摘要:
A drive control device for a vehicle drives an engine at a desired fuel consumption. The drive control device includes a map which correlates each engine rotation speed with an evaluation value indicating a fuel consumption when driving the engine at that engine rotation speed. The drive control device calculates a targeted evaluation value Etg between a first evaluation value Elim1 indicating a fuel consumption when driving the engine in the fuel economy mode and a second evaluation value Elim2 indicating a fuel consumption when driving the engine in the acceleration responsive mode. The drive control device calculates a target engine rotation speed Stg correlated to the targeted evaluation value Etg by referring to the map.

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.

A dual clutch transmission includes a transmission control unit that controls action of a first clutch actuator, a second clutch actuator, and a shift mechanism; determines whether or not a clutch torque capacity for an engaging-side clutch has increased to a determination value during a clutch change period; and, if the clutch torque capacity for the engaging-side clutch has increased to the determination value, changes the torque transmission path by reducing the clutch torque capacity of a release-side clutch.

A transmission control device includes even-numbered and odd-numbered transmission gears selected via a shift mechanism and causes the torque capacities of two clutches to be transitioned to a certain proportion until the clutch rotation speed difference of a low-speed gear-side clutch reaches 0 or approximately 0, sets the torque capacity of the clutch on the low-speed gear side to be the total torque capacity of both clutches, and sets the torque capacity of the clutch on the high-speed gear side to 0. The heat load on the clutch at the time when the vehicle starts to move is reduced and the durability thereof is improved, and the clutch can be made smaller and lighter.

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.

A hybrid vehicle enabling reliable travel to the destination in second travel mode in which the vehicle travels with the engine off and enabling more effective use the second travel mode. In this vehicle, a electric power travel mode travelable distance calculation section calculates the travelable distance based on the average traveling consumed current value inputted from average traveling consumed current value calculation section and the battery capacity SOC inputted from a battery capacity calculation section, and outputs the result to a display section. A fuel travelable distance calculation section calculates the remaining travelable distance based on the remaining fuel inputted from a remaining fuel amount measuring section and the fuel consumption inputted from a fuel consumption calculation section, and outputs the result to the display section. The display section displays the remaining travelable distance for the total of the remaining fuel and the battery capacity SOC for traveling, based on the travelable distance inputted from the electric power travel mode travelable distance calculation section and the remaining travelable distance inputted from the fuel travelable distance calculation section.

A hybrid vehicle that can reduce power consumption when an engine of the vehicle is restarted. The hybrid vehicle has a generator-motor that generates electric power. An engine drives the generator-motor. A battery stores the electric power. In one arrangement, the generator-motor starts the engine by being supplied with the electric power stored in the battery. A control device regulates an upper limit of the electric power that is used to activate the generator-motor.

A control device for a dual clutch transmission includes a transmission control unit that determines immobility in an engaging-side clutch in a next stage as sticking and, when the engaging-side clutch in the next stage malfunctions and when a gear in a previous stage is out of engagement, engages the gear in the previous stage and thereafter controls a clutch torque capacity in the previous stage to a predetermined value, and a back torque limiter operates according to a predetermined condition to engage a release-side clutch in the previous stage.
