Abstract

The invention aims to provide a vehicle-mounted navigation quick starting method. Signals passing through the door opening sensor are transmitted to the BCM module; the BCM module sends a door openinglevel signal to a navigation main control MCU; then the navigation is in a dormant state and power-on state detection is carried out; then the navigation enters the vehicle to power on the vehicle; finally, the main control MCU detects a power-on state, starts the navigation, thus, navigation can be started quickly. According to the technical scheme, the navigation can enter the dormant state inadvance before the vehicle is powered on and ignited, after a user carries out power-on ignition operation, starting awakening can be triggered, the navigation can be started rapidly, the purpose of rapid starting of the vehicle-mounted navigation can be achieved within 3S, and therefore the requirement of a terminal user for the rapid starting speed is met.

Description

technical field [0001] The invention relates to the field of vehicle-mounted navigation, in particular to a method for quickly starting the vehicle-mounted navigation. Background technique [0002] With the popularization of Android system in terminal equipment, the application of Android operating system in car navigation is becoming more and more extensive. Boot speed requirements. In order to enable the car navigation system to quickly start the system after power-on and ignition, a reliable hardware wake-up method is added when designing the system solution. Contents of the invention [0003] In order to solve the above problems, the present invention provides a quick startup method for vehicle navigation. The signal of the door open sensor is transmitted to the BCM module, and the BCM module sends the door open level signal to the main control MCU of the navigation. After that, the navigation is in a dormant state and is powered on. Status detection, and then used t...
