NAVIGATION DEVICE, AND NAVIGATION METHOD

A navigation apparatus and a navigation method are disclosed. The navigation apparatus (100) includes a main processor (110), a coprocessor (120), a locator (130), and a first memory (140). The main processor (110) is configured to: generate navigation data, store the navigation data in the first memory (140), and enter a sleep state after storing the navigation data. The locator (130) is configured to determine a current location of the navigation apparatus (100). The coprocessor (120) is configured to: obtain the navigation data stored in the first memory (140), and perform navigation according to the navigation data and the current location of the navigation apparatus (100) determined by the locator (130). The performing navigation includes at least one of the following: triggering the main processor (110) to update the navigation data, triggering voice broadcast, or determining data that needs to be displayed in the navigation data. Power of the main processor (110) is higher than power of the coprocessor (120). Therefore, sleeping of the main processor (110) while the coprocessor (120) performs navigation can reduce power consumption of the navigation apparatus (100) and improve a battery life of the navigation apparatus (100).
