The invention discloses an automobile emergency braking device and method and a braking pipeline pressure buildup method. The device comprises a vehicle danger induction detection device, a vehicle controller and a brake mechanism. After the vehicle controller judges that the vehicle meets an emergency braking condition according to detection data sent by the vehicle danger induction detection device, the brake mechanism is controlled to actively perform emergency brake action; the brake mechanism comprises an active brake control mechanism, a manual brake control mechanism, a brake device connected with the active brake control mechanism and the manual brake control mechanism through pipelines, and a manual brake failure relief mechanism arranged on a pipeline connecting path between a brake oil cylinder and the brake device. And after manual braking fails, the vehicle controller controls and starts the manual braking failure relief mechanism to communicate a connecting pipeline between the braking oil cylinder and the brake device, hydraulic oil in the brake oil cylinder is conveyed to the brake device, and relief braking is achieved. According to the invention, the effectivenessof emergency braking and the driving safety are improved.
