#aftermarket – Jaguar Land Rover has revealed some of the prototype technologies that its U.K.-based research team are developing to deliver autonomous driving in the future.
A Remote Control Range Rover Sport research vehicle demonstrated how a driver could drive the vehicle from outside the car via their smartphone. The smartphone app includes control of steering, accelerator and brakes as well as changing from high to low range. This would allow the driver to walk alongside the car, at a maximum speed of 4 mph, to manoeuvre their car out of challenging situations safely, or even to negotiate difficult off-road terrain.
The driver could use the smartphone to reverse the car out of a parking space if someone has parked too close for them to open the door, or allow the driver to become their own off-road spotter, to guide the car over off-road obstacles from outside the vehicle.
By walking alongside the car, the driver could continually check ramp, approach and departure angles and allow precise positioning of the vehicle when rock crawling. It could also be an invaluable aid when the vehicle is fording a stream or traversing sections made slippery by mud or snow. The remote control function will only operate if the user is within 10 metres of the car and if the smart key can be detected. The system will stop the vehicle if the driver moves out of range or gets too close.
Future possibilities for this technology could include more autonomous functionality where the driver gives a simple command from the handset to traverse an obstacle or exit a parking space, and the car does the rest.
MULTI-POINT TURN CAR
Jaguar Land Rover’s ‘Multi-Point Turn’ Range Rover is capable of autonomously manoeuvring through 180 degrees to turn the car in the road and point the car in the opposite direction. This autonomous vehicle could extricate itself from the most difficult situations, such as a dead-end roads or congested car parks, as well as performing many drivers’ least favourite manoeuvre – the three-point turn in a busy street or car park.
The system uses sensors to assess available space and to avoid pedestrians, vehicles, and other objects. The system takes over gear selection, steering, braking, and acceleration to make as many forward and backwards movements as necessary to achieve the manoeuvre.
The research team is working on a system to scan the environment around the car and inform the driver whether it is safe to perform the turning manoeuvre. The driver then confirms the manoeuvre and the car would move forward until its path is blocked. It then selects reverse and uses the steering, throttle, and brakes to do the same again. It repeats this as many times as required until it is facing in the opposite direction.
‘SOLO CAR’ ENHANCED SENSING
Jaguar Land Rover has an advanced research program underway to enhance the car’s sensing capability. This project is developing a range of sophisticated sensors to make autonomous cars viable in a range of driving environments and weather conditions.
Creating a car capable of functioning autonomously in all situations requires a fusion of sensors with different attributes including radar, LIDAR, cameras, ultrasonics and structured light technology. Each of these is needed to enable an autonomous car to function in the real world and to ensure the car can make safe and accurate decisions anywhere.
