F-PACE | ADVANCED DRIVER ASSISTANCE SYSTEMS

The all-new F-PACE offers all of technologies needed to make journeys easier and safer, from traction systems to get you moving on low friction surfaces to an emergency braking system that can recognise pedestrians

All Surface Progress Control: Forward motion in difficult conditions

Snow, ice, wet grass: pulling away smoothly on surfaces such as these can be challenging, especially if you're starting on a slope – apply even slightly too much throttle and the wheels can spin. Even if you do get moving, it's another challenge still to maintain your momentum. Conventional traction control systems can help, but they only step in after the wheels begin to slip, which is usually too late.

Jaguar's revolutionary All Surface Progress Control (ASPC) system is completely different. Leveraging the knowledge built up over decades of Jaguar Land Rover experience in off-road technologies, ASPC delivers a step-change in capability because drivers don't use the pedals: they just have to steer.

As well as fine control of the throttle, ASPC also uses the brakes in opposition to the throttle so that from standstill, only very low engine torque is applied to the driven wheels. The result is smooth, controlled progress with little or no wheel spin.

ASPC functions like a low-speed cruise control and can operate between 3.6km/h and 30km/h. After activating the system by pressing a button on the centre console, the driver uses the cruise control switches on the steering wheel to set the maximum speed. After that, the system does all the hard work. The system is available on all engines paired with automatic transmissions and is compatible with rear- and all-wheel drive. ASPC is made even more effective by the fitment of winter tyres.

Low Friction Launch: Maximum traction, manual control

While ASPC makes the most of the vehicle's traction capability by taking control of the throttle, some drivers want to achieve similar results while operating the throttle for themselves. The Low Friction Launch (LFL) function has been designed to do this and the all-new F-PACE is the first vehicle to offer it.

The driver selects LFL using the touchscreen. Once activated, it changes the throttle map to one which results in a very progressive torque response from the engine, enabling the driver to pull away smoothly. Like ASPC, LFL is available on all engines mated to automatic transmissions.

Vision of the future: Stereo camera boosts active safety

State-of-the-art vision sensors will enable highly automated and autonomous driving functions in the near future. Such a sensor is fitted to the all-new F-PACE already, and this forward-facing stereo camera is at the heart of many of its advanced driver assistance systems.

Providing a highly accurate 3D view of the road ahead, the stereo camera is ideal for Autonomous Emergency Braking (AEB) systems. The all-new F-PACE is the first Jaguar to offer an AEB system with a pedestrian detection function. If the system's controller determines that a collision with a vehicle or a pedestrian is imminent, full braking is initiated automatically. The driver also receives visual and audible warnings for speeds above 40km/h immediately before the AEB activates.

The stereo camera also provides the intelligence for the Lane Departure Warning (LDW) and Lane Keep Assist (LKA) systems. By monitoring the vehicle's position relative to lane markings either side, LDW can help to prevent drivers from drifting out of lane by triggering a visual warning in the instrument panel and a haptic warning through the steering wheel rim. LKA can guide the driver back towards the centre by applying a small amount of counter-steering through the electric power-assisted steering system. The torque applied to the steering wheel can be easily over-ridden by the driver.

Failure to stay in lane is often due to a lack of concentration but driver fatigue can also be a factor. Such tiredness may be characterised by periods of little or no steering activity followed by sudden or excessive inputs. The Driver Condition Monitor system recognises these patterns, and, by also checking the useage of the brake and accelerator pedals, the direction indicators and various buttons on the instrument panel, will show a multi-stage warning in the instrument cluster and give audible warnings to prompt the driver to take a break.

The all-new F-PACE's Traffic Sign Recognition (TSR) system uses the stereo camera to keep the driver informed of the speed limit – including temporary limits which apply in road works, for example, variable limits on motorways, or reduced limits when towing. The limit is displayed in the instrument cluster and the head-up display, and camera data is always cross-referenced against GPS data for maximum robustness. If the driver selects the over-speed warning function, the ring around the sign graphic flashes whenever the limit is exceeded, giving an unobtrusive prompt to slow down.

Further support for the driver comes from the Intelligent Speed Limiter (ISL). This can use TSR system data to adjust the set point and can automatically increase or decrease the vehicle's maximum speed while the accelerator pedal is pressed. If the TSR system recognises a higher speed limit ahead, the ISL system notifies the driver and the vehicle can accelerate smoothly up to the new limit. If the speed limit is lower, the vehicle can be slowed down accordingly.

A clear advantage: Laser head-up display

Projecting the most important information onto the windscreen enables the driver to focus on the road ahead. The all-new F-PACE's laser head-up display (HUD) can put information such vehicle speed, turn-by-turn navigation instructions and speed limits right in the driver's eye line, minimising the amount of time spent glancing down at the instrument cluster. The colour images are exceptionally sharp and are adjustable both in height and in brightness; the HUD can also be switched off if desired.

Laser technology is unique in this segment and offers several advantages over conventional TFT systems: smaller and almost a third lighter, the images it generates offer superior colour saturation and higher contrast, so they remain clear even in bright sunlight.

Keeping your distance: Adaptive Cruise Control with Queue Assist

As well as reducing driver workload when cruising on the motorway, the all-new F-PACE's Adaptive Cruise Control system (ACC) can also help to relieve the monotony of driving in heavy traffic, thanks to the queue-assist function. The long-range radar will maintain a safe distance to the vehicle in front, all the way down to a standstill. Press the accelerator again, and the all-new F-PACE will pull away again and track the vehicle in front, at a safe distance, all the way up to the chosen speed setting.

Looking out for you: Blind Spot Monitor and Reverse Traffic Detection

By monitoring the area behind the vehicle, radar can assist the driver in other scenarios too. Medium-range sensors can make overtaking safer by warning the driver of other vehicles approaching fast from behind. As they approach the blind spot, a flashing icon appears in the door mirror to alert the driver of the potential danger. As the vehicle enters the blind spot, the icon becomes solid.

The same medium-radar sensors can help to improve safety at slower speeds too. When reversing out of parking spaces, other vehicles approaching from either side – which may not be visible to the driver – are detected by the radar. If they present a potential hazard, the driver is given audible and visual warnings.

Room to manoeuvre: Park Assist

To help the driver to park in even the tightest spaces, the all-new F-PACE offers semi-automated park assist functions for parallel and bay parking manoeuvres. The vehicle's ultrasonic sensors first measure the space, and, if the system decides that it's suitable, will enable the vehicle to steer itself in – the driver just has to control the accelerator and the brakes. The system can also steer the vehicle out of parallel spaces.
