摘要:
A lead acid battery model suitable for programming on a motor vehicle body computer uses environmental and target battery operating variables for maintaining synchronization of the model with the target battery under actual operating conditions. The model includes a energy flow section with at least two integrators for simulating primary and recovery reservoirs of charge in the battery. An output voltage estimation signal provides a signal for comparison with measured battery voltage for synchronization. Capacity of the reservoirs is generated from manufacturer specifications measured against battery performance.

A cab extender assembly for selectively changing the aerodynamic drag on a vehicle having a longitudinal axis includes a fixed cab extender (12) and at least one track (28) extending generally parallel to the longitudinal axis of the vehicle. An adjustable cab extender (10) has at least one moveable member that is engaged in the track (28). An actuator assembly (56) is configured for selectively reciprocating the adjustable cab extender (10) along the track and with respect to the fixed cab extender.

A heating system (10) for use on an exhaust system (12) having an exhaust gas passageway (14), the engine (16) having a cooling system (38) to circulate a cooling fluid to and from the engine, includes a fuel-dosing member for dosing fuel to the exhaust system to trigger a regeneration event. A particulate filter (34) is located on the exhaust gas passageway downstream of the engine, and an oxidation catalyst member (32) is located upstream from the particulate filter. The oxidation catalyst member (32) oxidizes the fuel dosed to increase the temperature of the exhaust gases. The increased temperature causes a regeneration event at the particulate filter, which further increases the temperature of the exhaust gases. A heat exchanger (36) is located downstream of the particulate filter (34) for capturing heat from the exhaust gases. The heat exchanger (36) has an inlet conduit and an outlet conduit for circulating the cooling fluid from the heat exchanger to the engine cooling system.
摘要:
A steering wheel (20) that has an axis of turning (64) axis for steering a motor vehicle that has an engine, a drivetrain, a transmission that provides different gear ratios for coupling the engine to the drivetrain, and a transmission controller that in an automatic mode automatically shifts the transmission from one gear ratio to another in response to changing vehicle torque requirements and in a manual mode shifts the transmission from one gear ratio to another in response to manual actuation of a shift command device. A module (36) contains both the shift command device (58, 60) and a mode selection device (62) for selecting between the automatic and manual modes.
摘要:
A control system for a hybrid vehicle equipped with power takeoff equipment provides a multi-bus, network environment, integrating operation of a vehicle electric traction motor, power takeoff equipment including prospectively hydraulic motion control equipment and a vehicle thermal engine. The control system is readily programmable to allow reconfiguration depending upon the character of the equipment installed. Efficient utilization of the vehicle's thermal engine and enhanced system robustness is obtained.
摘要:
A tire pressure management system for a tractor/trailer system uses exterior sidewall mounted tire RFID tags, valve mounted tire pressure sensors and transmitters, radio repeaters, a tire pressure management system receiver with controller area network interface, a body computer for execution of software modules of the system and a controller area network for carrying data between the body computer and tire pressure management system receiver. The system provides varying functionality depending upon which elements are present. To deal with absence of a tractor, variation in the complimentary TPMS components installed on the tractor, or lack of any complimentary TPMS components installed on the tractor a trailer mounted repeater includes sufficient local processing power and display capability to alert users of any tire pressure problem on the trailer.
摘要:
A gearshift to transmission controller interface is based on a controller area network (CAN) and a gearshift interface interposed between the gearshift (190) and associated displays and the network bus. The shift controller (90) can be made universal to all transmission types of automated manual transmissions by incorporation of a library program relating to a transmission type.
摘要:
A system and method for alerting responsible personnel to perform a post-trip inspection check for passengers remaining on a bus at the end of a trip by issuing audible and/or visual alerts when the bus is parked and the motor shut off at the end of the trip. The ignition switch (47) must be placed in ACCESSORY position and a park brake applied for the system to be rendered capable of being disarmed by operation of a disarming device (45S) at the rear of the bus. Operation of the disarming device is indicated by a correct sequence of operating conditions of the device, namely first non-actuated, then actuated, and then non-actuated. The system includes a SNOOZE state that allows the ignition switch (47) to be temporarily turned off during a trip and the alert to be stopped by pressing a snooze switch (57).
