It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
During parking of the vehicle, the vehicle wakes up the whole vehicle at regular time, a storage battery sensor detects the electric quantity state of the storage battery, and if the battery is detected to be deficient, an automatic power supplementing module of the vehicle sends a power supplementing request to a high-voltage system so as to supplement power; if the vehicle does not have high voltage for a period of time after the power-up request is sent, the power-up failure is considered, the main node controller of the storage battery can record the failure event in the nonvolatile memory, and the vehicle is dormant and does not wake up the whole vehicle after the next time.
Because the low SOC and low voltage active wake-up strategy of the storage battery sensor is closed, the automatic power-up function is completely disabled, and if the automatic power-up response condition of the high-voltage system is restored to a responsive state in the period, the power-up request cannot be sent out, so that the vehicle cannot timely supplement energy when power-up is needed, and the normal operation of the vehicle is affected.

The automatic power supply method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The method comprises the steps that a storage battery sensor 102 regularly detects battery state data of a storage battery, a wake-up signal is generated when the battery state data of the storage battery is smaller than a preset wake-up threshold value, the wake-up signal is transmitted to a main node controller 104 of the storage battery sensor 102, and the main node controller 104 receives the wake-up signal generated by the storage battery sensor 102 and wakes up the whole vehicle according to the wake-up signal; the main node controller 104 sends a power-up request to the high-voltage controller 106 in the whole vehicle and receives a first state signal fed back by the high-voltage controller 106; if the first state signal indicates that the current state does not meet the automatic power-up response condition, the master node controller 104 generates a first configuration signal and sends the first configuration signal to the storage battery sensor 102 to instruct the storage battery sensor 102 to exit the active wake-up strategy and control the whole vehicle to sleep; the master node controller 104 sets a timed wake-up duration, wakes up the whole vehicle after the timed wake-up duration is up, and controls the battery sensor 102 to execute the active wake-up strategy again. The battery sensor 102 may be a current sensor, an Intelligent Battery Sensor (IBS), or the like.
In one embodiment, as shown in fig. 2, an automatic power-up method is provided, and the method is applied to the master node controller in fig. 1 for illustration, and includes the following steps:
step 202, receiving a wake-up signal generated by a storage battery sensor, and waking up the whole vehicle according to the wake-up signal; the wake-up signal is generated when the battery state data of the storage battery is less than a preset wake-up threshold.
The storage battery sensor is used for detecting battery state data of the storage battery at fixed time, generating a wake-up signal when the battery state data is smaller than a preset wake-up threshold value, and transmitting the wake-up signal to the main node controller. In this embodiment, the battery sensor is a slave node, the master node controller is a master node, the slave node (battery sensor) is responsible for collecting and transmitting data, and the master node (master node controller) is responsible for receiving, processing and analyzing data transmitted from the slave node.
Battery state data refers to the current performance and health of the battery. For example, the battery state data specifically includes battery capacity, battery voltage, battery temperature, and the number of cycles of the battery, and the like. The preset wake-up threshold refers to a preset threshold corresponding to the battery state data.
The wake-up signal is a specific electric signal for waking up the whole vehicle. Waking up the whole vehicle refers to starting the engine of the vehicle, activating the electrical system of the vehicle, etc.
Specifically, the battery sensor periodically detects battery state data of the battery according to a preset period, the battery sensor compares the detected battery state data with a preset wake-up threshold, and if the battery state data is smaller than the preset wake-up threshold, a wake-up signal needs to be generated and transmitted to the master node controller. The main node controller is awakened after receiving the awakening signal, and wakes up the whole vehicle. If the battery state data is greater than or equal to the preset wake-up threshold, the battery sensor does not generate a wake-up signal and the battery state data is saved.
Step 204, a power supplementing request is sent to a high-voltage controller in the whole vehicle, and a first state signal fed back by the high-voltage controller is received.
The power supplementing request is used for requesting the high-voltage controller to control the high-voltage system to supplement power for the storage battery.
And the high-voltage controller is used for judging whether the power supply request can be responded according to the electric quantity of the power battery and the fault state of the high-voltage system in real time and converting the condition of whether the automatic power supply response condition is met into a first state signal. The high-voltage system refers to a high-voltage driving part system which is connected with a direct current bus of the power battery or driven by a power battery power supply in the electric automobile. After the whole vehicle wakes up, the high-voltage controller periodically detects whether the current state meets the automatic power-on response condition according to a preset detection period, and feeds back a first state signal to the main node controller.
