Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle information collecting device for collecting information about vehicles.

[0002]

2. Description of the Related Art A conventional vehicle information collecting apparatus uses, for example, an integrated traveling distance, a speed, a pulse output from a traveling sensor each time the vehicle travels a unit distance or a pulse output from an engine rotation sensor each time the vehicle travels. Information such as engine speed and speed over time was collected.

In addition to the above-mentioned information collection, information such as the time when the door is open and the number of people getting off the vehicle at that time are also collected by, for example, a door opening / closing signal or a pulse output every time getting off the vehicle. Was doing. In addition, the collection device has an actual / empty key for inputting whether the vehicle is in the actual vehicle state or in the empty state, and the driving vehicle is in the actual / empty state depending on the state.
The empty vehicle key was operated to input whether the vehicle was in the actual vehicle state or in the empty vehicle state.

[0004]

As described above, in the conventional vehicle information collecting device, the driver operates the actual / empty vehicle key to input the actual vehicle state or the empty vehicle state. For this reason, the burden of operating the actual / empty key is increased, and mistakes in operation and forgetting of input also occur, thus reducing the reliability of the collected information.

It is an object of the present invention to provide an improved vehicle information collecting device which eliminates a driver's burden and can collect accurate data in an actual vehicle or an empty vehicle.

[0006]

Means adopted by the present invention to solve the above problems will be described with reference to FIG.
FIG. 1 is a basic configuration diagram of the present invention. In a vehicle information collecting device that collects vehicle information based on signals input from a running sensor, an engine rotation sensor, and a plurality of external input channels, a weight sensor (1) for measuring the weight of the vehicle.
And an actual / empty determining means (2) for determining whether the vehicle is in an actual vehicle state or an empty vehicle state based on the weight value output from the weight sensor (1), and the actual / empty determining means (2). And an actual / empty recording means (3) for recording the fact that the vehicle is in an actual state or in an empty state.

The determination of the actual vehicle or the empty vehicle state by the actual / empty determining means (2) and the recording by the actual / empty recording means (3) are performed by the actual / empty vehicle key for inputting the actual vehicle or the empty vehicle state. It works only when is not input. When the actual / empty determination means (2) determines that the actual / empty vehicle key is set to an empty vehicle, and when the actual / empty vehicle key is set to the actual vehicle, An alarm is issued when the empty determination means (2) determines that the vehicle is empty.

The determination by the actual / empty determining means (2) and the recording by the actual / empty recording means (3) are performed each time there is a state change input of the vehicle.

[0009]

The actual / empty determining means 2 determines that the vehicle is in the actual vehicle state when the weight value of the vehicle output from the weight sensor 1 exceeds a certain set value, and the actual / empty recording means 3 indicates the actual vehicle state. When it is less than a certain set value, it is determined that the vehicle is empty, and the actual / empty recording means 3 records that the vehicle is empty.

When the actual vehicle or the empty vehicle state is input by the actual vehicle / empty vehicle key for inputting the actual vehicle state or the empty vehicle state, the input state is input to the actual / empty recording means 3, but the actual vehicle / empty vehicle state is input. When neither state is input from the key, the actual / empty judging means 2 operates to record the actual vehicle or empty vehicle state in the actual / empty recording means 3.

Further, when the vacant vehicle state is input by the actual / empty vehicle key, or when the actual / empty determining means 2 determines the actual vehicle state, an alarm is issued. Also, when the actual / empty vehicle key is input with the actual / empty vehicle key, an alarm is issued when the actual / empty determining means 2 determines that the actual / empty vehicle state is empty. Further, the determination of the actual vehicle or the empty vehicle state by the actual / empty determination means 2 and the recording in the actual / empty recording means 3 are performed each time there is a state change input of the vehicle.

As described above, the weight of the vehicle is measured, and whether the vehicle is in the actual vehicle state or in the empty vehicle state is determined and recorded. Therefore, the determination is automatically made without any human intervention, and the determination is made. Since the vehicle data can be collected using the recorded data, the reliability of the collected information can be improved.

Further, since the actual / empty determination is made by using the measured value from the weight sensor only when neither the actual vehicle state nor the empty vehicle state is input from the actual / empty vehicle key. Accurate information can be collected even if input is forgotten. Also, when an actual vehicle or empty vehicle state is entered with the actual / empty vehicle key, an alarm is issued if the actual vehicle or empty vehicle state is different from the actual vehicle or empty vehicle state determined using the measured value from the weight sensor. You can enter the correction by knowing.

Further, since the actual / empty judgment and the recording of the judgment result are made to operate every time the change of the vehicle state is inputted, the operation load can be lightened.
