Nissan Unveils Lunar Rover Prototype

Nissan unveiled a lunar rover prototype jointly developed with the Japan Aerospace Exploration Agency (JAXA). The JAXA Space Exploration Innovation Hub Center is conducting research on lunar rovers for space exploration. Nissan has been working with JAXA on driving the controllability of the rovers since January 2020.

A lunar rover must be able to traverse the Moon’s powdery, rocky and undulating terrain and be energy efficient. Furthermore, energy sources for operating vehicles in space are limited. Nissan’s research applies the motor control technology it has developed through its production of mass-market electric vehicles such as the LEAF as well as the e-4ORCE all-wheel control technology featured on the all-new Ariya electric crossover. In particular, it is e-4ORCE that is boosting the lunar rover’s performance over tricky terrain.

Nissan has focused on the development of stable driving performance that enables customers to drive their cars with greater confidence. Nissan’s e-4ORCE technology precisely controls all four wheels independently, providing the driver with confidence in various conditions.

In its joint research with JAXA, Nissan is evolving e-4ORCE technology to improve its performance in sandy terrain and other harsh conditions. When cars are driven in sand their wheels frequently spin and dig in, impeding progress. A high level of driving skill is required to avoid getting stuck. To meet this need, Nissan has developed driving-force controls that minimize the amount of wheel spin in accordance with surface conditions.

Through the joint research, 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
