Problems solved by technology

[0002] Multi-axle trucks refer to trucks with more axles, such as multi-axle heavy-duty trucks with more than 5 axles. At present, in the chassis of some trucks with more than 5 axles (including 5 axles), grouping is used. Steering technology, the grouping steering technology refers to using the 1st and 2nd axle wheels of the car as the front set of steering wheels, and the rear 2nd axle wheels of the car as the rear set of steering wheels. An effective means of steering flexibility and handling stability. The existing technology to realize group steering control usually includes two states of front group steering and front and rear group steering at the same time, and the switching between these two states is currently under manual control. mode, but the manual control mode will increase the driver's driving burden, and it is easy to cause misoperation

Abstract

The invention provides an automatic control device of rear-group steering of a multi-axle heavy vehicle. The automatic control device comprises a front-group rotary angle sensor, a rear-group rotary angle sensor, a rear-group rotary angle control unit, and a main controller. The front-group rotary angle sensor is used for collecting front-group rotary angle data; the rear-group rotary angle sensor is used for collecting rear-group rotary angle data; the rear-group rotary angle control unit is used for adjusting the rotary angle of the rear group; and the main controller is used for carrying out calculation according to the front-group rotary angle data collected by the front-group rotary angle sensor to obtain a rear-group expected rotary angle, comparing the rear-group rotary angle data collected by the rear-group rotary angle sensor with the rear-group expected rotary angle to obtain a rear-group rotary angle adjusting difference value, and controlling the rear-group rotary angle control unit to carry out corresponding rotary angle adjustment automatically according to the rear-group rotary angle adjusting difference value. Therefore, misoperation of the manual control mode can be avoided; the wheel rotary angle error is effectively reduced; the tyre wearing degree is reduced; and the driving safety of the vehicle chassis can be guaranteed.
