The embodiment of the invention relates to a vehicle control method and device, equipment and a medium, and the method comprises the steps: receiving a vehicle control instruction sent by a terminal and a to-be-compared first comparison key after a vehicle and the terminal are in a preset target distance and are successfully connected according to a preset communication mode; the TBOX compares the first comparison key with a stored comparison key, generates a random number after successful comparison and sends the random number to the terminal, and the terminal verifies the random number and sends a comparison verification success result to the TBOX; and the TBOX processes the vehicle control instruction based on a preset decryption algorithm to obtain a target control instruction and sends the target control instruction to a vehicle body domain controller of the vehicle, and the TBOX receives a processing result fed back by the vehicle body domain controller and sends the processing result to the terminal. Therefore, the TBOX can serve as a role of a communication part of a digital key system, the cost of the whole vehicle is reduced, meanwhile, the safety of the vehicle is improved in the communication connection pairing authentication and digital key vehicle control process, and the risk that the digital key is attacked by a relay is reduced.
本公开实施例涉及一种车辆控制方法、装置、设备及介质,其中方法包括:当车辆与终端在预设的目标距离内,按照预设的通信方式建立连接成功后,接收终端发送的车辆控制指令和待对比的第一对比钥匙;TBOX将第一对比钥匙和存储的对比钥匙进行对比,在对比成功后生成随机数发送给终端,终端对随机数进行验证后将比对校验成功结果发送给TBOX;TBOX基于预设的解密算法对车辆控制指令进行处理得到目标控制指令发送给车辆的车身域控制器,TBOX接收车身域控制器反馈的处理结果发送至终端。由此,TBOX可以作为数字钥匙系统通信部分的角色,减少了整车成本,同时在通信连接配对认证及数字钥匙控车过程中提高了车辆的安全性降低了数字钥匙被中继攻击的风险。