And the first state signal is used for representing whether the current state meets the automatic power-on response condition. For example, a first state signal of 0 indicates that the current state satisfies the auto-power-up response condition, and a first state signal of 1 indicates that the current state does not satisfy the auto-power-up response condition.
The automatic power-supplementing response condition refers to a condition that the high-voltage system can automatically supplement power under a certain condition. For example, the auto-replenishment response condition may include a low threshold of battery charge, a vehicle parking status, availability of a charging device, and so forth.
Specifically, after the whole vehicle wakes up, the high-voltage controller periodically detects whether the current state meets the automatic power-on response condition according to a preset detection period, and feeds back a first state signal to the main node controller; the main node controller sends a power supplementing request to a high-voltage controller in the whole vehicle and receives a first state signal fed back by the high-voltage controller.
In some embodiments, fig. 3 is a control flow chart of automatic power supply after the whole vehicle is awakened in one embodiment, as shown in fig. 3, after the whole vehicle is awakened, the automatic power supply module of the master node controller again judges the battery state data of the storage battery and a preset awakening threshold value, that is, the automatic power supply module reads the battery state data of the storage battery; if the battery state data of the storage battery is greater than or equal to a preset wake-up threshold value, the automatic power-up module does not generate a power-up request; if the battery state data of the storage battery is smaller than a preset wake-up threshold value, the automatic power-up module sends a power-up request to the high-voltage controller; the high-voltage controller controls the high-voltage system to judge whether the power supplementing request can be responded or not in real time according to the electric quantity of the power battery and the fault state of the high-voltage system. If the power battery is low in electric quantity or a high-voltage system has a fault state that high voltage cannot be applied, determining that an automatic power-supplementing response condition cannot be met, enabling the whole vehicle to be high-voltage, enabling the whole vehicle to meet a dormancy condition, and dormancy; if the high-voltage controller controls the high-voltage system to respond to the power supplementing request according to the electric quantity of the power battery and the fault state of the high-voltage system in real time, the high-voltage system is determined to meet the automatic power supplementing response condition, the high-voltage system carries out a high-voltage power-on flow, and the high-voltage system supplements power for the storage battery.
And 206, if the first state signal indicates that the current state does not meet the automatic power-on response condition, generating a first configuration signal, and sending the first configuration signal to the storage battery sensor to instruct the storage battery sensor to exit the active wake-up strategy and control the whole vehicle to sleep.
The first configuration signal is a signal for indicating the storage battery sensor to exit the active wake-up strategy.
The active wake-up strategy refers to a strategy that a storage battery sensor actively tries to wake up the whole vehicle. In the related art, the whole vehicle wakes up the storage battery sensor, under the condition of the power deficiency of the storage battery, the whole vehicle with larger power consumption is waken up preferentially, and then the storage battery sensor is waken up, so that the power deficiency condition of the storage battery can be further aggravated. The active wake-up strategy of the embodiment is to set a timed wake-up function in the storage battery sensor, detect the battery state data of the storage battery after the storage battery is awakened, and wake up the whole vehicle when the battery state data of the storage battery is smaller than a preset wake-up threshold value, so that the power consumption of the storage battery can be reduced.
The battery sensor exits the active wake-up strategy, meaning that the battery sensor will no longer actively attempt to wake up the entire vehicle. There are various ways in which the battery sensor may exit the active wake-up strategy. For example, the master node controller sends a specific control signal to the battery sensor, which may be a specific electrical signal or command in a communication protocol, for instructing the battery sensor to exit the active wake-up strategy. For example, by software command configuration, in particular if the battery sensor can be configured by software, the battery sensor can be instructed to change its wake-up strategy, including exiting the active wake-up strategy, by sending specific software commands or scripts. For example, the wake-up threshold or parameter is adjusted, in particular, the wake-up strategy thereof is changed by adjusting a preset wake-up threshold of the battery sensor. The battery sensor may be indirectly exited from the active wake-up strategy by setting the preset wake-up threshold to a value that is not applicable to the current state.
In some embodiments, if the first status signal characterizes the current status as meeting the automatic power up response condition, then power up the battery is performed.
