Description of the invention (/) The present invention relates to an improvement of electric vehicle control, in particular to an automatic deceleration control device and method for turning electric vehicles, which provides an unprecedented device for controlling turning. And the method, when the electric vehicle turns, it can automatically force the speed to decrease to a safe set value according to the angle of the turn to prevent the danger of overturning caused by the speed, which is of great practical value and efficacy. Traditional technology and shortcomings Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. Today's electric vehicles, as shown in Figure 1, have three or four wheels, and the speed control method is to dial the speed command lever. The stroke is transmitted to the stable through the controller, and the speed is changed to change the driving speed of the electric vehicle. Or, it adopts the speed control method of rotating the handle, and the control direction is controlled by the handle of the handle, and the rotation angle is controlled by the wheel. Moreover, this electric vehicle is very convenient to use, and it provides an excellent choice for women, men, and the rest. However, there are a lot of problems in travel tools. Disadvantages: (1) Generally, the frame 2 (chassis) of electric vehicles is low and the weight is not heavy, but the height of driving and riding is high (in terms of proportion). ), Which will cause the center of gravity to move higher. In particular, its wheels are small, and they are three or four wheels, not like the two wheels of a locomotive. Therefore, when turning, the effect of changing the angle of the latter two wheels is poor, resulting in a poor effect of adjusting the center of gravity. This phenomenon is especially true in the " "When you turn," it will appear even more. (2) Following the above-mentioned problem of turning the center of gravity, when turning, you must slow down to prevent rollover. For the traditional type, the driver must completely reduce the speed with the handlebar operation. There is no other automatic control device. However, II II — *. 1 In---I-1 -I---I {Please first Read the note on the back # 1 to write this page) -IT-„------ ^ Paper ruler and applicable Chinese National Standard (CNS) A4 specification (2 丨 OX2? 7mm) 4 6 03 92 A7 B7 V. Explanation of the invention (>) Manually operated, there are often "judgment speed error", "operation error (false acceleration) J", "response less than speed reduction J," stubborn not speed reduction J "and other factors. The speed was not properly and properly reduced during the turn, which caused the danger of overturning. The technology and purpose of the present invention are printed by the Consumers' Cooperative of the Central Labor Department of the Ministry of Economic Affairs. Technical means and devices, and presents a "smart 翌 automation" control and efficacy. The main technology and purpose are: First, it is equipped with a pen angle sensing device, which includes a light transmission control sheet, a light projection element, a light receiving element, and a signal processing circuit, so as to sense the angles of "Zoer" and "Right turn" Change, and "straight" status. In addition, the sensing angle is set to automatically sense as the handle is turned, so that the precise variability can be accurately grasped. Second, the power motor is set to accept two control signals, one is "normal phase pulse width change pwm", and the other is "inverted pulse width change change mj" signal, so that the larger the turning angle, the lower The more the PWM value, the smaller the value of Μ, the smaller the electrical energy provided to the motor, and the larger the m of the reverse phase, the greater the reverse braking force generated by the horse stable, so that the electric vehicle can quickly decelerate. Third, it is set to "inductive light amount" and output different control signals, which has the effect of not needing a friction sensor to sense the correct signal, and therefore can be used, does not reduce precision due to friction, and responds quickly Merit

Description of the invention (/) The above is the main technical means of the invention The specific implementation of the present invention is described as follows: 1. In terms of "turning angle sensing device 100": Here is a preferred embodiment, as shown in Figures 6, 7, and 8, like frame 2 A cylindrical body 20 is fixed. A corresponding light-emitting element L1, light-receiving element L2, light-emitting element L1, and light-receiving element L2 are provided with a light-transmitting amount control sheet 10 at intervals. The light-transmitting amount control sheet 10 is provided. There are obliquely extending triangular-shaped left and right light-transmitting holes 11, 12 and left and right light-transmitting holes that do not penetrate between the straight light-shielding portions 13, and the light-transmitting amount control sheet 10 is pseudo-handle vertical bar 1 It is set as a skeleton, which can change the positions of the light-transmitting hole and the light-receiving element corresponding to the left and right light-transmitting holes and the vertical light-shielding part 13 with the rotation of the handle bar, so that the light-receiving element L2 can perceive different changes in the amount of light. Changes in turning angle. Second, in terms of the "control circuit": As shown in Figure 4A, the light-emitting element L1 is provided with a resistor R1 to limit the current of the light-emitting element, and the light-receiving element L2 is provided with another resistor R2. When the photocurrent flows through the resistor R2 A potential is generated, and an amplifier circuit A1 with an adjustable variable resistance VR is provided to amplify the signal of the light amount voltage change sensed by the light receiving element L2 and adjusted to rotate 40 degrees. At the maximum light amount, the maximum output is 10 units. Then lost to the complete computer processor MCU. On the motor side, it is equipped with two power crystal mushrooms Ql and Q2, which respectively accept positive and reverse pulse widths to convert PVM and FTff signals to generate different PWM width values. The motor can generate different speeds according to the width of the PWM. After understanding the technical means and component implementation of the present invention, the actions and controls of the present invention will be described in detail below: (Please read the notes on the back 7% first to write this page) Installation. Thread_b_ This paper size Applicable to China National Standard #CNS (A4) (210X297 mm) d 6 03 92 A7 Printed by the Consumers ’Cooperative of the Central Government Standards Bureau of the Ministry of Economic Affairs B7 V. Description of the invention (1) When traveling straight without change: its The turning angle sensing device 100 is in a state as shown in FIG. 8 (A). The projection and light receiving elements L1 and L2 are completely blocked by the direct light shielding portion 13 of the light transmission amount control M10. The light receiving element cannot accept To the light source, its output voltage is the smallest, that is, it has almost no output control signal to the computer processor MCU. As shown in Figures 2 and 5, the signal received by the MCU is only the speed value of the handle speed command, which is 100. The output of% is given to the power output stage. 