摘要： A number of illustrative variations may include a system and method of controlling vehicle slowing while implementing brake-to-steer functionality that may include providing a feed-forward gain on vehicle propulsion torque to achieve or maintain target longitudinal acceleration and replicate the behavior of a vehicle not using brake-to-steer. The system may manipulate propulsion of the vehicle to manage longitudinal acceleration disturbance and speed disturbance during brake-to-steer.

摘要： A motion control assembly for a steering column assembly includes a rake bracket having a first leg and a second leg. Also included is a clamping mechanism intersecting the upper jacket and positioned on the first leg of the rake bracket, the on-center, single-sided clamping mechanism moveable between a clamped condition and an unclamped condition, the clamped condition securing a lower jacket against telescoping movement relative to an upper jacket. Further included is a mechanical fastener extending through the second leg of the rake bracket and at least partially through the lower jacket and operatively coupled to the lower jacket.

摘要： Technical solutions described herein include a method of controlling, in an electric power steering system, a steering angle according to a target steering angle by computing an initial value of an integral control term in a proportional integral derivative (PID) control loop used to calculate a control output signal, such as a motor torque command. The initial value of the integral control term is computed as a negative of the initial value of the feedforward term minus the initial value of the feedback term. The initial value of the integral control term corresponds to an initial value of a control output. Accordingly, the technical solutions described herein facilitate handling non-zero initial condition in Electric Power Steering angle control.

摘要： Embodiments described herein are for an absolute position sensor system integrated into a steering column assembly. The absolute position sensor system comprises: a sector connected to a rake adjustment mechanism of the steering column assembly and operable to be moved thereby; a gear coupled to the sector and operable to be rotated by the movement thereof; a magnet connected to and retained by the gear such that the magnet rotates responsive to the rotation of the gear; and a sensor device positioned below the magnet and connected to a stationary part of the steering column assembly. The sensor device is configured to: detect an angle of rotation of the magnet, where the angle of rotation of the magnet corresponds to a position of the rake adjustment mechanism.

摘要： A method includes receiving, before a first time, a plurality of sensor values and identifying, based on the plurality of sensor values, a target vehicle in a blind zone of a host vehicle. The method also includes determining, at the first time, that the host vehicle is initiating a steering maneuver and identifying a plurality of time segments between the first time and a second time. The method also includes updating the plurality of sensor values and determining a heading angle of the target vehicle relative to the host vehicle. The method also includes estimating a position of the target vehicle at each time segment of the plurality of time segments and estimating, using each position of the target vehicle at each corresponding time segment of the plurality of time segments, a position of the target vehicle at the second time.

摘要： A method for controlling an electronic power steering system may include receiving, at an electronic power steering controller, at least one signal from at least one sensor and generating, by the electronic power steering controller using the at least one signal, a first autonomous steering command. The method may also include receiving, from a domain controller at the electronic power steering controller, a second autonomous steering command and comparing, by the electronic power steering controller, the first autonomous steering command and the second autonomous steering command. The method may also include selectively controlling, by the electronic power steering controller, the electronic power steering system using one of the first autonomous steering command and the second autonomous steering command, based on the comparison of the first autonomous steering command and the second autonomous steering command.

摘要： According to one or more embodiments, a method includes computing, by a steering system, a model rack force value based on a vehicle speed, steering angle, and a road-friction coefficient value. The method further includes determining, by the steering system, a difference between the model rack force value and a load rack force value. The method further includes updating, by the steering system, the road-friction coefficient value using the difference that is determined.

摘要： A power steering assembly includes an electric motor having an output shaft extending therefrom. The assembly also includes a housing containing a worm gear operatively coupled to a steering shaft, the worm gear rotatable about a worm gear axis. The assembly further includes an electric motor and a worm arranged to engage the worm gear, the worm extending from the output shaft of the electric motor as a single, integrally formed shaft, the single, integrally formed shaft extending axially from a first end to a second end and being cantilevered to allow the second end to deflect. The assembly yet further includes a bushing surrounding a portion of the shaft proximate the second end of the shaft, the bushing and the portion of the shaft defining a clearance therebetween.

摘要： A position measurement system for a steering system includes a steering shaft. The position measurement system also includes a worm gear coupled to the steering shaft. The position measurement system further includes a worm in meshed engagement with the worm gear, the worm driven by a motor. The position measurement system yet further includes a first sensor operatively coupled to the worm to detect an angular position of the worm and the motor that drives the worm. The position measurement system also includes a driving gear coupled to the steering shaft. The position measurement system further includes a spur gear in meshed engagement with the driving gear. The position measurement system yet further includes a second sensor operatively coupled to the spur gear to detect an angular position of the spur gear.
