X-by-wire technology

This paper reviews some new remote control and computer-linked systems that may increase safety. A new development is the replacement of mechanical links between the driver and the road wheels with electrical wires. This may apply to one or more of the primary systems such as brakes, steering and throttle. The remote control network, generically termed X-by-Wire will be routed through an on-board computer, allowing control systems to manipulate driver inputs. This has implications for safety. A combination of X-by-Wire systems may facilitate quicker reaction times, especially for evasive action and stabilising cars. When driver monitoring systems and lane keeping technology matures, computers may be able to assess the roadworthiness of the driver and act accordingly. While theoretically sound, reliability coupled with a loss of driver involvement is a concern.
