Problems solved by technology

[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] like 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 relevant data, wherein the road environment information includes visual information, such as road adhesion coefficient, road curvature, road width, road gradient and traffic flow. Therefore, the road environment detection module 1 can output the road adhesion coefficient parameter for the road surface adhesion coefficient, the road curvature parameter for the road curvature, the road width parameter for the road width, the road gradient parameter for the road gradient, The density parameter of the vehicle is output for the traffic on the road.

Embodiment 2

[0043] like image 3 As shown, according to another aspect of the present invention, a vehicle driving method is provided, comprising the following steps:

[0044] 1) First, before the vehicle starts, the current state of the vehicle, the current state of the driver and the state of the road ahead are automatically detected, and the data is transmitted and calculated by the ECU.

[0045] 2) Detect the road curvature radius ρ(t) at the current time t, and judge whether the vehicle will enter the curve, that is, judge whether ρ(t)=∞ is established; if so, it means that the vehicle is driving in a straight lane, and calculate t The road curvature radius ρ(t+Δt) at the time +Δt; if ρ(t)<∞, it means that the vehicle is about to or has entered the curve, and the road curvature radius ρ(t+Δt) at the time t+Δt is calculated.

[0046] 3) Detect the steering wheel angle imposed by the driver on the steering wheel, that is, the actual steering wheel angle δ s .

[0047] 4) Detect the ...

Abstract

The invention discloses an intelligent driving system with a driver model. The intelligent driving system comprises a driver model module, wherein the driver model module adjusts the performance of a vehicle according to driving characteristics of a driver and road environment information. By means of the intelligent driving system, the visual and touch information of the driver can be considered in the vehicle driving process, accordingly the performance of the vehicle is adjusted, and the purpose of controlling the vehicle to adapt to the people is achieved.

Description

technical field [0001] The present invention relates to the field of automobiles, in particular to an intelligent driving system including a driver model, a vehicle and a vehicle driving method. Background technique [0002] With the rapid development of automotive electronic technology, various assisted driving systems are widely used in the control field of automobiles, 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, ignoring the role of the driver when driving the vehicle, it cannot be detected. The driver's operating intention and driving needs cannot satisfy each driver's driving preferences (such as power, comfort and safety)....
