Nissan Debuts ‘Canto’ EV artificial engine sound technology at 2017 Tokyo Motor Show

Nissan used the Tokyo Motor Show as the venue to debut its “Canto” sound technology for EVs. Most modern EVs produce no sound and artificial sound is needed to warn pedestrians and other motorists about the approach of an oncoming EV.

Nissan has opted to use a melodious sound called “Canto” (which is derived from Latin and Spanish for “I sing”) in order to lend sound to the engine. As the car accelerates and decelerates, the “Canto” concept changes tone and pitch, just like a typical combustion car would. The sound begins as a continuous beeping noise, rises to a harmonious crescendo and then comes to an end.

The sound is activated at speeds of around 12 to 19 mph and is not loud enough to cause disturbance to the occupants or others on the road but is loud enough to attract the attention of pedestrians who might be passing by.

“An important element of Nissan Intelligent Mobility is how the vehicle integrates with society, and a crucial component of that is sound,” said Daniele Schillaci, Executive Vice President, Global Sales & Marketing.

He added that “‘Canto’ was developed to help with pedestrian safety, and is meant to represent a distinct Nissan sound in the electrified marketplace.

“Canto” is not the first attempt that Nissan has made to make its EV’s more audible. In 2010, Nissan had developed an “Approaching Vehicle Sound for Pedestrians” system for the first Leaf. That sound was rather bland. The Canto is more musical and makes an EV sound a lot cooler while at the same time contributing significantly to the safety of pedestrians.
