitoring coordinate system is established, the time axis is the first coordinate axis, and the full integral value or the moving window integral value of the roll parameter value is the second coordinate axis, a curve is generated in the second monitoring coordinate system.

[0080] In some embodiments, when the roll parameter value of the vehicle detected on the time axis satisfies the preset starting protection task condition, the ignition delay duration is calculated, and the multiple types of monitoring parameter values on the time axis are obtained based on the roll parameter value on the time axis, including:

[0081] Step S101d-1, when the roll parameter value of the vehicle detected on the time axis satisfies the preset starting protection task condition, the ignition delay duration is calculated, and the weighted integral value of the roll parameter value on the time axis is obtained based on the roll parameter value on the time axis.

[0082] Step S101d-2, determining that the weighted integral value represents the monitoring parameter value.

[0083] In this embodiment, the roll parameter value is weighted and integrated.

[0084] For example, if the roll parameter value includes a roll angular velocity value ω x, the weighted integral value of the roll parameter value is = | ω x | × D, where D represents a full integral value; or the weighted integral value of the roll parameter value is = | ω x | × ΔD, where ΔD represents a moving window integral value.

[0085] In the embodiment, the weighted integral value of the roll parameter value is taken as a third type of monitoring parameter value. If a third monitoring coordinate system is established, with a time axis as a first coordinate axis and the weighted integral value of the roll parameter value as a second coordinate axis, a curve is generated in the third monitoring coordinate system.

[0086] In some embodiments, when the roll parameter value of the vehicle detected on the time axis satisfies a preset starting protection task condition, a firing delay duration is calculated, and multiple types of monitoring parameter values on the time axis are obtained based on the roll parameter value on the time axis, including:

[0087] Step S101e-1, when the roll parameter value of the vehicle detected on the time axis satisfies a preset starting protection task condition, a firing delay duration is calculated, and the roll parameter value on the time axis is preprocessed.

[0088] Step S101e-2, multiple types of monitoring parameter values on the time axis are obtained based on the preprocessed roll parameter value on the time axis.

[0089] In the embodiment, the preprocessing includes low-pass filtering processing and data normalization processing on the roll parameter value on the time axis.

[0090] The low-pass filtering processing can eliminate sawtooth fluctuations in the roll parameter value on the time axis, make the curve of the roll parameter value on the time axis smoother, and reduce abnormal data in the curve of the roll parameter value. The filtering level is set to 4-5.

[0091] The data normalization processing can reduce distortion values in the roll parameter value on the time axis, limit the effective range of the roll parameter value to [-128, 127] by compressing the roll parameter value, and thus reduce the data amount.

[0092] Step S102, when any type of monitoring parameter value on the time axis is greater than a preset monitoring threshold value of the corresponding type, a corresponding type of crossing flag is set.

[0093] If the first type of monitoring parameter value (i.e., the absolute value of the roll parameter value) is greater than a preset first monitoring threshold value of the corresponding type, i.e., the curve crosses a straight line of the preset first monitoring threshold value in the first monitoring coordinate system, a first type of crossing flag Flag1 is set.

[0094] If the second type of monitoring parameter value (i.e. the full integral value or the moving window integral value) is greater than the preset second monitoring threshold of the corresponding type, i.e. the curve crosses the straight line of the preset second monitoring threshold in the second monitoring coordinate system, the second type of crossing flag Flag2 is set;

[0095] If the third type of monitoring parameter value (i.e. the weighted integral value) is greater than the preset third monitoring threshold of the corresponding type, i.e. the curve crosses the straight line of the preset third monitoring threshold in the third monitoring coordinate system, the third type of crossing flag Flag3 is set.

[0096] The crossing flags of each type are not necessarily set at the same time.

[0097] When the plurality of types are set with the crossing flags of the respective types, when the ignition delay time length is less than or equal to the preset ignition delay time length threshold, an ignition instruction of the safety airbag associated with the roll is generated.

[0098] For example, when the ignition delay time length is less than or equal to the preset ignition delay time length threshold, if the crossing flags of the first type, the second type and the third type are all set, the ignition condition of the safety airbag associated with the roll is met, and the ignition instruction of the safety airbag associated with the roll is generated.

[0099] When the ignition instruction is obtained, when the ignition time meets the ignition matrix, the safety airbag associated with the roll is ignited, and the safety airbag associated with the roll is started to protect the occupant.

[0100] In some embodiments, the method further comprises:

[0101] When the ignition delay time length is greater than the preset ignition delay time length threshold, and at least one type does not set the crossing flag, the protection task is terminated.

[0102] In the present embodiment, if within the preset ignition delay time length threshold, not all types set the crossing flag of the respective type, it is determined that the ignition condition is not met, and the protection task is terminated. The roll parameter value of the vehicle is detected again on the time axis to determine whether the preset start protection task condition is met, and the next task is protected. Avoiding misjudgment caused by long waiting time.

[0103] The embodiment of the present application detects the roll parameter value of the vehicle on the time axis when the roll parameter value meets the preset starting protection task condition, calculates the ignition delay duration, and obtains the monitoring parameter values of multiple types on the time axis based on the roll parameter values on the time axis; when the monitoring parameter value of any type on the time axis is greater than the preset monitoring threshold value of the corresponding type, the penetration identifier of the corresponding type is set; when the penetration identifiers of the multiple types are all set, when the ignition delay duration is less than or equal to the preset ignition delay duration threshold value, the ignition instruction of the safety airbag associated with the roll is generated. The ignition instruction of the safety airbag associated with the roll is determined through the multiple feature recognitions of the roll parameter values on the time axis. Therefore, the safe and reliable protection is provided for the passengers when the vehicle rolls, and the survival rate of the passengers is improved.

[0104] The present application also provides a device embodiment for implementing the method steps of the above embodiments, based on the same explanation of the name meaning and the same technical effects as the above embodiments, which will not be repeated here.
