Lexus high-tech road safety

Lexus will partner the Victorian Government in a two-year trial of connected-vehicle technology aimed at reducing road trauma.

Lexus Australia and Telstra will undertake the Advanced Connected Vehicles Victoria (ACV2) trial to test cellular-based communications technology designed to reduce traffic accidents while managing traffic flow to reduce congestion, fuel consumption and emissions.

Two specially-equipped Lexus RX 450h F Sport luxury SUVs will be fitted with sensitive equipment that will enable them to communicate with each other and with roadside infrastructure, using new features of the 4G cellular network.

Chief executive Scott Thompson said Lexus was proud to be involved in this local project aimed at making roads safer and driving more efficient and enjoyable.

“This ground-breaking trial involves our local Connected Vehicle Services department along with VicRoads, the Transport Accident Commission and Telstra,” he said.

Mr Thompson said the extensive active and passive safety features plus the roomy interior of the RX 450h F Sport provides the ideal platform to test cooperative intelligent transport systems using cellular-to-everything technology.

“Lexus self-charging hybrids, such as the RX 450h F Sport, are often chosen to support the trialling of high-tech equipment due to the availability of two power sources – the petrol engine and the special hybrid technology.”

The two Lexus vehicles are already equipped with advanced safety features such as automated lane-keeping, autonomous emergency braking and a forward collision warning system.

Additional vehicle-to-vehicle, vehicle to infrastructure and vehicle-to-network technologies to be trialled with the two vehicles are:

  • Emergency electronic brake light: Alerts drivers to a co-operative vehicle that is braking hard some distance ahead.
  • In-vehicle speed warning: Provides drivers with information about active, static or variable speed limits.
  • Right-turn assist: Alerts drivers to pedestrians or bicycles crossing at an upcoming intersection.
  • Red-light violator warning: Alerts drivers that another co-operative vehicle is likely to run a red light across their path at the intersection ahead.
  • Curve speed warning: An advisory speed limit is displayed when a vehicle is approaching a curve in the road where speed needs to be reduced in adverse conditions.
  • Slow/stopped vehicle: Warns the driver when a vehicle ahead is stopped or travelling slower and there is a risk of rear-end collision.
