The invention relates to an automobile transverse-speed measurement device. Aiming at an existing defect existing in research for an automobile transverse speed, an automobile transverse-speed measurement device is brought forward. The automobile transverse-speed measurement device comprises a left rear vehicle wheel angle speed sensor, a left rear vehicle wheel vertical load sensor, a mass center sensing unit, a calculation unit, a right rear vehicle wheel angle speed sensor, a right rear vehicle wheel vertical load sensor, a vehicle speed sensor, a left front vehicle wheel angle speed sensor, a left front vehicle wheel vertical load sensor, a right front vehicle wheel vehicle speed sensor and a right front vehicle wheel vertical load sensor. The invention further relates to an automobile transverse-speed calculation method. Through usage of the automobile transverse-speed measurement device and the automobile transverse-speed calculation method, according to angle speeds of various vehicle wheels, vertical loads, a transverse swinging angle speed of an automobile, a front wheel steering angle, a longitudinal speed and lateral acceleration, a transverse speed in an automobile driving process, especially a steering process, is calculated. Through mastery of the automobile transverse speed, the active safety control effect of the automobile is effectively improved.
