摘要： A vehicle control system configured to carry out an energy saving control is provided. The vehicle control system is applied to a vehicle having an engine, a torque converter, a transmission and a clutch device selectively connecting a turbine runner to the transmission. The vehicle control system executes the energy saving control by controlling both an operating condition of the engine and an engagement condition of the clutch device or only the engagement condition of the clutch device. The vehicle control system comprises a clutch control means configured to increase the torque transmitting capacity of the clutch device using an increasing amount of a speed of the turbine runner as a target value, when bringing the clutch device into engagement being in disengagement during execution of the energy saving control.

摘要： A shift controller for an automatic transmission mechanism is configured such that when the engine is in a driven state in which the engine is driven by a travel inertia force or the like and an accumulated pressure amount of the accumulator is equal to or less than a predetermined threshold, the excessive engine brake force, which is generated due to the accumulation of at least a portion of the hydraulic pressure generated from the mechanical hydraulic pump in the accumulator, is inhibited or reduced by conducting upshifting that relatively decreases the gear ratio of the automatic transmission mechanism. Therefore, the generation of the excessive engine brake force can be inhibited or reduced even when the engine is in the driven state and pressure accumulation is performed.

摘要： If it is determined that a malfunction has occurred in an electrical hydraulic pump and the hydraulic fluid is not supplied to a high hydraulic pressure supplied portion from the electrical hydraulic pump, the hydraulic fluid is supplied to the high hydraulic pressure supplied portion from a mechanical hydraulic pump that usually supplies the hydraulic fluid to a low hydraulic pressure supplied portion. In this case, the hydraulic pressure that is generated by the mechanical hydraulic pump is increased by increasing the output from the engine that drives the mechanical hydraulic pump.
