DESC:SYSTEM FOR AUTO ADJUSTMENT OF VEHICLE SUSPENSION
Field of the invention:
The present invention relates to the vehicle suspension systems, and more particularly, to a system for auto adjustment of suspension using the road conditions from GPS.
Background of the invention:
The main factor which affects ride quality is the stiffness of suspension components. Several technologies have evolved to have an auto adjustment feature in the suspensions, seating arrangements, and many other elements in the passenger or SUV vehicles which are done manually or semi-automatically based on a choice of a rider. Baring a few expert rider’s actual suspension condition which is suitable for better comfort is an unknown area. Also, the undesired adjustment would affect the rider health condition adversely.
The science of acceptable ride comfort in terms of vehicle frequency and damping force reaction on the human body for comfortable or advisable frequency is a special parameter to be worked out and incorporated. It is difficult to have the skills of acceptable or ideal ride comfort for a healthy and recommended ride, which a non-expert rider cannot estimate and tune the system.
Hence, there is a need to develop an integrated system for suspensions complimenting driverless vehicles for automatic capturing of road conditions and the external environment.
Accordingly, there exists a need to provide a system for auto adjustment of suspension based on GPS inputs that overcomes the above-mentioned drawbacks in the prior art.

Objects of the invention:
An object of the present invention is to provide a system for auto adjustment of vehicle suspension using GPS inputs.
Another object of the present invention is to provide a system for auto adjustment of vehicle suspension based on road conditions.
Summary of the invention:
Accordingly, the present invention provides a system for auto adjustment of the vehicle suspension. The system comprises a front console (10), a central control unit (20). The central control unit comprises a GPS receiver, a memory unit, a processing unit, a first communication module, and a second communication module. The central control unit (20) receives information regarding the actual road conditions on potholes, road humps, cornering, speed of the vehicle, reaction while acceleration, vehicle vibration frequency, number of passengers riding, and the like from the GPS. The central control unit (20) processes this information and accordingly varies the suspension functioning automatically without any intervention of the rider.
Brief description of the drawings:
The objects and advantages of the present invention will become apparent when the disclosure is read in conjunction with the following figures, wherein
Figure 1 shows a schematic of a system for auto adjustment of suspension based on radar, in accordance with the present invention.
Detailed description of the embodiments:
The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
The present invention provides a system for auto adjustment of the vehicle suspension. The present system adjusts the suspension of the vehicle based on GPS inputs.
The present invention is illustrated with reference to the accompanying drawings, throughout which reference numbers indicate corresponding parts in the various figures. These reference numbers are shown in bracket in the following description.
Figure 1 shows, the system for auto adjustment of vehicle suspension (hereinafter, “the system (100)). The vehicle comprises a suspension unit (110) with a pair of front shock absorbers (A, B) and a pair of rear shock absorbers (C, D). The system (100) comprises a front console (10), and a central control unit (20).
Usually, the suspension unit (110) of a vehicle is set to a fixed ride comfort based on the type of vehicle and original vehicle tune as per an expert rider for a general road condition and an average acceptable comfort depending on the road conditions and a normal rider.
The front console (10) is mounted in the vehicle. The front console (10) comprises any one from a display unit, an audio device, or a combination thereof.
The central control unit (20) is connected with the front console (10) using a hardwired CAN network. In an embodiment, the central control unit (20) is located near the front console (10). Further, the central control unit (20) comprises a GPS receiver, a memory unit, a processing unit, a first communication module, and a second communication module.
The central control unit (20) is operably connected with the suspension unit (110) using a first communication module. In an embodiment, the first communication module is a Bluetooth connection.
The GPS receiver is designed to capture all the conditions which affect ride comfort, including actual road conditions and vehicle driving conditions. The data from the GPS receiver is stored in the memory unit. The memory unit includes a computer program and a plurality of processing instructions stored therein. The computer program checks the traffic condition of the road using GPS inputs. Further, the memory unit provides the digital inputs from the GPS receiver to the processing unit for data processing.
The captured information includes, but not limited to, the actual road conditions on potholes, road humps, cornering, speed of the vehicle, reaction while acceleration, vehicle vibration frequency, number of passengers riding, and the like. The processing unit processes the receiver data to collaborate with the functioning of the suspension unit (110) for different driving modes related to any one of the soft ride, hard ride, and flushing ride.
The processing unit integrates the GPS data and accordingly provides inputs to the suspension unit (110) for its adjustment suitable for a benchmarked for intelligent ride comfort with any abnormalities or riding conditions exists. The functioning of the suspension unit (110) is automatically controlled without any intervention of the rider. Further, the automatic functioning control of the suspension unit (110) provides a better ride comfort which gets adjusted/tuned to a recommended level for any change in the external environment.
The system (100) taps the authentic data of the real conditions of the road, vehicle riding conditions, the external environment for speeding, braking, accelerating, and several other parameters which can affect the ride comfort and safety of the auto driving experience.
The driving modes are selected from any one of a comfort mode and a sports mode. The system (100) operates the suspension unit (110) in comfort mode on a rough road and in sports mode on smooth roads such as highways. The system (100) notifies the rider about the suspension mode by means of the front console (10).

Advantages of the invention:
1. The system (100) provides automatic tuning of the suspension to a recommended level of ride comfort.
2. The system (100) utilizes the latest technology of GPS and adjustable suspension system for better performance and rider health.
3. Eliminates the mistake of a rider’s skill/experience for any abnormal or unacceptable adjustment of suspension.
