BYD Denza Z steer-by-wire

5 hours ago

BYD's Denza Z electric sports car features a proprietary steer-by-wire system replacing the traditional mechanical steering column.
The system uses a FinDreams POR8 single-winding motor on the front axle and two independent rear steering motors, enabling a triple-motor setup for improved maneuverability.
Steer-by-wire operates with 0.1° precision and faster response times, reducing the turning radius to 4.62 meters.
Safety includes a six-layer redundancy architecture with dual chips, independent power circuits, and multiple fail-safes integrated with the E³ platform.
The technology targets luxury performance vehicles and debuted alongside new Chinese regulatory standards for steer-by-wire systems.
BYD's domestic EV sales showed strong growth from February to May, reaching 15,620 units in May with a 1.0% market share.
