Solution Overview

Problem

Existing vehicle control systems do not consider the attributes of both the user and the package when performing air conditioning control during mixed transportation of passengers and freight.

Innovation Solution

A vehicle control system that acquires and considers the attributes of both the user and the package to perform targeted air conditioning control, including controlling airflow and using physical barriers to minimize the impact of package attributes on the user.

1Adaptability or versatility

If air conditioning control considers both user and package attributes, then comprehensive protection is improved, but system complexity increases

Solution Approach 1:

The patent applies preliminary action by acquiring and storing attribute information about the user and package before the air conditioning control is actually needed. The control device receives attribute data in advance, determines their locations, and prepares control instructions based on this pre-acquired information. This allows the system to handle complex multi-attribute considerations without increasing operational complexity, as the decision-making data is collected beforehand rather than requiring real-time complex analysis during temperature control operations.

AI summary

A vehicle control device is used for a vehicle that simultaneously transports a user and a package. The vehicle control device includes a controller configured to: acquire an attribute of the user and an attribute of the package; determine whether the user and the package are loaded in the vehicle; and upon determining that the user and the package are loaded in the vehicle, perform air conditioning control according to the attribute of the user and the attribute of the package.
