< method examples >

The vehicle is provided with a sensing module for monitoring the motion state of the vehicle. For example, a sensor module is provided in a vehicle lock, which can be used to monitor the movement state of the vehicle.

In one example, the sensing module includes an acceleration sensor, which may be a three-axis acceleration sensor. In one example, the sensing module may include a tilt sensor, which may be a three-axis tilt sensor. In one example, the sensing module may include a gyroscope. The gyroscope may be a three-axis gyroscope including three-axis angular rate sensors. The gyroscope may also be a six-axis gyroscope or a nine-axis gyroscope. The six-axis gyroscope comprises a three-axis acceleration sensor and a three-axis angular velocity sensor. The nine-axis gyroscope comprises a three-axis acceleration sensor, a three-axis angular velocity sensor and a three-axis magnetometer. In one example, the sensing module is provided with a processing module loaded with an attitude algorithm, and is used for performing fusion calculation on a plurality of sensing data measured by the sensing module to determine the attitude of the vehicle. In one example, the gyroscope is provided with a processing module loaded with an attitude algorithm, and the processing module is used for performing fusion calculation on multiple sensing data measured by the gyroscope to determine the attitude of the vehicle.

Referring to fig. 2, embodiments of the present disclosure provide a method of monitoring a vehicle. In one example, the method may be carried out by a monitoring device provided on the vehicle, which may be a vehicle lock, for example. The method may comprise steps S202-S206.

And S202, acquiring data output by the sensing module. The sensing module is arranged on the vehicle (such as a vehicle lock) and used for monitoring the motion state of the vehicle.

In the embodiment of the present disclosure, the data output by the sensing module includes the sensing data measured by the sensing module. For example, for an acceleration sensor, the sensory data may include acceleration. For a tilt sensor, the sensory data may include tilt. For example, for a nine-axis gyroscope, the sensing data may include acceleration, angular velocity, magnetic strength, euler angles, and quaternions. The sensory data output by the sensing module may include gesture-related data.

In the embodiment of the present disclosure, the data output by the sensing module may further include an interrupt signal output by each sensor. For example, the acceleration sensor is configured to output an interrupt signal when the acceleration value (i.e., the magnitude of the acceleration) is greater than an interrupt threshold value.

In one example, the sensing module performs sensing according to a preset sensing frequency (corresponding to a sensing period) to obtain sensing data. In one example, the sensing module reports the sensing data to the monitoring device according to a preset sampling frequency (corresponding to a sampling period), that is, the sensing module does not report all the sensing data to the monitoring device, but reports part of the sensing data to the monitoring device in a sampling manner. The detection frequency is usually higher than the sampling frequency, for example, the detection frequency can reach 1ms for sampling 1 time, and the sampling frequency can reach 25ms to 200ms for reporting once.

And step S204, determining whether the vehicle has preset abnormal motion during the locking period according to the data.

In one example of the present disclosure, the preset abnormal motion may be a free-fall motion, a violent vibration, a toppling, a tumbling motion.

In one example of the present disclosure, regarding the free-fall movement of the vehicle, when the free-fall time thereof exceeds a preset time period or the falling distance of the free-fall exceeds a preset falling distance, it is regarded that the abnormal movement of the vehicle has occurred. The longer time of the free-fall behavior of the vehicle or the longer falling distance indicates that the free-fall behavior of the vehicle is more likely to be caused by artificial violence.

In one example, during the locking of the vehicle, if any one or more of violent vibration, toppling, rolling motion, free-fall motion over a preset period of time, or over a preset fall distance occurs, it may be determined that the vehicle has undergone a preset abnormal motion during the locking.

In one example, determining whether a predetermined abnormal motion of the vehicle occurs during the locking period based on the data includes at least one of steps S302-308:

and S302, determining whether the vehicle moves freely in a period exceeding a preset time or a preset falling distance during locking according to the data.

When a person throws a vehicle under a bridge, into a river, or when an operator treats the vehicle with rough handling, rough unloading (e.g., throwing the vehicle off a truck), the vehicle may fall from a height during which there is some period of free fall behavior.

