Abstract: A computerized system onboard a vehicle for automatic radar-based vehicle guidance includes a front-looking radar sensing module. The front-looking radar sensing module comprises a pair of radar sensors. The pair of radar sensors are placed at front of vehicle. The pair of radar sensors emits radar waves at a specified radar frequency and senses reflected radar waves. The radar waves are reflected by a set of radar reflectors placed at the side of a roadway at a distance ahead of the vehicle on the roadway. The front-looking radar sensing module obtains a reflected-radar information from the pair of radar sensors and determines the distance between the vehicle and the radar reflectors ahead of the vehicle at a specified time.

Abstract: A non-transitory computer-readable storage medium storing a set of instructions executable by a processor, the set of instructions, when executed by the processor, causing the processor to perform operations including mapping a memory area storing a segment of code for a kernel of the system during an initialization time of a system. The operations also include executing the segment of code during the initialization time. The operations also include unmapping a portion of the memory area for the kernel after the segment of code has been executed.
