Au­tonomous all-ter­rain ca­pa­bil­ity for Land Rover

The Witness - Wheels - - MOTORING -

JAGUAR Land Rover has demon­strated au­tonomous driv­ing tech­nolo­gies that works both on and off road.

Head of re­search at Jaguar Land Rover Tony Harper said the group’s all-ter­rain au­ton­omy re­search isn’t just about the car driv­ing it­self on a mo­tor­way or in ex­treme off-road sit­u­a­tions, but about safely travers­ing any ter­rain or driv­ing sit­u­a­tion.

“We don’t want to limit fu­ture highly au­to­mated and fully au­tonomous tech­nolo­gies to tar­mac.

“When the driver turns off the road, we want this sup­port and as­sis­tance to con­tinue. In the fu­ture, if you en­joy the ben­e­fits of au­tonomous lane keep­ing on a mo­tor­way at the start of your jour­ney, we want to en­sure you can use this all the way to your des­ti­na­tion, even if this is via a rough track or gravel road.”

To en­able this level of au­tonomous all-ter­rain ca­pa­bil­ity, Jaguar Land Rover’s re­searchers are de­vel­op­ing next-gen­er­a­tion sens­ing tech­nolo­gies that will be the eyes of the fu­ture au­tonomous car.

Be­cause the sen­sors are al­ways ac­tive and can see bet­ter than the driver, this ad­vanced sens­ing will ul­ti­mately give a ve­hi­cle the high lev­els of ar­ti­fi­cial in­tel­li­gence re­quired for the car to think for it­self and plan the route it should take, on any sur­face.

3D path sens­ing

The sys­tems in the cars com­bine cam­era, ul­tra­sonic, radar and light and radar (Lidar) sen­sors to give the car a 360-de­gree view of the world around it, with sen­sors so ad­vanced that the car could de­ter­mine sur­face char­ac­ter­is­tics, down to the width of a tyre, even in rain and fall­ing snow, to plan its route.

Ul­tra­sonic sen­sors can iden­tify sur­face con­di­tions by scan­ning up to five me­tres ahead of the car, so Ter­rain Re­sponse set­tings could be au­to­mat­i­cally changed be­fore the car drives from tar­mac to snow, or from grass to sand. This will op­ti­mise all­ter­rain per­for­mance, with­out loss of mo­men­tum or con­trol.

Cam­eras check for pot­holes

Ter­rain-based speed adap­tion (TBSA) uses cam­eras to sense bumpy ter­rain, in­clud­ing un­even and un­du­lat­ing sur­faces and wash­board roads, pot­holes and even stand­ing wa­ter. It is then in­tel­li­gent enough to pre­dict the po­ten­tial im­pact of these sur­faces on the car’s ride and au­to­mat­i­cally ad­just speed to keep pas­sen­gers com­fort­able.

Shar­ing map up­dates

In a world-first off-road demon­stra­tion, Jaguar Land Rover has con­nected two Range Rover Sports to­gether us­ing in­no­va­tive DSRC (Ded­i­cated Short Range Com­mu­ni­ca­tions) tech­nol­ogy to cre­ate an Off-Road Con­nected Con­voy. This wire­less ve­hi­cle-to-ve­hi­cle com­mu­ni­ca­tions sys­tem shares in­for­ma­tion in­clud­ing ve­hi­cle lo­ca­tion, wheel-slip, changes to sus­pen­sion height and wheel ar­tic­u­la­tion, as well as All-Ter­rain Progress Con­trol (ATPC) and Ter­rain Re­sponse set­tings in­stantly be­tween the two ve­hi­cles. — Sup­plied.

Many self-driv­ing car sys­tems are be­ing tested on road, Jaguar Land Rover is the first to take theirs off-road.
