Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle emergency escape technology, and in particular to a vehicle control method, device, electronic equipment, chip, and medium. Background Technology
[0002] When a collision is unavoidable during driving, collision sensors transmit acceleration or pressure signals to the Airbag Control Unit (ACU). The ACU then issues an ignition current to deploy airbags, curtain airbags, seatbelt pretensioners, and other restraint and protective devices to protect occupants from impact injuries. Simultaneously, the ACU transmits collision information to the Electronic Control Unit (ECU) via the Controller Area Network (CAN) bus and the Event Notification Signal (ENS). This ECU executes actions such as cutting off engine fuel, deactivating the high-voltage circuit, unlocking doors, activating hazard lights, and making an emergency call (E-Call) to ensure occupants' safety and facilitate timely escape, as well as rescue by external personnel. However, in medium- to high-speed collisions, there is a probability that the doors may be damaged and unable to be opened, hindering occupant escape. Summary of the Invention

[0044] Figure 10 This is a schematic diagram of the chip structure according to an embodiment of the present disclosure. Detailed Implementation
[0045] Embodiments of this disclosure are described in detail below, with examples of embodiments shown in the accompanying drawings, wherein the same or similar reference numerals identify the same or similar originals or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.
[0046] When a collision is unavoidable during driving, the collision sensor transmits signals such as acceleration or pressure to the ACU, which then sends an ignition current to deploy restraint and protection devices such as airbags, curtain airbags, and seat belt pretensioners to protect occupants from impact injuries. At the same time, the ACU transmits collision information to the vehicle's strongly correlated ECU via the CAN bus and collision hardline ENS, executing actions such as engine fuel cut-off, high-voltage power-off, door unlocking, hazard lights activation, and E-Call to protect occupants' lives, ensure timely escape, and facilitate rescue by external personnel.
[0047] However, in medium- and high-speed collisions, there is a certain probability that the door unlocking will fail, the door handle will not pop out, or the door hinges will deform and prevent the door from opening, which may affect the escape of passengers. The automatic opening of the windows and sunroof after a collision is an excellent way to optimize and supplement the escape of passengers or external rescue.
[0048] The method proposed in this disclosure is applied to vehicle emergency escape and can be applied to scenarios of vehicle collisions in the fields of occupant driving, assisted driving, and autonomous driving. The application scenarios are not limited in the embodiments of this disclosure.
[0049] The vehicle control method provided in this application will be described in detail below with reference to the accompanying drawings.
[0050] Figure 1 This is a flowchart illustrating a vehicle control method according to an embodiment of this disclosure. The method is executed by a vehicle controller or a server. Figure 1 The vehicle control method shown in the embodiment includes:
[0051] Step 101: Obtain the collision data and / or first speed of the target vehicle.
[0052] In this embodiment, the collision data is collected by collision sensors deployed on the target vehicle's body. These collision sensors can be acceleration sensors, pressure sensors, or internal collision sensors within the airbag controller, such as ball collision sensors, wheel collision sensors, eccentric hammer collision sensors, mercury switch collision sensors, resistance strain gauge collision sensors, and piezoelectric effect collision sensors. The collision sensors record the intensity and direction of the collision. The vehicle controller coordinates the operation of all vehicle controllers, including the airbag controller, door control unit (DCU), sunroof controller, ECU, etc. When a vehicle collision occurs, the vehicle controller collects collision data through collision sensors deployed on the vehicle body or in the airbags, or records the vehicle speed at the time of the collision as the first vehicle speed.
[0053] Step 102: Based on the collision data, determine the first collision type using the collision model.
[0054] In this embodiment, the first collision type is the collision type determined by the vehicle controller or server based on the analysis of the current collision data, including frontal collision, side collision, rollover collision, and angled collision. Based on the recorded collision data, the vehicle controller or server can analyze the currently occurring collision type according to the constructed collision model.
[0055] Step 103: Generate control commands based on the first collision type and / or the first vehicle speed. The control commands are used to control the windows and / or sunroof in the target vehicle.
