DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an acceleration display device for detecting longitudinal acceleration and lateral acceleration of a vehicle and displaying the information to a vehicle occupant for notification.

[Conventional technology]

As a conventional acceleration display device, there is one shown in FIG. 3, for example. It detects the longitudinal acceleration and lateral acceleration of the vehicle and combines the longitudinal direction, the lateral direction, the longitudinal direction and the lateral direction depending on the purpose of the occupant, and the elapsed time from the stopped state of the vehicle to the mileage of 400 m. Is selectively notified by a graphic display, a level indicator, a spacer, or the like.

The case 1 is installed at a position such as a vehicle instrument panel that is easily seen by an occupant, and the switch 1 (3-1),
Switch 2 (3-2), Switch 3 (3-3), Switch 4 (3-4), Switch 5 (3-5), Switch 6
(3-6), switch 7 (3-7), level indicator 4, graphic display 5, speaker 7, and volume 8 are used to support them.

The signal processing unit 6 is a notification data generating means that is installed at an appropriate location of the vehicle and detects longitudinal acceleration, lateral acceleration, vehicle speed, and calculates and outputs notification data based on these detection signals.

The more detailed structure and operation will be described below with reference to the block diagram of FIG. The front-rear sensor 6-1 outputs a certain reference voltage when the acceleration is zero with respect to the front-rear acceleration of the vehicle. A voltage proportional to the magnitude of acceleration is output. Left and right sensor 6-
Similarly, 2 also outputs a certain reference voltage when the acceleration is zero, and outputs a voltage proportional to the magnitude of the acceleration in the positive direction from the reference voltage in the right direction and in the negative direction from the left direction from the left direction. The vehicle speed sensor 6-3 detects the rotation speed of the vehicle on the side of the transmission wheel shaft and outputs a frequency or voltage proportional to the rotation speed.

The arithmetic processing unit 6-4 calculates various notification information based on the output signals of the front-rear sensor 6-1, the left-right sensor 6-2, and the vehicle speed sensor 6-3, and switches 1 (3-1), switch 2 ( Three
-2), switch 3 (3-3), switch 4 (3-
4), switch 5 (3-5), switch 6 (3-6),
Information is selectively notified by the speaker 7, the display 5, and the level indicator 4 according to the state of the switch 7 (3-7).

Next, a method of calculating various notification information, a method of selecting notification information, and a specific notification method will be described with reference to the flowchart of FIG.

After the start, in step 101, mode 1 is set as the initial state. In step 102, the switch 1 is a selection switch for mode 1, mode 2, and mode 3, and every time the switch 1 is turned on, the processing of steps 117 to 121 causes Is selected. In step 103, the switch 2 is a selection switch for mode 4 and mode 5, and each time the switch is turned on, the process of steps 122 to 124 causes Is selected.

Mode 1 is a front-rear G (acceleration) mode and displays as shown in FIG.

The current level G on the level indicator 4 and the display unit 5-2
Is displayed. Before and after the peak G is displayed on the display unit 5-3.
The inclination angle of the climbing plate is displayed on the display unit 5-4.

In the display unit 5-1, the horizontal axis represents time, and the change state of G before and after a certain time is graphically displayed.

Mode 2 is the left and right G mode, and displays as shown in FIG. The current left / right G is displayed on the level indicator 4 and the display unit 5-2. The peak left and right G are displayed on the display unit 5-3. The radius of gyration in the curve is displayed on the display unit 5-4. The display unit 5-1 has a vertical axis representing time and left and right G for a certain time.
The change situation of is displayed graphically.

Mode 3 is a front / rear / left / right composite G mode, and displays as shown in FIG.

The current front / rear / left / right composite G is displayed on the level indicator 4 and the display unit 5-2. The peak front-rear left-right composite G is displayed on the display unit 5-3. An alarm front / rear / left / right composite G set by the occupant is displayed on the display unit 5-4, and when the current front / rear / left / right composite G exceeds this, the speaker 7 gives an alarm. Display 5-1
Indicates the front-rear and left-right combined G with the vertical axis front-rear G and the horizontal axis left-right G.

Mode 4 is a full graphic mode, and displays as shown in FIG.

The level indicator 4 and the display section 5-6 show the current front and rear G
Is displayed. The display unit 5-5 displays a picture of a road, a picture of trees on the roadside, and the like, and the speed at which the picture on the roadside flows changes according to the vehicle speed. Further, the curvature of the road changes depending on the size of the left and right G, as shown in FIG.

Mode 5 is sports mode 1 and displays the display shown in FIG. This is to measure the time required to start the vehicle from a stopped state and travel a certain distance, and display the same as in mode 1 except that the display section 5-4 displays the measured time.

Mode 6 is sports mode 2, which measures the time required for the vehicle to start from a stopped state and reach a constant vehicle speed, and the same display as in mode 5 is performed.

The switch 3 in step 104 has steps 125 to 127,132.
When turned on in modes 1 to 3 of ~ 134, the peak G value of the mode is reset. In mode 128, step 128, nothing is done. In the case of turning on for the first time after the end of measurement in mode 5 and mode 6 of step 129 (flag a = 0), the process proceeds to step 130, and the present measurement result and the past measurement result are displayed in order of rank, as shown in FIG. To do. In step 131, the flag a = 1 is set to indicate that the measurement result has been displayed. When the switch 3 is turned on again, the flag a = 0 is set in step 135, and the measurement in the same mode is performed again in step 136.

In step 105, step 4 includes steps 137, 138, 14
As shown in 2,143, when it is turned on in the sports mode (mode 5, mode 6), every time it is turned on And the mode changes. Step 140,141,145
Is turned on in Modes 1 to 4, the flag b is set every time it is turned on. Then, the flag b = 1 has a pause function of fixing the display of the display portions 5-1 and 5-5 to the state at that time.

The switch 5 of step 106 is a switch for the occupant to set the alarm G, and one of the steps 146 increases the alarm G and the other of the step 147 of the step 5
Set to reduce alarm G.

The switch 6 in step 107 is for automatically displaying the turning point on the return route by inputting the turning point on the outward route when going back and forth through an unfamiliar place on the road. Each time it is turned on, the mileage and cornering radius at that time are stored (step
148, 149), and the switch 7 in step 108 is turned on at the start point of the return path, so that the reproduction of the data stored in the outward path in step 150 is started. At the time of reproduction, when the turning point approaches, the speaker 7 informs it of the turning point, and the display 5 displays an arrow indicating the direction in which the vehicle should turn and is displayed for a certain period of time or until the car finishes turning.

In steps 109 to 115, data required for display in modes 1 to 6 is constantly calculated, and even if the mote switching is performed, the display corresponding to each mode can be performed immediately in step 116.

Further, depending on each mode, the magnitude of acceleration / deceleration, etc., quiet music, uptempo music, etc. can be played from the speaker 7.

As described above, the acceleration / deceleration of the vehicle and the vehicle speed are detected, and the information required by the occupant is selectively notified.
