Description
Technical Field
The invention relates to the technical field of vehicle control, in particular to a control method, a device and a system for an active suspension control mode.
Background
The suspension system is a general term for all force transfer devices between a frame and an axle of an automobile, and has the functions of transferring and buffering force and moment acting between wheels and the frame, buffering impact load transferred to the frame or an automobile body from an uneven road surface, attenuating vertical vibration of the automobile body and ensuring riding comfort of members and operating stability of the automobile.
At present, an automobile suspension system is divided into a passive suspension and an active suspension, wherein the Damping characteristic of a shock absorber is fixed and cannot be adjusted before a vehicle leaves a factory in the traditional passive suspension, and a Control system (namely, a Continuous Damping Control system (CDC) Control system for short) of the active suspension can adjust the Damping force of the shock absorber in real time according to comprehensive judgment of different road conditions, emergency operation (acceleration/braking/steering) of a driver, real-time motion conditions of the vehicle and the like, so as to realize riding comfort and operation stability.
In order to meet the requirements of drivers on different performances and different driving feelings of the vehicle, different driving modes are configured on the vehicle, including a sport mode, an economy mode, a comfort mode and a self-defined mode. The driving mode selection mode is diversified, and each host factory has own characteristics, including various modes such as solid keys or knobs, soft keys of instruments or central control, solid keys and soft key combinations and the like. The control of the driving mode may be performed by combining various controls such as a power output characteristic of the engine or the motor, a steering assist control characteristic, a pedal assist control characteristic, an active suspension control characteristic, and an energy recovery intensity characteristic so as to correspond to different driving modes.
In the existing active suspension control mode control schemes, the active suspension control characteristics are mostly corresponding to the driving mode, such as: the motion mode corresponds to the control characteristic of a 'hard' type active suspension, the comfort mode corresponds to the control characteristic of a 'soft' type active suspension, and the economic mode corresponds to the control characteristic of a 'normal' type active suspension. This control is similar to the all terrain mode, i.e. the driver selects the appropriate driving mode (i.e. control characteristic) depending on the road conditions. The control mode has certain hysteresis, has certain requirements on the driving experience of the driver, and still brings poor driving performance if the driver does not select or switch the mode in time.
