Closed Loop Control of the EGR Rate Using the Oxygen Sensor

An effective method for reducing NOx emissions from automotive engines is the recirculation of the exhaust gas (EGR) to dilute the induced fresh air charge. EGR systems are currently applied mostly with open-loop control. A new closed-loop control system for EGR rate has been developed. The most important point of this system is use of the feedback signal based on oxygen density at the intake charge for the engine

DEVELOPMENT OF RECOGNITION SYSTEM FOR ICC USING SENSITIVE LASER RADAR

In Japan some ICCs (Intelligent Cruise Control systems) with recognition systems using Laser Radar have been produced since 1995. However these recognitions systems have some improvement challenges: (1) improvement of detectability for less reflective objects; (2) improvement of identification performance of a vehicle to be tracked in the same lane (a target vehicle); (3) improvement of detection performance under bad weather condition. A new recognition system using sensitive laser radar with APD (Avalanche Photo Diode) as a solution for these challenges is being developed. In this paper, the experimental system using sensitive laser radar is described, especially, algorithm for target vehicle recognition and its performance.
