The Japan Aerospace Exploration Agency (JAXA) in collaboration with Nissan Motor Co., Ltd. unveiled a lunar rover prototype at its Nissan Futures Event.

FREMONT, CA: Nissan Motor Co., Ltd., in association with the Japan Aerospace Exploration Agency (JAXA) unveiled a lunar rover prototype at the Nissan Futures Event. Lunar rovers are a key technology for space exploration, it navigates the Moon's powdery, stony, and undulating environment while conserving energy.

Nissan uses the motor control technology that it has developed during mass-market electric vehicle production such as the LEAF, as well as the e-4ORCE all-wheel control technology found on the all-new Ariya electric crossover.

Through the joint research with JAXA, Nissan aims to contribute to the technological evolution of automotive technology and space exploration technology by sharing know-how gained from test-vehicle development and combining it with JAXA's knowledge of rover research. Nissan has concentrated on the creation of a reliable driving performance that would allow consumers to drive with more confidence in their vehicles.

To produce traction during acceleration, each motor's torque in the Nissan Ariya e-4ORCE variant can be adjusted separately. The amount of regeneration for the front and rear motors is individually regulated when decelerating. e-4ORCE reduces dip and body tremor during braking. The torque of the front and rear motors, as well as the braking performance of all four wheels, are controlled around curves to provide smooth and pleasant handling. Drivers of all skill levels can confidently negotiate diverse road conditions, including rain and snow, with these settings.

The JAXA Space Exploration Innovation Hub Center aims to incorporate the research results into future space exploration. They have plans on collaborating with companies, universities, and research institutes on projects that are feasible and have the potential for commercialization and innovation. Moreover, they are looking forward to researching with Nissan to apply their findings to the development of higher-performance lunar covers. While Nissan aims for the ultimate driving performance to their customers through joint research and development along with JAXA.
