DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.
[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0022] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings. This application embodiment provides a vehicle collision control method, please refer to Figure 2 , which shows a schematic diagram of an implementation environment of the method provided in an embodiment of the present application. The implementation environment may include: a collision processing unit (ACU) and multiple collision association modules.
[0023] The collision processing unit is connected to each collision-related module through a CAN line and a hard line.
[0024] When the collision processing unit determines that the vehicle has collided, it identifies the collision direction of the vehicle and generates a collision CAN output signal and a collision hard-line output signal based on the collision direction; the collision CAN output signal and the collision hard-line output signal are sent to each collision-related module via the CAN line and the hard line respectively.
[0025] The plurality of collision association modules include collision association module A, collision association module B, collision association module C, . . . and so on.
[0026] The collision association module includes an association module related to the collision direction and an association module not related to the collision direction; Among them, the associated modules that are not related to the collision direction include the door unlocking module, the double flash module, the remote call module, the braking module, etc.; this type of associated module directly controls the corresponding execution unit when the vehicle collides, such as directly controlling the door unlocking, turning on the vehicle double flash, direct remote call, direct vehicle braking, etc. after the collision occurs.
[0027] The associated modules related to the collision direction include steering modules, etc.; after a vehicle collision occurs, this associated module must first determine the direction of the vehicle's collision, and control the vehicle's corresponding execution units according to the collision direction to prevent the vehicle from having a secondary accident. For example, after determining that the vehicle has a side collision, the vehicle's direction must be corrected first, and the vehicle's posture must be adjusted to prevent skidding or rollover.
[0028] like Figure 3 As shown, the collision processing unit (ACU) is also connected to the collision sensors arranged around the vehicle body through hard-wired communication; and receives collision signals obtained by the collision sensors arranged around the vehicle body.
[0029] A collision sensor is also installed inside the collision processing unit (ACU), which also collects the vehicle's collision signal. The collision processing unit determines whether the vehicle has collided based on the collision signal collected by itself and the collision signal obtained by the collision sensors installed around the vehicle body. When it is determined that the vehicle has collided, the collision direction is determined based on the collision signal, and then a collision output signal is generated.
[0030] The present application embodiment provides a vehicle collision control method for application scenarios such as: After a vehicle collision, a fixed collision waveform is generated and output as a collision signal in a single format. This single-shot output fails to guarantee signal accuracy, leading to inaccurate and timely collision control. The current collision waveform only indicates a collision has occurred, but cannot be used to identify the collision direction and adaptively control the vehicle, resulting in inaccurate collision control.
[0031] In order to achieve timely and accurate control of the vehicle after a collision, the embodiment of the present application provides a vehicle collision control method, the flow chart of which is as follows: Figure 1 As shown, taking the method applied to the above implementation environment as an example, the method includes steps 101 to 105.
[0032] In step 101 , a collision signal of a vehicle is acquired.
[0033] In one possible implementation, the acquired vehicle collision signals include external collision signals from collision sensors installed around the vehicle body and collision signals from the vehicle collision processing unit. The external collision signals are acquired by collision sensors installed within the collision processing unit. By comprehensively analyzing these two collision signals, a collision determination is determined, ensuring accurate collision assessment and preventing the possibility of miscontrol of the entire vehicle due to a hit to a specific part of the vehicle.
[0034] In step 102 , it is determined whether the vehicle has collided and the direction of the collision based on the collision signal of the vehicle.
[0035] In one possible implementation, a collision signal outside the vehicle and a collision signal from a vehicle collision processing unit are obtained; Superimposing the two collision signals to obtain a superimposed collision signal; Determine whether the vehicle has collided based on the strength of the superimposed collision signal; When a vehicle collides, the collision direction of the vehicle is determined based on the superimposed collision signals.
[0036] For example, if the intensity of the superimposed collision signal exceeds a set intensity threshold, the vehicle is determined to have collided. If the intensity of the superimposed collision signal is less than or equal to the set intensity threshold, the vehicle is determined not to have collided and is in normal driving. This redundant design ensures the accuracy of vehicle collision judgment and improves vehicle safety.
[0037] In step 103 , when it is determined that the vehicle has collided, the number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms are determined according to the collision direction of the vehicle.