2. When turning: Turn right and left, as shown in Figures 8 (B) and (C), the light transmission amount control sheet 10 is indexed accordingly, and the right light transmission hole 12 (left light transmission hole 11) follows The increase of the right (left) rotation angle increases the area of the light transmitting hole, so the light receiving element L2 can increase the output voltage according to the area of the light transmitting hole. As shown in Figure 4A and B, the light receiving element L2 A potential VI is generated by the amplifier circuit A1 to remove the computer processor MCU. It has positive and reverse pulse widths PW M, F ¥¥ signal output. When the PtfM signal is input to the power crystal Q2, Q2 is turned on, and then positive The potential V + is input to the positive and negative poles of the motor, and then passes through the C pole of power crystal Q2, and then through the E pole of power crystal Q2 to the negative potential V- to form a complete circuit. The motor can follow this The width of the PWM produces different speeds. That is, as shown in Figures 2 and 3, the HCU first reads the turning angle sensing device signal command to set the upper limit of the duty cycle PWM duty cycle, then reads the handle speed command, and outputs positive and negative PWM and m after the calculation. The control signal is shown in Figure 5. The larger the turning angle, the larger the light receiving area (please read the precautions on the back to write this page) -0 This paper size applies to China National Standard (CNS) A4 specifications (210X297 mm) 460392 A7 B7 is printed by the Consumer Cooperatives of the Central Procurement Bureau of the Ministry of Economic Affairs. 5. Description of the invention (6), so that the output value of PW M becomes smaller. Therefore, the motor speed is reduced. Therefore, in addition to the speed control of the handle, the speed of the motor has priority over the main control. The angle of the rotation angle sensing device is pseudo-received, and it senses different amounts of light and outputs pulse signals with different widths. This width is controlled.说明 Explained by the actual "Lotus calculation": The output value of the handle speed command is "X" and the maximum value is set to 10 units. The output value of the turning angle sensing device is "y", and the maximum value is set to 10 痼 units (100%). The maximum value of the output value "z" after the calculation is also 10 痼 units. The output value of z can be obtained according to the calculation formula of z = x · y / Ι ◦ Example: ① The MCU reads the value of y as 0 when going straight, as shown in Figure 51 (B). Relative to Figure 5 (A), set the maximum output value at this time to 100%. If it input is "10", then z = 10X10 / 10 = 10 (maximum round output 100¾ duty pwh). If x input is "5" z = 5x10 / 10 = 5 (―half output 50% duty pw α) ② y value = 5 when turning 20 degrees, if X input is “10”, ζ = 1〇 × 5 / = 5 (—half output 50 % duty pwm) If x input is "5", then z = 5X5 / 10 = 2.5 (1/4 output 25% duty pwm) It can be seen from the above that whether the value of x or y changes, the value of z will change accordingly.

Description of the Invention (7) Ministry of Economic Affairs Printed by the Consumer Standards Cooperative of the Central Bureau of Standards. Then output this changed PWIE to the motor, you can change the speed of the motor. 0 The above control does not require manual judgment and deliberate control. It can automatically change the control according to the turning angle. It reacts quickly and turns down when it turns. Safety effect. Third, the present invention has an excellent effect on the stable of the horse: once the motor (electric vehicle) is supplied with voltage, it will turn. If it is stopped, the supply voltage will be lowered to zero, but the horse (Electric vehicle) will continue to rotate and glide due to the original inertia of rotation, the higher the speed. The greater the inertia, the longer the taxi distance. After stopping, the electromagnetic brakes are used to calm the stirrup shaft, so that the motor (electric vehicle) can no longer slide or slide down the slope. The invention adds a "dynamic brake stage", the purpose of which is to quickly consume the inertia and reduce the taxi distance, so that the motor (electric vehicle) can quickly reduce to the required speed when turning at high speeds to achieve a comfortable and safe vehicle speed. As shown in Figure 4B, when the normal-phase pulse width modulation PWM signal value is 0, the power crystal Q2 does not turn on, and there is no power for the horse. However, the motor is still rotating due to the previous lotus rotation, which generates inertial momentum. It can be described as "the effect of a generator (using non-electric power to rotate the motor shaft, which will generate electricity) J. At this time, a signal is sent to the power crystal Q1 to be turned on, because Q1 is connected to the motor (at this time, it is issued The effect of the motor) is formed by the load of the motor (generator). The current of the internal line of the horse stable will generate "reverse flow", which will cause a reverse torque, which can make the horse stable. Also returned to non-generator status). That is, the present invention makes good use of the "motor inertia rotation" (please read the notes on the back r4 first copy f) This paper size applies the Chinese National Standard (CNS) A4 specification (2 [0X297 mm) 4 6 03 9 2 A7 Printed by B7 Consumers Cooperative of Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention () Reverse current can generate reverse torque. For the purpose of "dynamic braking", the brakes are not used to make the brakes. dead. In addition, according to the above-mentioned principle of turning the horse to control the speed of the stable, the turning angle sensing device of the present invention can also be set as a "sliding contact" variable resistance and magneto-electric potentiometer to sense different potentials of angle changes. , Also show the creative scope of this invention. In summary, the control method of the present invention does not have the same method first in the field of electric vehicle items. The practical effect achieved also has excellent practical value.
