Please refer to Figure 5, which is a first schematic diagram of the electric control system of the embodiment of the present invention connected to the mobile vehicle.

The electronic control system SYS1 is connected to the vehicle computer V10 of the mobile vehicle V1. The drive circuit V11, the battery unit V12 and the sensor module V13 are all connected to the vehicle computer V10. In this embodiment, the electronic control system SYS1 needs to obtain the information of the drive circuit V11, the battery unit V12 and the sensor module V13 through the vehicle computer V10 to obtain the relevant information.

In Figure 5, the sensor module V13 is connected to the vehicle computer V10 via a controller area network system (CAN) or a KLINE system.

Please refer to Figure 6, which is a second schematic diagram of the electric control system connected to the mobile vehicle according to an embodiment of the present invention.

The control circuit 1 of the electronic control system SYS1 is directly connected to the sensor module V13. The first energy-saving strategy circuit 11, the second energy-saving strategy circuit 12 and the third energy-saving strategy circuit 13 of the control circuit 1 can directly access the signals of multiple sensors of the sensor module V13. In Figure 6, the control circuit 1 has the function of analyzing the communication protocol of the sensing signal of the sensor module V13.

Please refer to FIG. 7, which is a functional block diagram of the sensor module of the mobile vehicle. The sensor module V13 includes a throttle position sensor V131. The throttle position sensor V131 detects a throttle position of the mobile vehicle V1.

The throttle position sensor V131 detects a throttle position of the mobile vehicle V1 and is used to provide multiple throttle position signals to the first energy-saving strategy circuit 11 of the control circuit 1.

The throttle position sensor V131 provides at least a first throttle position signal, a second throttle position signal and a third throttle position signal. The first throttle position signal is a throttle position signal when the throttle position is in a slightly open position. The second throttle position signal is a throttle position signal when the throttle position is in a half-open position. The third throttle position signal is a throttle position signal when the throttle position is in a fully open position.

In other embodiments, the throttle position sensor V131 can provide throttle position signals of three or more levels, such as but not limited to four, five or seven levels, which are not limited in the present invention.

Please refer to Figures 7 and 8. Figure 8 is a schematic diagram of one of the multiple energy-saving strategies of an embodiment of the present invention.

The sensor module V13 includes a rotation speed sensor V134. When the mobile vehicle V1 is in an acceleration state, the second energy-saving strategy circuit 12 of the control circuit 1 controls the drive circuit V11 to not charge the battery unit V12.

When the mobile vehicle V1 is in a deceleration state, the second energy-saving strategy circuit 12 of the control circuit 1 controls the drive circuit V11 to charge the battery unit V12.

The acceleration state and the deceleration state are when the speed sensor V134 detects that the speed of the mobile vehicle V1 in a first interval in an earlier time interval T1 is different from the speed of a second interval in a later time interval T2. The earlier time interval T1 and the later time interval T2 can be adjacent time intervals. Or, there is a period of time between the earlier time interval T1 and the later time interval T2. The acceleration state is when the speed of the first interval is less than the speed of the second interval. The deceleration state is when the speed of the first interval is greater than the speed of the second interval. The earlier time interval T1 and the later time interval T2 are equal time intervals.

Please refer to Figure 9, which is another schematic diagram of one of the multiple energy-saving strategies of an embodiment of the present invention.

The sensor module V13 includes a power sensor V135 for detecting a battery voltage of the battery cell V12.

The voltage range is 13.5V+/-0.5V.

That is, at this time, the driving circuit will not provide current I2 to the battery cell V12. The battery cell V12 will not provide power (current I3) to the load LOAD.

Please refer to Figure 7 and Figure 10. Figure 10 is another schematic diagram of one of the multiple energy-saving strategies of the embodiment of the present invention.

When the power sensor V135 of the sensor module V13 detects that a power range of the battery cell V12 is greater than a first power range, the third energy-saving strategy circuit 13 of the control circuit 1 controls the drive circuit V11 not to charge the battery cell V12.

When the power sensor V135 of the sensor module V13 detects that a power range of the battery cell V12 is greater than a second power range and less than the first power range, the third energy-saving strategy circuit 13 of the control circuit 1 controls the drive circuit V11 to charge the battery cell V12.

When the power sensor V135 of the sensor module V13 detects that a power range of the battery cell V12 is less than a third power range, the control circuit 1 controls the drive circuit V11 to charge the battery cell V12.

In this embodiment, the control circuit 1 also includes a strategy selection circuit 14.
