Abstract: In a start control system for a vehicle, a memory stores a first setting value used to control a clutch to attain a start standby state and a second setting value used to control the clutch to attain a start preparation position. A clutch controller controls the clutch to attain a start standby state based on the first setting value upon determining that the vehicle has proceeded to a start standby period and controls the clutch to attain a start preparation state, in which the distance between the clutch disks is smaller than that in the start standby state, based on the second setting value upon determining the vehicle has proceeded to a start preparation period. The clutch controller controls the clutch such that the distance between the clutch disks is smaller than that in the start preparation state and carries out control such that an engine speed approaches an engine target speed.

Abstract: A start control system stores a map M1 that associates an accelerator position with an initial target speed of an engine and a map M2 that associates an accelerator position with a final target speed of the engine. If it is determined that a vehicle is in a start control period, a target speed of the engine is set to the initial target speed. When the engine speed reaches the initial target speed, the engine target speed is set to the final target speed. The initial target speed is set to a larger value than the final target speed for the same accelerator position.

The drive control device calculates a target engine rotation speed Stg correlated to the targeted evaluation value Etg by referring to the map.

Abstract: A multiple clutch transmission control apparatus performs gear changing smoothly by improving clutch torque control precision, without reducing the speed of gear changing, in a vehicle or the like including a multiple clutch transmission. With this control apparatus, a control unit switches the transmission gear from the previous gear to the next gear by changing the torque transfer path by controlling the first clutch and the second clutch in a clutch changeover period. In the clutch changeover period, the control unit changes the torque transfer path by raising the clutch torque capacity of whichever of the first clutch and the second clutch is the next-gear-side clutch to reach a target value, and then lowering the clutch torque capacity of the previous-gear-side clutch.

Abstract: A control system for a vehicle includes a CPU, a throttle sensor, a shift actuator, and fuel injectors. When the CPU detects a control failure of the throttle valve with a value detected by the throttle sensor, the CPU adjusts the output of the engine by controlling the fuel injectors such that the motorcycle runs with a previously set negative target acceleration. Also, the CPU controls the shift actuator such that the transmission is shifted down in steps as the speed of the motorcycle decreases.
