Vehicle resource control method based on interconnection between mobile terminal and vehicle system

Abstract

The invention discloses a vehicle-mounted resource control method based on interconnection of a mobile terminal and a vehicle-mounted system. The mobile terminal is connected with the vehicle-mounted system through a central control platform, control instructions from the vehicle-mounted system and the mobile terminal are forwarded to a memorizer to be cached through the central control platform in the vehicle-mounted resource control method, the control instructions corresponding to all vehicle-mounted resources are determined, for any vehicle-mounted resource, the control instruction corresponding to the vehicle-mounted resource is classified according to the source and the operation type, and operation instructions to be executed are determined according to the priorities of the operation instructions of different types and are executed. By means of the vehicle-mounted resource control method, the problem that conflicts occur when the mobile terminal and the vehicle-mounted system control the same vehicle-mounted resource at the same time is effectively solved, the received control instructions are cached and then accumulated in the vehicle-mounted resource control method and then processed in batches, the access frequency of a CAN bus is lowered, and the operation frequency of an ECU controller is lowered.

Description

technical field [0001] The invention relates to the field of intelligent vehicle-mounted systems, in particular to a vehicle-mounted resource control method based on the interconnection between a mobile terminal and a vehicle-mounted system. Background technique [0002] The vehicle-mounted system is an automotive electronic device that uses technologies such as embedded computers, satellite positioning, communication, and control to provide safety, environmental protection, and comfort functions and services. It is an integral part of smart cars. Existing vehicle systems include: center console with liquid crystal display and touch screen (running operating system, providing hardware memory, WIFI or Bluetooth interface and CAN interface), CAN bus, each ECU controller (Electronic ControlUnit), central control The console and the ECU controller are connected to each other through the CAN bus, and the control commands sent by the center console are transmitted to the ECU contr...
