Method and apparatus for starting a vehicle, vehicle, and computer-readable storage medium

Abstract

The invention provides a method and apparatus for starting a vehicle, vehicle, and computer-readable storage medium. The starting method of the vehicle comprises the following steps: when the vehiclemeets a preset starting condition, sending an authentication request to a battery management system; when the vehicle meets a preset starting condition, sending an authentication request to a batterymanagement system. When the random number sent by the battery management system is received within the first preset time after the authentication request is sent, the random number is calculated according to the first preset encryption algorithm and the first calculation result is obtained. A first calculation result is sent to the battery management system; when the authentication passing information sent by the battery management system is received within the second preset time period after the first calculation result is sent, an authentication success flag bit for controlling the high voltage power-up of the battery management system is sent to the battery management system. The keyless entry startup system of the embodiment of the invention authenticates with the battery management system according to the random number and the preset encryption algorithm, and has high security because the preset encryption algorithm will not be transmitted on the CAN bus.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle starting method, a device, a vehicle and a computer-readable storage medium. Background technique [0002] In related technologies, in order to improve user experience, the vehicle is equipped with a keyless entry and start system, through authentication between the keyless entry system and the working system controller, so that the user can open the door and start the vehicle without using a key. [0003] However, since the authentication between the keyless entry system and the working system controller often uses a key for authentication, the key may be stolen when it is transmitted on the CAN bus, so that the controller after replacing the working system controller without permission It can work normally through the stolen key, so that the anti-theft performance of the vehicle is poor, and there are potential safety hazards. Contents of the invention [0004]...
