Disclosed are an in-wheel working device and an automobile including the in-wheel working device. According to one aspect of the present disclosure, provided is an in-wheel working device including a rotation detection sensor coupled to a wheel bearing. The rotation detection sensor includes: a sensor stator coupled to an outer race of the wheel bearing; and a sensor rotor coupled to a hub of the wheel bearing. The sensor stator includes a printed circuit board (PCB) substrate having a surface on which a coil pattern made of a metal material is formed.

Described embodiments provide circuits, systems and methods for detecting and communicating fault conditions. In an embodiment, an integrated circuit includes a fault detector to detect a fault condition of the integrated circuit and a controller to generate output data of the integrated circuit. An output generator generates an output signal of the integrated circuit. The output signal is generated at a first set of output levels based upon the output data when the fault detector does not detect the fault condition, and the output signal is generated at a second set of output levels based upon the output data when the fault detector detects the fault condition.

A motor gearbox assembly is provided for a vehicle having two wheels on opposite sides of the vehicle. The assembly includes two independent drive systems that each include an electric motor and an associated gear train, each drive system being configured to independently drive one of the wheels. The assembly further includes a common housing that receives the motors and the gear trains such that the gear trains are at least partially positioned between the motors. Furthermore, at least portions of the drive systems have generally inverse orientations in a longitudinal direction of the vehicle when the motor gearbox assembly is mounted on the vehicle.

An electronic control unit executes gradual reduction control when a friction clutch is to be maintained in a fully engaged state such that an input rotary member and an output rotary member rotate integrally. As a result, a motor current supplied to a motor is adjusted to a lower current value. Thus, an average current value of the motor current supplied to the motor when the friction clutch is to be maintained in the fully engaged state is appropriately reduced.

A vehicle with deployable pliable fairing skirts and a controller for controlling deployment of the skirts are provided. The pliable fairing skirts are deployable over openings of wheel wells for the vehicle to provide additional streamlining for the vehicle. The pliable fairing skirts are stowable when the brakes of the vehicle may benefit from additional cooling airflow. The skirts are also stowable when environmental conditions may result in damage to the skirts or when steerable wheels of the vehicle would protrude from the opening.

A system includes detecting devices secured respectively on wheels of a vehicle at different angular positions, sensors assigned respectively to the wheels and a control unit. Each detecting device emits a detecting signal when disposed at a first position and a second position different from the first position by a first angle . The first position where each detecting device emits the detecting signal during a current rotation cycle of the respective wheel differs from that during a next rotation cycle of the respective wheel by a second angle. The control device analyzes the detecting signals and tooth number signals from the sensors to associate the detecting devices respectively with the sensors.

A driving support apparatus is provided with: a first controller programmed to perform a first control, which is to make a speed of a vehicle not to exceed a predetermined speed; a second controller programmed to perform a second control, which is a driving support control that is different from the first control; a preventer configured to prevent the second control on the basis of an operation of an accelerator by an occupant of the vehicle; and a prevention reducer configured to control the preventer to hardly prevent the second control if the first control is performed, in comparison with when the first control is not performed.

A device for determining a cinematic magnitude of a bicycle and a rate of the pedal-thrust exerted by an user on the pedals of the bicycle includes a sensor of the bicycle, adapted to be associated to the bicycle, suitable for detecting the bicycle cinematic magnitude (.sub.i) and for generating a signal representative of the bicycle cinematic magnitude; a filter connected to the sensor of the bicycle cinematic magnitude, configured for receiving at the input the signal representative of the bicycle cinematic magnitude (.sub.i) and for supplying, at the output, an optimized signal (.sub.opt) of the bicycle cinematic magnitude; and a module for the frequency-analysis of the optimized signal (.sub.opt) of the bicycle cinematic magnitude, connected to the said filter

A speed control system for electric bicycles includes a bicycle having pedals, a motor and a battery which provides electric power to the motor. The bicycle includes a speed detector to detect speed of the bicycle to create a current speed value. A controller is electrically connected to the motor, the battery and the speed detector. The controller has a preset constant-speed setting value. The controller receives the current speed value from the speed detector, and compares the current speed value with the preset constant-speed setting value to adjust output or the motor and the battery. The controller changes the output of the motor and the battery according to the current speed so that the motor assists the rider to operate the bicycle instantly.
