Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a target speed setting device for setting a target speed when a vehicle starts running. [0002] Conventionally, an apparatus called a cycle computer has been known. This cycle computer is composed of a key for inputting the circumference of the bicycle wheel and a target speed, a rotation detection device for detecting the rotation of the wheel, and the like. When an arbitrary value is input by key operation, the value is changed. It is set and displayed as the target speed. Further, the rotation detection device, a magnet mounted on the spoke of the front wheel, a magnetic detection unit fixed to the vehicle body side and located outside the rotation track of the magnet,
A transmitter for wirelessly transmitting a magnetism detection signal from the magnetism detection unit,
And a receiver for receiving a signal from the transmitter. [0003] When the front wheel rotates with the running of the bicycle, and the magnet attached to the spoke passes inside the magnetic detector, the magnetic detector detects the magnetism and the transmitter detects the magnetism. The pulse signal is wirelessly transmitted in synchronization with. Then, the receiver receives the pulse signal, detects the start of the bicycle, counts the passage of the magnet thereafter, calculates the integrated distance by “integrated count number × perimeter”, and “(3600 / count cycle) ) × perimeter ”to calculate the speed (speed per hour), and the calculated integrated distance and speed are displayed on a display unit provided on the receiver side. Therefore, by comparing the previously input and displayed target speed with the calculated and displayed speed, training has been performed so as to increase the speed to the target speed. [0004] However, in the conventional cycle computer, the target speed is set by inputting an arbitrary value by key operation.
Therefore, when the target speed is set low, the training effect by bicycle running cannot be sufficiently expected even if the target speed is achieved. On the other hand, if the target speed is set high, an excessive amount of exercise more than the training level of the user is required, and therefore, it is impossible to set the optimum target speed for obtaining the training effect on the bicycle. It was difficult. SUMMARY OF THE INVENTION The present invention has been made in view of such conventional problems, and has as its object to provide a target speed setting device which can set a target speed suitable for a training level of a bicycle user. It is the purpose. [0006] In order to solve the above-mentioned problems, according to the present invention, there is provided a speed detecting means for detecting a running speed of a vehicle, and the speed detecting means each time the vehicle travels. There is provided storage means for storing the detected maximum speed, and setting means for setting an arbitrary maximum speed as a target speed among a plurality of maximum speeds stored in the storage means. In the above construction, when traveling by bicycle,
The running speed of the bicycle is detected by speed detecting means,
The maximum speed among the detected traveling speeds is stored in the storage means. Then, when the vehicle travels next, the maximum speed stored in advance in the storage means is read out by the setting display means and set and displayed as the target speed. The target speed displayed in this setting is the maximum speed that could be achieved in various past environments and physical conditions, so the training level suited to the condition of the person using the bicycle You can set a goal. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a bicycle 1 to which an embodiment of the present invention is applied.

On the other hand, a transmitter 6 is fixed to the vehicle body 5 of the bicycle 1 outside the rotation path of the magnet 4, and a receiver 7 is mounted on a handle 5 a above the transmitter 6. On the upper surface of the receiver 7, FIG.
As shown in FIG. 1, a display unit 8 constituted by an LCD is provided, and a target setting key 9, a registration key 10, a measurement key 11, and an END key 12 are provided on the periphery. The display section 8 is a display section 8a for constantly displaying the maximum speed stored in a selected maximum speed register described later.
