Vehicle rear wheel steering assisting control system and control method thereof

Abstract

The invention relates to a vehicle rear wheel steering assisting control system and a control method thereof. The problem that the automobile cornering is unsafe is solved. According to the technical scheme, a controller, a data execution module, a data acquisition module, a rear wheel active steering device, a vehicle wheel drift angle measuring instrument and a rotation speed measuring instrument are included, wherein the vehicle wheel drift angle measuring instrument is mounted at the position of one front wheel for measuring an steering angle of front wheels; the rotation speed measuring instrument is also mounted at the position of one front wheel for measuring the speed of the front wheels; the output ends of the vehicle wheel drift angle measuring instrument and the rotation speed measuring instrument are electrically connected with the data acquisition module; the data acquisition module is electrically connected with the controller; the controller is electrically connected with the control end of the data execution module; the rear wheel active steering device is mounted at the position of one automobile rear wheel; the control end of the rear wheel active steering device is electrically connected with the output end of the data execution module; the controller is electrically connected with an ECU of an automobile; each automobile seat is internally provided with a weight sensor; the weight sensors are electrically connected with the controller.

Description

technical field [0001] The invention relates to a control method and system for auxiliary steering of rear wheels of a vehicle, in particular to a control system and method for auxiliary steering of rear wheels of an automobile equipped with an active steering device for rear wheels. Background technique [0002] Nowadays, with the development of the economy and the substantial improvement of people's living standards, cars have basically entered thousands of households. Cars have become the mainstream mode of transportation. Whether it is a family car, a large truck or a vehicle, it occupies half of the transportation industry by virtue of its irreplaceable advantages. With the continuous expansion of urbanization, the number of family cars is increasing day by day, the road covers a large area, and there are countless large and small curves. When cornering, the vehicle will be in danger of rollover due to the different turning radius at different speeds, but if the vehicl...
