Detailed implementation manners

[0017] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. Various details of the embodiments of the present application are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following.

[0018] As mentioned in the background art, the prior art has problems such as high algorithm difficulty and high development cost in automatic windshield wiper control. In response to this, the present application obtains the mapping relationship between the trigger parameters and the vehicle control strategy, and when it is detected that the vibration of the body sheet metal meets the preset conditions, according to the measured trigger parameters and the mapping relationship, executes the vehicle control strategy corresponding to the measured trigger parameters, with simple method, low cost and strong reliability.

[0019] The applicant has found that when water drops fall on the vehicle body, the body sheet metal will vibrate; at this time, if an IMU (Inertial Measurement Unit) is fixed to the corresponding position of the vehicle body, the IMU can collect the vibration data of the vehicle body. Usually, the IMU has three axes X, Y, and Z, and a single-axis IMU can also be selected. Finally, it is installed on the vehicle, and only one axis that is convenient for calibration and distinction can be used to implement the data. The water drops in this embodiment can be raindrops falling during rainy days or water drops splashing on the vehicle body from surrounding water sources.

[0020] Taking raindrops as an example below, the principle of detecting rainfall with a single axis is introduced.

[0021] 1. When a single raindrop falls on the vehicle body, the acceleration-time relationship detected by the IMU is as Figure 1As shown in the figure. (1) At time T1, the event of raindrops falling on the vehicle body occurred. At this time, at time T2, the acceleration data rose above the raindrop impact threshold and did not exceed the raindrop impact invalid threshold; at time T3, the IMU collected this data. (2) As the raindrop falling event ended, the acceleration value gradually converged to the data at rest. At time T4, the acceleration acquisition value began to be lower than the raindrop impact threshold and finally decreased to the static state.

[0022] 2. When two consecutive raindrops fall on the vehicle body, the acceleration-time relationship detected by the IMU is as Figure 2 shown. Among them, from T1 to T2 is the time of the first raindrop falling event. In this time window, the acceleration value will exceed the raindrop impact threshold and gradually converge to the static state; T3 - T4 is the delay window of the second raindrop falling event. In this time window, the acceleration value will exceed the raindrop impact threshold and gradually converge to the static state.

[0023] 3. When two raindrops with irregular time intervals fall on the vehicle body, the acceleration-time relationship detected by the IMU is as Figure 3 shown. Among them, the acceleration directions of the vehicle body vibrations caused by the two raindrops are opposite. (1) At time T1, the first raindrop falling on the vehicle body event occurred. At this time, at time T2, the acceleration data rose above the raindrop impact threshold and did not exceed the raindrop impact invalid threshold; at time T3, the IMU collected data above the raindrop impact threshold again and did not exceed the raindrop impact invalid threshold. At time T4, the second raindrop fell on the vehicle body. (2) As the raindrop falling event ended, the acceleration value gradually converged to the data at rest. At time T7, the acceleration acquisition value began to be lower than the raindrop impact threshold and finally decreased to the static state.

[0024] 4. When two raindrops with irregular time intervals fall on the vehicle body, the acceleration-time relationship detected by the IMU is as Figure 4 shown. Among them, the acceleration directions of the vehicle body vibrations caused by the two raindrops are the same. (1) At time T1, the first raindrop falling on the vehicle body event occurred. At this time, at time T2, the acceleration data rose above the raindrop impact threshold and did not exceed the raindrop impact invalid threshold; at time T3, the IMU collected data above the raindrop impact threshold again and did not exceed the raindrop impact invalid threshold. At time T4, the second raindrop fell on the vehicle body. (2) As the raindrop falling event ended, the acceleration value gradually converged to the data at rest. At time T6, the acceleration acquisition value began to be lower than the raindrop impact threshold and finally decreased to the static state.

[0025] 5. When multiple raindrops with irregular intervals fall on the vehicle body, the acceleration-time relationship detected by the IMU is as Figure 5As shown in the figure. (1) At time T1, the event of raindrops falling on the vehicle body occurred. At this time, at time T2, the acceleration data rose above the raindrop impact threshold and did not exceed the raindrop impact invalid threshold; at times T3, T6, T7, T8, T9, T10, and T11 respectively, the IMU collected data above the raindrop impact threshold and did not exceed the raindrop impact invalid threshold. (2) As the raindrop falling event ended, the acceleration value gradually converged to the data at rest. At time T12, the acceleration acquisition value began to be lower than the raindrop impact threshold and finally decreased to the stationary state.

