Abstract

The invention discloses a CPU fault processing method, a vehicle and a readable storage medium. The method comprises the steps: controlling a main CPU and an auxiliary CPU to carry out the detection through a preset mode in a vehicle driving process, so as to judge whether the main CPU and the auxiliary CPU have faults or not; if the auxiliary CPU has a fault and the function of the main CPU is normal, a first control signal value is used as an output signal value, and the first control signal value is obtained through operation of an input signal value generated when the main CPU obtains a driver to control the vehicle; if the main CPU has a fault and the function of the auxiliary CPU is normal, a second control signal value is used as an output signal value, and the second control signal value is obtained by the auxiliary CPU through obtaining the input signal value and carrying out operation; and controlling a corresponding functional module in the vehicle according to the output signal value. According to the invention, the vehicle control safety of the vehicle CPU is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control system fault handling, in particular to a CPU fault handling method, a vehicle and a readable storage medium. Background technique [0002] The controller of the car includes controllers such as vehicle control, brake control, body control, air conditioner, and instrument; The reliability of the device determines the safety of the vehicle. Therefore, the importance of the vehicle CPU (Central Processing Unit, Central Processing Unit) for the vehicle is becoming more and more significant, and the performance requirements for the vehicle CPU are also getting higher and higher. [0003] In order to improve the stability of the CPU, the control method usually used at present is that only the main CPU outputs control information to the outside world, and the sub CPU is completely in a standby state, and does not output control signals to the outside. A watchdog is also set up to monitor the ma...
