Problems solved by technology

However, the above-mentioned technology only considers the change of the driver's characteristics in different periods and under different road conditions, and does not take into account that different types of drivers also have different driving characteristics; therefore, the above-mentioned technologies all have certain limitations.
[0004] In the existing active steering control, most of them only study the control of the steering system itself, and seldom consider the influence of the driver himself on the steering control

Abstract

The invention discloses an active front wheel steering system based on driver characteristics and a control method thereof. The system comprises a steering wheel, a steering column assembly, a double-row planetary wheel mechanism, a double-motor steering execution device and a steering control unit. The steering wheel is connected with the steering column assembly. The steering column assembly comprises an upper steering column, a torque sensor and a corner sensor. An acting force input by the steering wheel acts on the double-row planetary wheel structure through the upper steering column, and the torque sensor and the corner sensor are fixedly installed on the upper steering column; personalized stability control is performed on different types of drivers so that the driving requirementsof different types of drivers can be met, the control output of the system can be reduced and the steering economy can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, and specifically refers to an active front wheel steering system based on driver characteristics and a personalized control method thereof. Background technique [0002] As one of the key systems of the automobile, the steering system directly determines the comfort, handling stability and active safety of the automobile. Active front wheel steering can control the displacement transmission characteristics of the steering system. Through the variable transmission ratio and active steering intervention control, the ideal steering characteristics can be obtained to improve the handling stability and active driving safety of the car. [0003] In the existing active front wheel steering technology, the Chinese invention patent application number is CN201710291498.5, which discloses a steering stability control system and its control method, which uses a double-row planetary mechan...
