Citroen shows drive-by-wire C5

The absence of the pedal assembly and steering column considerably enhances safety, since the risk of injury in the event of impact is significantly reduced. In addition, the space freed up for the legs improves ergonomics and postural comfort.

Also, having the controls on the steering wheel increases the speed of execution, particularly when braking. Precious time is gained, since the driver no longer has to reach for the brake pedal.

Variable-ratio electric steering

The all-electric steering system provides a variable steering wheel angle/wheel angle ratio, adjusted automatically to suit the driver's requirements and the speed of the vehicle. In particular, this function makes parking much easier, thanks to the more direct steering ratio (between one and two turns of the wheel compared with three turns in normal cars). This feature also ensures pin-sharp steering at high speeds.

Ò Considerable latitude in adapting and defining steering parameters in terms of torque (controlling wheel vibration, for example), angle (small turns of the wheels) and vehicle behaviour (overall chassis control).

" Electro-hydraulic braking system

The braking system is electro-hydraulic. There is no pedal assembly, but the electric button on the steering wheel plays exactly the same role as a conventional system. Brake force is applied progressively, in an intuitive and natural way. To brake, the driver simply applies pressure to one or both of the steering wheel handles.

With the "C5 by Wire", Citroën is exploring new technological options. By eliminating mechanical limits and constraints, it aims to pioneer more attractive and ergonomic cockpit design that adapts to the needs of each driver and brings significant progress in active safety.
