Embodiment Construction

[0031] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0032] The term "computer equipment" in this context, also referred to as "computer", refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, which may include a processor and The memory is implemented by the proces...

Abstract

The invention belongs to the field of vehicle-mounted electronics, and provides a vehicle-mounted navigation rapid drive method and device based on dual systems. The method includes the following steps that an air conditioner operation virtual key is generated for a vehicle-mounted electronic device through an RS232 device and the air conditioner information in an ECU of a vehicle, and the virtual key is displayed on a touch display screen; a control command input by a user is received and converted into a CAN bus command, and the CAN bus command is sent to the ECU of the vehicle so that an air conditioner can be controlled. According to the technical scheme, the method has the advantage of being high in user experience degree.

Description

technical field [0001] The invention relates to the field of electronic vehicles, in particular to a dual-system-based fast driving method and device for vehicle navigation. Background technique [0002] Car navigation system, its built-in GPS antenna will receive the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the car navigator, the position coordinates determined by GPS satellite signals Matching with this, to determine the exact position of the car in the electronic map, this is what is usually called the positioning function. On the basis of positioning, the multi-function monitor can provide the best driving route, road conditions ahead, and the nearest gas station, restaurant, hotel and other information. If unfortunately the GPS signal is interrupted and you get lost because of this, don't worry, the GPS has recorded your driving route, and you can return on the same road. Of course...
