A vehicular pedal assembly includes a pedal housing, a pedal shaft supported by the pedal housing for rotation about a pedal axis, a pedal arm coupled to the pedal shaft pivotable to drive the pedal shaft to rotate about the pedal axis, and a position sensor assembly coupled to the pedal shaft to determine a rotational position of the pedal shaft. The position sensor assembly includes a target element, a sensor circuit that senses the target element and generates a signal, and a sensor shaft fixed for corotation with the pedal shaft. The target element is positioned on the sensor shaft and rotates with the sensor shaft about a sensor axis to move the target element with respect to the sensor circuit and change the signal generated by the sensor circuit. The pedal shaft is movable along the pedal axis relative to the sensor shaft.

Vehicular pedal assembly

A method and system is provided for determining faults in a vehicle brake system. An electronic processor obtains a brake pedal signal from a brake pedal that indicates a driver intent to brake and obtains a vehicle braking response condition signal from a brake system feedback sensor. The electronic processor determines a fault state when (1) the brake pedal signal is indicative of no brake pedal movement and the vehicle braking response signal is indicative of a vehicle braking response occurring, or when (2) the brake pedal signal is indicative of brake pedal movement and the vehicle braking response condition signal is indicative of no occurrence of a vehicle braking response. The electronic processor controls an output of an audio or visual indication of a fault state and/or controls braking operation of the vehicle in response to the fault state.

Fault detection arrangement for vehicle brake system

Systems and methods for a vehicle pedal assembly and an inductive sensor assembly thereof. The inductive sensor assembly includes a rotary inductive sensor target and a printed circuit board (PCB) positioned opposite the rotary inductive sensor target. The inductive sensor assembly includes a first inductive sensor circuit defined on the PCB. The first inductive sensor circuit includes a first coil circuit including a first coil having a first electrical current in a first flow direction and a second electrical coil having a second current in a second flow direction opposite to the first flow direction. The first inductive sensor circuit is configured such that a rotation of the rotary inductive sensor target induces a change in the first electrical current and the second electrical current within the first coil and the second coil.

Reduced offset error configuration for a rotary inductive sensor

A rotary position sensor comprising a rotatable patterned ring magnet, which in one embodiment is mounted on the output shaft of an actuator, and includes a plurality of pairs of North and South Pole sections extending around the circumference of the ring magnet in an alternating relationship and defining a plurality of circumferentially extending magnetic field switch points spaced predetermined distances on the ring magnet corresponding to a plurality of predetermined unique positions of the ring magnet adapted for sensing by a switch such as Hall Effect switch. In one embodiment, the ring magnet includes a plurality of pairs of North and South Pole sections and switch points on the ring magnet of different predetermined lengths and predetermined locations respectively corresponding to a plurality of predetermined ring magnet positions to be sensed.

Rotary position sensor including switch and patterned magnet

An axial brushless DC motor comprising a stator, a rotor including a magnet, a sleeve bushing extending through the stator and including a pair of opposed distal collars, a motor shaft extends through the sleeve bushing, and a pair of opposed bearings are seated in the respective pair of collars and mount the shaft and a rotor for rotation relative to the sleeve bushing and the stator. The bearings are adapted for thrust, radial support/self-alignment, and angular adjustment of the motor shaft. In one embodiment, a stator overmold member includes a central tube that defines the sleeve bushing and includes a stator shorting ring. In one embodiment, a metal pole piece is seated in a cup-shaped magnet with a rim and the magnetic flux travels through the rim of the magnet and through a magnetic flux sensor.

Axial brushless DC motor

A sensor assembly for sensing a movable object which, in one embodiment, includes a housing defining an interior cavity. A rotor is retained in the cavity. The rotor defines a central bore and a magnet is mounted in an off-center pocket defined by the rotor. The rotor is coupled to the shaft of the movable object whose position is to be measured. A sensor is also retained in the cavity in a relationship at least partially overlying the magnet and adapted to sense at least the direction of the magnetic field generated by the magnet to generate an electrical signal indicative of the position of the movable object. In another embodiment, the rotor and sensor are mounted in separate interior housing cavities separated by an interior housing wall.

Rotary position sensor

An actuator and sensor assembly comprising respective sensor and actuator housings defining an interior chamber. Clips on the sensor housing engage the actuator housing for coupling the sensor and actuator housings together. The sensor housing includes a wall defining a pocket. A connector with a sensor couples to the sensor housing in a relationship wherein the sensor extends into the sensor housing pocket. A movable piston is located in the interior chamber and a tube thereon defines a receptacle for a magnet located adjacent the pocket. The piston is seated on a flexible diaphragm. An actuator shaft includes one end coupled to the piston and an opposite end coupled to a movable object. A plurality of pins in the actuator housing mount the assembly to a support bracket. The sensor senses changes in the magnetic field in response to changes in the position of the magnet relative to the sensor.

Actuator and sensor assembly

A sensor assembly for measuring a linear position includes a slider having a rack gear that engages a pinion gear. The pinion gear is rotatable relative to the slider responsive to linear movement. The pinion gear supports a permanent magnet that generates a magnetic field. Changes in the magnetic field caused by rotation of the pinion gear are sensed by a magnetic field sensor. Signals from the magnetic field sensor are indicative of a rotation of pinion gear and correspond to linear movement of the slider.
