Watch BMW iNsights Dynamic Performance Control Technology





Dynamic Performance Control switches power between the left and right rear wheels to stabilise the vehicle within milliseconds and help increase traction and lateral acceleration. Handling is lighter and more precise during normal as well as difficult driving conditions.



How Dynamic Performance Control works can best be described in canoeing terms: if you want to turn right when canoeing in the main current, you can brake using the paddle on the right side of the canoe. This is how most common electronic stability programs work. Alternatively, you could use the paddle powerfully on the left side of the canoe in order to have more control in progressing forwards and turning right. This is the principle behind Dynamic Performance Control.



It links the standard rear differential with a mechanical planetary gear set and an electronically controlled multi-plate clutch for each rear wheel. Its mechatronical system combines informatics, electronics and mechanics to process complex data such as the yaw rate, wheel speeds, steering angle and engine torque so that it can react immediately: when required, the system ensures that drive power distribution to the rear wheels can be freely varied and increased on either side as needed. The power distribution can also be displayed on the onboard computer.



Dynamic Performance Control increases directional stability when accelerating out of bends and provides the driver with extra support when dealing with difficult driving conditions. Before under- or oversteer can take place, lateral guided force is used to keep the vehicle on track. Precise steering significantly increases driving comfort and safety.



Dynamic Performance Control is also effective when the vehicle is coasting - when the driver removes their foot from the accelerator - or when they have pressed the clutch pedal. If the rear wheels are on different types of surfaces, Dynamic Performance Control improves traction by supplying more drive power to the wheel with more grip. A wheel torque difference of up to 1,800 Nm can be actively created between the left and right rear wheels.



This increases driving stability and allows for much faster acceleration. As a logical progression to the xDrive all-wheel drive system, Dynamic Performance Control can be matched to all drive concepts and engines. Whereas xDrive variably controls the power distribution between the front and rear axles, Dynamic Performance Control intelligently distributes power between the two rear wheels. This results in precise handling whatever the driving conditions.

Audi Q7 Audi Car Driver Assistance Pre Sense System Animation



The Audi pre sense city safety system is a hi-tech super artificial intelligent technology used in Audi cars. It is also called collision avoidance system. Audi pre sense city warns the driver at city speeds it warns of impending collisions with other vehicles or pedestrians and will initiate heavy advanced braking system in an emergency. Thanks to Audi anti-crash, auto braking and crash avoidance cars technology. In the near future crash prevention cars will be more available by the year 2020.  The continuous improvement of vehicle safety is one of the foremost objectives in the development of new vehicles. New driver assistance systems that have been introduced into series production for the first time on board the Audi Q7 make a considerable contribution in this regard. On request, a number of innovative driver assistance systems are also available in the Q7, for example the radar-based Audi side assist, the optical parking system with audible and visual information and the reversing camera.

A frequent cause of accidents when changing lanes is that other vehicles are overlooked.
By continuously monitoring the adjacent lanes, in particular the area to the rear of the vehicle, the Audi side assist supports the driver during overtaking and lane-change manoeuvres and thus makes a contribution to active safety. The driver is alerted if one of the adjacent lanes is occupied by one or more road users. Despite the system’s capability, the driver must always be aware that the system serves as an aid, but cannot take the
responsibility away from the driver for his/her own decisions.

Despite the Audi side assist, it is still necessary for the driver to turn his/her head, look in the side mirror and observe the traffic. The electronic parking aid system has been further improved. Two new functions are now available to the customer. The familiar acoustic parking aid system has been expanded by a graphic screen display in the MMI. Using bar diagrams this provides the customer with a detailed depiction of the point at which a collision may occur. The bar diagrams permit the distance from the obstacle to be estimated with precision. The familiar acoustic feedback is retained.

Drivers who would prefer to get a picture of the situation behind the rear of the vehicle for themselves, can have the image from a reversing camera displayed on the MMI screen. The camera which has been integrated into the tailgate handle provides an ideal overview of the situation behind the vehicle. The camera image appears automatically when reverse gear is engaged.
