Description of the Invention: [Technical Field] The present invention relates to a control device for igniting and starting a locomotive engine, and more particularly to a control device suitable for waiting for a traffic light and a stop of a locomotive engine when a traffic light is stopped. [Prior Art] Due to the increasingly stringent requirements of environmental protection regulations, environmental protection related units in various countries have gradually requested that steam and locomotives wait for traffic lights, traffic jams, and roadside suspensions, that is, when idle speed exceeds a certain period of time (such as 3 minutes). The engine must be forced to go out. Therefore, how to control the engine to turn off at idle speed, suppress the gas emissions of steam and locomotives, and reduce the consumption of gasoline fuel is an urgent problem for vehicle manufacturers. The technology of using the locomotive to make the engine bonfire at idle speed mostly utilizes the original key switch on the vehicle, that is, the driver directly turns the start switch to the closed position (〇ff) by the key to control the engine. Fire, = and if the engine is to be started again after the flameout, the driver still needs to turn the start switch to the eight-open position (〇n). This operation mode is more complicated and time-consuming is not ideal. Some locomotives that have been listed for sale in recent years have used the electric motor of the squirting engine ^ ^ ^ lTZ°nic contro1 Unit: ^ ^ t to strike whether the fire should be smashed, the position of the scorpion = the position of the two doors to judge the engine fire. After the recording element is logically judged, the signal is sent out. The b-type method can accurately judge and help the driver to complete the 1374818 flameout action, but many sensors are required to measure a variety of different and necessary interpretation messages, so that zero The number of components has increased, the overall locomotive and for the driver, the electronic control unit to extinguish the engine is a sudden action, does not meet the intuitive will of the driver, is not very ideal, there is still room for improvement. In the spirit of active invention, a control device for igniting and starting the locomotive engine that can solve the above problems = after several research experiments to complete the present invention. SUMMARY OF THE INVENTION The present invention relates to a control device for igniting and starting a locomotive engine' which includes a gripper sensor, a vehicle speed sensor, and a control unit. The grip sensor is used to detect whether the handle of a locomotive is being held, the speed sensor is used to measure the speed of the locomotive, and the control unit is electrically connected to the grip sensor and the vehicle speed sensor. Wherein, when the locomotive engine is in the starting state, and the grip sensor detects that the handle of the locomotive is not being held, and the speed sensor detects that the speed of the locomotive is zero, the control unit outputs a signal to control the locomotive engine to stall. Therefore, in this embodiment, only one vehicle speed sensor is needed, and then the handle of the locomotive is configured to detect whether the driver's hand holds the handle of the locomotive, and the engine can be turned off. The slewing type of the conventional locomotive not only conforms to the driver's will, but also has a relatively simple strategy and actual operation, and does not need to install multiple sensors to detect the engine state, and can also effectively reduce the cost. 1374818 The invention may further include a timer electrically coupled to the control unit for measuring the duration of time the handle is not held. Another type of flameout method of the present invention is when the locomotive engine is in the starting state, and the gripper sensor detects that the handle of the locomotive is not gripped, the speed sensor detects that the speed of the locomotive is zero, and the timer measures When the duration of the handle is not held reaches a predetermined value, the control unit outputs a signal to control the locomotive engine to stall. The predetermined value of the duration in which the handle is not held can be set to a fixed time, for example, a fixed number of seconds between 5 and 1 second. • In addition, the grip sensor can be fixed to the throttle handle of the locomotive or the other handle of the locomotive. It can detect whether the handle of the locomotive has the function of breaking the driver's hand. Alternatively, the grip sensor can be a photoreceptor sensor 'near sensor, electromagnetic sensor, or other equivalent function perceptron. Furthermore, the present invention may further comprise a throttle sensor for measuring the throttle opening of the locomotive engine, and a starter motor for starting the locomotive engine, the throttle sensor and the starter motor and electrically connected to the control unit. Wherein, when the φ car engine is in the flameout state, the gripper sensor detects that the handle is held' and the throttle sensor measures the throttle opening of the locomotive engine to be non-zero, the control unit outputs a signal to control the start. The motor runs and its speed reaches the threshold of the starter engine for the engine of the engine. That is, when the locomotive is in an idle state and the engine is turned off, the present invention can also use the detection signals of the grip sensor and the throttle sensor to control the start of the motor and then start the engine, thereby simplifying the engine to bonfire under rapid conditions. After starting the program. 1374818. Moreover, when the locomotive engine has been restarted, the control unit can output a signal to control the starter motor to stop running, to prevent the engine from being started, and the starter motor continues to operate. In addition, the above control unit can be integrated into the original electronic control unit (ECU) of the locomotive, which can save the number of parts and reduce the cost. [Embodiment] Please refer to FIG. 2 and FIG. 2, which are respectively the first The engine bonfire system architecture diagram and the flowchart of the preferred embodiment, the embodiment is a control device for the engine f engine flameout. The system architecture includes: a grip sensing benefit 20, a vehicle speed sensor 22, and - Control unit %. The residual sensor μ is used for the locomotive - whether the handle is held, the vehicle speed sensor 22 is used to measure the speed of the locomotive, the control unit is electrically connected to the grip sensor 20 and the vehicle speed Perceptron 22. As shown in Fig. 2, when the locomotive engine 15 is in the starting state, the gripper sensor 2 detects that the handle is not gripped, and the vehicle speed sensor 22 measures the speed of the locomotive to zero, the control unit 3_Output-signal to control the locomotive engine bonfire. In this embodiment, the gripper sensor 2() is a photoresistor sensor, and the gripper sensor 2 is fixed to the throttle handle of the locomotive. This embodiment only needs one car The sensor 22 uses the grip sensor 2 disposed on the throttle handle of the locomotive to detect whether the driver's hand grips the throttle handle of the locomotive. The locomotive engine 15 can be turned off. This type of flameout is not only better than the conventional locomotive. The flameout method is in line with the will of the driver. The 1374818 strategy and actual operation are relatively simple, and - m. Not only the women's eve sensor to detect the state of the w, but also effectively reduce the cost.
