Motor speed signal processing system for vehicle, control method thereof and vehicle

Abstract

The invention discloses a motor speed signal processing system for a vehicle, a control method thereof and a vehicle. The system comprises a first controller and a second controller; the first controller and the second controller are respectively used for collecting motor speed signals and performing check, wherein the first controller generates a first rotational speed when the check is passed, and determines the motor speed according to the first rotational speed when the check of the second controller fails; the second controller generates a second rotational speed when the check is passed,and determines the motor speed according to the second rotational speed when the check of the first controller fails; when the check of both the first controller and the second controller is passed,the motor speed is also determined according to the first rotational speed and the second rotational speed. The system obtains the motor speed through two controllers, thereby improving the accuracy of the motor speed, and can use the other controller to collect and process the speed signal when an exception occurs to one controller, thereby ensuring the effectiveness of the motor speed and further guaranteeing the safety of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a vehicle motor speed signal processing system, a vehicle, a control method of the vehicle motor speed signal processing system and a non-transitory computer-readable storage medium. Background technique [0002] At present, the collection of the motor speed signal by the vehicle is mostly based on a controller, that is, an ADC (Analog-to-Digital Converter, analog-to-digital converter) of a controller is used to collect the motor speed signal. [0003] The fault tolerance of the above method is poor, that is, if the controller has problems such as calculation errors, system failures, or deadlocks, or there is strong interference in the signal transmission process that causes signal transmission errors, the controller will not be able to accurately obtain the motor speed. , affecting driving safety. Contents of the invention [0004] The present invention aims to so...
