Description of the Invention: [Technical Field] The present invention relates to a finger-to-hand control method and apparatus for a locomotive bow, and particularly to a method and apparatus thereof. Evil 'control 51 engine automatic bonfire, and restarted [previous technology] In today's society, locomotives because of their favorite short-distance traffic u 4W and speed, it is environmentally conscious, such as the domain in recent years, can be secret Lack of issues and vehicle development goals. The section of the Department of Vacancy Reduction has become the structure diagram of the 心 嚟 「 德 德 德 德 德 德 德 CN CN CN CN CN CN CN CN CN CN CN CN CN CN CN CN CN CN CN CN When running, open the door and restart the bow engine. "Turn off the flames of the bow" and pass the sensing throttle in which the 'Chinese patented relatives ^ & engine engine idle speed control i ^ CNl815G12A exposed "machine switch 102, air load switch 103 (or two closed ignition switch 10 brake 105 The starter relay 10 = switch 1G4) and the electric start switch machine 107 drive the engine to rotate. The battery (10) is energized and activated. When the engine is running, the ten-a son control unit 108 senses the throttle click to determine whether the locomotive stops. Idle speed a, η opening degree, the detector 1〇9 will transmit the closed field> When the door opening degree returns to the bottom, the sensing unit (10) will be in the sensing unit control unit 108, electronic control " °. 109 closing time When the set time is exceeded, the command of 200909674 causes the engine trigger coil 110 to be shorted or opened to stop the engine. During the engine stop, when the throttle opening is slightly rotated, the sensor 109 will transmit to the electronic control unit 108. The signal, the electronic control unit 108 further determines whether the engine flameout time does not exceed the preset engine flameout time. If the preset engine flameout time is not exceeded, an instruction is made to enable the relay to start. When the contact of 106 is closed, the starter motor 107 is energized to drive the engine to operate. The "automobile engine idle speed control device" disclosed in the Chinese Patent Publication No. CN1815012A uses the throttle opening degree to be zero, and determines that the locomotive is idle and idle. And stop the engine. However, when the car goes downhill or walks into the room, the throttle of the hand will also be zeroed, which may cause the vehicle to stop running at an idle speed, causing the engine to stop running, causing danger on the road. Moreover, the control engine is stopped, and the electronic control unit 108 is required to make an instruction to control the engine to trigger the short circuit or open circuit of the coil 110, which is easy to cause time and cost. In addition, it does not consider that the battery 100 needs to be started up frequently during the idle operation, which may cause the power to drop, resulting in the engine being unable to start, which is inconvenient and dangerous.
