Description

Technical Field

[0001] This invention relates to the field of automotive functional testing, and more particularly to a static driving simulation device for automotive intelligent driving systems. Background Technology

[0002] Hardware-in-the-loop (HIL) testing is one of the three pillars of testing for intelligent driving systems. With the automotive industry's shift towards intelligent connectivity, especially the development of Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD) systems, unprecedented demands are being placed on the breadth, depth, and efficiency of testing and verification. Real-vehicle road testing suffers from inherent bottlenecks such as high cost, long development cycles, high safety risks, and difficulty in reproducing extreme and dangerous scenarios. Therefore, hardware-in-the-loop (HIL) testing based on driving simulators can serve as a key technological path to address this challenge.

[0003] A driving simulator is a driver-in-the-loop simulation system used to reproduce the vehicle driving experience and traffic environment. Its core value lies in enabling driving behavior research, vehicle performance evaluation, and testing and verification of intelligent driving systems in a safe, controllable, and repeatable laboratory environment.

[0004] Current driving simulators mainly consist of a man-made cockpit, including a seat, steering system, brakes, accelerator pedal, and other mechanisms. A monitor is installed in front for scene projection. The simulator's steering, braking, and accelerator signals are transmitted to a dynamic model to realize the driver's input. However, the drawback of the existing solution is that the driving simulator only serves as the input for steering, braking, and accelerator signals, mainly verifying the driver's driving operation and experience. It cannot achieve the testing of advanced intelligent driving functions, nor can it meet the needs of different vehicle models. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:

[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] This invention proposes an embodiment of a static driving simulation device for an intelligent driving system for automobiles, specifically, as follows: Figure 1 As shown, it includes: a seat mounting panel for mounting the driver's seat, a control mounting panel for mounting the steering mechanism, pedal mechanism, and gear shift mechanism, and an instrument panel mounted above and behind the steering wheel, with the instrument panel connected to the first guide rail. The MP5 is slidably mounted on the first guide rail, so that the MP5 can be adjusted to the left and right sides along the guide rail according to the left and right drive vehicle models.

[0028] The display screen (such as a 43-inch triple display screen) is slidably connected to the screen rail via a fixed bracket. Similarly, the display screen can be moved left and right as a whole depending on whether the vehicle is left- or right-hand drive; and,

[0029] An adjustable DMS camera clamping device is used to fix a DMS camera that monitors the driver's status. Specifically, the clamping device may include: a base connected to both ends of a main rod and an adjustable hose. The base is non-fixed to allow for movement as needed, and the adjustable hose can be bent at multiple angles to facilitate placing the DMS camera in the actual vehicle position.

[0030] Furthermore, the structure of the static driving simulation device can be supplemented by the fact that the seat mounting panel is connected to a second guide rail for adjusting the fore-aft position and an adjustment bracket (including an adjustment knob) for adjusting the seat height.

[0031] Regarding the electrical signal connection method of the static driving simulation device, please refer to... Figure 2 The diagram illustrates that the front seat controller adjusts the seat via the seat motor; the cockpit domain controller is mainly used to control the tested MP5 player and instruments; more preferably, it also includes a power amplifier, which is connected to audio equipment, specifically including three types: tweeter, woofer, and midrange; a switching power supply provides power to the aforementioned front seat controller, cockpit domain controller, MP5 player, instruments, and power amplifier.

[0032] The signal acquisition board acquires signals from the pedal mechanism, steering mechanism, and gear shift mechanism, and transmits them via a CAN network to a pre-installed simulation test system (simulation software) on the server. Additionally, in actual operation, the signal acquisition board can output several signals via a COM interface (detailed below), such as a USB connector, for easy software rewriting. The simulation test system is connected to the display screen via the server's HDMI interface. It should be noted that the aforementioned cockpit domain controller and front seat controller are directly connected to the simulation test system via the server's CAN interface, without being associated with the signal acquisition board; this is for ease of vehicle model switching. The server and display screen are powered by 220V AC mains power.

[0033] More preferably, in some other embodiments, the CAN signals of the cockpit domain controller, power amplifier, and signal control board (including signal acquisition card) are combined into one channel to facilitate signal acquisition for debugging and simulation testing of the system.

[0034] Specifically, the signals output by the aforementioned signal acquisition board can include: turn signals, light signals, wiper signals, gear position signals, steering angle signals, accelerator signals, and brake signals. The specific signal value correspondences are as follows:

[0035] Turn signals: 0 for no action, 1 for left turn, 2 for right turn;

[0036] Light signal: 0 for off, 1 for on;

[0037] Wiper signal: 0 for off, 1 for on;

[0038] Gear position signals: 1 for P, 2 for R, 3 for N, 4 for D;

[0039] Corner signal: -560~560 degrees;

[0040] Throttle signal: 0-255 value, corresponding to brake position 0-1;

[0041] Brake signal: 0-255 value, corresponding to 0-1 throttle position;

[0042] All of the above signals can be transmitted to the simulation test system via the CAN line.

[0043] Finally, based on the foregoing, a signal function in another preferred embodiment of the present invention is described in detail. The signal acquisition board is connected to the steering wheel wash knob via a CAN cable to control the one-button steering wheel return function: when the steering wheel direction cannot be determined, the steering wheel can be returned to center by rotating the wash knob out / back; the return angle can be calibrated by writing the preset 0-position signal through the USB interface and CAN tool to achieve zero angle.

[0044] In summary, the main design concept of this invention includes: a seat mounting panel for mounting the driver's seat; a control mounting panel for mounting the steering mechanism, pedal mechanism, and gear shift mechanism; an instrument panel mounted above and behind the steering wheel, connected to a first guide rail; an MP5 slidably mounted on the first guide rail; a display screen slidably connected to a screen rail via a fixed bracket; and a clamping device for fixing a DMS camera monitoring the driver's state. The electronic control components and electrical signal connection methods of the static driving simulation device include: a front seat controller adjusting the seat via a seat motor; a cockpit domain controller for controlling at least the MP5 under test and the instrument panel; signals from the pedal mechanism, steering mechanism, and gear shift mechanism acquired by a signal acquisition board and transmitted via a CAN network to a pre-installed simulation test system on a server, the simulation test system being connected to the display screen via the server's HDMI interface. This invention can meet the needs of high-level intelligent driving testing, realize various intelligent driving function tests such as dynamic adjustment of components and driver state monitoring, and is compatible with both left- and right-hand drive vehicles at a low cost.
