The invention relates to a combination instrument and a vehicle. The combination instrument comprises a combination instrument assembly and a low-speed driving reminding assembly. The combination instrument assembly comprises a CAN transceiver and a combination instrument processor. The combination instrument processor is connected with the CAN transceiver, and the CAN transceiver is connected with a vehicle CAN bus. The combination instrument processor acquires vehicle driving information transmitted on the vehicle CAN bus through the CAN transceiver; the combination instrument processor is used for judging whether the vehicle is in a low-speed driving state or not according to the vehicle driving information and generating a low-speed reminding instruction when a judgment result is yes;and the low-speed driving reminding assembly is connected with the combination instrument processor and used for outputting an alarm sound signal according to the low-speed reminding instruction. Thecombination instrument and the low-speed driving reminding device share the processor, the CAN transceiver and a PCB, an integration degree is greatly improved, product weight is decreased, a productsize is reduced, product cost is decreased, light weight of the whole vehicle is facilitated, and arrangement of the whole vehicle is facilitated too.
本发明涉及一种组合仪表及车辆,该组合仪表包括组合仪表组件和低速行驶提醒组件。组合仪表组件包括CAN收发器和组合仪表处理器,组合仪表处理器与CAN收发器连接,CAN收发器与车辆CAN总线连接。组合仪表处理器通过CAN收发器获取车辆CAN总线上传输的车辆行驶信息;组合仪表处理器用于根据车辆行驶信息判断车辆是否处于低速行驶状态,并在判断的结果为是时生成低速提醒指令;低速行驶提醒组件与组合仪表处理器连接,用于根据低速提醒指令输出报警声音信号。本发明实现了组合仪表与低速行驶提醒装置共用处理器、CAN收发器以及PCB板,集成化程度大大提高,减小了产品重量、缩小了产品体积、降低了产品成本,有利于整车轻量化、易于整车布置。
