Filed: 1988-03-30
Abstract: PURPOSE:To select the optimum speed change step even if a change of loadage is large by providing plural sets of speed change programs set by a car velocity and a throttle opening, and switching the program according to a ground clearance detected by ground clearance detecting means. CONSTITUTION:When signals of a car velocity sensor 70, a throttle sensor 80 and ground clearance sensors 91-94 of respective wheels are input to a control unit CPU, the control unit calculates load weight of a vehicle from the ground clearance signals. In case of overload, it is informed by a light emitting diode WL1 and in the case where there is the possibility that load is dropped due to unbalanced load, it is informed by a light emitting diode WL2. Further, according to the car velocity and throttle opening (engine load) from the sensors 70, 80, a designated speed change is conducted according to a speed change program. There are provided plural sets of speed change programs. The selection of a program is switched according to a ground clearance, that is, the load weight. Thus, even if the load weight changes largely, a speed change step for obtaining the optimum accelerating performance and fuel cost performance can be automatically selected without conducting a special switch operation.

Filed: 1978-06-28
Abstract: PURPOSE:To automatically produce alarm sound at a predetermined time when no radio broadcast is present, by providing the selection circuit which selectively selects the radio broadcast reception and the production of alarm sound with the output of the radio signal detection circuit. CONSTITUTION:When the output signal is present from the intermediate frequency amplifying circuit 4, the terminal voltage at the capacitor 13 is high and it is fed to the NAND circuit 16. Other input terminals of the NAND circuit 16 are high in potential since the switch 14 is switched. The output of the circuit 16 is low in potential. A high potential is fed to the control terminal 9c of the switching element 9 via the inverter 17, and the signal of low potential is fed to the control terminal 10c of the switching element 10. Accordingly, the element 9 is conducted, the element 10 is cut off, and only the output of the detection circuit 5 is fed to the audio amplifying circuit 6. When no output signal from the circuit 4 is present, only the element 10 is conducted, and the alarm sound signal of the alarm signal sound production circuit 8 is fed to the amplifying circuit 6.
