PCT No. PCT/JP95/00614 Sec. 371 Date Feb. 26, 1996 Sec. 102(e) Date Feb. 26, 1996 PCT Filed Mar. 30, 1995 PCT Pub. No. WO95/27130 PCT Pub. Date Oct. 12, 1995The invention relates to a method for the determination of a rough road in a vehicle with a multi-cylinder internal combustion engine (1) mounted thereon. With a view to economically performing determination of a rough road with high accuracy, a revolution variance (IAC,VAC) is detected with respect to each cylinder in the internal combustion engine (1). Based on detection of revolution variance states, each of which indicates a deterioration in combustion, in plural cylinders, the vehicle with the internal combustion engine (1) mounted thereon is determined or estimated to be running on a rough road. |
