    摘要: A control system that prevents an electric vehicle from increasing its speed on a downhill gradient by providing regenerative braking through a traction motor. The system includes an enable circuit that provides an enable signal if certain criteria are met, such as a brake pedal and an acceleration pedal being inactive. The system further includes a controller that is enabled by the enable signal, and receives a vehicle speed signal of the speed of the vehicle. The system also includes a switch that receives the enable signal and the vehicle speed signal. When the enable circuit provides the enable signal, the switch provides a speed set-point to the controller for the last vehicle speed. If the vehicle speed signal goes above the speed set-point, the controller outputs a regenerative braking torque command to the traction motor to reduce the speed of the vehicle to the speed set-point.

    摘要: A method minimizes a driveline vibration and reduces stopping distances in a hybrid electric vehicle (HEV) having a plurality of drive wheels, a friction braking system having antilock braking system (ABS) capability, and an electronically variable transmission (EVT) with two EVT modes. The method automatically shifts the EVT to a predetermined high speed/low torque EVT mode when the ABS is active and when a calibrated maximum deceleration rate is not exceeded. An HEV has a friction braking system with ABS capability and an EVT including a plurality of modes. A controller automatically activates the friction braking ABS in response to a threshold level of slip between the drive wheels and the road surface when the brake pedal is actuated. An algorithm automatically shifts the EVT into one of the high speed/low torque EVT modes when the ABS is activated and the calibrated maximum deceleration rate is not exceeded.

    摘要: An improved brake for winches. The brake has a main brake and an emergency brake. Both brakes are solenoid operated and brake when the power is turned off or fails. Means are provided for slightly delaying the operation of the emergency brake compared to the main brake so that the braking force is applied in stages in an emergency. The brakes are mechanically linked together so that either of the main or emergency solenoids operate both brakes if one of the solenoids fails.
