- Company Profile:
A subsidiary of Volkswagen, the Audi Group, comprising the two brands Audi and Lamborghini, is one of the world’s leading carmakers in the premium and supercar segment. The core of the Company is the Audi brand. It offers its products under both the Audi and Lamborghini brands, as well as sells ...
The dynamic shift program (DSP) is part of automatic and Tiptronic transmissions (the multitronic has a dynamic regulating program (DRP)). It reduces the driver’s workload, particularly in stop-and-go traffic. DSP independently selects the optimum driving range. The transmission automatically recognizes the vehicle’s driving characteristics and adapts its shift strategy to the prevailing conditions. DSP-controlled transmissions are also very easy to maintain and, for example, do not need transmission oil changes.

The Audi dynamic suspension found on the new A6 unites apparent opposites: sporty driving dynamics and outstanding ride comfort. It comprises a refined version of the 4-link front suspension and the trapezoidal-link rear suspension familiar from the Audi A8 and Audi A4. The four-link front suspension guarantees maximum steering comfort and extremely precise steering sensitivity. As far as kinematics is concerned, the trapezoidal-link rear suspension has been developed with the focus on its sporting characteristics, one of the key development goals of the new Audi A6. An identical rear suspension design is used for front-wheel-drive and quattro models, which also helps to optimize chassis tuning. Thanks to the considerable increase in body rigidity of around 34 percent compared with the previous model, it has been possible to increase the spring rates at the front axle and to reduce them at the rear axle, and adjust damping forces accordingly. The results are a reduction in unwanted body vibration, greater directional stability and improved traction.

As the name implies, easy entry is designed to make access to the rear of the car easier by folding the front seat back forward as far as possible while sliding the seat cushion forward. Audi installs this convenient design in its two-door models, and for the third row of the Audi Q7. The easy entry feature not only makes rear-seat access easier, but also keeps the seat in the adjustment position previously selected. An additional lever enables the driver to activate the easy entry feature for the front passenger’s seat.

“E” stands for “electronic.” In cars equipped with e-gas, the accelerator pedal acts like a sensor. Based on the position of the pedal, it immediately recognizes the performance the driver wants. This output signal is used to adjust the engine management system, the throttle plate, turbocharger boost pressure and ignition. This electronic system takes the place of the traditional control technology via Bowden cable and offers significant advantages: e-gas simplifies electronic engine management, responds more quickly and is a technical prerequisite for the electronic stabilization program (ESP).

The electromechanical parking brake has little in common with a conventional handbrake. It is resistant to wear, its braking effect is permanently constant and it cannot lock. It is activated by pulling the small electric lever on the center console, which replaces the conventional handbrake lever. It is released automatically when the car departs, and does not have to be released manually even when performing a hill start. The integral starting assist function determines the selected gear, accelerator position, engine speed, torque, direction of travel and the vehicle's angle of inclination. This prevents the car from rolling back when the parking brake is released automatically.
The brake can only be released manually if the foot brake is depressed at the same time. In the event of an emergency braking maneuver via the parking brake, the vehicle can be braked considerably more effectively than with a conventional handbrake because braking takes place via the normal service brake with the aid of the vehicle's electronic stabilization program (ESP) functions. All the benefits of the anti-lock brake system (ABS) and electronic brake-force distribution (EBD) are exploited.
Industry:Automotive
Electronic brake-force distribution (EBD) and the anti-lock brake system (ABS) constitute one unit inasmuch as they share a number of the same parts. EBD ensures maximum braking performance at the front and rear wheels, and under normal conditions it prevents the rear-end from braking away because of over-braking. The system also counteracts “fading” as a result of overheating.

The electronic differential lock (EDL) permits smooth, comfortable starts on road surfaces that do not have a uniform coefficient of friction. If a wheel starts to spin, EDL brakes it as necessary so that power is transmitted to the wheel with the better traction. EDL reduces tire wear and works up to about 25 mph (quattro: up to about 50 mph). EDL is part of the electronic stabilization program (ESP) and the traction control (ASR).

The principal task of electronic engine management is coordination of all parameters through continuous process control in order to assure economical and ecological engine operation. The parameters controlled include ignition timing, the amount of fuel injected, injection timing and exhaust gas recirculation, as well as throttle plate position, variable intake manifold positions, turbine geometry (on engines with turbocharger) and the camshaft settings (on spark-ignition engines). In order to perform these tasks, the electronic engine management system also monitors the engine speed, engine temperature, fuel grade (via knock sensor) and accelerator pedal position. Deviations from normal operation are stored with corresponding information in the system memory.

The immobilizer is an electronic anti-theft device. It is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car’s electronics. The immobilizing is only cancelled if the key sends an authorization code. New encryption technology protects the system against electronically copied vehicle keys.
Note: No system can provide 100% protection against theft. If thieves possess the necessary skill and determination, they may even be able to overcome the electronic immobilizer.

The electronic stability control helps make the vehicle easier to control in handling situations close to the limit. It reduces the danger of swerving and thus improves directional stability. Electronic stability identifies the car's intended direction and response. It applies the brakes on individual wheels, thereby generating one-sided forces that help to keep the car moving in the desired direction. The program uses the anti-lock brake system (ABS), electronic brake-force distribution (EBD), the electronic differential lock (EDL) and the traction control (ASR) system, and is permanently active.
The latest version, ESP 8.0 also offers a dry brake function. In adverse weather conditions, the system wipes water off the brake discs at regular intervals by applying the brake pads. This process goes unnoticed by the driver and reduces the stopping distance in wet weather compared with conventional brake systems.
Note: ESP cannot override a car's physical limits. If a driver pushes the possibilities of the car's chassis and ESP too far, ESP cannot prevent an accident.
