Method for calibrating pedal open degree value, calibrating device and vehicle

Abstract

The embodiment of the invention provides a method for calibrating a pedal open degree value, a calibrating device and a vehicle. The method comprises the following steps that after a vehicle is started, the calibrating device arranged in the vehicle obtains a first open degree value from a memory, wherein the first open degree value is the preset minimum open degree value of a pedal; the calibrating device detects a second open degree value through a sensor of the pedal, wherein the second open degree value is the current minimum open degree value of the pedal; and the calibrating device uses the second open degree value to calibrate the first open degree value. According to the embodiment, when the current minimum open degree value of the pedal is different from the preset minimum open degree value of the pedal, the current open degree value of the pedal can be used for calibrating the preset minimum open degree value of the pedal so that the vehicle is controlled according to the calibrated minimum open degree value; thus the pedal calibration can be automatically performed without artificial participation; and the pedal calibration cost is reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method for calibrating the pedal opening value, a calibrating device and a vehicle. Background technique [0002] After the vehicle has been assembled and rolled off the assembly line, the same pedal, such as the accelerator or brake pedal, may have different minimum values ​​in the same model of vehicle. For example, due to problems such as assembly line assembly, the minimum opening value may be different when the same pedal is installed on different vehicles of the same model. In other words, the minimum opening value of the existing pedal may vary, resulting in differences in the minimum opening value of the accelerator pedal of each vehicle, affecting the control of the vehicle. [0003] In addition, during the use of the vehicle, the pedal may age over time and its minimum value may change, affecting the control of the vehicle. [0004] In the prior art, after the vehicle is ass...

[0005] However, in the prior art, the off-line calibration operation needs to be performed for each off-line vehicle, which requires a large amount of engineering and high cost

And as time goes by, the pedals may age, the minimum value of the vehicle may change, and engineers need to calibrate again, which consumes a lot of labor costs

Otherwise, if the normalization is still performed according to the minimum value detected by the previous engineer in the off-line calibration link, it will lead to inaccurate control of the vehicle and affect the user experience
