<P>PROBLEM TO BE SOLVED: To provide a DPF travel-time regeneration control system capable of stably raising the temperature even during travel and capable of decreasing the frequency of DPF regeneration when the vehicle is stopped. <P>SOLUTION: If the DPF (5) needs to be regenerated, the vehicle is traveling on cruise control, and the exhaust temperature detected by an exhaust temperature sensor (11) is higher than a threshold value, then fuel is injected into the exhaust pipe by a fuel injection means (7), and if the exhaust temperature is lower than the threshold value, the exhaust temperature is raised by operating the exhaust brake without injecting fuel into the exhaust pipe. <P>COPYRIGHT: (C)2013,JPO&INPIT |
