The invention provides an upgrading method, device and system for a vehicle-mounted touch chip, and the method comprises the steps: responding to a chip upgrading instruction, and requesting a vehicle-mounted host to send at least one upgrading data packet required by upgrading when determining that the touch chip has a software upgrading demand through checking upgrading detail information carried by the chip upgrading instruction; in response to receiving of the current upgrading data packet, checking verification information of the current upgrading data packet, and caching the current upgrading data packet under the condition that the current upgrading data packet meets a preset requirement to complete caching of each upgrading data packet; and under the condition that the at least one upgrading data packet meets the integrity requirement, the at least one upgrading data packet is sent to the touch chip according to the upgrading protocol requirement of the touch chip, so that the touch chip completes upgrading by burning the received upgrading data packet. Therefore, under the condition that the vehicle-mounted display screen does not need to be disassembled, software upgrading of the touch chip can be achieved, and the upgrading efficiency of the touch chip is improved.

    本申请提供了一种车载触摸芯片的升级方法、装置及系统,响应于芯片升级指令,通过核对芯片升级指令所携带的升级详情信息,在确定触摸芯片具有软件升级需求时,请求车载主机发送升级所需的至少一个升级数据包;响应于当前升级数据包的接收,核对当前升级数据包的校验信息,在当前升级数据包符合预设要求的情况下,缓存当前升级数据包,完成每个升级数据包的缓存;在至少一个升级数据包满足完整性要求的情况下,将至少一个升级数据包按照触摸芯片的升级协议要求发送至触摸芯片,以使触摸芯片通过烧录接收到的升级数据包完成升级。这样,便可以在无需拆卸车载显示屏的情况下,实现触摸芯片的软件升级,以提高触摸芯片升级效率。