[0038] In one possible implementation, the collision signal processing unit stores collision output signal generation principles corresponding to each collision direction. Each output signal generation principle includes the number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms. When determining a vehicle collision, the collision output signal generation principle is determined based on the collision direction of the vehicle. The number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms are determined based on the determined collision output signal generation principle.
[0039] Since the collision output signal generated by the embodiment of the present application includes a collision CAN output signal and a collision hard-line output signal, it is necessary to determine the number of collision waveforms of the collision CAN output signal and the collision hard-line output signal, the duration of each collision waveform, and the interval time between adjacent collision waveforms respectively.
[0040] Exemplarily, the collision CAN output signal represents the collision waveform through a dominant level; The collision waveform in the collision hard-line output signal includes a low level of a set duration and a high level of a set duration.
[0041] Exemplarily, the durations of the collision CAN output signal and the collision hard-line output signal are both set values; and the interval between the set number of collision waveforms in the front section of the output signal is shorter than the interval between the collision waveforms in the back section.
[0042] The length of the collision CAN output signal generated each time is the same, and the length of the collision hard-line output signal is also the same; the lengths of the collision CAN output signal and the collision hard-line output signal are set according to actual needs, such as the length of the collision CAN output signal is 6s.
[0043] The collision CAN output signal contains multiple dominant levels, except for the display level, the rest are recessive levels.
[0044] By limiting the interval time between the collision waveforms of the first set number of output signals to be shorter than the interval time between the collision waveforms of the second set, high-frequency and rapid output of collision waveforms is achieved, the output efficiency of collision waveforms is improved, and the timeliness of vehicle collision control is ensured. Figure 4 As shown, the front end of determining the collision CAN output signal needs to send out 6 collision waveforms within 500ms, and the period of the 6 collision waveforms is 20ms. The back end only needs to send out one collision waveform in 500ms.
[0045] By continuously sending multiple collision waveforms, it is possible to distinguish the collision direction through the period of the collision waveform, and it is also possible to ensure that the collision association module can receive the collision signal in a timely and accurate manner by sending multiple collision waveforms, thereby achieving timely and effective control of vehicle collisions.
[0046] The collision hard-line output signal can distinguish the collision direction by the duration of the low level and the duration of the high level in the collision waveform.
[0047] For example, a 200ms low-level waveform is converted to a 40mm high-level waveform as the collision waveform of a forward collision; The 220ms low-level waveform is converted to a 20mm high-level waveform as the collision waveform of a rear-end collision, etc.
[0048] In addition, the multiple collision waveforms in the collision hard-line output signal are continuous waveforms. By continuously sending the collision waveforms, it is ensured that the collision association module can receive the collision signal in a timely and accurate manner.
[0049] For example, after determining that the vehicle has collided, the airbag is controlled to ignite and explode.
[0050] In response to current electric vehicle battery safety issues, the present application embodiment adds a faster ignition method. Figure 2 As shown, a collision power-off switch is provided inside the battery pack, which is directly connected to the ACU through a hard wire. When the ACU detonates the airbag, it triggers a high current to melt the collision power-off switch inside the battery pack, instantly cutting off the high voltage power.
[0051] During each ignition cycle, collision events in different directions can trigger the collision output.
[0052] In step 104, a collision output signal is generated according to the number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms; and the collision output signal is sent to a collision association module; In one possible implementation, the number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms are determined according to the collision output signal generation principle to generate a collision output signal, which includes a collision CAN output signal and a collision hard-line output signal (PWM waveform).
[0053] like Figure 4 The generated collision CAN output signal length is 6s. In the initial stage of the 6s signal, 6 collision waveforms with a period of 20ms are sent quickly. These 6 fast collision waveforms are contained in a 500ms period signal. Then the collision waveform is sent according to the 500ms period for 6s.
[0054] Exemplarily, after the collision output signal is sent, the normal waveform signal is sent multiple times at a set high frequency, and then the normal waveform signal is sent at a set low frequency.
[0055] When no collision occurs, the CAN output signal type is "no crash". When a collision occurs, the collision CAN output signal is output immediately. After the collision CAN output signal is sent, the CAN output signal type is adjusted to "no crash". The "no crash" signal with a period of 20ms is sent six times quickly, and then returns to the "no crash" signal with a period of 500ms.
[0056] For example, when no collision occurs, the hard-wired output signal is a normal waveform, the cycle length of the normal waveform is 240ms, and 5 / 6 of each cycle waveform is a high level and 1 / 6 is a low level.
