Problems solved by technology

Due to the extremely limited internal space of the brake, the brake pedal angle measurement device based on the Hall sensor has high requirements for installation space and additional devices, and cannot be integrated with the brake valve / brake, and it is not easy to combine with the brake valve body Installation and integration have certain limitations
Therefore, the problem existing in the prior art is: the embedded measurement of the vehicle brake pedal rotation angle cannot be realized, which limits the development of miniaturized and integrated measuring devices

Embodiment Construction

[0025] The embedded measurement method for the vehicle brake pedal rotation angle of the present invention obtains the pedal rotation angle by measuring the displacement of the ejector rod within the value range in which the pedal rotation angle and the displacement of the ejector rod have an approximately linear relationship.

[0026] figure 1 Shown is a schematic diagram of the relationship between the displacement of the vehicle brake pedal ejector rod and the pedal angle

[0027] The pedal rotation angle and ejector rod displacement satisfy the following formula:

[0028]

[0029] where k 1 is the fitting coefficient between the ejector rod displacement Δl and the pedal rotation angle γ, λ(θ 0 -γ) for k 1 / D linearity, γ is the pedal rotation angle, Δl is the displacement of the ejector rod, D is the distance from the center of the upper plane of the ejector rod to the center of rotation of the pedal, θ 0 When the pedal is fully reset, the initial value of the inclu...

Abstract

The invention discloses an embedded measuring method for measuring a turn angle of a vehicle brake pedal. The turn angle of the pedal can be obtained by measuring the displacement of a push rod within a value ranges, in an approximately linear relationship, of the turn angle of the pedal and the displacement of the push rod; or the turn angle of the pedal can be obtained by measuring the output voltage of a position sensor capable of reflecting the displacement of the push rod. The embedded measuring method, disclosed in the invention, for measuring the turn angle of the vehicle brake pedal can be used for accurately measuring the turn angle of the vehicle brake pedal in an embedded manner, and can make it convenient to realize miniaturization design and integration of a measuring device.

Description

technical field [0001] The invention belongs to the technical field of vehicle braking devices, in particular to an embedded measurement method for a vehicle brake pedal rotation angle capable of embedded and accurate measurement of the vehicle brake pedal rotation angle. Background technique [0002] Brake pedal angle is an important basis for vehicle dynamics and braking system control. The brake pedal angle signal can be used as the control parameters of the anti-lock brake system (ABS), electronic brake system (EBS), etc. to improve the braking control performance; it can also be used as the control parameters of traditional vehicle engines and new energy vehicle motors , Eliminate power and braking conflicts, improve energy utilization efficiency; it can also be used as a control parameter of the body control unit (BCM) to control the indicator lights related to braking. [0003] Most existing brake pedal rotation angle measuring devices use Hall sensors to directly me...