And a display section 8b for displaying other various data. FIG. 3 is a circuit diagram of the transmitter 6. The reed switch 13 is normally off and is turned on when the magnet 4 passes inside the transmitter 6 with the rotation of the front wheel 2,
The reed switch signal a is output to the detection circuit 14. The detection circuit 14 includes an oscillation circuit 15 therein, and upon receiving a reed switch signal a from the reed switch 13, converts the signal into a continuous clock signal b,
To the base terminal of the transistor 19. A capacitor 20 is connected between the collector terminal and the emitter terminal of the transistor 19, the collector terminal is connected to one end of the electromagnetic induction coil 21, and the emitter terminal is connected to the detection circuit 14. Electromagnetic induction coil 21
The voltage Vcc is applied to the other end of the capacitor 22 and one end of the capacitor 22 via the resistor 23, and the other end of the capacitor 22 is connected to the emitter terminal of the transistor 19. Therefore, an electromagnetic induction signal is output from the electromagnetic induction coil 21 in which the clock signal b is supplied to the transistor 19. FIG. 4 is a block circuit diagram showing the configuration of the receiver 7. In the figure, an electromagnetic induction signal from the electromagnetic induction coil 21 of the transmitter 6 is received by a receiving unit 24 having an electromagnetic induction coil (not shown),
Sent to The CPU 25 includes a program RO (not shown).
M, and operates in accordance with the program stored in the program ROM, the data stored in the RAM 26, and the like to control the entire receiver 7 and to control the display unit 8 via the display drive circuit 27. . CPU 25
The key input unit 2 having the plurality of keys 9 to 12
9 and an oscillation circuit 30 for generating a clock signal having a constant frequency, output signals are provided. The RAM 26 is provided with a group of registers shown in FIG. That is, the clock register 26a
Stores the current date and the current time measured based on the clock input from the oscillation circuit 30. The front wheel 2 input by operating a key (not shown) of the key input unit 29 is stored in the tire size register 26b. Is stored. In the traveling speed register 26c,
ON (count) when the magnet 4 passes near the transmitter 6
The current traveling speed (hourly speed) calculated by “(3600 周期 count period) × perimeter” based on the passing count period (second) from the state to the next ON state is stored, and the “integration” is stored in the traveling distance register 26d. The travel distance calculated by “count number × perimeter” is stored. Maximum speed register 2
6e stores the maximum speed as described later, and the selected maximum speed register 26f stores the maximum speed selected by the target setting key 9 as described later. The data register 26g is composed of a plurality of storage areas for storing a plurality of pieces of data each having a set of a registration number, a maximum speed, and a date. In this embodiment according to the above configuration, when the front wheel 2 rotates and the magnet 4 passes inside the transmitter 6,
The reed switch 13 provided in the transmitter 6 is turned on, and a reed switch signal a is generated as shown in FIG. Then, the detection circuit 14 outputs a clock signal b having a predetermined cycle, and the transistor 19 is turned on for a very short time.
Repeat off. As a result, a resonance pulse (electromagnetic induction signal) is output from the electromagnetic induction coil 21 of the transmitter 6 within a short time immediately after the passage of the magnet 4. When a resonance pulse is output from the electromagnetic induction coil 21 on the transmitter 6 side, the electromagnetic induction coil provided in the receiving unit 24 generates a reception signal by an electromagnetic induction action. Therefore, the reception signal is input to the CPU 25 at the timing when the front wheel 2 makes one rotation and the magnet 4 passes inside the transmitter 6, ie, every time the front wheel 2 makes one rotation. Then, CPU2
Reference numeral 5 counts the received signal, calculates the current traveling speed (hourly speed) by “(3600 / count period) × perimeter”, and calculates the traveling distance by “integrated count number × perimeter”. When the power switch (not shown) provided on the receiver 7 is turned on when the bicycle 1 starts running, the CPU 25 starts operating according to the flowchart shown in FIG. That is, first, it is determined whether or not the target setting key 9 has been operated (S1). If the target setting key 9 has not been operated, the process waits until the measurement key 11 is operated (S7). Then, when the measurement key 11 is operated, "0" is stored in the maximum speed register 26e which is the maximum speed storage unit. Thereafter, when the bicycle 1 starts running, the current running speed (hourly speed) and the running distance are calculated as described above (S9), and the calculated running speed and running distance are respectively stored in the running speed register 26c. While storing it in the traveling distance register 26d (S1
0), and displays the stored traveling speed and traveling distance on the display unit 8b.
