The real slip amount (S) of a torque converter is calculated by subtracting the real input shaft rotational speed (Nr) of an automatic transmission from the engine rotational speed (Ne), which is the rotational speed of a crankshaft. Then, an engine rotational speed for display (Nd) is calculated by adding a slip amount for display (Sp), which is obtained by applying prescribed correction processing to the real slip amount (S). The aforementioned correction processing may be first-order lag filtering, for example. By this means, even if the real slip amount (S) temporarily increases or decreases, temporary increases or decreases in the engine rotational speed for display (Nd) are suppressed. In other words, variation in the engine rotational speed for display (Nd) is suppressed, and it is possible to supply a driver with an engine rotational speed for display (Nd) that visually imparts a sense of direct control without sacrificing drivability. |