[0057] When it is determined that the vehicle has collided, no matter which stage of the normal waveform it is in, the output waveform is immediately modified to a collision waveform, and multiple collision waveforms are output continuously. The collision waveform is described as a 200ms low level and 40ms high level as an example.
[0058] like Figure 5As shown in the figure, when a collision occurs, the PWM wave is at the end of the high level stage, and the waveform immediately flips to a low level of 200ms and a high level of 40ms.
[0059] like Figure 6 As shown in the figure, when a collision occurs, the PWM wave is in the middle stage of high level, and the waveform immediately flips to a low level of 200ms and a high level of 40ms.
[0060] like Figure 7 As shown in the figure, when a collision occurs, the PWM wave is in the low-level end stage, continues to send a low-level waveform for 200ms, and then turns to a high level for 40mm.
[0061] like Figure 8 As shown in the figure, when a collision occurs, the PWM wave is in the low-level middle stage, continues to send the low-level waveform for 200ms, and then turns to the high level for 40mm.
[0062] exist Figure 5-Figure 8 In the example, 20 cycles of collision waveform are output continuously.
[0063] In step 105 , the collision association module issues corresponding control instructions according to the collision output signal.
[0064] In a possible implementation, the collision association module includes an association module that is not related to the collision direction and an association module that is related to the collision direction; The associated module, which is not related to the collision direction, issues corresponding control instructions based on the earliest collision waveform received; The associated module related to the collision direction issues a corresponding control instruction according to the earliest collision output signal received.
[0065] Exemplarily, the collision association module determines the collision direction according to the duration and interval of the collision waveform in the received collision output signal, and then controls the vehicle according to the collision direction.
[0066] Regardless of whether the collision waveform in the collision CAN output signal or the collision waveform in the collision hard-line output signal is received first, as long as the collision waveform is received, it indicates that the vehicle has collided. The associated module that is not related to the collision direction immediately controls the vehicle according to the waveform to ensure the timeliness of vehicle control.
[0067] Whether it is the collision CAN output signal or the collision hard-line output signal received first, it indicates that the vehicle has collided, and the collision direction of the vehicle can be determined through any output signal. By analyzing the earliest collision output signal received, the collision direction is determined, and then the vehicle is controlled accordingly, further ensuring the timely and accurate control of the vehicle and ensuring vehicle safety.
[0068] A vehicle collision control method provided in an embodiment of the present application further identifies the collision direction of the vehicle after determining that a vehicle collision has occurred, and generates a collision output signal of a corresponding waveform according to the collision direction of the vehicle for output, and a collision association module issues a corresponding control instruction according to the collision output signal; first, the collision output signal contains multiple collision waveforms, and by sending the collision waveforms multiple times, it is ensured that the collision waveforms can be accurately received by the collision association model, thereby performing timely and accurate control of the vehicle; in addition, different collision directions are characterized by the different durations of each collision waveform and the intervals between adjacent collision waveforms. The collision association module can obtain the collision direction according to the collision output signal, thereby performing accurate collision control according to the collision direction, thereby ensuring timely and accurate vehicle control.
[0069] A vehicle collision control method provided in an embodiment of the present application further adds a redundant judgment on whether the vehicle has collided using a collision signal outside the vehicle and a collision signal from a vehicle collision processing unit, thereby improving the accuracy of vehicle collision judgment.
[0070] The vehicle collision control method provided in the embodiments of the present application also ensures the collision signal output rate by sending CAN signals and hard-wire signals. When the CAN signal is affected and the collision association module cannot receive the CAN signal, it can promptly determine that a vehicle collision has occurred by receiving the hard-wire signal, thereby controlling the vehicle collision in a timely and accurate manner. This ensures the timeliness and accuracy of vehicle collision control.
[0071] The present application also provides a vehicle collision control system, including: A collision signal acquisition unit, configured to acquire a collision signal of a vehicle; a collision signal processing unit for determining, based on the collision signal of the vehicle, whether the vehicle has collided and the direction of the collision; when it is determined that the vehicle has collided, determining the number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms based on the collision direction of the vehicle; generating a collision output signal based on the number of collision waveforms, the duration of each collision waveform, and the interval between adjacent collision waveforms; and transmitting the collision output signal to the collision association module; The collision association module is used to issue corresponding control instructions according to the collision output signal.
