A vehicle includes a motor and a controller. The controller is programmed to, responsive to an autonomous braking request and a predicted average braking torque associated with the request having a magnitude less than a powertrain regenerative torque limit, brake the vehicle only with the motor according to a torque profile adapted from a most efficient torque profile of the motor so as to have an average value falling within a specified range of the average braking torque.

A vehicle stability control system includes a signal collection sensor and a vehicle controller (10). The signal collection sensor is configured to collect a vehicle condition information parameter, and the vehicle controller (10) is configured to calculate a control yaw moment according to the vehicle condition information parameter. The control yaw moment is used to cancel a difference between an estimated yaw moment and an actual yaw moment. The vehicle controller (10) is further configured to determine according to the vehicle condition information parameter whether the vehicle (100) is in a stable region or a non-stable region in the case of tire blow-out, and allocate the control yaw moment to four wheels (101) according to a vehicle stability condition, thus implementing vehicle stability control. A vehicle stability control method and a vehicle (100) with the vehicle stability control system are also disclosed.

Provided are a brake system, a brake device, and a method of controlling brakes for railroad cars in which control can be multiplexed with a simple configuration. In a brake system 1 for railroad cars includes brake control devices 11, 12, 13 provided in railroad cars 101, 102 103 respectively that form a unit 104. Each brake control device 10 (11, 12, 13) is capable of outputting information of the corresponding car (101, 102, 103) to the other brake control devices 10 through a transmission device 20. The brake control device 10 can calculate a total necessary braking force value BRA required for braking all of the cars 101, 102 103 using the information output from the other brake control devices 10 to the transmission device 20.

A motor having an electromagnetic brake is provided to ensure a braking torque even when power is off. The motor assembly comprises a drive motor and an electromagnetic brake. A thrust generating mechanism translates rotational motion of a brake motor to linear motion to generate thrust force for moving any one of brake stator and brake rotor of the electromagnetic brake thereby maintaining frictional contact therebetween to stop rotation of a motor shaft.

Method and apparatus for powering electric motors. The electric motors are connected to a DC power supply by a parallel modular converter that includes a plurality of parallel power converters that convert the DC power to AC power. The parallel modular converter selectively connects different parallel power converters to different ones of the electric motors to provide an adequate supply of electrical power to meet the load conditions of the electric motor. As the load conditions of the electric motors dynamically change, the parallel modular converter can selectively connect certain PPCs to different motors to satisfy the changing load conditions.
