Report Description

Steer-by-wire is no longer a technology for the future: Nissan Motor has put it in a full-production car, the Skyline hybrid. Nissan has positioned steer-by-wire as a strategic technology vital to global competitiveness, developing the software in-house, and offering improved reliability with full mechanical backup.

Unpleasant road impacts are eliminated, but the rack force from the wheels, essential for safe driving, is transmitted accurately to the driver through a resistance feedback motor. Nissan engineers developed a new technology to estimate rack force with high precision. Independent electrical and mechanical systems boost reliability with full redundancy, and three ECUs monitor the system and each other.
