Abstract

The invention discloses a hybrid control system for mode switching of a timely four-wheel drive compound steering system, which includes a sensor module, a data preprocessing module, a hybrid decision-making control module, and a manipulation execution module, and performs data transmission from the sensor module through an electronic auxiliary control unit ECU Process and analyze, obtain the characteristic values ​​of the current working conditions of the vehicle and make corresponding decisions, realize the mode selection of the timely four-wheel drive compound steering system, and complete the two-wheel drive or four-wheel drive of the timely four-wheel drive compound steering system. The invention solves the problem of mode switching and coordination of the timely four-wheel drive compound steering system, satisfies the control performance of the timely four-wheel drive compound steering system, and improves the control stability and intelligence level of the timely four-wheel drive compound steering system.

Description

technical field [0001] The invention belongs to the technical field of vehicle steering systems, and in particular relates to a mode switching hybrid control system of a timely four-wheel drive compound steering system. Background technique [0002] The design of the timely four-wheel drive compound steering system proposed at present not only takes into account that differential steering is likely to affect the stability of the vehicle, the tires wear heavily, and it is difficult for the tires to be in a rolling state in bad weather; The problem of large steering fuel consumption and poor economy makes the vehicle adopt different driving modes under different working conditions to ensure the power and fuel economy of the vehicle, while taking into account the stability and steering flexibility of the vehicle. However, different working conditions should have different control objectives and priorities, so that the switching of the timely four-wheel drive compound steering s...
