Abstract

The invention discloses an electric assistant steering device and an assembly thereof, comprising a double-motor coaxial steering module, a torsion sensor and a controller. The double-motor coaxial steering module and the torsion sensor are respectively integrated and axially connected with a steering column of a vehicle steering system and are respectively and electrically connected with the controller, wherein the double-motor coaxial steering module comprises a first motor group and one second motor group, both of which are oppositely and coaxially jointed, the first motor group and the second motor group can receive the control of the controller to provide an active steering function and output one assistant force to assist the steering.

Description

technical field [0001] The invention relates to an electric auxiliary steering device, in particular to an electric auxiliary steering device that can be actively controlled. Background technique [0002] A general electric assisted steering system uses the vehicle speed and the driver's output torque as the basis for the output of the auxiliary motor to provide power assistance for the driver when steering. However, when other advanced safety systems are used for active steering control, the driver will feel that the steering wheel is out of control and feel dangerous. For example, in many of the above-mentioned advanced safety systems, the driver usually decides to turn the steering wheel autonomously in an emergency. However, such an autonomous judgment may often cause greater harm. Wrong autonomous judgment of the steering action, so the aforementioned advanced safety system takes back active control of the steering control at critical moments. Although the advanced sa...
