    摘要： An improved control system and method for an automatic/semi-automatic transmission system (10) including an automatic change gear transmission (12) driven by a throttle (26) controlled engine (14) is provided. The control system includes a processing unit (42) for receiving inputs indicating at least throttle positon (THL) and vehicle speed (OS) and for determining vehicle acceleration (dOS/dt) and for processing these inputs in accordance with a program or logic rules to determine the selected engaged gear ratio and for issuing command signals to a transmission shifting mechanism (34). The processing unit operates according logic rules so that the control system will execute skip upshifts upon sensing certain predetermined conditions.

    摘要： An improved control system and method for an automatic transmission system (10) including an automatic change gear transmission (12) driven by a throttle (26) controlled engine (14) is provided. The control system includes a processing unit (42) for receiving inputs indicating at least throttle position (THL) and vehicle speed (OS), for determining vehicle acceleration/deceleration (dOS/dt) and for processing these inputs in accordance with a program or logic rules to determine the selected engaged gear ratio and for issuing command signals to transmission system shifting mechanisms (34 and 30). The processing unit includes an operator selected (DOR) set of logic rules by which vehicle performance is maximized and the control will evaluate downshifts at assumed constant vehicle deceleration for a period of time (T) greater than the time required for a single downshift and command a downshift to the lowest gear ratio under the calculated conditions.

    摘要： Tire pressure monitors are incorporated in vehicles having pneumatic tires (14) to continuously or periodically measure the air pressure within the tires and to alert the driver should the pressure in one of the tires fall below a predetermined value. A self-contained battery powered rf transmitter unit (10) is affixed within the drop center (22) of each wheel (12) and includes a pressure sensing switch (84). The battery is contained within a housing (20) mounted to the external surface of the wheel adjacent a fill valve (30) through which electrical wires (50) are routed to the transmitter (11). The transmitter employs a programmable unijunction transistor (PUT) timer (56) which generates a pulse every 33 seconds when the air pressure within the tire is above a prescribed value. A receiver (13), located in the passenger compartment of the vehicle, receives the signal(s) from the transmitters and counts the number of signals received over a given time period established by a second internal PUT timer (266). If fewer than a predetermined number of pulses are received during any given time period, a fault condition is indicated and the driver is appropriately warned. The arrangement of the PUT timer circuits allows for independant selection of their respective peak point voltage, peak point current and valley current.

    摘要： The present invention is a regenerative braking system useful in systems having variable kinetic energy such as vehicles. A DC machine having an independently energized field coil includes a rotor mechanically coupled for rotation at a speed proportional to the velocity of the load. During deceleration the armature is coupled to an inductor and rotational energy provided by the load is converted into magnetic energy stored in the magnetic field of the inductor. To store the energy a short is connected across the inductor, which is preferably operating under superconducting conditions. For acceleration this inductor current is applied to the DC machine to produce a torque for moving the load. The phase reversal required for proper direction of torque is preferably achieved by reversing the direction of field current. The rate of energy transfer and thus the rate of acceleration or deceleration is controlled by controlling the magnitude of the field coil current. A preferred embodiment includes a vehicle battery and motor control for powering the DC machine as the prime mover of the system. A control circuit responsive to vehicle speed, accelerator pedal position, brake pedal position, and the amount of current in the inductor controls switches for proper transfer of energy.
