Driver assistance systems

The updated Audi Q5 also drives with assistance systems that are at the top of its class. The first system is the standard driver information system with driving break recommendation, which is activated from a speed of 65 km/h (40.39 mph). It monitors steering movements and other parameters; if it recognizes waning concentration of the driver, it recommends a stop to take a break from driving.

The most complex of the optional systems is adaptive cruise control. Over a speed range from 30 to 200 km/h (18.64 to 124.278 mph), ACC maintains a desired distance to the vehicle in front of the Audi Q5 by monitoring the gap with radar and autonomously accelerating and braking within certain limits. The driver can set the distance and the control dynamics over multiple stages.

If ACC detects an impending front-end collision with a moving vehicle, the pre sense front system supports the driver and warns him or her over several stages. The first stage utilizes a gong and a red signal light; the braking system hydraulics are prepared, and the brake pads contact the discs. When the driver presses the brake pedal now, braking occurs practically instantaneously. If the driver does nothing, the second stage is initiated with a warning jolt and a brief braking action. If the driver now brakes but presses the pedal with insufficient force, brake assist increases the braking force to a level appropriate to the situation.

If the driver still does not react, the system autonomously initiates a partial braking action – it brakes the Q5 at a deceleration rate of about 3 m/s2, which is approximately one-third of the possible rate. At speeds below 30 km/h (18.64 mph), the performance SUV can autonomously brake with full braking force in an emergency – regardless of whether the vehicle ahead is moving or stationary. At speeds below 20 km/h (12.43 mph), this hard braking can often prevent an accident altogether, and in other cases it significantly reduces the speed at impact and therefore the accident severity.

Looking back with radar: Audi side assist
Audi side assist makes lane changes more relaxed. From a speed of 30 km/h (18.64 mph), radar sensors at the rear monitor traffic behind the Q5. If another vehicle is driving in the blind spot or quickly approaching from the rear, a yellow LED illuminates in the door mirror housing. If the driver still sets the turn signal to change lanes, the indicator LED becomes bright and flashes at a high frequency – a highly distinctive warning signal.

Audi active lane assist, which is activated from 65 km/h (40.39 mph), detects lane lines on the road via a small camera mounted to the interior mirror. If the Q5 approaches a line without the turn signal activated, the system helps the driver to steer back into the lane by a slight intervention in the electromechanical steering system. The driver can decide independently when the intervention should occur and whether it should be combined with a vibration in the steering wheel. If the driver chooses early correction, the system helps to keep the Q5 in the center of the given lane.

Three solutions are offered for making parking easier. The top system is park assist plus with a reversing camera. It monitors the area behind the vehicle with a fish-eye lens that is integrated in the tailgate. The images are enhanced and displayed on the MMI monitor; auxiliary lines and surfaces are shown which help the driver to steer.