Specifically, the master node controller detects the first status signal to determine whether the current status satisfies the auto-power-up response condition. If the current state represented by the first state signal does not meet the automatic power-up response condition, the master node controller generates a first configuration signal and sends the generated first configuration signal to the storage battery sensor. After the storage battery sensor receives the first configuration signal, the active wake-up strategy is exited according to the indication of the first configuration signal, and the storage battery sensor does not actively attempt to wake up the whole vehicle. In addition, the master node controller also controls the whole vehicle to enter a dormant state. And if the current state represented by the first state signal meets the automatic power-up response condition, the main node controller supplements power for the storage battery through the high-voltage controller.
And step 208, setting a timed wake-up time length, waking up the whole vehicle after the timed wake-up time length is up, and controlling the storage battery sensor to execute the active wake-up strategy again.
The time of the timed wake-up time refers to a preset time period, and indicates how long the master node controller wakes up the whole vehicle. The time wake-up duration can be adjusted according to different application scenes and requirements. For example, the timed wake-up period may be 3 days.
The battery sensor re-executes the active wake-up strategy, which means that the battery sensor actively tries to wake up the whole vehicle again according to preset conditions.
Specifically, when the first state signal indicates that the current state does not meet the automatic power-on response condition, the main node controller sets a specific timed wake-up time length, the main node controller starts timing, and after the timed wake-up time length is up, the main node controller generates a timed wake-up enabling signal, and the main node controller wakes up the whole vehicle according to the timed wake-up enabling signal, and the whole vehicle is waken up from the dormant state; after the whole vehicle is awakened, the main node controller sends a control signal to the storage battery sensor to instruct the storage battery sensor to execute the active awakening strategy again.
In the automatic power-up method, when the battery state data of the storage battery is smaller than the preset wake-up threshold value, the whole vehicle is waken up, a first state signal fed back by the high-voltage controller is received, if the first state signal represents that the current state does not meet the automatic power-up response condition, a first configuration signal is generated, and the first configuration signal is sent to the storage battery sensor to instruct the storage battery sensor to exit an active wake-up strategy, and the whole vehicle is controlled to sleep, so that unnecessary energy consumption can be prevented; when the current state does not meet the automatic power-on response condition, the timed wake-up time is set, the whole vehicle is waken after the timed wake-up time is up, the storage battery sensor is controlled to execute the active wake-up strategy again, the whole vehicle can be ensured to check the state again after the specific time by setting the timed wake-up time, and the storage battery sensor can communicate with the whole vehicle again by executing the active wake-up strategy again, so that the whole vehicle is waken again and power-on is carried out, the situation that the power cannot be supplemented again due to power-on failure in the related art is avoided, the timely energy supplement of the vehicle when the power-on is needed is ensured, and the normal operation of the vehicle is ensured.
In one embodiment, sending a first configuration signal to the battery sensor to instruct the battery sensor to exit the active wake-up strategy includes:
and sending a first configuration signal to the storage battery sensor to instruct the storage battery sensor to set a preset wake-up threshold value to an invalid value so as to enable the storage battery sensor to exit the active wake-up strategy.
Wherein, the invalid value refers to a value exceeding a normal working range or a special marking value for indicating that the preset wake-up threshold is not valid currently.
In some embodiments, the first configuration signal includes instructions for instructing the battery sensor to set the preset wake-up threshold to an invalid value.
Specifically, the master node controller sends a first configuration signal to the battery sensor. The battery sensor parses after receiving the first configuration signal to understand the intent of the master node controller. The storage battery sensor sets a current preset wake-up threshold value set in the storage battery sensor to be an invalid value according to the indication of the first configuration signal. After the preset wake-up threshold is set to an invalid value, the battery sensor will not meet the condition of actively waking up the whole vehicle, so the battery sensor exits the active wake-up strategy.
In this embodiment, the preset wake-up threshold is set to an invalid value, and the battery sensor will not actively wake up the whole vehicle under the condition of meeting the invalid value, so that unnecessary wake-up and energy consumption can be reduced, thereby saving energy and prolonging the endurance mileage of the electric vehicle.
