Embodiment Construction

[0034] like image 3 As shown, the navigation system provided by the present invention includes: navigation hardware for sending the collected navigation data to the MCU; MCU for reading and temporarily storing the navigation data sent by the navigation hardware. , sending the navigation data to the vehicle-mounted computer; the vehicle-mounted computer is used to receive the navigation data sent by the MCU, and complete the navigation application of the navigation data. By adding the navigation data sent by the navigation hardware to read and temporarily store, when the on-board computer is started, the navigation data is sent to the MCU of the on-board computer. After the system is powered on, the MCU starts instantly, and the reading of the MCU And the function of caching navigation data to realize the reading of navigation data when the navigation system is started. And the MCU is connected to the CPU of the on-board computer, and the navigation data is directly sent to t...

Abstract

The invention relates to the field of navigation and provides a navigation system and a navigation method. The navigation system comprises navigation hardware, a micro controller unit (MCU) and a vehicle-mounted computer. The navigation hardware is used for transmitting collected navigation data to the MCU. The MCU is used for reading and temporarily storing the navigation data transmitted by the navigation hardware. When the vehicle-mounted computer is powered on, the MCU transmits the navigation data to the vehicle-mounted computer. The vehicle-mounted computer is used for receiving the navigation data sent by the MCU and finishing navigation application of the navigation data. Due to the fact that the MCU is added to the navigation system, when the system is powered on, the MCU is instantly powered on, and the MCU reads and temporarily stores the navigation data, and thereby the navigation data is immediately read when the navigation system starts. Due to the fact that the MCU is connected with a central processing unit (CPU) of the vehicle-mounted computer, the navigation data is directly sent to a hardware abstraction layer of an operating system, and thereby reading of the navigation data does not contact with a kernel space of the operating system, the navigation data is obtained through a user space and application is expanded.

Description

technical field [0001] The invention belongs to the field of navigation, in particular to a navigation method and a navigation system. Background technique [0002] At present, the navigation under the Android system is based on the software and hardware framework. The navigation hardware is connected to the vehicle-mounted computer. The vehicle-mounted computer carries the Android system. The navigation method of data under the Android system, such as figure 1 shown. For navigation data adaptation under the Android system, it is necessary to wait for the Android system to start completely after power-on before reading the navigation data, and the startup of the Android system takes a certain amount of time. The Android system navigation data adaptation must read the navigation data from the kernel space of the operating system, thus limiting the application of the Android system. [0003] To sum up, the current navigation system has the disadvantages of reading navigatio...
