A side slip detection device and method

Abstract

The invention discloses a sideslip detection device and method. According to the method, the device is used for measuring the sideslip amount of a double-steering shaft-type vehicle. The sideslip detection device comprises a first measuring plate (CL1), a second measuring plate (CL2), a first sideslip measuring sensor (CG1) and a second sideslip measuring sensor (CG2). The first measuring plate (CL1) is arranged on the left side and used for detecting the sideslip amount of a left steering wheel of the vehicle, the second measuring plate (CL2) is arranged on the right side and used for detecting the sideslip amount of a right steering wheel of the vehicle, the first sideslip measuring sensor (CG1) is related to the first measuring plate (CL1) and used for converting the sideslip amount measured by the first measuring plate (CL1) into electric signals, the second sideslip measuring sensor (CG2) is related to the second measuring plate (CL2) and used for converting the sideslip amount measured by the second measuring plate (CL2) into electric signals, and the first measuring plate (CL1) and the second measuring plate (CL2) are arranged in the front-and-rear direction in a staggered mode. Thus, by using the sideslip detection device, the sideslip amount of the left steering wheel and the sideslip amount of the right steering wheel can be detected sequentially, the left steering wheel and the right steering wheel pass through the first measuring plate (CL1) and the second measuring plate (CL2) sequentially, accordingly, mutual influence between the left steering wheel and the right steering wheel during measurement can be avoided or reduced, and measuring accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to the technical field of automobile testing, and more particularly to a device and method for detecting lateral sideslip of steering wheels. Background technique [0002] The lateral side slip of the steering wheel refers to the lateral slippage of the tire relative to the ground at the ground contact point of the steering wheel tire during the straight-line driving of the car. The lateral slip of the steering wheel is caused by the unreasonable matching of the steering wheel positioning parameters, especially the toe angle and camber angle of the steering wheel. When the toe angle is too large relative to the camber angle, the wheel will slip to the outside; if the toe angle is too small relative to the camber angle, the wheel will slip to the inside; only when the two are well matched, the wheel will not produce sideways to slip. The amount of lateral sideslip is evaluated ...

Problems solved by technology

[0006] The inventor of this patent has found through research that for vehicles with dual steering shafts, there are the following problems in using a single-board side slide table to measure the lateral slip of the steering wheel: using a single-board measurement, only the side of the wheel on one side of the motor vehicle can be measured. Slip, the side slip of the other wheel cannot be measured, and the vehicle must be driven directly against the measuring board, otherwise the measurement error caused by the vehicle being incorrect will be superimposed or subtracted from the real value of the side slip, resulting in a measurement value error big problem