[0026] Embodiment 1 Figure 6 It is a flowchart of a vehicle control method provided in this embodiment. This embodiment is applicable to the scenario of vehicle control when water droplets fall on the vehicle body during vehicle startup or vehicle driving. This method can be executed by a vehicle control device, which can be composed of software and / or hardware and is generally integrated in an electronic device. The electronic device can be a vehicle head unit or an ECU. For the convenience of understanding, each step in the control method of this embodiment takes the ECU as the execution entity.

[0027] As Figure 6 shown, this embodiment provides a vehicle control method, including the following steps: S110. Obtain the mapping relationship between the trigger parameters and the vehicle control strategy; the trigger parameters include the water droplet impact window, the number of impacts within the water droplet impact window, the calibrated number of impacts within the water droplet impact window, and the number of water droplet impacts during the current detection period.

[0028] Among them, the water droplet impact window is the vibration period of the vehicle body sheet metal when water droplets fall onto the vehicle body. The number of impacts within the water droplet impact window is the number of times that the acceleration or amplitude of the vehicle body sheet metal exceeds the water droplet impact threshold but does not exceed the water droplet impact invalid threshold within a single vibration period of the vehicle body sheet metal. The calibrated number of impacts within the water droplet impact window is the number of times that the acceleration or amplitude of the vehicle body sheet metal exceeds the water droplet impact threshold but does not exceed the water droplet impact invalid threshold within a calibrated single vibration period of the vehicle body sheet metal. The number of water droplet impacts during the current detection period is the number of times that the acceleration or amplitude of the vehicle body sheet metal exceeds the water droplet impact threshold but does not exceed the water droplet impact invalid threshold during the period from the start of collecting each trigger parameter to the execution of the vehicle control strategy in this round.

[0029] Optionally, the acceleration or amplitude of the vehicle body sheet metal can be collected by an IMU.

[0030] In an optional implementation manner, the mapping relationship includes: When the water droplet impact window exceeds the calibrated water droplet impact window and does not exceed the calibrated water droplet impact window by a preset multiple, the number of impacts within the water droplet impact window does not exceed a first value, and the number of water droplet impacts within the current detection period exceeds a preset number, determine the control strategy to control the wiper to move once; where the preset multiple is greater than 1. When the water droplet impact window exceeds the calibrated water droplet impact window and does not exceed the calibrated water droplet impact window by a preset multiple, and the number of impacts within the water droplet impact window is greater than the first value and does not exceed a second value, determine the control strategy to control the wiper to move intermittently. When the number of impacts within the calibrated water droplet impact window is greater than the second value and does not exceed a third value, determine the control strategy to control the wiper to move at a low speed. When the number of impacts within the calibrated water droplet impact window is greater than the third value, determine the control strategy to control the wiper to move at a high speed. When the number of water droplet impacts within the current detection period exceeds a fourth value or the number of impacts within the water droplet impact window exceeds a fifth value, determine the control strategy to control the closing of the vehicle windows and sunroof.

[0031] The above preset multiple, first value, second value, third value, fourth value, and fifth value can be obtained by calibration. The calibration method is, for example, to test the vehicle with different amounts of water and collect the numerical ranges of each trigger parameter under different amounts of water, so as to obtain the above values. Optionally, the preset multiple is, for example, 2, the first value is, for example, 1, the preset number is, for example, 10, the second value is, for example, 2, the third value is, for example, 3, the fourth value is, for example, 10, and the fifth value is, for example, 1.

[0032] Among them, intermittent movement, low-speed movement, and high-speed movement are the movement modes of the vehicle's built-in wiper. This embodiment does not make special limitations on this. For example, the intermittent movement is to move once every 5s, the low-speed movement is to move once every 3s, and the high-speed movement is to move once every 1s.

