1 System Description

Electro-mechanical brake (EMB) is a new type of braking technology aimed at electrification and intelligence of automobiles. Compared with the current mainstream electronic hydraulic brake (EHB), EMB achieves a 'dry' braking method which innovates in structure by eliminating brake fluid, hydraulic pipelines, vacuum boosters, and other related parts. The advantages include reducing vehicle weight, saving subsequent maintenance, and freeing up chassis space. Moreover, the response time is 80 to 100 milliseconds, which is about twice as fast as an EHB, and significantly shortens braking distance. The motor directly controls the EMB, providing more precise operation, which is also beneficial for the precise control required in advanced autonomous driving. This reference design shows a EMB design. The hardware, software and functional safety design are all illustrated in this guide.
