Jaguar Land Rover recently made the sound of smart technology play, and it was a "transparent engine cover" for a while, and later announced the patent for eye tracking control wiper. Recently, the company released two new technologies - smartphone remote control and autonomous multi-point turning. They were developed by the Jaguar Land Rover UK research team to promote the future of autonomous driving technology.

The Land Rover Range Rover Sport, with remote control technology, shows how drivers can use their smartphones to control cars outside the vehicle. Smartphone applications include steering, acceleration, and brake control, and even switch gear shifts in the vehicle. In this way, if the vehicle is in a more dangerous position, or if the vehicle is more accurately controlled to exit the off-road section, the driver can control the vehicle movement outside and follow the movement, and the maximum speed under remote control conditions is 6.4 km/h. When other vehicles are too close to their own vehicle to open the door and enter the car, the driver can use the smartphone remote control app to pour the vehicle out of the parking space. In the case of such bad road conditions as off-road sections, the driver can act as an inspector outside the vehicle to prevent the vehicle from colliding with obstacles.

In the process of following the vehicle together, the driver can confirm the slope, relative distance, relative angle and other information in real time to ensure that the vehicle is in the most accurate position when climbing the steep slope of sand and gravel. Remote control is also an auxiliary measure for vehicles to wading or crossing a slippery road (caused by mud or snow). The remote control function can only be activated if the driver is within 10 meters of the vehicle and detects the smart key. The remote control system automatically turns off when the driver leaves the detection range or is too close to the vehicle. The future direction of remote control technology should be more automated. Drivers only need to use a mobile phone to send a simple command, the vehicle can successfully complete the remaining items, autonomously crossing obstacles and realizing parking.

Multi-point steering

The multi-point steering function of the Land Rover Range Rover Sport application can automatically control the vehicle to make a 180-degree turn on the road to achieve the direction of the front. The test prototype can handle the most complex road conditions, such as dead ends, congested parking lots, busy sections, and more. The system uses sensors to evaluate the available space to avoid collisions with pedestrians, vehicles and other obstacles. The automatic multi-point steering system controls the gear selection, steering, braking and acceleration operations to complete the steering steering with the optimal number of front and rear movements.

The research team is working hard to develop a system that scans the surrounding environment of the vehicle and promptly informs the driver whether it is safe to take the steering turn. Under the premise that the driver determines the safety of the control, the vehicle will move to the most forward position, then select the reverse gear position, and move to the most backward position through a series of operations of steering, acceleration and deceleration. Repeat the same control forward, and then cycle through until the front is turned to the opposite direction.

Driving a narrow parking space is not a great experience for any driver. Jaguar Land Rover demonstrated the boring elimination of driving through remote control and automatic steering technology and improved driving safety. Research on new technologies can not only help autopilots become a reality, but also improve driving safety and driving pleasure. Sensors and systems that allow autonomous cars to make the right decisions, if applied to conventional models, can help drivers prevent accidents. Autopilot technology and driving pleasure are not contradictory, but should complement each other.

Jaguar Land Rover wants to offer consumers both manual and autonomous modes. Because cars often need to deal with all kinds of bad road conditions and extreme weather, future autonomous vehicles can not only shuttle freely on city streets, but also have to deal with complex off-road conditions, such as heavy rains and strong sunlight, so they need to be developed. A range of sensors that can be used under all conditions, trying to get rid of the dependence of traditional products on lane markings, road infrastructure (such as traffic lights). Engineers at Jaguar Land Rover called the self-driving car a "Solo Car."

Pavement prediction

In addition, Jaguar Land Rover is conducting a cutting-edge technology research project to improve vehicle perception. The project team has developed a number of sophisticated sensor devices that enable autonomous vehicles to cope with a wide range of driving environments and weather conditions. Creating a car that can be driven automatically in any environment requires a large number of different sensors, including radar, laser positioner, camera, ultrasonic, structured light technology.

Jaguar Land Rover, a member of the British Automated Driving Alliance, will participate in advanced driver assistance system technology road tests in Coventry and Milton Keynes, and will undertake evaluation of semi-automatic driving technology and human-machine interface systems. The development of new interconnected car technology is also being carried out in an orderly manner to help the vehicle determine the location and determine the severity of the front pit, the damaged sewer, and the damaged manhole cover, and then share the real-time data to other vehicles through the cloud network, and remind the traffic management department of the timely Carry out maintenance. If an alarm is received in front of the pit, the driver can reduce the speed of the vehicle to avoid the danger; or the vehicle can adjust the suspension setting to reduce the impact of the road surface and make the driving more stable. Such interconnection information can effectively reduce the occurrence of accidents such as punctures and collisions.

The Land Rover Range Rover Aurora and Discover Sport Edition's MagneRide magnetic fluid semi-active suspension damping system uses a more complex sensor to calculate the road surface under the wheel and identify abnormal structures such as pits and manhole covers. By monitoring the movement of the vehicle and the change in suspension height, the system is able to continuously adjust the suspension characteristics, even when driving on uneven roads, to ensure the comfort of the driver and passenger. While the MagneRide shock absorption system provides a relatively smooth travel experience for drivers and passengers, Jaguar Land Rover believes that the information collected by the sensors is converted into big data and shared with other road users. Information interconnection helps reduce the economic losses caused by vehicle failures and makes road maintenance more efficient.

The next phase of the research project was the installation of a new road surface sensing device on the Land Rover Range Rover Aurora test vehicle, including an advanced front stereo digital camera. With the current technology, the most accurate data can be collected only when the vehicle is on a pit or a manhole cover, so it is still necessary to improve the measurement technique to accurately detect the pit by scanning the road ahead so that it can be pre-empted when approaching. Judging its severity is more conducive to the protection of drivers and vehicles. Perceiving road conditions ahead and assessing potential hazards are central to autonomous vehicles. Jaguar Land Rover expects to develop autonomous driving technology that bypasses the dimples without leaving the lanes in order to reduce the risk to other vehicles. If the pit is very severe, the safe driving system can reduce the speed of the vehicle or stop the vehicle to minimize the impact strength of the road, and ultimately achieve a safe and pleasant automatic driving target.

Jaguar Land Rover will work with the Coventry City Council to study how to share road condition information to the traffic management department and identify which data is most valuable to the road maintenance team and then carry out repair work based on priority levels.
