METHODS AND SYSTEMS FOR A STEER-BY-WIRE SYSTEM WITH SENSOR DEVICES
Described is a “steer-by-wire system with sensor devices,” which is an electric power steering system in which a steering assist motor is disposed such that the axis of the steering assist motor is parallel to a rack bar. The system uses an angle sensor in the gear housing to monitor the ball nut angle which provides accurate steer angle information and the required redundancy when used in conjunction with the MPS information. Thus, removing the necessity for the pinion shaft which, in turn, removes the necessity for rack bar preload because there is no interface or required mesh between a pinion shaft and rack bar teeth. Other components within a steer-by-wire system, otherwise necessary, may be similarly removed while utilizing the concepts as described herein.

Battery systems such as those used to power electric vehicles include series of cells that are interconnected to provide sufficient voltage and current. In some circumstances, individual ones of these cells can fail in a so-called thermal event, which causes heating, expansion, and then rupture of the affected cell. Using sensors arranged between the cells (or blocks of cells), the failure point can be detected early to provide ameliorative cooling, electrical disconnection, and warning to occupants of the vehicle to get to a place of safety.
