Beschreibung
Zusammenfassung:	The invention relates to the technical field of electronic hydraulic braking, in particular to a forward collision prevention method and system based on electronic hydraulic braking. The method includes the steps that an environment perception unit acquires and outputs environment information to a danger judgment unit; the danger judgment unit computes the pre-collision time t and judges and sends the danger level of collision to an electronic control unit; the electronic control unit sends an alarm and/or brake command to an execution unit according to the different danger levels; and the execution unit conducts alarming and/or braking according to the command. Based on an electronic hydraulic braking system, the response speed is high. According to the different danger levels, a danger alarm is given to a driver; and when the danger level is high or extremely high, a horn system can be controlled to give pedestrians a prompt that the danger exists, so that the safety of the pedestrians around vehicles is guaranteed.