In one example, the preset duration may be set according to an application scenario. For example, the preset time period may be 0.5 s. And when the acceleration value of each sampling period of a plurality of continuous sampling periods (the total time length of the plurality of continuous sampling periods is greater than the preset time length) acquired by the detection device is less than the first acceleration threshold value, determining that the vehicle has the free-falling body movement exceeding the preset time length. For example, the first acceleration threshold is, for example, 0.1G, where G is the acceleration of gravity.

In one example, the preset falling distance may be set according to an application scenario. For example, the preset falling distance may be 1m or 2 m. And when the acceleration value of each sampling period of a plurality of continuous sampling periods acquired by the detection device is smaller than a preset first acceleration threshold value and the total falling distance in the plurality of continuous periods is calculated to exceed the preset falling distance, determining that the vehicle has free falling body movement exceeding the preset falling distance.

And step S304, determining whether the vehicle vibrates violently during the locking period according to the data.

When a person intentionally damages the vehicle or when an operator treats the vehicle in a rough handling and rough unloading mode, the vehicle is violently impacted, and violent vibration occurs. In this embodiment, what vibration is regarded as a violent vibration is preset based on the sensed data. Four examples are described below.

Example one: the monitoring device obtains very large acceleration and judges that the vehicle has violent vibration.

For example, when the acceleration value of the vehicle is greater than a preset second acceleration threshold value, it is determined that the vehicle has been severely vibrated. For example, the second acceleration threshold is, for example, 14G, where G is the acceleration of gravity.

Example two: the monitoring device determines whether the vehicle is severely vibrated based on the standard deviation detection.

The acceleration vector is measured in advance when the vehicle is normally placed as a standard acceleration vector. And after acquiring the acceleration output by the sensing module, the monitoring device performs vector subtraction with the standard acceleration vector to obtain a difference vector. And calculating the standard deviation of the module values of the difference value vectors corresponding to a plurality of continuous sampling periods, and determining that the vehicle has predefined violent vibration if the standard deviation is greater than a preset standard deviation threshold value.

For example, the sampling period is 100ms, i.e., the monitoring device acquires acceleration, 000.1G units of acceleration, every 100 ms. If the calculated standard deviation is greater than 80 for 50 consecutive sampling periods and greater than 200 for the next 100 consecutive sampling periods, then a severe vibration is deemed to have occurred.

Example three: the monitoring device determines whether the vehicle is severely vibrated based on the difference detection.

And after the monitoring device obtains the acceleration, calculating the accelerations of two continuous sampling periods to carry out vector subtraction to obtain a difference vector. In case of severe vibration, the direction of acceleration will change greatly, and the vector subtraction is mainly performed to calculate the direction change of acceleration.

In one specific example, if the modulus of the difference vector is greater than a preset difference threshold, it is determined that the vehicle is experiencing severe vibration.

In a specific example, if the module value of the difference vector is greater than a preset difference threshold and the acceleration value of any one of the two sampling periods is greater than a preset third acceleration threshold, it is determined that the vehicle has undergone a severe vibration. This approach is more suitable for detecting an artificially horizontal impact on a vehicle. For example, the third acceleration threshold is, for example, 5G, where G is the acceleration of gravity.

Example four: and the monitoring device determines that the vehicle has violent vibration when receiving the interrupt signal. For example, the interrupt threshold value of the acceleration sensor is set to a relatively large value, and when the acceleration value in any one axis direction detected by the three-axis acceleration sensor is larger than the interrupt threshold value, an interrupt signal is sent to the monitoring device, and the monitoring device confirms that the vehicle has been severely vibrated. The interrupt threshold is, for example, 14G, and when the acceleration value measured by the acceleration sensor is greater than 14G, an interrupt signal is issued.

The frequency of reading the sensing data of the sensing module by the monitoring device is limited, and generally does not exceed 50Hz under the existing software and hardware conditions, so that the monitoring device may not read the acceleration at the moment of impact or cannot read the acceleration value at the time of the acceleration peak. The detection frequency of the acceleration sensor is very fast and may exceed 1000Hz, and in the fourth example, the vehicle is determined to be in violent vibration by using the interruption behavior of the sensor, so that the condition that the violent vibration is generated due to missed detection can be avoided.

And S306, determining whether the vehicle topples over during the locking period according to the data.

