Embodiment 1

[0068] In this embodiment, the steering transmission mechanism is a single front axle structure, and the vehicle has a group of steerable wheels, namely a left front wheel and a right front wheel. In this embodiment, the preset mapping table includes the following data: (A11, D11), (A12, D12), ... (A1j, D1j), ..., (A1m, D1m), where m can be performed according to actual needs value.

[0069] In the first safety warning condition: for example, the actual rotation angle value obtained through calculation is A0, and the speed difference between the left and right wheels is D1, then if it is determined by looking up the table that the values ​​of D1 and D12 are equal, then determine the preset rotation angle corresponding to D1 The value should be A12, then compare A12 with A0 to determine whether the absolute value of the difference between the two exceeds the preset threshold, if so, a safety warning signal will be sent, otherwise no safety warning signal will be sent.

Embodiment 2

[0073] In this embodiment, the steering transmission mechanism is a double front axle structure, and the vehicle has two sets of steerable wheels, that is, the first set of wheels includes a first left front wheel and a first right front wheel, and the second set of wheels includes a second left front wheel. wheel and the second right front wheel. In this embodiment, the preset mapping table corresponding to the first group of wheels includes the following data: (A11, D11), (A12, D12), ... (A1j, D1j), ..., (A1m, D1m), wherein, m can take a value according to actual needs. The preset mapping table corresponding to the second group of wheels contains the following data: (A21, D21), (A22, D22), ... (A2j, D2j), ..., (A2m, D2m), where m can be based on actual needs Take the value.

[0074] In the first safety warning condition: for example, the actual rotation angle value obtained through calculation is A0, the left and right wheel speed difference D1 of the first group of wheels...

Abstract

The invention provides a steering transmission mechanism safety early warning method and system and a vehicle. The method comprises the steps that an actual turning angle value A0 input by a steering wheel and the left wheel speed and the right wheel speed of at least one set of wheels are obtained; according to the left wheel speed and the right wheel speed of the at least one set of wheels, the left and right wheel speed differences D1, D2,..., Dn of the at least one set of wheels are obtained through calculation; according to the speed differences D1, D2,..., Dn of the left wheel and the right wheel, corresponding preset corner values A1, A2,..., An are determined from the preset mapping tables of the wheels of the corresponding groups; respectively the actual rotation angle value A0 is subtracting from the preset rotation angle values A1, A2..., An to obtain delta A1, delta A2..., and delta An; the delta A1, the delta A2,..., and the delta An are compared with corresponding preset threshold values respectively, and a safety early warning signal is sent out when the following conditions are met: any one or more of the delta A1, the delta A2,..., and the delta An exceed the corresponding preset threshold values; or delta A1, delta A2,..., or delta An obtained at a preset number of different moments within a predetermined time period are different. According to the scheme, vehicle faults can be fed back in time.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a steering transmission mechanism safety warning method, system and vehicle, and the vehicles especially refer to trucks, commercial vehicles and intelligent driving vehicles. Background technique [0002] The steering transmission mechanism of light trucks, heavy trucks and passenger cars is basically a multi-link mechanism. If a part is loose, abnormally deformed, or excessively worn, it is very dangerous, and it is very easy to cause serious traffic safety accidents during driving. At present, the reliability of the steering transmission mechanism is improved in terms of mechanical performance and assembly process, but the occurrence of failure cannot be completely avoided. The longer the mileage of the vehicle, the higher the probability of failure. When the steering transmission mechanism fails, it can only be found through the obvious abnormal performance of the ve...
