The invention discloses an automobile emergency braking device and a braking method. The automobile emergency braking device comprises an automobile danger induction detection device, an automobile controller and a braking mechanism. After the vehicle controller judges that the vehicle meets the emergency braking condition according to the 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 braking device. After manual braking fails, the automobile controller controls and starts the manual braking failure relief mechanism to communicate a connecting pipeline between the brake oil cylinder and the braking device, hydraulic oil in the brake oil cylinder is conveyed to the brake device, and the relief braking is achieved. According to the invention, the effectiveness of emergency braking is improved, and the driving safety is further improved.
