In-vehicle electronic control unit for program verification

A vehicle control method comprising:

• executing a computation of first control software when a vehicle is in a first state and executing a computation of second control software when the vehicle is in a second state, wherein the first state comprises an autonomous driving state of the vehicle, and the second state comprises manual driving state;
• storing input data that is inputted from a sensor to the first control software and to the second control software, in a saving unit and storing output data that the first control software and the second control software output as a result of a computation executed with the input data as input, in the saving unit;
• and
• comparing pieces of the output data that is outputted respectively from the first control software and the second control software, the output data being read from the saving unit, to evaluate performance of the second control software.

A vehicle control system comprising at least one processor configured to:

• execute a computation of first control software when a vehicle is in a first state and a computation of second control software when a vehicle is in a second state, wherein the first state comprises an autonomous driving state of the vehicle, and the second state comprises manual driving state;
• saving input data from a sensor to the first control software and to the second control software, the saving unit saving output data that the first control software and the second control software output as a result of a computation executed with the input data as input to the computation;
• and
• comparing pieces of the output data outputted respectively from the first control software and the second control software, the output data being read from a storage unit, to evaluate performance of the second control software.
