In this electric linear motion actuator, a linear motion mechanism and an electric motor are arranged in line along the same axis, which is an axis of a rotation input/output shaft of the linear motion mechanism. The electric motor includes a stator and a rotor which are arranged such that the directions of magnetic poles thereof for generating interlinkage magnetic flux contributing to a torque are parallel to a rotation shaft of a motor. The rotor has torque generating surfaces at both faces in the axial direction thereof. The stator has first and second excitation mechanisms arranged on both sides in the axial direction of the rotor. The first and second excitation mechanisms have independent first and second system coil groups. A power supply system for independently supplying power to the first and second system coil groups is provided.

Systems and methods for a braking a vehicle. In one example, the braking system includes a friction braking system, a regenerative braking system, and an electronic processor. The electronic processor is communicatively coupled to the friction braking system and the regenerative braking system. The electronic processor is configured to receive a driver brake request and determine a brake failure state. The brake failure state indicates a brake failure. In response to determining the brake failure state, the electronic processor applies a braking force based on the driver brake request. The braking force includes a frictional braking force generated by the friction braking system and a regenerative braking force generated by the regenerative braking system.

A method of citing a parking violation includes locating a removable locking device around a wheel of the vehicle. The locking device is located to permit the mobility of the vehicle but act as a nuisance when in motion. A driver is permitted to settle the infraction through multiple ways wherein the driver pays a fee for the infraction and a core fee for the locking device. The core fee may be refunded upon successful return of the locking device to a collection unit. The act of ticketing and securing the vehicle are done in a concurrent set of steps.

A device for a hydraulic actuating system, e.g., a motor vehicle brake, a clutch or a gear selector, may include the following components arranged in one housing, forming a main module: at least one pressure supply device driven by an electric motor drive, and a valve arrangement comprising at least one solenoid valve. The device may further include an electrical control unit (ECU) and valve output stages and sensors. The main module may be electrically and/or hydraulically connected to at least one further system component, which system component may include and actuating device and a travel simulator.

A method of sensing wheel rotation can include: sensing magnetic force information in an environment of a wheel by a magnetometer to obtain measured magnetic force information; generating relative magnetic force information by performing mathematical operation processing in accordance with the measured magnetic force information, where the relative magnetic force information does not change with geomagnetic field and does change with a rotation angle of a wheel; and obtaining angle information related to the rotation angle of the wheel in accordance with the relative magnetic force information.

A control system and method control release of a braking device from a wheel or disc. Release of the braking device is slowed or stopped based on a speed at which the braking device is released. The braking device may include a return limiting device through which a rod is configured to move. The return limiting device permits the rod to slide within the return limiting device while the brake pad holder releases from the wheel or disc no faster than a designated speed, but engages and restricts movement of the rod within the return limiting device while the brake pad holder releases from the wheel or disc faster than the designated speed.
