Abstract

An upper-limit speed of a vehicle in automatic parking control is set, and the vehicle is caused to park automatically in a parking space at a vehicle speed equal to or lower than the set upper-limit speed. In this case, the upper-limit speed is set according to a vehicle body size of the vehicle, and the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size.

Claims (31)

1. An automatic parking system comprising: a sensor configured to detect circumstances around a vehicle, and a processor configured to set an upper-limit speed of the vehicle in the automatic parking control, wherein the processor is configured to:

set the upper-limit speed according to a vehicle body size of the vehicle such that the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size,

determine a degree of contact risk of the vehicle with an object other than the vehicle based on the circumstances of the vehicle detected by the sensor,

set the upper-limit speed according to the vehicle body size of the vehicle when it is determined that the degree of contact risk is greater than a preset degree threshold,

set the upper-limit speed according to the vehicle body size of the vehicle and the degree of contact risk such that the upper-limit speed is lower when it is determined that the degree of contact risk is greater than the preset degree threshold than when it is determined that the degree of contact risk is not greater than the preset degree threshold,

set the upper-limit speed according to the vehicle body size of the vehicle when it is determined that the degree of contact risk is greater than the preset degree threshold such that the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size; and

perform automatic parking control for automatically parking the vehicle in a parking space at a vehicle speed which is equal to or lower than the upper-limit speed set by the processor.

2. The automatic parking system according to claim 1 , wherein the processor is configured to determine that the contact risk degree is greater than the first threshold in a case where the sensor detects a congestion degree around the vehicle based on the circumstances around the vehicle detected by the sensor and the congestion degree is greater than a second threshold.

3. The automatic parking system according to claim 1 , wherein: the sensor is a camera configured to capture the circumstances around the vehicle; and

the processor is configured to

analyze whether the captured circumstances around the vehicle include a presence of a child, and

determine that the contact risk degree is greater than the first threshold in a case where the child is present around the vehicle based on a result of analyzing the captured circumstances around the vehicle.

4. The automatic parking system according to claim 1 , wherein the processor is configured to determine that the contact risk degree is greater than the first threshold in a case where the sensor detects a vehicle size of another vehicle around the vehicle based on the circumstances around the vehicle detected by the sensor and the vehicle size of the other vehicle is greater than a second preset size.

5. The automatic parking system according to claim 1 , wherein the processor is configured to determine that the contact risk degree is greater than the first threshold in a case where the processor determines whether a blind spot which is unable to be detected by the sensor is present around the vehicle based on the circumstances around the vehicle detected by the sensor and the blind spot is present around the vehicle.

6. The automatic parking system according to claim 1 , wherein the processor is configured to determine that the contact risk degree is greater than the first threshold in a case where the sensor detects a crosswalk around the vehicle based on the circumstances around the vehicle detected by the sensor and the crosswalk is present around the vehicle.

7. The automatic parking system according to claim 1 , wherein the processor is configured to determine that the contact risk degree is greater than the first threshold in a case where weather around the vehicle is acquired based on the circumstances around the vehicle detected by the sensor and weather around the vehicle is preset bad weather.

8. The automatic parking system according to claim 1 , wherein the sensor is at least one of a camera, a LIDAR, and a radar.

9. An automatic parking method comprising: detecting circumstances around a vehicle; and setting an upper-limit speed of the vehicle in automatic parking control, wherein the setting of the upper-limit speed includes:

setting the upper-limit speed according to a vehicle body size of the vehicle such that the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size,

determining a degree of contact risk of the vehicle with an object other than the vehicle based on the circumstances of the vehicle detected by the sensor,

setting the upper-limit speed according to the vehicle body size of the vehicle when it is determined that the degree of contact risk is greater than a preset degree threshold,

setting the upper-limit speed according to the vehicle body size of the vehicle and the degree of contact risk such that the upper-limit speed is lower when it is determined that the degree of contact risk is greater than the preset degree threshold than when it is determined that the degree of contact risk is not greater than the preset degree threshold,

setting the upper-limit speed according to the vehicle body size of the vehicle when it is determined that the degree of contact risk is greater than the preset degree threshold such that the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size; and

performing automatic parking control for automatically parking the vehicle in a parking space at a vehicle speed which is equal to or lower than the upper-limit speed.

10. A non-transitory storage medium storing instructions cause a computer to perform: detecting circumstances around a vehicle; and setting an upper-limit speed of the vehicle in automatic parking control, wherein the setting of the upper-limit speed includes:

setting the upper-limit speed according to a vehicle body size of the vehicle such that the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size,

determining a degree of contact risk of the vehicle with an object other than the vehicle based on the circumstances of the vehicle detected by the sensor,

setting the upper-limit speed according to the vehicle body size of the vehicle when it is determined that the degree of contact risk is greater than a preset degree threshold,

setting the upper-limit speed according to the vehicle body size of the vehicle and the degree of contact risk such that the upper-limit speed is lower when it is determined that the degree of contact risk is greater than the preset degree threshold than when it is determined that the degree of contact risk is not greater than the preset degree threshold,

setting the upper-limit speed according to the vehicle body size of the vehicle when it is determined that the degree of contact risk is greater than the preset degree threshold such that the upper-limit speed is lower when the vehicle body size of the vehicle is greater than a preset size than when the vehicle body size of the vehicle is less than the preset size; and

performing automatic parking control for automatically parking the vehicle in a parking space at a vehicle speed which is equal to or lower than the upper-limit speed.
