Problems solved by technology

However, it is inconvenient for the driver to input the destination address through the keyboard operation during the driving process. The driver can read the name of the destination by voice, but the destination name read by the driver may not match the address in the map. name exact match
The in-vehicle navigation system needs to perform fuzzy matching on the name of the destination read out by the voice, so that multiple alternative addresses will be matched, but these alternative addresses do not match the driver's actual destination address with high accuracy, causing the driver The expected navigation route cannot be obtained, which reduces the user experience

Abstract

The invention discloses a navigation method and vehicle-mounted navigation equipment. The method comprises the following steps of: acquiring a historical address information set and a target address;retrieving an address database according to the target address to obtain a real-time address information set; determining a recommended address according to the historical address information set andthe real-time address information set; planning a navigation route according to the recommended address. Real-time address information in a real-time address information set close to a target addressis obtained through preliminary matching according to the target address, the recommended address is determined according to the historical address information set and the real-time address information set, the historical address information in the historical address information set is used to carry out secondary screening on the addresses in the real-time address information set again, the matching accuracy of the recommended address is improved, and error of a navigation route fed back to a driver is avoided. The navigation route is planned according to the recommended address, so that the user can quickly obtain a navigation route with higher accuracy, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of vehicle navigation, in particular to a navigation method and a vehicle navigation device. Background technique [0002] At present, car navigation equipment can retrieve the destination address by recognizing the voice information input by the driver. However, it is inconvenient for the driver to input the destination address through the keyboard operation during the driving process. The driver can read the name of the destination by voice, but the destination name read by the driver may not match the address in the map. The names match exactly. The in-vehicle navigation system needs to perform fuzzy matching on the name of the destination read out by the voice, so that multiple alternative addresses will be matched, but these alternative addresses do not match the driver's actual destination address with high accuracy, causing the driver The expected navigation route cannot be obtained, which...
