Abstract

To reduce the man-hours of software development when vehicle types are deployed, an in-vehicle equipment control device has a control unit that outputs, to actuators, control signals based on the outputs from sensor devices. The control unit includes a middleware layer and a device driver layer as software components. The middleware layer includes a routing module that selects whether the communication data output from the sensor devices is output as is or the communication data is subjected to predetermined processing and then output according to the type of the communication data, and a treatment module that performs the predetermined processing on the communication data. The routing module has a function of outputting the communication data to the device driver.
