The ride assist system according to the present disclosure is preferably applied to a vehicle having an autonomous driving mode. Accordingly, the present disclosure relates to a vehicle, preferably an autonomous vehicle, comprising a ride-assist system of the present disclosure.
The vehicle with autonomous driving mode described herein has the following basic features: for example, such vehicles are mounted with a plurality of sensors or positioning devices, such as an image pickup device, a laser radar, a millimeter wave radar, an ultrasonic sensor, a vehicle networking communication (V2X) device, a High Automated Driving (HAD) map, and the like, which are capable of detecting the environment around the vehicle such as surrounding objects, obstacles, infrastructure, and the like; these vehicles are able to detect the location of the current vehicle through Global Navigation Satellite System (GNSS) and one or a combination of sensor detection and HAD maps; the vehicles can obtain a new navigation route through the online server; these vehicles are able to plan a route to be traveled based on the perception and location results; such vehicles can also send control signals to the powertrain, steering system, braking system, etc. based on the planned route.
Fig. 1 schematically illustrates an assisted ride system 100 according to an embodiment of a first aspect of the disclosure. The system 100 includes an information acquisition unit 110, a computation unit 120, and an execution unit 130, and each unit is communicatively coupled to each other.
In fig. 1, the information acquiring unit 110 may be configured to acquire position information of a passenger including an initial position and a real-time position of the passenger and position information of a vehicle including the initial position and the real-time position of the vehicle. Preferably, the information acquiring unit is configured to continuously acquire the position information of the passenger and the position information of the vehicle at a frequency when the vehicle is less than a distance from an initial position of the passenger. In one example, the information acquisition unit acquires the position information of the passenger through a handheld device of the passenger. The handheld device may be a smartphone, a tablet computer, a smartwatch, and/or smart glasses. In one example, the location of the passenger may be obtained in real-time via a Global Navigation Satellite System (GNSS), Wi-Fi, and a base station. For example, a smart phone typically has a positioning function, and a user position can be located in real time by retrieving positioning data of, for example, a Global Positioning System (GPS) sensor built in the phone. In one example, the information acquisition unit acquires the position information of the vehicle through a positioning device on the vehicle. For example, the positioning data of its global navigation satellite system may be acquired by an in-vehicle navigation device on the vehicle.
In one embodiment, the information acquisition unit 110 is located on the vehicle, and the position information of the passenger can be sent to a server, such as a cloud server. The information acquisition unit 110 acquires the position information of the passenger from the server. For example, the information acquisition unit acquires the position information of the passenger and/or the position information of the vehicle by wireless communication. In another embodiment, the information obtaining unit 110 is on a server, such as a cloud server. The passenger's location information and/or the vehicle's location information may be transmitted to a server, for example, by wireless communication. Wireless communications include, but are not limited to: mobile phone network, Wi-Fi, Bluetooth.
In fig. 1, the calculation unit 120 may be configured to calculate an estimated time required for the vehicle to reach the initial position of the passenger based on at least the initial position of the passenger and the initial position of the vehicle, calculate an estimated distance of the passenger from the initial position according to the estimated time; and for re-planning a route of the vehicle to the passenger based on the real-time location of the passenger and the real-time location of the vehicle. The estimated time required for the vehicle to reach the initial position of the passenger may be determined by a navigation route for the vehicle to reach the initial position of the passenger, for example by a navigation device of the vehicle. For example, a navigation route requires N seconds of time for the vehicle to travel along the navigation route. If the passenger continues to walk, rather than waiting on site, the passenger may have been at a distance from their initial position as the vehicle approaches the passenger's initial position. The estimated distance of the passenger from the initial position is proportional to the estimated time required for the vehicle to reach the passenger's initial position. The estimated distance of the passenger from the initial position is also related to the walking speed of the person. The estimated distance is allowed to have errors and may vary within a range, for example, between 50% and 200% of the estimated distance. For example, assuming 1 meter per second of travel, the estimated distance of the passenger from the initial position is N meters. When the vehicle is less than the estimated distance (i.e., 0.5N to 2N meters, for example, N meters) from the initial position of the passenger, the real-time position of the passenger and the real-time position of the vehicle are acquired by the information acquisition unit 110, and the route from the vehicle to the passenger is re-planned. For example, a route of the vehicle to the passenger is acquired by a navigation device of the vehicle.
