The invention discloses a vehicle state inspection system and method before OTA upgrade, and belongs to the technical field of automotive electronics. The system comprises a vehicle-mounted audio entertainment system, a vehicle-mounted remote communication terminal, a gateway, an automatic gearbox control system, a vehicle body electronic stabilization system, a vehicle body control module and a battery management system. The vehicle-mounted remote communication terminal receives a P-gear signal sent by the automatic gearbox control system, an EPB signal of the vehicle body electronic stabilization system, an anti-theft signal of the vehicle body control module and an electric quantity signal of the battery management system; and the state of the current vehicle is judged according to the P-gear signal, the EPB signal, the anti-theft signal and the electric quantity signal, when the electric quantity signal, the P-gear signal, the EPB signal and the anti-theft signal meet set conditions in sequence, OTA upgrading is carried out, and if the set conditions are not met, OTA upgrading is stopped, and the signals are transmitted to a vehicle-mounted audio entertainment system to be displayed. The vehicle state can be checked before OTA upgrading, and the reliability and safety of upgrading are improved.
本发明公开了一种OTA升级前的车辆状态检查系统及方法,属于汽车电子技术领域,包括车载音响娱乐系统、车载远程通信终端、网关、自动变速箱控制系统、车身电子稳定系统、车身控制模块及电池管理系统,车载远程通信终端接收自动变速箱控制系统发送的P挡信号、车身电子稳定系统的EPB信号、车身控制模块的防盗信号及电池管理系统的电量信号;根据P挡信号、EPB信号、防盗信号及电量信号判断当前车辆的状态,当电量信号、P挡信号、EPB信号及防盗信号依次均满足设定的条件时,进行OTA升级,若不满足,则停止OTA升级,并将这些信号传送给车载音响娱乐系统进行显示,可以在OTA升级前对车辆状态进行检查,提高升级的可靠性和安全性。
