Rebooting device when engine starts off by clutch operation error

摘要

This study is about the starting device of the car. More specifically, when the driver turns off the engine due to the clutch operation error, he does not use the "ign key", but uses the clutch pedal to start the restart device directly.;When the engine rpm is lower than 25 rpm, in order to dynamically stop the fuel pump drive circuit, the transistor is stopped, Therefore, due to the short circuit of the transistor mentioned above, the third relay will not be driven and the third switch will be turned to on.;In addition, due to stepping on the brake pedal, the second relay drive, the second switch is turned to on, and the parking brake is not used. Therefore, the first switch will continue to be in the on state.;And the last switch.When the second switch and the third switch are on at the same time, the power supply from the battery to the fourth relay is recognized, and the fourth switch is switched to on,Since the fourth switch mentioned above is coming, the power supply from the battery is recognized as the starting relay switch through the binary key terminal,Therefore, if you step on the clutch pedal, the clutch pedal switch will automatically switch on and off, and switch the engine relay switch to on, thus driving the start motor.It can be seen from the above description that when the engine is switched off during driving on a slope, only pressing the clutch pedal and restarting immediately can not only prevent accidents, but also drive safely.
