Japanese automakers, map-making companies, and the government will get together to generate standardised intelligent maps, with plans to incorporate driving data gathered by the automakers, the paper said on Sunday.

A Toyota spokesman declined to comment, while officials at Nissan could not be reached immediately for comment.

Intelligent mapping systems supply information to control self-driving cars, which are equipped with street-scanning sensors to measure traffic and road conditions.

German auto supplier Bosch said on Friday it was in talks with high-definition digital maps company HERE, exploring whether to take a stake.

Volkswagen's Audi, Daimler's Mercedes-Benz, BMW and car parts supplier Continental are also working on technologies for autonomous or semi-autonomous cars.
