Patent abstract
Methods and systems are provided for regulating engine operating parameters such as exhaust gas recirculation (EGR) based on road roughness conditions. Based on increased road roughness estimation, EGR flow rate may be opportunistically raised, enabling NVH associated with elevated EGR levels to be masked by NVH associated with rough road conditions. In addition, purging of fuel vapors from a canister or a crankcase to the engine may be increased while transmission shift schedules may be advanced so as to complete the shift during the rough road condition.
