It belongs to the technical field

The present invention relates to a system for timely starting an engine, which is simpler to operate than a conventional engine.

Second, background Art

At present, automobile engines are known, and the starting of the engines is usually performed by manually turning an ignition switch or by pressing an engine start switch alone. These operating drawbacks are mainly the inconvenience of starting operations on vehicles equipped with automatic transmissions, equipped with idling-free driving devices and with engines that are often started.

Third, the invention

In order to enable a timely start of an engine mounted on a vehicle equipped with an automatic transmission, the present invention provides an engine timely start system that automatically starts the engine timely when a driver's demand for power is sensed.

The technical scheme adopted by the invention is as follows: the system is composed of a solid-state relay SSR1, a solid-state relay SSR2, an accelerator pedal switch K, a resistor R1, a diode D1, a diode D2 and a diode D3. In the starting timely starting system, one end of a resistor R1 is connected with an ON terminal of an ignition switch, and the other end of a resistor R1 is connected with the anode of a diode D2, the anode of a diode D3 and the positive terminal of an output circuit of a solid-state relay SSR 2; one end of an accelerator pedal switch K is grounded, and the other end of the accelerator pedal switch K is connected with the cathode of a diode D3; the positive pole of the diode D1 is connected with the negative pole of the diode D2, the negative pole of the diode D1 is connected with the positive terminal of the input circuit of the solid-state relay SSR1, the negative terminal of the input circuit of the solid-state relay SSR1 is grounded, the positive terminal of the output circuit of the solid-state relay SSR1 is connected with the positive pole of a starting power supply, and the negative terminal of the output circuit of the solid-state relay SSR1 is connected with the ST terminal of an ignition switch; the negative terminal of the output circuit of the solid-state relay SSR2 is grounded, the positive terminal of the input circuit of the solid-state relay SSR2 is connected with the L terminal, and the negative terminal of the input circuit of the solid-state relay SSR2 is grounded. The system utilizes an ignition switch signal, an accelerator pedal operation signal and a generator power generation signal, can automatically start the engine in due time when the engine is not started, and can also stop the work of the starter M in due time after the engine enters the autonomous operation. When the vehicle is normally driven, the working principle of the system is as follows: the driver pushes the AT shift lever into any traveling gear position, when the ignition switch is in an ON position, the engine is not started and the driver does not step ON the accelerator pedal, the accelerator pedal switch K is closed and conducted, AT the moment, the generator does not generate electricity, the resistance of the control circuit of the charging warning lamp W is extremely small, the current output from the ON terminal passes through the resistor R2, the charging warning lamp W reaches the L terminal of the generator and then enters the control circuit of the charging warning lamp W to be grounded, the charging warning lamp W is lightened due to the extremely small resistance of the control circuit of the charging warning lamp W AT the moment, the voltage of the L terminal is made to be close to zero volt, no current enters the positive terminal of the input circuit of the solid-state relay 2, and the output circuit of the solid-state relay 2 is in a cut-off SSR (SSR) conduction state; meanwhile, current output from the ON terminal passes through a resistor R1 and then is grounded through a diode D3 and an accelerator pedal switch K; when a driver steps ON an accelerator pedal, an accelerator pedal switch K is disconnected and is not conducted, meanwhile, as the generator does not generate electricity, the resistance of a control circuit of a charging warning lamp W is extremely small, the current output from an ON terminal passes through a resistor R2, the charging warning lamp W reaches an L terminal of the generator, then enters the control circuit of the charging warning lamp W and is grounded, the resistance of the control circuit of the charging warning lamp W is extremely small at the moment, the charging warning lamp W is lightened, the voltage of the L terminal is made to be close to zero volt, therefore, no current enters a positive terminal of an input circuit of a solid state relay SSR2, the output circuit of the solid state relay SSR2 is in a cut-off and non-conducting state, at the moment, the current output from the ON terminal passes through a resistor R1 and then passes through a diode D2 and a diode D1, a positive terminal of the input circuit of the solid state relay 1, a negative terminal of the input circuit, when the output circuit of the solid-state relay SSR1 is further conducted, the trigger current of the starter M passes through the positive terminal of the output circuit of the solid-state relay SSR1 from the positive pole of the starting power supply and then enters the ST terminal of the ignition switch through the negative terminal of the output circuit of the solid-state relay SSR1, and then the starter M enters a normal engine starting operation state. When the engine is started to enter the autonomous operation state, the engine immediately enters the driving automobile running state, simultaneously the engine drives the generator to generate power, the resistance in the control circuit of the charging warning lamp W in the generator increases sharply, most of the current flowing through the charging warning lamp W enters the positive terminal of the input circuit of the solid-state SSR2 after the current flowing out of IG passes through the resistor R2 and reaches the L terminal of the generator, the negative terminal of the input circuit of the solid-state SSR2 is grounded and the output circuit of the solid-state SSR2 is conducted due to the sharp increase of the resistance of the control circuit of the charging warning lamp W, and then the ON output current enters the positive terminal of the output circuit of the solid-state SSR2 after passing through the resistor R1 and is grounded through the negative terminal of the output circuit of the solid-state SSR2, so that the ON output current no longer passes through the diode D2, the diode D3942 and the diode R1, The diode D1, the positive terminal of the input circuit of the solid-state relay SSR1 and the negative terminal of the input circuit of the solid-state relay SSR1 are grounded, so that the output circuit of the solid-state relay SSR1 is in a cut-off non-conduction state, and then the trigger current of the starter M cannot enter the ST terminal through the output circuit of the solid-state relay SSR 1; thereby stopping the work of the starter M and avoiding the false start operation of the starter.

