Abstract
A vehicle travel locus transmission system to be mounted on a vehicle includes a GNSS receiver, a vehicle-side transceiver, a locator processor, a wheel speed sensor, a gyro sensor, and an acceleration rate sensor. The locator processor generates, on predetermined cycles, a latest first linear coordinate as a linear function parameter that couples latest first positional coordinates and second positional coordinates on a previous cycle. The first and second positional coordinates are to be acquired on the basis of a positioning signal received by the GNSS receiver. On the condition that an angle formed by the first linear coordinate with an extension of a second linear coordinate generated on the previous cycle exceeds a predetermined threshold, the locator processor sends data regarding the first linear coordinate together with vehicle identification data, from the vehicle-side transceiver to an external device.
