Method and system for providing for vehicle drivability feel after accelerator release in an electric or hybrid electric vehicle
InactiveUS6378636B1Digital data processing detailsPlural diverse prime-mover propulsion mountingDriver/operatorEnergy recovery
The invention is a method and system to provide negative torque to an electric vehicle (EV, FCEV, hybrid electric powertrain (HEV)) powertrain when only the electric motor is engaged and the accelerator pedal is released with the ultimate objective to provide consistent vehicle performance under varying operating conditions. This deceleration is at a calibratable amount for a calibratable time period using a hierarchical strategy employing a variety of means including dissipating the vehicle's kinetic energy as heat in the motor; regenerative braking; and activating a mechanical braking system. This negative torque on the powertrain is provided only briefly thereby reducing the total kinetic energy dissipation. The invention provides the driver a vehicle deceleration response similar in "feel" to releasing the accelerator of a conventional ICE vehicle under all operating modes, while maintaining optimal energy recovery.

Towed vehicles can be extremely heavy. Accordingly, it is too much of a burden to the braking system of a towing vehicle to not have brakes on the towed vehicle. Controlling the brakes of the towed vehicle must be accurately applied otherwise undesirable conditions can be created. There is a need for a method for controlling braking of a towed vehicle. This method comprises receiving a first signal via a communication bus of a towing vehicle, the first signal relating to at least one operating condition of at least one the towing vehicle and a towed vehicle, sending a second signal to brakes of the towed vehicle, the second signal based on said first signal.

Vehicle control system
ActiveUS20040167702A1Improve securityReduce stepsVehicle fittingsDigital data processing detailsDriver/operatorControl system
In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the "cancel" state, the transition to the "in-control, inter-vehicle distance control" sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the "in-control, collision alarm" sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the "in-control, collision avoiding control" sub-state, and a collision avoiding control is performed.

Control apparatus for electric vehicle
ActiveUS20100235043A1Creep travel capabilitySufficient creep torqueVehicle testingRegistering/indicating working of vehiclesElectric vehicleControl theory
A creep travel capability of an electric vehicle is secured when an abnormality occurs in a brake sensor. When an accelerator operation amount reaches 0% in a low vehicle speed region, a target creep torque is set, whereupon a motor-generator is controlled toward the target creep torque. The target creep torque is reduced as a brake pedal is depressed in order to suppress heat generation and the like in the motor-generator during vehicle braking. Hence, in an electric vehicle in which the target creep torque is varied in accordance with the brake operation amount, when an abnormality occurs (step S11) in a brake sensor for detecting a brake operation amount, a preset prescribed creep torque is employed as the target creep torque regardless of the brake operation amount (step S15). The prescribed creep torque is set at a required magnitude for securing the creep travel capability.

A system, apparatus and method provide a means for testing operation of vehicle brake system. More particularly, a brake actuator is automatically commanded to engage a brake disk stack while the vehicle is in a benign state. An engagement force applied to the brake-disk stack by the actuator then is determined, and the engagement force is compared to a first threshold value. If the engagement force is within a predetermined range of the first threshold value, it is concluded that the brake system is operating normally, otherwise it is concluded that the brake system is operating abnormally.

An interface adaptor is provided between the locomotive MU cable and the ECP trainline permitting ECP data from the lead locomotive to be transmitted via the MU cable on trailing locomotives to a train of ECP cars. On the lead locomotive, the HEU Echelon interface is on a suitable line in the MU cable instead of the separate ECP trainline such the trailing locomotives do not require a separate ECP trainline. The adapter generally employs two transceivers configured as back-to-back repeaters to bridge ECP data between the locomotive MU cable and the ECP trainline. A DC--DC converter can be used to provide the ECP trainline voltage, either as 230 VDC or as a lower voltage. In lower voltage systems the converter may be replaced by a voltage regulator, or may be eliminated. In any case, an inductor is employed on the output to provide a high impedance to the overlay transceiver.
