    摘要: The present disclosure is related to a method to control a contactor tip assembly associated with a grid of an electric drive system is provided. The contactor tip assembly includes at least one first contactor tip and at least one second contactor tip. The method includes introducing a delay signal associated with an operation of at least one of the first contactor tip and the second contactor tip. Further, the operation includes a closing event and an opening event thereof. The method also includes controlling the operation of the first and second contactor tips in an alternate manner. Further, a delay is present between a sequential operation of one of the first and second contactor tips and the other of the first and second contactor tips based, at least in part, on the introduced delay signal.

    摘要: In order to provide an electric vehicle drive system capable of promoting improvement in stability of vehicle traveling when stopping a regeneration operation during operation of a regeneration cooperative brake, the electric vehicle drive system, a battery control unit 310, upon detecting that a battery state is an unchargeable state during control of the regeneration cooperative brake, diagnoses whether a battery 300 is chargeable, and upon deciding to be unchargeable from a result of diagnosis, outputs a Fail signal. Then, a rotating electrical machine control unit 210, upon receiving a Fail prediction signal while the regeneration cooperative brake is being controlled, executes loss increase control for increasing an internal loss of a rotating electrical machine 900 and reducing regenerative electric power by a regenerative brake while maintaining torque of the rotating electrical machine 900 at regenerative torque corresponding to regenerative brake force.

    摘要: A railway vehicle brake system includes at least two relay valves in electrical communication with one another and in fluid communication with a brake pipe, at least two friction brake units in fluid communication with each relay valve, and at least one electric brake unit in electrical communication with each relay valve. Upon a failure of one of the electric brake units, the relay valve in communication with the failed electric brake unit sends a signal to at least one other relay valve to provide pressurized fluid to the at least two friction brake units in fluid communication with the at least one other relay valve. The at least two relay valves may include integrated electric relay valves. The at least two friction brake units may include disc brake units. Each relay valve may be positioned between and in fluid communication with the brake pipe and a main reservoir pipe.

    摘要: A failure diagnosis method for a brake system of a vehicle determines whether the failure occurs in a regenerative braking device, a front-wheel friction braking device or a rear-wheel friction braking device. The method may include comparing a driver's required acceleration/deceleration with a current acceleration/deceleration of the vehicle, determining that a failure has occurred in the brake system of the vehicle when the driver's required acceleration/deceleration is different from the current acceleration/deceleration of the vehicle and comparing a driver's required braking torque with a regenerative braking maximum torque, and determining that the failure does not occur in the brake system of the vehicle when the driver's required acceleration/deceleration is substantially equal to the current acceleration/deceleration of the vehicle.

    摘要: A control device for a vehicle includes a motor configured to drive wheels, a high-voltage battery configured to supply electric power to the motor, and a battery charger configured to charge the high-voltage battery by using a power supply outside the vehicle. The control device further includes a failure detection unit configured to detect a specific failure, and a drive prohibition unit configured to prohibit driving of the vehicle. The drive prohibition unit prohibits the driving of the vehicle when the failure is detected by the failure detection unit in an initial check before start of driving of the vehicle and when the high-voltage battery is charged by using the power source outside the vehicle immediately before the initial check.
