Abstract

This invention provides a motor driven golf cart which is mounted with a power generating and charging device and enables the selection of a ""generator stop mode"" and a ""charge mode"" in addition to an ""ordinary travel mode"". It is first decided whether the mode is the charge mode or not (S21). In the case of the charge mode, an engine for driving the generator is turned on to start (S22). Next, it is decided whether the engine is started or not (S23). When the engine is decided to be started, the magnitude of charge current (charge quantity) is decided (S24). When the charge current is large, judgment is made that the charge is still necessary. When the discharge quantity is small, the charge quantity is large and judgment is made that the replenishing discharge is not necessary any more. The engine for driving the generator is then turned off to stop (S25). When the mode is judged not to be the charge mode (S21), it is decided whether the mode is the ordinary travel mode or not (S26). When the mode is judged to be the ordinary travel mode, the control meeting the flow of the power generation and charge control sequence is executed as the ordinary travel mode (S27). When the mode is judged not to be the ordinary travel mode, the engine for driving the step generator is turned off to stop (S28).

V. Explained in detail (8) According to the golfer ’s operation, “Secondly, after“ automatic, automatic ”,“ become self, slightly C driving the road) buried together ”using the left and right guides to reference the differential amplifier to get the difference The direction of Xingjing is' by reading the speed of the magnet arrangement, performing automatic operation and automatic road driving. It also moved forward and stopped by remote control. The safety device detected a situation with the danger detection device and stopped because of a fixed distance. In the above structure, (including downhill), the charging current value detected by the power source (battery) 11 which stops the power source 2 6. Here, the focus is on charging and other disturbances such as load fluctuations and preventing the battery from being overcharged. In addition, the golf ball can move forward and backward in the "normal driving mode". If this happens, set the automatic operation switch lever to the dynamic driving mode. At that time, the guide current flowing along the circuit line of the freight car was used as a guide sensor to detect it. After being amplified and detected, it was output through the moving wheel and was input to the main CPU 23 by analog signals. Information such as the stop of benefits buried on the road (traveling road) can be used at the transport lane or the forward / stop buttons to accelerate and decelerate and stop automatically according to the instructions of the main CPU 23.

Especially when using a transport vehicle to protect the automatic stop action and keep a certain golf transport vehicle of the present invention at a distance from the preceding vehicle, the current detection circuit 24 is used to directly monitor the discharge current value and the charging current value of the system, and The discharge current value is periodically stored in the memory electric current value and the discharge current value due to the detection of the charging and discharging status of the stable battery and can be monitored. Turn the key switch 30 in FIG. 6 to the solid line position, according to Position θ of the rotating shaft 31 rotating with it

Page 13 V. Description of the invention (9) After setting the signal to the main CPU 23, it is determined that it is in the normal driving mode, and the golf cart is driven under the following general charging operations. That is, while the golf cart is running, the main CPU 23 determines that when the current detection circuit 24 increases in discharge current value and becomes larger, and the amount of charge of the battery decreases, the engine that drives the generator 10a of the power generation and charging device 10 is started. The battery 11 is charged via the charger 1 Ob. Then, the charging current value is checked by the current detection circuit 24, and when the discharging current value decreases below a predetermined value, the engine is stopped 'to end the charging operation. In this way, every time the golf cart starts running, the current detection circuit 24 is used to check the discharge current value and perform the same charging operation. If the golf transport vehicle is stopped, start the engine of the generator 10a that drives the power generation and charging device 10. After determining that the engine is started, use the current detection circuit 24 to check the charging current value. If the charging current value is more than a predetermined value, The battery 11 is charged via the generator 10a and the charger iOb, and the charging operation is continued until the charging current value becomes equal to or lower than a predetermined value. In addition, the current detection circuit 24 is used to check the charging current value. If the charging current value is less than a predetermined value, the bow will stop and the golf cart will stop in a waiting state. If driving is started again next time, the current detection circuit 24 is used to check the discharge current value. In addition, because the current detection circuit 24 is used to directly monitor the discharge current and charge current of the power supply (battery), and the detected charge current and discharge current are periodically stored in the memory 26, regardless of The golf transporter can grasp the state of charge of the battery during driving and stopping, and it can be recharged reliably after the charging period. Especially when the golf cart is stopped ’because it ’s not necessary to check the charging current value to confirm the battery charge.

