TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field of a vehicle speed control device for executing a vehicle speed control based on a set vehicle speed based on a driver's set operation or a relative positional relationship with a preceding vehicle with the set vehicle speed being an upper limit.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a display device of a vehicle speed control device for a vehicle, for example, a display device described in JP-A-2000-118263 is known.
[0003]
In this conventional publication, the information on the vehicle speed (set vehicle speed, set upper limit vehicle speed, low speed limit vehicle speed) used in the vehicle speed control device is displayed in a region in association with the own vehicle speed, so that the driver can control the vehicle speed control state. A technique is described that makes it easy to grasp.
[0004]
[Problems to be solved by the invention]
However, in the display device of the conventional vehicle speed control device, after the vehicle speed control is started, if the control is interrupted due to a driver's operation or the like, it is possible to return to the control at the set vehicle speed before the release of the control. The driver cannot know from the displayed information on the vehicle speed itself whether or not it is possible to simply start the vehicle speed control.
[0005]
That is, when the cruise system main switch is ON and the traveling vehicle speed is 50 to 100 km / h, when the set / coast switch is pressed, the vehicle speed control device having the constant speed traveling control function and the preceding vehicle following control function is used. Is stored as the set vehicle speed, and vehicle speed control is started.
[0006]
After the vehicle speed control is started, for example, when the brake pedal is depressed, when the select lever is set to other than “D”, when the traveling vehicle speed falls below about 40 km / h, the control is interrupted, When these control interruption reasons are eliminated and the traveling vehicle speed becomes about 50 to 100 km / h, the control returns to the control at the set vehicle speed before the control interruption by pressing the resume / accelerate switch.
[0007]
However, the driver is not informed of the information that the control can be returned to the control at the set vehicle speed before the control interruption or the direct information that the vehicle speed control can be started. In fact, it is unclear whether control return or control start is possible.
[0008]
The present invention has been made in view of the above-described problem. After the vehicle speed control is started, control resumable information in a state where control is interrupted due to a driver's operation or the like, or mere control startable information is directly transmitted to the vehicle. It is an object of the present invention to provide a vehicle speed control device that can inform a driver of the vehicle speed.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, a vehicle speed control device for executing a vehicle speed control based on a relative position relationship with a preceding vehicle with the set vehicle speed set as an upper limit or a set vehicle speed based on a driver's set operation, After the vehicle speed control is started, when the vehicle speed control is suspended due to interruption of the vehicle speed control, and when the set vehicle speed is stored, a return control enabled state display that indicates that it is possible to return to the stored set vehicle speed is possible. Means and a control startable state display for indicating that the vehicle speed control can be started when the vehicle is in a control standby state due to no start instruction of the vehicle speed control being issued and the vehicle speed is in the vehicle speed controllable region. Among them, at least one of the means is provided.
[0010]
Here, "during control standby due to suspension of vehicle speed control" means, for example, that after the vehicle speed control is suspended due to the satisfaction of the control suspension condition among the vehicle speed control release conditions, the control suspension condition is resolved and the vehicle speed control returns to the original vehicle speed control. Means a running state waiting for the return of the vehicle.
[0011]
The "return control-possible state display means" and "control start-possible state display means" are means for allowing the driver to visually recognize each state during traveling (although it may be accompanied by a voice). By using the vehicle speed display unit, the whole number displayed in the segment of the set vehicle speed display unit is blinked, the arranged numbers are switched right and left, and the numbers are rotated and blinked. Further, a first display unit and a second display unit may be provided as the set vehicle speed display unit to distinguish between the two types of status display. Further, the first display unit and the second display unit may be arranged corresponding to the positional relationship between the return control start switch and the vehicle speed control start switch.
[0012]
【The invention's effect】
Therefore, according to the present invention, after the vehicle speed control is started, the vehicle is in the control standby state due to the suspension of the vehicle speed control, and when the set vehicle speed is stored, the reset control enabled state display means displays the stored setting. It is displayed that it is possible to return to the vehicle speed, or control is possible when the vehicle speed is in the vehicle speed controllable area while the control is in a standby state because the vehicle speed control start instruction has not been issued. On the display means, it is displayed that the vehicle speed control can be started, so that the control returnable information in a state where the control is interrupted due to the driver's operation or the like after the start of the vehicle speed control, or the simple control startable information is displayed. The driver can be notified directly as information.