In fig. 1, the execution unit 130 may be configured to cause the vehicle to travel to the initial position of the passenger until the distance to the initial position of the passenger is less than the estimated distance; then, based on the vehicle's route to the passenger continuing to be re-planned at a frequency, causing the vehicle to travel along the re-planned route, continuously approaching the passenger; and in response to the separation of the relative positions of the vehicle and the passenger being less than a threshold, issuing an indication or instruction to the passenger and the vehicle that the passenger is boarding. The distance of the vehicle from the initial position of the passenger may be determined on a navigation route traveled by the vehicle. In one example, the vehicle is driven by a driver, and an indication of travel along the navigation route is sent to the driver. In another embodiment, the vehicle is an autonomous vehicle, and the vehicle is sent instructions to travel along the navigation route. When the vehicle is less than the estimated distance (i.e., 0.5N to 2N meters, for example, N meters) from the initial position of the passenger, the real-time position of the passenger and the real-time position of the vehicle are acquired by the information acquisition unit 110, and the route from the vehicle to the passenger is re-planned. For example, a route of the vehicle to the passenger is acquired by a navigation device of the vehicle. The frequency may be once every 2 minutes, once every minute, or once every 30 seconds. The higher the frequency, the more accurate the planned route of the vehicle to the passenger. Preferably, the frequency is progressively greater, the closer to the passenger, the more accurate the planned route of the vehicle to the passenger. The relative position of the vehicle and the passenger is suitable for the passenger to get on the vehicle, the vehicle stops, the door lock is opened, and the passenger gets on the vehicle. The threshold distance of the vehicle from the passenger may be 20 meters, 10 meters, or 5 meters.
The execution unit 130 may be on the vehicle, or may be on a server. In one example, the execution unit 130 issues an instruction or instruction to the vehicle to prepare for the passenger to board, and an instruction to board is issued by the vehicle to the passenger. The execution unit 130 instructs the vehicle to park and unlock the door lock. The vehicle may indicate boarding to the passenger by sound and/or light. The vehicle may also send an indication of boarding to the passenger's handheld device, such as a cell phone, via V2X. In another example, the execution unit 130 issues an instruction or instruction to the vehicle to prepare for the passenger to board, and issues an instruction to the passenger to board. The execution unit 130 instructs the vehicle to park and unlock the door lock; and send an indication of boarding to the passenger's handheld device, such as a cell phone.
It should be understood that the various elements of the system 100 of the present disclosure may be implemented in whole or in part by software, hardware, firmware, or a combination thereof. The units may be embedded in a processor of the computer device in a hardware or firmware form or independent of the processor, or may be stored in a memory of the computer device in a software form for being called by the processor to execute operations of the units. Each of the units may be implemented as a separate component or module, or two or more units may be implemented as a single component or module.
It will be appreciated by those of ordinary skill in the art that the schematic diagram of the system 100 shown in fig. 1 is merely an illustrative block diagram of portions of structure associated with aspects of the present disclosure and does not constitute a limitation of the computer devices, processors, or computer programs embodying aspects of the present disclosure. A particular computer device, processor or computer program may include more or fewer components or modules than shown in the figures, or may combine or split certain components or modules, or may have a different arrangement of components or modules.
A ride assist method according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings. Fig. 2 is a flow chart illustrating a ride assist method S100 according to an embodiment of the disclosure. The ride assist method S100 is performed by the ride assist system 100 described above.
As shown in fig. 2, the ride-assist method S100 includes: step S110, acquiring initial positions of passengers and initial positions of vehicles; step S120, calculating the estimated time required for the vehicle to reach the initial position of the passenger at least based on the initial position of the passenger and the initial position of the vehicle, and calculating the estimated distance between the passenger and the initial position according to the estimated time; a step S130 of causing the vehicle to travel to an initial position of the passenger until a distance from the initial position of the passenger is less than the estimated distance; step S140, continuously acquiring the real-time position of the passenger and the real-time position of the vehicle at a frequency, replanning the route from the vehicle to the passenger based on the real-time position of the passenger and the real-time position of the vehicle, and enabling the vehicle to travel along the replanned route to be continuously close to the passenger based on the replanned route from the vehicle to the passenger; step S150, responding to the distance between the relative positions of the vehicle and the passenger being smaller than a threshold value, and sending an instruction or instruction of getting on the vehicle to the passenger and the vehicle.
