In-vehicle device, information processing device, sensor data transmission method, and information processing method

Abstract

An in-vehicle device according to the present disclosure includes a processor, and a memory. The memory having instructions that, when executed by the processor, cause the processor to perform operations: acquiring vehicle state information indicating a state of a vehicle, and sensor data measured by a sensor provided on the vehicle, compressing the sensor data at a compression rate varying depending on the vehicle state information, and transmitting the compression rate in association with the compressed sensor data. The vehicle state information includes at least vehicle speed of the vehicle. The compression rate is a value determined according to whether the vehicle speed is higher than a first threshold.
