Major suppliers and customers of brake-by-wire systems

The brake-by-wire system is mainly provided by Bosch, Continental, ZF and other parts companies. EHB technology is relatively mature abroad, but it is still not suitable for L4 autonomous driving. EMB is in the research stage and it is difficult to make a breakthrough. Bosch's iBooster is a typical direct EHB, used in conjunction with ESP. Bosch has also launched the IPB+RBU brake-by-wire system for L3 and L4.
