Abstract
A computer system of a vehicle has processing circuitry to send a verification request message to an electrical energy storage system of the vehicle, receive a response message from the electrical energy storage system that depends on the existence of a correct digital key in a memory of the electrical energy storage system; when the digital key is correctly verified, allow electrical systems of the vehicle to use the electrical energy storage system, when the digital key cannot be correctly verified, limit the use of the electrical energy storage system for the electrical systems of the vehicle.
Claims16
A computer system of a vehicle comprising processing circuitry configured to:
- send a verification request message to an electrical energy storage system of the vehicle,
- receive a response message from the electrical energy storage system that depends on the existence of a correct digital key in a memory of the electrical energy storage system;
- when the digital key is correctly verified, allow electrical systems of the vehicle to use the electrical energy storage system,
- when the digital key cannot be correctly verified, limit the use of the electrical energy storage system for the electrical systems of the vehicle, wherein the electrical energy storage system includes a software reset function stored in the memory or accessible as a download file, the software reset function is configured to, upon being called, delete the digital key and a software access protection module from the memory.
A computer system of an electrical energy storage system comprising processing circuitry configured to:
- store, in a memory of the electrical energy storage system, a vehicle digital key verifiable by a vehicle processing circuitry, a software access protection module configured to protect unauthorized access to the memory, and a software reset function,
- receive a verification request message from the vehicle processing circuitry,
- send a response message to the vehicle processing circuitry, that:
- when the vehicle digital key is correctly verified, allows electrical systems of the vehicle to use the electrical energy storage system,
- when the vehicle digital key cannot be correctly verified, limits the use of the electrical energy storage system for the electrical systems of the vehicle,
- receive a software reset signal that calls the software reset function, and in response, delete at least the vehicle digital key from the memory.
A computer-implemented method, comprising:
- sending, by a processing circuitry of a computer system, a verification request message to an electrical energy storage system of the vehicle,
- receiving, by the processing circuitry, a response message from the electrical energy storage system that depends on the existence of a correct digital key in a memory of the electrical energy storage system;
- when the digital key is correctly verified, allowing, by the processing circuitry, electrical systems of the vehicle to use the electrical energy storage system,
- when the digital key cannot be correctly verified, limiting, by the processing circuitry, the use of the electrical energy storage system for the electrical systems of the vehicle, wherein the electrical energy storage system includes a software reset function stored in the memory or accessible as a download file, the software reset function is configured to, upon being called, delete the digital key and a software access protection module from the memory.
A computer-implemented method comprising:
- storing, by a processing circuitry of a computer system, in a memory of the electrical energy storage system, a vehicle digital key verifiable by a vehicle processing circuitry, a software access protection module configured to protect unauthorized access to the memory, and a software reset function,
- receiving, by the processing circuitry, a verification request message from the vehicle processing circuitry,
- sending, by the processing circuitry, a response message to the vehicle processing circuitry, that:
- when the vehicle digital key is correctly verified, allows electrical systems of the vehicle to use the electrical energy storage system,
- when the vehicle digital key cannot be correctly verified, limits the use of the electrical energy storage system for the electrical systems of the vehicle, and
- receiving, by the processing circuitry, a software reset signal that calls the software reset function, and in response,
- deleting, by the processing circuitry, at least the vehicle digital key from the memory.
