Map information system

A driver assist control method comprising:

• acquiring, based on driving environment information indicating a driving environment of a vehicle, with an intention of a driver to intervene in a driver assistance control when a phenomenon undesirable for the driver assistance control is present, intervention operation information indicating an intervention operation location that is a location where an intervention operation is performed, the intervention operation being an operation performed by the driver of the vehicle to intervene in driving assist control during execution of the driving assist control, the driving environment information including information indicating that the intervention operation has been performed,
• acquiring, based on a map information, an evaluation value for each point or section within a target range, the map information being used for driving assist control for assisting driving of the vehicle and being associated with the evaluation value indicating a certainty of the map information for each location in an absolute coordinate system,
• determining, based on the evaluation value and the intervention operation location, an allowable level of the driving assist control that is allowed when the vehicle travels in the target range for each point or section within the target range, and
• performing the driving assist control of the allowable level of the driving assist control, based on the driving environment information and the map information, wherein
• when a combination of a plurality of types of map information is used for the driving assist control, the evaluation value of each of the plurality of types of map information is used to obtain two or more allowable levels for a same point or section within the target range, and the two or more allowable levels are combined to determine a final allowable level of the driving assist control,
• the determining of the allowable level of the driving assist control includes setting the allowable level of the driving assist control to be equal to or less than the allowable level of the driving assist control in a normal location that is not the intervention operation location, on condition that the evaluation values in the intervention operation location and the normal location are identical, and
• the method further comprising:
• maintaining the evaluation value in a normal position while reducing the evaluation value in the intervention operation location to acquire a corrected evaluation value,
• setting the allowable level of the driving assist control to a first level in a location where the corrected evaluation value is less than a threshold, and
• setting the allowable level of the driving assist control to a second level that is higher than the first level in a location where the corrected evaluation value is equal to or more than the threshold.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
• acquire, based on driving environment information indicating a driving environment of a vehicle, with an intention of a driver to intervene in a driver assistance control when a phenomenon undesirable for the driver assistance control is present, intervention operation information indicating an intervention operation location that is a location where an intervention operation is performed, the intervention operation being an operation performed by the driver of the vehicle to intervene in driving assist control during execution of the driving assist control, the driving environment information including information indicating that the intervention operation has been performed,
• acquire, based on a map information, an evaluation value for each point or section within a target range, the map information being used for driving assist control for assisting driving of the vehicle and being associated with the evaluation value indicating a certainty of the map information for each location in an absolute coordinate system,
• determine, based on the evaluation value and the intervention operation location, an allowable level of the driving assist control that is allowed when the vehicle travels in the target range for each point or section within the target range, and
• perform the driving assist control of the allowable level of the driving assist control, based on the driving environment information and the map information, wherein
• when a combination of a plurality of types of map information is used for the driving assist control, the evaluation value of each of the plurality of types of map information is used to obtain two or more allowable levels for a same point or section within the target range, and the two or more allowable levels are combined to determine a final allowable level of the driving assist control,
• the instructions, when executed by the one or more processors of the device, further cause the one or more processors to set the allowable level of the driving assist control to be equal to or less than the allowable level of the driving assist control in a normal location that is not the intervention operation location, on condition that the evaluation values in the intervention operation location and the normal location are identical, and
• the instructions, when executed by the one or more processors of the device, further cause the one or more processors to:
• maintain the evaluation value in a normal position while reducing the evaluation value in the intervention operation location to acquire a corrected evaluation value,
• set the allowable level of the driving assist control to a first level in a location where the corrected evaluation value is less than a threshold, and
• set the allowable level of the driving assist control to a second level that is higher than the first level in a location where the corrected evaluation value is equal to or more than the threshold.
