Document Type and Number:
Japanese Patent JP4274352
Kind Code:
B2
Abstract:
A vehicle speed display apparatus capable of displaying an accurate vehicle speed in either 2WD mode or in 4WD mode. A vehicle speed calculating unit 51 calculates the vehicle speed, according to the output from a wheel rotational speed sensor 22. A 2WD/4WD detecting unit 52 switches the destination of the vehicle speed calculated by the vehicle speed-calculating unit 51 between a 2WD correcting unit 53 and a 4WD correcting unit 54, depending whether the vehicle is traveling in 2WD mode or in 4WD mode. The 2WD correcting unit 53 corrects the vehicle speed in the 2WD mode using a first correction coefficient for the 2WD mode, and the 4WD correcting unit 54 corrects the vehicle speed in the 4WD mode using a second correction coefficient for the 4WD mode. The corrected vehicle speed is displayed by a vehicle speed display unit 55.