In one embodiment, controlling the battery sensor to re-execute the active wake-up strategy includes:
and receiving a second state signal fed back by the high-voltage controller in the whole vehicle, generating a second configuration signal if the second state signal represents that the current state meets the automatic power-on response condition, and sending the second configuration signal to the storage battery sensor to instruct the storage battery sensor to execute the active wake-up strategy again.
The second state signal refers to a signal which is fed back by the high-voltage controller and used for representing whether the current state meets the automatic power-on response condition after the whole vehicle wakes up again. The first state signal and the second state signal are signals representing whether the current state meets the automatic power-on response condition or not, the difference is that the generation time of the first state signal and the second state signal is different, the first state signal is a signal fed back under the scene that the whole vehicle is awakened for the first time or the last time is awakened successfully, and the second state signal is a signal generated when the whole vehicle is awakened again after the power-on failure.
A second configuration signal refers to a signal for instructing the battery sensor to re-execute the active wake-up strategy.
Specifically, under the condition that the power supply fails after the whole vehicle is awakened last time, after the time of the regular awakening time is up, the main node controller generates a regular awakening enabling signal, and the main node controller awakens the whole vehicle according to the regular awakening enabling signal, so that the whole vehicle is awakened from a dormant state; after the whole vehicle is awakened, the main node controller receives a second state signal from the high-voltage controller and analyzes the second state signal to judge whether the current state meets the automatic power-on response condition. If the current state meets the automatic power-up response condition, the master node controller generates a second configuration signal and sends the second configuration signal to the storage battery sensor. After receiving the second configuration signal, the storage battery sensor analyzes the content of the second configuration signal and re-executes the active wake-up strategy accordingly.
In this embodiment, after the whole vehicle wakes up again, by receiving the second state signal and determining whether the current state meets the automatic power-up condition, and when the current state meets the automatic power-up response condition, generating the second configuration signal and sending the second configuration signal to the battery sensor to instruct the battery sensor to execute the active wake-up strategy again, the whole vehicle can be actively awakened to perform power-up at a proper time, thereby avoiding the situation that the power-up failure in the related art causes that the power-up cannot be performed again, ensuring that the vehicle supplements energy in time when the power-up is needed, and ensuring the normal operation of the vehicle.
In one embodiment, sending a second configuration signal to the battery sensor to instruct the battery sensor to re-execute the active wake-up strategy includes:
and sending a second configuration signal to the storage battery sensor to instruct the storage battery sensor to reset the preset wake-up threshold so that the storage battery sensor re-executes the active wake-up strategy.
As can be seen from the above embodiments, in the case of a power failure after the last wake-up of the whole vehicle, the battery sensor sets the preset wake-up threshold to an invalid value, so that the battery sensor exits the active wake-up strategy, and therefore, when the whole vehicle is restarted, in order to ensure that the active wake-up strategy can be executed again, the preset wake-up threshold needs to be reset, so that the preset wake-up threshold is converted from the invalid value to the valid value.
In some embodiments, the second configuration signal includes instructions for instructing the battery sensor to set the preset wake-up threshold to a valid value.
The purpose of resetting the preset wake-up threshold is to change it from a previously inactive value to an active value so that the battery sensor can re-execute the active wake-up strategy in accordance with this new threshold.
Specifically, when the whole vehicle wakes up again and the second state signal fed back by the high-voltage controller represents that the current state meets the automatic power-on response condition, the main node controller sends a second configuration signal to the storage battery sensor, the storage battery sensor wakes up after receiving the second configuration signal, and sets a preset wake-up threshold as an effective value according to the second configuration signal, after the preset wake-up threshold is set as the effective value, the storage battery sensor executes an active wake-up strategy again, namely the storage battery sensor detects the battery state data of the storage battery again, compares the battery state data with the reset effective value, and judges whether to generate the wake-up signal according to a comparison result.
In this embodiment, only when the second state signal fed back by the high-voltage controller indicates that the current state meets the automatic power-up response condition, the second configuration signal is sent to the storage battery sensor, and the on-demand wake-up strategy avoids unnecessary wake-up and energy consumption.
In one embodiment, the automatic power up method further comprises:
and if the second state signal indicates that the current state does not meet the automatic power-on response condition, executing the step of setting the time-on duration, and continuing to execute until the storage battery sensor executes the active-on strategy again.
