Abstract
A battery electric vehicle that uses an electric motor as a traction power unit includes one or more speakers that output sound to at least one of inside and outside of the vehicle, one or more processors, and one or more storage devices for storing usage state information of the electric vehicle and sound source data. The one or more processors estimate fitness of the battery electric vehicle based on the usage state information. The one or more processors generate, based on the sound source data, a sound in accordance with the fitness. The one or more processors are configured to output the generated sound through the one or more speakers.
Claims11
A battery electric vehicle that uses an electric motor as a traction power unit, the battery electric vehicle comprising:
- one or more speakers that output sound to at least one of inside and outside of the vehicle;
- one or more processors;
- and
- one or more storage devices for storing usage state information of the battery electric vehicle and sound source data, wherein the usage state information includes types of information that serve as indicators of whether the battery electric vehicle is being used appropriately, and wherein the one or more processors are configured to
- estimate a fitness of the battery electric vehicle based on the usage state information, wherein the fitness of the battery electric vehicle means a degree indicating how good a condition of the vehicle is,
- generate, based on the sound source data, sound that varies as a function of the fitness, wherein the generated sound includes at least one of an increase in pressure of the sound, an increase in frequency of the sound, or a selection of sound source data with a brighter tone, corresponding to a higher fitness of the battery electric vehicle, and
- output the generated sound through the one or more speakers.