In S110, the initial position of the passenger and the initial position of the vehicle are acquired. In one example, the passenger's location information may be obtained via the passenger's handheld device. The handheld device may be a smartphone, a tablet computer, a smartwatch, and/or smart glasses. For example, the location of the passenger may be obtained in real time via a Global Navigation Satellite System (GNSS), Wi-Fi, and a base station. For example, a smart phone typically has a positioning function, and a user position can be located in real time by retrieving positioning data of, for example, a Global Positioning System (GPS) sensor built in the phone. In one example, the location information of the vehicle may be obtained by a locating device on the vehicle. For example, the positioning data of its global navigation satellite system may be acquired by an in-vehicle navigation device on the vehicle. In one embodiment, the passenger location information may be sent to a server, such as a cloud server, from which the passenger location information is obtained. For example, the information acquisition unit acquires the position information of the passenger and/or the position information of the vehicle by wireless communication. In another embodiment, the passenger location information and/or the vehicle location information may be transmitted to a server, such as a cloud server, for example, via wireless communication. Wireless communications include, but are not limited to: mobile phone network, Wi-Fi, Bluetooth.
In S120, an estimated time required for the vehicle to reach the initial position of the passenger is calculated based on at least the initial position of the passenger and the initial position of the vehicle, and an estimated distance from the initial position of the passenger is calculated from the estimated time. The estimated time required for the vehicle to reach the initial position of the passenger may be determined by a navigation route for the vehicle to reach the initial position of the passenger, for example by a navigation device of the vehicle. For example, a navigation route requires N seconds of time for the vehicle to travel along the navigation route. If the passenger continues to walk, rather than waiting on site, the passenger may have been at a distance from their initial position as the vehicle approaches the passenger's initial position. The estimated distance of the passenger from the initial position is proportional to the estimated time required for the vehicle to reach the passenger's initial position. The estimated distance of the passenger from the initial position is also related to the walking speed of the person. The estimated distance is allowed to have errors and may vary within a range, for example, between 50% and 200% of the estimated distance. For example, assuming 1 meter per second of travel, the estimated distance of the passenger from the initial position is N meters.
In S130, the vehicle is caused to travel toward the initial position of the passenger until the distance from the initial position of the passenger is less than the estimated distance. The distance of the vehicle from the initial position of the passenger may be determined on a navigation route traveled by the vehicle. In one example, the vehicle is driven by a driver, and an indication of travel along the navigation route is sent to the driver. In another embodiment, the vehicle is an autonomous vehicle, and the vehicle is sent instructions to travel along the navigation route.
In S140, a real-time location of a passenger and a real-time location of a vehicle are continuously obtained at a frequency, a route of the vehicle to the passenger is re-planned based on the real-time location of the passenger and the real-time location of the vehicle, and the vehicle is caused to travel along the re-planned route, continuously approaching the passenger, based on the re-planned route to the passenger. Acquiring the real-time position of the passenger and the real-time position of the vehicle may be as described in S110. In one example, the route of the vehicle to the passenger may be obtained by a navigation device of the vehicle. The frequency may be once every 2 minutes, once every minute, or once every 30 seconds. The higher the frequency, the more accurate the planned route of the vehicle to the passenger. Preferably, the frequency is progressively greater, the closer to the passenger, the more accurate the planned route of the vehicle to the passenger. In one embodiment, the passenger location information may be sent to a server, such as a cloud server, from which the passenger location information is obtained. For example, the information acquisition unit acquires the position information of the passenger and/or the position information of the vehicle by wireless communication. In another embodiment, the passenger location information and/or the vehicle location information may be transmitted to a server, such as a cloud server, for example, via wireless communication. Wireless communications include, but are not limited to: mobile phone network, Wi-Fi, Bluetooth.
In S150, and in response to the distance between the relative positions of the vehicle and the passenger being less than a threshold, an indication or instruction is issued to the passenger and the vehicle that the passenger is boarding. The relative position of the vehicle and the passenger is suitable for the passenger to get on the vehicle, the vehicle stops, the door lock is opened, and the passenger gets on the vehicle. The threshold distance of the vehicle from the passenger may be 20 meters, 10 meters, or 5 meters. In one example, an indication or instruction is issued to the vehicle in preparation for the passenger to board, and an indication to board is issued by the vehicle to the passenger. The vehicle may indicate boarding to the passenger by sound and/or light. The vehicle may also send an indication of boarding to the passenger's handheld device, such as a cell phone, via V2X. In another example, an instruction or instruction to prepare a passenger to board is issued to the vehicle, and an instruction to board is issued to the passenger. For example, instructing the vehicle to park, unlocking the door lock; and send an indication of boarding to the passenger's handheld device, such as a cell phone.
