Siemens VDO announces brake-by-wire system

Electronically-controlled mechanical brake systems developed by eStop, a company acquired by Siemens VDO Automotive earlier this year, look poised to replace traditional hydraulic brake systems for many applications.
In this system, each wheel is independently controlled by an intelligent braking module, combining a 12-volt electrically actuated "wedge brake" mechanical system and electronic sensors monitoring movement and force.

Eliminating the hydraulic system of pipes, brake cylinders, brake boosters and antilock control units lowers vehicle weight, increases reliability, and reduces maintenance requirements. In addition, the system eliminates the need for a separate parking brake. Overall, the system should open up some new packaging opportunities for the car designer.

Siemens expects the system to see production in this decade.
