A vehicle transmitting/receiving device that can perform the following has been proposed.

[Problem that the invention seeks to solve]

However, in conventional devices, the code number as unlocking information was fixed for each vehicle, so when manufacturing the device, a code number had to be assigned to each product.
Manufacturing management was troublesome.

In addition, in-vehicle devices related to driving operability, such as door mirrors and seats, are often set at different positions depending on the driver, but conventional devices control the operation of door mirrors and seats based on radio waves transmitted from a transmitter. It was not possible to move it to a suitable position.

The present invention has been made in view of the above-mentioned conventional problems, and can reduce manufacturing management costs and automatically set in-vehicle devices related to driving operability to a state suitable for the driver. An object of the present invention is to provide a transmitting/receiving device for a vehicle.

Operating state storage means 30 that stores the output of the means 28 in association with the driver information of the code number.
Based on the matching result of the first determining means 22, it is determined whether the output of the operating state detecting means 28 and the stored content of the operating state storing means 30 correspond to the driver information, and the determined result is determined. The locking mechanism 34 is driven to unlock based on the determination result of the match between the second determining means 32 which generates a signal according to the signal and the first determining means 22; and a driving means 36 for driving the on-vehicle device 24 until the determination results match,

[Effect]

When the transmitter 10 is set so that the signal from the writing means 18 can be read by the code number reading means 38 and the code number inputting means 14 is operated arbitrarily, unlocking information and the driver are specified according to this operation. A code number including driver information is stored in the code number storage means 16 and is also stored in the code number storage means 40 via the writing means 18 and the code number reading means 38.

At this time, when the storage command means 26 is operated, the detection output of the operating state detecting means 28 is stored in the operating state storing means 30 in association with the driver information.

When a driver holding the transmitter 10 operates the transmitter 10 after the code number is stored in the code number storage means 40, a carrier wave on which the code number is superimposed is transmitted from the transmitter 44. When this number is received by the receiving means 20, the output of the receiving means 420 is transmitted to the first determining means 22.
It is determined whether the unlocking information of the code number output from the receiving means 20 and the unlocking information of the code number stored in the code number storage means 16 match. When the result of this determination is a match, the driving means 36 performs a process of driving the locking mechanism 34 to unlock. On the other hand, when the above-mentioned determination result is determined to be a non-coincidence, the driving means 36 is in a stopped state. When a matching result is obtained from the first determining means 22, the second determining means 32 selects the output of the operating state determining means 18 and the stored content of the operating state storing means 3o that corresponds to the driver information. A determination is made as to whether there is a match. When the result of this discrimination is found to be a mismatch, the driving means 36 performs a process of driving the on-vehicle device 24 until the result of this discrimination becomes a match. That is, the driving of the on-vehicle device 24 is controlled until a state suitable for the driver is reached.
