Abstract

The invention relates to a method and device for pedal fault diagnosis of a vehicle, and the method specifically comprises the steps: detecting whether a driving seat is in an unmanned state or not, collecting the actual null voltage of a pedal under the condition that the driving seat is in the unmanned state, and determining whether the pedal has a null fault or not according to the actual nullvoltage. The device may update a set value of the null voltage in the vehicle controller based on an actual null voltage when the driver seat is in an unmanned state. The method can be applied to thefield of auxiliary driving and automatic driving, and the safety of vehicle control is improved through the actual null voltage when the driving seat is in the unmanned state.

Description

technical field [0001] The present application relates to the technical field of vehicle electronics, in particular to a pedal fault diagnosis method and device. Background technique [0002] Intelligent driving technology requires real-time monitoring of vehicle operating conditions, such as vehicle speed monitoring and pedal zero fault detection. Among them, the pedal zero fault includes zero offset fault. Zero offset fault refers to the deviation between the initial zero position and the actual zero position of the vehicle pedal (such as accelerator pedal, brake pedal, etc.) caused by reasons such as long-term aging and wear, and the vehicle control program or software is usually based on The initial zero position of the vehicle pedal is used as a reference to control the vehicle, and the control basis does not match the actual zero position, which leads to certain safety hazards in vehicle control. [0003] Existing zero-position fault detection usually includes the fo...
