Embodiment Construction

[0065] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0066] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0067] refer to figure 1 , shows a flow chart of the steps of an embodiment of a vehicle fault detection method of the present invention, the method may specifically include the following steps:

[0068] Step 101, when the vehicle is abnormal, the output signal of the brake light switch is acquired.

[0069] Wherein, the output signal of the brake light switch includes a vehicle body controller signal and a vehicle controller signal. The brake light switch is respectively connected to the body controller and the vehicle controller through two hard wire signals, and the actual state of the brake light switch is sent to the body controller and the vehicle controller. The body controller...

Abstract

A method and device for detecting a fault in a vehicle, and a vehicle. The method comprises: when a vehicle experiences an abnormality, acquiring output signals of a brake lamp switch, the output signals of the brake lamp switch including a body control module signal and a vehicle control unit signal; determining whether the output signals of the brake lamp switch satisfy a preset abnormal condition; if the output signals of the brake lamp switch satisfy the abnormal condition, acquiring location information to determine whether an operation fault occurs in the vehicle, the location information comprising location information of a braking pedal and location information of a throttle pedal; and if no operation fault is found in the vehicle, determining a fault of the vehicle according to pressure information of a master cylinder, the output signals of the brake lamp switch and target location information. The invention simplifies a troubleshooting operation for a vehicle, thereby enhancing fault detection efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle fault detection method, device and vehicle. Background technique [0002] At present, the brake light switch on the vehicle is to provide braking signals for each unit of the vehicle. When the vehicle's control system is abnormally matched, the vehicle will experience problems such as weak acceleration, cruise failure, and abnormal lighting of the brake light. [0003] In the prior art, when troubleshooting the above-mentioned faults of the vehicle, the inspectors of the vehicle cannot obtain accurate judgment based on the real-time vehicle condition data when the vehicle breaks down, so it is difficult to distinguish whether the fault of the vehicle is the damage of the brake light switch itself or the fault of the vehicle. The problem of abnormal matching of the control system. Therefore, the existing fault is usually solved by directly replacing the brake light swi...
