A brake cooling period prediction system for predicting a brake cooling period following a braking event, and including a sensor apparatus in communication with a prediction apparatus. The sensor apparatus has a torque sensor for measuring the torque reacted by a brake during a braking event; a wear sensor for measuring a wear state of the brake; and an environmental sensor for measuring at least one ambient condition of the environment of the brake. The prediction apparatus includes a memory storing information relating to the thermal behavior of the brake; and a controller configured to receive a torque measurement, a wear measurement and an ambient condition measurement from the sensor apparatus; and predict a cooling period based on the received torque, wear and ambient condition measurements, and the information relating to the thermal behavior of the brake.

A remote support system provides support to an autonomous drive system of a vehicle in response to a support request. The remote support may include guiding the autonomous drive system of the vehicle through a hazardous environment. A call to the remote support system may be initiated, for example, via a user interface control button or by scanning a bar code, QR code, or RFID associated with the vehicle on a device that sends the code with vehicle information to the remote support system. The remote support system may determine an urgency of the request to assess whether immediate support should be initiated or whether to first initiate a communication connection with a passenger. Furthermore, an emergency brake system of the vehicle may be triggered by the remote support system or in response to the vehicle losing a connection to the remote support system during a support request.

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.

A remote start-up operating method and a method for preventing parking malfunction during remote start-up is provided. The method includes determining whether a remote start-up ECU receives a remote start-up signal and determining whether the remote start-up ECU receives an electrical signal that indicates whether to operate a parking valve based on a position of a parking lever. An engine start-up signal is then transmitted to an engine ECU.

A vehicle includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator with strokable piston. A pedal feel simulator is coupled to the master cylinder through a switchable valve, the simulator providing a reaction force. An isolation valve closes to isolate the braking circuit from the master cylinder and the simulator circuit. A controller is programmed to place the simulator in fluid communication with an output of the brake pressure generator, and to stroke the piston at a designated diagnostic time. The resulting pressure increase is observed, and the controller checks whether the pressure-increase to piston-stroke relationship is within a predetermined acceptable range for continued operation of a brake-by-wire mode in which the master cylinder is coupled to the simulator circuit and decoupled from the braking circuit.

The disclosure relates to a method for operating a motor vehicle brake system that comprises at least one electronic parking brake having at least one actuator, wherein in the presence of a first switching signal at a switching signal input the actuator is controlled so as to activate the parking brake. It is provided that the switching signal input in a normal operating mode is released so as to apply optional switching signals and in a safety operating mode is set to a second switching signal that is different from the first switching signal so that the process of controlling the actuator so as to activating the parking brake is prevented. The disclosure further relates to a control device for a motor vehicle brake system.

A system for parking control of a vehicle in which a transmission parking configuration is omitted is provided. The system includes a shift by wire device that requests a parking control of the vehicle when a parking stage is input by an operation of a driver. An electronic parking brake operates a brake installed on a drive wheel via a relay which is connected to be in a parking brake state when the electronic parking brake receives the parking control request from the shift by wire device. The shift by wire device switches the relay to directly operate the brake to be in the parking brake state when the shift by wire device receives a failure event, which indicates that a normal operation of the electronic parking brake is impossible, from the electronic parking brake.
