> Toyota fixed the major problem with Tesla’s wheel by introducing its “wing-shaped” steering wheel with a steer-by-wire system enabling what Toyota calls a “one motion grip”: Lock-to-lock is set at around 150 degrees.
I’ve always assumed most cars have mechanical steering with power assistance, so they’ll work in the event of a power failure. But a Lock to lock of 150 degrees sounds like it would be impossible to move even if there is a mechanical connection from steering to wheels.
- xnyan 5y agoMost manufacturers have already moved from hydraulic to electric motor steering systems, and steer-by-wire is the next step. It's not very common today, but the pace is picking up because the advantages (far fewer mechanical parts, automation) are tempting. Reliability is going to come down to implementation. In some cases you actually have advantages in control-by-wire (less mechanical parts to fail). You can also implement mechanical overrides for emergency situations.
