A system for controlling multiple vehicle includes a twelve volt (12V)/forty-two volt (42V) battery power distribution system that provides direct current. The system converts single phase alternating current to multiple phase alternating current to simultaneously power multiple vehicle systems. A single pulse width modulation generator converts the direct current from the 12V/42V battery power distribution system to alternating current. This provides one power supply path of alternating current, which has a first phase. A splitter device splits the one power supply path of alternating current into three power paths. A lead/lag circuit is used to shift the alternating current of the second path to a second phase different than the first phase of the first power supply path. A second lead/lag circuit for shifts the alternating current of the third path to a third phase different than the first phase or the second phase. This creates a three-phase alternating current power from a single direct current source. The three-phase alternating current is used to power a plurality of induction motors that operate multiple vehicle systems.

An apparatus for controlling multiple vehicle systems includes a single power supply that provides a direct current source. The power supply is comprised of a thirty-six volt (36 V) battery power distribution system. A converter is electrically connected to the power supply to convert direct current to alternating current. A plurality of induction motors are used to operate various vehicle systems. The motors receive alternating current via electrical connections between the converter and the motors. A central processor is connected to relays sending power to each of the motors and provides control signals to the motors based on input from control members used to activate each of the various vehicle systems. At least one sensor is associated with each of the motors to monitor voltage or current of the respective motor and to generate a diagnostic signal that is sent to the processor. The processor generates a warning signal when any of the diagnostic signals indicates that voltage within the respective motor is outside a predetermined range. A piezoelectric material is associated with each of the motors to provide an internal control signal for the motor. The piezoelectric material can be used to control acceleration or deceleration of the motor based on the rotational force of a rotor within the motor or can be use to activate an auxiliary winding in the motor based on mechanical input to the respective controller.

A plurality of motors for use in driving accessories on a vehicle, are each powered by three-phase current. A single controller controls the supply three-phase current to the plurality of motors. In another aspect of the invention, pseudothree-phase current is created from a direct current voltage source. A chopping circuit chops the voltage into a plurality of pulses, and a phase shift circuit then creates phase-shifted power signals from those pulses. The present invention thus enables the use of three-phase alternating current motors on a vehicle to drive accessories. This reduces the cost and size of the required motors.

The present invention provides a system for automatically shutting down a vehicle. The system includes a vehicle system for performing a vehicle function such as brakes for performing braking of the vehicle. A vehicle control system controls the vehicle system by controlling valve switches or actuators to manipulate the vehicle system. A portable handheld computing device includes a program defining a vehicle shutdown sequence. Preferably, the portable handheld computing device is what is known as a personal digital assistant (PDA), such as a Handspring&reg; or Palmpilot&reg;. A cradle removably receives the portable handheld computing device to connect the portable handheld computing device with the vehicle control system, such as through the vehicle databus. A switch enables the portable handheld computing device to command the vehicle control system to perform the vehicle shutdown sequence. The switch may be an ignition switch, a dedicated vehicle shutdown sequence switch, or an icon on a PDA display touch screen. Once the switch has been actuated, the program residing on the portable handheld computing device commands the vehicle control systems to perform the vehicle shutdown sequence. For example, the vehicle shutdown sequence may command the pneumatic power control system to purge a wet tank to remove the water from the wet tank to prevent it from rusting.

The present invention provides a reconfigurable intermediate panel (RIP) arranged between the cab and the cargo bed of a vehicle. The vehicle has a vehicle body structure that separates the cab and the cargo bed. The RIP is arranged within an opening in the vehicle body structure for providing access to the cab from the cargo bed. The RIP includes a door structure having first and second opposing portions adjacent to opposing sides of the opening when the RIP is in a closed position. A plurality of cable spans the first and second portions for strengthening the door structure and barring the entry of cargo from the cargo bed into the cab when the structure is in the closed position. In one embodiment, the cables extend from opposing portions of a door frame. In another embodiment, the cables are embedded in a plastic panel, which is secured to a door frame. Accordingly, the above invention provides an RIP that provides an improved structural barrier between the cargo bed and the cab from heavy cargo.

Reinforced cargo doors

A vehicle data storage system is provided which includes a plurality of sensors for sensing vehicle operating conditions, such as engine temperature. A control module receives the vehicle operating conditions and translates the vehicle operating conditions into vehicle information. A portable hand held computing device, such as a Handspring&reg; or Palmpilot&reg;, has a data storage device or memory that receives the vehicle information. The data storage device is limited by a particular memory capacity. A secondary storage device receives the vehicle information from the data storage device from the portable hand held computing device when the memory capacity reaches a desired memory capacity level, such as when there is only 10% of the memory left in the data storage device. Additionally, one of the vehicle operating conditions in one of the subsystem control modules may comprise a triggering event. The triggering event may be detecting a high engine temperature in an engine temperature sensor. The subsystem control module then produces a request signal for event data in response to the triggering event. A memory buffer stores the vehicle information from all of the subsystem control modules. The event data is defined by a first predetermined time before the triggering event to a second predetermined time after the triggering event so that the data surrounding the triggering event resides in the memory buffer. The data in the memory buffer is written over by new data unless a request signal is received. A secondary storage device receives the event data in response to the request signal.
