Abstract

A twin clutch controlling apparatus wherein an interposition of a manual operation into an automatic control clutch can be executed smoothly. The twin clutch controlling apparatus includes an AMT controlling unit for controlling a shift actuator and a clutch actuator, and a shift pedal P for carrying out a shifting request to the AMT controlling unit. If, after driving of the shift actuator is started in response to the shifting request by the shift pedal, a clutch lever is operated in a connection direction before a next stage gear is placed into an in-gear state, then the controlling section drives one of an odd number stage side clutch and an even number stage side clutch which corresponds to the gear before the shifting in a corresponding relationship to a manual operation clutch capacity arithmetic operation value.

Dependent claims

A twin clutch controlling apparatus including:

a multi-speed transmission having a plurality of gear trains between a main shaft on the input side and a countershaft on the output side;
a shift actuator, said shift actuator carrying out changeover of a shift stage of the multi-speed transmission;
a twin clutch configured from an odd number stage side clutch and an even number stage side clutch, said twin clutch connecting and disconnecting power transmission between the transmission and an engine;
a clutch actuator, said clutch actuator controlling the twin clutch;
and
a control section controlling the shift actuator and comprising a manual operation clutch capacity arithmetic operational section, a manual operation clutch capacity arithmetic operational section converting an operational amount of a clutch manual operator to a manual operation clutch capacity value (tqcltmt) corresponding to the manual operation, the twin clutch controlling apparatus comprising:
a shift manual operator, said shift manual operator carrying out a shifting request to said control section;
wherein if, said clutch manual operator is operated in a connection direction after driving of the shift actuator is started in response to the shifting request, said control section immediately drive one of said twin clutch corresponding to the gear position before shifting request toward said manual operation clutch capacity value (tqcltmt), without waiting a next stage gear is placed into an in-gear state, wherein:
an auto mode in which the twin clutch is automatically controlled by the control section, a manual mode in which the twin clutch is manually controlled in response to the manual operation clutch capacity value (tacltmt), and a temporary manual mode are provided for a control mode for the twin clutch;
an automatic shift mode and a manual shift mode are provided for a control mode for the multi-speed transmission;
and
wherein the control mode of the twin clutch is set to the manual mode, the control mode of the multi-speed transmission becomes the manual shift mode.
