ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a starting apparatus in a vehicle for engaging and disengaging a clutch by an actuator which is electronically controlled in accordance with output signal from various detection means which detect the driving states.
SUMMARY OF THE INVENTION
In a vehicle having the above-described automatic control unit for automatically controlling the clutch to engage or disengage in accordance with the driving state of the vehicle based on the output signal from the above-described various state detecting means, it is an object of the present invention to provide a starting apparatus capable of safely starting the engine only under a constant condition, capable of starting the engine even when the control unit is repaired, and capable of finding the trouble of the related detecting means, in view of the automating tendency of the vehicle clutch.
To achieve the above object, there is provided a starting apparatus for a vehicle having an electronically controlled clutch in which the clutch is engaged or disengaged by an electronically controlled actuator in accordance with output signals from various detecting means for detecting driving state, wherein a starter cut relay having normally-closed contacts is connected to an output terminal of an electronic control unit, one of the contacts of the relay is connected to one end of a relay coil of a starter relay connected at the other end of said relay coil to a power source through a key switch, and the other contact of the cut relay is connected to a non-grounded side contact of a neutral relay connected to the power source in series together with a neutral switch.
