Problems solved by technology

However, in the car dynamic driving simulator, the carrier (dynamic cockpit) of the measured object (pedal, handbrake lever, gear lever) is a moving carrier relative to the earth reference system. At this time, the three-axis sensor of the measured object detects The signal includes not only the attitude change signal of the measured object relative to the carrier, but also the inertial acceleration signals such as the attitude change of the carrier relative to the earth reference system and its own vibration. Therefore, the signal detected by the MEMS sensor cannot correctly reflect the relative position of the measured object. The attitude of the carrier changes, which limits its application

Embodiment 1

[0044] Embodiment 1: Taking the extraction of the single-axis inclination signal of the pedal of the car driving simulator as an example

[0045] Usually pedal signals include: clutch pedal, brake pedal, accelerator pedal signals, their signal acquisition methods are similar, when detecting the pedal rotation angle, the change angle of the pedal can be detected through the change of one axis of the three-axis acceleration sensor, generally choose X axis or Y axis as the sensitive axis. Figure 4 A schematic diagram of the installation of the dynamic inclination detection device taking pedal inclination angle detection as an example is shown. During the installation, fix the two sensor probes on the pedal transmission mechanism and the adjacent static parts of the car body in a surface-mounted manner. The distance between the two sensor probes should be as close as possible to reduce the difference in the moment of inertia of the carrier when the carrier moves. impact on preci...

Embodiment 2

[0047] Embodiment 2: Taking the extraction of the three-axis taper signal of the gear position of the car driving simulator as an example

[0048] Figure 5 It shows the position where the acceleration sensor is installed on the gear lever of the car; the detection of the gear position signal is different from the detection of the pedal. The detection of the gear position needs to measure the three axial directions of the three-axis acceleration sensor when the gear lever is in each gear position. Output the inclination angle, and record this data in the RAM memory. When the gear position changes, the microprocessor collects two groups of detection signals of the three-axis acceleration sensor on the gear lever and on the surface of an object that is in a static state relative to the vehicle body. X1, Y1, Z1 and X2, Y2, Z2, through signal conditioning, acquisition, AD conversion, digital filtering and algorithm processing, shield the common mode signals such as vibration, mome...

Abstract

The invention discloses a dynamic inclination detecting device for an automotive dynamic driving simulator, which comprises two acceleration transducers, a signal conditioning circuit, a microcontroller, a data processing module, a communication circuit and an upper computer. The invention discloses a detecting method using the dynamic inclination detecting device, which is characterized in that probes of the two transducers are arranged on a detected object and a movement carrier of the detected object in the same posture respectively, and the arranging positions are as close as possible so that the two transducers are approximately positioned in one rigid body. Meanwhile, three-dimensional acceleration signals on the detected object and the carrier are extracted; data fusion and processing are performed on the two groups of signals to remove common-mode signals of common vibration, rotational inertia, posture change and the like; and the different-mode signals of the taper angle change of the relative movement carrier of the detected object are reserved so as to acquire the angle variable of the relative carrier of the detected object. The device and the method are used for detecting the angle or the taper in the dynamic carrier, and expand the application range of the acceleration transducers.