When a person intentionally damages the vehicle or when an operator treats the vehicle in a rough handling and rough unloading manner, the final static posture of the vehicle is changed into a toppling state.

And after the monitoring device acquires the sensing data, calculating whether the static attitude of the vehicle is in a toppling state. Alternatively, the sensing device may output attitude data, and the monitoring device may determine whether the vehicle has toppled and the degree of toppling based on the attitude data.

The acceleration is measured in advance when the vehicle is normally placed as a standard acceleration vector. If the acceleration of a plurality of continuous sampling periods is equivalent to the gravity acceleration, the monitoring device considers that the vehicle is in a static state. And the monitoring device calculates an included angle between the acceleration vector and the standard acceleration vector during the stationary period of the vehicle, if the included angle is zero or small, the vehicle is in a normal placing state, and if the included angle is larger than a preset angle threshold value, the vehicle is in a dumping state. The preset angle threshold may be 70 degrees or 80 degrees.

And step S308, determining whether the vehicle rolls over during the locking period according to the data.

The vehicle may roll over when someone intentionally damages the vehicle or when the operator treats the vehicle in a rough handling, rough unloading manner.

In one example, the monitoring device calculates the change in the posture of the vehicle after acquiring the sensing data, and when it is determined that the change in the posture of the vehicle is large in a short time, it indicates that the vehicle has rolled over. Or the sensing device can output inclination angle data and posture data, and the monitoring device determines that the vehicle has a relatively large change in posture in a short time according to the inclination angle data and the posture data, so that the vehicle is turned over.

For example, the acceleration of the vehicle is measured in advance when the vehicle is normally placed as a standard acceleration vector. After the vehicle is thrown, the monitoring device calculates an included angle between the acceleration vector read from the sensing module and the standard acceleration vector. The angle is used to determine whether the vehicle is rolling.

When the included angle is zero or small, the vehicle is determined to be placed normally, and when the included angle is larger than a preset angle threshold value, the vehicle is determined to be toppled. The preset angle threshold may be 70 degrees or 80 degrees. Wherein when the vehicle is at about 90 degrees, it is said that the vehicle is horizontally disposed, and when the included angle is at about 180 degrees, it can be determined that the vehicle is inverted. When the included angle corresponding to a certain sampling period is about 180 degrees, the included angle before a short time is about 0 degrees or about 90 degrees, and the included angle after the short time is about 0 degrees or about 90 degrees, the situation that the vehicle is placed from normal or horizontal placement to inversion and then is placed from inversion to normal or horizontal placement is shown, and the vehicle rolls.

In one example, when the monitoring device detects that the acceleration direction changes drastically in a short time, it may be determined that the vehicle is rolling.

In the embodiment of the present disclosure, each preset threshold or preset value may be determined through engineering simulation or engineering test according to an actual application scenario. The preset time length, the preset falling distance and the continuous multiple sampling periods specifically comprise several sampling periods, and can be determined through engineering simulation or engineering test according to the actual application scene.

And step S206, performing alarm processing when the abnormal motion of the vehicle is determined during the locking process.

In one example, the monitoring device sounds a warning tone in the event that it is determined that abnormal movement of the vehicle has occurred during the lock-off period.

In one example, the monitoring device alerts the server in the event that it is determined that abnormal motion of the vehicle has occurred during the lock-off period.

For example, the monitoring device may send an alarm to the server, and may send an alarm message to the server to notify the server of abnormal movement of the vehicle during the locking period, and further, may notify the server of which abnormal movement of the vehicle has occurred.

In one example, the monitoring device alerts the server, which may send alert information to the server and the data to the server, which may further analyze the data to determine whether the vehicle has experienced violent behavior.

In one example, the server may classify or rank the abnormal behavior based on the data. For example, when the falling distance of the free fall behavior of the vehicle is in the range of 1-2 meters, it is determined that rough handling or rough unloading is possible in operation. When the falling distance of the free falling body of the vehicle is more than 2 meters, the possibility of malicious violent vandalism is determined, and immediate field intervention is required.

