Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a constant speed traveling control device for a vehicle that sets a vehicle speed desired by a driving vehicle and travels the vehicle at a constant speed.

(Prior Art) As a constant speed traveling control device mounted on a vehicle, the vehicle speed information obtained from the vehicle speed detection means is displayed on the vehicle speed display means, and a predetermined target vehicle speed is set by a set signal of the vehicle speed setting means. There is one that controls the traveling speed of the vehicle so as to match the target vehicle speed.

Conventionally, in order to display the vehicle speed information obtained from the vehicle speed detecting means, an analog display is made by a mechanical speedometer pointer, and the target vehicle speed is set based on the displayed vehicle speed by a set switch which is a vehicle speed setting means. The mechanical speedometer does not have good followability for acceleration and deceleration.

Moreover, since the vehicle speed information displayed by the speedometer and the target vehicle speed information of the constant speed traveling control device are controlled in different series, there is a slight difference between the actual traveling speed and the displayed vehicle speed.

Therefore, for example, when the target vehicle speed is set by pressing the set switch based on the displayed vehicle speed displayed on the speedometer during acceleration, the actual traveling speed is faster than the displayed vehicle speed.
The vehicle will run at a constant speed at a value that exceeds the displayed vehicle speed.

On the other hand, for example, if the set switch is pressed during deceleration to set the target vehicle speed, the actual traveling speed is slower than the displayed vehicle speed as opposed to during acceleration, so the vehicle travels at a constant speed lower than the displayed vehicle speed.

(Problems to be Solved by the Invention) As described above, the vehicle speed information displayed by the speedometer and the target vehicle speed information are controlled by different systems, and the vehicle speed display configuration of the speedometer is mechanical. The vehicle may run at a speed different from the vehicle speed desired by the person.

Therefore, there is a method of correcting the disagreement between the actual traveling speed and the displayed vehicle speed so that the vehicle travels at a constant speed at a desired speed, but the structure for detecting and correcting the difference is complicated and it is difficult to correct it accurately. Is.

The present invention has been made against the background of such circumstances, and it is possible to accurately set a target vehicle speed for constant speed traveling regardless of the driving situation, and to set a constant vehicle speed at which the driver can drive at a constant speed. An object is to provide a high speed traveling control device.

(Means for Solving Problems) In order to solve the above-mentioned object, the present invention inputs a detection signal from a vehicle speed detecting means to a control means, obtains vehicle speed information displayed by the control means, and sets a vehicle speed. It is characterized in that the display vehicle speed information is set as the target vehicle speed information by the set signal.

(Operation) In the present invention, the detection signal from the vehicle speed detection means is input to the control means, and the display vehicle speed information is obtained by this control means. When the vehicle speed setting means is operated, a set signal is input to the control means, and the display vehicle speed information is set as the target vehicle speed information by the set signal.

As a result, the displayed vehicle speed displayed on the vehicle speed display and the set target vehicle speed match, so that the desired vehicle speed is accurately set even when the driver sets the vehicle speed during acceleration or deceleration. .

(Embodiment) An embodiment of the present invention will be described in detail below with reference to FIG. FIG. 1 is a basic configuration diagram of the present invention.

In the figure, reference numeral 1 is a vehicle speed detecting means, and a pulse signal output from the vehicle speed detecting means 1 is input to a control means 2. The control means 2 is composed of a vehicle speed calculation means 3, a vehicle speed storage means 4, a vehicle speed set request means 5 and a target vehicle speed storage means 6.

The pulse signal output from the vehicle speed detecting means 1 is input to the vehicle speed calculating means 3 as information on the traveling distance, and the vehicle speed calculating means 3
Then, the vehicle speed is calculated from the information on the traveling distance and the information on the time. The vehicle speed information from the vehicle speed calculation means 3 is stored in the vehicle speed storage means 4, and this vehicle speed information is input to the vehicle speed display means 7. The vehicle speed display means 7 displays the vehicle speed based on the vehicle speed information.

When the vehicle speed set requesting means 5 operates and the set signal is input from the vehicle speed setting means 8, the target vehicle speed storage means 6 stores the vehicle speed information of the vehicle speed storage means 4 in the target vehicle speed storage means 6. Then, the constant speed traveling control means 9 is driven based on the target vehicle speed stored in the target vehicle speed storage means 6.

2 to 5 show the invention applied to a motorcycle,
Further specific examples will be shown.

In FIG. 2, reference numeral 21 is a speed sensor which is a vehicle speed detecting means, and a pulse signal obtained from the speed sensor 21 is inputted to a one-chip microcomputer 23 which is a controlling means through an input interface 22.

The one-chip microcomputer 23 calculates the vehicle speed from the pulse signal and stores the vehicle speed information in the actual vehicle speed storage memory of the RAM for each calculation. Then, this vehicle speed information is output via the output interface 24 to the LCD which is a vehicle speed display means.
It is output to the meter 25 and is digitally displayed on the LCD meter 25.

When a set signal is input to the one-chip microcomputer 23 from the set switch 26 which is a vehicle speed setting means, the vehicle speed information in the actual vehicle speed storage memory of the RAM is stored in the target vehicle speed storage memory. Then, this target vehicle speed information is output to the constant speed traveling control means 28 via the output interface 27, and the traveling vehicle speed of the vehicle is controlled to reach the target vehicle speed.

The constant speed traveling control system for this vehicle is arranged as shown in FIGS.

A fairing 31 is provided on the motorcycle so as to cover both sides of the vehicle body from the front side, and a display device 32 is incorporated in the fairing 31 at a position on the front side of a handlebar 33.

(Step b).

Next, it is judged whether or not a vehicle speed setting request is made by operating the set switch 36 (step c), and if the set signal is input, that is, if there is a constant speed traveling set request, the actual vehicle speed is set. The vehicle speed information in the storage memory is stored in the target vehicle speed memory (step d). Then, the vehicle speed information in the actual vehicle speed storage memory is transferred to the meter display area (step e), and the vehicle is driven at a constant target vehicle speed,
