ERROR DETECTION DEVICE FOR HYBRID VEHICLES AND ERROR DETECTION METHOD

WIPO Patent Application WO/2014/157183

A1

An error detection device comprising: a means that arithmetically calculates the differential rotation between the rotation speed of a motor and the input rotation speed detected by a primary rotation speed sensor; a gear ratio arithmetic calculation means that arithmetically calculates the gear ratio for a continuously variable transmission, on the basis of the input rotation speed detected by the primary rotation speed sensor and the output rotation speed detected by a secondary rotation speed sensor; and an error detection means that determines that the primary rotation speed sensor has an error, if the differential rotation is larger than a prescribed value and the gear ratio is larger than the maximum gear ratio or is smaller than the minimum gear ratio for the continuously variable transmission, when a second clutch is engaged during travel, and determines that the secondary rotation speed sensor has an error, if the differential rotation is no more than the prescribed value and the gear ratio is larger than the maximum gear ratio or is smaller than the minimum gear ratio.