[0033] In an alternative embodiment, the calibrated water droplet impact window is obtained in the following manner: Obtain the vibration periods of the vehicle body sheet metal after multiple single water droplets fall on the vehicle body sheet metal. Determine the calibrated water droplet impact window according to multiple groups of the vibration periods.

[0034] Optionally, when determining the calibrated water droplet impact window according to multiple groups of the vibration periods, the mean value of multiple groups of vibration periods can be used as the calibrated water droplet impact window.

[0035] S120. When it is detected that the vibration of the vehicle body sheet metal meets the preset conditions, execute the vehicle control strategy corresponding to the measured trigger parameter according to the measured trigger parameter and the mapping relationship.

[0036] When it is detected that the vibration of the vehicle body sheet metal satisfies the preset conditions, the measured trigger parameters are corresponded to the mapping relationship, and then the corresponding vehicle control strategy can be obtained, and then the control strategy can be controlled and executed.

[0037] In an alternative embodiment, the preset condition is that the vibration acceleration of the vehicle body sheet metal exceeds the water droplet impact threshold and does not exceed the water droplet impact invalid threshold; The number of impacts is the number of times that the vibration acceleration of the vehicle body sheet metal exceeds the water droplet impact threshold and does not exceed the water droplet impact invalid threshold.

[0038] In this embodiment, the preset conditions and the number of impacts are associated with the vibration acceleration of the vehicle body sheet metal. The acquisition and calculation of the vibration acceleration are simpler than the amplitude, further reducing the complexity of the method.

[0039] In an alternative embodiment, the water droplet impact threshold is obtained in the following manner: Obtain the minimum acceleration of the vehicle body sheet metal after the water droplet drops onto the vehicle body sheet metal under different water volumes; determine the water droplet impact threshold according to the minimum acceleration; The water droplet impact invalid threshold is obtained in the following manner: Obtain the maximum acceleration of the vehicle body sheet metal after the water droplet drops onto the vehicle body sheet metal under different water volumes; determine the water droplet impact invalid threshold according to the maximum acceleration.

[0040] In this embodiment, by obtaining the acceleration of the vehicle body sheet metal after the water droplet drops onto the vehicle body sheet metal under different water volumes, the water droplet impact threshold and the water droplet impact invalid threshold are determined, and the two obtained thresholds are more reliable.

[0041] In an alternative embodiment, the vehicle body sheet metal includes a vehicle engine hood or a vehicle rear tailgate. The vehicle engine hood and the vehicle rear tailgate are relatively flat and have a small thickness, and the vibration detection at these two positions is more obvious.

[0042] In an alternative embodiment, after executing the vehicle control strategy corresponding to the measured trigger parameters, it further includes: Circularly execute that when it is detected that the vibration of the vehicle body sheet metal satisfies the preset conditions, according to the measured trigger parameters and the mapping relationship, execute the vehicle control strategy corresponding to the measured trigger parameters.

[0043] In this embodiment, after each execution of the vehicle control strategy corresponding to the measured trigger parameters, the steps of S120 are circularly executed again, which can ensure that the vehicle control strategy coincides with the real-time water volume change and the control is more intelligent.

[0044] Optionally, before executing the vehicle control strategy corresponding to the measured trigger parameter, it is also necessary to ensure that the ECU is working properly and has no faults.

[0045] The above vehicle control method includes: obtaining the mapping relationship between the trigger parameter and the vehicle control strategy; the trigger parameter includes the water droplet impact window, the number of impacts within the water droplet impact window, the number of impacts within the calibrated water droplet impact window, and the number of water droplet impacts within the current detection period; when it is detected that the vibration of the vehicle body sheet metal meets the preset conditions, according to the measured trigger parameter and the mapping relationship, execute the vehicle control strategy corresponding to the measured trigger parameter. After obtaining a specific mapping relationship, this method can execute the vehicle control strategy corresponding to the measured trigger parameter when it is detected that the vibration of the vehicle body sheet metal meets the preset conditions. The method is simple and has low cost; and this method is overall carried out based on the vibration situation of the vehicle body sheet metal, and the acquisition of the vibration situation of the vehicle body sheet metal is not affected by light under different conditions, which is relatively more reliable. Therefore, the reliability of the control strategy can be improved.
