Active Stabilizer Suspension System
Active Power Stabilizer Suspension System (APSSS), is an electric active suspension system with active anti-roll bars developed by Toyota Motor Corporation for its high-end vehicles including Lexus models. By altering stabilizer bar stiffness, this system acts to reduce body tilt during cornering, keeping the vehicle more level during turns and improving handling, as opposed to the natural tendency of a vehicle to roll due to the lateral forces experienced during high-speed maneuvering. The active stabilizer system relies on vehicle body sensors and electric motors. The first production usage of this system was introduced in August 2005 with the Lexus GS430 sport sedan, followed by the 2008 Lexus LS 600h luxury sedan. The development of APSSS is claimed to be the world's first electric active stabilizer system. It is a system improvement of an earlier Toyota technology called Toyota TEMS (Toyota Electronic Modulated Suspension). How it works The APSSS utilizes sensors for ste ...

Lexus GS 450h Obsidian
is the luxury vehicle division of the Japanese automaker Toyota. The Lexus brand is marketed in more than 90 countries and territories worldwide and is Japan's largest-selling make of premium cars. It has ranked among the 10 largest Japanese global brands in market value. Lexus is headquartered in Nagoya, Japan. Operational centers are located in Brussels, Belgium, and Plano, Texas, United States. Created at around the same time as Japanese rivals Honda and Nissan created their Acura and Infiniti luxury divisions respectively, Lexus originated from a corporate project to develop a new premium sedan, code-named F1, which began in 1983 and culminated in the launch of the Lexus LS in 1989. Subsequently, the division added sedan, coupé, convertible and SUV models. Lexus did not exist as a brand in its home market until 2005, and all vehicles marketed internationally as Lexus from 1989 to 2005 were released in Japan under the Toyota marque and an equivalent model name.

Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Dynamic Suspension System
The Kinetic Dynamic Suspension System (KDSS) technology was employed initially in the Lexus GX 470, and subsequently the 200 Series Toyota Land Cruiser. The system was invented and developed by Kinetic Pty Ltd, a small R&D company based in Dunsborough, Western Australia. It optimally adjusts front and rear stabilizers based on a set of interconnected hydraulic cylinders. The interconnection is made up of hydraulic piping and a control cylinder which is located at the frame rail. KDSS, which is fully mechanical, can disengage the stabilizer bars (the bars are jointed, allowing movement independent of one another). This system will not engage during normal driving conditions, when hydraulic pressure is equal. In off-road conditions, KDSS activates when it senses that a wheel has dropped. The Kinetic Dynamic Suspension System was first available as an option on the model year 2004 Lexus GX 470, a sport utility vehicle that was only sold in North America, and based roughly on the ...

Height Adjustable Suspension
Height adjustable suspension is a feature of certain automobile suspension systems that allow the motorist to vary the ride height or ground clearance. This can be done for various reasons including giving better ground clearance over rough terrain, a lower ground clearance to improve performance and fuel economy at high speed, or for stylistic reasons. Such a feature requires fairly sophisticated engineering. Height adjustment is most often achieved by air or oil compression used for the "springs" of the vehicle when the pressure is varied the vehicle body rises or lowers. Factory systems for cars The first instance of a production vehicle with adjustable suspension was on the 1954 Citroën 15CVH. This vehicle featured a self-leveling, height adjustable hydropneumatic suspension. Since this time, these systems have appeared continuously on Citroën models, including the DS and CX. Height adjustable suspension was banned in the United States from 1974 to 1981, due to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Suspension
An active suspension is a type of automotive suspension on a vehicle. It uses an onboard system to control the vertical movement of the vehicle's wheels relative to the chassis or vehicle body rather than the passive suspension provided by large springs where the movement is determined entirely by the road surface. Active suspensions are divided into two classes: real active suspensions, and adaptive or semi-active suspensions. While semi-adaptive suspensions only vary shock absorber firmness to match changing road or dynamic conditions, active suspensions use some type of actuator to raise and lower the chassis independently at each wheel. These technologies allow car manufacturers to achieve a greater degree of ride quality and car handling by keeping the tires perpendicular to the road in corners, allowing better traction and control. An onboard computer detects body movement from sensors throughout the vehicle and, using that data, controls the action of the active and semi-act ...

Lexus RX 450h
The is a luxury crossover SUV sold since 1998 by Lexus, a luxury division of Toyota. Originally released in its home market of Japan in late 1997 as the Toyota Harrier, export sales began in March 1998 as the Lexus RX. Considered as the first luxury crossover SUV, four generations of the RX have been produced to date, the first being compact in size, and the latter three classified as mid-size. Both front- and four-wheel drive configurations have been used on the RX series, and several gasoline powertrain options, including V6 engines and hybrid systems, have been offered. In the Lexus model lineup, the RX sits below the larger GX and LX (marketed as the Toyota Land Cruiser Prado and the Toyota Land Cruiser body-on-frame SUVs outside North America), and above the smaller NX crossover with a lesser displacement inline-four engine. The name "RX" stands for "Radiant Crossover". It has also been labelled as "Recreational Cross Country" in some markets. The RX's current Toyota c ...

Model Year
The model year (sometimes abbreviated "MY") is a method of describing the version of a product which has been produced over multiple years. The model year may or may not be the same as the calendar year in which the product was manufactured. Automobiles United States and Canada Automobiles in the United States and Canada are identified and regulated by model year, whereas other markets use production date (month/year) to identify specific vehicles, and model codes in place of the "year" (model year) in the North American make-model-year identifier. In technical documents generated within the auto industry and its regulating agencies such as the U.S. National Highway Traffic Safety Administration and United States Environmental Protection Agency and Transport Canada and Environment Canada, the letters "MY" often precede the year (as in "MY2019" or "MY93"). Even without this prefix, however, in the North American context it is usually the model year rather than the vehicle' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomechanism
In control engineering a servomechanism, usually shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the action of a mechanism. On displacement-controlled applications, it usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast a car's cruise control uses closed-loop feedback, which classifies it as a servomechanism. Applications Position control A common type of servo provides ''position control''. Commonly, servos are electric, hydraulic, or pneumatic. They operate on the principle of negative feedback, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...
