[0004] Although the current suspension system (including active suspension and semi-active suspension) can cope with complex road surfaces and provide vehicle comfort and passability, it cannot increase or decrease the suspension system of the vehicle according to the driver's driving personality. stiffness, and ignores the different requirements of different drivers on the suspension system (for example, under the same road conditions, young drivers prefer to passability, that is, the suspension damping needs to be improved; while older drivers prefer comfort, i.e. need to reduce suspension damping)

Embodiment 1
[0021] Such as figure 1 As shown, an intelligent driving system including a driver model according to an embodiment of the present invention includes: a road environment detection module 1 , a driver operation detection module 2 , a vehicle system module 3 , a driver module 4 and a driver model module 5 .
[0022] Specifically, the road environment detection module 1 is used to collect road environment information in real time and output related data, wherein the road environment information includes visual information, such as road surfaceadhesion coefficient, road curvature, road width, road slope, and traffic flow. Thus, the road environment detection module 1 can output the road surfaceadhesion coefficient parameter for the road surfaceadhesion coefficient of the road, output the curvature parameter of the road for the curvature of the road, output the width parameter of the road for the width of the road, output the slope parameter of the road for the slope of the road,...
Embodiment 2
[0043] Such as image 3 As shown, according to another aspect of the present invention, a vehicle driving method is provided, comprising the steps of:
[0044] 1) First, before the vehicle starts, it automatically detects the current state of the vehicle, the current state of the driver, and the state of the road ahead, and starts to transmit data and perform calculations through the ECU.
[0045] 2) Detect the road curvature radius ρ(t) at the current time t, and judge whether the vehicle will enter a curve, that is, judge whether ρ(t)=∞ is true; if it is true, it means that the vehicle is driving in a straight lane, and calculate t The road curvature radius ρ(t+Δt) at time +Δt; if ρ(t)<∞, it means that the vehicle is about to or has entered a curve, and the road curvature radius ρ(t+Δt) at time t+Δt is calculated.

Abstract
The invention discloses an intelligent driving system containing a driver model. The system includes a driver model module, and the driver model module adjusts the performance of the vehicle according to the driver's driving characteristics and road environment information. By applying the system of the present invention, the visual and tactile information of the driver can be taken into consideration during the process of driving the vehicle, so as to adjust the performance of the vehicle and achieve the purpose of controlling the vehicle to adapt to people.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to an intelligent driving system containing a driver model, a vehicle and a vehicle driving method. Background technique [0002] With the rapid development of automotive electronic technology, various auxiliary driving systems are widely used in the field of automotive control, such as anti-lock braking system (ABS, Anti-lock Braking System), electronic power steering system (EPS, Electric Power Steering), Traction Control System (TCS, Traction Control System), etc. However, since the setting parameters of most automotive electronic control systems are fixed, and the design of automotive electronic control systems is usually from the perspective of vehicle dynamics, while ignoring the role of the driver when driving the vehicle, it is impossible to detect The driver's operating intentions and driving needs cannot satisfy each driver's driving preferences (such as power, comfort and safe...
