Description

Power-on reset method and system of vehicle-mounted controller and vehicle

Technical Field

The invention relates to the technical field of vehicle-mounted controllers, in particular to a power-on reset method and system of a vehicle-mounted controller and a vehicle.

Background

The in-vehicle controller is a special embedded controller used on a vehicle, also called an electronic control unit (Electronic Control Unit, ECU). In order to avoid the exhaustion of the electric quantity in the storage battery when the vehicle is not in operation for a long time, the vehicle-mounted controller needs to enter a closed state after judging that the vehicle does not need to work so as to reduce the energy consumption of the vehicle as much as possible; and when the work is needed, the working state is recovered from the closed state. Accordingly, the switching of the vehicle-mounted controller between the off state and the operating state is referred to as powering up and powering down.

Along with the rapid development of intelligent automobiles, the proportion of various vehicle-mounted controllers with different functions carried by the intelligent automobiles is higher and higher, and most mechanical parts of the traditional automobiles are basically replaced, so that the safety and stability requirements on the vehicle-mounted controllers are higher and higher. The vehicle-mounted controller is good in power-on and running, and high requirements are put on power-on reset of the vehicle-mounted controller.

At present, the internal chip of the traditional vehicle-mounted controller mostly adopts internal RC reset or is directly connected to the MCU for software reset. Because the RC device is provided with untimely discharge, the vehicle-mounted controller is easy to power up and can not reset effectively when power up is frequently carried out, or the equipment is abnormal when power up and power down are continuously carried out. Meanwhile, as no local reset logic exists, if local abnormal reset occurs, the vehicle-mounted controller needs to be reset as a whole, so that other irrelevant functions need to be restarted, and other functions of the vehicle-mounted controller are affected.
