Bosch Launches Drive-by-Wire Brake System for Cars

STUTTGART, Germany — German component company Bosch is launching a new drive-by-wire braking system which could be coming to a car near you this year.
The system cuts out the mechanical connection between the foot and the brake disc and does away with traditional hydraulic componentry.
The brake-by-wire braking system uses a remote-controlled actuator that presses the brake pads onto the rotating brake disc when activated.
Bosch said it was planning to market the system from the last quarter of this year.
The company also said it has already received orders from vehicle manufacturers and expects that by 2030, more than 5.5 million vehicles worldwide will be equipped with brake-by-wire.

Bosch said the system saves weight and installation space because there is no need for hydraulics, namely no hoses, reservoirs, brake cylinders and control units.
The news is good for electric cars, which rely on lightweight construction to increase range.
The brake-by-wire system is being developed at the Bosch development center near Heilbronn.
For safety reasons the cables, control units and actuators are duplicated in case of failure, said Bosch. It pointed to the reliability of brake-by-wire systems which have been fitted to commercial aircraft for some years.
Bosch said engineers have since tested the brake-by-wire system in a Nissan Leaf during a journey to the Arctic Circle that lasted six days and covered 3,300 kilometers on public roads.
