[0025] The vehicle door 150 includes a door handle 151 and a door handle sensor 152, wherein the door handle sensor 152 is used to collect the rotation amplitude of the door handle 151 around a pivot. For example, the processor 110 can acquire the data collected by the door handle sensor 152, and when it is determined that the rotation amplitude of the door handle around the pivot reaches a certain value, it can control the vehicle door 150 to open.
[0026] Figure 2 A schematic flowchart of a door control method 200 provided in an embodiment of this application is shown. The method 200 can be executed by the vehicle 100; or, the method 200 can be executed by the processor 110; or, the method 200 can be executed by a system consisting of the processor 110 and the sensor 130. The method 200 includes:
[0027] S210, detected that a user inside the cabin pulled the first door handle.
[0028] Optionally, detecting a user pulling the first door handle inside the cabin includes: detecting the user pulling the first door handle inside the cabin based on data collected by the door handle sensor.
[0029] For example, the door handle sensor 152 can be used to collect the rotation amplitude of the door handle around its axis. When the user does not pull the door handle, the rotation amplitude is 0°; when the user pulls the door handle, the rotation amplitude is greater than 0°; when the user fully pulls the door handle, the rotation amplitude is 40°.
[0030] Optionally, based on the data collected by the door handle sensor, detecting the user's operation of pulling the first door handle in the cabin includes: determining that the user pulled the first door handle when it is determined from the data collected by the door handle sensor that the rotation amplitude is not 0.
[0031] Optionally, before detecting a user pulling the first door handle in the cabin, the method 200 further includes: determining that the vehicle speed is less than or equal to a preset speed, or determining that the vehicle is in a parked state.
[0032] For example, the preset speed is 10 km / h.
[0033] S220, during the process of the user pulling the first door handle, the first door is controlled to be in a closed state and data collected by the sensors outside the cabin is acquired, and the first door handle and the first door have a corresponding relationship.
[0034] For example, taking the first door handle as an example, the first door can be the door of the driver's side.
[0035] It should be understood that the door handles involved in the embodiments of this application can be door handles inside the cabin.
[0036] Optionally, the first door is located on the first side of the vehicle, and the acquisition of data collected by sensors outside the cabin includes: acquiring data collected by sensors on the first side.
[0037] For example, consider a first door handle located in the driver's area of the cabin, and a first door located in the driver's area (e.g., on the left side in the direction of vehicle travel). When a user in the driver's area pulls the door handle, the driver's area door can be controlled to be closed, and data collected by at least one of a camera, lidar, millimeter-wave radar, or ultrasonic radar in the left side of the vehicle can be acquired.
[0038] Based on the above technical solution, by activating the sensors on the outside of the vehicle cabin to collect data, the computational overhead when judging the collision risk between the door and the obstacle can be reduced, and the efficiency of collision risk detection can also be improved.
[0039] The above means that when the user in the driver's area pulls the door handle, the door in the driver's area can be kept closed. In other words, the door in the driver's area is locked when the user pulls the door handle for the first time.
[0040] The doors of the above vehicles cannot be opened when they are locked. The vehicle can open its doors when the doors are unlocked and the door handle rotation meets preset conditions.
[0041] For example, the preset condition includes the door handle's rotation amplitude reaching its maximum rotation amplitude (e.g., 40°).
[0042] S230, based on this data, controls the state of the first door.
[0043] Optionally, based on the data, the state of the first door is controlled, including: determining, based on the data, that there is no risk of collision between the first door and an obstacle outside the cabin before the first door handle is fully pulled; and controlling the first door to switch from a closed state to an open state when the first door handle is fully pulled.
[0044] For example, consider a user in the driver's side area. As the user pulls the door handle, the door handle sensor continuously monitors the rotation amplitude of the handle. For instance, during the time it takes for the door handle's rotation amplitude to change from 0° to 20°, the vehicle can keep the driver's side door closed and determine, based on data collected by sensors outside the cabin, that there is no risk of collision between the driver's side door and obstacles around the vehicle. When the door handle's rotation amplitude changes from 20° to 40°, the vehicle can control the driver's side door to switch from the closed state to the open state.
[0045] In this embodiment, when the user pulls the first door handle for the first time, the vehicle can control the first door corresponding to the first door handle to remain closed and acquire data collected by sensors outside the cabin. In other words, the time period during which the user first pulls the door handle can be used as a time period for determining whether there is a collision risk between the door and an obstacle based on data collected by the sensors. If, before the door handle reaches its maximum rotation amplitude, the data collected by the sensors determines that there is no collision risk between the first door and the obstacle, then when the door handle's rotation amplitude reaches its maximum, the vehicle can control the door to be open. Thus, collision risk detection between the door and the obstacle is completed during the initial pull of the door handle, and the door is opened when there is no collision risk, helping to avoid collisions between the door and surrounding obstacles after the door is opened. Simultaneously, since collision risk detection and door opening are achieved in a single pull of the door handle, user safety is ensured, and the tedious operation of repeatedly pulling the door handle is avoided.
[0046] In this embodiment, the method of detecting the collision risk between the car door and the obstacle is not specifically limited. For example, whether there is a collision risk between the car door and the obstacle can be determined by whether the predicted trajectory of the obstacle intersects with the trajectory of the car door's rotation.