In one example, the server may combine other data to determine whether the vehicle has encountered or traced the source of the violent behavior. For example, the server incorporates the geographic location data of the vehicle, and deems someone vandalized the vehicle when it is determined that free fall behavior has occurred with the vehicle in a concurrent or subsequent location, such as under a bridge, in a river. For example, the server combines the operation data, finds that abnormal movement always occurs at a vehicle release position for which a certain vehicle release person is responsible, and the release person checks whether the vehicle release person unloads in a rough unloading manner on the spot. For example, the server, in combination with the geographic location information, finds that a plurality of vehicles report warning information of abnormal movement in a short time (for example, within 10 minutes) at the same geographic location, and in combination with the operation information, may infer a possible rough unloading behavior of the operator.

In one example, before step S204, the method may further include step S100.

Step S100, determining whether the vehicle generates a predefined slight vibration during the locking period according to the data, and after determining that the vehicle generates the slight vibration during the locking period, starting step S204, namely, starting to determine whether the vehicle generates abnormal motion during the locking period according to the data output by the sensing module.

In one example, the monitoring device may be a vehicle lock, which has a wake-up mode and a sleep mode in order to conserve power. In the sleep mode, the sensing module works normally, but the main control chip and some peripherals of the lock enter the sleep state.

When the lock is in a locking state and enters a sleep mode from a wake mode, the interrupt threshold of the acceleration sensor is configured to be a first interrupt threshold. When the lock is in a locking state and enters a wake-up mode from a sleep mode, the interrupt threshold value of the acceleration sensor is configured to be a second interrupt threshold value. The second interrupt threshold is greater than the first interrupt threshold. The first interruption threshold here is a threshold corresponding to slight vibrations, and the second interruption threshold is a threshold corresponding to severe vibrations. The second interrupt threshold is, for example, 14G.

That is, when the lock is in the off-lock state and in the sleep mode, if the acceleration value detected by the acceleration sensor is greater than the first interrupt threshold, indicating that the vehicle has slightly vibrated, an interrupt signal needs to be sent to wake up the lock. Therefore, when the vehicle lock is in the lock-off state and in the sleep mode, if the interrupt signal sent by the sensing module is received, the vehicle lock is controlled to enter the wake-up mode and the step S204 is started to be executed, that is, whether the preset abnormal motion of the vehicle occurs during the lock-off period is started to be detected.

When the lock is in a locking state and in an awakening mode, if the acceleration value detected by the acceleration sensor is larger than a second interrupt threshold value, the lock needs to be informed when the vehicle vibrates violently, and the lock can determine that the vehicle vibrates violently when receiving the interrupt signal.

Referring now to fig. 3, a specific example of a method of monitoring a vehicle is illustrated. The vehicle lock comprises an acceleration sensor, a processor and a memory. The method is executed by a processor and comprises steps S501-S505.

Step S501, when the lock is in the locking state and the vehicle enters the sleep mode from the wake mode, the processor configures an interrupt threshold of the acceleration sensor as a first interrupt threshold.

In step S502, when the lock is in the locked state and in the sleep mode, the processor may receive an interrupt signal generated by the acceleration sensor. The processor executes step S503 if it receives the interrupt signal transmitted from the acceleration sensor.

And S503, controlling the vehicle lock to enter the wake-up mode from the sleep mode by the processor, configuring the interrupt threshold of the acceleration sensor as a second interrupt threshold, and starting to execute the step S504. The second interrupt threshold is greater than the first interrupt threshold. The second interrupt threshold is, for example, 14G.

And step S504, when the lock is in the locking state and in the wake-up mode, the processor determines whether the vehicle has preset abnormal motion during the locking period according to the data output by the acceleration sensor.

The preset abnormal motion may be a free-fall motion, a severe vibration, a toppling, a rolling motion, etc. over a preset time period or over a preset falling distance.

In one example, if the processor receives an interrupt signal sent by the acceleration sensor while the lock is in the off state and in the wake mode, it is determined that abnormal motion of the vehicle occurs during the off state.

And step S505, the processor performs alarm processing when determining that the vehicle has abnormal motion during the locking process.

According to the method for monitoring the vehicle, the data output by the sensing module on the vehicle are obtained, whether the preset abnormal motion occurs in the locking period of the vehicle is determined according to the data, and the alarm processing is carried out under the condition that the abnormal motion occurs in the locking period of the vehicle, so that the safety of the vehicle is effectively improved, and the service life of the vehicle is prolonged.