(S11). Next, the stored and displayed traveling speed is compared with the maximum speed previously stored in the maximum speed register 26e to determine whether or not the speed is greater than the maximum speed (S1).
2). If the result of this determination is that speed> maximum speed, the calculated current speed is stored in the maximum speed storage unit (maximum speed register 26e) (S13). After a while
It is determined whether or not the END key 12 has been operated (S14).
If the END key 12 is not operated, the processing from S9 is repeated. That is, in S12, if speed ≦ maximum speed, the loop of S9 to S12 is executed,
If the speed is greater than the maximum speed, a loop from S9 to S14 is executed. In the loop S9 to S14, the value of the maximum speed is updated and stored in the maximum speed register 26e each time the current traveling speed exceeds the previously stored maximum speed by the determination processing of S12 and S13. go. If the END key 12 is operated when the loop of S9 to S14 is executed, the process proceeds from S14 to S15, and the maximum speed stored in the maximum speed register 26e is displayed on the display 8b. . Thereafter, it is determined whether the registration key 10 has been operated (S16). If the registration key 10 has not been operated, the process proceeds to END, and the registration key 1
When 0 is operated, the maximum speed stored in the maximum speed register 26e is stored in the data register 26g together with the date obtained in the clock register 26a (S17).
That is, as described above, the data register 26g is constituted by a plurality of storage areas for storing a plurality of data each having a set of a registration number, a maximum speed, and a date. Therefore, for example, training is performed a plurality of times using the bicycle 1, and each time the training is completed, the END key 1 is pressed.
2 and the registration key 10, the data register 26
In each of the storage areas g, when traveling as shown in FIG. 7, the n-th maximum speed, the (n + 1) -th maximum speed,
The (n + 2) th maximum speed... Are stored with the date in the order of consecutive registration numbers n, n + 1, n + 2. On the other hand, when the power is turned on when the bicycle 1 starts running and the target setting key 9 is operated, the process proceeds from S1 to S2, and the registration number is incremented. Here, the registration number has been reset to 0 prior to the start of the operation according to this flowchart by an initialization process (not shown). Therefore, when the first operation is performed on the target setting key 9, the registration number 1 is set in S2, and the maximum speed stored corresponding to the registration number 1 is called from the data register 26g together with the date. Is displayed on the display unit 8b (S3). Next, it is determined whether or not the registration key 10 has been operated (S4). If the registration key 10 has not been operated, the process returns to S1. Therefore, registration key 1
If the target setting key 9 is continuously operated without operating 0, the loop of S1 to S4 is repeated, whereby the maximum speed corresponding to the registration number 1 → 2 → 3. It is called sequentially from the data register g and displayed on the display unit 8 together with the date. When the registration key 10 is operated when the maximum speed corresponding to an arbitrary registration number is displayed on the display section 8b, the displayed maximum speed is stored in the selected maximum speed register 26f. Is set as the target speed (S5) and displayed on the display unit 8 (S6). Thereafter, the operation of the measurement key 11 is waited (S7), and the measurement key 1
If there is one operation, the above-described determination processing of S8 to S17 is executed. At this time, the target speed displayed on the display unit 8a is the highest speed that could be achieved in training in various past environments and physical conditions, so that the person using the bicycle The training level can be set to the optimal value according to the conditions of As described above, according to the present invention, the past maximum speeds are sequentially stored in a plurality of storage areas, and the stored maximum speeds are sequentially read out, and any one of the stored maximum speeds is read out. The maximum speed specified in is displayed as the target speed. Therefore, since the target speed set and displayed is the maximum speed that could be achieved in various past training situations, the target speed is set according to the conditions when the person using the bicycle performs training. The optimum target speed can be set and displayed. Therefore, by performing training while visually recognizing the displayed target speed, it is possible to obtain an optimal training effect without excess or deficiency in the amount of exercise performed by the trainee.