[0047] The obstacles mentioned above can be dynamic obstacles (e.g., vehicles, motor vehicles, non-motor vehicles, etc.) or static obstacles (e.g., stone blocks, fences, etc.). This application embodiment does not specifically limit them.
[0048] Optionally, based on the data, the state of the first door is controlled, including: determining, based on the data, that there is a risk of collision between the first door and an obstacle outside the cabin before the first door handle is fully pulled; and controlling the first door to be locked.
[0049] For example, consider a user in the driver's side area. As the user pulls the door handle, the door handle sensor continuously monitors the rotation amplitude of the handle. For instance, if the vehicle determines, based on data from sensors outside the cabin, that the driver's side door poses a collision risk with surrounding obstacles after opening, the vehicle can lock the driver's side door before the handle reaches its maximum rotation amplitude. Thus, even if the driver's side door handle reaches its maximum rotation amplitude, the vehicle will not open the door.
[0050] Optionally, when no collision risk is detected between the first door and an obstacle outside the cabin, the first door is controlled to switch from a locked state to an unlocked state; when the user pulls the door handle again, the first door is controlled to switch from a closed state to an open state.
[0051] Optionally, the method 200 further includes: when controlling the first door to switch from a locked state to an unlocked state, controlling the speaker in the cabin to emit a prompt voice, the prompt voice being used to remind the user that the first door is in an unlocked state.
[0052] Optionally, based on the data, controlling the state of the first door includes: when it is determined based on the data that there is no risk of collision between the first door and an obstacle outside the cabin and the user pulls the first door handle again, controlling the first door to switch from a closed state to an open state.
[0053] For example, consider a user in the driver's side area. As the user pulls the door handle, the door handle sensor continuously monitors the rotation amplitude of the handle. For instance, during the time it takes for the door handle's rotation amplitude to change from 0° to 40°, the vehicle can keep the driver's side door closed and determine, based on data collected by sensors outside the cabin, whether there is a collision risk between the driver's side door and obstacles around the vehicle. If it is determined that there is no collision risk between the driver's side door and an obstacle, and the user pulls the first door handle again, the first door is opened from the closed state.
[0054] For example, detecting that the user pulls the first door handle again includes detecting that the rotation angle of the door handle changes from 0° to 40° again.
[0055] Optionally, based on the data, the state of the first door is controlled, including: when the first door handle is fully pulled, determining based on the data that there is a risk of collision between the first door and an obstacle outside the cabin; and controlling the first door to be locked.
[0056] For example, consider a user in the driver's side area. As the user pulls the door handle, the door handle sensor continuously monitors the rotation amplitude of the handle. For instance, if the vehicle determines a collision risk between the driver's side door and surrounding obstacles based on data collected by sensors outside the cabin during the period from 0° to 40°, the vehicle can lock the driver's side door when the rotation amplitude reaches its maximum. After detecting the user's first pull of the door handle, the vehicle can continuously monitor the collision risk between the door and surrounding obstacles using sensor data. When it is determined that there is no collision risk between the door and an obstacle, the user can be notified via a speaker inside the cabin that the driver's side door is unlocked. The user can then open the driver's side door by pulling the door handle.
[0057] In this embodiment, when the user pulls the first door handle for the first time, the vehicle can control the first door corresponding to the first door handle to remain closed and acquire data collected by sensors outside the cabin. That is, the time period during which the user first pulls the door handle can be used as a time period for determining whether there is a collision risk between the door and an obstacle based on the data collected by the sensors. If, during the initial pulling of the door handle, the data collected by the sensors determines that there is no collision risk between the first door and the obstacle, then during the user's second pulling of the door handle, the vehicle can control the door to be open. In this way, the collision risk detection between the door and the obstacle is completed during the initial pulling of the door handle. When it is determined that there is no collision risk between the door and the obstacle and the user pulls the door handle a second time, the door can be controlled to open, which helps to avoid collisions between the door and surrounding obstacles after the door is opened, thus improving the user's driving safety.
[0058] Optionally, based on the data, the state of the first door is controlled, including: when it is determined based on the data that there is a risk of collision between the first door and an obstacle outside the cabin, the first door is kept closed.
[0059] For example, if the vehicle determines, based on data collected by sensors outside the cabin, that there is a risk of collision between the driver's side door and obstacles around the vehicle during the time it takes for the door handle to rotate from 0° to 40°, then the vehicle can keep the driver's side door closed when the door handle reaches its maximum rotation value; or, the vehicle can keep the driver's side door locked before the door handle reaches its maximum rotation value.
[0060] Optionally, the method 200 further includes: controlling the speakers in the cockpit to emit an alarm sound; and / or controlling the ambient lights in the cockpit to illuminate.
[0061] For example, when the vehicle determines, based on data collected by sensors outside the cabin, that there is a risk of collision between the driver's side door and an obstacle around the vehicle, it can control the ambient lighting in the driver's side area to turn red, or control the speakers in the driver's side area to emit a warning sound.
[0062] Optionally, the method 200 further includes: when a collision risk is detected between the first door and an obstacle outside the cabin and the user pulls the door handle again, controlling the first door to switch from a closed state to an open state.
[0063] In this embodiment, when a collision risk is detected between the vehicle door and an obstacle, the door can be kept closed. Once the non-collision risk between the door and the obstacle is eliminated, the user can open the door by pulling the door handle. This helps avoid collisions between the door and surrounding obstacles after it is opened, thus improving the user's driving safety.
