摘要:
A protecting apparatus protects an electronic device which is provided on a vehicle having a storage battery and a solar battery and which inputs output voltages of the storage battery and the solar battery to the electronic device. The protecting apparatus includes a voltage determining unit for determining whether or not the output voltage of the storage battery is normal, an interruption unit for interrupting a path from the solar battery to the electronic device, and a control unit for controlling the interruption unit and thereby interrupting the path when the voltage determination unit determines that the voltage of the storage battery is not normal.

In a vehicle incorporating a control device connected to a solar battery, a storage battery, an operation unit, a first ventilating fan 3 and a second ventilating fan 4, when the operation mode is set by a change-over operation of the operation unit 2 to a parking ventilation mode in which the first and second ventilating fans 3 and 4 are driven by supply of an electromotive force of the solar battery 6, a voltage and a current from the electromotive force of the solar battery 6 are gradually increased and continuously applied to the fan to perform gradual activation of the first ventilating fan 3. Thereafter, a switch unit 26 is closed, and the voltage and the current from the electromotive force of the solar battery are thereby simultaneously applied to the second ventilating fan 4, thus completing activation of the first and second ventilating fans.

In a vehicle incorporating a control device connected to a solar battery, a storage battery, an operation unit and a ventilation unit, a preliminary ventilating device is set to either of charging mode in which the storage battery is charged from the solar battery, forced exhaust mode in which the ventilation unit is driven by power supplied from the storage battery, and in parking ventilating mode in which the ventilation unit is driven by an electromotive force supplied from the solar battery. Charging of the storage battery from the solar battery is possible even when the charging is controlled on the basis of the results of the measurement of the open-circuit voltage of the solar battery. When the solar battery exhibiting a voltage current curve lower than the reference curve is used, the ventilating fan can be activated before the amount of sunlight received by the solar battery has been maximized.

A bending strain measurement apparatus for an abdomen of an anthropomorphic dummy comprises a band constituted of an elastic thin plate member. The band is arranged in a longitudinal direction of the abdomen, has one end thereof fixed in the vicinity of the abdomen of the dummy, and a plurality of gauges are arranged in a longitudinal direction of the band for detecting a bending strain of the abdomen when an obstacle collides with the abdomen. A measuring device measures time history of the bending strain based on bending strain of the respective portions of the band detected by the gauges arranged on the band, as a time transition of the bending strain of respective portions of the band.

A shift control device for a vehicle transmission is provided in which drive means for making a shift drum pivot is connected to the shift drum, wherein the drive means (112) includes a power source (113) disposed on at one end, in the axial direction, of the shift drum (104), and a transmission shaft (117) to which power from the power source (113) is transmitted at the one end, in the axial direction, of the shift drum (104), power from the transmission shaft (117) being transmitted to the other end, in the axial direction, of the shift drum (104). This enables an internal combustion engine to be made compact while avoiding a concentrated disposition of the drive means on one side, in the axial direction, of the shift drum.
