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] Example 1: Take the extraction of the single-axis inclination signal of the pedal of a 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 three-axis acceleration sensor can be used to detect the change of the pedal in one axis, generally select X The axis or Y axis is used as the sensitive axis. Fig. 4 shows a schematic diagram of the installation of the dynamic tilt angle detection device taking the detection of the pedal tilt angle as an example. During installation, fix the two sensor probes on the pedal transmission mechanism and the adjacent stationary part of the car body in a surface mount method. The distance between the two sensor probes should be as close as possible to reduce the different moments of inertia when the carrier moves. The impact of accuracy. It should be ensured that the sensitiv...

Embodiment 2

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

[0048] Figure 5 shows the position where the acceleration sensor is installed on the gear lever of the car; the detection of the gear signal is different from the pedal detection. The detection of the gear needs to measure the three axis of the three-axis acceleration sensor when the gear lever is in each gear. The output value of the inclination angle of the direction, and records this data in the RAM memory. When the gear changes, the microprocessor collects the two sets of three-axis acceleration sensors on the gear lever and on the surface of an object that is stationary relative to the car body The detection signals X1, Y1, Z1 and X2, Y2, Z2 are processed by signal conditioning, acquisition, AD conversion, digital filtering and algorithm processing to shield the common mode signals such as vibration, moment of inertia and attitude change shared by the two ...

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.

Description

Technical field [0001] The invention relates to a detection device for measuring angle or taper and a detection method thereof, in particular to a detection device for measuring the angle of a pedal mechanism or a handbrake mechanism or the taper of a gear mechanism used in an automobile dynamic driving simulator and Its detection method. Background technique [0002] The collection, processing and transmission of vehicle driving state signals directly affect the interactivity and real-time nature of the entire car driving simulation system. It is an important indicator to measure the practical performance of a car driving simulator. [0003] In traditional car driving simulators, for the inclination change signals of the vehicle accelerator pedal, foot brake pedal, and clutch pedal, angle or displacement sensors are mainly used to detect the changes in the attitude of the parts; for the extraction of gear and hand brake signals, there are more Use Hall switch or travel switch to ...
