Problems solved by technology

[0004] At present, the power steering system, which only judges whether the motor is started according to the steering angle, cannot effectively solve the impact of the wide range area on the vehicle during actual driving, causing the motor to start and stop frequently in the wide range area, which increases power consumption and maintenance costs.

Embodiment Construction

[0030] The present invention can be better understood from the following examples. However, those skilled in the art can easily understand that the content described in the embodiments is only for illustrating the present invention, and should not and will not limit the present invention described in the claims.

[0031] The content of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] like figure 1 As shown, in this embodiment, the middle steering position is set, the moment angle (inner circle) is 0°, and the steering angle (outer circle) is 0°.

[0033] like Figure 2~3 As shown, this embodiment sets the torque angle working position. When the torque angle reaches ±4°, the hydraulic power booster drive relay is turned on. At this time, the timer counts for 1 second. After 1 second, if the steering angle does not follow to reach ±4° , the hydraulic booster drive relay remains in the pull-i...