The second state signal indicates that the current state does not meet the automatic power-on response condition, and indicates that the automatic power-on request cannot be responded after the whole vehicle is awakened at the moment, the automatic power-on still fails, and the next time of timed awakening duration is reset for avoiding energy consumption without requesting the high-voltage controller to power on again.
In some embodiments, in the process of resetting the next time of the timed-wakeup duration, if the new timed-wakeup duration is not received, the originally set timed-wakeup duration is used as the reset timed-wakeup duration.
Specifically, when the whole vehicle wakes up again and the second state signal fed back by the high-voltage controller indicates that the current state does not meet the automatic power-on response condition, the main node controller returns to the step of setting the time-on duration, and continues to execute until the storage battery sensor executes the active wake-up strategy again.
In some embodiments, fig. 4 is a control flow chart of active wake-up of a battery sensor in one embodiment, as shown in fig. 4, an automatic power-up module of a master node controller receives a first state signal A1 fed back by a high voltage controller, the automatic power-up module determines whether the value of the first state signal A1 is 0, if the value of the first state signal A1 is 0, the current state is characterized as meeting an automatic power-up response condition, a high voltage system performs a high voltage power-up process, and the high voltage system supplements power to the battery. If the value of the first state signal A1 is 1, the current state is characterized as not meeting the automatic power-up response condition, the automatic power-up module generates a first configuration and sends the first configuration to the storage battery sensor to instruct the storage battery sensor to set the preset wake-up threshold to an invalid value, so that the storage battery sensor exits the active wake-up strategy. Meanwhile, the automatic power-up module sets a timed wake-up time length, the whole vehicle enters dormancy, and the whole vehicle is awakened after the timed wake-up time length is up. After the whole vehicle is awakened again, the automatic power-on module receives a second state signal A2 fed back by the high-voltage controller in the whole vehicle, if the second state signal A2 is 0, and the current state is represented to meet the automatic power-on response condition, the automatic power-on module generates a second configuration signal and sends the second configuration signal to the storage battery sensor to instruct the storage battery sensor to reset a preset awakening threshold value, after the preset awakening threshold value is set to an effective value, the storage battery sensor re-executes an active awakening strategy, namely the storage battery sensor re-detects the battery state data of the storage battery, compares the battery state data with the reset effective value, and judges whether to generate the awakening signal according to a comparison result. If the second state signal A2 is 1 and the current state does not meet the automatic power-on response condition, the automatic power-on module returns to the step of setting the time wake-up duration and continues to execute until the storage battery sensor executes the active wake-up strategy again.
In this embodiment, when the whole vehicle wakes up again and the second state signal fed back by the high-voltage controller indicates that the current state does not meet the automatic power-on response condition, the step of setting the time-on duration is returned, and the execution is continued until the storage battery sensor executes the active wake-up strategy again, so that unnecessary frequent wake-up and energy consumption can be avoided.
In one embodiment, the preset wake-up threshold comprises a preset voltage wake-up threshold and a preset state of charge threshold, and the active wake-up strategy comprises:
1. the storage battery sensor detects battery state data of the storage battery according to a preset period; the battery state data includes state of charge, real-time voltage, and detection accuracy data.
The detection precision data represents a quantization index of the detection precision of the storage battery sensor. For example, voltage detection accuracy, current detection accuracy, state of charge detection accuracy, temperature detection accuracy, and the like. In this embodiment, the detection accuracy data characterizes the state of charge detection accuracy of the battery sensor.
Specifically, the battery sensor starts a detection routine at a preset time point to start detecting battery state data of the battery.
2. If the detection precision data in the battery state data is smaller than the preset precision data, determining first awakening information according to the real-time voltage and a preset voltage awakening threshold value; the first wake-up information characterizes whether the real-time voltage is smaller than a preset voltage wake-up threshold.
The detection accuracy data in the battery state data is smaller than the preset accuracy data, the current detected state of charge is characterized by lower accuracy, more reliable reference cannot be provided, and erroneous judgment may be caused if the state of the storage battery is judged by depending on the current detection data. Therefore, in order to improve the accuracy of the battery sensor in judging whether the whole vehicle needs to be awakened, in this embodiment, when the detection accuracy data in the battery state data is smaller than the preset accuracy data, the real-time voltage is adopted to replace the state of charge to judge, and the first awakening information is determined to be more stable according to the real-time voltage and the preset voltage awakening threshold value, because the real-time voltage is a relatively direct and real-time parameter, the working state of the battery can be reflected more rapidly.
