Embodiment 1

[0089] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0090] A rapid diagnostic method for an unmanned vehicle, comprising the steps of:

[0091] S0, sending an access request command to the on-board module;

[0092] S1. Obtain the operation data of the vehicle-mounted module, judge whether the operation data is abnormal, if so, judge the abnormal type of the vehicle-mounted module according to the operation data, generate and store fault records including the vehicle-mounted module and the abnormal type;

[0093] The vehicle-mounted module includes a brake-by-wire assembly, a steering-by-wire assembly, an accelerator-by-wire assembly, a remote ignition assembly, a vehicle control assembly, and a vehicle communication assembly;

[0094] The operation data of the brake-by-wire assembly includes brake chip fault status bits, brake CPU operation status data, brake Hall sensor data, brake CAN communication feedback data, brake motor current detection data...

Embodiment 2

[0111] Please refer to figure 1 , the second embodiment of the present invention is:

[0112] A rapid diagnosis method for an unmanned vehicle. On the basis of the first embodiment above, step S1 further includes: if the operating data is abnormal, then obtain all sensor parameters in the unmanned vehicle, and obtain possible fault factors according to the sensor parameters ;

[0113] When there is a large deviation between the current GPS trajectory and the actual execution trajectory (beyond the predetermined design of the electronic fence range, such as 3 meters around the current trajectory), the steering feedback data (steering angle), current vehicle speed, current gear position, and current vehicle wire control are obtained. state. First confirm whether the car body is still in the tracking state, then confirm whether the car body is normal, and then confirm whether the implementation of the steering angle is consistent with the command requirements. If not, it can b...

Embodiment 3

[0122] Please refer to figure 2 as well as image 3 , the third embodiment of the present invention is:

[0123] A rapid diagnosis terminal 1 for an unmanned vehicle, comprising a memory 3, a processor 2 and a computer program stored on the memory 3 and operable on the processor 2, when the processor 2 executes the computer program, the first embodiment described above is realized step.

[0124] Such as image 3 As shown, the rapid diagnosis terminal can be regarded as a diagnosis platform, which is connected with the brake-by-wire assembly, steering-by-wire assembly, accelerator-by-wire assembly, remote ignition assembly, vehicle control assembly and The in-vehicle communication assembly is connected and its data is monitored; before the unmanned vehicle is put into application, use the diagnostic platform to check whether the current unmanned vehicle is in good condition by traversing the data of each on-board module, so as to detect the existence of The hidden on-board...

Abstract

The invention discloses a rapid diagnosis method and terminal for an unmanned vehicle. According to the method, operation data of vehicle modules is obtained; judgement is carried out to determine whether the operation data is abnormal or not, if the operation data is abnormal, the abnormal types of the vehicle modules are judged according to the operation data, and fault records comprising the vehicle modules and the abnormal types are generated and stored; and judgement is carried out to determine whether the design parameters of the vehicle modules are reasonable or not according to all thestored fault records. According to the method, the operation data of the vehicle modules is analyzed after being obtained, and judgement is carried out to determine whether the design parameters of the vehicle modules are reasonable or not according to the analysis result, so that the functions of each vehicle module on the current unmanned vehicle can be rapidly diagnosed, and the vehicle modules with hidden dangers can be found in time and then replaced, thereby achieving the functions of rapid deployment, rapid diagnosis and rapid maintenance.

Description

technical field [0001] The invention relates to the field of unmanned vehicles, in particular to a rapid diagnosis method and terminal for unmanned vehicles. Background technique [0002] Unmanned vehicles are the main trend in the future development of the automotive field. Among them, car tracking driving is a way of automatic driving for unmanned vehicles. Tracking driving refers to the automatic tracking driving of a car according to a pre-set route. The existing tracking driving control is to send the route to the vehicle terminal through the platform, and the vehicle terminal controls the accelerator, brake, shift and other operations. In order to ensure that it can adapt to complex environments, such as uninhabited land reconnaissance, back-end supply, dynamic obstacle surviving, and simulation training, etc. At present, unmanned vehicles are generally customized, and the tires, steering assemblies, and brake assemblies used are all customized by wire. Because non-...
