Vehicle stop position determination system and vehicle stop position determination method
View Patent ↗A vehicle stop position determination system includes an environmental sensor, a vehicle sensor and a processor. The environmental sensor is configured to detect traveling environment of a host vehicle to collect traveling environment data. The vehicle sensor is configured to detect driving status of the host vehicle to collect driving status data. The processor is configured to determine, as a stop position for a road intersection, a position of the host vehicle at a timing when the driving status data indicates that the host vehicle is stopping and the traveling environment data indicates a predetermined condition based on a relative position of the host vehicle relative to the road intersection.
1 . A vehicle stop position determination system comprising:
an environmental sensor configured to detect traveling environment of a host vehicle to collect traveling environment data;
a vehicle sensor configured to detect driving status of the host vehicle to collect driving status data;
a processor configured to determine, as a stop position for a road intersection, a position of the host vehicle at a timing when the driving status data indicates that the host vehicle is stopping and the traveling environment data indicates a predetermined condition based on a relative position of the host vehicle relative to the road intersection; and
a computer memory configured to store stop positions for the road intersection to calculate an optimal stop position for the road intersection based on the stop positions stored in the computer memory, the stop positions being at least partially determined by the processor.
2 . The vehicle stop position determination system according to claim 1 , wherein
the predetermined condition is determined based on whether the host vehicle is positioned inside the road intersection.
3 . The vehicle stop position determination system according to claim 1 , wherein
the environmental sensor is configured to detect a traffic light ahead of the host vehicle, and
the predetermined condition includes a condition that the color of the traffic light is red.
4 . The vehicle stop position determination system according to claim 3 , wherein
the environmental sensor is further configured to detect a leading vehicle in front of the host vehicle, and
the predetermined condition further includes a condition that no leading vehicle is present.
5 . The vehicle stop position determination system according to claim 1 , wherein
the environmental sensor is configured to detect an oncoming vehicle traveling toward the host vehicle, and
the predetermined condition includes a condition that the oncoming vehicle is present.
6 . The vehicle stop position determination system according to claim 5 , wherein
the environmental sensor is further configured to detect a leading vehicle in front of the host vehicle, and
the predetermined condition further includes a condition that no leading vehicle is present.
7 . The vehicle stop position determination system according to claim 1 , wherein
the processor is configured to determine the optimal stop position for the road intersection by calculating an average of the stop positions stored in the computer memory.
8 . The vehicle stop position determination system according to claim 1 , wherein
the processor is configured to determine the optimal stop position for the road intersection by choosing one of the stop positions stored in the computer memory.
9 . The vehicle stop position determination system according to claim 1 , wherein
the computer memory is further configured to store a digital map, and
the processor is further configured to update the digital map stored in the computer memory by annotating the optimal stop position for the road intersection.
10 . The vehicle stop position determination system according to claim 1 , wherein
the computer memory is provided to the host vehicle, the computer memory being configured to store the traveling environment data and the driving status data associated with position data of the host vehicle.
11 . The vehicle stop position determination system according to claim 10 , further comprising
a remote processing system remotely provided relative to the host vehicle, the remote processing system including the processor, and
a wireless communicator provided to the host vehicle, the wireless communicator being configured to wirelessly transmit the traveling environment data and the driving status data associated with the position data of the host vehicle to the remote processing system.
12 . The vehicle stop position determination system according to claim 1 , wherein
the environmental sensor, the vehicle sensor and the processor are provided to the host vehicle.
13 . The vehicle stop position determination system according to claim 12 , further comprising
the computer memory is provided to the host vehicle.
14 . The vehicle stop position determination system according to claim 12 , further comprising
a remote processing system remotely provided relative to the host vehicle, the remote processing system including the computer memory.
15 . The vehicle stop position determination system according to claim 14 , further comprising
a wireless communicator provided to the host vehicle, the wireless communicator being configured to wirelessly transmit the stop position determined by the processor to the remote processing system.
16 . The vehicle stop position determination system according to claim 14 , wherein
the remote processing system further includes a processor that is configured to determine the optimal stop position for the road intersection based on the stop positions stored in the computer memory.
17 . A vehicle stop position determination method comprising:
detecting, by an environmental sensor, traveling environment of a host vehicle to collect traveling environment data;
detecting, by a vehicle sensor, driving status of the host vehicle to collect driving status data;
determining, by a processor, a position of the host vehicle at a timing when the driving status data indicates that the host vehicle is stopping and the traveling environment data indicates a predetermined condition based on a relative position of the host vehicle relative to a road intersection, as a stop position for the road intersection; and
storing, by a computer memory, stop positions for the road intersection to calculate an optimal stop position for the road intersection based on the stop positions stored in the computer memory, the stop positions being at least partially determined by the processor.