[0056] In this embodiment, control commands are generated based on the first collision type that has occurred and / or the first vehicle speed recorded at the time of the collision, to control the window controller and / or sunroof controller of the target vehicle. If the window controller of the target vehicle is controlled, the control motor is executed to determine whether to drive the window to open. If the sunroof controller of the target vehicle is controlled, the control motor is executed to determine whether to drive the sunroof to open, providing an escape route for occupants.
[0057] In this embodiment, the decision on whether to determine the handling plan is made by the vehicle controller or the server, depending on the extent of the collision damage to the vehicle. If the vehicle's electronic control or network modules are damaged, causing a communication breakdown between the vehicle and the server, the vehicle controller determines the handling plan. If the vehicle and the server can establish normal network communication, the server determines the handling plan.
[0058] In summary, the vehicle control method proposed in this disclosure acquires collision data and a first vehicle speed, providing a data foundation for determining the collision type; based on the collision data, the first collision type is determined through a collision model, providing a basis for whether the windows and / or sunroof should be opened; based on the first collision type and / or the first vehicle speed, control commands are generated to control the windows and / or sunroof in the target vehicle to determine whether the control motor should drive the windows and / or sunroof to open, providing different emergency measures for different collisions, especially providing an escape route through the windows or sunroof for occupants.
[0059] Figure 2 This is a flowchart illustrating how a first collision type is determined using a collision model based on collision data, according to an embodiment of this disclosure. Figure 2 Yes Figure 1 Step 102 will be further explained based on Figure 2 The illustrated embodiment includes the following steps:
[0060] Step 201: Based on the collision data, calculate the similarity with the collision data corresponding to different preset collision types in the collision model.
[0061] In this embodiment, collision data is analyzed using a collision model deployed in the vehicle's controller. This collision model includes models for various types of collisions. The similarity between the collision data and the collision data corresponding to different preset collision types in the collision model is calculated to determine the collision type of the current collision data.
[0062] Step 202: Determine the collision type corresponding to the highest similarity value as the first collision type, wherein the first collision type is one of frontal collision, side collision, roll collision and angle collision.
[0063] In this embodiment, the similarity between collision data and collision models corresponding to different preset collision types is calculated. The highest similarity value is found from the similarity values corresponding to each collision model, and the collision type corresponding to the highest similarity value is taken as the first collision type. The first collision type includes frontal collision, side collision, rollover collision, and angled collision. A frontal collision is when the front or rear end of a vehicle collides with another vehicle or a fixed object; a side collision is when both sides of a vehicle collide; a rollover collision is when a vehicle rolls over after being subjected to a huge impact force; and an angled collision is when a vehicle collides with another vehicle or object at a certain angle, while the side of the vehicle rotates to a certain extent in the horizontal direction.
[0064] Figure 3 This is a flowchart illustrating how control commands are generated based on a first collision type and / or a first vehicle speed, according to an embodiment of this disclosure. Figure 3 Yes Figure 1Step 103 will be further explained based on Figure 3 The illustrated embodiment includes the following steps:
[0065] Step 301: If the first collision type is a side collision, then execute the first control command, wherein the first control command refers to controlling the motor to drive the windows and / or sunroof to immediately perform the opening function.
[0066] In this embodiment, after the collision data is analyzed by the vehicle controller, if the first collision type is determined to be a side collision, then the first control command is executed. The first control command is to control the motor to drive the windows and / or sunroof to immediately open.
[0067] Step 302: If the first collision type is not a side collision, determine whether to control the motor to drive the windows and / or sunroof to perform the opening function based on the first collision type and the first vehicle speed.
[0068] In this embodiment, after the collision data is analyzed by the vehicle controller, if the first collision type is not a side collision, then based on the first collision type and the first vehicle speed, it is further determined whether to control the motor to drive the windows and / or sunroof to perform the opening function.
[0069] In this embodiment, the first collision type is divided into side collision and non-side collision. For side collisions, regardless of the vehicle speed, the motor is controlled to open the windows and / or sunroof. When the first collision type is not a side collision, the decision to open the windows and / or sunroof is determined based on the vehicle speed.
