Self-driving vehicle watches human to cope better in strange environments

Self-driving vehicles can learn from human drivers, then sometimes out-drive them, according to US Army research. The team designed an algorithm that allows an autonomous ground vehicle to improve its existing navigation systems by watching how a human driver remote-controlled the same vehicle, calling the approach ‘adaptive planner parameter learning from demonstration’ – APPLD. The approach ...

Automotive always-on dc-dc controllers need only a few µA

Renesas has introduced a pair of automotive dc-dc converter chips with low operating current for ‘always-on’ applications. Both are designed to work with external mosfet power stages. ISL78264 is a 50W-200W synchronous dual buck controller intended to manage the intermediate first stage dc-dc conversion, stepping down the 12V battery system to 5V and 3.3V to ...
