Abstract

The invention discloses an instrument software upgrading method and device and a storage medium. The method comprises the steps that whether the vehicle type of a current to-be-upgraded vehicle is a vehicle type without central control or not is judged; when the vehicle type of the current to-be-upgraded vehicle is a vehicle type without central control, the instrument enables an instrument USB interface to be in direct current external connection with a USB storage device through an external connection wire, and an instrument upgrading package is obtained through the USB storage device to achieve software upgrading; when the vehicle type of the current to-be-upgraded vehicle is a central control vehicle type, the instrument connects an instrument USB interface with a central controller through an external connection wire, the central controller is connected with a USB storage device through an external connection wire, and the central controller is connected with a cloud server through a communication control unit; an instrument upgrade package is obtained through the USB storage device or the communication control unit to achieve software upgrade; software updating can be conveniently and efficiently completed, the updating cost is reduced, the updating time is shortened, the actual requirement is met, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle instrument upgrades, in particular to an instrument software upgrade method, equipment and storage medium. Background technique [0002] With the development of on-board chip technology and LCD screen technology, full LCD instruments have emerged; full LCD instruments are widely used in more and more car models because of their good display effect, personalized customization, and generalization. Become the future development trend of the instrument. [0003] Because the full LCD instrument software includes the operating system and a large number of pictures, the data packets are often dozens or even hundreds of MB; while the existing vehicle controller area network (Controller Area Network, CAN) network transmission rate is only about a dozen KB per second , used for full LCD instrument software upgrade speed is slow, experience is poor, and operation is inconvenient. [0004] In order to solve...
