Method for checking a digital map of an environment of a motor vehicle

A method for checking a digital map of an environment of a motor vehicle, comprising the following steps:

• receiving the digital map transmitted from the motor vehicle via a communication network using an out-of-vehicle checking system;
• checking the received digital map based on a digital reference map using the checking system to ascertain an out-of-vehicle check result;
• and
• transmitting the out-of-vehicle check result using the checking system, to the motor vehicle via the communication network.

A device configured to check a digital map of an environment of a motor vehicle, the device configured to:

• transmit the digital map by the motor vehicle to an out-of-vehicle checking system via a communication network to check the digital map using the checking system;
• receive, by the motor vehicle, an out-of-vehicle check result of the digital map from the checking system via the communication network;
• check the digital map by the motor vehicle based on environment sensor data representing the environment of the motor vehicle from an environment sensor system of the motor vehicle to ascertain an in-vehicle check result;
• compare the out-of-vehicle check result with the in-vehicle check result to ascertain a comparison result;
• and
• ascertain at least one action to be carried out by the motor vehicle based on the comparison result.

A checking system configured to check a digital map of an environment of a motor vehicle, the checking system being an out-of-vehicle checking system, the out-of-vehicle checking system configured to:

• receive the digital map transmitted from the motor vehicle via a communication network using an out-of-vehicle checking system;
• check the received digital map based on a digital reference map using the checking system to ascertain an out-of-vehicle check result;
• and
• transmit the out-of-vehicle check result using the checking system, to the motor vehicle via the communication network.

A non-transitory machine-readable storage medium on which is stored a computer program for checking a digital map of an environment of a motor vehicle, the computer program, when executed by a computer, causing the computer to perform the following steps:

• transmitting the digital map by the motor vehicle to an out-of-vehicle checking system via a communication network to check the digital map using the checking system;
• receiving, by the motor vehicle, an out-of-vehicle check result of the digital map from the checking system via the communication network;
• checking the digital map by the motor vehicle based on environment sensor data representing the environment of the motor vehicle from an environment sensor system of the motor vehicle to ascertain an in-vehicle check result;
• comparing the out-of-vehicle check result with the in-vehicle check result to ascertain a comparison result;
• and
• ascertaining at least one action to be carried out by the motor vehicle based on the comparison result.
