    • PURPOSE: A safety start system and a method of a vehicle are provided to prevent sudden start of a vehicle in advance by starting an engine only when a foot brake is operated and a gear is in a neutral position. CONSTITUTION: A safety start system of a vehicle is composed of an engine RPM(Revolution Per Minute) detecting unit for outputting RPM of an engine; a foot brake input detecting unit for sensing if a brake is operated; a gear position detecting unit for sensing if a gear is in a neutral position(N); a vehicle speed sensing unit operated with the foot brake input detecting unit in parallel to detect the speed of the vehicle; a vacuum unit(70) driven by operation power applied from a battery(80) to suck in the air in a hydro-bag when a key switch is in an ACC(Accessory) state; a control unit for starting the engine when the foot brake is operated and a gear is in a neutral position, preventing the gear from being shifted until RPM of the engine is decreased below a reference value after starting the engine, and turning off the vacuum unit when the engine rotates; a gear shift lever lock unit for fixing the gear in the neutral position according to the control unit if RPM of the engine is over the reference value; and a starter for starting the engine according to controls of the control unit.
    • 目的:提供一种安全起动系统和车辆的方法,以仅在脚踏制动器被操作并且齿轮处于中立位置时才通过启动发动机来预先突然启动车辆。 构成:车辆的安全起动系统由发动机的RPM的发动机转速(每分钟转数)检测单元构成, 脚制动器输入检测单元,用于检测制动器是否被操作; 齿轮位置检测单元,用于检测齿轮是否在中性位置(N); 与脚制动器输入检测单元并行地操作的车速检测单元,以检测车辆的速度; 当密钥开关处于ACC(附件)状态时,由从电池(80)施加的操作电力驱动以在水包中吸入空气的真空单元(70) 控制单元,用于在脚踏制动器被操作并且齿轮处于中间位置时起动发动机,防止齿轮在发动机的RPM降低到起动发动机之后的基准值以下,并且关闭真空单元 当发动机旋转时; 变速杆锁定单元,用于如果所述发动机的转速超过所述参考值,则根据所述控制单元将所述齿轮固定在所述中立位置; 以及用于根据控制单元的控制启动发动机的起动器。
