摘要： Magnetorheological-damper-based steering apparatus and methods for reducing steering wheel jerk resulting from off-road wheel impact are described. An example steering damper apparatus includes a magnetorheological (MR) rotary damper to be operatively coupled to a steering column shaft. The example steering damper apparatus further includes a sensor to detect an angular velocity associated with the steering column shaft. The example steering damper apparatus further includes a controller to energize the MR rotary damper in response to determining that the angular velocity exceeds an angular velocity threshold. The angular velocity threshold is associated with steering wheel jerk resulting from an off-road wheel impact.

摘要： In a steer by wire and idle stop vehicle, the idle stop is terminated if the steering wheel (11) is turned by more than a prescribed threshold value. For the purpose of preventing consumption of power by a steering actuator and preventing an unexpected steering action upon termination of the idle stop, the engine restart threshold value (Δθth) is varied depending on the direction of the change of the steering angle from the start of the idle stop operation. In particular, if the change (Δθ) of the steering angle is in the direction to increase the steering angle from the value (θs) at the start of the idle stop operation, the engine restart threshold value is raised. If the change of the steering angle is in the direction to decrease the steering angle from the value at the start of the idle stop operation, the engine restart threshold value is lowered.

摘要： In an example embodiment, a vehicle guidance system includes a memory including computer-readable instructions stored therein and a processor. The processor is configured to execute the computer-readable instructions to estimate a wheel angle of a vehicle based on at least a first value, the first value being a hand wheel based estimate of the wheel angle, and adjust steering commands for steering the vehicle based on the estimated wheel angle to permit the vehicle to move along a set path.

摘要： A column tube switch module is radially and axially fixed to a column tube and is supported at the same time on a bearing arranged on the steering spindle. A centering device secures a stator radially to the column tube when a force is acting coaxially on the longitudinal axis of the steering spindle. A steering angle sensor is provided whose fixed part is connected to the stator-end bearing while its rotating part is held so as to be capable of being driven by the steering wheel hub.

摘要： To provide a rudder angle sensor with high accuracy, it is constituted such that a storage means capable of storing a correction value to correct a rotational delay of a driven gear relative to a main drive gear caused by a backlash at a time of reverse of a steering shaft is provided, a calculation means corrects a measured result of a measuring mechanism based on the correction value stored in the storage means, and thereby, a rotation angle of the steering shaft can be calculated. The measured result of the driven gear obtained by the measuring mechanism is corrected based on the correction value, and therefore, the backlash existing between the main drive gear and the driven gear can be matched completely or approximately. Namely, the high accuracy of the rudder angle sensor is realized.

摘要： A position sensor for determining the angular position of a steering wheel. The shaft of the steering wheel is connected to a code disk and turn ring of the sensor so that when steering wheel is rotated, the coded disk and turn ring are also rotated. The code disk is a flat circular disk having a series of cut-outs or bits around its perimeter. A light emitting diode shines a light through the cut-outs and is read by a photo detector which determines the angular position of the code disk. The turn ring is fitted on the outside of the code disk and rotates in a hypocycloidic circle so that for every full revolution of the code disk, the turn ring rotates through a smaller angle. The turn ring is placed over a series of Hall sensors to determine the number of revolutions of the code disk.
