Ask anyone who is involved in developing automation for vehicles about the sensors required to do the job and they’ll almost invariably tell you that the more the better. And not only more in terms of quantity, but type.

So Bosch has announced that it has developed what it calls “production-ready” lidar sensors—which complement its radar, ultrasonics and camera offerings.

Says Harald Kroeger, Bosch management board member: “By filling the sensor gap, Bosch is making automated driving a viable possibility in the first place.”

Lidar works by sending out laser pulses and then capturing the bounce-back. Measuring the amount of time it takes for the return allows the system to calculate distances. The light can travel long ranges, which means that lidar enhances the amount of time that the vehicle has available to it to take action should it be required.

So far Bosch isn’t providing details on its lidar tech. But given that it introduced radar-controlled adaptive cruise control in 2000, the company has deep expertise in both sensors and the use of those sensors in automated driving systems, so odds are very good that it truly does have something production-ready for Level 3 to 5 automated vehicles. (Odds are also good that it will be initially deployed—for production applications, not simply development—in what are called “Level 2.5” or “Level 2+” applications, where the driver is still in the loop (e.g., systems like the Cadillac Super Cruise).

Bosch is still working on its other sensor tech. In addition to announcing the lidar, it also announced that it has enhanced its camera systems with artificial intelligence: the camera detects objects, then categorizes them (vehicle, pedestrian, bicycle) and measures their movement such that in cases like urban settings where there might be something or someone darting out from behind something else, the camera system can provide a warning or engage automatic emergency braking.

Kroeger: “We want to make automated driving safe, convenient and fascinating. In this way, we will be making a decisive contribution to the mobility of the future.”

Ideally, they’ll make it so good that it is actually boring.


  • The 2017 Kia Sportage

    Kia Motors America COO and executive vice president says this crossover is “crafted for the urban pioneer.” And it is designed and engineered for competing in one of the hottest segments in the overall auto market.

  • NISSAN'S Platform Play

    The mid-size 2005 Pathfinder, Nissan's largest design and development program to date, involved three technical centers, and took 36 months and countless trans-Pacific trips to complete. Though it borrows major components from the full-size Titan pickup and Armada SUV, it's not just a downsized clone.

    The Mazda CX-5 first appeared on the scene in 2012, and for 2017, the vehicle has undergone some major transformations, to enhance what was already a notable small crossover.
