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

[0060] The embodiment provided in this application is an embodiment of a method for protecting a vehicle from rolling over.

[0061] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0062] Step S101, when the rollover parameter value of the vehicle detected on the time axis meets the preset start-up protection task condition, the ignition delay duration is calculated, and multiple types of monitoring parameter values ​​on the time axis are obtained based on the rollover parameter value on the time axis.

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

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

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

[0066] The ignition delay duration is calculated from the time point when the rollover parameter value of the vehicle is detected on the time axis to meet the preset start-up protection task conditions.

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

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

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

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

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

[0072] Step S101b-2: determine that the absolute value represents the monitoring parameter value.

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

[0074] In some specific embodiments, when the rollover parameter value of the vehicle detected on the time axis meets the preset start-up protection task condition, the ignition delay duration is calculated, and multiple types of monitoring parameter values ​​on the time axis are obtained based on the rollover parameter value on the time axis, including:

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

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

[0077] This specific embodiment performs integration processing on the roll parameter value.

[0078] For example, if the roll parameter value includes the roll angular velocity value ω_x, the full integral value The rolling angular velocity value ω_x is fully integrated from time point 0 to the current time point t, and the full integration is the result of energy accumulation; the moving window integral value ΔD = ∫ t t+len ω_x t , the rolling angular velocity value ω_x is dynamically integrated in a moving window (such as a preset length value len of the moving window), that is, the energy change.

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

[0080] In some specific embodiments, when the rollover parameter value of the vehicle detected on the time axis meets the preset start-up protection task condition, the ignition delay duration is calculated, and multiple types of monitoring parameter values ​​on the time axis are obtained based on the rollover parameter value on the time axis, including:

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

[0082] Step S101d-2: determine whether the weighted integral value represents the monitoring parameter value.

[0083] This specific embodiment performs weighted integration processing on the roll parameter value.

[0084] For example, if the roll parameter value includes the roll angular velocity value ω_x, the weighted integral value of the roll parameter value = |ω_x| xD, where D represents the full integral value; or the weighted integral value of the roll parameter value = |ω_x| xΔD, where ΔD represents the moving window integral value.

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

[0086] In some specific embodiments, when the rollover parameter value of the vehicle detected on the time axis meets the preset start-up protection task condition, the ignition delay duration is calculated, and multiple types of monitoring parameter values ​​on the time axis are obtained based on the rollover parameter value on the time axis, including:

[0087] Step S101e-1, when the rollover parameter value of the vehicle detected on the time axis meets the preset start-up protection task condition, the ignition delay time is calculated, and the rollover parameter value on the time axis is preprocessed.

[0088] Step S101e-2, obtaining multiple types of monitoring parameter values ​​on the time axis based on the preprocessed rollover parameter values ​​on the time axis.

[0089] In this specific embodiment, the preprocessing includes performing low-pass filtering and data normalization on the rollover parameter values ​​on the time axis.

[0090] Low-pass filtering can eliminate the sawtooth fluctuations in the rollover parameter value on the time axis, making the rollover parameter value curve on the time axis smoother and reducing abnormal data in the rollover parameter value curve. The filter level is set to 4 to 5.

[0091] Data normalization can reduce the distortion value in the rollover parameter value on the time axis, and limit the effective range of the rollover parameter value to [-128, 127] by compressing the rollover parameter value, thereby reducing the amount of data.

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

[0093] If the monitoring parameter value of the first type (i.e., the absolute value of the rolling parameter value) is greater than the preset first monitoring threshold of the corresponding type, that is, the curve crosses the straight line of the preset first monitoring threshold in the first monitoring coordinate system, then the 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, that is, the curve passes through the straight line of the preset second monitoring threshold in the second monitoring coordinate system, then the second type of crossing flag Flag2 is set;

[0095] If the third type of monitoring parameter value (ie, weighted integral value) is greater than the corresponding type of preset third monitoring threshold, ie, the curve passes through 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] Each type of crossing mark does not necessarily have to be set at the same time.

[0097] Step S103, when the plurality of types are all set with their own crossing flags, and when the ignition delay time is less than or equal to a preset ignition delay time threshold, an ignition instruction for the airbag associated with the rollover is generated.

[0098] For example, when the ignition delay duration is less than or equal to the preset ignition delay duration threshold, if the first type, the second type and the third type are all set with a crossing flag, the ignition condition for the airbag associated with the rollover is met, and an ignition instruction for the airbag associated with the rollover is generated.

[0099] When the ignition instruction is obtained and the ignition timing satisfies the ignition matrix, the airbag associated with the rollover is ignited, and the airbag associated with the rollover is activated to protect the occupant.

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

[0101] When the ignition delay time is longer than the preset ignition delay time threshold, and at least one type does not have a crossing mark set, the protection task is terminated.

[0102] In this specific embodiment, if not all types have their own crossing flags set within the preset ignition delay time threshold, it is determined that the ignition condition is not met and the protection task is terminated. The rollover parameter value of the vehicle is re-checked on the time axis to see if it meets the preset start protection task condition, and the next task is protected. Avoid misjudgment caused by long waiting.

[0103] When the embodiment of the present application detects that the rollover parameter value of the vehicle on the time axis meets the preset conditions for starting the protection task, the ignition delay duration is calculated, and multiple types of monitoring parameter values ​​on the time axis are obtained based on the rollover parameter value on the time axis; when the monitoring parameter value of any type on the time axis is greater than the preset monitoring threshold of the corresponding type, the crossing mark of the corresponding type is set; when the multiple types have all set their own crossing marks, when the ignition delay duration is less than or equal to the preset ignition delay duration threshold, an ignition instruction for the airbag associated with the rollover is generated. The ignition instruction for the airbag associated with the rollover is determined by identifying multiple features of the rollover parameter value on the time axis. This provides safe and reliable protection for the occupants when the vehicle rolls over, and improves the survival rate of the occupants.
