Mr. Sanchez asked why only R² is used for the HILS verification. He suggested that slope and intercept of the regression might need to be added.

JASIC indicated that the verification results of the Volvo bus looked very good for a first shot. The driver model might need to be adjusted after the first full verification to get better results with the second shot. It was also reported that the Japanese procedure has different R² values for parallel and serial hybrids.