The invention has the advantages that the system can automatically and timely start the engine through the normal driving operation of a driver, and can automatically and timely stop the starting operation of the starter M and prevent the false starting operation of the starter M after the engine is started.

Detailed description of the preferred embodiments

The timely starting system of the engine comprises: the system is composed of a solid-state relay SSR1, a solid-state relay SSR2, an accelerator pedal switch K, a resistor R1, a diode D1, a diode D2 and a diode D3. When the vehicle is normally driven, the working principle of the system is as follows:

when the ignition switch is in an ON gear, an accelerator pedal is not stepped, and an accelerator pedal switch K is in a closed conducting state, current flows out of an ON terminal and then is divided into two paths, wherein one path of current is grounded through a resistor 2, a diode D3 and the accelerator pedal switch K. Therefore, no current enters the positive terminal of the input circuit of the solid-state relay SSR1, so that the output circuit of the solid-state relay SSR1 is in a cut-off non-conducting state, and no current enters the terminal ST, which results in the non-operation of the starter M. The other path of current passes through the resistor 2, the terminals of the charging warning lamp W and the L, the control circuit (1) of the charging warning lamp W is grounded, the charging warning lamp W is lightened, the engine is not started at the moment, and the generator (2) cannot be driven to generate electricity.

When an ignition switch is in an ON gear, an accelerator pedal is stepped down, and an accelerator pedal switch K is in a disconnected and non-conductive state, current flows out of an ON terminal and then is divided into two paths, wherein one path of current flows through a resistor 2, a diode D2, a diode D1 and an input circuit positive terminal of a solid-state relay SSR1, and then a negative terminal of an input circuit of the solid-state relay SSR1 is grounded, so that an output circuit of the solid-state relay SSR1 is in a conductive state; at the moment, the starting control current flows out from the positive pole (3) of the starting power supply, passes through the positive terminal of the output circuit of the solid-state relay SSR1 and then enters the ST terminal from the negative terminal of the output circuit of the solid-state relay SSR1, so that the starter M enters a working state at proper time to drive the engine to run, and the engine immediately enters autonomous running after being started and drives the automobile to run. During the period that the engine does not enter the autonomous operation, the other path of current passes through the resistor 2, the charging warning lamp W, the L terminal, and the control circuit (1) of the charging warning lamp W is grounded, and the charging warning lamp W is lightened; after the engine is started to automatically run and drive the generator (2) to generate electricity, the resistance of the control circuit (1) of the charging warning lamp W is sharply increased, so that the voltage at the L terminal is instantly increased to be higher than the lowest control voltage of the SSR2, most of the current path passes through the resistance 2, the charging warning lamp W and the positive terminal of the input circuit of the SSR2, and then the negative terminal of the input circuit of the SSR2 is grounded, so that the output circuit of the SSR2 is in a conducting state; then, the current 1 passes through a resistor 2, the positive terminal of an output circuit of the SSR2 and the negative terminal of an input circuit of the SSR2 to be grounded; no current enters the positive terminal of the input circuit of the solid-state relay SSR1, so that the output circuit of the solid-state relay SSR1 is in a cut-off non-conducting state, and therefore, after no current enters the ST terminal, the starter M stops working timely, and the situation that the starter M is in false starting operation is avoided.
