Electronically controlled brake (ECB) developed by Toyota Motor Corporation initially for its hybrid and Lexus models, is the world's first production brake-by-wire braking system. The ECB went on sale in Japan in June 2001, first appearing on the Toyota Estima hybrid (first generation), and making its North American debut with the launch of the Lexus RX 400h SUV in April 2005. The ECB is an integral part of the company's Vehicle Dynamics Integrated Management stability control system, by allowing for automatic brake adjustments, which work in conjunction with variable gear-ratio electric power steering systems.