[0070] Figure 4 This is a flowchart illustrating an embodiment of the present disclosure, in which, if the first collision type is not a side collision, a process is used to determine whether to control the motor to drive the windows and / or sunroof to perform the opening function based on the first collision type and the first vehicle speed. Figure 4 Yes Figure 3 Step 302 will be explained in detail, based on Figure 3 The illustrated embodiment includes the following steps:
[0071] Step 401: If the first collision type is a frontal collision and the first vehicle speed is greater than or equal to the first threshold, then execute the first control command.
[0072] In this embodiment, if the first collision type is a frontal collision and the first vehicle speed is greater than or equal to the first threshold, indicating that the vehicle has suffered a serious collision, then the first control command is executed, that is, the motor is controlled to drive the windows and / or sunroof to immediately perform the opening function.
[0073] Step 402: If the first collision type is a frontal collision and the first vehicle speed is less than the first threshold, then execute the second control command. The second control command means controlling the motor not to drive the windows and sunroof to perform the opening function.
[0074] In this embodiment, if the first collision type is a frontal collision and the first vehicle speed is lower than the first threshold, preferably 15 km / h, then since the current vehicle speed is very slow, it can be determined to be a minor collision caused by a common scrape. In this case, the second control command is executed, that is, the motor is controlled not to drive the windows and sunroof to perform the opening function.
[0075] This embodiment proposes different control methods for whether the windows and / or sunroof are open in frontal collisions at different vehicle speeds. For side collisions at different vehicle speeds, it is necessary to determine a control method for whether the windows and / or sunroof are open.
[0076] Figure 5 This is a flowchart illustrating an embodiment of the present disclosure, in which, if the first collision type is not a side collision, a process is used to determine whether to control the motor to drive the windows and / or sunroof to perform the opening function based on the first collision type and the first vehicle speed. Figure 5 Yes Figure 3 Step 302 will be explained in detail, based on Figure 5 The illustrated embodiment includes the following steps:
[0077] Step 501: If the first collision type is a rollover collision and the first vehicle speed is less than or equal to the second threshold, then execute the third control command. The third control command refers to controlling the motor to drive the windows and / or sunroof to open after a first delay.
[0078] In this embodiment, if the first collision type is a rollover collision, and the first vehicle speed is less than or equal to a second threshold, preferably 64 km / h, then a third control command is executed. Specifically, the motor is controlled to drive the windows and / or sunroof to open after a first delay. Preferably, the first delay is 8 to 10 seconds. By delaying the opening of the windows and / or sunroof after this first delay, occupants are protected during the vehicle rollover process, preventing them from being ejected and suffering greater injury.
[0079] Step 502: If the first collision type is a rollover collision and the first vehicle speed is greater than the second threshold, then execute the second control command.
[0080] In this embodiment, if the first collision type is a rollover collision and the first vehicle speed is greater than the second threshold, then the second control command is executed, that is, the motor is controlled not to drive the windows and sunroof to perform the opening function, so as to prevent the user from being thrown out of the vehicle during a violent rollover.
[0081] In this embodiment, when the first collision type is a rollover collision, at a low to medium vehicle speed, the motor is delayed in controlling the windows and / or sunroof to open. In other words, this ensures that the windows and / or sunroof open after the vehicle rolls to a stop, allowing users to escape. At a high vehicle speed, the windows and sunroof remain closed to prevent occupants from being ejected from the vehicle.
[0082] Figure 6 This is a flowchart illustrating an embodiment of the present disclosure, in which, if the first collision type is not a side collision, a process is used to determine whether to control the motor to drive the windows and / or sunroof to perform the opening function based on the first collision type and the first vehicle speed. Figure 6 Yes Figure 4 and Figure 3 Step 302 will be explained in detail, based on Figure 6 The illustrated embodiment includes the following steps:
[0083] Step 601: If the first collision type is an angled collision and the first vehicle speed is less than the first threshold, then execute the second control command.
