All new Volvo S80 safety systems
Active safety up to the... heartbeat detection

The all-new Volvo S80 executive sedan.

The all-new Volvo S80 Executive (E segment) sedan / saloon.

APN,
17th March 2006.

When it hits the showrooms this June, the all new Volvo S80 will bring with it a new generation of advanced driving and support systems such as the Personal Car Communicator – a pocket-sized security control, or the BLIS and IDIS systems which make it easier to control the driving situation, or other advanced functions to help reduce the braking distance.

Most obviously, safety starts with the clearest possible vision, and here, the swivelling headlights improve the range of vision at night (prices, standard and optional equipment are to be checked depending on markets). The owner of the 2nd generation S80 can even now, at a distance, detect possible intruders in the car.

For Silvia Güllsdorf, S80 Project Director at Volvo Cars, “The basic principle [in] preventive safety systems is that they should not take over the driving or the driver’s responsibility... the aim is to help the driver to make the correct decision in difficult situations by issuing a warning and, in different ways, indicate how to deal with the situation.”

Volvo S80 ACC, Adaptive Cruise Control.

Adaptive Cruise Control uses a radar sensor to measure continuously the distance to the vehicles in front and automatically adapts the speed of the car to help ensure the distance is not too short.

Adaptive Cruise Control - To help maintain a safe distance to the car in front, Volvo Cars has developed the Adaptive Cruise Control, ACC. Volvo presents it in the first instance as a comfort function, but at the same time it contributes to more controlled driving when the traffic flow is uneven. It uses a radar sensor to measure continuously the distance to the vehicles in front and automatically adapts the speed of the car to help ensure the distance is not too short.

The driver activates the cruise control, setting the desired maximum speed at between 30 and 200 km/h and chooses the minimum time interval to the cars in front. There are five different time intervals to choose from.

Collision Warning with Brake Support - In many rear-end collisions, the reason is that the driver was distracted and failed to react in time. Volvo Cars' Collision Warning with Brake Support system, CW, offers support functions that help to avoid rear-end collisions or minimise the effect of such a collision.

The Collision Warning with Brake Support system continuously monitors the space ahead of the car with the aid of a radar sensor. The system is activated in different ways at different phases throughout the whole course of events.

If the car approaches another moving car from behind and the driver does not react, a red warning light flashes on the windscreen. At the same time, an audible signal can be heard. In certain situations this is sufficient for the driver to react and avoid the hazard.

If the risk of a collision increases, despite the warning, the brake support is activated. To shorten the reaction time the brakes are prepared by the brake pads being placed against the discs. The brake pressure is also reinforced hydraulically, ensuring effective braking even if the driver does not press the brake pedal particularly hard.

“If the speed is not too high the brake support will help reduce the effect of a collision,” says Silvia Güllsdorf. “But it is always the driver’s reactions that are crucial to the outcome.” If a driver brakes hard the brake lights begin to flash to warn the drivers of cars following behind. When the speed is reduced to less than 30 km/h the hazard warning lights are also activated. To adapt the warning system to different conditions and individual driving styles the sensitivity can be regulated in the setting menu in the car. There are three alternative sensitivity positions.

Advanced information systems - The all new Volvo S80 is also equipped with BLIS (Blind Spot Information System) and IDIS (Intelligent Driver Information System), two systems that help the driver maintain better control over the driving situation.

BLIS detects blind spots

 BLIS detects blind spots and alerts the driver as necessary.

With the aid of cameras beside the door mirrors, BLIS registers if another vehicle is in the blind spot alongside the car. In such a situation a warning light beside the mirror is activated to alert the driver and improve the scope to make the correct decision.

IDIS is an electronic information system that contributes to the driver not being distracted by unnecessary information in stressful situations. By continuously checking certain functions in the car, such as wheel movements, movement of the accelerator pedal, indicator control and braking, IDIS can assess the complexity of the situation. The information is processed and at a certain level any information that is not crucial to safety, such as an incoming telephone call or a text message, is delayed.

The new Volvo S80 in brief

The new S80 body is 4851mm long, 1860mm wide, 1490mm high, with a 2835mm wheelbase. Luggage volume is 480 litres.

It will be launched first with engine options (all have aluminium cylinder head and block):
- 5-cylinder petrol, 2521cc, light pressure turbo, 200 hp/4800 rpm, and 300 Nm at 1500-4500 rpm, 6-speed manual or automatic transmission, front-wheel drive.
- 5-cylinder turbo diesel, 2400cc, 185 hp/400 rpm, and 400 Nm at 2000-2750 rpm, or 163hp/4000 rmp and 340 Nm at 1750-2750 rmp, with 6-speed manual or automatic transmission, front-wheel drive.
-
6-cylinder (inline) petrol, 3192cc, 238 hp/6200 rpm, and 320 Nm at 3200 rpm, 6-speed automatic transmission with front-wheel drive.
- V8 cylinder petrol, 4414cc, 315 hp/5950 rpm, and 440 Nm at 3950 rpm, 6-speed automatic transmission with all-wheel drive.

Active, swivelling Bi-Xenon Light – To produce an optimal range of vision when driving in the dark on winding roads, Volvo Cars has launched the Active Bi-Xenon Light – swivelling headlights that follow the bends in the road.

A mini-processor is used to measure and analyse a number of parameters and optimise the light to suit the situation. The headlights can be swivelled by up to 15 degrees in each direction, totalling 30 degrees, and thus have the capacity to illuminate a longer distance when the road is winding.

To save wear on the system, this function is disconnected automatically in daylight. To help reduce the risk of blinding oncoming road users the angle of the headlights is adjusted depending on how heavily the car is loaded or if it is accelerating or braking.

The headlights are cleaned by means of an electro-mechanical, high-pressure system that washes one headlight at a time, always offering the best possible light.

New brake functions - The all new Volvo S80 gets an advanced braking system too with several new functions that interact to reduce the braking distance in all situations.

First, the Hydraulic Brake Assist (HBA) is a new generation of Volvo’s panic brake assistant. As opposed to earlier systems, which are based purely on vacuum, the braking pressure is also reinforced hydraulically. In an emergency situation where the driver does not press the brake pedal sufficiently hard, HBA helps to ensure the ABS system is used optimally and the braking distance shortened.

The Optimised Hydraulic Brakes (OHB) reinforce the braking capacity in conjunction with hard braking by using hydraulics to compensate for low vacuum pressure in the brake servo.

The Ready Alert Brakes (RAB) can anticipate rapid braking and place the brake pads against the brake discs even before the driver presses the brake pedal. In doing so, the braking system’s reaction time – and braking distance – is shortened. The signal to the braking system could be that the accelerator pedal is released quickly or that the Adaptive Cruise Control registers an obstacle in front of the car.

The Fading Brake Support (FBS) uses hydraulics to gradually build up the braking pressure in conjunction with persistently hard braking to help reduce the risk of wear and retained pedal feeling.

Personal Car Communicator with a heartbeat sensor - Personal security is one of the cornerstones of the Volvo brand image. Launched also with the all new S80, the Personal Car Communicator (PCC), an advanced, pocket-sized control function is like a normal remote control but can do much more than activate locks and alarms. By simply pressing a button the car owner can within a few seconds acquire information about:
- whether the car is locked or unlocked,
- whether the alarm is activated or not,
- whether the alarm is activated and if there is someone in the car, which is registered using a highly sensitive heartbeat sensor and an advanced calculation process.

The information is accessible and relevant as long as the distance between the PCC and the car is within approximately 100 metres. However, the most recent information is stored so that at any time and in any place a check can be made to see if the car was actually locked when it was parked.
