    • The present invention relates to an electrical protective circuit, used when abnormality occurs, in a vibration suppressing apparatus which changes the load torque on a generator such as an alternator fixed on the engine to generate an angle moment on the generator body to cancel rough idling engine vibrations to suppress vehicle body vibrations due to the rough idling. In the inventive vibration suppressing apparatus, a generator is fixed on the engine which generator includes a voltage regulator to control a field winding current such that a fixed voltage is output to a battery. The generation of engine rough idling is detected on the basis of either a change in the engine speed or a change in the engine vibrations. If rough idling is detected, a high voltage circuit is connected to the field winding to increase the field winding current and hence the load torque on the generator. In the inventive protective circuit, the battery voltage is compared with a predetermined reference value when no rough idling is detected. If the battery voltage exceeds the reference value, a changeover signal is generated and the high voltage circuit is disconnected from the field winding in response to the changeover signal.

    • A protective circuit for protecting a main d.c. circuit of the kind comprising a d.c. power source, a d.c. load, a contactor and a chopper. In the protective circuit, a resistor is connected in parallel with the series-connected contactor and load to permit continuous application of power supply voltage across the chopper. A circuit is connected to the connection point of the load and chopper to provide a signal synchronous with on-off of the chopper, and the output signal of this circuit and a signal corresponding to a chopper-on signal are applied to a logic circuit which provides the logical sum of these inputs for the detection of commutation failure of the chopper. The output of the logic circuit turns on a thyristor for deenergizing the contactor thereby disconnecting the load from the power source.

    • The outputting of an output pulse produced in response to the inputting of a data pulse and a clock pulse to a D type flip-flop circuit is repeatedly simulated in a simulation process to extract a pulse time difference between the data pulse and the clock pulse as a timing verification checking value in a checking value extracting process on condition that the level of the output pulse becomes higher than a reference voltage until a simulation completion time and the pulse time difference is within a prescribed range. After the first simulation, an optimum simulation completion time, at which the levels of the data pulse, the clock pulse and the output pulse are respectively set to a constant high value, is determined to be place the optimum simulation completion time between a simulation start time and the simulation completion time, and the level of the output pulse is checked at the optimum simulation completion time in simulations following the first simulation. Therefore, a pulse time difference sufficiently made small can be rapidly and reliably extracted as a timing verification checking value.

    • A braking apparatus for an electric vehicle in which a mechanical anti-lock brake and regenerative braking cooperate with each other to improve a braking performance is realized. On condition that an accelerator is released off, the wheel rotation number is large, and a brake is trod on, a large regeneration mode is selected by a motor controller when a wheel slip is small, and a regeneration mode is selected when the wheel slip is large. When the wheel slip is small, the braking force exerted on each wheel is increased by the brake controller and the regenerative braking force is also increased so that a slip ratio comes quickly closer to 0.2. When the wheel slip is large, the brake controller reduces the braking force so that the slip ratio comes closer to 0.2. In this case, the regenerative braking force is smaller than the above case of the small wheel slip to such an extent that the operation of the brake controller is not disturbed. On condition that the accelerator is released off, the wheel rotation number is large, and the brake is released off, the regeneration mode is selected when the regeneration switch is turned on, and a coasting mode is selected when the regeneration switch is turned off.
