Take turn to auxiliary function of the wheel hub bearing 【 Wheel hub. The development of 2019 - 02 - 08 NTN corporation ( Hereinafter referred to as, NTN) Developed with wheel steering Angle adjusting mechanism integration as one of the wheel hub bearing, wheel could carry with steering auxiliary function of the wheel hub bearing 【 Wheel hub. 。 The product is NTN company long-term accumulation of the design, manufacture technology and the combination of motor and the control technology. Previous steering device according to the Angle of the lever operation set of tires to Angle, not when driving into the most appropriate design to cater to advance or to each driving conditions. 【 Wheel hub. Do not change the existing steering can be using in the vehicle's front wheel steering, suspension, individual fixed wheel rotation Angle around each module products. With the runtime handle operation Angle and speed, on the basis of the data will tire rotation Angle correction to the appropriate location. Not only improves the stability of the vehicle's steering performance and high speed, also make the vehicle skids in special cases such as stable, and to improve fuel consumption. About vehicle motion control, NTN and kanagawa engineering university joint research, obtained for the Wheel hub. The control method. Using the control rules of test vehicle, the runtime handle quantity can reduce 4 into operation, carry the Wheel hub. To reduce the driving load. In addition, through the driver handle operation, the responsiveness of the vehicle can be improved about 5, also improve the operability of the drive. In this development in the foreseeable future, fully automated driving for developing safer safety action system also has positive significance. In the future, the proposal to launch this product to the global market, contribute to improve the safety of the car and driving comfort. 【 Wheel hub. Once on May 23 ~ 25 exhibition held in yokohama, 【 People with car technology 2018] And at the same time will also be in the Automotive technology will spring convention 】 About the control technology of the product in the dissertation. The characteristics of the developed product 1. Reduce the driving load: handle operation quantity reduce 4 into the test vehicle wheel hub carrying handle Angle of 98 degrees of 56 degrees ( Change lanes when) 2. The vehicle's responsiveness to improve about 5 into the handle to the response speed of 0. 2 seconds when the wheel hub with 0. 1 second ( Change lanes when) Goods photo specifications vehicles carrying case from above can see right wheel control flow chart