[0084] In this embodiment, if the first collision type is an angled collision and the first vehicle speed is less than the first threshold, then since the current vehicle speed is very slow, it can be determined to be a minor collision caused by a common scrape, and the second control command is executed, that is, the motor is controlled not to drive the windows and sunroof to perform the opening function.
[0085] Step 602: If the first collision type is an angled collision and the first vehicle speed is greater than or equal to the first threshold, then execute the first control command.
[0086] In this embodiment, if the first collision type is an angled collision and the first vehicle speed at the time of the collision is greater than or equal to the first threshold, then the first control command is executed, that is, the motor is controlled to drive the windows and / or sunroof to immediately perform the opening function, thereby providing the occupants with windows and / or sunroof as an escape route after the collision ends.
[0087] In this embodiment, if the first collision type is not a side collision but an angled collision, different control commands are executed according to the first vehicle speed. This ensures that the vehicle's windows and sunroof will not open during a minor collision, but can open immediately when a collision occurs at a higher speed, providing a rescue or escape route for the occupants.
[0088] Figure 7This is a schematic diagram illustrating the information transmission between various devices during a vehicle collision, according to an embodiment of this disclosure. In this embodiment, collision sensor 1, collision sensor 2, ..., collision sensor n deployed on the vehicle body continuously collect data. When a vehicle collision occurs, the ACU is triggered to deploy the airbags to protect the occupants. Simultaneously, control commands for the windows and / or sunroof are sent to the DCU and / or ECU via the CAN bus to determine whether to control the motor to drive the windows and / or sunroof to perform the opening function.
[0089] The collision intensity detection determines the specific operating conditions and the response matrix of the windows and / or sunroof, as shown in the table below:
[0090]
[0091] In this embodiment of the disclosure, the frontal collision conditions include full frontal collision, offset collision, pole collision, and rear collision; the side collision conditions include barrier collision and pole collision; and the angled collision condition is an angled collision. Specifically, the frontal collision conditions in the automotive crash test standard include full frontal collision, offset collision, pole collision, and rear collision. A full frontal collision refers to a collision with a vehicle or object with no angle and full contact; an offset collision refers to a collision with a vehicle or object with no angle and partial contact; a pole collision refers to a collision with a cylinder; and a rear collision refers to a collision between the rear end of the vehicle and a vehicle or object. The side collision conditions in the automotive crash test standard include barrier collision and pole collision. A barrier is a movable and deformable barrier used to simulate common vehicle-to-vehicle collisions at intersections. The angled collision conditions in the automotive crash test standard include an angled collision, which refers to a collision with a vehicle or object at a certain angle, while the side of the vehicle rotates to a certain extent in the horizontal direction.
[0092] When the collision sensor detects a frontal collision, the ACU transmits the information to the DCU and sunroof controller via the CAN bus and collision hardline ENS, and the drive motor immediately executes the opening functions of the four doors and the sunroof.
[0093] When the collision sensor detects a side collision, the ACU transmits the information to the DCU and sunroof controller via the CAN bus and collision hardline ENS, and the drive motor immediately executes the opening functions of the four doors and the sunroof.
[0094] When the collision sensor detects a rollover collision, the ACU transmits the information to the DCU and sunroof controller via the CAN bus and collision hardline ENS. The drive motor then executes the opening functions of the four doors and the sunroof after a delay of 8 to 10 seconds.
[0095] When the collision sensor detects a collision at a specific angle, the ACU transmits this information to the DCU and sunroof controller via the CAN bus and the collision hardline ENS, and the drive motor immediately executes the opening functions of the four doors and the sunroof.
[0096] In summary, the vehicle control method proposed in this disclosure acquires collision data and a first vehicle speed, providing a data basis for determining the collision type; based on the collision data, it determines the first collision type through a collision model, providing a basis for whether the windows and / or sunroof should be opened; and based on the first collision type and / or the first vehicle speed, it determines whether to control the motor to drive the windows and / or sunroof to open, providing different emergency measures for different collisions, especially providing an escape route for occupants through the windows or sunroof.