Specifically, the storage battery sensor acquires detection precision data, if the detection precision data is smaller than preset precision data, the real-time voltage is adopted to replace the state of charge to judge, the real-time voltage is compared with a preset voltage awakening threshold value, and first awakening information is obtained according to a comparison result.
3. If the detection precision data in the battery state data is greater than or equal to the preset precision data, determining second wake-up information according to the state of charge and a preset state of charge threshold value; the second wake-up information characterizes whether the state of charge is less than a preset state of charge threshold.
The detection precision data in the battery state data are larger than or equal to the preset precision data, the fact that the currently detected state of charge precision is higher can provide more reliable references, and at the moment, the second wake-up information is determined to have more reference value according to the state of charge and the preset state of charge threshold value. Therefore, when the detection precision data in the battery state data is greater than or equal to the preset precision data, the state of charge is adopted for judging, and the state of charge is a comprehensive parameter which reflects the overall working condition of the storage battery and is not only the real-time voltage condition. Therefore, this way of discrimination is more comprehensive.
Specifically, the storage battery sensor acquires detection precision data, if the detection precision data is greater than or equal to preset precision data, the state of charge is adopted to judge, the state of charge is compared with a preset state of charge threshold value, and second wake-up information is obtained according to a comparison result.
4. If the first wake-up information indicates that the real-time voltage is smaller than a preset voltage wake-up threshold value and/or the second wake-up information indicates that the state of charge is smaller than a preset state of charge threshold value, the storage battery sensor generates a wake-up signal.
In some embodiments, the battery sensor stores the battery state data if the first wake-up information characterizes the real-time voltage to be greater than or equal to a preset voltage wake-up threshold, or the second wake-up information characterizes the state of charge to be greater than or equal to a preset state of charge threshold.
The first wake-up information represents that the real-time voltage is larger than or equal to a preset voltage wake-up threshold value, or the second wake-up information represents that the state of charge is larger than or equal to a preset state of charge threshold value, and represents that the storage battery is not in a power shortage state.
Specifically, if the first wake-up information indicates that the real-time voltage is smaller than a preset voltage wake-up threshold value and/or the second wake-up information indicates that the state of charge is smaller than a preset state of charge threshold value, the storage battery sensor determines that the storage battery is in a power shortage state currently, and generates a wake-up signal to wake up the whole vehicle to supplement power. If the first wake-up information represents that the real-time voltage is greater than or equal to a preset voltage wake-up threshold value or the second wake-up information represents that the state of charge is greater than or equal to a preset state of charge threshold value, the storage battery is determined not to be in a power-shortage state, and the storage battery sensor stores the battery state data and does not generate a wake-up signal.
In some embodiments, fig. 5 is a control flow chart of an active wake-up strategy in one embodiment, as shown in fig. 5, after the whole vehicle is dormant, a battery sensor monitors the state of charge SOC and real-time voltage uBatt of the battery, the time is counted for n minutes from the time of dormancy of the battery sensor, after the time is counted, detection precision data soctate is obtained, if soctate is equal to 1 or 2, the monitoring precision of the state of charge SOC is relatively accurate, and the state of charge SOC is compared with a preset state of charge threshold value SOC low The magnitude relation between the charge state and the charge state is greater than or equal to a preset charge state threshold value SOC low The battery sensor wakes up the master node controller; if the state of charge SOC is greater than or equal to the preset state of charge threshold SOC low The battery sensor does not wake up the master node and the vehicle continues to sleep.
If SOCSTATE is equal to 0, the monitoring accuracy of the state of charge SOC is inaccurate, and the real-time voltage uBatt is compared with a preset voltage wake-up threshold uBatt low The magnitude relation between the two; if the real-time voltage uBatt is smaller than the preset voltage wake-up threshold uBatt low Storage battery sensorThe master node controller is awakened; if the real-time voltage uBatt is greater than or equal to the preset voltage wake-up threshold uBatt low The battery sensor does not wake up the master node and the vehicle continues to sleep.
In this embodiment, different discriminating modes are adopted according to different detection precision data, so that not only can the accuracy of discrimination be ensured, but also the pertinence of discrimination can be improved.