And the special start engine, and 'for the purpose of power generation and golf in order to gather the spirit, stop the motor mode' after the signal, the main CPU 23 stops relying on the charged battery to disturb 'can enjoy quietly without additional The engine of the noise charging device 10 is at the charging source whenever the golfer wishes to rotate the whole key switch 30 to the knob 3 2 turns on the basis of turning with it. Therefore, do not play golf. Noise occurred during the drive, and each round kept quiet and electrically operated to the position of the "rotating shaft 31" shown by the dashed line. It was controlled so that it would only be affected by the engine sound in the "generator stop mode". Most of the stored electricity has been reduced, and it is necessary to pre-charge electricity for the next drive. Therefore, before storing in the transportation compartment, 'turn the knob 32 of the key switch 30 to the "charging mode" shown by the dashed line, and according to the position signal of the rotating shaft 31 that rotates with it, the golf cart is stopped, The main cpu 23 also commands a predetermined charging operation. That is, the engine of the generator 10a that drives the power generation and charging device 10 is started, and the battery U is charged through the charger 10b. Then, the charging current value is checked by the current measuring circuit 24. When the charging current value decreases to less than a predetermined value, the engine is stopped and the charging operation is ended. In addition, in the "normal driving mode", the battery can be recharged by using the regenerative braking of the motor 13 for driving the golf transport vehicle during braking, in addition to the power generation and charging device 10. Therefore, the present invention does not charge the battery Π in the transportation compartment of the golf course, but uses the power generation * charging device 10 to charge it at any time on the course. It is also possible to use small fuel cells in power generation and charging equipment.

Description of the invention (11)-Second, according to the flow of the power generation and charging control sequence shown in Fig. 4, the power generation * charging control of the electric golf cart in the general driving mode as the object of the present invention will be described. In FIG. 4, starting from step s0 power generation and charging, it is determined in step S1 whether the golf cart is running. If it is "in the case of a line", the process proceeds to step S2, and in step S2, the magnitude of the discharge current (discharge amount) is determined. In the case where the discharge current is small, the judgment is that the amount of discharge is small, and it is not necessary to supplement the determination of the magnitude of the repeated discharge current after charging. When the discharge current is large, it is judged that the discharge amount is large, and the process proceeds to step S3 to start the engine for driving the generator. It is determined at step S4 'whether the engine is started. If the engine is not started (NG), go to step S3 and try to start the engine for generator driving. If it is determined that the engine is started, the process proceeds to step S5 to determine the magnitude of the discharge current (discharge amount). If the discharge current is large, it is judged that the discharge amount is still large, and the same determination of the magnitude of the discharge current is repeated. If the discharge current is small, it is judged that the discharge amount is small without recharging, and the process moves to step S6 to stop the engine for driving the generator. Then 'return to step' and repeat the same control action. If it is determined in step S1 that the golf cart is stopped, the process proceeds to step S7 to start the engine for driving the generator. Next, at step S8, it is determined whether the engine is started. If the engine is not started (NG), go to step S7 and try to start the generator. If it is determined that the engine is started, go to the next step S9 to determine the charging current (charge amount). Its size. When the charging current is large, it is judged that the charge is still small, and the same is repeated.

After the charging current is small and no additional charging is required, move to the step and the situation is judged to be the amount of charge. The engine is stopped. ‘Stop the generator drive. Stop the generator drive engine and check whether the transport vehicle is running. If it is determined that Gore-in-Step S11 determines that the golf ball has the same determination action. In the judgment of step s i, the wheeled vehicle system is stopped, and the vehicle is restarted. Then, the process proceeds to step S2, and the golf cart mode is repeated. Next, the control mode during driving is described with reference to FIG. 5 among the various modes of the electric power generation and charging f control of the present invention added to the control sequence of FIG. "Motor stop mode" select "driving mode" electric mode. * It is the charging mode. Go to step = 2 \: determine whether it is the charge. It is determined that the start sound generator a is not as good as this, it is the feeling of not starting (No), and then it returns to the step engine; otherwise, it starts. . If the engine used to drive. If it is determined that the May 'trial start generator fixed charge secondary engine is started, the process moves to step S24 to determine the magnitude of the electric packet current (charge amount).

It is judged that the charging current needs to be recharged if the charging current is large. The size of the judgment.判断 If the charging current is small, it is determined that the charging is 0. After recharging is not necessary, move to step S25 'to stop the bow of the generator driving function. If β is determined in step S21, if it is determined that the charging mode is not in step S26, the process proceeds to step S26 to determine whether it is in the normal driving mode. If it is judged that the driving mode is normal, go to step
