Fig. 4 shows an auxiliary device for a vehicle according to an embodiment of the invention. The auxiliary device 300 shown in fig. 4 may be used with the vehicle 30.
The auxiliary device 300 may include a communication unit 310 and an adjustment unit 320. The communication unit 310 and the adjustment unit 320 are communicatively coupled.
The communication unit 310 is configured to receive information about traffic accidents within an associated road area of the vehicle from the server. As described above, the associated road area of the vehicle may include at least one of: the road area where the vehicle is currently located, the road area where the vehicle is going to travel. The road area in which the vehicle is currently located may be determined by any suitable means, such as, but not limited to, by GNSS or RTK techniques. The road area through which the vehicle is to travel and the road area to which the vehicle is to travel may be determined, for example, but not limited to, according to a navigation planning path of the vehicle. Depending on the situation, the associated road area of the vehicle may be determined by the vehicle itself and provided to the server, or may be determined by the server and retrieved therefrom. In the former case, the communication unit 310 may also be configured to provide the associated road area of the vehicle to the server. Information about traffic accidents within the associated road area of the vehicle may be obtained by the server based on traffic accident-related information collected and stored in advance.
The adjustment unit 320 is configured to adjust the safety-related parameters of the vehicle based on the information received by the communication unit 310 from the server.
The information received by the communication unit 310 from the server regarding the traffic accident in the associated road area of the vehicle may include information indicating one or more traffic accident types in the associated road area. In this case, the adjustment unit 320 may be configured to adjust a safety-related parameter of the vehicle associated with the traffic accident type based on the traffic accident type.
The information received by the communication unit 310 from the server regarding the traffic accident in the associated road area of the vehicle may further include information indicating the frequency of occurrence of at least one of the one or more traffic accident types in the associated road area. In this case, the adjustment unit 320 may be further configured to adjust, for each of the at least one traffic accident type, a safety-related parameter of the vehicle associated with the traffic accident type by an adjustment amount based on the occurrence frequency of the traffic accident type. As described above, for each of the at least one traffic accident types, the frequency of occurrence thereof may include one or both of: the total frequency of occurrence of the traffic accident type within the associated road area over a period of time; the frequency of recent occurrences of the traffic accident type within the associated road area within the most recent predetermined time period.
For example, in one embodiment, the information received by the communication unit 310 from the server indicates the type of traffic accident within the associated road area of the vehicle and its frequency of occurrence as follows:
three traffic accident types: rear-end collision accident, lane change accident, vehicle-rider accident;
total frequency of occurrence of these three traffic accident types over the past 1 day: 0.8 start/day of rear-end collision accident, 4.1 start/day of lane change accident, and 3.5 start/day of vehicle-cyclist accident;
recent occurrence frequencies of three traffic accident types, 60 minutes recently: 4.5 starts/day of rear-end collision accident, 3.7 starts/day of lane change accident, and 8.8 starts/day of vehicle-rider accident.
In this embodiment, the traffic accident type includes a rear-end collision accident, and the safety-related parameter associated with the rear-end collision accident may include a safety longitudinal distance between the vehicle and an adjacent preceding vehicle in front of the vehicle. The adjustment unit 320 may increase the value of the safe longitudinal distance between the vehicle and the adjacent preceding vehicle in front of it.
In this embodiment, the traffic accident type includes a lane change accident, and the safety-related parameter associated with the lane change accident may include a safety threshold associated with the vehicle issuing a lane change notice or performing a lane change. The safety threshold may include, for example, but is not limited to: a safe distance threshold between the vehicle and a void on its target lane, a safe distance threshold between the vehicle and an adjacent rear vehicle on its target lane, a safe speed threshold of an adjacent rear vehicle on the target lane of the vehicle. For example, the adjustment unit 320 may decrease the safe distance threshold between the vehicle and the void on its target lane and the safe speed threshold of the adjacent rear vehicle on the target lane of the vehicle, and increase the safe distance threshold between the vehicle and the adjacent rear vehicle on its target lane.
In this embodiment, the traffic accident type comprises a vehicle-rider accident, and the safety-related parameter associated with the vehicle-rider accident may comprise a safety lateral distance and/or a safety longitudinal distance between the vehicle and the rider around it detected. For example, the adjustment unit 320 may increase the value of the safe lateral distance and/or the safe longitudinal distance.
For any safety-related parameter, the amount of adjustment (increase or decrease) by which the adjustment unit 320 adjusts may be based on the overall frequency of occurrence and/or the frequency of recent occurrence of the associated traffic accident type. For example, the adjustment amount may be equal to a weighted sum of the total frequency of occurrence and the recent frequency of occurrence of the associated traffic accident type. In this case, the weight given to the recent occurrence frequency may be higher than the weight given to the total occurrence frequency.
In addition, for any safety-relevant parameter, a suitable adjustment range can be set for it, so as to avoid excessive adjustment.
Fig. 5 shows an auxiliary device for a vehicle according to another embodiment of the present invention. The auxiliary device 300' shown in fig. 5 may be used with the vehicle 30.
With respect to the apparatus 300 of fig. 4, the apparatus 300' further comprises a providing unit 330. The providing unit 330 may be communicatively coupled with the adjusting unit 320.
The providing unit 330 is configured to provide the safety-related parameter adjusted by the adjusting unit 320 to a driver of the vehicle or an automated driving system. In this way, the driver or the autopilot system of the vehicle can control and drive the vehicle in accordance with the adjusted safety-related parameters.
