Jaguar tests autonomous vehicle technology with 100-car fleet

Jaguar Land Rover is exploring how to take autonomous vehicle technology off the paved path. But the company has plans for technology on tarmac, too. The company announced that the Jaguar division will have a fleet of 100 cars testing autonomous technologies on public roads. The testing process will cover a period of four years and begin with vehicle-to-vehicle and vehicle-to-infrastructure communication systems, along with a stereo camera system and autonomous vehicle software. These systems will work together to provide a variety of features that could make their way into future Jaguars and Land Rovers. The first feature in development is called "Roadwork Assist." The system relies on the stereo camera to create a 3D image the car's software can analyze. The software can identify road cones and other barriers associated with construction sites. The car will then alert the driver about entering the construction zone and provide some steering assistance to keep the car centered in its lane. Tony Harper, Jaguar's head of research, said that this system can reduce stress on the driver, and the technology could eventually be used to allow the car to pilot itself through construction zones. Another of Jaguar's proposed features is "Safe Pullaway," which also relies on cameras and software. The Safe Pullaway feature is designed to prevent close-proximity collisions in traffic jams and even in the garage. To do this, the car watches the area immediately ahead of it for obstacles. If the car detects something nearby while the driver adds throttle or shifts into gear, it will apply the brakes to prevent driving into the object. The final project on Jaguar's plate is its "Over the Horizon Warning" system. This will be one of the first features to rely on Jaguar's vehicle-to-vehicle communication technology. The idea is that connected cars in constant communication will give drivers additional warning of upcoming hazards, such as out-of-sight animals and slowed or stopped cars. In Jaguar's example of a stopped car, the stationary vehicle would send a signal alerting approaching cars of the situation. In turn, the approaching vehicles would trigger audible and visual warnings to drivers about the hidden car. Jaguar says that the system could also be applied to emergency vehicles. Emergency vehicles would broadcast a signal to alert drivers well before the lights and sirens get their attention. This would give emergency vehicles a faster, safer path through traffic.

Our love of SUVs is killing people in the streets

Americans are fond of supersized fast-food meals and colossal convenience-store fountain drinks, even though they're clearly bad for our health and U.S. adults keep getting fatter. We also like large vehicles, and our love affair with SUVs is killing people in the streets. According to a recent investigation by the Detroit Free Press/USA Today, the increase in SUV sales over the past several years coincides with a sharp rise in pedestrian deaths in the U.S. — up 46 percent since 2009, with nearly 6,000 people killed in 2016 alone. With SUV sales surpassing sedans in 2014 and pickups and SUVs currently accounting for 60 percent of new vehicle sales, it's no wonder Ford announced in April plans to cease U.S. sales of almost all passenger cars. And this followed Fiat Chrysler's move to virtually an all-truck, -SUV and -crossover lineup. While the Freep/USA Today investigation found that the simultaneous surge in SUV sales and pedestrian deaths comes down to vehicle size, it also points to a lack of action on the part of the National Highway Traffic Safety Administration (NHTSA), even though it knew of the dangers SUVs pose to pedestrians. Also blamed are automakers dragging their feet on implementing active safety features. Using federal accident data, the Insurance Institute for Highway Safety (IIHS) determined that there was an 81 percent increase in single-vehicle pedestrian fatalities involving SUVs between 2009 and 2016. Freep/USA Today's analysis of the same data by counting vehicles that struck and killed pedestrians instead of the number of people killed showed a 69 percent increase in SUV involvement. As far back as 2001, researchers at Rowan University forecasted a rise in pedestrian deaths as Americans began switching to SUVs. "In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans," the researchers wrote, with light trucks comprising SUVs.

Audi and Jaguar Land Rover recalls address seatbelt issues

Audi and Jaguar Land Rover are each recalling several thousand vehicles for separate potential seatbelt issues. The recalls cover the 2022 Audi A3 and S3; 2022 Jaguar F-Type, F-Pace and XF; and the 2022-23 Land Rover Defender, Discovery, Discovery Sport, Range Rover Sport and Range Rover Velar. Examples of these vehicles may have shipped with seatbelt pretensioners that will not function properly in the event of an accident.  Audi is recalling its sedans for tensioner devices that may not adequately restrain drivers or passengers during a crash. The issue was discovered during Korean market crash testing of the high-performance RS 3.  "The seat belt tensioner in the affected vehicles serve the purpose of holding the passenger in his position in the seat," Audi said in its defect report to NHTSA. "In the event of a crash, the retention force of the seat belt may not reach the intended level. As a result, the position of the body can be further to the front of the seat, which leads to a negative influence on the whole restraint system, increasing the risk of injury." A different company, Jaguar Land Rover (JLR), meanwhile, also has an issue with a batch of pretensioners installed in its cars and SUVs. Pretensioners are the devices that fire off to rapidly retract the seatbelt when a crash is detected. Most utilize an explosive charge and pressure tube JLR says that some pretensioner devices provided by one of its suppliers may not have properly-specified pressure tubes that may not channel the gasses to the retraction mechanism correctly.  "A damaged front seat belt pretensioner tube may have been installed on the seat belt retractor," JLR's report said. "This may result in a reduced level or complete loss of pre-tensioning in the event of a crash and increased occupant injury." Owners of the models included in both recall campaigns should receive notices from the manufacturers in the coming months.  Related video: Recalls Audi Jaguar Land Rover Ownership Safety SUV Sedan
