Abstract

The invention relates to an adjusting system and an adjusting method capable of automatically and quantitatively adjusting an automobile wheel distance. The adjusting system comprises a half shaft with a telescopic spline pair, an ultrasonic detector and a speed sensor installed on a front frame of the automobile, a display screen installed in the automobile, an electronic control unit electrically connected with the display screen, four stepping motors connected with the electronic control unit, a harmonic gear reducer, a gear and rack transmission pair, a rolling device and a return device.After power of an automobile engine is transmitted to a differential mechanism of a drive axle, the power is transmitted to wheels through the two-telescopic spline type half shaft. The adjusting device can accurately and quantitatively adjust the wheel distance according to the real-time speed of an automobile and the distance of a front curve or an obstacle, and different algorithms can be set in an ECU according to needs so as to change the control mode of wheel distance change.

Description

technical field [0001] The invention belongs to the field of intelligent control, and relates to an automobile wheelbase adjustment device, in particular to an adjustment system and an adjustment method capable of automatically and quantitatively adjusting the automobile wheelbase. Background technique [0002] At present, the wheelbase of existing automobiles is fixed, and cannot be changed according to changes in use requirements during use. However, the difference in wheel base will directly affect the driving performance. For example, the wider the track of the front wheels of the car, the smoother the car will be when turning, and the better the lateral stability; but the wider the track of the front wheels, the better the steering accuracy. The lower it is, the larger the road width will be occupied. In addition, the size of the wheelbase will also affect the passability and driving safety of the car on narrow roads. [0003] Chinese patent CN 206826318 U discloses "...
